- Patient Information:
Details with Side Effects
HYCAMTIN capsules (topotecan capsules) are indicated for the treatment of relapsed small cell lung cancer in patients with a prior complete or partial response and who are at least 45 days from the end of first-line chemotherapy.
DOSAGE AND ADMINISTRATION
The recommended dose of HYCAMTIN capsules (topotecan capsules) is 2.3 mg/m²/day once daily for 5 consecutive days repeated every 21 days. Round the calculated oral daily dose to the nearest 0.25 mg, and prescribe the minimum number of 1 mg and 0.25 mg capsules. The same number of capsules should be prescribed for each of the 5 dosing days.
HYCAMTIN capsules (topotecan capsules) may be taken with or without food. The capsules must be swallowed whole and must not be chewed, crushed, or divided. If your patient vomits after taking the dose of HYCAMTIN, the patient should not take a replacement dose.
Adjustment of Dose in Special Populations
Renal Function Impairment
No dosage adjustment of HYCAMTIN capsules (topotecan capsules) appears to be required for treating patients with mild renal impairment (CLcr = 50-80 mL/min). A dose adjustment of HYCAMTIN capsules (topotecan capsules) to 1.8 mg/m²/day is predicted to adjust the area under the curve (AUC) to the normal range for patients with moderate renal impairment (CLcr = 3049 mL/min). Insufficient data are available in patients with severe renal impairment (CLcr < 30 mL/min) to provide a dosage recommendation for HYCAMTIN capsules [see Use in Specific Populations].
Dose Modification Guidelines
Patients should not be treated with subsequent courses of HYCAMTIN until neutrophils recover to > 1,000 cells/mm³, platelets recover to > 100,000 cells/mm³, and hemoglobin levels recover to ≥ 9.0 g/dL (with transfusion if necessary).
For patients who experience severe neutropenia (neutrophils < 500 cells/mm³ associated with fever or infection or lasting for 7 days or more) or neutropenia (neutrophils 500 to 1,000 cells/mm³ lasting beyond day 21 of the treatment course), the HYCAMTIN capsules (topotecan capsules) dose should be reduced by 0.4 mg/m²/day for subsequent courses. Doses should be similarly reduced if the platelet count falls below 25,000 cells/mm³.
For patients who experience Grade 3 or 4 diarrhea, the HYCAMTIN capsules (topotecan capsules) dose should be reduced by 0.4 mg/m²/day for subsequent courses [see WARNINGS AND PRECAUTIONS]. Patients with Grade 2 diarrhea may need to follow the same dose modification guidelines.

HYCAMTIN capsules (topotecan capsules) should not be opened or crushed. Direct contact of the capsule contents with the skin or mucous membranes should be avoided.
