Advisory information

contraindications
4 CONTRAINDICATIONS ETOPOPHOS is contraindicated in patients with a history of a severe hypersensitivity reaction to etoposide products [see Warnings and Precautions (5.3)]. Hypersensitivity to etoposide products. (4, 5.3)
Adverse reactions
6 ADVERSE REACTIONS The following serious adverse reactions are described elsewhere in the labeling: Myelosuppression [see Warnings and Precautions (5.1)] Secondary leukemias [see Warnings and Precautions (5.2)] Hypersensitivity reactions [see Warnings and Precautions (5.3)] Most common adverse reaction is neutropenia. (6) To report SUSPECTED ADVERSE REACTIONS, contact Bristol-Myers Squibb at 1-800-721-5072 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates, observed in the clinical trials of a drug, cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. ETOPOPHOS has been used as a single agent in clinical studies involving 206 patients with a variety of malignancies (including one non-Hodgkin’s lymphoma) and in combination with cisplatin in 60 patients with small cell lung cancer. The most common adverse reaction was neutropenia. Other Important Adverse Reactions Gastrointestinal Toxicity Nausea and vomiting are the major gastrointestinal toxicities. The severity of nausea and vomiting is generally mild to moderate, with treatment discontinuation required in 1% of patients. Nausea and vomiting are managed with standard antiemetic therapy. Other Toxicities Other clinically important adverse reactions in clinical trials were: Gastrointestinal: abdominal pain, constipation, dysphagia General: fever Ocular: transient cortical blindness, optic neuritis Respiratory: interstitial pneumonitis/pulmonary fibrosis Skin: pigmentation, radiation recall dermatitis, Stevens-Johnson syndrome, and toxic epidermal necrolysis Neurologic: seizure, aftertaste Hepatobiliary disorder: hepatotoxicity 6.2 Post-Marketing Experience The following adverse reactions have been identified during post-approval use of ETOPOPHOS. 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. Extravasation Extravasation, resulting in local soft tissue toxicity, was identified in postmarketing reports. Extravasation of ETOPOPHOS may result in swelling, pain, cellulitis, and necrosis including skin necrosis.

