Most patients who developed these infections were taking concomitant immunosuppressants such as methotrexate or corticosteroids. Reported infections included: Active TB, which may present with pulmonary or extrapulmonary disease. Patients should be tested for latent TB before tofacitinib extended-release tablets use and during therapy. Treatment for latent infection should be initiated prior to tofacitinib extended-release tablets use. Invasive fungal infections, including cryptococcosis and pneumocystosis. Patients with invasive fungal infections may present with disseminated, rather than localized, disease. Bacterial, viral, including herpes zoster, and other infections due to opportunistic pathogens. The risks and benefits of tofacitinib extended-release tablets treatment should be carefully considered prior to initiating therapy in patients with chronic or recurrent infection. Patients should be closely monitored for the development of signs and symptoms of infection during and after tofacitinib extended-release tablets treatment, including the possible development of TB in patients who tested negative for latent TB infection prior to initiating therapy. If a serious infection develops, interrupt tofacitinib extended-release tablets until the infection is controlled [see Warnings and Precautions (5.1) ] . MORTALITY In a large, randomized, postmarketing safety study in rheumatoid arthritis (RA) patients 50 years of age and older with at least one cardiovascular (CV) risk factor comparing tofacitinib tablets 5 mg or 10 mg twice a day to tumor necrosis factor (TNF) blockers, a higher rate of all-cause mortality, including sudden CV death, was observed with tofacitinib tablets 5 mg or 10 mg twice a day [see Warnings and Precautions (5.2) ] . Tofacitinib 10 mg twice daily and tofacitinib extended-release tablets 22 mg once daily dosages are not recommended for the treatment of RA, psoriatic arthritis (PsA), or ankylosing spondylitis (AS) [see Dosage and Administration (2.3) ] . MALIGNANCIES Malignancies, including lymphomas and solid tumors, have occurred in patients treated with tofacitinib and other Janus kinase inhibitors used to treat inflammatory conditions. In RA patients, a higher rate of malignancies (excluding non-melanoma skin cancer (NMSC)) was observed in patients treated with tofacitinib tablets 5 mg or 10 mg twice a day compared with TNF blockers [see Warnings and Precautions (5.3) ] . Lymphomas and lung cancers were observed at a higher rate in patients treated with tofacitinib tablets 5 mg or 10 mg twice a day in RA patients compared to those treated with TNF blockers. Patients who are current or past smokers are at additional increased risk. MAJOR ADVERSE CARDIOVASCULAR EVENTS RA patients 50 years of age and older with at least one cardiovascular risk factor, treated with tofacitinib tablets 5 mg or 10 mg twice daily, had a higher rate of major adverse cardiovascular events (MACE) (defined as cardiovascular death, myocardial infarction, and stroke), compared to those treated with TNF blockers. Patients who are current or past smokers are at additional increased risk. Discontinue tofacitinib in patients that have experienced a myocardial infarction or stroke [see Warnings and Precautions (5.4) ] . THROMBOSIS Thrombosis, including pulmonary embolism, deep venous thrombosis, and arterial thrombosis have occurred in patients treated with tofacitinib and other Janus kinase inhibitors used to treat inflammatory conditions. Many of these events were serious and some resulted in death. RA patients 50 years of age and older with at least one cardiovascular risk factor treated with tofacitinib tablets 5 mg or 10 mg twice daily compared to TNF blockers had an observed increase in incidence of these events. Avoid tofacitinib in patients at risk. Discontinue tofacitinib and promptly evaluate patients with symptoms of thrombosis [see Warnings and Precautions (5.5) ] . WARNING: SERIOUS INFECTIONS, MORTALITY, MALIGNANCY, MAJOR ADVERSE CARDIOVASCULAR EVENTS, and THROMBOSIS See full prescribing information for complete boxed warning. Increased risk of serious bacterial, fungal, viral, and opportunistic infections, including tuberculosis (TB), leading to hospitalization or death. Interrupt tofacitinib extended-release tablets treatment if serious infection occurs until the infection is controlled. Test for latent TB before and during therapy; treat latent TB prior to use. Monitor all patients for active TB during treatment, even patients with initial negative latent TB test.

Tofacitinib extended-release tablets: 11 mg tofacitinib ( 3 )" ], "contraindications": [ "4 CONTRAINDICATIONS None. None ( 4 )" ], "warnings_and_cautions": [ "5 WARNINGS AND PRECAUTIONS Serious Infections: Avoid use of tofacitinib extended-release tablets during an active serious infection, including localized infections. ( 5.1 ) Gastrointestinal Perforations : Promptly evaluate patients at increased risk for gastrointestinal perforation who present with new onset abdominal symptoms.( 5.6 ) Hypoglycemia in Patients with Diabetes: Consider increased monitoring of blood glucose; advise patients with diabetes to notify their healthcare provider if they develop signs or symptoms of hypoglycemia. ( 5.8 ) Laboratory Monitoring : Recommended due to potential changes in lymphocytes, neutrophils, hemoglobin, liver enzymes and lipids. ( 5.9 ) Vaccinations : Avoid use of live vaccines concurrently with tofacitinib extended-release tablets.( 5.10 ) 5.1 Serious Infections Serious and sometimes fatal infections may occur with tofacitinib extended-release tablets. Serious and sometimes fatal infections due to bacterial, mycobacterial, invasive fungal, viral, or other opportunistic pathogens have been reported in patients receiving tofacitinib. The most common serious infections reported with tofacitinib included pneumonia, urinary tract infection, cellulitis, herpes zoster, bronchitis, septic shock, diverticulitis, gastroenteritis, appendicitis and sepsis. Among opportunistic infections, tuberculosis and other mycobacterial infections, cryptococcosis, histoplasmosis, esophageal candidiasis, pneumocystosis, multi−dermatomal herpes zoster, cytomegalovirus infections, BK virus infection, and listeriosis were reported with tofacitinib. Some patients have presented with disseminated rather than localized disease, and were often taking concomitant immunomodulating agents such as methotrexate or corticosteroids. In the UC population, treatment with tofacitinib tablets 10 mg twice daily was associated with greater risk of serious infections compared to 5 mg twice daily. Additionally, opportunistic herpes zoster infections (including meningoencephalitis, ophthalmologic, and disseminated cutaneous) were seen in patients who were treated with tofacitinib tablets 10 mg twice daily. Other serious infections that were not reported in clinical studies may also occur (e.g., coccidioidomycosis). Avoid use of tofacitinib extended-release tablets in patients with an active, serious infection, including localized infections. The risks and benefits of treatment should be considered prior to initiating tofacitinib extended-release tablets in patients: with chronic or recurrent infection who have been exposed to tuberculosis with a history of a serious or an opportunistic infection who have resided or traveled in areas of endemic tuberculosis or endemic mycoses; or with underlying conditions that may predispose them to infection. Closely monitor patients for the development of signs and symptoms of infection during and after treatment with tofacitinib extended-release tablets. Interrupt tofacitinib extended-release tablets if a patient develops a serious infection, an opportunistic infection, or sepsis. In patients who develop a new infection during treatment with tofacitinib extended-release tablets, promptly complete diagnostic testing appropriate for an immunocompromised patient; initiate appropriate antimicrobial therapy, and monitor the patients closely. Caution is also recommended in patients with a history of chronic lung disease, or in those who develop interstitial lung disease, as they may be more prone to infections. Risk of infection may be higher with increasing degrees of lymphopenia and consideration should be given to lymphocyte counts when assessing individual patient risk of infection. Discontinuation and monitoring criteria for lymphopenia are recommended [see Dosage and Administration (2.3, 2.4) ] . Tuberculosis Evaluate and test patients for latent or active tuberculosis (TB) infection prior to and per applicable guidelines during administration of tofacitinib extended-release tablets. Consider anti-TB therapy prior to administration of tofacitinib extended-release tablets in patients with a past history of latent or active TB in whom an adequate course of treatment cannot be confirmed, and for patients with a negative test for latent TB but who have risk factors for TB infection. Consultation with a physician with expertise in the treatment of TB is recommended to aid in the decision about whether initiating anti-TB therapy is appropriate for an individual patient. Monitor patients closely for the development of signs and symptoms of TB, including patients who tested negative for latent TB infection prior to initiating therapy. Treat patients with latent TB with standard antimycobacterial therapy before administering tofacitinib extended-release tablets. Viral Reactivation Viral reactivation, including cases of herpes virus reactivation (e.g., herpes zoster), were observed in clinical studies with tofacitinib. Postmarketing cases of hepatitis B reactivation have been reported in patients treated with tofacitinib. The impact of tofacitinib on chronic viral hepatitis reactivation is unknown. Patients who screened positive for hepatitis B or C were excluded from clinical trials. Perform screening for viral hepatitis in accordance with clinical guidelines before starting therapy with tofacitinib extended-release tablets. The risk of herpes zoster is increased in patients treated with tofacitinib and appears to be higher in patients treated with tofacitinib in Japan and Korea. 5.2 Increased Risk of Mortality Increased risk of mortality may occur with tofacitinib. Adult patients with rheumatoid arthritis (RA), 50 years of age and older, with at least one cardiovascular risk factor treated with tofacitinib tablets 5 mg or 10 mg twice a day had a higher observed rate of all-cause mortality, including sudden cardiovascular death, compared to those treated with TNF blockers in a large, randomized, postmarketing safety study (RA Safety Study 1). The incidence rate of all-cause mortality per 100 patient-years was 1.23 for tofacitinib tablets 10 mg twice a day, 0.88 for tofacitinib tablets 5 mg twice a day, and 0.69 for TNF blockers [see Clinical Studies (14.5) ] . Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with tofacitinib extended-release tablets. Tofacitinib 10 mg twice daily (or tofacitinib extended-release tablets 22 mg once daily) dosages are not recommended for the treatment of RA, PsA, or AS [see Dosage and Administration (2.3) ]. For the treatment of UC, use tofacitinib tablets/tofacitinib extended-release tablets at the lowest effective dose and for the shortest duration needed to achieve/maintain therapeutic response [see Dosage and Administration (2.4) ] . 5.3 Malignancy and Lymphoproliferative Disorders Malignancies and lymphoproliferative disorders may occur with tofacitinib. Malignancies, including lymphomas and solid cancers, were observed in clinical studies of tofacitinib [see Adverse Reactions (6.1) ]. Other malignancies were observed in tofacitinib clinical studies and the postmarketing setting, including, but not limited to, lung cancer, breast cancer, melanoma, prostate cancer, and pancreatic cancer. In RA Safety Study 1, a higher rate of malignancies (excluding non-melanoma skin cancer (NMSC)) was observed in patients treated with tofacitinib tablets 5 mg or 10 mg twice a day compared with TNF blockers. The incidence rate of malignancies (excluding NMSC) per 100 patient-years was 1.13 for tofacitinib tablets 10 mg twice a day, 1.13 for tofacitinib tablets 5 mg twice a day, and 0.77 for TNF blockers. Patients who are current or past smokers are at additional increased risk [see Clinical Studies (14.5) ]. Lymphomas and lung cancers, which are a subset of all malignancies in RA Safety Study 1, were observed at a higher rate in patients treated with tofacitinib tablets 5 mg twice a day and tofacitinib tablets 10 mg twice a day compared to those treated with TNF blockers. The incidence rate of lymphomas per 100 patient-years was 0.11 for tofacitinib tablets 10 mg twice a day, 0.07 for tofacitinib tablets 5 mg twice a day, and 0.02 for TNF blockers. The incidence rate of lung cancers per 100 patient-years among current and past smokers was 0.59 for tofacitinib tablets 10 mg twice a day, 0.48 for tofacitinib tablets 5 mg twice a day, and 0.27 for TNF blockers [see Clinical Studies (14.5) ]. