Brief Summary:
The purpose of this study is to establish the recommended phase 2 dose (RP2D) of niraparib combination therapies of Part 1 and to evaluate the antitumor activity and safety of niraparib combination therapies of Part 2.

Condition or disease Intervention/treatment Phase
Prostatic Neoplasms, Castration-Resistant Drug: Niraparib 200 mg Drug: JNJ-63723283 240 mg Drug: JNJ-63723283 480 mg Drug: Abiraterone Acetate Drug: Prednisone Phase 1 Phase 2

Detailed Description:
This multicenter study will evaluate safety and efficacy of niraparib in combination with other anti-cancer agents. Two combinations are being studied: the first combination study will combine niraparib with the anti-programmed cell death protein (PD)-1 monoclonal antibody, JNJ-63723283 in participants with metastatic castration-resistant prostate cancer (mCRPC). The second combination will combine niraparib with abiraterone acetate plus prednisone (AA-P) in mCRPC participants with DNA-repair gene defects (DRD). Combination 1 has 2 parts: in Part 1 (dose selection), participants will be enrolled to explore 2 doses of niraparib and JNJ-63723283; and Part 2 (dose expansion) will evaluate the combination therapy in an expanded number of participants. In Part 2, participants will be enrolled into 2 cohorts based on biomarker status. Combination 2 has only 1 part (Part 2) and no Part 1. In Part 2, participants will be enrolled into 4 cohorts (breast cancer gene [BRCA] biallelic loss [2A], other DRD biallelic loss [2B], BRCA monoallelic loss [2C], and other DRD monoallelic loss [2D]). Each combination in the study will have 4 phases: A Prescreening Phase, a Screening Phase, a Treatment Phase, and a Follow-up Phase. Study evaluations will include efficacy, pharmacokinetic (PK), PK/pharmacodynamics, biomarkers, safety and tolerability.

Primary Outcome Measures :
  1. Part 1: Combination 1: Incidence of Specified Toxicities [ Time Frame: Up to 28 days ]
    Incidence defined as number of participants with specified toxicities will be reported. The dose will be considered intolerable if a participant developed Grade greater than or equal to (>=) 3 non-hematological toxicity (with exceptions including anorexia, fever, constipation, fatigue that improves to Grade less than or equal to (<=) 2 in <=7 days, vomiting and diarrhea that resolves in <=3 days with best supportive care), treatment-related Grade 4 thrombocytopenia or Grade >= 3 thrombocytopenia, treatment-related Grade 4 neutropenia >= 7 days, or Grade 3 or 4 neutropenia, treatment-related serious adverse events.

  2. Part 2: Combination 1: Objective Response Rate (ORR) [ Time Frame: Approximately 24 months ]
    Objective response rate is defined as the percentage of participants who achieve complete response (CR) or partial response (PR), as assessed by response evaluation criteria in solid tumors (RECIST) 1.1 criteria with no evidence of bone progression according to prostate cancer working group 3 (PCWG3) criteria. CR defined as disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to less than 10 millimeter (mm). PR defined as at least 30 percent (%) decrease in sum of the diameters of the target lesions taking as reference the baseline sum diameters.

  3. Part 2: Combination 2: Composite Response Rate (RR) [ Time Frame: Approximately 24 months ]
    Composite response rate (RR) is defined as percentage of participants who have 1 of the following by PCWG3 criteria: Objective response (confirmed per RECIST 1.1), or circulating tumor cells (CTC) response: defined as CTC=0 per 7.5 milliliter (mL) of blood at 8 weeks for participants who have CTC greater than or equal to (>=)1 at baseline or CTC less than (<)5 per 7.5 mL with CTC >=5 at baseline, confirmed by a second consecutive value obtained 4 or more weeks later, or prostate-specific antigen (PSA) decline of >=50%, measured twice 3 to 4 weeks apart.

  4. Part 2: Combinations 1 and 2: Incidence of Adverse Events (AEs) [ Time Frame: Approximately 24 months ]
    Incidence defined as number of participants with AEs will be reported. An AE is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

  5. Part 2: Combinations 1 and 2: Severity of Adverse Events [ Time Frame: Approximately 24 months ]
    An AE is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product. Severity of AEs will be assessed using National Cancer Institute Common Terminology Criteria for Adverse Events (NCI-CTCAE). Any AE not listed in the NCI-CTCAE will be graded according to the investigator's clinical judgment using the standard grades as follows: Grade 1 (Mild): Awareness of symptoms that are easily tolerated, causing minimal discomfort and not interfering with everyday activities; Grade 2 (Moderate): Sufficient discomfort is present to cause interference with normal activity; Grade 3 (Severe): Extreme distress, causing significant impairment of functioning or incapacitation. Prevents normal everyday activities; Grade 4, Life-threatening: Urgent intervention indicated; Grade 5, Death: Death.


Secondary Outcome Measures :

    Duration of objective response is defined as time from complete response (CR) or partial response (PR) to radiographic progression of disease (PD), unequivocal clinical progression, or death, whichever occurs first. CR defined as disappearance of all target lesions. Any pathological lymph nodes must have reduction in short axis to less than 10 millimeter (mm).
