  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Eastern Cooperative Oncology Group (ECOG) performance status less than or equal to (<=) 2
  • Histologically or cytologically confirmed adenocarcinoma of the prostate without neuroendocrine differentiation or small cell features
  • Metastatic disease as documented by bone scan or metastatic lesions by computed tomography or magnetic resonance imaging scans (visceral or lymph node disease).

  • Prior hormonal interventions (including 1st generation antiandrogens [flutamide, bicalutamide, nilutamide], steroids, estrogens, finasteride, dutasteride) for PC are allowed. These therapies, except for gonadotropin releasing hormone analogs (GnRH) analogs and prednisone/prednisolone, must have been discontinued for minimally 4 weeks (2 weeks only for flutamide, nilutamide, or finasteride) before first dose of study drug

Who cannot join

  • Known brain metastases
  • Chemotherapy, or immunotherapy within 2 weeks or 5 half-lives of the drug prior to the first dose of study drug, whichever is longer, with a maximum of 4 weeks.
  • Prior treatment with second-generation anti-androgens (example [eg], enzalutamide)
  • Administration of an investigational therapeutic within 2 weeks or 5 half-lives of the drug prior to the first dose of study drug, whichever is longer, with a maximum of 4 weeks. And participant use radiopharmaceutical agents (eg, strontium-89) or investigational immunotherapy (eg, sipuleucel-T) within 12 weeks prior to the first dose of study drug
  • Prior treatment with cytochrome 17 inhibitors (eg, abiraterone acetate, orteronel, galeterone, systemic ketoconazole)

Official title: A Phase 1 Study of Androgen Receptor (AR) Antagonist Apalutamide in Chinese Subjects With Metastatic Castration-Resistant Prostate Cancer

The purpose of this study is to evaluate pharmacokinetics (PK) following a single dose and multiple dose treatment and the safety of apalutamide in Chinese participants with metastatic castration resistant prostate cancer (mCRPC) at dose of 240 milligram (mg).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ApalutamideDrug

    Also called JNJ-56021927

    The participants will receive apalutamide 240 mg once daily orally.

Study groups in NCT03523442
Study groupRoleWhat they receive
ApalutamideExperimentalParticipants will receive a single oral dose of apalutamide 240 milligram (mg) during pharmacokinetics (PK) Week Day 1 and will be monitored for one week (that is; PK Week) to assess PK and safety of drug. Subsequently, participants will further receive daily treatment of apalutamide from Cycle 1 Day 1 onwards until disease progression, withdrawal of consent, lost to follow-up, or the occurrence of unacceptable toxicity. Each treatment cycle consists of 28 days. After final analysis (FA), participants who are receiving apalutamide in the open-label treatment phase may continue receiving single oral dose apalutamide 240 mg once daily in a long-term extension (LTE) phase if they continue to derive benefit from treatment (based on investigator assessment).
Receives: Drug: Apalutamide

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Plasma Concentration of Apalutamide

    Plasma concentration of apalutamide will be reported.

    Measured: Predose; postdose up to 168 hours (hrs) (Cycle1 Day 7), Cycle 2 (pre-dose; on Day 1 and 15 of cycle 2) and Cycle 3 (pre-dose; up to 24 hrs post-dose). Each cycle is of 28 days

  2. Number of Participants with Adverse Events

    An adverse event is any untoward medical event that occurs in a participant administered an investigational product, and it does not necessarily indicate only events with clear causal relationship with the relevant investigational product.

    Measured: Up to 30 days of last study treatment (approximately 18 months)

Secondary outcomes (2)
  1. Change from Baseline in Serum Prostate Specific Antigen (PSA) at Weeks 4 and 12

    Change from baseline in serum PSA levels will be determined.

    Measured: Baseline, at Weeks 4 and 12 or earlier for those who discontinue therapy (up to approximately 4 months).

  2. Maximal Decline in Prostate Specific Antigen

    Maximal decline in PSA levels will be determined.

    Measured: Up to 30 days of last study treatment (approximately 18 months)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Apalutamide in people with Prostatic Neoplasms, run by Janssen Research & Development, LLC at 4 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 5 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 3 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 4 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. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

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?

Plasma Concentration of Apalutamide (time frame: Predose; postdose up to 168 hours (hrs) (Cycle1 Day 7), Cycle 2 (pre-dose; on Day 1 and 15 of cycle 2) and Cycle 3 (pre-dose; up to 24 hrs post-dose). Each cycle is of 28 days). The study lists 2 primary outcomes in all. 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 3 Nov 2026.
