Conditions
Summary
This is a single-arm, phase II study of neoadjuvant combination therapy of Androgen Deprivation Therapy (ADT), \[Gonadotropin-Releasing Hormone (GnRH) agonist Leuprolide\], androgen receptor (AR)-antagonist Darolutamide and Pembrolizumab in a stratified high-risk localized prostate cancer cohort, followed by adjuvant treatment with Pembrolizumab (12 cycles) post-radical prostatectomy (RP). Patients with National Comprehensive Cancer Network (NCCN) high-risk non-metastatic prostate cancer (localized or locally advanced) (defined as Gleason ≥8, disease stage \>=cT3a, or PSA l \>20 ng/mL) will be risk-stratified at a biopsy using Decipher, a commercial standard-of-care diagnostic assay. Patients satisfying all three criteria of high-risk genomic characteristics listed below as per the Decipher grid results will be enrolled in the study: 1. Decipher Genomic classifier, GC\>0.6 2. AR activity score/AR-output gene signature (ARoS)\>11.0 3. High Luminal B score/ PAM50 subtype signature

Interventions
Darolutamide 600 mg (2 tablets of 300 mg) twice daily with food, equivalent to a total daily dose of 1200 mg for 16 weeks prior to RP.
Administered at the dose of 200 mg intravenously, every 3 weeks, for a total of 5 cycles prior to RP (Neoadjuvant phase, study weeks 1, 4, 7, 10, 13 \& 16), and every 3 weeks, for a total of 12 cycles post-RP (Adjuvant phase, study weeks, 19, 22, 25, 28, 31, 34, 37, 40 43, 46, 49, \& 52). Total Pembrolizumab cycles=17
Androgen deprivation, GnRH agonist Leuprolide will be administered at a dose of 22.5 mg SQ (Eligard)/IM Lupron every 12 weeks prior to RP (Study weeks, 1 and 13).
