A Study in Healthy Subjects to Assess Bioavailability (Proportion of a Drug Which Enters the Circulation to Have an Active Effect) of Acalabrutinib Tablet and Protonpump Inhibitor Effect (Members of a Class of Medications That Inhibits in Gastric Acid Production) for Rabeprazole

Summary

This Phase 1 study is being conducted to support the clinical development of acalabrutinib in hospitalized patients who are unable to swallow acalabrutinib tablet or capsule due to respiratory failure, eg, they may require endotracheal intubation for ventilator support and nasogastric (NG) tube placement, and it is important to have a clinically acceptable method to administer acalabrutinib via NG tube. Part 1 of the study is designed to evaluate relative bioavailability by comparing the pharmacokinetic (PK) of AT suspension in water administered via NG tube with the PK of acalabrutinib capsule suspension in flat COCA-COLA administered via NG tube. Additionally, the PPI effect will be evaluated by comparing the PK of AT suspension in water administered via NG tube plus rabeprazole with the PK of AT suspension in water administered via NG tube. Part 2 of the study is designed to evaluate the effect of NG administration on AT by comparing the PK of AT suspension in water administered via NG tube with the PK of AT orally administered with water.