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with tofacitinib extended-release tablets, particularly in patients with a known malignancy (other than a successfully treated NMSC), patients who develop a malignancy while on treatment, and patients who are current or past smokers. Tofacitinib 10 mg twice daily (or tofacitinib extended-release tablets 22 mg once daily) dosages are not recommended for the treatment of RA, PsA, or AS [see Dosage and Administration (2.3) ]. Non-Melanoma Skin Cancer Non-melanoma skin cancers (NMSCs) have been reported in patients treated with tofacitinib tablets. Periodic skin examination is recommended for patients who are at increased risk for skin cancer.In the UC population, treatment with tofacitinib tablets 10 mg twice daily was associated with greater risk of NMSC than treatment with placebo. 5.4 Major Adverse Cardiovascular Events Major adverse cardiovascular events may occur with tofacitinib. In RA Safety Study 1, patients with RA who were 50 years of age and older with at least one cardiovascular risk factor and treated with tofacitinib tablets 5 mg or 10 mg twice daily had a higher rate of major adverse cardiovascular events (MACE) defined as cardiovascular death, non-fatal myocardial infarction (MI), and non-fatal stroke, compared to those treated with TNF blockers. The incidence rate of MACE per 100 patient-years was 1.11 for tofacitinib tablets 10 mg twice a day, 0.91 for tofacitinib tablets 5 mg twice a day, and 0.79 for TNF blockers. The incidence rate of fatal or non-fatal myocardial infarction per 100 patient-years was 0.39 for tofacitinib tablets 10 mg twice a day, 0.36 for tofacitinib tablets 5 mg twice a day, and 0.2 for TNF blockers [see Clinical Studies (14.5) ]. Patients who are current or past smokers are at additional increased risk. Consider the benefits and risks for the individual patient prior to initiating or continuing therapy with tofacitinib extended-release tablets, particularly in patients who are current or past smokers and patients with other cardiovascular risk factors. Inform patients about the symptoms of serious cardiovascular events and the steps to take if they occur. Discontinue tofacitinib extended-release tablets in patients that have experienced a MI or stroke. Tofacitinib 10 mg twice daily (or tofacitinib extended-release tablets 22 mg once daily) dosages are not recommended for the treatment of RA, PsA, or AS [see Dosage and Administration (2.3) ]. 5.5 Thrombosis Thrombosis may occur with tofacitinib. Thrombosis, including pulmonary embolism (PE), deep venous thrombosis (DVT), and arterial thrombosis, have occurred in patients treated with tofacitinib and other Janus kinase (JAK) inhibitors used to treat inflammatory conditions. Many of these events were serious and some resulted in death [see Warnings and Precautions (5.2) ]. Patients with RA 50 years of age and older with at least one cardiovascular risk factor treated with tofacitinib tablets 5 mg or 10 mg twice daily compared to TNF blockers in RA Safety Study 1 had an observed increase in incidence of these thrombotic events. The incidence rate of DVT per 100 patient-years was 0.28 for tofacitinib tablets 10 mg twice a day, 0.22 for tofacitinib tablets 5 mg twice a day, and 0.16 for TNF blockers. The incidence rate of PE per 100 patient-years was 0.49 for tofacitinib tablets 10 mg twice a day, 0.18 for tofacitinib tablets 5 mg twice a day, and 0.05 for TNF blockers [see Clinical Studies (14.5) ]. Tofacitinib 10 mg twice daily (or tofacitinib extended-release tablets 22 mg once daily) dosages are not recommended for the treatment of RA, PsA, or AS [see Dosage and Administration (2.3) ]. In a long-term extension study in patients with UC, five cases of pulmonary embolism were reported in patients taking tofacitinib 10 mg twice daily, including one death in a patient with advanced cancer. Promptly evaluate patients with symptoms of thrombosis and discontinue tofacitinib extended-release tablets in patients with symptoms of thrombosis. Avoid tofacitinib extended-release tablets in patients that may be at increased risk of thrombosis.For the treatment of UC, use tofacitinib tablets or tofacitinib extended-release tablets at the lowest effective dose and for the shortest duration needed to achieve/maintain therapeutic response [see Dosage and Administration (2.4) ]. 5.6 Gastrointestinal Perforations Gastrointestinal perforations may occur with tofacitinib. Events of gastrointestinal perforation have been reported in clinical studies with tofacitinib tablets, although the role of JAK inhibition in these events is not known. In these studies, many patients with RA received background therapy with nonsteroidal anti-inflammatory drugs (NSAIDs). There was no discernable difference in frequency of gastrointestinal perforation between the placebo and the tofacitinib tablets treatment groups in clinical trials of patients with UC, and many of them were receiving background corticosteroids. Promptly evaluate patients treated with tofacitinib extended-release tablets who may be at increased risk for gastrointestinal perforation (e.g., patients with a history of diverticulitis or taking NSAIDs) and who present with new onset abdominal symptoms for early identification of gastrointestinal perforation [see Adverse Reactions (6.1) ]. 5.7 Hypersensitivity Reactions Hypersensitivity reactions may occur with tofacitinib. Reactions such as angioedema and urticaria that may reflect drug hypersensitivity have been observed in patients receiving tofacitinib. Some events were serious. If a serious hypersensitivity reaction occurs, promptly discontinue tofacitinib extended-release tablets while evaluating the potential cause or causes of the reaction [see Adverse Reactions (6.2) ]. 5.8 Hypoglycemia in Patients with Diabetes Hypoglycemia, including severe hypoglycemia, has been reported following initiation of tofacitinib and other JAK inhibitors in patients with diabetes. During treatment with tofacitinib extended-release tablets, consider increased monitoring of blood glucose as clinically indicated in patients with diabetes. Advise patients with diabetes to notify their healthcare provider if they develop signs or symptoms of hypoglycemia. 5.9 Laboratory Abnormalities Laboratory abnormalities may occur with tofacitinib. Lymphocyte Abnormalities Treatment with tofacitinib tablets was associated with initial lymphocytosis at one month of tofacitinib tablets treatment followed by a gradual decrease in mean absolute lymphocyte counts below the baseline of approximately 10% during 12 months of therapy. Lymphocyte counts less than 500 cells/mm 3 in these patients were associated with an increased incidence of treated and serious infections. Monitor lymphocyte counts at baseline and every 3 months thereafter. Avoid initiation of tofacitinib extended-release tablets treatment in patients with a low lymphocyte count (i.e., less than 500 cells/mm 3 ). In patients who develop a confirmed absolute lymphocyte count less than 500 cells/mm 3 , treatment with tofacitinib extended-release tablets is not recommended. Neutropenia Treatment with tofacitinib tablets was associated with an increased incidence of neutropenia (less than 2000 cells/mm 3 ) compared to treatment with placebo. Monitor neutrophil counts at baseline and after 4-8 weeks of treatment and every 3 months thereafter. Avoid initiation of tofacitinib extended-release tablets treatment in patients with a low neutrophil count (i.e., ANC less than 1000 cells/mm 3 ). For patients who develop a persistent ANC of 500 to 1000 cells/mm 3 , interrupt dosing until ANC is greater than or equal to 1000 cells/mm 3 . In patients who develop an ANC less than 500 cells/mm 3 , treatment with tofacitinib extended-release tablets is not recommended. Anemia Monitor hemoglobin at baseline and after 4-8 weeks of treatment and every 3 months thereafter. Avoid initiation of tofacitinib extended-release tablets treatment in patients with a low hemoglobin level (i.e., less than 9 g/dL). Interrupt treatment with tofacitinib extended-release tablets in patients who develop hemoglobin levels less than 8 g/d L or whose hemoglobin level drops greater than 2 g/dL on treatment until hemoglobin values have normalized. Liver Enzyme Elevations Treatment with tofacitinib tablets was associated with an increased incidence of liver enzyme elevation compared to treatment with placebo. Most of these abnormalities occurred in studies with background DMARD therapy (primarily methotrexate). Routine monitoring of liver tests and prompt investigation of the causes of liver enzyme elevations is recommended to identify potential cases of drug-induced liver injury. If drug-induced liver injury is suspected, interrupt the administration of tofacitinib extended-release tablets until this diagnosis has been excluded. Lipid Elevations Treatment with tofacitinib tablets was associated with dose-dependent increases in lipid parameters including total cholesterol, low-density lipoprotein (LD-L) cholesterol, and high-density lipoprotein (HD-L) cholesterol. Maximum changes in these lipid parameters were generally observed within 6 weeks. There were no clinically relevant changes in LDL/HDL cholesterol ratios. The effect of these lipid parameter elevations on cardiovascular morbidity and mortality has not been determined. Perform assessment of lipid parameters approximately 4-8 weeks following initiation of tofacitinib extended-release tablets therapy. Manage patients according to clinical guidelines [e.g., National Cholesterol Educational Program (NCE-P)] for the management of hyperlipidemia. 5.10 Vaccinations Avoid use of live vaccines concurrently with tofacitinib extended-release tablets. Prior to initiating tofacitinib extended-release tablets therapy, update immunizations in agreement with current immunization guidelines. The interval between live vaccinations and initiation of tofacitinib extended-release tablets therapy should be in accordance with current vaccination guidelines regarding immunosuppressive agents. 5.11 Risk of Gastrointestinal Obstruction with Tofacitinib Extended-Release Tablets- A Non-Deformable Extended-Release Formulation Gastrointestinal obstruction may occur with tofacitinib extended-release tablets. Avoid use of tofacitinib extended-release tablets in patients with pre-existing severe gastrointestinal narrowing (pathologic or iatrogenic). There have been rare reports of obstructive symptoms in patients with known strictures in association with the ingestion of other drugs utilizing a non-deformable extended-release formulation." ], "adverse_reactions": [ "6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Serious Infections [see Warnings and Precautions (5.1) ] Increased Risk of Mortality [see Warnings and Precautions (5.2) ] Malignancy and Lymphoproliferative Disorders [see Warnings and Precautions (5.3) ] Major Adverse Cardiovascular Events [see Warnings and Precautions (5.4) ] Thrombosis [see Warnings and Precautions (5.5) ] Gastrointestinal Perforations [see Warnings and Precautions (5.6) ] Hypersensitivity Reactions [see Warnings and Precautions (5.7) ] Hypoglycemia in Patients with Diabetes [see Warnings and Precautions (5.8 )] Laboratory Abnormalities [see Warnings and Precautions (5.9) ] Most common adverse reactions are: RA, PsA, and AS: Reported in ≥2% of adult patients treated with tofacitinib tablets monotherapy or in combination with DMARDs: upper respiratory tract infection (URI), nasopharyngitis, diarrhea, and headache. ( 6.1 ) UC: Reported in ≥ 5% of adult patients treated with either tofacitinib tablets and ≥1% greater than reported in patients treated with placebo: nasopharyngitis, elevated cholesterol levels, headache, URI, increased blood creatine phosphokinase, rash, diarrhea, and herpes zoster.

