Description of intervention(s) / exposure
Treatment: Drugs - Apalutamide
Treatment: Drugs - Abiraterone acetate
Treatment: Drugs - Prednisone
Treatment: Drugs - Placebo

Experimental: Group 1: AAP and apalutamide - Participants will receive apalutamide 240 milligram (mg) (4\*60 mg tablets) and abiraterone acetate (AA) 1000 mg (4\*250 mg tablets) once daily on an empty stomach and 5 mg prednisone (P), AAP, twice daily, until disease progression, unacceptable toxicity or end of treatment, whichever occurs first. After unblinding participants will be offered further treatment as defined in the Open-Label Extension (OLE) or Long-Term Extension (LTE) phase (AAP + open label apalutamide or AAP alone).

Placebo comparator: Group 2: AAP and Placebo - Participants will receive matching Placebo of apalutamide and abiraterone acetate (AA) 1000 mg (4\*250 mg tablets) once daily on an empty stomach and 5 mg prednisone (P), AAP, twice daily until disease progression, unacceptable toxicity or end of treatment, whichever occurs first. After unblinding participants will be offered further treatment as defined in the OLE or LTE phase (AAP + open label apalutamide or AAP alone).


Treatment: Drugs: Apalutamide
Participants will receive 240 mg (4\*60 mg tablets) of apalutamide once daily orally.

Treatment: Drugs: Abiraterone acetate
Participants will receive 1000 mg (4\*250 mg tablets) of abiraterone acetate (AA) once daily orally.

Treatment: Drugs: Prednisone
Participants will receive 5 mg tablet of prednisone twice daily orally.

Treatment: Drugs: Placebo
Participants will receive matching placebo to apalutamide once daily orally.

Eligibility
Key inclusion criteria
* Adenocarcinoma of the prostate
* Metastatic disease as documented by technetium-99m (99mTc) bone scan or metastatic lesions by computed tomography (CT) or magnetic resonance imaging (MRI) scans (visceral or lymph node disease). If lymph node metastasis is the only evidence of metastasis, it must be greater than or equal to (>=) 2 centimeter (cm) in the longest diameter
* Castration-resistant prostate cancer demonstrated during continuous androgen deprivation therapy (ADT), defined as 3 rises of PSA, at least 1 week apart with the last androgen deprivation therapy (PSA) >= 2 nanogram per milliliters (ng/mL)
* Participants who received a first generation anti-androgen (eg, bicalutamide, flutamide, nilutamide) must have at least a 6-week washout prior to randomization and must show continuing disease (PSA) progression (an increase in PSA) after the washout period
* Prostate cancer progression documented by prostate-specific antigen (PSA) according to the Prostate Cancer Clinical Trials Working Group (PCWG2) or radiographic progression of soft tissue according to modified Response Evaluation Criteria in Solid Tumors, version 1.1 (RECIST) modified based on PCWG2, or radiographic progression of bone according to PCWG2
* Participants who cross-over from Prednisone alone to open-label apalutamide plus AAP should still be in the double-blind phase of the study, should be receiving AAP alone and should have ECOG 0-1-2.

Key exclusion criteria
* Small cell or neuroendocrine carcinoma of the prostate

* Therapies that must be discontinued or substituted at least 4 weeks prior to randomization include the following: a) Medications known to lower the seizure threshold, b) Herbal and non-herbal products that may decrease PSA levels (example [eg], saw palmetto, pomegranate) or c) Any investigational agent
* At Screening need for parenteral or oral opioid analgesics (eg, codeine, dextropropoxyphene)
