Detailed Summary

Researchers conducting this study hope to learn about the safety and effectiveness of combining two study drugs, relacorilant and enzalutamide, plus androgen deprivation therapy (ADT), also known as hormone therapy. This study is for individuals who have been diagnosed with advanced, high-risk prostate cancer and standard therapies available to treat your disease have not been effective. Participation in this research will last about 3 years and 9 months.

Interventions

Relacorilantdrug

Relacorilant is an antiglucocorticoid which is under development by Corcept Therapeutics for the treatment of Cushing's syndrome. It is being used in this study as an experimental drug combined with other treatments for prostate cancer.

Enzalutamidedrug

Enzalutamide, sold under the brand name Xtandi, is a nonsteroidal antiandrogen medication which is used in the treatment of prostate cancer.

Placebo (Sugar Pill)other

This would be a sugar pill consisting of 2 softgels. This is not an experimental drug or treatment.

Androgen Deprivation Therapyother

All participants in this study, who meet the requirements to participate, will get Androgen Deprivation Therapy (ADT; a form of hormone therapy) continuously before their radical prostatectomy surgery. As part of this study, ADT consists of one injection every 1-3 months. In this study, ADT is a gonadotropin releasing hormone (GnRH) agonists or antagonist; the choice of which brand of ADT to use is up to your treating physician. GnRH agonists and antagonists are drugs that lower the production of androgens (male hormones) in your body. Prostate cancer cells usually require androgens, such as testosterone, to grow. Androgen Deprivation Therapy (ADT) has been approved by United Stated Food and Drug Administration (US FDA) to treat patients with prostate cancer but is not approved to treat patients prior to prostatectomy.

Radical Prostatectomyprocedure

Radical prostatectomy is surgery to remove the entire prostate gland and surrounding lymph nodes to treat men with localized prostate cancer.