The clinical studies described in this subsection were conducted using tofacitinib tablets and/or tofacitinib oral solution. Adverse Reactions in Adults with Rheumatoid Arthritis In RA Safety Study 1, 1,455 adults were treated with tofacitinib 5 mg twice daily, 1,456 adults were treated with 10 mg twice daily, and 1,451 adults were treated with a TNF blocker for a median of 4 years [see Clinical Studies (14.5) ] . A dosage of tofacitinib 10 mg twice daily is not recommended for the treatment of RA because of increased risks [see Dosage and Administration (2.3) and Warnings and Precautions (5) ] . For the treatment of adults with moderately to severely active RA [see Indications and Usage (1.1) ] , the recommended dosage of tofacitinib is 5 mg twice daily and the recommended dosage for tofacitinib extended-release tablets is 11 mg once daily. The safety of tofacitinib was also evaluated in two Phase 2 and five Phase 3 double-blind, placebo-controlled, multicenter trials in patients with RA. In these trials, adults were randomized to receive: Tofacitinib (monotherapy) 5 mg twice daily (292 patients) or 10 mg twice daily (306 patients), In combination with DMARDs (including methotrexate), tofacitinib 5 mg twice daily (1044 patients) or 10 mg twice daily (1043 patients and Placebo (809 patients). All seven trials included provisions for patients taking placebo to receive treatment with tofacitinib at Month 3 or Month 6 either by patient response (based on uncontrolled disease activity) or by design, so that adverse events cannot always be unambiguously attributed to a given treatment. Therefore, some analyses that follow include patients who changed treatment by design or by patient response from placebo to tofacitinib in both the placebo and tofacitinib group of a given interval. Comparisons between placebo and tofacitinib groups were based on the first 3 months of exposure, and comparisons between tofacitinib 5 mg twice daily and tofacitinib 10 mg twice daily were based on the first 12 months of exposure. The long-term safety population includes all adults with RA who participated in a double-blind, placebo-controlled trial (including earlier development phase studies) and then participated in one of two long-term safety studies. The design of the long-term safety studies allowed for modification of tofacitinib doses according to clinical judgment. This limits the interpretation of the long-term safety data with respect to dose. The most common serious adverse reactions were serious infections [see Warnings and Precautions (5.1) ]. The proportion of patients who discontinued treatment due to any adverse reaction during the 0 to 3 months exposure in the double-blind, placebo-controlled trials was 4% for tofacitinib-treated patients and 3% for placebo-treated patients. Overall Infections In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, the overall frequency of infections was 20% and 22% in the tofacitinib 5 mg twice daily and tofacitinib 10 mg twice daily groups, respectively, and 18% in the placebo group. The most commonly reported infections with tofacitinib were upper respiratory tract infections, nasopharyngitis, and urinary tract infections (4%, 3%, and 2% of patients, respectively). Serious Infections : In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, serious infections were reported in 1 patient (0.5 events per 100 patient-years) who received placebo and 11 patients (1.7 events per 100 patient-years) who received tofacitinib 5 mg or 10 mg twice daily. The rate difference between treatment groups (and the corresponding 95% confidence interval) was 1.1 (-0.4, 2.5) events per 100 patient-years for the combined tofacitinib 5 mg twice daily and 10 mg twice daily group minus placebo. In the seven placebo-controlled trials, during the 0 to 12 months exposure, serious infections were reported in 34 patients (2.7 events per 100 patient-years) who received tofacitinib 5 mg twice daily and 33 patients (2.7 events per 100 patient-years) who received tofacitinib 10 mg twice daily. The rate difference between tofacitinib doses (and the corresponding 95% confidence interval) was -0.1 (-1.3, 1.2) events per 100 patient-years for tofacitinib 10 mg twice daily minus tofacitinib 5 mg twice daily. The most common serious infections included pneumonia, cellulitis, herpes zoster, and urinary tract infection [see Warnings and Precautions (5.1) ]. Tuberculosis : In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, tuberculosis (TB) was not reported in patients who received placebo, tofacitinib 5 mg twice daily, or tofacitinib 10 mg twice daily. In the seven placebo-controlled trials, during the 0 to 12 months exposure, TB was reported in 0 patients who received tofacitinib 5 mg twice daily and 6 patients (0.5 events per 100 patient-years) who received tofacitinib 10 mg twice daily. The rate difference between tofacitinib doses (and the corresponding 95% confidence interval) was 0.5 (0.1, 0.9) events per 100 patient-years for tofacitinib 10 mg twice daily minus tofacitinib 5 mg twice daily. Cases of disseminated TB were also reported. The median tofacitinib exposure prior to diagnosis of TB was 10 months (range from 152 to 960 days) [see Warnings and Precautions (5.1) ]. Opportunistic Infections (excluding tuberculosis) : In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, opportunistic infections were not reported in patients who received placebo, tofacitinib 5 mg twice daily, or tofacitinib 10 mg twice daily. In the seven placebo-controlled trials, during the 0 to 12 months exposure, opportunistic infections were reported in 4 patients (0.3 events per 100 patient-years) who received tofacitinib 5 mg twice daily and 4 patients (0.3 events per 100 patient-years) who received tofacitinib 10 mg twice daily. The rate difference between tofacitinib doses (and the corresponding 95% confidence interval) was 0 (-0.5, 0.5) events per 100 patient-years for tofacitinib 10 mg twice daily minus tofacitinib 5 mg twice daily. The median tofacitinib exposure prior to diagnosis of an opportunistic infection was 8 months (range from 41 to 698 days) [see Warnings and Precautions (5.1) ]. Malignancies In the seven placebo-controlled trials in patients with RA, during the 0 to 3 months exposure, malignancies excluding NMSC were reported in 0 patients who received placebo and 2 patients (0.3 events per 100 patient-years) who received either tofacitinib 5 mg or 10 mg twice daily. The rate difference between treatment groups (and the corresponding 95% confidence interval) was 0.3 (-0.1, 0.7) events per 100 patient-years for the combined tofacitinib 5 mg and 10 mg twice daily group minus placebo. In the seven placebo-controlled trials, during the 0 to 12 months exposure, malignancies excluding NMSC were reported in 5 patients (0.4 events per 100 patient-years) who received tofacitinib 5 mg twice daily and 7 patients (0.6 events per 100 patient-years) who received tofacitinib 10 mg twice daily. The rate difference between tofacitinib doses (and the corresponding 95% confidence interval) was 0.2 (-0.4, 0.7) events per 100 patient-years for tofacitinib 10 mg twice daily minus tofacitinib 5 mg twice daily. One of these malignancies was a case of lymphoma that occurred during the 0-to-12-month period in a patient treated with tofacitinib 10 mg twice daily. The most common types of malignancy, including malignancies observed during the long-term extension in tofacitinib-treated patients, were lung and breast cancer, followed by gastric, colorectal, renal cell, prostate cancer, lymphoma, and malignant melanoma [see Warnings and Precautions (5.3) ]. Laboratory Abnormalities Lymphopenia : In the placebo-controlled clinical trials in patients with RA, confirmed decreases in absolute lymphocyte counts below 500 cells/mm 3 occurred in 0.04% of patients for the tofacitinib 5 mg twice daily and 10 mg twice daily groups combined during the first 3 months of exposure. Confirmed lymphocyte counts less than 500 cells/mm 3 were associated with an increased incidence of treated and serious infections [see Warnings and Precautions (5.9) ]. Neutropenia : In the placebo-controlled clinical trials in patients with RA, confirmed decreases in ANC below 1,000 cells/mm 3 occurred in 0.07% of patients for the tofacitinib 5 mg twice daily and 10 mg twice daily groups combined during the first 3 months of exposure. There were no confirmed decreases in ANC below 500 cells/mm 3 observed in any treatment group. There was no clear relationship between neutropenia and the occurrence of serious infections. In the long-term safety population, the pattern and incidence of confirmed decreases in ANC remained consistent with what was seen in the placebo-controlled clinical trials [see Warnings and Precautions (5.9) ]. Liver Enzyme Elevations : Confirmed increases in liver enzymes greater than 3 times the upper limit of normal (3x ULN) were observed in patients with RA treated with tofacitinib. In patients experiencing liver enzyme elevation, modification of treatment regimen, such as reduction in the dose of concomitant DMARD, interruption of tofacitinib, or reduction in tofacitinib dosage, resulted in decrease or normalization of liver enzymes. In the placebo-controlled monotherapy trials (0-3 months), no differences in the incidence of ALT or AST elevations were observed between the placebo, and tofacitinib 5 mg, and 10 mg twice daily groups. In the placebo-controlled background DMARD trials (0-3 months), ALT elevations greater than 3x ULN were observed in 1.0%, 1.3% and 1.2% of patients who received placebo, tofacitinib 5 mg, and 10 mg twice daily, respectively. In these trials, AST elevations greater than 3x ULN were observed in 0.6%, 0.5% and 0.4% of patients who received placebo, tofacitinib 5 mg, and 10 mg twice daily, respectively. One case of drug-induced liver injury was reported in a patient treated with tofacitinib 10 mg twice daily for approximately 2.5 months. The patient developed symptomatic elevations of AST and ALT greater than 3x ULN and bilirubin elevations greater than 2x ULN, which required hospitalizations and a liver biopsy. Lipid Elevations : In the placebo-controlled clinical trials in patients with RA, dose-related elevations in lipid parameters (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides) were observed at one month of exposure and remained stable thereafter. Changes in lipid parameters during the first 3 months of exposure in the placebo-controlled clinical trials are summarized below: Mean LDL cholesterol increased by 15% in the tofacitinib 5 mg twice daily arm and 19% in the tofacitinib 10 mg twice daily arm. Mean HDL cholesterol increased by 10% in the tofacitinib 5 mg twice daily arm and 12% in the tofacitinib 10 mg twice daily arm. Mean LDL/HDL ratios were essentially unchanged in tofacitinib-treated patients. In a placebo-controlled clinical trial, elevations in LDL cholesterol and ApoB decreased to pretreatment levels in response to statin therapy. In the long-term safety population, elevations in lipid parameters remained consistent with what was seen in the placebo-controlled clinical trials. Serum Creatinine Elevations: In the placebo-controlled clinical trials in patients with RA, dose-related elevations in serum creatinine were observed with tofacitinib treatment. The mean increase in serum creatinine was <0.1 mg/dL in the 12-month pooled safety analysis; however, with increasing duration of exposure in the long-term extensions, up to 2% of patients were discontinued from tofacitinib treatment due to the protocol-specified discontinuation criterion of an increase in creatinine by more than 50% of baseline. The clinical significance of the observed serum creatinine elevations is unknown. Common Adverse Reactions Table 4 displays adverse reactions that occurred in 2% or more of patients on tofacitinib 5 mg or 10 mg twice daily and at least 1% greater than in tofacitinib-treated patients that observed in placebo-treated patients with or without DMARD in the RA trials. N reflects randomized and treated patients from the seven placebo-controlled clinical trials. * reported in ≥2% of patients treated with either dose of tofacitinib and ≥1% greater than that reported for placebo. ** The recommended dose of tofacitinib for the treatment of RA is 5 mg twice daily [see Dosage and Administration (2) ]. Other adverse reactions that occurred in placebo-controlled and open-label extension studies in patients with RA included: Blood and lymphatic system disorders: Anemia Infections and infestations : Diverticulitis Metabolism and nutrition disorders : Dehydration Psychiatric disorders : Insomnia Nervous system disorders: Paresthesia Respiratory, thoracic and mediastinal disorders : Dyspnea, cough, sinus congestion, interstitial lung disease (cases were limited to patients with RA and some were fatal) Gastrointestinal disorders : Abdominal pain, dyspepsia, vomiting, gastritis, nausea Hepatobiliary disorders : Hepatic steatosis Skin and subcutaneous tissue disorders : Rash, erythema, pruritus Musculoskeletal, connective tissue and bone disorders : Musculoskeletal pain, arthralgia, tendonitis, joint swelling Neoplasms