Participants with HRRm or HRD-positive advanced cancer will receive oral olaparib, 300 mg twice daily (BID).
Olaparib 300 mg administered BID as two, 150 mg oral tablets.
- Objective Response Rate (ORR) [ Time Frame: Up to 53 months ]ORR is defined as the percentage of participants who achieve a confirmed complete response ([CR]; disappearance of all target lesions) or partial response ([PR]: ≥30% decrease in the sum of diameters of target lesions) as assessed by blinded independent central review (BICR) per Response Evaluation Criteria in Solid Tumors 1.1 (RECIST 1.1). For participants with prostate cancer, ORR will be based on Prostate Cancer Working Group (PCWG)-modified RECIST 1.1 as assessed by BICR.
- Duration of Response (DOR) [ Time Frame: Up to 53 months ]DOR is defined as the time from first documented evidence of CR or PR until the first documented sign of disease progression or death due to any cause, whichever occurs first. DOR will be assessed by BICR according to either RECIST 1.1 or PCWG-modified RECIST 1.1 for participants with prostate cancer.
- Overall Survival (OS) [ Time Frame: Up to 53 months ]OS is defined as the time from the date of the first dose to the date of death due to any cause.
- Progression Free Survival (PFS) [ Time Frame: Up to 53 months ]PFS is defined as the time from the date of the first dose to either: 1) the first documented disease progression as assessed either by BICR according to RECIST 1.1 or PCWG-modified RECIST 1.1 for participants with prostate cancer; or 2) death due to any cause, whichever occurs first.
- Number of Participants Experiencing an Adverse Event (AE) [ Time Frame: Up to 53 months ]An AE is any unfavorable and unintended sign, symptom, or disease (new or exacerbated) in a clinical study participant, temporally associated with the use of study treatment, whether or not considered related to the study treatment. The number of participants experiencing an AE will be assessed.
- Number of Participants Discontinuing Study Treatment due to an Adverse Event (AE) [ Time Frame: Up to 52 months ]The number of participants discontinuing study treatment due to an AE will be assessed.
- Time to Earliest Progression by Cancer Antigen-125 (CA-125) [ Time Frame: Up to 53 months ]For participants with BRCA1/2 non-mutated ovarian cancer only, the time to earliest progression by CA-125 will be assessed. Progression by CA-125 is defined as an increase in CA-125 level ≥2x upper limit normal (ULN) on 2 occasions, 1 week apart. For participants with elevated CA-125 (≥ULN) at baseline, progression by CA-125 is defined as an increase in CA-125 level ≥2x the nadir value on 2 occasions, 1 week apart.
