About this study
Official title: A Phase 3 Randomized, Placebo-controlled Double-blind Study of JNJ-56021927 in Combination With Abiraterone Acetate and Prednisone Versus Abiraterone Acetate and Prednisone in Subjects With Chemotherapy-naive Metastatic Castration-resistant Prostate Cancer (mCRPC)
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]).
Read the 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.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ApalutamideDrug
Participants will receive 240 mg (4*60 mg tablets) of apalutamide once daily orally.
Abiraterone acetateDrug
Also called ZYTIGA
Participants will receive 1000 mg (4*250 mg tablets) of abiraterone acetate (AA) once daily orally.
PrednisoneDrug
Participants will receive 5 mg tablet of prednisone twice daily orally.
PlaceboDrug
Participants will receive matching placebo to apalutamide once daily orally.
| Study group | Role | What they receive |
|---|---|---|
| Group 1: AAP and apalutamide | Experimental | 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). Receives: Drug: Apalutamide; Drug: Abiraterone acetate; Drug: Prednisone |
| Group 2: AAP and Placebo | Placebo comparator | 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). Receives: Drug: Abiraterone acetate; Drug: Prednisone; Drug: Placebo |
What is being measured
The primary outcome is the main question the study is designed to answer.
Radiographic Progression-free Survival (rPFS)
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.
Measured: Up to 3 years and 4 months
Secondary outcomes (4)
Overall Survival (OS)
The OS was defined as the time from randomization to date of death from any cause.
Measured: Up to 5 years and 10 months
Time to Chronic Opioid Use
Time to chronic opioid use was defined as the time from date of randomization to the first date of opioid use.
Measured: Up to 5 years and 10 months
Time to Initiation of Cytotoxic Chemotherapy
Time to initiation of cytotoxic chemotherapy was defined as the time from date of randomization to the date of initiation of cytotoxic chemotherapy.
Measured: Up to 5 years and 10 months
Time to Pain Progression
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.
Measured: Up to 5 years and 10 months

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Apalutamide, Abiraterone acetate and Prednisone in people with Prostatic Neoplasms, run by Aragon Pharmaceuticals, Inc. at 173 sites in 16 countries.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 6 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: under way, not looking for participants, as of the sponsor's last update on 4 Nov 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 173 sites in United States, Japan, United Kingdom, Canada, Australia and 11 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 16 Aug 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Radiographic Progression-free Survival (rPFS) (time frame: Up to 3 years and 4 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02257736, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2026.
