Prophylaxis of invasive Aspergillus and Candida infections: Duration of therapy is based on recovery from neutropenia or immunosuppression. 2.5 Preparation of Posaconazole Injection Preparation of Posaconazole Injection : • Remove the vial of posaconazole injection from the refrigerator and allow to equilibrate to room temperature prior to use . • To prepare the required dose, aseptically transfer one vial of posaconazole injection (containing 300 mg of posaconazole in 16.7 mL of solution) to an intravenous bag or bottle of one of the following compatible diluents to achieve a final posaconazole concentration between 1 mg/mL and 2 mg/mL : o 0.45% Sodium Chloride Injectio n o 0.9% Sodium Chloride Injectio n o 5% Dextrose Injectio n o 5% Dextrose and 0.45% Sodium Chloride Injectio n o 5% Dextrose and 0.9% Sodium Chloride Injectio n o 5% Dextrose and 20 mEq Potassium Chloride Injectio n Use of other diluents is not recommended because they may result in particulate formation . • Discard any unused posaconazole injection from the vial. • Parenteral drug products should be inspected visually for particulate matter prior to administration, whenever solution and container permit. Once admixed, the diluted posaconazole infusion solution ranges from colorless to yellow (variations of color within this range do not affect the quality of the product ). • Immediately use the diluted posaconazole infusion solution, once admixed. If not used immediately, refrigerate (2° to 8°C (36° to 46°F)) the diluted posaconazole infusion solution up to 24 hours. Discard any unused portion . Incompatible Diluent s Co-administration of drug products besides the infusion solutions or products stated above are not recommended because this may result in particulate formation. The following diluents were determined to be incompatible with posaconazole injection; thus, do not dilute posaconazole injection with them : • Lactated Ringer’s Injectio n • Lactated Ringer's and 5% Dextrose Injectio n • 4.2% Sodium Bicarbonate Injectio n 2.6 Administration of Diluted Posaconazole Infusion Solution See Dosage and Administration (2.5) for the preparation instructions for the diluted posaconazole solution . Important Administration Instructions for the Diluted Posaconazole Infusion Solutio n • Must administer diluted posaconazole infusion solution through a 0.22-micron polyethersulfone (PES) or polyvinylidene difluoride (PVDF) filter . • Administer diluted posaconazole infusion solution via a central venous line, including a central venous catheter (CVC) or peripherally inserted central catheter (PICC), by slow intravenous infusion over approximately 90 minutes [see Adverse Reactions (6.1) ] • If a CVC or PICC are not available, may administer diluted posaconazole solution once through a peripheral venous catheter by intravenous infusion over approximately 30 minutes to bridge the period during which a CVC or PICC are replaced, inserted, or unavailable for use (e.g., the CVC is being used for intravenous treatment with another product). However, do not administer diluted posaconazole infusion solution more than once via peripheral venous catheter because in clinical trials, multiple peripheral infusions given through the same vein resulted in infusion site reactions [see Adverse Reactions (6.1) ] . • When multiple dosing is required, the infusion should be done via a central venous line . Additional Administration Instructions for the Diluted Posaconazole Infusion Solutio n • Administer diluted posaconazole infusion solution intravenously through the same intravenous line (or cannula) with the following compatible infusion solutions : o 0.45% Sodium Chloride Injection o 0.9% Sodium Chloride Injection o 5% Dextrose Injection o 5% Dextrose and 0.45% Sodium Chloride Injection o 5% Dextrose and 0.9% Sodium Chloride Injection o 5% Dextrose and 20 mEq potassium chloride Injection • Administer diluted posaconazole infusion solution intravenously at the same time through the same intravenous line (or cannula) with the following intravenous drug products prepared in 5% Dextrose Injection or 0.9% Sodium Chloride Injection : o Amikacin Sulfate Injection o Caspofungin Acetate for Injection o Ciprofloxacin Injection o Daptomycin for Injection o Dobutamine Injection o Famotidine Injection o Filgrastim Injection o Gentamicin Injection o Hydromorphone Hydrochloride Injection o Levofloxacin Injection o Lorazepam Injection o Meropenem for Injection o Micafungin for Injection o Morphine Sulfate Injection o Norepinephrine Bitartrate Injection o Potassium Chloride Injection o Vancomycin Hydrochloride for Injection 2.11 Dosage Modifications in Patients with Renal Impairment Avoid the use of posaconazole injection in patients with eGFR less than 50 mL/minute/1.73 m 2 , unless an assessment of the benefit/risk to the patient justifies its use.

