Experimental: Treatment Sequence ABD
Participants will receive single doses of niraparib and abiraterone acetate (AA) using niraparib Formulation 1 as Treatment A in Treatment Period 1, followed by multiple doses of niraparib and AA using niraparib Formulation 2 as Treatment B in Treatment Period 2, followed by multiple doses of niraparib and AA using niraparib Formulation 4 as Treatment D in Treatment Period 3. From Period 2 onwards and during Extension Phase, all participants will continue to receive treatment with niraparib and AA-prednisone (AAP) or AAP alone.

- Maximum Observed Analyte Concentration at Steady State (Cmax,ss) of Niraparib and Abiraterone Acetate (AA) [Period 2 and Period 3] [ Time Frame: Predose, up to 10 hour post dose ]Cmax,ss is defined as maximum observed analyte concentration at steady state.
- Area Under the Plasma Concentration-time Curve from Time Zero to 24 Hours at Steady State (AUC [0-24h],ss) of Niraparib and AA (Period 2 and Period 3) [ Time Frame: Predose, up to 24 hours post dose ]AUC (0-24h),ss is defined as area under the plasma concentration-time curve from time zero to 24 hours at steady state.
- Ratio of Individual Cmax,ss Values Between Test and Reference Treatment (Period 2 and Period 3) [ Time Frame: Predose, up to 10 hours post dose ]Ratio of individual Cmax,ss values between test and reference treatment will be assessed.
- Ratio of individual AUC (0-24h),ss Values Between Test and Reference Treatment (Period 2 and Period 3) [ Time Frame: Predose, up to 24 hours post dose ]Ratio of individual AUC (0-24h),ss values between test and reference treatment will be assessed.
- Maximum Observed Analyte Concentration at (Cmax) of Niraparib and AA (Period 1) [ Time Frame: Predose, up to 72 hours post dose ]Cmax is defined as maximum observed analyte concentration.
- Area Under the Plasma Concentration-time Curve from Time Zero to 72 Hours (AUC [0-72h]) of Niraparib and AA (Period 1) [ Time Frame: Predose, up to 72 hours post dose ]AUC (0-72h) is defined as area under the plasma concentration-time curve from time zero to 72 hours post dosing.
- Ratio of individual AUC (0-72h) Values Between Test and Reference Treatment (Period 1) [ Time Frame: Predose, up to 72 hours post dose ]Ratio of individual AUC (0-72h) values between test and reference treatment will be assessed.
- Serum Testosterone Level [ Time Frame: Predose on Day -7, Day 11, Day 12 and Day 23 ]Serum testosterone level will be assessed.
- Number of Participants with Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: From study start until study completion (up to 1.4 years) ]An AE is any untoward medical occurrence in a participant participating in a clinical study that does not necessarily have a causal relationship with the pharmaceutical/biological agent under study.
- Number of Participants with AEs by Severity [ Time Frame: From study start until study completion (up to 1.4 years) ]Severity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE) version 5.0. Severity scale ranges from Grade 1 (Mild) to Grade 5 (Death). Grade 1= Mild, Grade 2= Moderate, Grade 3= Severe, Grade 4= Life-threatening and Grade 5= Death.
- Number of Participants with Clinical Laboratory Abnormalities [ Time Frame: From study start until study completion (up to 1.4 years) ]Number of participants with clinical laboratory abnormalities including hematology, serum chemistry and urinalysis will be reported.