benign, malignant and unspecified (including cysts and polyps) : Non-melanoma skin cancers General disorders and administration site conditions : Pyrexia, fatigue, peripheral edema Clinical Experience in Methotrexate-Naïve Patients Study RA-VI was an active-controlled clinical trial in methotrexate-naïve patients [see Clinical Studies (14) ] . The safety experience in these patients was consistent with Studies RA-I through V. Adverse Reactions in Adults with Psoriatic Arthritis The safety of tofacitinib was evaluated in 2 double-blind Phase 3 clinical trials in adults with active psoriatic arthritis (PsA): Study PsA-I (NCT01877668) had a duration of 12 months and enrolled adults who had an inadequate response to a nonbiologic DMARD and who were naïve to treatment with a TNF blocker. Study PsA-I included a 3-month placebo-controlled period and also included adalimumab 40 mg subcutaneously once every 2 weeks for 12 months. Study PsA-II (NCT01882439) had a duration of 6 months and enrolled adults who had an inadequate response to at least one approved TNF blocker. This clinical trial included a 3-month placebo-controlled period. In these combined Phase 3 clinical trials, 238 patients were randomized and treated with tofacitinib 5 mg twice daily and 236 patients were randomized and treated with tofacitinib 10 mg twice daily. A dosage of tofacitinib 10 mg twice daily is not recommended for the treatment of PsA. For the treatment of adults with active PsA [see Indications and Usage (1.2) ] , the recommended dosage of tofacitinib is 5 mg twice daily and the recommended dosage for tofacitinib extended-release tablets is 11 mg once daily [see Dosage and Administration (2.3) ]. All patients in the clinical trials in patients with PsA were required to receive treatment with a stable dose of a nonbiologic DMARD [the majority (79%) received methotrexate]. The study population randomized and treated with tofacitinib (474 patients) included 45 (10%) patients aged 65 years or older and 66 (14%) patients with diabetes at baseline. During the 2 PsA controlled clinical trials, there were: 3 malignancies (excluding NMSC) in 474 patients who received tofacitinib plus non-biologic DMARD (6 to 12 months exposure) 0 malignancies in 236 patients who received placebo plus non-biologic DMARD group (3 months exposure) and 0 malignancies in 106 patients in patients who received adalimumab plus non-biologic DMARD group (12 months exposure). No lymphomas were reported. Malignancies have also been observed in the long-term extension study in patients with PsA treated with tofacitinib. The safety profile observed in adults with active PsA treated with tofacitinib was consistent with the safety profile observed in adults with RA. Adverse Reactions in Adults with Ankylosing Spondylitis The safety of tofacitinib was evaluated in adults with active ankylosing spondylitis (AS) in a double-blind placebo-controlled Phase 3 clinical trial (Study AS-I) and in a dose-ranging Phase 2 clinical trial (Study AS-II). Study AS-I (NCT03502616) had a duration of 48 weeks and enrolled adults who had an inadequate response to at least 2 NSAIDs. Study AS-I included a 16-week double-blind period in which patients received tofacitinib 5 mg or placebo twice daily and a 32-week open-label treatment period in which all patients received tofacitinib 5 mg twice daily. Study AS-II (NCT01786668) had a duration of 16 weeks and enrolled adults who had an inadequate response to at least 2 NSAIDs. This clinical trial included a 12-week treatment period in which patients received either tofacitinib 2 mg (40% of the recommended dose), 5 mg, 10 mg, or placebo twice daily. A dosage of tofacitinib 10 mg twice daily is not recommended for the treatment of AS. For the treatment of adults with active AS [see Indications and Usage (1.3) ] , the recommended dosage of tofacitinib is 5 mg twice daily and the recommended dosage for tofacitinib extended-release tablets is 11 mg once daily [see Dosage and Administration (2.3) ]. In the combined Phase 2 and Phase 3 clinical trials, a total of 420 patients were treated with either tofacitinib 2 mg, 5 mg, or 10 mg twice daily. Of these, 316 patients were treated with tofacitinib 5 mg twice daily for up to 48 weeks. In the combined double-blind period, 185 patients were randomized to and treated with tofacitinib 5 mg twice daily and 187 to placebo for up to 16 weeks. Concomitant treatment with stable doses of nonbiologic DMARDs, NSAIDs, or corticosteroids (≤10 mg/day) was permitted. The study population randomized and treated with tofacitinib included 13 (3%) patients aged 65 years or older and 18 (4%) patients with diabetes at baseline. The safety profile observed in adults with AS treated with tofacitinib was consistent with the safety profile observed in adults with RA and PsA. Adverse Reactions in Adults with Ulcerative Colitis The safety of tofacitinib has been evaluated in adults with moderately to severely active UC in 4 randomized, double-blind, placebo-controlled trials (UC-I, UC-II, UC-III, and dose-ranging UC-V) and an open-label long-term extension study (UC-IV) [see Clinical Studies (14.4) ]. Adverse reactions reported in ≥5% of patients treated with either tofacitinib 5 mg or 10 mg twice daily and ≥1% greater than reported in patients receiving placebo in either the induction or maintenance clinical trials of patients with UC were: nasopharyngitis, elevated cholesterol levels, headache, upper respiratory tract infection, increased blood creatine phosphokinase, rash, diarrhea, and herpes zoster. Induction Trials in Adults with UC Common adverse reactions reported in ≥2% of patients treated with tofacitinib 10 mg twice daily and ≥1% greater in tofacitinib -treated patients than placebo-treated patients in the 3 induction trials of patients with UC (Studies UC-I, UC-II, and UC-V) were: headache, nasopharyngitis, elevated cholesterol levels, acne, increased blood creatine phosphokinase, and pyrexia. Maintenance Trial in Adults with UC Common adverse reactions reported in ≥4% of patients treated with either dosage of tofacitinib and ≥1% greater than reported in patients treated with placebo in the maintenance trial of patients with UC (Study UC-III) are shown in Table 5. Dose-dependent adverse reactions seen in patients treated with tofacitinib 10 mg twice daily, in comparison to 5 mg twice daily, include the following: herpes zoster infections, serious infections, and NMSC [see Warnings and Precautions (5.1 , 5.3) ]. During the UC controlled clinical studies (8-week induction and 52-week maintenance studies), which included 1,220 patients, 0 cases of solid cancer or lymphoma were observed in tofacitinib-treated patients. In the long-term extension study, malignancies (including solid cancers, lymphomas and NMSC) were observed in patients treated with tofacitinib 5 mg and 10 mg twice daily [see Warnings and Precautions (5.3) ] . Five cases of pulmonary embolism were reported in patients taking tofacitinib 10 mg twice daily, including one fatality in a patient with advanced cancer [see Warnings and Precautions (5.5) ]. 1 1 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of tofacitinib. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.

( 8.2 ) 8.1 Pregnancy Risk Summary The available data with tofacitinib from a pregnancy exposure registry that enrolled 11 exposed pregnant females, pharmacovigilance, and published literature are insufficient to draw conclusions about a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with RA and UC in pregnancy (see Clinical Considerations ) . In animal reproduction studies, fetocidal and teratogenic effects were noted when pregnant rats and rabbits received tofacitinib during the period of organogenesis at exposures multiples of 73-times and 6.3-times the maximum recommended dose of 10 mg twice daily, respectively. Further, in a peri- and post-­ natal study in rats, tofacitinib resulted in reductions in live litter size, postnatal survival, and pup body weights at exposure multiples of approximately 73-times the recommended dosage of 5 mg twice daily and approximately 36 times the maximum recommended dosage of 10 mg twice daily, respectively (see Data ) . The background risks of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risks in the U.S. general population of major birth defects and miscarriages are 2 to 4% and 15 to 20% of clinically recognized pregnancies, respectively. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk: Published data suggest that increased disease activity is associated with the risk of developing adverse pregnancy outcomes in women with RA or UC. Adverse pregnancy outcomes include preterm delivery (before 37 weeks of gestation), low birth weight (less than 2500 grams) infants, and small for gestational age at birth. Data Animal Data: In a rat embryofetal developmental study, in which pregnant rats received tofacitinib during organogenesis, tofacitinib was teratogenic at exposure levels approximately 146 times the recommended dose of 5 mg twice daily, and approximately 73 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 100 mg/kg/day in rats). Teratogenic effects consisted of external and soft tissue malformations of anasarca and membranous ventricular septal defects, respectively; and skeletal malformations or variations (absent cervical arch; bent femur, fibula, humerus, radius, scapula, tibia, and ulna; sternoschisis; absent rib; misshapen femur; branched rib; fused rib; fused sternebra; and hemicentric thoracic centrum). In addition, there was an increase in post-implantation loss, consisting of early and late resorptions, resulting in a reduced number of viable fetuses. Mean fetal body weight was reduced. No developmental toxicity was observed in rats at exposure levels approximately 58 times the recommended dose of 5 mg twice daily, and approximately 29 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in pregnant rats). In a rabbit embryofetal developmental study in which pregnant rabbits received tofacitinib during the period of organogenesis, tofacitinib was teratogenic at exposure levels approximately 13 times the recommended dose of 5 mg twice daily, and approximately 6.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 30 mg/kg/day in rabbits) in the absence of signs of maternal toxicity. Teratogenic effects included thoracogastroschisis, omphalocele, membranous ventricular septal defects, and cranial/skeletal malformations (microstomia, microphthalmia), mid-line and tail defects. In addition, there was an increase in post-implantation loss associated with late resorptions. No developmental toxicity was observed in rabbits at exposure levels approximately 3 times the recommended dose of 5 mg twice daily, and approximately 1.5 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 10 mg/kg/day in pregnant rabbits). In a peri- and postnatal development study in pregnant rats that received tofacitinib from gestation day 6 through day 20 of lactation, there were reductions in live litter size, postnatal survival, and pup body weights at exposure levels approximately 73 times the recommended dose of 5 mg twice daily, and approximately 36 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 50 mg/kg/day in rats). There was no effect on behavioral and learning assessments, sexual maturation or the ability of the F1 generation rats to mate and produce viable F2 generation fetuses in rats at exposure levels approximately 17 times the recommended dose of 5 mg twice daily, and approximately 8.3 times the maximum recommended dose of 10 mg twice daily (on an AUC basis at oral doses of 10 mg/kg/day in rats). 8.2 Lactation Risk Summary Based on published data, tofacitinib is present in human milk. Data on the effects of tofacitinib on the breastfed infant is limited to a small number of cases with no reported adverse effects. There are no data on the effects on milk production. Given the serious adverse reactions seen in patients treated with tofacitinib, such as increased risk of serious infections, advise patients that breastfeeding is not recommended during treatment and for at least 36 hours after the last dose of tofacitinib extended-release tablets (approximately 6 elimination half-lives). Data Following administration of tofacitinib to lactating rats, concentrations of tofacitinib in milk over time paralleled those in serum and were approximately 2 times higher in milk relative to maternal serum at all time points measured. 8.3 Females and Males of Reproductive Potential Contraception Females In an animal reproduction study, tofacitinib at AUC multiples of 13 times the recommended dosage of 5 mg twice daily and 6.3 times the maximum recommended dosage of 10 mg twice daily demonstrated adverse embryo-fetal findings [see Use in Specific Populations (8.1) ] . However, there is uncertainty as to how these animal findings relate to females of reproductive potential treated with the recommended clinical dosage. Consider pregnancy planning and prevention for females of reproductive potential. Infertility Females Based on findings in rats, treatment with tofacitinib may result in reduced fertility in females of reproductive potential. It is not known if this effect is reversible [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use The safety and effectiveness of tofacitinib extended-release tablets in pediatric patients have not been established. 