( 4.1 ) • Coadministration of posaconazole with the following drugs is contraindicated; posaconazole increases concentrations and toxicities of: • Sirolimus: ( 4.2 , 7.2 ) • CYP3A4 substrates (pimozide, quinidine): can result in QTc interval prolongation and cases of torsades de pointes (TdP) ( 4.3 , 5.2 , 7.2 ) • HMG-CoA Reductase Inhibitors Primarily Metabolized through CYP3A4 ( 4.4 , 7.2 ) • Ergot alkaloids ( 4.5 , 7.2 ) • Venetoclax: In patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) at initiation and during the ramp-up phase ( 4.6 , 5.11 , 7.2 ) 4.1 Hypersensitivity Posaconazole is contraindicated in persons with known hypersensitivity to posaconazole or other azole antifungal agents. 4.2 Use with Sirolimus Posaconazole is contraindicated with sirolimus. Concomitant administration of posaconazole with sirolimus increases the sirolimus blood concentrations by approximately 9-fold and can result in sirolimus toxicity [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . 4.3 QT Prolongation with Concomitant Use with CYP3A4 Substrates Posaconazole is contraindicated with CYP3A4 substrates that prolong the QT interval. Concomitant administration of posaconazole with the CYP3A4 substrates, pimozide and quinidine may result in increased plasma concentrations of these drugs, leading to QTc prolongation and cases of torsades de pointes [see Warnings and Precautions (5.2) and Drug Interactions (7.2) ] . 4.4 HMG-CoA Reductase Inhibitors Primarily Metabolized Through CYP3A4 Coadministration with the HMG-CoA reductase inhibitors that are primarily metabolized through CYP3A4 (e.g., atorvastatin, lovastatin, and simvastatin) is contraindicated since increased plasma concentration of these drugs can lead to rhabdomyolysis [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . 4.5 Use with Ergot Alkaloids Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism [see Drug Interactions (7.2) ] . 4.6 Use with Venetoclax Coadministration of posaconazole with venetoclax at initiation and during the ramp-up phase is contraindicated in patients with chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) due to the potential for increased risk of tumor lysis syndrome [see Warnings and Precautions (5.11) and Drug Interactions (7.2) ] ." ], "warnings_and_cautions": [ "5 WARNINGS AND PRECAUTIONS • Calcineurin-Inhibitor Toxicity : Posaconazole increases concentrations of cyclosporine or tacrolimus; reduce dose of cyclosporine and tacrolimus and monitor concentrations frequently. ( 5.1 ) • Arrhythmias and QTc Prolongation : Posaconazole has been shown to prolong the QTc interval and cause cases of TdP. Administer with caution to patients with potentially proarrhythmic conditions. Do not administer with drugs known to prolong QTc interval and metabolized through CYP3A4. ( 5.2 , 7.2 ) • Electrolyte Disturbances : Monitor and correct, especially those involving potassium (K + ), magnesium (Mg ++ ), and calcium (Ca ++ ), before and during posaconazole therapy. ( 5.3 ) • Pseudoaldosteronism : Manifested by the onset or worsening of hypertension, and abnormal laboratory findings. Monitor blood pressure and potassium levels, and manage as necessary. ( 5.4 ) • Hepatic Toxicity : Elevations in liver tests may occur. Discontinuation should be considered in patients who develop abnormal liver tests or monitor liver tests during treatment. ( 5.5 ) • Renal Impairment : Posaconazole injection should be avoided in patients with moderate or severe renal impairment (eGRF less than 50 mL/min1.73m 2 ), unless an assessment of the benefit/risk to the patient justifies the use of posaconazole injection. ( 5.6 , 8.6 ) • Concomitant Use with Midazolam : Posaconazole can prolong hypnotic/sedative effects. Monitor patients and benzodiazepine receptor antagonists should be available. ( 5.7 , 7.2 ) • Vincristine Toxicity : Concomitant administration of azole antifungals, including posaconazole, with vincristine has been associated with neurotoxicity and other serious adverse reactions; reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options. ( 5.8 , 7.2 ) • Venetoclax Toxicity : Concomitant administration of posaconazole with venetoclax may increase venetoclax toxicities, including the risk of tumor lysis syndrome, neutropenia, and serious infections; monitor for toxicity and reduce venetoclax dose. ( 4.6 , 5.11 , 7.2 ) 5.1 Calcineurin-Inhibitor Toxicity Concomitant administration of posaconazole with cyclosporine or tacrolimus increases the whole blood trough concentrations of these calcineurin-inhibitors [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . Nephrotoxicity and leukoencephalopathy (including deaths) have been reported in clinical efficacy studies in patients with elevated cyclosporine or tacrolimus concentrations. Frequent monitoring of tacrolimus or cyclosporine whole blood trough concentrations should be performed during and at discontinuation of posaconazole treatment and the tacrolimus or cyclosporine dose adjusted accordingly. 5.2 Arrhythmias and QT Prolongation Some azoles, including posaconazole, have been associated with prolongation of the QT interval on the electrocardiogram. In addition, cases of torsades de pointes have been reported in patients taking posaconazole. Results from a multiple time-matched ECG analysis in healthy volunteers did not show any increase in the mean of the QTc interval. Multiple, time-matched ECGs collected over a 12-hour period were recorded at baseline and steady-state from 173 healthy male and female volunteers (18-85 years of age) administered Noxafil ® oral suspension 400 mg twice daily with a high-fat meal. In this pooled analysis, the mean QTc (Fridericia) interval change from baseline was –5 msec following administration of the recommended clinical dose. A decrease in the QTc(F) interval (–3 msec) was also observed in a small number of subjects (n=16) administered placebo. The placebo-adjusted mean maximum QTc(F) interval change from baseline was <0 msec (–8 msec). No healthy subject administered posaconazole had a QTc(F) interval ≥500 msec or an increase ≥60 msec in their QTc(F) interval from baseline. Posaconazole should be administered with caution to patients with potentially proarrhythmic conditions. Do not administer with drugs that are known to prolong the QTc interval and are metabolized through CYP3A4 [see Contraindications (4.3) and Drug Interactions (7.2) ] . 5.3 Electrolyte Disturbances Electrolyte disturbances, especially those involving potassium, magnesium or calcium levels, should be monitored and corrected as necessary before and during posaconazole therapy. 5.4 Pseudoaldosteronism Pseudoaldosteronism, manifested by the onset of hypertension or worsening of hypertension, and abnormal laboratory findings (hypokalemia, low serum renin and aldosterone, and elevated 11-deoxycortisol), has been reported with posaconazole use in the postmarket setting. Monitor blood pressure and potassium levels and manage as necessary. Management of pseudoaldosteronism may include discontinuation of posaconazole, substitution with an appropriate antifungal drug that is not associated with pseudoaldosteronism, or use of aldosterone receptor antagonists. 5.5 Hepatic Toxicity Hepatic reactions (e.g., mild to moderate elevations in alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase, total bilirubin, and/or clinical hepatitis) have been reported in clinical trials. The elevations in liver tests were generally reversible on discontinuation of therapy, and in some instances these tests normalized without drug interruption. Cases of more severe hepatic reactions including cholestasis or hepatic failure including deaths have been reported in patients with serious underlying medical conditions (e.g., hematologic malignancy) during treatment with posaconazole. These severe hepatic reactions were seen primarily in subjects receiving the Noxafil oral suspension 800 mg daily (400 mg twice daily or 200 mg four times a day) in clinical trials. Liver tests should be evaluated at the start of and during the course of posaconazole therapy. Patients who develop abnormal liver tests during posaconazole therapy should be monitored for the development of more severe hepatic injury. Patient management should include laboratory evaluation of hepatic function (particularly liver tests and bilirubin). Discontinuation of posaconazole must be considered if clinical signs and symptoms consistent with liver disease develop that may be attributable to posaconazole. 5.6 Renal Impairment Posaconazole injection should be avoided in patients with moderate or severe renal impairment (eGFR < 50 mL/1.73 m 2 ), unless an assessment of the benefit/risk to the patient justifies the use of posaconazole injection. In patients with moderate or severe renal impairment (eGFR < 50 mL/1.73 m 2 ), receiving the posaconazole injection, accumulation of the intravenous vehicle, SBECD, is expected to occur. Serum creatinine levels should be closely monitored in these patients, and, if increases occur, consideration should be given to changing to oral posaconazole therapy [see Dosage and Administration (2.11) and Use in Specific Populations (8.6) ] . 5.7 Midazolam Toxicity Concomitant administration of posaconazole with midazolam increases the midazolam plasma concentrations by approximately 5-fold. Increased plasma midazolam concentrations could potentiate and prolong hypnotic and sedative effects. Patients must be monitored closely for adverse effects associated with high plasma concentrations of midazolam and benzodiazepine receptor antagonists must be available to reverse these effects [see Drug Interactions (7.2) and Clinical Pharmacology (12.3) ] . 5.8 Vincristine Toxicity Concomitant administration of azole antifungals, including posaconazole, with vincristine has been associated with neurotoxicity and other serious adverse reactions, including seizures, peripheral neuropathy, syndrome of inappropriate antidiuretic hormone secretion, and paralytic ileus. Reserve azole antifungals, including posaconazole, for patients receiving a vinca alkaloid, including vincristine, who have no alternative antifungal treatment options [see Drug Interactions (7.2) ] . 5.11 Venetoclax Toxicity Concomitant administration of posaconazole, a strong CYP3A4 inhibitor, with venetoclax may increase venetoclax toxicities, including the risk of tumor lysis syndrome (TLS), neutropenia, and serious infections. In patients with CLL/SLL, administration of posaconazole during initiation and the ramp-up phase of venetoclax is contraindicated [see Contraindications (4.6) ] . Refer to the venetoclax labeling for safety monitoring and dose reduction in the steady daily dosing phase in CLL/SLL patients. For patients with acute myeloid leukemia (AML), dose reduction and safety monitoring are recommended across all dosing phases when coadministering posaconazole with venetoclax [see Drug Interactions (7.2) ] . Refer to the venetoclax prescribing information for dosing instructions." ], "adverse_reactions": [ "6 ADVERSE REACTIONS The following serious and otherwise important adverse reactions are discussed in detail in another section of the labeling: • Arrhythmias and QT Prolongation [see Warnings and Precautions (5.2) ] • Electrolyte and Disturbances [see Warnings and Precautions (5.3) ] • Pseudoaldosteronism [see Warnings and Precautions (5.4) ] • Hepatic Toxicity [see Warnings and Precautions (5.5) ] • Adult Patients: Common adverse reactions in studies with posaconazole in adults are diarrhea, nausea, fever, vomiting, headache, coughing, and hypokalemia. ( 6.1 ) • Pediatric Patients: Common adverse reactions (incidence >20% receiving 6 mg/kg posaconazole injection) in a study in pediatric patients are pyrexia, febrile neutropenia, vomiting, mucosal inflammation, pruritus, hypertension, hypokalemia, and stomatitis.

