Association of SULT2A1 Locus With Abiraterone Clearance in the Alliance A031201: Randomized Phase III Study of Enzalutamide Compared With Enzalutamide Plus Abiraterone for Metastatic Castration-Resistant Prostate Cancer.

ABSTRACT: Enzalutamide and abiraterone are hormonal treatments that improve survival in metastatic castration-resistant prostate cancer. Identifying genetic variants associated with the clearance of these drugs may aid in improved dosing and outcomes. We performed genetic association studies of enzalutamide and abiraterone oral clearance in the Alliance A031201 clinical trial. Genome-wide genotyping was performed with the primary analysis limited to European-descent participants. Pharmacogene metabolic phenotypes were estimated using PyPGx and Stargazer. Associations of metabolic activity groups for CYP3A4, CYP3A5, CYP2C19 and SLCO1B1 with enzalutamide clearance (N = 706) and CYP3A4, SLCO2B1 and UGT1A4 with abiraterone clearance (N = 323) were tested by linear regression.
