Brief Summary:
The purpose of this study is to investigate potential drug-drug interaction (DDI) between JNJ-56021927 and abiraterone acetate and between JNJ-56021927 and prednisone, determine safety of the combination and evaluate in a descriptive manner the efficacy in these participants. It will also, potentially provide dosing recommendations for abiraterone acetate in future studies when combined with JNJ-56021927.

Detailed Description:
This is a multicenter, open-label (participants will know the identity of study drug received) study in participants with Metastatic Castration-Resistant Prostate Cancer (mCRPC). The study is a single sequence design (ie, all participants will take abiraterone acetate + prednisone [AAP] once daily on Days 1-7 of Treatment Cycle 1 and then proceed with combined daily intake of AAP+JNJ-56021927 from Treatment Cycle 1, Day 8 through to the end of treatment [ie, for up to an expected duration of approximately 18 months] and will be conducted as two cohorts (group of participant's). The study will consist of a 28-day screening phase to determine eligibility, an open-label treatment phase consisting of 28-day treatment cycles, and a 30-day follow-up phase for collection of adverse events (AE) after last dose of study drug. Participants will have blood samples collected during the study to evaluate pharmacokinetics, safety, and antitumor activity (PSA). Participant safety will also be monitored by the collection of adverse events. Imaging assessments for disease evaluation will be planned at discretion of the Investigator. Once all participants have completed study treatment up to Cycle 3 Day 1, a data cutoff is planned to evaluate the short term safety profile of the combination and to complete the PK analysis up to the cutoff date. All participants will continue on study (ie, to receive treatment) until disease progression, withdrawal of consent, lost to follow-up, or the occurrence of unacceptable toxicity. The end of the study is defined when all participants have completed treatment. Participant's safety will be monitored throughout the study.

Arm Intervention/treatment
Experimental: Cohort 1
Participants will receive abiraterone acetate (AA) along with prednisone on Day 1, Treatment Cycle 1 up to Day 7, Treatment Cycle 1; followed by combined intake of abiraterone acetate + prednisone (AAP) + JNJ-56021927 from Day 8, Treatment Cycle 1 up to the end of treatment (EoT) visit (ie, up to approximately 18 months). On Day 8, Treatment Cycle 2 participants will receive JNJ-56021927, 1 hour after intake of AA and prednisone. Breakfast will be offered approximately 30 minutes after intake of JNJ-56021927. Treatment cycles will be of 28 days.
Drug: Abiraterone Acetate
Administered orally (by mouth) once daily in morning at a dose of 1000 mg for up to the end of treatment (EoT) visit (ie, for up to approximately 18 months).
Other Name: ZYTIGA

Drug: Prednisone
Administered orally twice a day at a dose of 5mg for up to the end of treatment (EoT) visit (ie, for up to approximately 18 months).

Drug: JNJ-56021927
Administered orally once daily in morning at a dose of 240 mg starting on Day 8, Treatment Cycle 1 for up to the end of treatment (EoT) visit (ie, for up to approximately 18 months).

Experimental: Cohort 2
Participants will receive abiraterone acetate (AA) along with prednisone on Day 1, Treatment Cycle 1 up to Day 7, Treatment Cycle 1; followed by combined intake of AAP + JNJ-56021927 from Day 8, Treatment Cycle 1 up to the end of treatment (EoT) visit (ie, up to approximately 18 months). On Days 7 and 36, participants will receive AA and prednisone together. On Day 8, Treatment Cycle 2 participants will receive JNJ-56021927, 1 hour after intake of AAP. Treatment cycles will be of 28 days.

Other Name: ZYTIGA

Drug: Prednisone
Administered orally twice a day at a dose of 5mg for up to the end of treatment (EoT) visit (ie, for up to approximately 18 months).

Drug: JNJ-56021927

Primary Outcome Measures :
  1. Area Under the Plasma Concentration-time Curve From Time Zero to Time 24 Hours (AUC [0-24]) of abiraterone [ Time Frame: Day 7 (Treatment Cycle 1) and on Day 36 (Treatment Cycle 2) ]
    The AUC (0-24) is area under the plasma concentration-time curve from time zero to time 24 hours.

  2. Maximum plasma concentration (Cmax) of abiraterone, prednisone and its metabolite prednisolone [ Time Frame: Day 7 (Treatment Cycle 1) and on Day 36 (Treatment Cycle 2) ]
    The Cmax is the maximum observed plasma concentration.

  3. Area Under the Plasma Concentration-time Curve From Time Zero to Time 12 Hours (AUC [0-12]) of prednisone and its metabolite prednisolone [ Time Frame: Day 7 (Treatment Cycle 1) and on Day 36 (Treatment Cycle 2) ]
    The AUC (0-12) is area under the plasma concentration-time curve from time zero to time 12 hours.


Secondary Outcome Measures :
  1. Area Under the Plasma Concentration Curve (AUC [0- 24h]) of JNJ-56021927 and its metabolite JNJ-56142060 [ Time Frame: Day 36 (Treatment Cycle 2), on Day 57 (Treatment Cycle 3) ]
    The AUC (0-24) is area under the plasma concentration-time curve from time zero to time 24 hours.

  2. Maximum plasma concentration (Cmax) of JNJ-56021927 and its metabolite JNJ-56142060 [ Time Frame: Day 36 (Treatment Cycle 2), on Day 57 (Treatment Cycle 3) ]
    The Cmax is the maximum observed plasma concentration.

  3. Change in prostate specific antigen (PSA) [ Time Frame: Up to the end of the treatment phase (approximately 18 months) ]
    Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland.

  4. Maximal decline in prostate specific antigen (PSA) [ Time Frame: Up to the end of the treatment phase (approximately 18 months) ]
    Prostate-specific antigen (PSA) is a protein produced by cells of the prostate gland.