Treatment of Invasive Aspergillosis in Adults and Adolescents (Posaconazole Injection and Noxafil Delayed-Release Tablets) The safety of posaconazole injection and Noxafil delayed-release tablets was assessed in a randomized, double-blind, active-controlled clinical study of posaconazole injection and Noxafil delayed-release tablets versus voriconazole for treatment of invasive aspergillosis (Aspergillosis Treatment Study). A total of 575 adult and pediatric patients 14 years of age and older (288 in posaconazole group, 287 in voriconazole group (voriconazole for injection or voriconazole tablets)) with proven, probable or possible invasive aspergillosis were included. The median duration of treatment was 67 days for posaconazole injection or Noxafil delayed-release tablets and 64 days for voriconazole. In this study, 55% to 60% of patients started intravenous treatment with posaconazole injection or voriconazole (voriconazole injection). The median duration of the first instance of intravenous treatment (before switching to oral treatment or discontinuing or completing study treatment) was 9 days for both groups. Table 7 presents adverse reactions reported at an incidence of ≥ 10% in either one of the treatment groups in Aspergillosis Treatment Study. Adverse reactions leading to treatment discontinuation were reported for 34% of patients. The most commonly reported adverse reactions (> 2% of patients) leading to treatment discontinuation were septic shock, respiratory failure, and bronchopulmonary aspergillosis in the posaconazole group, and septic shock and acute myeloid leukemia in the voriconazole group. The most frequently reported adverse reactions in the posaconazole-treated group were pyrexia (28%), hypokalemia (28%), and nausea (23%).

