A Study to Evaluate the Effect of [14C]Acp-196 (Acalabrutinib) in Healthy Adult Participants

Acerta Pharma BV14 enrolled

Overview

This study is to determine the absolute bioavailability of oral acalabrutinib and intravenous (IV) PK of \[14C\]ACP-196.

This is 2-cohort study. Screening period will be within 28 days before the dose. In the treatment period, participants in Cohort 1 will receive a single 100 mg oral capsule dose of acalabrutinib and at 58 minutes postdose of acalabrutinib will receive a single microtracer (\<10 μg; \<=1 μCi) \[14C\]ACP-196 as a 5 mL IV push over 2 minutes; and participants in Cohort 2 will receive a single 100 mL oral solution of acalabrutinib (1 mg/mL oral solution containing a microtracer dose (\<10 μg; \<=1 μCi) of \[14C\]ACP-196). Cohort 1 participants will be confined continuously from Check-in until Day 5 and Cohort 2 participants will be confined continuously from Check-in until Day 8.
