In Brief

A Phase 1 clinical trial evaluating Abrocitinib, Omeprazole, and 2 other interventions for Healthy Participants. Completed, enrolled 26 participants across 1 site.

Detailed Summary

This is a Phase 1, open-label, multiple dose, single fixed-sequence, 2-period study to evaluate the effect of abrocitinib on the pharmacokinetics (PK) of caffeine, efavirenz and omeprazole in healthy adult participants. A total of approximately 13 healthy male and/or female participants will be enrolled in the study to obtain at least 12 evaluable participants who complete the study. Participants who withdraw from the study or are considered non-evaluable may be replaced at the discretion of the sponsor. Participants will be screened within 28 days of the first dose of study intervention. Participants will have a phone contact 3 days prior to Day 1 dosing (Day -3) in Period 1 as a reminder to abstain from caffeine-containing products. Participants will be admitted to the clinical research unit (CRU) at least 24 hours prior to Day 1 dosing (Day 1) in Period 1. Participants will remain in the CRU for a total of 15 days and 14 nights. Participants will have a telephone contact between 28-35 calendar days after the last administration of the investigational product.