Therefore, in subsequent studies, posaconazole injection was administered via central venous catheter [see Dosage and Administration (2.6) ] . The safety of posaconazole injection has been assessed in 268 patients in a clinical trial. Patients were enrolled in a non-comparative pharmacokinetic and safety trial of posaconazole injection when given as antifungal prophylaxis (Posaconazole Injection Study). Patients were immunocompromised with underlying conditions including hematological malignancy, neutropenia post-chemotherapy, GVHD, and post HSCT. This patient population was 55% male, had a mean age of 51 years (range 18-82 years, 19% of patients were ≥ 65 years of age), and were 95% White and 8% Hispanic. In this study, 10 patients received a single dose of 200 mg posaconazole injection, 21 patients received 200 mg daily dose for a median of 14 days, and 237 patients received 300 mg daily dosage for a median of 9 days (the 200 mg dosage is not a recommended dosage for prophylaxis of invasive Aspergillus and Candida infections in adults [see Dosage and Administration (2.2) ] . In the 300 mg daily dosage group each patient received a loading intravenous dose of posaconazole injection 300 mg twice on Day 1, then intravenous posaconazole injection therapy, and finally Noxafil oral suspension to complete 28 days of total posaconazole therapy. Table 8 presents adverse reactions observed in patients treated with the posaconazole injection 300 mg daily dosage group in the posaconazole injection Study. The most frequently reported adverse reactions with an onset during the intravenous posaconazole injection phase of dosing with 300 mg once daily were diarrhea (32%), hypokalemia (22%), pyrexia (21%), and nausea (19%). These adverse reactions were consistent with those seen in studies with Noxafil oral suspension.

Clinical Trials in Pediatric Patients 2 Years of Age and Older The safety of posaconazole injection and Noxafil PowderMix (for delayed-release oral suspension) for prophylaxis of invasive fungal infections was evaluated in an open-label uncontrolled dose-ranging pharmacokinetic and safety study of posaconazole injection/Noxafil PowderMix (Pediatric Study 1, NCT02452034). In this study, in 115 immunocompromised pediatric patients 2 to less than 18 years of age with known or expected neutropenia initially received posaconazole injection (up to 6 mg/kg (twice daily for the first day and then up to 6 mg/kg for at least 7 days), and then 63 patients were transitioned to Noxafil PowderMix (up to 6 mg/kg once daily). The mean overall treatment duration was 21 days including a mean duration of 14 days (range: 1 to 28 days) on posaconazole injection and a mean duration of 12 days (range: 2 to 18 days) on Noxafil PowderMix [see Clinical Pharmacology (12.3) ] . In this study, the reported adverse reaction profile of posaconazole injection and Noxafil PowderMix in pediatric patients was consistent with the safety profile of posaconazole in adults. The most common adverse reactions that occurred in greater than 20% of pediatric patients who received posaconazole injection and Noxafil PowderMix were pyrexia, febrile neutropenia, vomiting, mucosal inflammation, pruritus, hypertension, hypokalemia, and stomatitis. The safety of posaconazole injection, Noxafil delayed-release tablets, and Noxafil PowderMix for delayed-release oral suspension for the treatment of invasive aspergillosis was evaluated in an open-label, non-comparative clinical study in 31 pediatric patients 2 to less than 18 years of age with a diagnosis of possible, probable, or proven invasive aspergillosis (Pediatric Study 2, NCT04218851). In this study, all 31 pediatric patients initially received posaconazole injection (6 mg/kg twice daily on the first day and then 6 mg/kg once daily) for the treatment of invasive aspergillosis; 12 patients were transitioned to Noxafil delayed-release tablets (300 mg once daily) if they weighed ≥ 40 kg, and 10 patients were transitioned to Noxafil PowderMix (based on weight) if they weighed 10 to 40 kg [see Dosage and Administration (2.3) ] . The mean overall treatment duration was 50 days including 15 days (range 2 to 78 days) on posaconazole injection, 54 days (range: 6 to 80 days) on Noxafil delayed-release tablets, and 44 days (range 7 to 76 days) on Noxafil PowderMix. The reported adverse reaction profile of posaconazole injection, Noxafil delayed-release tablets, and Noxafil PowderMix in pediatric patients was consistent with the known safety profile of posaconazole in adults. The most common adverse reactions that occurred in greater than 20% of pediatric patients who received any of the three formulations of posaconazole were vomiting, pyrexia, abdominal pain, liver test abnormalities, and hypertension. 6.2 Postmarketing Experience The following adverse reaction has been identified during the post-approval use of posaconazole.

