Primary Outcome Measures
NameTimeMethod
Part 2: To compare progression-free (PFS) survival by independent review committee (IRC) between navtemadlin and placebo50 months

PFS defined as the time from randomization to disease progression by IRC or death, whichever occurs first

Part 1: To determine the navtemadlin Phase 3 dose12 months

Safety review committee (SRC) will determine the navtemadlin Phase 3 dose for Part 2 based on safety data from Part 1

Secondary Outcome Measures
NameTimeMethod
Part 2: To evaluate the treatment effect of navtemadlin on the time to first subsequent treatment (TFST)50 months

TFST defined as the time from randomization to initiation of first subsequent anticancer therapy or death, whichever occurs first

Parts 1 and 2: To determine the pharmacokinetic (PK) profile of navtemadlin1 day

Will determine the time of maximum plasma concentration (Tmax)

Parts 1 and 2: To evaluate the treatment effect of navtemadlin on the disease control rate (DCR)50 months

Best response of complete response (CR), partial response (PR) or stable disease (SD) by IRC/investigator assessment among subjects with PR as best response from prior chemotherapy

Part 1: To evaluate the treatment effect of navtemadlin on PFS by IRC and investigator assessment50 months

PFS defined as the time from randomization to disease progression by IRC/investigator assessment or death, whichever occurs first