8.5 Geriatric Use Of the 3315 adults who were enrolled in clinical trials with RA (Studies RA-I to V), a total of 505 patients were 65 years of age and older, including 71 patients 75 years and older. The frequency of serious infection among tofacitinib tablets-treated patients 65 years of age and older was higher than among those adults under the age of 65. Of the 1156 tofacitinib tablet-treated patients in clinical trials of patients with UC, a total of 77 patients (7%) were 65 years of age or older. Clinical studies of tofacitinib in patients with UC did not include sufficient numbers of patients aged 65 years and older to determine whether they respond differently from younger adult patients. Of the 783 tofacitinib tablet-treated patients in clinical trials of patients with PsA, a total of 72 (9.2%) patients were 65 years of age and older, including 2 (0.3%) patients 75 years and older. These clinical studies did not include sufficient numbers of patients aged 65 years and older with PsA to determine if they respond differently from younger adult patients. Of the 420 tofacitinib tablet-treated patients in clinical trials of patients with AS, a total of 12 (2.9%) patients were 65 years of age and older, including 1 (0.2%) patient 75 years and older. These clinical studies did not include sufficient numbers of patients aged 65 years and older with AS to determine if they respond differently from younger adult patients. 8.6 Renal Impairment Moderate and Severe Renal Impairment Tofacitinib-treated patients with moderate renal impairment (RI) (CLcr ≥30 and ≤50 mL/minute) or severe RI (<30 mL/minute) had greater tofacitinib blood concentrations than tofacitinib-treated patients with normal renal function (CLcr >80 mL/minute). The recommended dosage of tofacitinib in patients with moderate or severe RI (including those with severe RI who are undergoing hemodialysis) is lower than the recommended dosage in patients with normal renal function [see Dosage and Administration (2.3, 2.4) ]. Mild Renal Impairment The recommended dosage in patients with mild RI (CLcr >50 and ≤80 mL/minute) is the same as patients with normal renal function. 8.7 Hepatic Impairment Severe Hepatic Impairment Tofacitinib has not been studied in patients with severe hepatic impairment (HI) (Child-Pugh C); therefore, use of tofacitinib in patients with severe HI is not recommended. Moderate Hepatic Impairment Tofacitinib-treated patients with moderate hepatic impairment (Child-Pugh B) had greater tofacitinib blood concentration than tofacitinib-treated patients with normal hepatic function [see Clinical Pharmacology (12.3) ] . Higher blood concentrations may increase the risk of some adverse reactions. The recommended tofacitinib dosage in patients with moderate HI is lower than the recommended dosage in patients with normal hepatic function [see Dosage and Administration (2.3, 2.4) ]. Mild Hepatic Impairment The recommended dosage of tofacitinib in patients with mild hepatic impairment (Child-Pugh A) is the same as patients with normal hepatic function. Hepatitis B or C Serology The safety and efficacy of tofacitinib have not been studied in patients with positive hepatitis B virus or hepatitis C virus serology." ], "pregnancy": [ "8.1 Pregnancy Risk Summary The available data with tofacitinib from a pregnancy exposure registry that enrolled 11 exposed pregnant females, pharmacovigilance, and published literature are insufficient to draw conclusions about a drug-associated risk of major birth defects, miscarriage, or other adverse maternal or fetal outcomes. There are risks to the mother and the fetus associated with RA and UC in pregnancy (see Clinical Considerations ) . In animal reproduction studies, fetocidal and teratogenic effects were noted when pregnant rats and rabbits received tofacitinib during the period of organogenesis at exposures multiples of 73-times and 6.3-times the maximum recommended dose of 10 mg twice daily, respectively. Further, in a peri- and post-­ natal study in rats, tofacitinib resulted in reductions in live litter size, postnatal survival, and pup body weights at exposure multiples of approximately 73-times the recommended dosage of 5 mg twice daily and approximately 36 times the maximum recommended dosage of 10 mg twice daily, respectively (see Data ) . The background risks of major birth defects and miscarriage for the indicated populations are unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. The background risks in the U.S. general population of major birth defects and miscarriages are 2 to 4% and 15 to 20% of clinically recognized pregnancies, respectively.

JAKs are intracellular enzymes which transmit signals arising from cytokine or growth factor-receptor interactions on the cellular membrane to influence cellular processes of hematopoiesis and immune cell function. Within the signaling pathway, JAKs phosphorylate and activate Signal Transducers and Activators of Transcription (STATs) which modulate intracellular activity including gene expression. Tofacitinib modulates the signaling pathway at the point of JAKs, preventing the phosphorylation and activation of STATs. JAK enzymes transmit cytokine signaling through pairing of JAKs (e.g., JAK1/JAK3, JAK1/JAK2, JAK1/TyK2, JAK2/JAK2). Tofacitinib inhibited the in vitro activities of JAK1/JAK2, JAK1/JAK3, and JAK2/JAK2 combinations with IC 50 of 406, 56, and 1377 nM, respectively. However, the relevance of specific JAK combinations to therapeutic effectiveness is not known. 12.2 Pharmacodynamics Treatment with tofacitinib was associated with dose-dependent reductions of circulating CD16/56+ natural killer cells, with estimated maximum reductions occurring at approximately 8-10 weeks after initiation of therapy. These changes generally resolved within 2-6 weeks after discontinuation of treatment. Treatment with tofacitinib was associated with dose-dependent increases in B cell counts. Changes in circulating T-lymphocyte counts and T-lymphocyte subsets (CD3+, CD4+ and CD8+) were small and inconsistent. The clinical significance of these changes is unknown. Total serum IgG, IgM, and IgA levels after 6-month dosing in patients with rheumatoid arthritis (RA) were lower than in patients who received placebo; however, changes were small and not dose-dependent. After treatment with tofacitinib in patients with RA, rapid decreases in serum C-reactive protein (CRP) were observed and maintained throughout dosing. Changes in CRP observed with tofacitinib treatment do not reverse fully within 2 weeks after discontinuation, indicating a longer duration of pharmacodynamic activity compared to the pharmacokinetic half-life. Similar changes in T cells, B cells, and serum CRP have been observed in patients with active psoriatic arthritis (PsA) although reversibility was not assessed. Total serum immunoglobulins were not assessed in patients with active PsA. 12.3 Pharmacokinetics Following oral administration of tofacitinib, peak plasma concentrations were reached within 0.5 hour - 1 hour, elimination half-life was about 3 hours and a dose-proportional increase in systemic exposure was observed in the therapeutic dosage range. Steady state concentrations were achieved in 24-48 hours with negligible accumulation after twice daily administration. Following oral administration of tofacitinib extended-release tablets, peak plasma concentrations were reached at 4 hours and half-life was about 6 to 8 hours. Steady state concentrations were achieved within 48 hours with negligible accumulation after once daily administration. Table 7 describes the pharmacokinetic parameters of tofacitinib and tofacitinib extended-release tablets. Absorption Tofacitinib The absolute oral bioavailability of tofacitinib is 74%. Coadministration of tofacitinib with a high-fat meal resulted in no changes in AUC while Cmax was reduced by 32%. In clinical trials, tofacitinib was administered without regard to meals [see Dosage and Administration (2.2) ]. Tofacitinib Extended-Release Tablets Coadministration of tofacitinib extended-release tablets 11 and 22 mg with a high-fat meal resulted in no changes in AUC while Cmax was increased by 27% and 19% respectively. T max was extended by approximately 1 hour for both tofacitinib extended-release tablets 11 and 22 mg. Distribution After intravenous administration, the volume of distribution was 87 L. The protein binding of tofacitinib is approximately 40%. Tofacitinib binds predominantly to albumin and does not appear to bind to α1-acid glycoprotein. Tofacitinib distributes equally between red blood cells and plasma. Metabolism and Excretion Clearance mechanisms for tofacitinib are approximately 70% hepatic metabolism and 30% renal excretion of the parent drug. The metabolism of tofacitinib is primarily mediated by CYP3A4 with minor contribution from CYP2C19. In a human radiolabeled study, more than 65% of the total circulating radioactivity was accounted for by unchanged tofacitinib, with the remaining 35% attributed to 8 metabolites, each accounting for less than 8% of total radioactivity. The pharmacologic activity of tofacitinib is attributed to the parent molecule. Pharmacokinetics in Patients with RA, PsA, AS, and UC Population pharmacokinetic (PK) analyses indicated that PK characteristics were similar between patients with RA, PsA, ankylosing spondylitis, and UC. The coefficient of variation (%) in AUC of tofacitinib were generally similar across different disease patients, ranging from 22% to 34% (Table 8). Specific Populations Covariate evaluation as part of population PK analyses in adult patient populations indicated no clinically relevant change in tofacitinib exposure, after accounting for differences in renal function (i.e., creatinine clearance) between patients, based on age, weight, biological sex and race (Figure 1). An approximately linear relationship between body weight and volume of distribution was observed, resulting in higher peak (C max ) and lower trough (C min ) concentrations in lighter patients. However, this difference is not considered to be clinically relevant. The effect of renal and hepatic impairment and other intrinsic factors on the PK of tofacitinib is shown in Figure 1. Note: Reference values for weight, age, biological sex, and race comparisons are 70 kg, 55 years, male, and white, respectively; reference groups for renal and hepatic impairment data are patients with normal renal and hepatic function. Renal function was estimated using creatinine clearance by Cockcroft-Gault method and hepatic function was estimated using Child-Pugh scoring method. In patients with end-stage renal disease maintained on hemodialysis, mean AUC was approximately 40% higher compared with historical healthy subject data, consistent with approximately 30% contribution of renal clearance to the total clearance of tofacitinib [see Dosage and Administration (2.3, 2.4) and Use in Specific Populations (8.6) ]. Drug Interaction Studies Potential for Tofacitinib to Influence the PK of Other Drugs In vitro studies indicate that tofacitinib does not significantly inhibit or induce the activity of the major human drug-metabolizing CYPs (CYP1A2, CYP2B6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, and CYP3A4) at concentrations corresponding to the steady state C max of a 10 mg twice daily dose. These in vitro results were confirmed by a human drug interaction study showing no changes in the pharmacokinetics of midazolam, a highly sensitive CYP3A4 substrate, when concomitantly administered with tofacitinib. In vitro studies indicate that tofacitinib does not significantly inhibit the activity of the major human drug-metabolizing uridine 5'-diphospho-glucuronosyltransferases (UGTs) [UGT1A1, UGT1A4, UGT1A6, UGT1A9, and UGT2B7] at concentrations exceeding 250 times the steady state C max of a 10 mg twice daily dose. In patients with RA, the oral clearance of tofacitinib does not vary with time, indicating that tofacitinib does not normalize CYP enzyme activity in patients with RA. Therefore, concomitant use with tofacitinib tablets/tofacitinib extended-release tablets is not expected to result in clinically relevant increases in the metabolism of CYP substrates in patients with RA. In vitro data indicate that the potential for tofacitinib to inhibit transporters such as P-glycoprotein, organic anionic or cationic transporters at therapeutic concentrations is low. The impact of tofacitinib on the PK of other drugs for the concomitant drugs are shown in Figure 2. Note: Reference group is administration of concomitant medication alone; OCT = Organic Cationic Transporter; MATE = Multidrug and Toxic Compound Extrusion. Potential for Other Drugs to Influence the Pharmacokinetics of Tofacitinib Since tofacitinib is metabolized by CYP3A4, interaction with drugs that inhibit or induce CYP3A4 is likely. Inhibitors of CYP2C19 alone or P-glycoprotein are unlikely to substantially alter the pharmacokinetics of tofacitinib (see Figure 3).