" ], "drug_interactions": [ "7 DRUG INTERACTIONS Table 15 and Table 17 include drugs with clinically important drug interactions when administered concomitantly with posaconazole and instructions for preventing or managing them. These recommendations are based on either drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious adverse reactions or loss of efficacy [see Clinical Pharmacology (12.3) ] . The following information was derived from data with Noxafil oral suspension or another posaconazole tablet formulation unless otherwise noted. All clinically important drug interactions with Noxafil oral suspension, except for those that affect the absorption of posaconazole (via gastric pH and motility), are considered relevant to clinically important drug interactions with posaconazole injection. Consult the labeling of concomitantly used drugs to obtain further information about interactions with posaconazole. Interaction Drug Interaction Rifabutin, phenytoin, efavirenz Avoid coadministration unless the benefit outweighs the risks ( 7.1 , 7.2 ) Other drugs metabolized by CYP3A4 Consider dosage adjustment and monitor for adverse effects and toxicity ( 7.2 ) Digoxin Monitor digoxin plasma concentrations ( 7.2 ) Fosamprenavir Monitor for breakthrough fungal infections ( 7.1 ) 7.1 Effects of Other Drugs on Posaconazole Posaconazole is primarily metabolized via UDP-glucuronosyltransferase and is a substrate of p-glycoprotein (P-gp) efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. Concomitant use of posaconazole with drugs that can decrease the plasma posaconazole concentrations should generally be avoided unless the benefit outweighs the risk. If such drugs are necessary, patients should be monitored closely for breakthrough fungal infections. Table 15: Drug Interactions Affecting Posaconazole When Administered Concomitantly with Other Drugs UDP-Glucuronidase Inducers Mechanism and Clinical Effect(s) Posaconazole is a UDP-glucuronosyltransferase substrate. Concomitant use of posaconazole with UDP-glucuronidase inducers may decrease posaconazole exposure [see Clinical Pharmacology (12.3) ], which may reduce the effectiveness of posaconazole. Prevention or Management Efavirenz Avoid concomitant use of posaconazole with efavirenz, unless the benefit outweighs the risks. Rifabutin Avoid concomitant use of posaconazole with rifabutin unless the benefit to the patient outweighs the risk. If concomitant use is needed, monitor closely for breakthrough fungal infections.

Prevention or Management Verapamil, Diltiazem, Nifedipine, Nicardipine, Felodipine Monitor frequently for adverse reactions and toxicity with concomitant use of posaconazole with calcium channel blockers that are CYP3A4 substrates. Dosage reduction of the calcium channel blocker may be needed. Anti-HIV Drugs that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Ritonavir and atazanavir are CYP3A4 substrates and posaconazole increased plasma concentrations of these drugs [see Clinical Pharmacology (12.3) ] . Prevention or Management Ritonavir and Atazanavir Monitor frequently for adverse reactions and toxicity of ritonavir and atazanavir during concomitant use. Antineoplastic Drugs that are CYP3A4 Substrates Mechanism and Clinical Effect(s) Posaconazole may increase plasma concentrations of oncology drugs that are CYP3A4 substrates, which may increase the risk of serious adverse reactions. Prevention or Management Venetoclax CLL/SLL patients: Concomitant use of posaconazole with venetoclax during initiation and ramp-up phase is contraindicated. AML patients: With concomitant use, venetoclax dosage reduction and safety monitoring is recommended across all dosing phases [see Warnings and Precautions (5.11) ] . Vinca alkaloids (e.g., vincristine, vinblastine) Reserve concomitant use for patients with no alternative antifungal treatment options [see Warnings and Precautions (5.8) ]. Ergot Alkaloids Mechanism and Clinical Effect(s) Most of the ergot alkaloids are CYP3A4 substrates. Posaconazole may increase the plasma concentrations of ergot alkaloids (ergotamine and dihydroergotamine) which may lead to ergotism. Prevention or Management Ergotamine, Dihydroergotamine Concomitant use with posaconazole is contraindicated. Phenytoin Mechanism and Clinical Effect(s) Phenytoin is a CYP3A4 substrate.

Prevention or Management Avoid concomitant use of posaconazole with phenytoin unless the benefit outweighs the risk. frequently monitor phenytoin concentrations and consider a dosage reduction of phenytoin. See Table 15 for additional monitoring considerations when phenytoin affects posaconazole via UDP-glucuronosyltransferase inhibition. Rifabutin Mechanism and Clinical Effect(s) Rifabutin is a CYP3A4 substrate. Concomitant use of posaconazole with rifabutin increased rifabutin plasma concentrations [see Clinical Pharmacology (12.3) ] . Prevention or Management Avoid concomitant use of posaconazole with rifabutin unless the benefit outweighs the risk. Frequent monitoring of full blood counts and adverse reactions due to increased rifabutin plasma concentrations (e.g., uveitis, leukopenia) during concomitant use are recommended. See Table 15 for additional monitoring considerations when rifabutin affects posaconazole via UDP-glucuronosyltransferase inhibition. 7.3 Absence of Clinically Important Interaction with Posaconazole Additional clinical studies demonstrated that no clinically important effects on zidovudine, lamivudine, indinavir, or caffeine were observed when administered with Noxafil 200 mg once daily; therefore, no dose adjustments are required for these drugs when coadministered with Noxafil 200 mg once daily." ], "drug_interactions_table": [ "

