Primary Outcome Measures
NameTimeMethod
Part 1 - Duration of Treatment Emergent AEs and SAEs (Days) during DLT Observation PeriodUp to 28 days
Part 1 - Percentage of Participants who receive all Planned Doses during DLT Observation PeriodUp to 28 days
Part 1 - Number of Participants with Dose Limiting Toxicities (DLTs) during DLT Observation PeriodUp to 28 days
Part 1 - Number of Participants with Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) based on Severity during DLT Observation PeriodUp to 28 days
Part 1 -Percentage of Participants who require dosage interruptions, dose reductions, and drug discontinuations due to adverse reactions during DLT Observation PeriodUp to 28 days
Part 2 - Confirmed Objective Response Rate (ORR)Up to approximately 52 weeks

ORR is the percentage of participants with an Investigator-assessed confirmed complete response and confirmed partial response to treatment, as assessed by Response Evaluation Criteria in Solid Tumor (RECIST) v1.1

Secondary Outcome Measures
NameTimeMethod
Part 2 -Plasma Concentration of NiraparibUp to 21 weeks
Part 1 - Half-life of GSK4364973 (Metabolite of GSK4524101) (Days)Up to 21 weeks
Part 2 - Progression-free Survival (PFS)Up to approximately 52 weeks

PFS is time from randomization to progressive disease or death from any cause, whichever is earlier, as assessed via RECIST v1.1 by Investigator assessment

Part 1 -Maximum Concentration (Cmax) of GSK4364973 (Metabolite of GSK4524101)Up to 21 weeks
Part 1 - Duration of TEAEs and SAEs (Days) beyond DLT Observation PeriodUp to approximately 24 weeks
Part 2 - Duration of Treatment Emergent AEs and SAEs (Days)Up to approximately 52 weeks
Part 2 - Duration of Response (DOR)Up to approximately 52 weeks

DOR is defined as time from first documented PR or better to disease progression (as assessed by RECIST v1.1 by investigator assessment) or death whichever is earlier for participants who have achieved a CR or PR

Part 1 - Time to Maximum Concentration of GSK4364973 (Metabolite of GSK4524101)Up to 21 weeks
Part 1 - Number of Participants with TEAEs and SAEs based on Severity beyond DLT Observation PeriodUp to approximately 24 weeks
Part 2 - Number of Participants with TEAEs and SAEs based on SeverityUp to approximately 52 weeks
Part 1 - Area Under Curve (AUC) of GSK4364973 (Metabolite of GSK4524101)Up to 21 weeks
Part 1 -Plasma Concentration of NiraparibUp to 21 weeks
Part 2 -Maximum Concentration (Cmax) of GSK4364973 (Metabolite of GSK4524101)Up to 21 weeks
Part 2 - Minimum Concentration (Cmin) of GSK4364973 (Metabolite of GSK4524101)Up to 21 weeks
