( 5.1 ) • Encephalopathy: Monitor for signs and symptoms of CNS toxicity during and after Ifosfamide for Injection treatment. Dose interruption or permanent discontinuation may be required based on individual safety and tolerability. ( 5.2 ) • Nephrotoxicity and Urotoxicity: Monitor signs and symptoms. Monitor serum and urine chemistries. (2.1, 5.3 ) • Cardiotoxicity: Arrhythmias, other ECG changes, and cardiomyopathy can occur and result in death. Cardiotoxicity is dose dependent and the risk is increased in patients with preexisting cardiac, treatment with other cardiotoxic agents, radiation, and renal impairment. ( 5.4 ) • Pulmonary toxicity: Interstitial pneumonitis, pulmonary fibrosis, and pulmonary toxicity with fatal outcomes can occur. Monitor for signs and symptoms of pulmonary toxicity and treat as clinically indicated. ( 5.5 ) • Secondary malignancies can occur. ( 5.6 ) • Veno-occlusive Liver Disease can occur. ( 5.7 ) • Embryo-Fetal Toxicity: Can cause fetal harm. Advise of potential risk to a fetus and use of effective contraception. ( 5.8 , 8.1 , 8.3 ) • Infertility: Can impair male and female reproductive function. ( 5.9 ) • Anaphylactic/anaphylactoid reactions have been reported. ( 5.10 ) 5.1 Myelosuppression Ifosfamide for Injection can cause myelosuppression that results in severe or fatal infections including sepsis or septic shock. Ifosfamide‑induced myelosuppression includes leukopenia, neutropenia, thrombocytopenia (with bleeding events), and anemia. The nadir of the leukocyte count usually occurs during the second week after administration of Ifosfamide for Injection. The risk of myelosuppression is dose‑dependent and increased in patients with reduced renal function, bone marrow metastases, prior radiation, and concomitant or prior therapy with other cytotoxic agents. Monitor complete blood counts, including leukocytes, neutrophils, platelets, and hemoglobin prior to each administration of Ifosfamide for Injection, at appropriate intervals during treatment, and as clinically indicated. Myelosuppression may require dosage delays. Avoid administration of Ifosfamide for Injection to patients with a WBC count below 2000/µL, a platelet count below 50,000/µL, or when signs or symptoms of active infection or severe immunosuppression are present. 5.2 Encephalopathy Ifosfamide for Injection can cause encephalopathy which may be fatal. Signs and symptoms may include confusion, somnolence, coma, hallucination, blurred vision, psychotic behavior, extrapyramidal symptoms, urinary incontinence, and seizures. Risk factors include high ifosfamide dosage, hypoalbuminemia, impaired renal function, poor performance status, bulky abdominal-pelvic disease, nephrotoxic treatments including cisplatin, CNS active drugs, or alcohol use. Signs and symptoms may occur or recur within hours to days after administration of Ifosfamide for Injection. Continue supportive care until complete resolution of CNS signs and symptoms. Monitor for signs and symptoms of encephalopathy during and after Ifosfamide for Injection treatment. Dose interruption or permanent discontinuation may be required based on individual safety and tolerability. Consider methylene blue for treatment of encephalopathy. 5.3 Nephrotoxicity and Urotoxicity Ifosfamide for Injection can cause severe or fatal nephrotoxicity and urotoxicity including glomerular or tubular dysfunction, tubular necrosis, renal parenchymal necrosis, acute renal failure, chronic renal failure, and hemorrhagic cystitis (requiring blood transfusion). Tubular damage may occur up to years after cessation of Ifosfamide for Injection treatment. The risk of nephrotoxicity is increased in patients with renal impairment or reduced nephron reserve. Hemorrhagic cystitis is dose‑dependent and the risk is increased with past or concomitant radiation of the bladder or busulfan treatment. Evaluate glomerular and tubular kidney function before treatment with Ifosfamide for Injection, during Ifosfamide for Injection treatment, and as clinically indicated. Monitor serum and urine chemistries (including phosphorus and potassium) and urinary sediment for the presence of erythrocytes or other signs of nephrotoxicity. Signs and symptoms may include a decrease in glomerular filtration rate, increased serum creatinine, proteinuria, enzymuria, cylindruria, aminoaciduria, phosphaturia, glycosuria, osteomalacia, tubular acidosis, Fanconi syndrome, and syndrome of inappropriate antidiuretic hormone secretion (SIADH). Before starting treatment, exclude