Experimental: DS-3201b and Irinotecan
The first part of this study is a phase I trial to assess the safety and tolerability of DS-3201b in combination with fixed-dose irinotecan. The second part of this study will be an open label, single-arm phase II study of DS-3201b at the established recommended phase II dose (RP2D) in combination with fixed-dose irinotecan. Dose-Escalation, which enrolled a total of 12 patients at MSK, is completed. Phase 1 of this study determined that the highest and safest dose of DS-3201b in patients was 100 mg daily.
100 mg daily
Irinotecan 125 mg/m^2 intravenously on days 1 and 8 every 3 weeks in a 21-day cycle.
- maximum tolerated dose (MTD) (Phase l) [ Time Frame: 1 year ]Will employ a standard 3-by-3 dose-escalation phase I study design to investigate the maximum tolerated dose (MTD) of DS-3201b in combination with fixed dose irinotecan. The study population for Phase I dose-escalation will include only patients who complete at least 1 full cycle of treatment (including the initial 7-day safety run-in and the complete 21-days of Cycle 1); only these patients will be considered evaluable for DLT and determination of the MTD.
- objective response rate (ORR) (Phase II) [ Time Frame: 1 year ]The Response Evaluation Criteria in Solid Tumors Group (RECIST v1.1) criteria will be used to evaluate the response to treatment
