Brief Summary:
The purpose of this study is to compare the radiographic progression-free survival (rPFS) of apalutamide in combination with abiraterone acetate (AA) plus prednisone or prednisolone (AAP) and AAP in participants with chemotherapy-naive (participants who did not receive any chemotherapy [treatment of cancer using drugs]) metastatic castration-resistant prostate cancer (mCRPC) (cancer of prostate gland [gland that makes fluid that aids movement of sperm]).

Condition or disease Intervention/treatment Phase
Prostatic Neoplasms Drug: Apalutamide Drug: Abiraterone acetate Drug: Prednisone Drug: Placebo Phase 3

Detailed Description:
This is a randomized (study drug assigned by chance), double-blind (neither the Investigator nor the participant know the treatment) placebo-controlled and multicenter (when more than 1 hospital or medical school team work on a medical research study) study to determine if participants with chemotherapy-naive mCRPC will benefit from the addition of apalutamide to AAP compared with AAP alone. The study consists of 3 phases: Screening phase; Treatment phase, and Follow-up phase. At the final analysis, the study will be unblinded. After the Independent Data Monitoring Committee (IDMC) review and the sponsor's subsequent decision participants will be offered to receive treatment either in the Open-Label Extension Phase or the Long-Term Extension Phase of study. Participants' safety will be monitored throughout the study.

Arm Intervention/treatment
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.

Other Name: ZYTIGA

Drug: Prednisone
Participants will receive 5 mg tablet of prednisone twice daily orally.
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).
 Drug: Abiraterone acetate
Participants will receive 1000 mg (4*250 mg tablets) of abiraterone acetate (AA) once daily orally.
Other Name: ZYTIGA

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

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


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Radiographic Progression-free Survival (rPFS) [ Time Frame: Up to 3 years and 4 months ]
    The rPFS was defined as the time from randomization to the occurrence of one of the following: 1) a participant was considered to have progressed by bone scan if - a) the first bone scan with greater than or equal to (>=) 2 new lesions compared to baseline was observed in less than (<) 12 weeks from randomization and was confirmed by a second bone scan taken >=6 weeks later showing >=2 additional new lesions (a total of >=4 new lesions compared to baseline), b) the first bone scan with >=2 new lesions compared to baseline was observed in >=12 weeks from randomization and the new lesions were verified on the next bone scan >=6 weeks later (a total of >=2 new lesions compared to baseline); 2) progression of soft tissue lesions measured by computerized tomography (CT) or magnetic resonance imaging (MRI) as per Response Evaluation Criteria in Solid Tumors (RECIST) Version 1.1.


Secondary Outcome Measures :
  1. Overall Survival (OS) [ Time Frame: Up to 5 years and 10 months ]
    The OS was defined as the time from randomization to date of death from any cause.

  2. Time to Chronic Opioid Use [ Time Frame: Up to 5 years and 10 months ]
    Time to chronic opioid use was defined as the time from date of randomization to the first date of opioid use.

  3. Time to Initiation of Cytotoxic Chemotherapy [ Time Frame: Up to 5 years and 10 months ]
    Time to initiation of cytotoxic chemotherapy was defined as the time from date of randomization to the date of initiation of cytotoxic chemotherapy.

  4. Time to Pain Progression [ Time Frame: Up to 5 years and 10 months ]
    Time to pain progression: time from randomization to first date that participant either experienced an increase by 2 points from baseline in Brief Pain Inventory Short Form (BPI-SF) worst pain intensity item (item 3) or Case Report Form (CRF) pain, observed at 2 consecutive evaluations >=4 wks apart, or initiation of chronic opioids as defined in time to chronic opioid use, whichever occurred first. BPI-SF is a self-administered questionnaire developed to assess severity of pain and impact of pain on daily functions. Item 3(worst pain intensity) asks participants to rate worst pain in prior 7-days on a 0-10 numeric rating scale, where "0" indicates "No pain" and "10" indicates "Pain as bad as you can imagine." A lower score is better.CRF pain refers to participant's response to global pain assessment "How would you rate your pain over the past 7 days?"with a scale of 0("No pain") to 10("Pain as bad as you can imagine"),that is systematically reported and recorded on the eCRF.