or correct any urinary tract obstructions [see Contraindications (4) ]. During or immediately after administration, provide oral or intravenous fluid to force dieresis to reduce the risk of urinary tract toxicity. Administer mesna with Ifosfamide for Injection to reduce the incidence and severity of urotoxicity [see Dosage and Administration (2.1) ]. Obtain a urinalysis prior to each dose of Ifosfamide for Injection. Avoid administration of Ifosfamide for Injection in patients with active urinary tract infections. If microscopic hematuria (greater than 10 RBCs per high power field) is present, then withhold administration of Ifosfamide for Injection until complete resolution. Further administration of Ifosfamide for Injection should be given with vigorous oral or parenteral hydration. Dosage interruption or permanent discontinuation may be required based on individual safety and tolerability. 5.4 Cardiotoxicity Ifosfamide for Injection can cause severe or fatal cardiotoxicity including any of the following: • Supraventricular or ventricular arrhythmias, including atrial/supraventricular tachycardia, atrial fibrillation, pulseless ventricular tachycardia • Decreased QRS voltage and ST-segment or T-wave changes • Toxic cardiomyopathy leading to heart failure with congestion and hypotension • Pericardial effusion, fibrinous pericarditis, and epicardial fibrosis Cardiotoxic effects are dose‑dependent and the risk is increased in patients with cardiac disease, prior or concomitant treatment with other cardiotoxic agents, radiation of the cardiac region, and renal impairment. 5.5 Pulmonary Toxicity Ifosfamide for Injection can cause severe or fatal pulmonary toxicities including interstitial pneumonitis, pulmonary fibrosis, and respiratory failure. Monitor for signs and symptoms of pulmonary toxicity and treat as clinically indicated. 5.6 Secondary Malignancies The incidence of secondary malignancies is increased in patients treated with Ifosfamide for Injection-containing regimens. Cases of myelodysplastic syndrome, acute leukemias, lymphomas, thyroid cancers, and sarcomas have occurred and may develop several years after chemotherapy has been discontinued. 5.7 Veno-occlusive Liver Disease Veno-occlusive liver disease has been reported with chemotherapy that included ifosfamide. 5.8 Embryo-Fetal Toxicity Based on mechanism of action and human and animal data, Ifosfamide for Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) , Clinical Pharmacology (12.1) and Nonclinical Toxicology (13.1) ]. Fetal growth retardation and neonatal anemia have been reported following exposure to ifosfamide‑containing chemotherapy regimens during pregnancy. Ifosfamide is genotoxic and mutagenic in male and female germ cells. Embryotoxic and teratogenic effects have been observed in mice, rats and rabbits at doses 0.05 to 0.075 times the human dose. Advise pregnant women and females of reproductive potential of the potential risk to the fetus [see Use in Specific Populations (8.1) ]. Verify the pregnancy status of females of reproductive potential prior to initiation of Ifosfamide for Injection. Advise females of reproductive potential to use effective contraception during treatment with Ifosfamide for Injection and for up to 12 months after completion of therapy. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with Ifosfamide for Injection and for 6 months after completion of therapy [see Use in Specific Populations (8.1 , 8.3) ]. 5.9 Infertility Male and female reproductive function and fertility may be impaired in patients treated with Ifosfamide for Injection. Ifosfamide interferes with oogenesis and spermatogenesis. Amenorrhea, azoospermia; and sterility in both sexes have been reported. Development of sterility appears to depend on the dose of ifosfamide, duration of therapy, and state of gonadal function at the time of treatment. Sterility may be irreversible in some patients. Advise patients on the potential risks for infertility [see Use in Specific Populations (8.3 and 8.4) ]. 5.10 Anaphylactic/Anaphylactoid Reactions and Cross-sensitivity Anaphylactic/anaphylactoid reactions have been reported in association with ifosfamide. Cross-sensitivity between oxazaphosphorine cytotoxic agents has been reported. 5.11 Impairment of Wound Healing Ifosfamide may interfere with normal wound healing." ], "adverse_reactions": [ "6 ADVERSE REACTIONS The most common (≥ 10%) adverse reactions were alopecia, nausea/vomiting, hematuria, leukopenia, anemia, CNS toxicity, infection.