In vitro studies indicate that tofacitinib does not significantly inhibit the activity of the major human drug-metabolizing uridine 5'-diphospho-glucuronosyltransferases (UGTs) [UGT1A1, UGT1A4, UGT1A6, UGT1A9, and UGT2B7] at concentrations exceeding 250 times the steady state C max of a 10 mg twice daily dose. In patients with RA, the oral clearance of tofacitinib does not vary with time, indicating that tofacitinib does not normalize CYP enzyme activity in patients with RA. Therefore, concomitant use with tofacitinib tablets/tofacitinib extended-release tablets is not expected to result in clinically relevant increases in the metabolism of CYP substrates in patients with RA. In vitro data indicate that the potential for tofacitinib to inhibit transporters such as P-glycoprotein, organic anionic or cationic transporters at therapeutic concentrations is low. The impact of tofacitinib on the PK of other drugs for the concomitant drugs are shown in Figure 2. Note: Reference group is administration of concomitant medication alone; OCT = Organic Cationic Transporter; MATE = Multidrug and Toxic Compound Extrusion. Potential for Other Drugs to Influence the Pharmacokinetics of Tofacitinib Since tofacitinib is metabolized by CYP3A4, interaction with drugs that inhibit or induce CYP3A4 is likely. Inhibitors of CYP2C19 alone or P-glycoprotein are unlikely to substantially alter the pharmacokinetics of tofacitinib (see Figure 3). Note: Reference group is administration of tofacitinib alone. 1 1 1 1 1" ], "nonclinical_toxicology": [ "13 NONCLINICAL TOXICOLOGY 13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility In a 39-week toxicology study in monkeys, tofacitinib at exposure levels approximately 6 times the recommended dose of 5 mg twice daily, and approximately 3 times the 10 mg twice daily dose (on an AUC basis at oral doses of 5 mg/kg twice daily) produced lymphomas. No lymphomas were observed in this study at exposure levels 1 times the recommended dose of 5 mg twice daily, and approximately 0.5 times the 10 mg twice daily dose (on an AUC basis at oral doses of 1 mg/kg twice daily).

The relevance of benign Leydig cell tumors to human risk is not known. Tofacitinib was not mutagenic in the bacterial reverse mutation assay. It was positive for clastogenicity in the in vitro chromosome aberration assay with human lymphocytes in the presence of metabolic enzymes, but negative in the absence of metabolic enzymes. Tofacitinib was negative in the in vivo rat micronucleus assay and in the in vitro CHO-HGPRT assay and the in vivo rat hepatocyte unscheduled DNA synthesis assay. In rats, tofacitinib at exposure levels approximately 17 times the recommended dose of 5 mg twice daily, and approximately 8.3 times the 10 mg twice daily dose (on an AUC basis at oral doses of 10 mg/kg/day) reduced female fertility due to increased post-implantation loss.

Trial Design Study RA-I (NCT00814307) was a 6-month monotherapy trial in which 610 patients with moderate to severe active RA who had an inadequate response to a DMARD (nonbiologic or biologic) received tofacitinib 5 mg or 10 mg twice daily or placebo added to their background DMARD. At the Month 3 visit, all patients randomized to placebo treatment were switched in a blinded fashion to a second predetermined treatment of tofacitinib 5 mg or 10 mg twice daily. The primary endpoints at Month 3 were the proportion of patients who achieved an ACR20 response, changes in Health Assessment Questionnaire – Disability Index (HAQ-DI), and rates of Disease Activity Score DAS28-4(ESR) less than 2.6. Study RA-II (NCT00856544) was a 12-month trial in which 792 patients with moderate to severe active RA who had an inadequate response to a nonbiologic DMARD received tofacitinib 5 mg or 10 mg twice daily or placebo added to background DMARD treatment (excluding potent immunosuppressive treatments such as azathioprine or cyclosporine). At the Month 3 visit, nonresponding patients were switched in a blinded fashion to a second predetermined treatment of tofacitinib 5 mg or 10 mg twice daily. At the end of Month 6, all patients treated with placebo were switched to their second predetermined tofacitinib treatment in a blinded fashion. The primary endpoints were the proportion of patients who achieved an ACR20 response at Month 6, changes in HAQ-DI at Month 3, and rates of DAS28-4(ESR) less than 2.6 at Month 6. Study RA-III (NCT00853385) was a 12-month trial in 717 patients with moderate to severe active RA who had an inadequate response to methotrexate (MTX). Patients received tofacitinib 5 mg or 10 mg orally twice daily, adalimumab 40 mg subcutaneously every other week, or placebo added to background MTX. Patients treated with placebo were switched as in Study RA-II. The primary endpoints were the proportion of patients who achieved an ACR20 response at Month 6, HAQ-DI at Month 3, and DAS28-4(ESR) less than 2.6 at Month 6. Study RA-IV (NCT00847613) was a 2-year trial with a planned analysis at 1 year in which 797 patients with moderate to severe active RA who had an inadequate response to MTX received tofacitinib 5 mg or 10 mg twice daily or placebo added to background MTX. Patients treated with placebo were switched as in Study RA-II. The primary endpoints were the proportion of patients who achieved an ACR20 response at Month 6, mean change from baseline in van der Heijde-modified total Sharp Score (mTSS) at Month 6, HAQ-DI at Month 3, and DAS28-4(ESR) less than 2.6 at Month 6. Study RA-V (NCT00960440) was a 6-month trial in which 399 patients with moderate to severe active RA who had an inadequate response to at least one approved TNF blocking biological product received tofacitinib 5 mg or 10 mg twice daily or placebo added to background MTX. At the Month 3 visit, all patients randomized to placebo treatment were switched in a blinded fashion to a second predetermined treatment of tofacitinib 5 or 10 mg twice daily. The primary endpoints at Month 3 were the proportion of patients who achieved an ACR20 response, HAQ-DI, and DAS28-4(ESR) less than 2.6. Study RA-VI (NCT01039688) was a 2-year monotherapy trial with a planned analysis at 1 year in which 952 MTX-naïve patients with moderate to severe active RA received tofacitinib 5 or 10 mg twice daily or MTX dose-titrated over 8 weeks to 20 mg weekly. The primary endpoints were mean change from baseline in van der Heijde-modified Total Sharp Score (mTSS) at Month 6 and the proportion of patients who achieved an ACR70 response at Month 6. Although other dosages have been studied, the recommended dosage of tofacitinib is 5 mg twice daily. Tofacitinib 10 mg twice daily is not recommended for the treatment of RA [see Dosage and Administration (2.3) ]. Clinical Response The percentages of tofacitinib-treated patients who achieved ACR20, ACR50, and ACR70 responses in Studies RA-I, IV, and V are shown in Table 9. Similar results were observed with Studies RA-II and III. In trials RA-I through V, patients treated with 5 mg twice daily tofacitinib had higher ACR20, ACR50, and ACR70 response rates versus patients treated with placebo, with or without background DMARD treatment, at Month 3 and Month 6. Higher ACR20 response rates were observed within 2 weeks compared to placebo. In the 12-month trials, ACR response rates in tofacitinib-treated patients were consistent at 6 and 12 months. In Study RA-IV, a greater proportion of patients treated with tofacitinib 5 mg twice daily plus MTX achieved a low level of disease activity as measured by a DAS28-4(ESR) less than 2.6 at 6 months compared to those treated with MTX alone (Table 10). The results of the components of the ACR response criteria for Study RA-IV are shown in Table 11. Similar results were observed for tofacitinib in Studies RA-I, II, III, V, and VI. The percent of ACR20 responders by visit for Study RA-IV is shown in Figure 4. Similar responses were observed for tofacitinib in Studies RA-I, II, III, V, and VI. Radiographic Response Two studies were conducted to evaluate the effect of tofacitinib on structural joint damage. In Study RA-IV and Study RA-VI, progression of structural joint damage was assessed radiographically and expressed as change from baseline in mTSS and its components, the erosion score and joint space narrowing score, at Months 6 and 12. The proportion of patients with no radiographic progression (mTSS change less than or equal to 0) was also assessed. In Study RA-IV, tofacitinib 5 mg twice daily reduced the mean progression of structural damage (not statistically significant) as shown in Table 12. Analyses of erosion and joint space narrowing scores were consistent with the overall results. In the placebo plus MTX group, 74% of patients experienced no radiographic progression at Month 6 compared to 84% of patients treated with tofacitinib plus MTX 5 mg twice daily. In Study RA-VI, tofacitinib monotherapy inhibited the progression of structural damage compared to MTX at Months 6 and 12 as shown in Table 12. Analyses of erosion and joint space narrowing scores were consistent with the overall results. In the MTX group, 55% of patients experienced no radiographic progression at Month 6 compared to 73% of patients treated with tofacitinib 5 mg twice daily. Physical Function Response Improvement in physical functioning was measured by the HAQ-DI. Patients who received tofacitinib 5 mg twice daily demonstrated greater improvement from baseline in physical functioning compared to patients who received placebo at Month 3. The mean (95% CI) difference from placebo in HAQ-DI improvement from baseline at Month 3 in Study RA-III was -0.22 (-0.35, -0.10) in patients who received 5 mg tofacitinib twice daily. Similar results were obtained in Studies RA-I, II, IV and V. In the 12-month trials, HAQ-DI results in tofacitinib-treated patients were consistent at 6 and 12 months. Other Health-Related Outcomes General health status was assessed by the Short Form health survey (SF-36). In Studies RA-I, IV, and V, patients who received tofacitinib 5 mg twice daily demonstrated greater improvement from baseline compared to placebo in physical component summary (PCS), mental component summary (MCS) scores and in all 8 domains of the SF-36 at Month 3. 