This is a Phase 1 non-randomized, open-label, parallel cohort, multi-site study to investigate the effect of renal impairment on the pharmacokinetics, safety and tolerability of PF-06700841 after a single oral dose of 30 mg. Subjects will be selected and categorized into normal renal function or renal impairment groups based on their estimated glomerular filtration rate. Part 1: A total of approximately 16 subjects will be enrolled; approximately 8 subjects with severe renal impairment and approximately 8 with normal renal function. After statistical evaluation of results from Part 1, Part 2 may be conducted with approximately 8 subjects each with moderate and mild renal impairment. The total duration of participation from Screening visit to Day 4 will be a maximum of 32 days and from Screening visit to Follow-up/Contact Visit will a maximum of 67 days.
