Spots Global Cancer Trial Database for A Study to Evaluate the Effect of Multiple Doses of Enzalutamide on the Pharmacokinetics of Substrates of P-glycoprotein (Digoxin) and Breast Cancer Resistant Protein (Rosuvastatin) in Male Subjects With Prostate Cancer

Study Description

Brief Summary: The primary purpose of this study is to determine the effect of multiple once daily administrations of enzalutamide on the pharmacokinetics of a single dose of digoxin (P-glycoprotein (P-gp) substrate) and rosuvastatin (breast cancer resistant protein (BCRP) substrate) in participants with prostate cancer. This study will also evaluate the safety and tolerability of multiple once daily administrations of enzalutamide alone and in combination with a single dose of digoxin (P-gp substrate) and rosuvastatin (BCRP substrate) in participants with prostate cancer, as well, assess the pharmacokinetics of enzalutamide and its active metabolite.

Detailed Description: Eligible participants will be admitted to the clinical unit on day -1. Participants may be discharged from the clinical unit on day 2 on the condition that all required assessments have been performed and that there are no medical reasons for a longer stay in the clinical unit and participants are able and willing to return to the clinical unit on days 3 to 8 for daily pharmacokinetic sampling. Or, participants may choose to remain in the clinical unit up to the 168 hour postdose (day 8) pharmacokinetic sample collection. Participants will return to the clinical unit on day 35 for an ambulant visit and will be admitted to the clinical unit on day 63. Participants may be discharged from the clinical unit on day 65 on the condition that all required assessments have been performed and that there are no medical reasons for a longer stay in the clinical unit and participants are able and willing to return to the clinical unit on days 66 to 71 for daily pharmacokinetic sampling. Or, participants may choose to remain in the clinical unit up to the 168 hour postdose (day 71) pharmacokinetic sample collection. From day 72 onwards, participants experiencing clinical benefit (determined by the investigator in consultation with the physician responsible for treating the participants' prostate cancer) may roll over into an open label, single arm extension study. Only participants who will be enrolled into the extension study will continue to receive enzalutamide until any discontinuation criterion occurs per the extension study protocol.
