/FIRST AND FINAL ADD -- PH010 --- BRISTOL-MYERS SQUIBB/ SINGLE-AGENT (VUMON) TENIPOSIDE SUMMARY OF TOXICITY FOR ALL EVALUABLE PEDIATRIC PATIENTS Toxicity Incidence in Evaluable Patients (Pct.) Hematologic Toxicity Myelosuppression, nonspecified 75 Leukopenia (< 3000 WBC/(mu)L) 89 Neutropenia (< 2000 ANC/(mu)L) 95 Thrombocytopenia (<100,000 plt/(mu)L) 85 Anemia 88 Non-Hematologic Toxicity Mucositis 76 Diarrhea 33 Nausea/vomiting 29 Infection 12 Alopecia 9 Bleeding 5 Hypersensitivity reactions 5 Rash 3 Fever 3 Hypotension/Cardiovascular 2 Neurotoxicity <1 Hepatic dysfunction <1 Renal dysfunction <1 Metabolic abnormalities <1 Hematologic Toxicity: Vumon, when used with other chemotherapeutic agents for the treatment of ALL, results in severe myelosuppression. Early onset of profound myelosuppression with delayed recovery can be expected when using the doses and schedules of Vumon necessary for treatment of refractory ALL, since bone marrow hypoplasia is a desired endpoint of therapy. The occurrence of acute non-lymphocytic leukemia (ANLL), with or without a preleukemic phase, has been reported in patients treated with Vumon in combination with other antineoplastic agents. See "PRECAUTIONS" subsection "Carcinogenesis, Mutagenesis, Impairment of fertility". Gastrointestinal Toxicity: Nausea and vomiting are the most common gastrointestinal toxicities, having occurred in 29 percent of evaluable pediatric patients. The severity of this nausea and vomiting is generally mild to moderate. Hypotension: Transient hypotension following rapid intravenous administration has been reported in 2 percent of evaluable pediatric patients. One episode of sudden death, attributed to probable arrhythmia and intractable hypotension, has been reported in an elderly patient receiving Vumon combination therapy for a non-leukemic malignancy. No other cardiac toxicity or electrocardiographic changes have been documented. No delayed hypotension has been noted. Allergic Reactions: Hypersensitivity reactions characterized by chills, fever, tachycardia, flushing, bronchospasm, dyspnea, and blood pressure changes (hypertension or hypotension) have been reported to occur in approximately 5 percent of evaluable pediatric patients receiving intravenous Vumon. The incidence of hypersensitivity reactions to Vumon appears to be increased in patients with brain tumors, and in patients with neuroblastoma1. Central Nervous System: Acute central nervous system depression and hypotension have been observed in patients receiving investigational infusions of high-dose Vumon who were pretreated with antiemetic drugs. The depressant effects of the antiemetic agents and the alcohol content of the Vumon formulation may place patients receiving higher than recommended doses of Vumon at risk for central nervous system depression. Alopecia: Alopecia, sometimes progressing to total baldness, was observed in 9 percent of evaluable pediatric patients who received Vumon as single agent therapy. It was usually reversible. OVERDOSAGE There is no known antidote for Vumon overdosage. The anticipated complications of overdosage are secondary to bone marrow suppression. Treatment should consist of supportive care including blood products and antibiotics as indicated. DOSAGE AND ADMINISTRATION NOTE: Contact of undiluted Vumon (teniposide) for Injection Concentrate with plastic equipment or devices used to prepare solutions for infusion may result in softening or cracking and possible drug product leakage. This effect has not been reported with diluted solutions of Vumon. In order to prevent extraction of the plasticizer DEHP |di(2-ethylhexyl)phtalate~, solutions of Vumon for Injection Concentrate should be prepared in non-DEHP containing LVP containers such as glass or polyolefin plastic bags or containers. Vumon solutions should be administered with non-DEHP containing IV administration sets. In one study, childhood ALL patients failing induction therapy with a cytarabine-containing regimen were treated with the combination of Vumon 165mg/m(superscript)2 and cytarabine 300 mg/m(superscript)2 intravenously, twice weekly for 8-9 doses. In another study, patients with childhood ALL refractory to vincristine/prednisone-containing regimens were treated with the combination of Vumon 250 mg/m(superscript)2 and vincristine 1.5 mg/m(superscript)2 intravenously, weekly for 4-8 weeks and prednisone 40 mg/m(superscript)2 orally x 28 