  Purpose
The purpose of this study is to evaluate if the anti-tumor activity of JNJ-809 combined with apalutamide is improved compared with apalutamide alone for subjects with metastatic castration-resistant prostate cancer (mCRPC).

Primary Outcome Measures:
  • Time to Prostate-specific Antigen (PSA) Progression [ Time Frame: approximately 2 years ]
    Time to PSA progression will be measured using Prostate Cancer Working Group 3 (PCWG3).


Secondary Outcome Measures:
  • PSA Doubling Time (PSADT) [ Time Frame: approximately 2 years ]
    The PSADT will be determined using the method as recommended by PCWG3 criteria.

  • Radiographic Progression-free Survival [ Time Frame: approximately 2 years ]
    Radiographic progression-free survival, is defined as the time from the date of randomization to the date of radiographic progression or death, whichever occurs first.

  • Time to Unequivocal Clinical Progression [ Time Frame: approximately 2 years ]
    Time to unequivocal clinical progression defined as the time from the date of randomization to the date of unequivocal clinical progression as evaluated by the investigator.

  • Overall Survival [ Time Frame: approximately 2 years ]
    Overall survival defined as time from the date of randomization to death from any cause.

  • Number of Participants With Adverse Events (AEs) as a Measure of Safety and Tolerability [ Time Frame: approximately 2 years ]
    Comparison of the AE profiles of the two treatment groups.

  • Blood Culture and Shedding Profile of JNJ-809 From Cultured Samples of Feces, Urine, and Saliva [ Time Frame: approximately 2 years ]
    Blood culture samples will be collected after the mandatory prophylactic antibiotic therapy. Bacterial shedding will be evaluated from cultured samples of feces by stool or rectal swab, urine, and sputum.
