A Renal Impairment Study for PF-06651600

Study Overview
=================
Brief Summary
-----------------
This is a Phase 1 non-randomized, open-label, parallel cohort study of PF-06651600 in subjects with severe renal impairment and subjects without renal impairment (Part 1) and in subjects with mild and moderate renal impairment (Part 2).

Detailed Description
-----------------
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-06651600 after multiple oral doses of 50 mg daily. 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 11 will be a maximum of 39 days and from Screening visit to Follow-up/Contact Visit will a maximum of 73 days.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| 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 Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Number of Participants With Treatment-Emergent Adverse Events (TEAEs) | An AE was any untoward medical occurrence in a clinical study participant, temporally associated with the use of study intervention, whether or not considered related to the study intervention. An AE is considered a TEAE is the event started during the effective duration of treatment. All events that started on or after the first dosing day and time/start time, if collected, but before the last dose plus the lag time were flagged as TEAEs. An AE was considered treatment-related if the causality of the AE was assessed to be the investigational product. The causality of AEs was assessed by the investigator using clinical judgment. | 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 | Safety laboratory assessments include clinical chemistry, hematology and urinalysis. Serum creatinine was only assessed on Screening visit 2 and on Day 2 and Day 8 for eGFR assessment. The number of participants with laboratory test abnormalities without regard to baseline abnormality was reported. | 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 | Vital signs evaluations included supine blood pressure (BP), pulse rate, and temperature. Criteria for vital signs values included: supine diastolic BP >= 20 mmHg increase from baseline, supine systolic BP >= 30 mmHg increase from baseline, supine diastolic BP >= 20 mmHg decrease from baseline, and supine systolic BP >= 30 mmHg decrease from baseline. | At screening, on Day 1, Day 5, Day 11 and early termination/discontinuation. | 
| Number of Participants With Electrocardiogram (ECG) Data Meeting Pre-specified Criteria | ECG criteria included PR, QT, and QTc intervals and QRS complex. Participants with absolute data value meeting the following criteria were reported: aggregate PR interval value >= 300 msec, aggregate QRS duration value >= 140 msec, absolute QTcF interval value >450 msec and <= 480 msec, or >480 msec and <=500 msec, or >500 msec. | At screening, on Day -1, Day 11 and early termination/discontinuation. |