days. Adequate data in patients with hepatic insufficiency and/or renal insufficiency are lacking, but dose adjustments may be necessary for patients with significant renal or hepatic impairment. Preparation and Administration Precautions: Vumon is a cytotoxic anticancer drug and as with other potentially toxic compounds, caution should be exercised in handling and preparing the solution of Vumon. Skin reactions associated with accidental exposure to Vumon may occur. The use of gloves is recommended. If Vumon solution contacts the skin, immediately wash the skin thoroughly with soap and water. If Vumon contacts mucous membranes, the membranes should be flushed thoroughly with water. Preparation for Intravenous Administration: Vumon must be diluted with either 5 percent Dextrose Injection, USP or 0.9 percent Sodium Chloride Injection, USP, to give final teniposide concentrations of 0.1 mg/mL, 0.2 mg/mL, 0.4 mg/mL or 1.0 mg/mL. Solutions prepared in 5 percent Dextrose Injection, USP or 0.9 percent Sodium Chloride Injection, USP at teniposide concentrations of 0.1 mg/mL, 0.2 mg/mL or 0.4 mg/mL are stable at room temperature for up to 24 hours after preparation. Vumon solutions prepared at a final teniposide concentration of 1.0 mg/mL should be administered within 4 hours of preparation to reduce the potential for precipitation. Refrigeration of Vumon solutions is not recommended. Stability and use times are identical in glass and plastic parenteral solution containers. Although solutions are chemically stable under the conditions indicated, precipitation of teniposide may occur at the recommended concentrations, especially if the diluted solution is subjected to more agitation than is recommended to prepare the drug solution for parenteral administration(7). In addition, storage time prior to administration should be minimized and care should be taken to avoid contact of the diluted solution with other drugs or fluids. Parenteral drug products should be inspected visually for particulate matter and discoloration prior to administration whenever solution and container permit. Precipitation has been reported during 24-hour infusions of
Vumon diluted to teniposide concentrations of 0.1 to 0.2 mg/mL, resulting in occlusion of central venous access catheters in several patients(4)(5). Heparin solution can cause precipitation of teniposide, therefore, the administration apparatus should be flushed thoroughly with 5 percent Dextrose Injection or 0.9 percent Sodium Chloride Injection, USP before and after administration of Vumon(5).
Hypotension has been reported following rapid intravenous administration; it is recommended that the Vumon solution be administered over at least a 30 to 60-minute period. Vumon should not be given by rapid intravenous injection. In a 24-hour study under simulated conditions of actual use of the product relative to dilution strength, diluent and administration rates, dilutions at 0.1 to 1.0 mg/mL were chemically stable for at least 24 hours. Data collected for the presence of the extractable DEHP |di(2- ethylhexyl)phtalate~ from PVC containers show that levels increased with time and concentration of the solutions. The data appeared similar for 0.9 percent Sodium Chloride Injection, USP, and 5 percent Dextrose Injection, USP. Consequently, the use of PVC containers is not recommended. Similarly, the use of non-DEHP IV administration sets is recommended. Lipid administration sets or low DEHP containing nitroglycerin sets will keep patients' exposure to DEHP at low levels and are suitable for use. The diluted solutions are chemically and physically compatible with the recommended IV administration sets and LVP containers for up to 24 hours at ambient room temperature and lighting conditions. Because of the potential for precipitation, compatibility with other drugs, infusion materials or IV pumps cannot be assured. Stability: Unopened ampules of Vumon (teniposide) for Injection Concentrate are stable until the date indicated on the package when stored under refrigeration (2 degrees-8 degrees C) in the original package. Freezing does not adversely affect the product. HOW SUPPLIED NDC 0015-3075-19 50 mg/5 mL sterile clear, colorless glass ampules individually packaged in a carton.

Handling and Disposal: Procedures for proper handling and disposal of anticancer drugs should be considered. Several guidelines on this subject have been published (8-14).
