We designed a phase I clinical trial of escalating doses of topotecan with CY and carboplatin in combination with autologous hematopoietic SCT (AHSCT) for the treatment of relapsed or persistent platinum sensitive ovarian or primary peritoneal carcinoma. After stem cell collection, 16 patients received topotecan at 1.5, 2.5, 3.5, 4.5 or 6.0mgm2d combined with CY 1.5gm 2d and carboplatin 200mgm2d, all by 4-day continuous infusion. Steady state pharmacokinetics of topotecan and carboplatin were examined. Pre-treatment biopsies were examined for the expression of topoisomerase (topo) I, Ki67 and Bcl-2 family members by immunohistochemistry. One of six patients at a topotecan dose of 4.5mgm2d and two of three patients at 6.0mgm2d had dose-limiting toxicity of grade 3 stomatitis lasting >2 weeks. There was no treatment-related mortality. As topotecan clearance was constant over the dose range examined, topotecan steady state plasma concentrations increased with dose. Median progression-free survival and overall survival were 6.5 months and 2.7 years, respectively. Shorter progression-free survival was observed in tumors with low topo expression (P0.04). Topotecan can safely be dose escalated to 4.5mgm2d in combination with CY, carboplatin and AHSCT. This trial is registered at as NCT00652691.
