Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this study is to characterize the effect of hepatic impairment on the pharmacokinetic(s) (PK) of PF-06651600 following administration of multiple once daily doses of PF-06651600. The safety and tolerability of PF-06651600 will also be evaluated in this study.
