Effect of Multiple Doses of Itraconazole on the Pharmacokinetics of a Single-Dose of PF-06651600 in Healthy Participants

Summary

This study will estimate the impact of a strong CYP3A4 inhibitor (itraconazole) on the pharmacokinetics of an investigational product (PF-06651600) in healthy adult participants. This is an open-label, fixed sequence two period study with healthy participants that will receive a single dose of PF-06651600 alone and co-administered with multiple doses of itraconazole at a single center. Participants will be screened within 28 days of the first dose of the investigational products and if entry criteria are met, the participant will report to the clinic on the day before the Day 1 visit. On Day 1 of Period 1, each participant will receive a 30 mg dose of PF-06651600 and PK samples will be collected for 48 hours. In Period 2, participants will receive itraconazole solution from Day 1-5. On Day 4 of Period 2 the participant will receive 30 mg of PF-06651600 with the itraconazole. PK samples will be collected up to 48 hours after the PF-06651600 dose. Participants will be confined for a total of 9 days in the clinic. The participant will be followed up by phone contact.