( 8.2 ) • Renal impairment: Closely monitor for adverse reactions and consider dosage modifications. ( 8.6 ) 8.1 Pregnancy Risk Summary Based on mechanism of action [see Clinical Pharmacology (12.1) ] , and human and animal data (see Data) , Ifosfamide for Injection can cause fetal harm when administered to a pregnant woman. Fetal growth retardation and neonatal anemia have been reported following exposure to ifosfamide‑containing chemotherapy regimens during pregnancy. 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 Animal studies indicate that ifosfamide is capable of causing gene mutations and chromosomal damage in vivo . In pregnant mice, resorptions increased and anomalies were present at day 19 after a 30 mg/m 2 dose of ifosfamide was administered on day 11 of gestation. Embryo-lethal effects were observed in rats following the administration of 54 mg/m 2 doses of ifosfamide from the 6th through the 15th day of gestation and embryotoxic effects were apparent after dams received 18 mg/m 2 doses over the same dosing period. Ifosfamide is embryotoxic to rabbits receiving 88 mg/m 2 /day doses from the 6th through the 18th day after mating. The number of anomalies was also significantly increased over the control group. 8.2 Lactation Risk Summary Ifosfamide is excreted in breast milk. Because of the potential for serious adverse events, and the tumorigenicity shown for ifosfamide in animal studies, advise women not to breastfeed during treatment with Ifosfamide for Injection and for one week after the last dose. 8.3 Females and Males of Reproductive Potential Ifosfamide for Injection can cause fetal harm when administered to a pregnant woman [see Use in Specific Populations (8.1) ] . Pregnancy Testing Verify pregnancy status in females of reproductive potential prior to initiating Ifosfamide for Injection [see Use in Specific Populations (8.1) ] . Contraception Females Advise female patients of reproductive potential to use effective contraception during treatment with Ifosfamide for Injection and for 12 months after the last dose. Males Advise males with female sexual partners of reproductive potential to use effective contraception during treatment with Ifosfamide for Injection and for 6 months after the last dose [see Nonclinical Toxicology (13.1) ] . Infertility Females Amenorrhea has been reported in patients treated with ifosfamide. The risk of permanent chemotherapy induced amenorrhea increases with age. Males Men treated with ifosfamide may develop oligospermia or azoospermia. Azoospermia may be reversible in some patients, though the reversibility may not occur for several years after cessation of therapy. Sexual function and libido are generally unimpaired in these patients. Some degree of testicular atrophy may occur. Patients treated with ifosfamide have subsequently fathered children. Females and Males Based on animal studies, Ifosfamide for Injection may impair fertility in females and males of reproductive potential. The reversibility of these effects is unknown [see Nonclinical Toxicology (13.1) ] . 8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients. Renal rickets and growth retardation in pediatric patients treated with ifosfamide have been reported. Ifosfamide for Injection may cause temporary or permanent infertility in prepubertal girls or in females of child-bearing potential and may have an increased risk of developing premature menopause. Ifosfamide for Injection may cause abnormal secondary sexual characteristic development in prepubertal males. Sterility, azoospermia, and testicular atrophy have been reported in male patients. Azoospermia may be reversible in some patients, but may not occur for several years after cessation of Ifosfamide for Injection therapy. 8.5 Geriatric Use Clinical studies of Ifosfamide for Injection did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger subjects. A study of patients 40 to 71 years of age indicated that elimination half-life appears to increase with advancing age [see Pharmacokinetics (12.3) ] . This apparent increase in half-life appeared to be related to increases in volume of distribution of ifosfamide with age. No significant changes in total plasma clearance or renal or non-renal clearance with age were reported. Ifosfamide and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, closely monitor for adverse reactions and monitor renal function as clinically indicated. 8.6 Use in Patients with Renal Impairment Ifosfamide and its metabolites are known to be excreted by the kidneys and may accumulate in plasma with decreased renal function. Closely monitor patients with renal impairment for adverse reactions and consider dosage modifications. Ifosfamide and its metabolites are dialyzable. 8.7 Use in Patients with Hepatic Impairment Ifosfamide is extensively metabolized in the liver and forms both efficacious and toxic metabolites.

