Who may be able to join
- Histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features, with high risk for development of metastases, defined as prostate-specific antigen doubling time (PSADT) less than or equals to (<=) 10 months. PSADT is calculated using at least 3 prostate-specific antigen (PSA) values obtained during continuous androgen deprivation therapy (ADT)

If the participant is medically castrated, continuous dosing with gonadotropin releasing hormone analog (GnRHa) must have been initiated at least 4 weeks prior to randomization and must be continued throughout the study to maintain castrate levels of testosterone
- Participants who received a first-generation anti-androgen (example: bicalutamide, flutamide, nilutamide) must have at least a 4-week washout prior to randomization and must show continuing disease progression (an increase in PSA) after washout
- At least 4 weeks must have elapsed from major surgery or radiation therapy prior to randomization
Who cannot join
- Presence of distant metastases, including central nervous system (CNS) and vertebral or meningeal involvement, or history of distant metastases. Exception: Pelvic lymph nodes <2 centimeter in short axis (N1) located below the iliac bifurcation are allowed
- Symptomatic loco-regional disease requiring medical intervention, such as moderate or severe urinary obstruction or hydronephrosis, due to primary tumor (example, tumor obstruction of bladder trigone)
- Prior treatment with cytochrome P450 17 alpha-hydroxylase/17,20-lyase (CYP17) inhibitors (example: abiraterone acetate, orteronel, galerterone, ketoconazole, aminoglutethimide) for PC
- Prior chemotherapy for PC, except if administered in the adjuvant/neoadjuvant setting
- Prior treatment with second generation anti-androgens (example, enzalutamide)
- History of seizure or condition that may pre-dispose to seizure (example: prior stroke within 1 year prior to randomization, brain arteriovenous malformation, schwannoma, meningioma, or other benign CNS or meningeal disease which may require treatment with surgery or radiation therapy)

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ApalutamideDrug
Also called JNJ-56021927, ARN-509
Apalutamide 240 mg (4*60 mg tablets) will be administrated orally once daily.
PlaceboDrug
Matching placebo will be administered orally.
Androgen-deprivation Therapy (ADT)Drug
Participants will continue to receive ADT with gonadotrophin-releasing hormone agonists (GnRHa) who have not been surgically castrated.
| Study group | Role | What they receive |
|---|---|---|
| Apalutamide 240 milligram (mg) plus ADT | Experimental | Participants will receive apalutamide 240 mg orally daily from Day 1 of Cycle 1 until disease progression, unacceptable toxicity, withdrawal of consent, death or termination of the study along with androgen-deprivation therapy (ADT). Each treatment cycle will consist of 28 days. Receives: Drug: Apalutamide; Drug: Androgen-deprivation Therapy (ADT) |
| Placebo plus ADT | Placebo comparator | Participants will receive matching placebo daily along with ADT from Cycle 1 Day 1 until disease progression, unacceptable toxicity, withdrawal of consent, death or termination of the study. Participants who do not have distant metastasis will switch to treatment with apalutamide after completion of 5 cycles of placebo treatment. Participants who have prostate-specific antigen (PSA) progression prior to completion of 5 cycles of study treatment, will cross over to apalutamide at the time of PSA progression. Each treatment cycle will consist of 28 days. Receives: Drug: Placebo; Drug: Androgen-deprivation Therapy (ADT) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time to Prostate Specific Antigen (PSA) Progression (TTPP) Based on Prostate Cancer Working Group 2 (PCWG2) Criteria
Time to prostate specific antigen progression (TTPP) was defined as the time from randomization to the first date of documented PSA progression based on PCWG2 criteria. PCWG2 was defined as the PSA progression as 1) the date that a 25 percent (%) or greater increase and an absolute increase of 2 nanograms per milliliter (ng/mL) or more from the Nadir was documented, which was confirmed by a second value obtained 3 or more weeks later. 2) Where no decline from baseline was documented as a 25% increase from the baseline value along with an increase in absolute value of 2 ng/mL or more after 12 week of treatment. Kaplan-Meier method was used for the analysis.
Measured: From randomization until first documented PSA progression (up to 3 years 3 months)
Secondary outcomes (4)
Number of Participants With Treatment-emergent Adverse Events (TEAEs) and Treatment-emergent Serious Adverse Events (TESAEs)
Measured: Up to 6 years 4 months
Number of Participants With Grade 3 or Higher Abnormalities in Laboratory Values
Measured: Up to 6 years 4 months
Percentage of Participants Who Achieved Prostate Specific Antigen (PSA) Response (>=50% PSA Reduction)
Measured: Up to 6 years 4 months
Plasma Concentration of Apalutamide and Its Metabolite (N-desmethyl Apalutamide)
Measured: Presdose: Day 1 of Cycles 1, 2, 3, and 6; 2 hours postdose: Day 1 of Cycles 1 and 3

A Phase 4 study testing Apalutamide and Androgen-deprivation Therapy (ADT) in people with Prostatic Neoplasms, run by Janssen Research & Development, LLC at 27 sites in China.
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 5 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: finished, as of the sponsor's last update on 30 Jul 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 27 sites in China. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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 28 Mar 2025). 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?
Time to Prostate Specific Antigen (PSA) Progression (TTPP) Based on Prostate Cancer Working Group 2 (PCWG2) Criteria (time frame: From randomization until first documented PSA progression (up to 3 years 3 months)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 30 Jul 2026.
