Study Summary

This study will test the safety of the study drug, DS-3201b, given in combination with irinotecan to people who have recurrent small cell lung cancer (SCLC).

Primary Outcome

Will employ a standard 3-by-3 dose-escalation phase I study design to investigate the maximum tolerated dose (MTD) of DS-3201b/valemetostat 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.
