Apalutamide and Leuprolide in Intermediate and High-risk Prostate Cancer
Study Details
Study Description
Brief Summary
This is a research study to test an investigational drug (Not FDA approved), Apalutamide given in combination with Leuprolide acetate (FDA approved) in men diagnosed with high-risk prostate cancer who have already selected to have surgery to remove their prostate gland as part of their treatment plan. The main purpose of this study is to determine how tumors make androgens (male hormones), which makes these tumors more aggressive and resistant to hormonal therapy and how a short period of treatment with Apalutamide and leuprolide acetate prior to surgery can affect the production of these hormones in normal and malignant prostate tissue.

Detailed Description
Primary Objective: To evaluate the differential effect of neo-adjuvant leuprolide and Apalutamide on dihydrotestosterone (DHT) concentration in benign prostate tissue based on HSD3B1 genotype.
Secondary Objective(s): To evaluate the differential effect of neoadjuvant leuprolide and Apalutamide on other androgen (testosterone (T), dehydroepiandrosterone (DHEA), androstenediol, 5α-androstanedione (5α-dione), androstenedione (AD), androsterone and 5α-androstanediol) concentrations in benign and malignant prostate tissue based on HSD3B1 genotype.
To compare the level of DHT, T, DHEA, androstenediol, 5α-dione, AD, androsterone and 5α-androstanediol between normal and malignant prostate tissue after neoadjuvant treatment with leuprolide and Apalutamide
To determine the safety of the combination of Leuprolide and Apalutamide administered prior to radical prostatectomy
To evaluate prostatic specific antigen (PSA), FKBP5, TMPRSS2, EZH2, H3K27 and UBE2C tissue expression (via immunohistochemistry (IHC) and quantitative polymerase chain reaction (qPCR)) in benign and malignant prostate tissue after treatment with Leuprolide and Apalutamide.

Arm/Group Description | All participating patients will receive a single dose of leuprolide 7.5 mg intramuscularly (IM) in addition to Apalutamide 240 mg orally daily for four weeks prior to radical prostatectomy (RP). Treatment will be started on day (-28) ± 3 from the scheduled RP date to minimize the variability of treatment duration. Apalutamide may be continued up to and including the day before Leuprolide acetate: Leuprolide acetate, Intramuscular injection - 7.5 mg, one time dose on day (-28) ± 3 Apalutamide: Apalutamide, PO, 240 mg daily, starting day (-28) ± 3 until the day before radical prostatectomy. Apalutamide will be initiated the same day patients receive their leuprolide acetate injection. Radical prostatectomy |