( 8.1 ) • Pediatrics: Safety and effectiveness in patients younger than 2 years of age have not been established. ( 8.4 ) • Severe Renal Impairment: Monitor closely for breakthrough fungal infections. ( 8.6 ) 8.1 Pregnancy Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women. Available data for use of posaconazole in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, skeletal malformations were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥ 1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers. In pregnant rabbits dosed orally during organogenesis, doses of ≥ 3 times the clinical exposure caused an increase in resorptions (see Data ) . Based on animal data, advise pregnant women of the potential risk to a fetus. The estimated background risk of major birth defects and miscarriage for the indicated populations is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. Data Animal Data Posaconazole resulted in maternal toxicity (reduced food consumption and reduced body weight gain) and skeletal malformations (cranial malformations and missing ribs) when given orally to pregnant rats during organogenesis (Gestational Days 6 through 15) at doses ≥27 mg/kg (≥1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of drug in healthy volunteers). The no-effect dose for malformations and maternal toxicity in rats was 9 mg/kg, which is 0.7 times the exposure achieved with the 400 mg twice daily oral suspension regimen. No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions. In rabbits dosed at 80 mg/kg, a reduction in body weight gain of females and a reduction in litter size were seen. 8.2 Lactation Risk Summary There are no data on the presence of posaconazole in human milk, the effects on the breastfed infant, or the effects on milk production. Posaconazole is excreted in the milk of lactating rats. When a drug is present in animal milk, it is likely that the drug will be present in human milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for posaconazole and any potential adverse effects on the breastfed child from posaconazole or from the underlying maternal condition. 8.4 Pediatric Use Treatment of Invasive Aspergillosis The safety and effectiveness of posaconazole injection have been established for the treatment of invasive aspergillosis in pediatric patients 2 years of age and older. Use of posaconazole for these pediatric indications is supported by evidence from adequate and well-controlled studies of posaconazole in adults and safety and pharmacokinetic (PK) data from two pediatric studies [see Adverse Reactions (6.1) and Clinical Pharmacology (12.3) ] . The safety of posaconazole in pediatric patients for these pediatric indications was consistent with the known safety profile of posaconazole in adults [see Adverse Reactions (6.1) ] . The safety and effectiveness of posaconazole have not been established in pediatric patients less than 2 years of age . Prophylaxis of Invasive Aspergillus and Candida Infections The safety and effectiveness of posaconazole injection have been established for the prophylaxis of invasive Aspergillus and Candida infections in pediatric patients 2 years of age and older who are at high risk of developing these infections due to being severely immunocompromised. Use of posaconazole for these pediatric indications is supported by adequate and well controlled studies of posaconazole in adults and pediatric patients aged 13 years of age and older and additional PK and safety data in pediatric patients 2 years of age and older [see Clinical Pharmacology (12.3) and Clinical studies (14) ] . Treatment of Oropharyngeal Candidiasis, including Refractory to Itraconazole and/or Fluconazole Posaconazole injection is not approved for the treatment of oropharyngeal candidiasis in pediatric patients. The safety and effectiveness of posaconazole have not been established in pediatric patients less than 2 years of age. 8.5 Geriatric Use No overall differences in the safety or effectiveness of posaconazole injection have been observed between geriatric patients and younger adult patients in the clinical trials; therefore, the recommended dosage in geriatric patients is the same as that for younger adult patients. No clinically meaningful differences in posaconazole pharmacokinetics were observed in posaconazole-treated geriatric patients compared to posaconazole-treated younger adult patients during clinical trials [see Clinical Pharmacology (12.3) ] . • Of the 279 patients treated with posaconazole injection in the Posaconazole Injection Study (prophylaxis of invasive Aspergillus and Candida infections in those at high risk of developing these infections due to be ing severly immunocompromised, 52 (19%) patients were > 65 years of age. • Of the 288 patients treated with posaconazole injection in the Aspergillosis Treatment Study, 85 (29%) patients were ≥ 65 years of age. 8.6 Renal Impairment Posaconazole Injection Avoid use of posaconazole injection in patients with eGFR less than 50 mL/minute/1.73 m 2 unless the benefit/risk to the patient justifies its use. The inactive ingredient in posaconazole injection, Betadex Sulfobutyl Ether Sodium (SBECD) is expected to accumulate in patients with reduced renal function. Safety and effectiveness of posaconazole injection have not been established in patients with less than 50 mL/minute/1.73 m 2 . If treatment with posaconazole injection is unavoidable in patients with eGFR less than 50 mL/minute/1.73 m 2 , monitor serum creatinine levels. If serum creatinine increases, consider changing to oral posaconazole therapy. 8.7 Hepatic Impairment No dosage adjustment is recommended for posaconazole injection in patients with mild, moderate, or severe hepatic impairment (Child-Pugh Class A, B, or C, respectively) [see Clinical Pharmacology (12.3) ] . However, a specific hepatic impairment study has not been conducted with the posaconazole injection. 8.8 Sex No adjustment in the dosage of posaconazole is necessary based on sex. 8.9 Race No adjustment in the dosage of posaconazole is necessary based on race. 8.10 Weight Pharmacokinetic modeling suggests that patients who weigh greater than 120 kg may have lower posaconazole plasma drug exposure. Therefore, consider closely monitoring for breakthrough fungal infections particularly when using Noxafil oral suspension in patients weighing greater than 120 kg [see Clinical Pharmacology (12.3) ] ." ], "pregnancy": [ "8.1 Pregnancy Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women.

The no-effect dose for malformations and maternal toxicity in rats was 9 mg/kg, which is 0.7 times the exposure achieved with the 400 mg twice daily oral suspension regimen. No malformations were seen in rabbits dosed during organogenesis (Gestational Days 7 through 19) at doses up to 80 mg/kg (5 times the exposure achieved with the 400 mg twice daily oral suspension regimen). In the rabbit, the no-effect dose was 20 mg/kg, while high doses of 40 mg/kg and 80 mg/kg (3 or 5 times the clinical exposure) caused an increase in resorptions. In rabbits dosed at 80 mg/kg, a reduction in body weight gain of females and a reduction in litter size were seen." ], "risks": [ "Risk Summary Based on findings from animal data, posaconazole may cause fetal harm when administered to pregnant women. Available data for use of posaconazole in pregnant women are insufficient to establish a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, skeletal malformations were observed when posaconazole was dosed orally to pregnant rats during organogenesis at doses ≥ 1.4 times the 400 mg twice daily oral suspension regimen based on steady-state plasma concentrations of posaconazole in healthy volunteers. In pregnant rabbits dosed orally during organogenesis, doses of ≥ 3 times the clinical exposure caused an increase in resorptions (see Data ) .

