Summary

The purpose of the study is to evaluate the safety and efficacy of talazoparib in
combination with enzalutamide compared with placebo in combination with enzalutamide in
participants with DDR-deficient mCSPC.

Objectives

The study will have 5 periods: prescreening, screening, double-blind treatment, safety
follow-up, and long-term follow-up.

Approximately 550 men with mCSPC will be randomized. Eligible participants will be
randomly assigned to either of 2 treatment groups as follows:

- Talazoparib in combination with enzalutamide.

- Placebo capsules identical in appearance to talazoparib capsules in combination with
enzalutamide.

Talazoparib or identical placebo treatment will be blinded. Enzalutamide (160 mg/day)
will be open label. The dose of talazoparib/placebo to be given in combination with
enzalutamide is 0.5 mg once daily. Participants with moderate renal impairment (eGFR
30-59 mL/min/1.73 m2 by the MDRD equation) at screening may be enrolled and the
talazoparib/placebo dose will be 0.35 mg once daily.
