1 Phase I clinical trial of a selective inhibitor of CYP17, abiraterone acetate, confirms that castration-resistant prostate cancer commonly remains hormone driven. Abiraterone Acetate cytochrome P450 family 17 subfamily A member 1 Homo sapiens
2 To evaluate this, a trial of abiraterone acetate-a potent, selective, small-molecule inhibitor of cytochrome P (CYP) 17, a key enzyme in androgen synthesis-was pursued. Abiraterone Acetate cytochrome P450 family 17 subfamily A member 1 Homo sapiens
3 Abiraterone acetate administration was associated with increased levels of adrenocorticotropic hormone and steroids upstream of CYP17 and with suppression of serum testosterone, downstream androgenic steroids, and estradiol in all patients. Abiraterone Acetate cytochrome P450 family 17 subfamily A member 1 Homo sapiens
4 CONCLUSION: CYP17 blockade by abiraterone acetate is safe and has significant antitumor activity in CRPC. Abiraterone Acetate cytochrome P450 family 17 subfamily A member 1 Homo sapiens
