Phase 1 |
Detailed Description
This is a 2-period study done under fasting conditions. Participants will receive an oral wireless motility/pH capsule (SmartPill®) followed immediately by a single 100 mg oral dose of acalabrutinib on Day 1 of Period 1 and Period 2 (ie, Day 1 and Day 4, respectively). There will be 72 hours of washout between Day 1 dosing of each period. Participants will be contacted approximately 14 days after the last dose of study drug for adverse events.
