Study Summary

Protocol G200712 is a Phase II, exploratory study to assess the effects of GTx-758 on serum prostate specific antigen (PSA) response ans serum PSA progression in men with Metastatic Castration Resistant Prostate Cancer (mCRPC) on Androgen Deprivation Therapy (ADT) with luteinizing hormone-releasing hormone (LHRH) agonists, LHRH antagonists, or orchidectomy. This study will also assess the venous thromboembolism (VTE) risk of lower doses of GTx-758.

Primary Outcome

The percentage of subjects with a 50% decline from baseline in serum PSA (confirmed by a second serum PSA assessment 30 days later) by Day 90 (with follow up confirmation by Day 120)
