Summary

The purpose of this study is to determine if apalutamide plus gonadotropin releasing hormone (GnRH) agonist in participants with high-risk, localized or locally advanced prostate cancer receiving primary radiation therapy results in an improvement of metastasis-free survival. The study will include a Screening Phase, Treatment Phase, a Posttreatment Phase, and a Long-term Follow-up Phase.

Inclusion Criteria

Indicated and planned to receive primary radiation therapy for prostate cancer
Histologically confirmed cancer of an intact prostate, and 1 of the following at diagnosis: 1) Gleason score >=8 and >=cT2c, 2) Gleason score >=7, PSA >=20 nanogram per milliliters (ng/mL), and >=cT2c
Charlson index (CCI) <=3
An Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) grade of 0 or 1
Adequate organ function: (1) aspartate aminotransferase (AST), alanine aminotransferase (ALT), within normal limits (WNL), (2) serum creatinine less than (<) 1.5 milligram/deciliter (mg/dL) (<133 micromoles/Liter [mcmol/L]), (3) platelets greater than or equal to (>=)140,000/microLiter (mcL), independent of transfusion and/or growth factors within 3 months prior to randomization, (4) Hemoglobin >= 12.0 gram/deciliter (g/dL) (7.4 millimloes [mmol], independent of transfusion and/or growth factors within 3 months prior to randomization
Participants who are sexually active (even men with vasectomies) and willing to use a condom and agree not to donate sperm during the trial

Exclusion Criteria

Presence of distant metastasis, (clinical stage M1). Isolated pelvic nodal disease below the iliac bifurcation (clinical stage N1) is not an exclusion. Diagnosis of distant metastasis (clinical M stage; M0 versus M1a, M1b, M1c) and pelvic nodal disease (clinical N stage; N1 versus N0) will be assessed by central radiological review. Patients are considered eligible only if the central radiological review confirms clinical stage M0
Prior treatment with gonadotropin releasing hormone (GnRH) analogue or anti-androgen or both for >3 months prior to randomization
Bilateral orchiectomy
History of pelvic radiation
Prior systemic (example [e.g.], chemotherapy) or local (e.g. radical prostatectomy, cryotherapy) treatment for prostate cancer
History of seizure or any condition that may predispose to seizure (including, but not limited to prior stroke, transient ischemic attack or loss of consciousness <= 1 year prior to randomization; brain arteriovenous malformation; or intracranial masses such as schwannomas and meningiomas that are causing edema or mass effect)
Prior treatment with enzalutamide, abiraterone acetate, orteronel, galeterone, ketoconazole, aminoglutethimide, estrogens, megestrol acetate, and progestational agents (including cyproterone acetate) for prostate cancer
Prior treatment with radiopharmaceutical agents (e.g., strontium-89) or immunotherapy (e.g., sipuleucel-T) for prostate cancer
Prior treatment with systemic glucocorticoids ≤4 weeks prior to randomization or is expected to require long-term use of corticosteroids during the study
Use of 5-alpha reductase inhibitors (e.g., dutasteride, finasteride) <=4 weeks prior to randomization
Use of any investigational agent <=4 weeks prior to randomization
Current chronic use of opioid analgesics for >=3 weeks for oral or >7 days for non-oral formulations
Major surgery <=4 weeks prior to randomization
Current or prior treatment with anti-epileptic medications for the treatment of seizures
Gastrointestinal conditions affecting absorption
Known or suspected contraindications or hypersensitivity to apalutamide, bicalutamide or GnRH agonists or any of the components of the formulations
