Eligibility Criteria

Inclusion

  • Confirmed diagnosis of prostate adenocarcinoma
  • Age ≥ 18
  • Classified as having National Comprehensive Cancer Network unfavorable intermediate risk prostate cancer (i.e., \[a\] 2 of the following: PSA 10-20 ng/mL, clinical T category 2b-2c, or International Society of Urological Pathology \[ISUP\] grade group 2; \[b\] OR any 1 of \[a\] with ISUP grade group 3 disease; OR \[c\] any 1 of \[a\] with 50% or more cores on systematic biopsy showing prostate cancer)
  • Have a Decipher genomic classifier score
  • Have at least one dominant intraprostatic lesion visible on multiparametric MRI (Prostate Imaging-Reporting and Data System \[PI-RADS\] version 2.1 score 4 or 5)
  • Have underwent a prostate specific membrane antigen (PSMA) positron emission tomography/computed tomography (PET/CT)
  • Have total testosterone \>= 150 ng/dL
  • Adequate performance status (Eastern Cooperative Oncology Group \[ECOG\] 0-1)
  • Hemoglobin ≥ 9.0 g/dL, independent of transfusion and/or growth factors within 3 months prior to randomization (at screening)
  • Platelet count ≥ 100,000 x 10\^9/uL independent of transfusion and/or growth factors within 3 months prior to randomization (at screening)
  • Serum albumin ≥ 3.0 g/dL (at screening)
  • Glomerular filtration rate (GFR) ≥ 45 mL/min (at screening)
  • Serum potassium ≥ 3.5 mmol/L (at screening)
  • Serum total bilirubin ≤ 1.5 x upper limit of normal (ULN) (Note: In subjects with Gilbert's syndrome, if total bilirubin is \> 1.5 x ULN, measure direct and indirect bilirubin and if direct bilirubin is ≤ 1.5 x ULN, subject may be eligible) (at screening)
  • Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) \< 2.5 x ULN (at screening)
  • Medications known to lower the seizure threshold (see list under prohibited medications) must be discontinued or substituted at least 4 weeks prior to study entry

Exclusion

  • Any evidence of spinal cord compression (radiological or clinical)
  • Prior pelvic malignancy
  • Prior pelvic radiation
  • Concurrent malignancy other than adequately treated basal cell or squamous cell skin cancer, non-muscle invasive bladder cancer (NMIBC), or any other cancer in situ currently without evidence of recurrence or progression
  • Inability to undergo radiotherapy, or hormonal therapy
  • Primary small cell carcinoma of the prostate (prostate adenocarcinoma with neuroendocrine differentiation is allowed)
  • Inflammatory bowel disease or active collagen vascular disease
  • History of any of the following:
  • Seizure or known condition that may pre-dispose to seizure (e.g. prior stroke within 1 year to randomization, brain arteriovenous malformation, Schwannoma, meningioma, or other benign central nervous system \[CNS\] or meningeal disease which may require treatment with surgery or radiation therapy)
  • Severe or unstable angina, myocardial infarction, symptomatic congestive heart failure, arterial or venous thromboembolic events (eg, pulmonary embolism, cerebrovascular accident including transient ischemic attacks), or clinically significant ventricular arrhythmias within 6 months prior to randomization
  • Current evidence of any of the following:
  • Uncontrolled hypertension
  • Gastrointestinal disorder affecting absorption
  • Known active infection (eg, human immunodeficiency virus \[HIV\] or viral hepatitis)
  • Any condition that in the opinion of the investigator would preclude participation in this study
  • Treatment with CYP2D6 substrates that have a narrow therapeutic index. If an alternative treatment cannot be used, a dose reduction of the CYP2D6 substrate may be considered
  • Baseline moderate and severe hepatic impairment (Child Pugh class B \& C)
