OUTLINE: Patients are randomized to 1 of 2 cohorts. COHORT 1: Patients receive standard of care LHRH agonist or LHRH antagonist according to the Food and Drug Administration approved dose and schedule in the absence of disease progression or unacceptable toxicity. Starting 4 weeks after initiation of LHRH agonist/antagonist, patients also receive androgen receptor signaling inhibitor (ARSI) per physician's choice for a minimum of 12 weeks in the absence of disease progression or unacceptable toxicity. Patients with a median daily hot flash score ≥ 6 after 12 weeks of therapy may crossover to cohort 2. Patients undergo computed tomography (CT) scan or magnetic resonance imaging (MRI), bone scan, dual x-ray absorptiometry (DEXA) scan and blood sample collection throughout the study. COHORT 2: Patients receive estrogen via four transdermal patches twice weekly (BIW) on days 1, 4, 8, 12, 16, 20, 24 and 28 of cycle 1. Once castrate levels of testosterone are confirmed (\< 20 ng/dL), patients receive three patches BIW on days 1, 4, 8, 12, 16, 20, 24 and 28 of cycles thereafter. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients whose testosterone levels rise above castrate levels at any time while receiving three patches BIW then increase to four patches BIW. Starting 4 weeks after initiation of transdermal estrogen, patients also receive ARSI per physician's choice for a minimum of 12 weeks in the absence of disease progression or unacceptable toxicity. Patients undergo CT scan or MRI, bone scan, DEXA scan and blood sample collection throughout the study. After completion of study treatment, patients are followed up at 30 days and every 6 months for 2 years.
