Study Endpoints

Primary Endpoints

Part A: PF-06882961 Maximum Observed Concentration (Cmax)
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16 and 24 hours post-dose on Day 1

Cmax for PF-06882961 was observed directly from data.

Part A: PF-06882961 Area Under the Plasma Concentration-time Profile From Time 0 to the Time 24 Hours Post-dose (AUC24)
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 16 and 24 hours post-dose on Day 1

AUC24 for PF-06882961 was determined by Linear/Log trapezoidal method.

Part B: PF-06865571 Cmax on Day 1 and Day 47
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24 and 48 hours post-dose

Cmax for PF-06865571 was observed directly from data on Day 1 and Day 47.

Part B: PF-06865571 Area Under the Plasma Concentration-time Profile From Time 0 to the Time of the Last Quantifiable Concentration (AUClast) on Day 1 and Day 47
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24 and 48 hours post-dose

AUClast for PF-06865571 was determined by Linear/Log trapezoidal method on Day 1 and Day 47.

Part B: PF-06865571 Area Under the Plasma Concentration-time Profile From Time 0 Extrapolated to Infinite Time (AUCinf) on Day 1 and Day 47
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, 14, 16, 24 and 48 hours post-dose

AUCinf for PF-06865571 was calculated as AUClast + (Clast\*/kel) on Day 1 and Day 47. Clast\* was the predicted plasma concentration at the last quantifiable time point estimated from the log-linear regression analysis and kel was the elimination rate constant.

Part B: PF-06882961 Cmax on Day 46 and Day 61
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, and 24 hours post-dose

Cmax for PF-06882961 was observed directly from data on Day 46 and Day 61.

Part B: PF-06882961 Area Under the Plasma Concentration-time Profile From Time 0 to the Time 12 Hours Post-dose (AUC12) on Day 46 and Day 61
0 (prior to dosing), 0.5, 1, 2, 3, 4, 6, 8, 10, 12, and 24 hours post-dose

AUC 12 for PF-06882961 was determined by Linear/Log trapezoidal method on Day 46 and Day 61.
