Summary

This randomized pilot phase I trial studies the side effects of dietary fat levels and abiraterone acetate uptake in patients with metastatic hormone-resistant prostate cancer. Abiraterone acetate may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Eating a low or high fat diet may increase the uptake of abiraterone acetate.

Eligible Conditions
  • Prostate Cancer

Trial Design

2Treatment groups
Experimental Treatment
Group I: Arm II (abiraterone acetate, high then low fat breakfast)Experimental Treatment5 Interventions
Patients receive abiraterone acetate as in Arm I. Patients eat a high fat breakfast on day 3, and a low fat breakfast on day 10.
Group II: Arm I (abiraterone acetate, low then high fat breakfast)Experimental Treatment5 Interventions
Patients receive standard dose abiraterone acetate PO QD (held on days 2, 3, 9, and 10), and low-dose abiraterone acetate PO QD on days 3 and 10. Patients eat a low fat breakfast on day 3 and a high fat breakfast on day 10.
