Intervention/exposure

Description of intervention(s) / exposure
Treatment: Drugs - Apalutamide
Treatment: Drugs - Androgen Deprivation Therapy (ADT)
Treatment: Drugs - Placebo

Experimental: Apalutamide + ADT - Participants will receive androgen deprivation therapy (ADT) plus oral administration of apalutamide 240 milligram (mg) (4 tablets of 60 mg each) daily in each cycle (each cycle of 28 days). Participants will receive six cycles of treatment, followed by radical prostatectomy (RP) with pelvic lymph node dissection (pLND), followed by an additional six cycles of treatment.

Experimental: Placebo + ADT - Participants will receive ADT with oral administration of matching placebo treatment daily in each cycle (each cycle of 28 days). Participants will receive six cycles of placebo treatment, followed by RP with pLND, followed by an additional six cycles of placebo treatment.


Treatment: Drugs: Apalutamide
Participants will receive apalutamide 240 mg (4 tablets of 60 mg each) orally once daily.

Treatment: Drugs: Androgen Deprivation Therapy (ADT)
Participants will receive a stable regimen of ADT - gonadotropin-releasing hormone analog (agonist or antagonist) (GnRHa). ADT is a kind of hormone therapy for prostate cancer. GnRHa will be administrated to achieve and maintain sub-castrate concentrations of testosterone (50 nanogram per deciliter \[ng/dL\]).

Treatment: Drugs: Placebo
Participants will receive matching placebo oral tablets daily.

* High-risk disease defined by a total Gleason Sum Score greater than equal to (>=) 4+3 (=Grade Groups [GG] 3 5) and >=1 of the following 4 criteria: a) Any combination of Gleason Score 4+3 (= 3) and Gleason Score 8 (4+4 or 5+3) in >= 6 systematic cores (with >=1 core Gleason Score 8 [4+4 or 5+3] included); b) Any combination of Gleason Score 4+3 (=GG 3) and Gleason Score 8 (4+4 or 5+3) in >=3 systematic cores and Prostate-specific antigen (PSA) >=20 ng/mL (with >= 1 core Gleason Score 8 [4+4 or 5+3] included); c) Gleason Score >=9 (=GG 5) in at least 1 systematic or targeted core; d) At least 2 systematic or targeted cores with continuous Gleason Score >=8 (=GG 4), each with > 80 percent (%) involvement
* Candidate for radical prostatectomy with pelvic lymph node dissection as per the investigator
* Eastern Cooperative Oncology Group (ECOG) Performance Status score of 0 or 1
* Contraceptive use by male participants (and female partners of male participants enrolled in the study who are of childbearing potential or are pregnant) should be consistent with local regulations regarding the use of contraceptive methods for participants participating in clinical studies

Can healthy volunteers participate?
No
Key exclusion criteria
* Distant metastasis based on conventional imaging (clinical stage M1). 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. Participants are considered eligible only if the central radiological review confirms clinical stage M0
* (a) Prior treatment with androgen receptor antagonists; (b) Treatment with gonadotropin-releasing hormone analog (GnRHa) prior to informed consent form (ICF) signature
* History of prior systemic or local therapy for prostate cancer, including pelvic radiation for prostate cancer
* Use of any investigational agent less than or equals to (<=)4 weeks prior to randomization or any therapeutic procedure for prostate cancer at any time
* Major surgery <=4 weeks prior to randomization
* Any of the following within 12 months prior to first dose of study drug: severe or unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events (example, pulmonary embolism, cerebrovascular accident including transient ischemic attacks), or clinically significant ventricular arrhythmias or New York Heart Association Class II to IV heart disease; uncomplicated deep vein thrombosis is not considered exclusionary
