Clinical Trial of a Rapidly Cycling, Non-Cross Reactive Regimen of Approved Therapeutic Agents to Treat Prostate Cancer

Condition: Prostate Cancer


  • Drug: Abiraterone acetate
  • Drug: Prednisone
  • Drug: Radium-223 dichloride
  • Drug: cabazitaxel
  • Drug: Carboplatin
  • Drug: Enzalutamide

Purpose: The purpose of this study is to determine the clinical benefits of using a rapidly cycling, non-cross reactive regimen of FDA-approved prostate cancer therapeutic agents in the management of castration resistant prostate cancer. The hypothesis is that the identification of optimal combinations and sequencing of therapies can help prevent or delay the development of therapeutic drug resistance, and can be safely tolerated.

Exclusion Criteria:

  • History of uncontrolled seizure disorder
  • Clinically significant cardiovascular disease including: 1. Myocardial infarction or uncontrolled angina within 6 months 2. Congestive heart failure New York Heart Association (NYHA) class 3 or 4, or patients with history of congestive heart failure NYHA class 3 or 4 in the past 3. Uncontrolled hypertension as indicated by a resting systolic blood pressure > 170 mmHg or diastolic blood pressure > 105 mmHg at the screening visit
  • Have used or plan to use from 30 days prior to enrollment through the end of the study medication known to lower the seizure threshold or prolong the QT interval

  • Prior use of abiraterone acetate, enzalutamide, docetaxel, cabazitaxel, carboplatin, or radium-223 for the treatment of castration-resistant disease
  • Prior docetaxel use in the hormone-sensitive disease setting is allowed, but must be completed ≥ 4 weeks prior to enrollment
  • Prior sipuleucel-T use is allowed, but must be completed ≥ 4 weeks prior to enrollment
  • Concurrent use of zoledronic acid or denosumab is allowed on study