Posaconazole is highly bound to human plasma proteins (> 98%), predominantly to albumin. Metabolism Posaconazole primarily circulates as the parent compound in plasma. Of the circulating metabolites, the majority are glucuronide conjugates formed via UDP glucuronidation (phase 2 enzymes). Posaconazole does not have any major circulating oxidative (CYP450 mediated) metabolites. The excreted metabolites in urine and feces account for ~ 17% of the administered radiolabeled dose. Posaconazole is a substrate for p-glycoprotein (P-gp) efflux. In vitro studies with human hepatic microsomes and clinical studies indicate that posaconazole is an inhibitor primarily of CYP3A4. Excretion Posaconazole injection is eliminated with a mean terminal half-life (t ½ ) of 27 hours and a total body clearance (CL) of 7.3 L/h. Specific Populations No clinically significant differences in the pharmacokinetics of posaconazole were observed based on age, sex, renal impairment, and indication (prophylaxis or treatment). Race/Ethnicity In a population pharmacokinetic analysis of posaconazole, AUC was found to be 25% higher in Chinese patients relative to patients from other races/ethnicities. This higher exposure is not expected to be clinically relevant given the expected variability in posaconazole exposure [see Use in Specific Populations (8.9) ] . Patients Weighing More Than 120 kg Weight has a clinically significant effect on posaconazole clearance. Relative to 70 kg patients, the C avg is decreased by 25% in patients greater than 120 kg. Patients administered posaconazole weighing more than 120 kg may be at higher risk for lower posaconazole plasma concentrations compared to lower weight patients [see Use in Specific Populations (8.10) ] . Pediatric Patients Prophylaxis of invasive Aspergillus and Candida infections in pediatric patients 2 years of age and older The mean pharmacokinetic parameters after multiple-dose administration of posaconazole injection in neutropenic pediatric patients 2 to less than 18 years of age (Pediatric Study 1) are shown in Table 26. Patients were enrolled into 2 age groups and received posaconazole injection doses at 6 mg/kg (0.6 to 1 times the recommended dose) with a maximum 300 mg dose once daily (twice daily on Day 1) [see Adverse Reactions (6.1) ] .

Drug Interaction Studies Posaconazole is primarily metabolized via UDP glucuronidation (phase 2 enzymes) and is a substrate for p-glycoprotein (P-gp) efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. A summary of drugs studied clinically with the oral suspension or another tablet formulation, which affect posaconazole concentrations, is provided in Table 28. A clinical study in healthy volunteers also indicates that posaconazole is a strong CYP3A4 inhibitor as evidenced by a > 5-fold increase in midazolam AUC. Therefore, plasma concentrations of drugs predominantly metabolized by CYP3A4 may be increased by posaconazole. A summary of the drugs studied clinically, for which plasma concentrations were affected by posaconazole, is provided in Table 31 [see Contraindications (4) and Drug Interactions (7.2) including recommendations ] .

This results in an accumulation of methylated sterol precursors and a depletion of ergosterol within the cell membrane thus weakening the structure and function of the fungal cell membrane. This may be responsible for the antifungal activity of posaconazole. Resistance Clinical isolates of Candida albicans and Candida glabrata with decreased susceptibility to posaconazole were observed in oral swish samples taken during prophylaxis with posaconazole and fluconazole, suggesting a potential for development of resistance. These isolates also showed reduced susceptibility to other azoles, suggesting cross-resistance between azoles. The clinical significance of this finding is not known. Antimicrobial Activity Posaconazole has been shown to be active against most isolates of the following microorganisms, both in vitro and in clinical infections [see Indications and Usage (1) ] .

" ], "mechanism_of_action": [ "12.1 Mechanism of Action Posaconazole is an azole antifungal agent [see Clinical Pharmacology (12.4) ] .", "Mechanism of Action Posaconazole blocks the synthesis of ergosterol, a key component of the fungal cell membrane, through the inhibition of cytochrome P-450 dependent enzyme lanosterol 14α-demethylase responsible for the conversion of lanosterol to ergosterol in the fungal cell membrane. This results in an accumulation of methylated sterol precursors and a depletion of ergosterol within the cell membrane thus weakening the structure and function of the fungal cell membrane. This may be responsible for the antifungal activity of posaconazole." ], "pharmacodynamics": [ "12.2 Pharmacodynamics Exposure Response Relationship: Treatment of Invasive Aspergillosis in Adult and Adolescent Patients Across a range of posaconazole plasma minimum concentrations (C min , range: 244 to 5663 ng/mL) following administration of posaconazole injection and Noxafil delayed-release tablets in adult and pediatric patients aged 14 years and older treated for invasive aspergillosis in Aspergillosis Treatment Study, there was no association between posaconazole C min and treatment efficacy [see Clinical Pharmacology (12.3) and Clinical Studies (14.1) ] .

