Boxed warning. MYELOSUPPRESSION Topotecan can cause severe myelosuppression. Administer first cycle only to patients with baseline neutrophil counts of greater than or equal to 1,500/mm 3 and platelet counts greater than or equal to 100,000/mm 3. Monitor blood cell counts. WARNING: MYELOSUPPRESSION See full prescribing information for complete boxed warning. Topotecan can cause severe myelosuppression. Administer first cycle only to patients with baseline neutrophil counts greater than or equal to 1,500/mm 3 and platelet count greater than or equal to 100,000/mm 3. Monitor blood cell counts. Interstitial lung disease (ILD): Fatal cases have occurred. Permanently discontinue if ILD confirmed. Extravasation and tissue injury: Severe cases have occurred. If extravasation occurs, immediately stop administration and institute recommended management procedures. Embryo-fetal toxicity: Can cause fetal harm. Advise women of potential risk to the fetus. Myelosuppression Topotecan can cause severe myelosuppression. Grade 4 neutropenia occurred in 78% of 879 patients, with a median duration of 7 days and was most common during Cycle 1 (58% of patients). Grade 4 neutropenia associated with infection occurred in 13% and febrile neutropenia occurred in 5%. Sepsis occurred in 4% and was fatal in 1%. Grade 4 thrombocytopenia occurred in 27%, with a median duration of 5 days. Grade 3 or 4 anemia occurred in 37% of patients. Topotecan can cause fatal typhlitis (neutropenic enterocolitis). Consider the possibility of typhlitis in patients presenting with fever, neutropenia, and abdominal pain. Administer the first cycle of Topotecan Injection only to patients with a baseline neutrophil count of greater than or equal to 1,500/mm 3 and a platelet count greater than or equal to 100,000/mm 3. Monitor blood counts frequently during treatment. Withhold and reduce dose of Topotecan Injection based on neutrophil counts, platelet counts and hemoglobin levels. Interstitial Lung Disease Interstitial lung disease (ILD), including fatalities, has occurred with Topotecan. Underlying risk factors include history of ILD, pulmonary fibrosis, lung cancer, thoracic radiation, and use of pneumotoxic drugs and/or colony stimulating factors. Monitor patients for pulmonary symptoms indicative of ILD (e.g., cough, fever, dyspnea, and/or hypoxia), and discontinue Topotecan Injection if a new diagnosis of ILD is confirmed. Extravasation and Tissue Injury Extravasation with Topotecan has been observed; severe cases have been reported. If signs or symptoms of extravasation occur, immediately stop administration of Topotecan Injection and institute recommended management procedures. Abridged from the full prescribing information.

The following serious adverse reactions are described elsewhere in the labeling: Myelosuppression Interstitial Lung Disease Extravasation and Tissue Injury The most common Grade 3 or 4 hematologic adverse reactions (incidence >5%) were: neutropenia, anemia, thrombocytopenia, and febrile neutropenia. The most common non-hematologic adverse reactions (incidence >5%) (all grades) were asthenia, dyspnea, nausea, pneumonia, abdominal pain, and fatigue. 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 with rates in the clinical trials of another drug and may not reflect the rates observed in practice. The data in Warnings and Precautions reflect exposure to Topotecan from 8 trials in which 879 patients with small cell lung cancer (SCLC) and other solid tumors received Topotecan 1.5 mg/m 2 by intravenous infusion daily for 5 consecutive days, starting on Day 1 of a 21-day cycle. Small Cell Lung Cancer (SCLC) The safety of Topotecan was evaluated in randomized, comparative trial in patients with recurrent or progressive SCLC (Study 090). Table 1 shows the Grade 3 or 4 hematologic and non-hematologic adverse reactions in patients with SCLC. Table 1. Adverse Reactions Occurring in ≥5% of Patients with Small Cell Lung Cancer in Study 090 Adverse Reactions Topotecan (n = 107) CAV CAV = cyclophosphamide, doxorubicin and vincristine. (n = 104) Grade 3–4 (%) Grade 3–4 (%) Hematologic Grade 4 neutropenia (< 500/mm 3 ) 70 72 Grade 3 or 4 anemia (Hgb < 8 g/dL) 42 20 Grade 4 thrombocytopenia (< 25,000/mm 3 ) 29 5 Febrile neutropenia 28 26 Non-Hematologic Respiratory, thoracic, and mediastinal Dyspnea 9 14 Pneumonia 8 6 General and administrative site conditions Asthenia 9 7 Fatigue 6 10 Pain Pain includes body pain, skeletal pain, and back pain. 5 7 Gastrointestinal Nausea 8 6 Abdominal pain 6 4 Infections Sepsis Death related to sepsis occurred in 3% of patients receiving Topotecan and 1% of patients receiving CAV. 5 5 Hepatobiliary Disorders Based on 879 patients with small cell lung cancer or another solid tumor who were treated with Topotecan, Grade 3 or 4 elevated aspartate (AST) or alanine transaminase (ALT) occurred in 4% and Grade 3 or 4 elevated bilirubin occurred in less than 2% of patients. Postmarketing Experience The following reactions have been identified during postapproval use of Topotecan. Abridged from the full prescribing information.
