Participants will receive a single oral dose cocktail containing 0.25 mg digoxin and 10 mg rosuvastatin on Day 1 and 64. A single oral dose of placebo to match enzalutamide will be given on Day 1 and 160 mg enzalutamide once daily on Days 8 through 71.

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.

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.

A Phase 1 Open-label 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

Access to anonymized individual participant level data will not be provided for this trial as it meets one or more of the exceptions described on www.clinicalstudydatarequest.com under "Sponsor Specific Details for Astellas."

Cmax will be recorded from the pharmacokinetic (PK) plasma samples collected.

AUClast will be recorded from the pharmacokinetic (PK) plasma samples collected.

AUCinf will be recorded from the pharmacokinetic (PK) plasma samples collected.

Adverse events (AEs) will be coded using medical dictionary for regulatory activities (MedDRA).

An AE is any untoward medical occurrence in a participant administered an Investigational Product (IP), and which does not necessarily have to have a causal relationship with this treatment. An AE can therefore be any unfavorable and unintended sign (including an abnormal laboratory finding), symptom, or disease temporally associated with the use of IP whether or not considered related to the IP.

An AE is considered "serious" if the event: results in death; is life-threatening; results in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions; results in congenital anomaly or birth defect; requires inpatient hospitalization (except for planned procedures)or leads to prolongation of hospitalization (except if prolongation of planned hospitalization is not caused by an AE); or other medically important events.

Participants received enzalutamide 160 milligrams (mg) capsules, orally QD during double blind treatment period until disease progression, unacceptable toxicity, or any other discontinuation criterion was met. Eligible participants received enzalutamide 160 mg capsules, orally QD during open label period until disease progression, unacceptable toxicity, or any other discontinuation criterion was met. Median treatment duration was 64 days.

Participants received enzalutamide matching placebo orally, once daily (QD) during double blind treatment period until disease progression, unacceptable toxicity, or any other discontinuation criterion was met. Median treatment duration was 64 days.

Executive Medical Director

The purpose of the study was to evaluate the efficacy of enzalutamide in participants with advanced hepatocellular carcinoma (HCC) as measured by overall survival (OS).

This study also evaluated the safety of enzalutamide; pharmacokinetics of enzalutamide and the active metabolite N-desmethyl and Progression Free Survival (PFS) of enzalutamide as compared to placebo in participants with advanced HCC.

A Study to Assess the Efficacy and Safety of Enzalutamide in Subjects With Advanced Hepatocellular Carcinoma

A Phase 2, Randomized, Double-Blind, Placebo-Controlled Study to Assess the Efficacy and Safety of Enzalutamide in Subjects With Advanced Hepatocellular Carcinoma

OS was defined as the time from the date of randomization until the documented date of death from any cause. Participants who were still alive at the time of the data cut-off date was censored on the last date known to be alive or at the data cutoff date, whichever occurs first. Results based on Kaplan-Meier estimates.

Safety was assessed by AEs, which included abnormalities identified during a medical test (e.g. laboratory tests, vital signs, electrocardiogram, etc.) if the abnormality induced clinical signs or symptoms, needed active intervention, interruption or discontinuation of study medication or was clinically significant. A treatment-emergent AE (TEAE) was defined as an AE observed after starting administration of the study drug up to 30 days after last dose of study drug or initiation of new treatment, whichever comes first. AEs were considered as serious if resulted in in death, was life-threatening resulted in persistent or significant disability/incapacity or substantial disruption of the ability to conduct normal life functions, resulted in congenital anomaly or birth defect, required inpatient hospitalization or led to prolongation of hospitalization and other medically important events.

Blood samples were collected for analysis.

PFS was defined as the time from the date of randomization until the date of documented radiographic disease progression according to Response Evaluation Criteria in Solid Tumors (RECIST) 1.1 as determined by the investigator or death from any cause on study, whichever occurred first. The earliest of the censoring times was used: Participants with (1) no evaluable postbaseline imaging assessments or did not die were censored at the randomization date; (2) no radiographical progression or did not die before analysis cutoff date were censored at the last radiological assessment date before analysis cutoff date; (3) with no radiographical progression or did not die before new HCC treatment was censored at the last radiological assessment date before start of new HCC treatment. Based on Kaplan-Meier.

Participants received enzalutamide matching placebo orally, QD during double blind treatment period until disease progression, unacceptable toxicity, or any other discontinuation criterion was met. Median treatment duration was 64 days.