1 1 1 1 1 14.2 Clinical Studies in Psoriatic Arthritis The psoriatic arthritis (PsA) clinical development program with tofacitinib tablets included 2 multicenter, randomized, double-blind, placebo-controlled trials in 816 adults with active PsA (Studies PsA-I and PsA-II). Trial Designs and Population All patients had active PsA for at least 6 months based upon the Classification Criteria for Psoriatic Arthritis (CASPAR), at least 3 tender/painful joints and at least 3 swollen joints, and active plaque psoriasis. Patients randomized and treated across the 2 clinical trials represented different PsA subtypes at screening, including <5 joints or asymmetric involvement (21%),≥5 joints involved (90%), distal interphalangeal (DIP) joint involvement (61%), arthritis mutilans (8%), and spondylitis (19%). Patients in these clinical trials had a diagnosis of PsA for a mean (SD) of 7.7 (7.2) years. At baseline, 80% and 53% of patients had enthesitis and dactylitis, respectively. At baseline, all patients were required to receive treatment with a stable dose of a nonbiologic DMARD (79% received methotrexate, 13% received sulfasalazine, 7% received leflunomide, 1% received other nonbiologic DMARDs). In both clinical trials, the primary endpoints were the ACR20 response and the change from baseline in HAQ-DI at Month 3. Study PsA-I was a 12-month clinical trial in 422 patients who had an inadequate response to a nonbiologic DMARD (67% and 33% were inadequate responders to 1 nonbiologic DMARD and ≥2 nonbiologic DMARDs, respectively) and who were naïve to treatment with a TNF blocker. Although Study PsA-1 included patients who are TNF blocker- naïve, tofacitinib and tofacitinib extended-release tablets are not approved for use in TNF blocker-naïve patients [see Indications and Usage (1.2) ] . Patients were randomized in a 2:2:2:1:1 ratio to receive tofacitinib 5 mg twice daily, tofacitinib 10 mg twice daily, adalimumab 40 mg subcutaneously once every 2 weeks, placebo to tofacitinib 5 mg twice daily treatment sequence, or placebo to tofacitinib 10 mg twice daily treatment sequence, respectively; study drug was added to background nonbiologic DMARD treatment. At the Month 3 visit, all patients randomized to placebo treatment were switched in a blinded fashion to a predetermined tofacitinib dosage of 5 mg or 10 mg twice daily. Study PsA-I was not designed to demonstrate non-inferiority or superiority to adalimumab. Study PsA-II was a 6-month clinical trial in 394 patients who had an inadequate response to at least 1 approved TNF blocker (66%, 19%, and 15% were inadequate responders to 1 TNF blocker, 2 TNF blockers and ≥3 TNF blockers, respectively). Patients were randomized in a 2:2:1:1 ratio to receive tofacitinib 5 mg twice daily, tofacitinib 10 mg twice daily, placebo to tofacitinib 5 mg twice daily treatment sequence, or placebo to tofacitinib 10 mg twice daily treatment sequence, respectively; study drug was added to background nonbiologic DMARD treatment. At the Month 3 visit, placebo patients were switched in a blinded fashion to a predetermined tofacitinib dosage of 5 mg or 10 mg twice daily as in Study PsA-I. Although other dosages have been studied, the recommended dosage of tofacitinib is 5 mg twice daily. Tofacitinib 10 mg twice daily is not recommended for treatment of PsA [see Dosage and Administration (2.3) ]. Clinical Response At Month 3, patients treated with tofacitinib 5 mg twice daily had higher (p≤0.05) response rates versus placebo for ACR20, ACR50, and ACR70 in Study PsA-I and for ACR20 and ACR50 in Study PsA-II; ACR70 response rates were also higher for tofacitinib 5 mg twice daily versus placebo in Study PsA-II, although the differences versus placebo were not statistically significant (p>0.05) (Tables 13 and 14). Patients with missing data were treated as non-responders. * Patients received one concomitant nonbiologic DMARD. ** Tofacitinib and tofacitinib extended-release tablets are not approved for use in TNF blocker-naïve patients [see Indications and Usage (1.2) ]. a N is number of randomized and treated patients.

The percentage of ACR20 responders by visit for Study PsA-I is shown in Figure 5. Similar responses were observed in Study PsA-II. In both studies, improvement in ACR20 response on tofacitinib was observed at the first visit after baseline (Week 2). BID = twice daily; SE = standard error. Patients with missing data were treated as non-responders. * Subjects received one concomitant nonbiologic DMARD. ** Tofacitinib and tofacitinib extended-release tablets are not approved for use in TNF blocker-naïve patients [see Indications and Usage (1.2) ]. In patients with active PsA evidence of benefit in enthesitis and dactylitis was observed with tofacitinib treatment. Physical Function Improvement in physical functioning was measured by the HAQ-DI. Patients receiving tofacitinib 5 mg twice daily demonstrated significantly greater improvement (p ≤0.05) from baseline in physical functioning compared to placebo at Month 3 (Table 16). * Patients received one concomitant nonbiologic DMARD. ** Tofacitinib and tofacitinib extended-release tablets are not approved for use in TNF blocker-naïve patients [see Indications and Usage (1.2) ]. a N is the total number of patients in the statistical analysis. b Inadequate response to at least one nonbiologic DMARD due to lack of efficacy and/or intolerability. c Inadequate response to at least one TNF blocker due to lack of efficacy and/or intolerability. In Study PsA-I, the HAQ-DI responder rate (response defined as having improvement from baseline of ≥0.35) at Month 3 was 53% in patients receiving tofacitinib 5 mg twice daily and 31% in patients receiving placebo. Similar responses were observed in Study PsA-II. Other Health-Related Outcomes General health status was assessed by the Short Form health survey (SF-36). In Studies PsA-I and PsA-II, patients receiving tofacitinib 5 mg twice daily had greater improvement from baseline compared to placebo in Physical Component Summary (PCS) score, but not in Mental Component Summary (MCS) score at Month 3. Patients receiving tofacitinib 5 mg twice daily reported consistently greater improvement relative to placebo in the domains of Physical Functioning, Bodily Pain, Vitality, and Social Functioning, but not in Role-Physical, General Health, Role-Emotional, or Mental Health. Radiographic Response Treatment effect on inhibition of radiographic progression in PsA could not be established from the results of Study PsA-I. 1 1 1 1 1 14.3 Clinical Studies in Ankylosing Spondylitis The ankylosing spondylitis (AS) clinical development program with tofacitinib tablets included one placebo-controlled trial (Study AS-I) in adults with active AS. Patients had active disease as defined by both Bath Ankylosing Spondylitis Disease Activity Index (BASDAI) and back pain score (BASDAI question 2) of greater or equal to 4 despite non-steroidal anti-inflammatory drug (NSAID), corticosteroid or disease modifying anti-rheumatic drug (DMARD) therapy. Trial Design Study AS-I was a randomized, double-blind, placebo-controlled, 48-week clinical trial in 269 adult patients who had an inadequate response (inadequate clinical response or intolerance) to at least 2 NSAIDs. Although Study AS-I included some patients who are TNF blocker-naïve, tofacitinib and tofacitinib extended-release tablets are not approved for use in TNF blocker-naïve patients [see Indications and Usage (1.3) ] . Patients were randomized and treated with tofacitinib 5 mg twice daily or placebo for 16 weeks of blinded treatment and then all received treatment of tofacitinib 5 mg twice daily for additional 32 weeks. The primary endpoint was to evaluate the proportion of patients who achieved an ASAS20 response at Week 16. Approximately 7% and 21% of patients used concomitant methotrexate or sulfasalazine, respectively from baseline to Week 16. Twenty-two percent of patients had an inadequate response to 1 or 2 TNF blockers. Clinical Response Patients treated with tofacitinib 5 mg twice daily achieved greater improvements in ASAS20 and ASAS40 responses compared to patients treated with placebo at Week 16 (Table 17). Consistent results were observed in the subgroup of patients who had an inadequate response to TNF blockers for both the ASAS20 (primary endpoint) and ASAS40 (secondary endpoint) at Week 16 (Table 17). The improvements in the components of the ASAS response and other measures of disease activity were greater in the tofacitinib 5 mg twice daily group compared to the placebo group as shown in Table 18. The percentage of patients with active AS who achieved ASAS20 response by visit is shown in Figure 6. Other Health-Related Outcomes Patients treated with tofacitinib 5 mg twice daily achieved greater improvements from baseline in Ankylosing Spondylitis Quality of Life (ASQoL) (-4.0 vs -2.0) compared to patients treated with placebo at Week 16. 1 1 1 14.4 Clinical Studies in Ulcerative Colitis The efficacy of tofacitinib tablets was evaluated in two 12-week induction studies (UC-I and UC-II), a 52-week maintenance study (UC-III), and a long-term extension study (UC-IV). Induction Trials (Study UC-I [NCT01465763] and Study UC-II [NCT01458951]) In two identical induction trials (UC-I and UC-II), 1139 adult patients were randomized (598 and 541 patients, respectively) to tofacitinib 10 mg twice daily or placebo with a 4:1 treatment allocation ratio. These trials included adult patients with moderately to severely active UC (total Mayo score of 6 to 12, with an endoscopy subscore of at least 2, and rectal bleeding subscore of at least 1) and who had failed or were intolerant to at least 1 of the following treatments: oral or intravenous corticosteroids, azathioprine, 6-MP or TNF blocker. tofacitinib and tofacitinib extended-release are indicated only for use in patients who have had inadequate response or intolerance to one or more TNF blockers [see Indications and Usage (1.4) ]. The disease activity was assessed by Mayo scoring index (0 to 12) which consists of four subscores (0 to 3 for each subscore): stool frequency, rectal bleeding, findings on endoscopy, and physician global assessment. An endoscopy subscore of 2 was defined by marked erythema, absent vascular pattern, any friability, and erosions; an endoscopy subscore of 3 was defined by spontaneous bleeding and ulceration. Patients were permitted to use stable doses of oral aminosalicylates and corticosteroids (prednisone daily dose up to 25 mg equivalent). Concomitant immunosuppressants (oral immunomodulators or biologic therapies) were not permitted for UC patients during these studies. A total of 52%, 73% and 72% of patients had previously failed or were intolerant to TNF blockers (51% in Study UC-1 and 52% in Study UC-II), corticosteroids (75% in Study UC-I and 71% in Study UC-II), and/or immunosuppressants (74% in Study UC-I and 70% in Study UC-II), respectively. Oral corticosteroids were received as concomitant treatment for UC by 47% of patients (45% in Study UC-I and 48% in Study UC-II) and 71% received concomitant aminosalicylates as treatment for UC (71% in Study UC-I, and 72% in Study UC-II). The baseline clinical characteristics were generally similar between the tofacitinib-treated patients and placebo-treated patients. The primary endpoint of Study UC-I and Study UC-II was the proportion of patients in remission at Week 8, and the key secondary endpoint was the proportion of patients with improvement of endoscopic appearance of the mucosa at Week 8. The efficacy results of Study UC-I and Study UC-II based on the centrally read endoscopy results are shown in Table 19. * p-value <0.01, ** p-value <0.001. CI = Confidence interval; N = number of patients in the analysis set; TNF = tumor necrosis factor a Remission was defined as clinical remission (a Mayo score ≤2 with no individual subscore >1) and rectal bleeding subscore of 0. b Prior TNF blocker failure was defined in this program as inadequate response, loss of response, or intolerance to TNF blocker therapy. c Patients in this group had failed one or more conventional therapies (corticosteroid, azathioprine, 6-mercaptopurine) but did not have history of prior failure of TNF blocker therapy. d Improvement of endoscopic appearance of the mucosa was defined as Mayo endoscopy subscore of 0 (normal or inactive disease) or 1 (erythema, decreased vascular pattern). e Tofacitinib and tofacitinib extended-release are indicated only for use in patients who have had inadequate response or intolerance to one or more TNF blockers [see Indications and Usage (1.4) ]. Clinical Response at Week 8 Clinical response was defined as a decrease from baseline in Mayo score of ≥3 points and ≥30%, with an