Posaconazole is highly bound to human plasma proteins (> 98%), predominantly to albumin. Metabolism Posaconazole primarily circulates as the parent compound in plasma. Of the circulating metabolites, the majority are glucuronide conjugates formed via UDP glucuronidation (phase 2 enzymes). Posaconazole does not have any major circulating oxidative (CYP450 mediated) metabolites. The excreted metabolites in urine and feces account for ~ 17% of the administered radiolabeled dose. Posaconazole is a substrate for p-glycoprotein (P-gp) efflux. In vitro studies with human hepatic microsomes and clinical studies indicate that posaconazole is an inhibitor primarily of CYP3A4. Excretion Posaconazole injection is eliminated with a mean terminal half-life (t ½ ) of 27 hours and a total body clearance (CL) of 7.3 L/h. Specific Populations No clinically significant differences in the pharmacokinetics of posaconazole were observed based on age, sex, renal impairment, and indication (prophylaxis or treatment). Race/Ethnicity In a population pharmacokinetic analysis of posaconazole, AUC was found to be 25% higher in Chinese patients relative to patients from other races/ethnicities. This higher exposure is not expected to be clinically relevant given the expected variability in posaconazole exposure [see Use in Specific Populations (8.9) ] . Patients Weighing More Than 120 kg Weight has a clinically significant effect on posaconazole clearance. Relative to 70 kg patients, the C avg is decreased by 25% in patients greater than 120 kg. Patients administered posaconazole weighing more than 120 kg may be at higher risk for lower posaconazole plasma concentrations compared to lower weight patients [see Use in Specific Populations (8.10) ] . Pediatric Patients Prophylaxis of invasive Aspergillus and Candida infections in pediatric patients 2 years of age and older The mean pharmacokinetic parameters after multiple-dose administration of posaconazole injection in neutropenic pediatric patients 2 to less than 18 years of age (Pediatric Study 1) are shown in Table 26. Patients were enrolled into 2 age groups and received posaconazole injection doses at 6 mg/kg (0.6 to 1 times the recommended dose) with a maximum 300 mg dose once daily (twice daily on Day 1) [see Adverse Reactions (6.1) ] .

The population pharmacokinetic analysis of posaconazole in pediatric patients from Pediatric Study 1 suggests that age, sex, renal impairment and ethnicity have no clinically meaningful effect on the pharmacokinetics of posaconazole. Treatment of invasive aspergillosis in pediatric patients 2 years of age and older A total of 31 patients 2 to less than 18 years of age (body weight of ≥ 12 kg) received pediatric dosing based on body weight of posaconazole injection [see Dosage and Administration (2.3) ] . The mean population pharmacokinetic model parameters after multiple dose administration of posaconazole injection in pediatric patients 2 to less than 18 years of age for the treatment of invasive aspergillosis (Pediatric Study 2) are shown in Table 27 [see Adverse Reactions (6.1) ] .

Drug Interaction Studies Posaconazole is primarily metabolized via UDP glucuronidation (phase 2 enzymes) and is a substrate for p-glycoprotein (P-gp) efflux. Therefore, inhibitors or inducers of these clearance pathways may affect posaconazole plasma concentrations. A summary of drugs studied clinically with the oral suspension or another tablet formulation, which affect posaconazole concentrations, is provided in Table 28. A clinical study in healthy volunteers also indicates that posaconazole is a strong CYP3A4 inhibitor as evidenced by a > 5-fold increase in midazolam AUC. Therefore, plasma concentrations of drugs predominantly metabolized by CYP3A4 may be increased by posaconazole. A summary of the drugs studied clinically, for which plasma concentrations were affected by posaconazole, is provided in Table 31 [see Contraindications (4) and Drug Interactions (7.2) including recommendations ] .

Eligible patients had proven, probable, or possible invasive fungal infections per the European Organization for Research and Treatment of Cancer/Mycoses Study Group, EORTC/MSG criteria. Patients were stratified by risk for mortality or poor outcome where high risk included a history of allogeneic bone marrow transplant, liver transplant, or relapsed leukemia undergoing salvage chemotherapy. The median age of patients was 57 years (range 14-91 years), with 27.8% of patients aged ≥65 years; 5 patients were pediatric patients 14-16 years of age, of whom 3 were treated with posaconazole and 2 with voriconazole. The majority of patients were male (59.8%) and white (67.1%). With regard to risk factors for invasive aspergillosis, approximately two-thirds of the patients in the study had a recent history of neutropenia, while approximately 20% with a history of an allogeneic stem cell transplant. Over 80% of subjects in each treatment group had infection limited to the lower respiratory tract (primarily lung), while approximately 11% to 13% also had infection in another organ. Invasive aspergillosis was proven or probable in 58.1% of patients as classified by independent adjudicators blinded to study treatment assignment. At least one Aspergillus species was identified in 21% of the patients; A. fumigatus and A. flavus were the most common pathogens identified. Patients randomized to receive posaconazole were given a dose of 300 mg once daily (twice daily on Day 1) IV or tablet. Patients randomized to receive voriconazole were given a dose of 6 mg/kg twice daily Day 1 followed by 4 mg/kg twice daily IV, or oral 300 mg twice daily Day 1 followed by 200 mg twice daily. The recommended initial route of administration was IV; however, patients could begin oral therapy if clinically stable and able to tolerate oral dosing. The transition from IV to oral therapy occurred when the patient was clinically stable. The protocol recommended duration of therapy was 84 days with a maximum allowed duration of 98 days. Median treatment duration was 67 days for posaconazole patients and 64 days for voriconazole patients. Overall, 55% to 60% of patients began treatment with the IV formulation with a median duration of 9 days for the initial IV dosing. The Intent to Treat (ITT) population included all patients randomized and receiving at least one dose of study treatment. All-cause mortality through Day 42 in the overall population (ITT) was 15.3% for posaconazole patients compared to 20.6% for voriconazole patients for an adjusted treatment difference of -5.3% with a 95% confidence interval of -11.6 to 1.0%. Consistent results were seen in patients with proven or probable invasive aspergillosis per EORTC criteria (see Table 32).
