Outcome Measures

Primary Outcomes (2)

  • Plasma PF-06651600 Maximum Plasma Concentration (Cmax)

    The plasma PF-06651600 Cmax was observed directly from data.

    On Day 8 and Day 9 predose, and at 0 (predose), 0.25, 0.5, 1, 2, 4, 6, 8, 12, 16 hours after dose on Day 10, and 24 hours after dose on Day 11.

  • Plasma PF-06651600 Area Under the Concentration-Time Curve From Time 0 to 24 Hours (AUC0-24)

    Plasma PF-06651600 AUC0-24 was determined using a linear/log trapezoidal method.

    On Day 8 and Day 9 predose, and at 0 (predose), 0.25, 0.5, 1, 2, 4, 6, 8, 12, 16 hours after dose on Day 10, and 24 hours after dose on Day 11.

Secondary Outcomes (4)

  • Number of Participants With Treatment-Emergent Adverse Events (TEAEs)

    From Screening (Day -28) through and including up to 35 calendar days after the last administration of investigational product, assessed up to 74 days.

  • Number of Participants With Laboratory Abnormalities

    At Screening Visit 1 and on Days -1, 5, 11 and early termination day.

  • Number of Participants With Vital Signs Data Meeting Pre-specified Criteria

    At screening, on Day 1, Day 5, Day 11 and early termination/discontinuation.

  • Number of Participants With Electrocardiogram (ECG) Data Meeting Pre-specified Criteria

    At screening, on Day -1, Day 11 and early termination/discontinuation.

Study Arms (4)

PF-06651600 Severe Renal Impairment

EXPERIMENTAL

This arm includes participants with severe renal impairment who will receive oral doses of PF-06651600 50 mg on Day 1 through Day 10

Drug: PF-06651600
