- Aspartate aminotransferase (AST) or alanine aminotransferase (ALT) < 3 times ULN or < 5 times ULN if patient has documented liver metastases
- Creatinine < 1.5 times ULN
- INR < 1.5 times ULN, or if on warfarin, can safely transition off for biopsy
- Willing to donate blood for research at 4 time points
- Written informed consent obtained prior to biopsies and blood samples
- Agreement to exercise appropriate use of contraception. Subjects should use 2 acceptable methods of birth control (one of which must include a condom as a barrier method of contraception) starting at the time of screening for an enzalutamide study and continuing throughout the course of treatment and for at least three months after enzalutamide is discontinued.
You may not qualify if…
- Current or previously treated brain or leptomeningeal metastases
- History of seizures
- Prior treatment with an anti-androgen (abiraterone, ARN-509, bicalutamide, enzalutamide, ODM-201, TAK-448, TAK-683, TAK-700, VT-464)
