Trial Design

3Treatment groups
Experimental Treatment
Group I: PF-06651600 Moderate Hepatic ImpairmentExperimental Treatment1 Intervention
This arm includes participants with moderate hepatic impairment who will receive oral doses of PF-06651600 30 mg on Day 1 through Day 10.
Group II: PF-06651600 Mild Hepatic ImpairmentExperimental Treatment1 Intervention
This arm is in Part 2 which will be conducted if the decision criterion to proceed to Part 2 is met. The arm includes participants with mild hepatic impairment who will receive oral doses of PF-06651600 30 mg on Day 1 through Day 10.
Group III: PF-06651600 Healthy participantsExperimental Treatment1 Intervention
This arm includes healthy adult participants who will receive oral doses of PF-06651600 30 mg on Day 1 through Day 10.
