- Time to Biochemical Recurrence (BCR) [ Time Frame: Month 24 ]BCR is defined as a confirmed prostate specific antigen (PSA) greater than (>) 0.2 nanogram per milliliter (ng/ml) and time to BCR will be analyzed using Kaplan-Meier method.
- Time to BCR [ Time Frame: Month 12 ]BCR is defined as a confirmed PSA > 0.2 ng/ml and time to BCR will be analyzed using Kaplan-Meier method.
- Time to Serum Testosterone Recovery [ Time Frame: Months 18 and 24 ]The testosterone recovery, defined as a serum testosterone greater than or equal to (>=)150 nanograms per deciliter (ng/dL) which will be analyzed using Kaplan-Meier method.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | Male |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- A candidate for radical prostatectomy (RP) or status post (less than or equal to (<=) 60 days) RP. Post RP prostate-specific antigen (PSA) of <= 0.2 nanograms per milliliter (ng/mL) and who has not received other treatment for prostate cancer
- Have recovered from RP procedure, per the clinical judgement of the investigator
- Adequate organ function (hepatic, renal, hematologic and cerebral) determined at the discretion of the treating physician
- Eastern Cooperative oncology Group (ECOG) Performance Status Score of 0 or 1
- Histologically confirmed adenocarcinoma of the prostate and categorized as high risk for recurrent prostate cancer. High risk is defined as: PSA greater than or equal to (>=) 20 ng/ml or; Gleason Score >= 9 in any core or; Gleason Score >= 8 (4+4 or 5+3) in greater than (>) 80 percentage (%) of 2 continuous cores or; Gleason Score = 8 (4+4 or 5+3) in 1 core as long 5 or more other cores with minimum Gleason Score of 4+3
Exclusion Criteria:
- History or presence of soft tissue/bone metastasis or metastasis in distant lymph nodes (pelvic lymph nodes below the iliac bifurcation that are less than (<) 2 centimeter (cm) in diameter [short axis] either radiographically or pathologically are allowed.)
- History of bilateral orchiectomy
- Received an investigational intervention <= 4 weeks before the planned first dose of study intervention
- History of seizure or any condition that in the opinion of the investigator may predispose to seizure or treatment with drugs known to lower the seizure threshold within 4 weeks prior to starting treatment with apalutamide
- Allergy or hypersensitivity to apalutamide, or excipients, unable or unwilling to take androgen deprivation therapy (ADT)