In pregnant mice, resorptions increased and anomalies were present at day 19 after a 30 mg/m 2 dose of ifosfamide was administered on day 11 of gestation. Embryo-lethal effects were observed in rats following the administration of 54 mg/m 2 doses of ifosfamide from the 6th through the 15th day of gestation and embryotoxic effects were apparent after dams received 18 mg/m 2 doses over the same dosing period. Ifosfamide is embryotoxic to rabbits receiving 88 mg/m 2 /day doses from the 6th through the 18th day after mating. The number of anomalies was also significantly increased over the control group." ], "pediatric_use": [ "8.4 Pediatric Use Safety and effectiveness have not been established in pediatric patients. Renal rickets and growth retardation in pediatric patients treated with ifosfamide have been reported. Ifosfamide for Injection may cause temporary or permanent infertility in prepubertal girls or in females of child-bearing potential and may have an increased risk of developing premature menopause. Ifosfamide for Injection may cause abnormal secondary sexual characteristic development in prepubertal males. Sterility, azoospermia, and testicular atrophy have been reported in male patients. Azoospermia may be reversible in some patients, but may not occur for several years after cessation of Ifosfamide for Injection therapy." ], "geriatric_use": [ "8.5 Geriatric Use Clinical studies of Ifosfamide for Injection did not include sufficient numbers of patients aged 65 and over to determine whether they respond differently from younger subjects. A study of patients 40 to 71 years of age indicated that elimination half-life appears to increase with advancing age [see Pharmacokinetics (12.3) ] . This apparent increase in half-life appeared to be related to increases in volume of distribution of ifosfamide with age. No significant changes in total plasma clearance or renal or non-renal clearance with age were reported. Ifosfamide and its metabolites are known to be substantially excreted by the kidney, and the risk of toxic reactions to this drug may be greater in patients with impaired renal function. Because elderly patients are more likely to have decreased renal function, closely monitor for adverse reactions and monitor renal function as clinically indicated." ], "overdosage": [ "10 OVERDOSAGE No specific antidote for Ifosfamide for Injection is known. Patients who receive an overdose should be closely monitored for the development of toxicities. Serious consequences of overdosage include manifestations of dose-dependent toxicities such as CNS toxicity, nephrotoxicity, myelosuppression, and mucositis [see Warnings and Precautions (5) ]. Management of overdosage would include general supportive measures to sustain the patient through any period of toxicity that might occur, including appropriate state-of-the-art treatment for any concurrent infection, myelosuppression, or other toxicity. Ifosfamide as well as ifosfamide metabolites are dialyzable. Cystitis prophylaxis with mesna may be helpful in preventing or limiting urotoxic effects with overdose." ], "description": [ "11 DESCRIPTION Ifosfamide for Injection (ifosfamide for injection, USP) single-dose vials for constitution and administration by intravenous infusion each contain 1 gram or 3 grams of sterile ifosfamide. Ifosfamide is a alkylating drug chemically related to the nitrogen mustards and a synthetic analog of cyclophosphamide. Ifosfamide is 3-(2-chloroethyl)-2-[(2-chloroethyl)amino]tetrahydro-2H-1,3,2-oxazaphosphorine 2-oxide. The molecular formula is C 7 H 15 Cl 2 N 2 O 2 P and its molecular weight is 261.1. Ifosfamide is a white crystalline powder soluble in water. There are no excipients in the formulation. Each vial contains 1 gram or 3 grams of sterile ifosfamide alone. Its structural formula is: Structural Formula" ], "clinical_pharmacology": [ "12 CLINICAL PHARMACOLOGY 12.1 Mechanism of Action Ifosfamide is a prodrug that requires metabolic activation by hepatic cytochrome P450 isoenzymes to exert its cytotoxic activity. Activation occurs by hydroxylation at the ring carbon atom forming the unstable intermediate 4‑hydroxyifosfamide and its ring-opened aldo tautomer, which decomposes to yield the cytotoxic and urotoxic compound acrolein and an alkylating isophosphoramide mustard isophosphoramide mustard. The exact mechanism of action of ifosfamide has not been determined, but its cytotoxic action is primarily through DNA crosslinks caused by alkylation by the isophosphoramide mustard at guanine N-7 positions. The formation of inter- and intra-strand cross-links in the DNA results in cell death. 