Measure
Apalutamide + Leuprolide Acetate
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
