Clinical Trials Related to Zytiga (Abiraterone)

A Study of HSP90 Inhibitor AT13387 Alone or in Combination With Abiraterone Acetate [Recruiting]
A 2-part, Phase 1-2, open-label, parallel group, randomized study in patients with Castration-Resistant Prostate Cancer (CRPC) who are no longer responding to treatment with abiraterone and steroids. In Part A (Phase 1), patients will continue to receive the same doses of abiraterone and steroids they were receiving prior to study entry and will be randomized to receive 1 of 2 different treatment regimens of AT13387 in combination with abiraterone. Once the best regimen is established in Part A, based on safety and antitumor activity, patients will be randomized to the selected treatment regimen and dose of AT13387 in combination with abiraterone or AT13387 alone in Part B (Phase 2).

3-arm Study of Abiraterone Acetate Alone, Abiraterone Acetate Plus Degarelix, a GnRH Antagonist, and Degarelix Alone for Patients With Prostate Cancer With a Rising PSA or a Rising PSA and Nodal Disease Following Definitive Radical Prostatectomy [Recruiting]
The United States Food and Drug Administration (FDA) recently approved the oral drug abiraterone acetate (Zytiga ®) in combination with prednisone (a steroid) to treat patients with metastatic castration-resistant prostate cancer who have received prior docetaxel (chemotherapy). Degarelix (Firmagon ®), a testosterone lowering agent given as a monthly injection, is FDA approved for the treatment of patients with advanced prostate cancer. The purpose of this study is to evaluate abiraterone acetate and prednisone in combination with degarelix as a possible treatment for PSA recurrent prostate cancer as compared to abiraterone acetate alone and degarelix alone. This will be the first time these drugs will be used together.

Pharmacodynamic Study of Abiraterone in the Treatment of Advanced Prostate Cancer [Not yet recruiting]
The purpose of this study is to evaluate the molecular effects of Abiraterone acetate and prednisone on prostate cancer. Participants will take Abiraterone acetate plus prednisone. While taking these drugs, patients will undergo sampling of cancer: one before treatment and one during treatment. To measure the body's overall response to Abiraterone acetate, the study follows patients for Prostate Specific Antigen (PSA) levels, cancer symptoms, and any side effects.

A Study of Abiraterone Acetate Plus Prednisone With or Without Exemestane in Postmenopausal Women With Estrogen Receptor-Positive (ER+) Metastatic Breast Cancer Progressing After Letrozole or Anastrozole Therapy [Recruiting]
The purpose of this study is to assess the safety and efficacy of oral abiraterone acetate plus oral prednisone and oral abiraterone acetate plus oral prednisone plus oral exemestane, each compared with oral exemestane alone, in postmenopausal women with estrogen receptor-positive (ER+) metastatic (spreading) breast cancer that has relapsed after treatment with letrozole or anastrozole.

A Multicenter Phase I/II Trial of Abiraterone Acetate + BEZ235 in Metastatic, Castration-Resistant Prostate Cancer [Not yet recruiting]
There will be two parts to this clinical research study. The purpose of each part is:

- Phase 1: This part of the study will determine what dose of BEZ235 is safe to give with

a standard dose of abiraterone acetate and prednisone by administering different doses of BEZ235. This will help to find out what effects, good and/or bad, this combination has on CRPC.

- Phase 2: This part of the study will measure the treatment effect of the combination of

BEZ235 and abiraterone acetate/prednisone on CRPC.