12.3 Pharmacokinetics Ifosfamide exhibits dose-dependent pharmacokinetics in humans. At single doses of 3.8 to 5.0 g/m 2 , the plasma concentrations decay biphasically and the mean terminal elimination half-life is about 15 hours. At doses of 1.6 to 2.4 g/m 2 /day, the plasma decay is monoexponential and the terminal elimination half-life is about 7 hours. Ifosfamide exhibits time-dependent pharmacokinetics in humans. Following intravenous administration of 1.5 g/m 2 over 0.5 hour once daily for 5 days to 15 patients with neoplastic disease, a decrease in the median elimination half-life from 7.2 hour on Day 1 to 4.6 hours on Day 5 occurred with a concomitant increase in the median clearance from 66 mL/min on Day 1 to 115 mL/min on Day 5. There was no significant change in the volume of distribution on Day 5 compared with Day 1. Distribution Ifosfamide volume of distribution (Vd) approximates the total body water volume, suggesting that distribution takes place with minimal tissue binding. Following intravenous administration of 1.5 g/m 2 over 0.5 hour once daily for 5 days to 15 patients with neoplastic disease, the median Vd of ifosfamide was 0.64 L/kg on Day 1 and 0.72 L/kg on Day 5. Ifosfamide shows little plasma protein binding. Ifosfamide and its active metabolites are extensively bound by red blood cells. Ifosfamide is not a substrate for P-glycoprotein. Metabolism Ifosfamide is extensively metabolized in humans through two metabolic pathways: ring oxidation (“activation”) to form the active metabolite, 4-hydroxy-ifosfamide and side-chain oxidation to form the inactive metabolites, 3-dechloro-ethylifosfamide or 2-dechloroethylifosfamide with liberation of the toxic metabolite, chloroacetaldehyde. Small quantities (nmol/mL) of ifosfamide mustard and 4‑hydroxyifosfamide are detectable in human plasma. Metabolism of ifosfamide is required for the generation of the biologically active species and while metabolism is extensive, it is also quite variable among patients. Excretion After administration of doses of 5 g/m 2 of 14 C-labeled ifosfamide, from 70% to 86% of the dosed radioactivity was recovered in urine as metabolites, with about 61% of the dose excreted as parent compound. At doses of 1.6 to 2.4 g/m 2 only 12% to 18% of the dose was excreted in the urine as unchanged drug within 72 hours. Two different dechloroethylated derivatives of ifosfamide, 4-carboxyifosfamide, thiodiacetic acid and cysteine conjugates of chloroacetic acid have been identified as the major urinary metabolites of ifosfamide in humans and only small amounts of 4‑hydroxyifosfamide and acrolein are present. Specific Populations Pediatric Patients Population PK analysis was performed on plasma data from 32 pediatric patients various malignant diseases aged between 1 and 18 years. Patients received a total of 45 courses of ifosfamide at doses of 1.2, 2.0 and 3.0 g/m 2 given intravenously over 1 or 3 hours on 1, 2, or 3 days. The mean±standard error population estimates for the initial clearance and volume of distribution of ifosfamide were 2.4±0.33 L/h/m 2 and 21±1.6 L/m 2 with an interindividual variability of 43% and 32%, respectively. Effect of Age A study of 20 patients between 40 to 71 years of age receiving 1.5 g/m 2 of ifosfamide daily for 3 or 5 days indicated that elimination half‑life appears to increase with age. The elimination half‑life increase appeared to be related to the increase in ifosfamide volume of distribution with age.

The selection of etoposide or vinblastine (“V” in the VIP regimen) was guided by the therapeutic effect achieved with prior regimens. The contribution of ifosfamide to the VIP combination was determined in patients treated with cisplatin-etoposide prior to ifosfamide-cisplatin-etoposide or those who received cisplatin-vinblastine prior to ifosfamide-cisplatin-vinblastine. A total of 59 patients received a third-line salvage regimen which consisted of ifosfamide 1.2 g/m 2 /day intravenously on days 1 to 5, cisplatin 20 mg/m 2 /day intravenously on days 1 to 5, and either etoposide 75 mg/m 2 /day intravenously on days 1 to 5 or vinblastine 0.22 mg/kg intravenously on day 1. Efficacy results with the VIP regimen were compared to data pooled from six single agent phase II trials conducted between August 1980 and October 1985 including a total of 90 patients of whom 65 were eligible as controls of this study. Twenty-three patients in the VIP regimen became free of disease with VIP alone or VIP plus surgery, whereas a single patient in the historical control group achieved complete response. The median survival time exceeded two years in the VIP group versus less than one year in the control group. Performance status ≥ 80, embryonal carcinoma and minimal disease were favorable prognostic factors for survival. In all prognostic categories, the difference between VIP and historical controls remained highly significant. Table 3: Efficacy Results Number.

Patients were selected for remaining cisplatin sensitivity because they had previously responded to a cisplatin containing regimen and had not progressed while on the cisplatin containing regimen or within 3 weeks of stopping it. Patients served as their own control based on the premise that long term complete responses could not be achieved by retreatment with a regimen to which they had previously responded and subsequently relapsed.
