A Multicenter, Randomized, Double-Blind, Placebo-Controlled, Phase IV Study of Apalutamide in Chinese Participants With Non-Metastatic Castration-Resistant Prostate Cancer (NM-CRPC)
In Brief
A Phase 4 clinical trial evaluating Apalutamide, Placebo, and 1 other intervention for Prostatic Neoplasms. Active but no longer recruiting, targeting 75 participants across 27 sites.

Detailed Summary
The purpose of this study is to compare the improvement in time to prostate specific antigen (PSA) progression (TTPP, as defined by Prostate Cancer Working Group 2 \[PCWG2\]) of apalutamide versus placebo in Chinese participants with high-risk non-metastatic castration resistant prostate cancer (NM-CRPC).
Study Details
Timeline
Arms & Interventions
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.
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.
Interventions
Apalutamide 240 mg (4\*60 mg tablets) will be administrated orally once daily.
Matching placebo will be administered orally.
Participants will continue to receive ADT with gonadotrophin-releasing hormone agonists (GnRHa) who have not been surgically castrated.
