Abstract | OBJECTIVES: METHODS: The trial was an open-label phase II study for patients stratified by resistance to either single agent topotecan or to a prior topotecan-containing regimen. Liposomal lurtotecan was delivered at a dose of 2.4 mg/m(2) on Days 1 and 8 of a 21-day cycle. Dose escalations and reductions were allowed based on hematologic toxicity. Patients were evaluated every two cycles for response to liposomal lurtotecan. RESULTS: Twenty-two women were accrued, with 16 women resistant to single agent topotecan and 6 women resistant to topotecan given in combination with a second chemotherapy agent. Hematologic toxicity consisted of mild to moderate thrombocytopenia, anemia, and neutropenia with mild to moderate gastrointestinal toxicity and fatigue. There were no responses, although eight patients had stable disease. CONCLUSIONS: Liposomal lurtotecan at this schedule demonstrates moderate hematologic toxicity and no evidence of clinical activity in a group of heavily pretreated women previously exposed to the topoisomerase I inhibitor topotecan. The study of this agent in alternative patient populations or with alternative schedules is ongoing.
