Clinical Trial Summary

This is an open-label, single-arm, Phase 1b/2 study designed to evaluate the safety, tolerability, and preliminary efficacy of milademetan in combination with atezolizumab in patients with advanced solid tumors with confirmed homozygous CDKN2A loss and WT TP53 who have progressed on or are refractory to prior PD-1/PD-L1 inhibitor therapy and who, in the opinion of the Investigator, are unlikely to tolerate or derive clinically meaningful benefit from other therapy. This study will determine the recommended dose of milademetan when given in combination with atezolizumab (the combination RP2D) using a dose de-escalation safety assessment cohort (Phase 1b). Following identification of the combination RP2D, the safety profile and preliminary anti-tumor activity of the combination RP2D will be evaluated in a larger population in a dose expansion cohort (Phase 2).


Clinical Trial Description

Up to 30 patients will be enrolled, 3 to 18 patients in the safety assessment cohort and 12 to 27 patients in the dose expansion cohort. ;
