Brief Summary
This is a Phase 1b/2 protocol to evaluate pharmacokinetics, safety, efficacy, and pharmacodynamics of PF-06801591, a programmed death-1(PD-1) antagonist monoclonal antibody (mAb) in participants with advanced malignancies. This study consists of 2 parts: Phase 1b part (dose escalation and dose expansion) in patients with advanced malignancies in Asia and a global Phase 2 part in non small cell lung cancer (NSCLC) patients.

Outcome Measures
Primary Outcomes (3)
Phase 1b: Number of Participants With Dose-Limiting Toxicities (DLT)
This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with first line (1L) and second line (2L) non-small cell lung cancer (NSCLC) (Phase 2). For the Phase 1b, any of the following AEs occurring during the DLT observation period (the first cycle of treatment) which were attributable to the investigational product were classified as DLTs: Grade 5 AE not clearly due to the underlying disease or extraneous causes; Hematologic toxicity; Non-Hematologic Toxicity; Delay of ≥ 3 weeks in receiving the next scheduled administration due to persisting treatment-related toxicities.
Phase 1b: at the end of cycle 1 (28 days) for the PF-06801591 300 mg SC Q4W arms, and (42 days) for the PF-06801591 600 mg SC Q6W arms
Phase 2: AUCτ of PF-06801591 at Steady State
This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with 1L and 2L NSCLC (Phase 2). AUCτ is area under the plasma concentration-time profile from time zero to the next dose (at steady state, starting at Week 12). (τ = X days, where X = 28 days for Q4W regimen and 42 days for Q6W regimen)
Phase 2: Cycle 4 Day 1, 8, 15, 22 and Cycle 5 Day 1 for the PF-06801591 300 mg SC Q4W arm, and Cycle 3 Day 1, 8, 15, 29 and Cycle 4 Day 1 for the PF-06801591 600 mg SC Q6W arm
Phase 2: Ctrough of PF-06801591 at Steady State, at Week 12
This study included Asian participants with advanced solid tumors (Phase 1b) and global participants with 1L and 2L NSCLC (Phase 2). Steady state Ctrough is pre-dose concentration following multiple dosing at steady state (Week 12)
Phase 2: Cycle 4 Day 1 for the PF-06801591 300 mg SC Q4W arm, and Cycle 3 Day 1 for the PF-06801591 600 mg SC Q6W arm
Secondary Outcomes (9)
Number of Participants With Treatment-Emergent Adverse Events
Phase 1b/2: On-treatment period is defined as the time from the first dose of study treatment through minimum (30 days + last dose of study treatment, start day of new anti-cancer drug therapy - 1 day).
Number of Participants With Laboratory Abnormalities
Phase 1b/2: On-treatment period is defined as the time from the first dose of study treatment through minimum (30 days + last dose of study treatment, start day of new anti-cancer drug therapy - 1 day).
Pharmacokinetic Parameters: AUCτ After First Dose
Phase 1b/2: For the PF-06801591 300 mg SC Q4W arms, Cycle 1 Day 1, 8, 15, 22, Cycle 2 Day 1; for the PF-06801591 600 mg SC Q6W arms, Cycle 1 Day 1, 8, 15, 29, Cycle 2 Day 1
Pharmacokinetic Parameters: Ctrough After First Dose
Phase 1b/2: Cycle 2 Day 1 for all Arms
Pharmacokinetic Parameters: Ctrough at Steady State
Phase 1b/2: For the PF-06801591 300 mg SC Q4W arms, Day 1 of Cycle 4; for the PF-06801591 600 mg SC Q6W arms, Day 1 of Cycle 3