Usage information

(2.2) Do not give by bolus injection. (2.4) Renal impairment: Reduce the recommended dose to 75% in patients with creatinine clearance 15 to 50 mL/min. (2.3) 2.1 Refractory Testicular Tumors The recommended dose of ETOPOPHOS is: 50 to 100 mg/m2 per day administered intravenously over 5 minutes to 3.5 hours on days 1 through 5 of each 21-day (or 28-day cycle), or 100 mg/m2 administered intravenously over 5 minutes to 3.5 hours on days 1, 3, and 5 of each 21-day (or 28-day cycle). 2.2 Small Cell Lung Cancer The recommended dose of ETOPOPHOS is: • 35 mg/m2 per day administered intravenously over 5 minutes to 3.5 hours for 4 days, or • 50 mg/m2 per day administered intravenously over 5 minutes to 3.5 hours for 5 days. 2.3 Dosage Modification In patients with a creatinine clearance (CLcr) 15-50 mL/min, administer 75% of the recommended dose. Data are not available in patients with CLcr less than 15 mL/min. Consider further dose reduction in these patients. 2.4 Preparation and Administration Preparation Reconstitute with Sterile Water for Injection, USP; 5% Dextrose Injection, USP; 0.9% Sodium Chloride Injection, USP; Bacteriostatic Water for Injection with Benzyl Alcohol; or Bacteriostatic Sodium Chloride for Injection with Benzyl Alcohol, using the quantity of diluent shown below: Vial Strength Volume of Diluent Final Concentration 100 mg 5 mL 20 mg/mL 10 mL 10 mg/mL Following reconstitution, ETOPOPHOS can be further diluted to concentrations as low as 0.1 mg/mL with either 5% Dextrose Injection, USP, or 0.9% Sodium Chloride Injection, USP. Inspect parenteral drug products visually for particulate matter and discoloration prior to administration whenever solution and container permit. Storage After reconstitution, store under the following conditions: Refrigerated 2° to 8°C (36° to 46°F) for 7 days; Room temperature at 20° to 25°C (68° to 77°F) for 24 hours following reconstitution with Sterile Water for Injection, USP, 5% Dextrose Injection, USP, or 0.9% Sodium Chloride Injection, USP; Room temperature 20° to 25°C (68° to 77°F) for 48 hours following reconstitution with Bacteriostatic Water for Injection with benzyl alcohol or Bacteriostatic Sodium Chloride for Injection with benzyl alcohol. Reconstituted ETOPOPHOS solutions further diluted as directed can be stored under refrigeration 2° to 8°C (36° to 46°F) or at room temperature 20° to 25°C (68° to 77°F) for 24 hours. Administration DO NOT GIVE ETOPOPHOS BY BOLUS INTRAVENOUS INJECTION. ETOPOPHOS solutions may be administered at infusion rates up to 3.5 hours. Extravasation of ETOPOPHOS may result in swelling, pain, cellulitis, and necrosis including skin necrosis. ETOPOPHOS is a cytotoxic drug. Follow applicable special handling and disposal procedures.1 To minimize the risk of dermal exposure, use of gloves is recommended. If dermal contact occurs, immediately and thoroughly wash areas of skin contact with soap and water and flush mucosa with water.
Use in special populations
8 USE IN SPECIFIC POPULATION Lactation: Do not breastfeed. (8.2) 8.1 Pregnancy Risk Summary Based on animal data and its mechanism of action, ETOPOPHOS can cause fetal harm when administered to a pregnant woman. Etoposide, the active moiety of etoposide phosphate is teratogenic in mice and rats [see Data]. Advise pregnant women of the potential hazard to a fetus. Advise women of childbearing potential to avoid becoming pregnant. 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 In rats, an intravenous etoposide dose of 0.4 mg/kg/day (about 0.05 times of the 50 mg/m2 human dose based on body surface area [BSA]) during organogenesis caused maternal toxicity, embryotoxicity, and teratogenicity (skeletal abnormalities, exencephaly, encephalocele, and anophthalmia); higher doses of 1.2 and 3.6 mg/kg/day (about 0.14 and 0.5 times the 50 mg/m2 human dose based on BSA) resulted in 90% and 100% embryonic resorptions. In mice, a single etoposide dose of 1.0 mg/kg (approximately 0.06 times the 50 mg/m2 human dose based on BSA) administered intraperitoneally on days 6, 7, or 8 of gestation caused embryotoxicity, cranial abnormalities, and major skeletal malformations. An intraperitoneal dose of 1.5 mg/kg (about 0.1 times the 50 mg/m2 human based on BSA) on day 7 of gestation caused an increase in the incidence of intrauterine death and fetal malformations and a significant decrease in the average fetal body weight [see Nonclinical Toxicology (13.1)]. 8.2 Lactation There is no information regarding the presence of etoposide in human milk or its effects on breastfed infant milk production. Because of the potential for serious adverse reactions in nursing infants from ETOPOPHOS, advise women not to breastfeed during treatment with ETOPOPHOS. 8.3 Females and Males of Reproductive Potential Contraception Females Advise females of reproductive potential to use effective contraception during treatment with ETOPOPHOS and for 6 months after the final dose. Males ETOPOPHOS may damage spermatozoa and testicular tissue, resulting in possible genetic fetal abnormalities. Males with female sexual partners of reproductive potential should use effective contraception during treatment with ETOPOPHOS and for 4 months after the final dose. Infertility Females In females of reproductive potential, ETOPOPHOS may cause infertility and result in amenorrhea. Premature menopause can occur with ETOPOPHOS. Recovery of menses and ovulation is related to age at treatment. Males In male patients, ETOPOPHOS may result in oligospermia, azoospermia, and permanent loss of fertility. Sperm counts have been reported to return to normal levels in some men, and in some cases, have occurred several years after the end of therapy [See Nonclinical Toxicology (13.1)]. 8.4 Pediatric Use Safety and effectiveness in pediatric patients have not been established. 8.5 Geriatric Use Clinical studies of etoposide did not include sufficient numbers (n=71) of patients aged 65 years and over to determine whether they respond differently from younger patients. Other reported clinical experience has not identified differences in responses between elderly and younger patients.