accompanying decrease in the subscore for rectal bleeding of ≥1 point or absolute subscore for rectal bleeding of 0 or 1. Clinical response was observed in 60% of patients treated with tofacitinib 10 mg twice daily compared to 33% of patients treated with placebo in Study UC-I and 55% compared to 29% in Study UC-II. Normalization of the Endoscopic Appearance of the Mucosa at Week 8 Normalization of endoscopic appearance of the mucosa was defined as a Mayo endoscopic subscore of 0 and was observed in 7% of patients treated with tofacitinib 10 mg twice daily compared to 2% of treated with placebo in both Studies UC-I and UC-II. Rectal Bleeding and Stool Frequency Decreases in rectal bleeding and stool frequency subscores were observed as early as Week 2 in patients treated with tofacitinib. Maintenance Trial (Study UC-III [NCT01458574]) A total of 593 adult patients who completed the induction trials (UC-I or UC-II) and achieved clinical response were re-randomized with 1:1:1 treatment allocation ratio to tofacitinib 5 mg twice daily, tofacitinib 10 mg twice daily, or placebo for 52 weeks in Study UC-III. Tofacitinib 5 mg twice daily is the recommended dosage for maintenance therapy; limit use of tofacitinib 10 mg twice daily beyond induction to those with loss of response and should be used for the shortest duration [see Dosage and Administration (2.4)]. As in the induction trials, patients were permitted to use stable doses of oral aminosalicylates; however, corticosteroid tapering was required upon entrance into this study for patients who were receiving corticosteroids at baseline. Concomitant immunosuppressants (oral immunomodulators or biologic therapies) were not permitted. At baseline of Study UC-III: 179 (30%) patients were in remission 289 (49%) patients were receiving oral corticosteroids 265 (45%), 445 (75%), and 413 (70%) patients had previously failed or were intolerant to TNF blocker therapy, corticosteroids, and immunosuppressants, respectively. Tofacitinib and tofacitinib extended-release are indicated only for use in patients who have had inadequate response or intolerance to one or more TNF blockers [see Indications and Usage (1.4) ]. In Study UC-III, the primary endpoint was the proportion of patients in remission at Week 52. There were two key secondary endpoints: the proportion of patients with improvement of endoscopic appearance at Week 52, and the proportion of patients with sustained corticosteroid-free remission at both Week 24 and Week 52 among patients in remission at baseline of Study UC-III. The efficacy results of Study UC-III based on the centrally read endoscopy results are summarized in Table 20. * p-value <0.0001. CI = Confidence interval; N = number of patients in the analysis set; TNF = tumor necrosis factor. a Remission was defined as clinical remission (a Mayo score ≤2 with no individual subscore >1) and rectal bleeding subscore of 0. b Prior TNF blocker failure was defined in this program as inadequate response, loss of response, or intolerance to TNF blocker therapy. c Patients in this group had failed one or more conventional therapies (corticosteroid, azathioprine, 6-mercaptopurine) but did not have history of prior failure of TNF blocker therapy. d Improvement of endoscopic appearance of the mucosa was defined as Mayo endoscopy subscore of 0 (normal or inactive disease) or 1 (erythema, decreased vascular pattern). e Sustained corticosteroid-free remission was defined as being in remission and not taking corticosteroids for at least 4 weeks prior to the visit at both Week 24 and Week 52. f Tofacitinib and Tofacitinib extended-release are indicated only for use in patients who have had inadequate response or intolerance to one or more TNF blockers [see Indications and Usage (1.4) ]. Maintenance of Clinical Response Maintenance of clinical response was defined as the proportion of patients who met the definition of clinical response (defined as a decrease from the induction study (UC-I, UC-II) baseline Mayo score of ≥3 points and ≥30%, with an accompanying decrease in the rectal bleeding subscore of ≥1 point or rectal bleeding subscore of 0 or 1) at both Baseline and Week 52 of Study UC-III. Maintenance of clinical response was observed in 20% in the placebo group, 52% in the tofacitinib 5 mg twice daily group, and 62% in the tofacitinib 10 mg twice daily group. Maintenance of Remission (Among Patients in Remission at Baseline) In the 179 patients who were in remission at baseline of Study UC-III (N = 59 for placebo, N = 65 for tofacitinib 5 mg twice daily, N = 55 for tofacitinib 10 mg twice daily), 10% in the placebo group, 46% in the tofacitinib 5 mg twice daily group and 56% in the tofacitinib 10 mg twice daily group maintained remission at Week 52. Normalization of the Endoscopic Appearance of the Mucosa Normalization of endoscopic appearance of the mucosa was defined as a Mayo endoscopic subscore of 0 and was observed at Week 52 in 15% of patients in the tofacitinib 5 mg twice daily group and 17% of patients in the tofacitinib 10 mg twice daily group compared to 4% of placebo patients. Open-label Extension Study (Study UC-IV [NCT01470612]) In Study UC-IV, 914 patients were treated of which 156 received tofacitinib 5 mg twice daily and 758 received tofacitinib 10 mg twice daily. Of the 905 patients who were assigned to tofacitinib 10 mg twice daily in the 8-week induction studies (Study UC-I or Study UC-II), 322 patients completed the induction studies but did not achieve clinical response. Of these 322 patients, 291 continued to receive tofacitinib 10 mg twice daily (unblinded) and had available data after an additional 8 weeks in Study UC-IV. After 8 additional weeks (a total of 16 weeks treatment), 148 patients achieved clinical response, and 25 patients achieved remission (based on central endoscopy read). Among those 143 patients who achieved clinical response by 16 weeks and had available data at Week 52, 66 patients achieved remission (based on local endoscopy read) after continued treatment with tofacitinib 10 mg twice daily for 52 weeks. 1 1 14.5 Safety Study in Adults with Rheumatoid Arthritis (Tofacitinib Versus TNF-blocker) A randomized open-label trial (RA Safety Study 1; NCT02092467) was conducted to evaluate safety with tofacitinib at two doses, 5 mg twice daily (N=1455) and 10 mg twice daily (N=1456), versus the TNF-blocker control (N=1451) in RA patients 50 years of age and older with at least one cardiovascular risk factor. The co-primary endpoints were adjudicated MACE (defined as cardiovascular death, non-fatal MI, and non-fatal stroke) and adjudicated malignancy (excluding non-melanoma skin cancer). The study was designed to exclude a prespecified risk margin of 1.8 for the hazard ratio of combined tofacitinib regimens versus the TNF-blocker control for each co-primary endpoint. An independent committee conducted a blinded evaluation of the co-primary endpoints according to predefined criteria (adjudication). The study was event-driven and patients were followed until a sufficient number of primary outcome events accrued. Other endpoints included mortality, serious infections, and thromboembolic events. The median on-study follow-up time was 4 years. The mean age of the population was 61 years (range: 50 to 88 years). Most patients were female (78%) and Caucasian (77%). Patients had a diagnosis of RA for a mean of 10 years, and a median swollen and tender joint count of 11 and 15 respectively. Cardiovascular risk factors included cigarette smoking (current or past) (48%), hypertension (66%), high density lipoprotein <40 mg/d L (12%), diabetes mellitus (17%), family history of premature coronary heart disease (15%), extra-articular disease associated with RA (37%), and history of coronary artery disease (11%). The non-inferiority criterion was not met for the primary comparison of the combined tofacitinib dosages to TNF blockers since the upper limit of the 95% CI exceeded the pre-specified non-inferiority criterion of 1.8 (for MACE, the upper limit of the 95% CI was 1.94; for malignancies excluding NMSC, the upper limit of the 95% CI was 2.09). Table 21 shows the study results for each of the co-primary endpoints, and other endpoints. There was an increased risk of death, MACE, malignancies, serious infections, thromboembolic events and fractures associated with both dosages of tofacitinib. Note: Tofacitinib 10 mg twice daily was discontinued by the Data Monitoring Committee due to safety concerns, and ongoing patients switched from tofacitinib 10 mg to tofacitinib 5 mg. The column “Tofacitinib 10 mg Twice Daily” includes all events and follow-up for patients randomized to tofacitinib 10 mg twice daily. A tofacitinib (refers to tablets and oral solution) 10 mg twice daily (or a tofacitinib extended-release tablets 22 mg once daily) dosage is not recommended for the treatment of RA, Ps A, or AS [see Dosage and Administration (2.3) ]. N indicates number of patients; n indicates number of patients with events. IR indicates incidence rate per 100 person-year (PY). †MI and Stroke include fatal and non-fatal events. ††Data and analyses for Malignancies excluding NMSC for current and ex-smokers are included. There were 720 current and ex-smokers randomized to tofacitinib 5 mg, 704 to tofacitinib 10 mg, and 679 to TNF blockers. *HR (95%) CI for tofacitinib vs. TNF Blocker (Univariate Cox Proportional Hazard Model). NMSC: Non-melanoma Skin Cancer; MACE: Major Adverse Cardiac Events; HR: Hazard Ratio; DVT: Deep Vein Thrombosis; PE: Pulmonary Embolism; VTE: Venous Thromboembolism, first occurrence of a VTE, defined as the composite of adjudicated DVT and adjudicated PE; ATE: Arterial Thromboembolism; TE: Thromboembolism, first occurrence of a TE, defined as the composite of adjudicated VTE and unadjudicated ATE. Lymphomas and lung cancers, which are a subset of all malignancies in RA Safety Study 1, were observed at a higher rate in patients treated with tofacitinib 5 mg twice a day and tofacitinib 10 mg twice a day compared to those treated with TNF blockers. Lymphoma was reported for 4 patients who received tofacitinib 5 mg twice a day, 6 patients who received tofacitinib 10 mg twice a day, and 1 patient who received TNF blockers (Incidence Rate [IR] of 0.07, 0.11, and 0.02 per 100 patient-years, respectively). Among current and past smokers, lung cancer was reported for 13 patients who received tofacitinib 5 mg twice a day, 15 patients who received tofacitinib 10 mg twice a day, and 7 patients who received TNF blockers (IR of 0.48, 0.59, and 0.27 per 100 patient-years, respectively). Given these increased risks, tofacitinib 10 mg twice daily (or tofacitinib extended-release tablets 22 mg once daily) dosage is not recommended for the treatment of RA, Ps A, or AS [see Dosage and Administration (2.3) ]. The overall fractures and osteoporotic fractures were observed at a higher rate in both tofacitinib treatment groups compared to the TNF blocker treatment group. The observed incidence rate of osteoporotic fractures was higher in women than men, and was highest in women on tofacitinib10 mg twice daily (1.56 per 100 patient-years), followed by tofacitinib 5 mg twice daily (1.26 per 100 patient-years), and TNF blockers (1.01 per 100 patient-years). 1" ], "how_supplied": [ "16 HOW SUPPLIED/STORAGE AND HANDLING How Supplied Information for Tofacitinib Extended-Release Tablets How supplied information tofacitinib extended-release tablets is shown in Table 22.
