1.Primary Outcome
Title Progression-Free Survival (PFS) in Cohort With Germline BRCA Mutation (gBRCA)
Hide Description PFS was defined as the time between randomization and disease progression or death from any cause. Computed tomography or magnetic resonance imaging to assess disease progression was performed at baseline, every 8 weeks through cycle 14, and then every 12 weeks until treatment discontinuation. The objective assessment of disease progression was determined by means of central radiologic and clinical review, according to Response Evaluation Criteria in Solid Tumors (RECIST),version 1.1, which was performed in a blinded fashion.
Time Frame From date of randomization to the earliest date of disease progression or death from any cause.

Title Progression-Free Survival 2 (PFS2) in Cohort With Germline BRCA Mutation (gBRCA)
Hide Description Patients were to be followed off treatment every 3 months for subsequent anti-cancer treatment, including outcome of such therapy, any new malignancies, and survival status. PFS2 was defined as the time from treatment randomization to the earlier of the date of disease progression on the next anti-cancer therapy following study treatment or death due to any cause. This study is ongoing, PFS2 is immature at this stage of primary analysis.

Title Progression-Free Survival 2 (PFS2) in Cohort With No Germline BRCA Mutation (Non-gBRCA)
Hide Description Patients were to be followed off treatment every 3 months for subsequent anti-cancer treatment, including outcome of such therapy, any new malignancies, and survival status. PFS2 was defined as the time from treatment randomization to the earlier of the date of disease progression on the next anti-cancer therapy following study treatment or death due to any cause. This study is ongoing, PFS2 is immature at this stage of primary analysis.
Time Frame From treatment randomization to the earlier of the date of disease progression on the next anti-cancer therapy following study treatment or death due to any cause.

Title Change From Baseline in EQ-5D-5L in Cohort With Germline BRCA
Hide Description EQ-5D-5L is a well-validated, general preference-based, health-related QoL instrument. The EQ-5D-5L encompasses 5 domains, asking patients to rate their perceived health state today on the following dimensions: Mobility, Self-Care, Usual Activities, Pain/Discomfort, and Anxiety/Depression. Each domain has 5 possible levels: "no problems" (Level 1), "slight problems" (Level 2), "moderate problems" (Level 3), "severe problems" (Level 4), and "extreme problems" (Level 5). Each domain is assigned a level, and levels are combined to create a 5-digit number describing the patient's health state. For each patient, an index value is determined from a published country-specific value set. This index value or utility score ranges from 0 to 1.00 (with 1.0 representing perfect health) and is used in the calculation of quality-adjusted life years (QALYs) that are used to inform economic valuations of health interventions. A positive change from baseline indicates improvement.
