Outcome Measures

Primary Outcome Measures

  1. Part 1 - Number of Participants with Dose Limiting Toxicities (DLTs) during DLT Observation Period [Up to 28 days]

  2. Part 1 - Number of Participants with Treatment Emergent Adverse Events (AEs) and Serious Adverse Events (SAEs) based on Severity during DLT Observation Period [Up to 28 days]

  3. Part 1 - Duration of Treatment Emergent AEs and SAEs (Days) during DLT Observation Period [Up to 28 days]

  4. Part 1 - Percentage of Participants who receive all Planned Doses during DLT Observation Period [Up to 28 days]

  5. Part 1 -Percentage of Participants who require dosage interruptions, dose reductions, and drug discontinuations due to adverse reactions during DLT Observation Period [Up to 28 days]

  6. 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

  1. Part 1 - Area Under Curve (AUC) of GSK4364973 (Metabolite of GSK4524101) [Up to 21 weeks]

  2. Part 1 -Maximum Concentration (Cmax) of GSK4364973 (Metabolite of GSK4524101) [Up to 21 weeks]

  3. Part 1 - Time to Maximum Concentration of GSK4364973 (Metabolite of GSK4524101) [Up to 21 weeks]

  4. Part 1 - Half-life of GSK4364973 (Metabolite of GSK4524101) (Days) [Up to 21 weeks]

  5. Part 1 -Plasma Concentration of Niraparib [Up to 21 weeks]

  6. Part 1 - Number of Participants with TEAEs and SAEs based on Severity beyond DLT Observation Period [Up to approximately 24 weeks]

  7. Part 1 - Duration of TEAEs and SAEs (Days) beyond DLT Observation Period [Up to approximately 24 weeks]

  8. Part 2 - Number of Participants with TEAEs and SAEs based on Severity [Up to approximately 52 weeks]

  9. Part 2 - Duration of Treatment Emergent AEs and SAEs (Days) [Up to approximately 52 weeks]

  10. 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

  11. 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

  12. Part 2 -Maximum Concentration (Cmax) of GSK4364973 (Metabolite of GSK4524101) [Up to 21 weeks]

  13. Part 2 - Minimum Concentration (Cmin) of GSK4364973 (Metabolite of GSK4524101) [Up to 21 weeks]

  14. Part 2 -Plasma Concentration of Niraparib [Up to 21 weeks]
