Summary
This is a safety, pharmacokinetic and pharmacodynamic study designed to estimate the maximum tolerated dose (MTD), and determine the Recommended Phase 2 Dose (RP2D) of PF-05082566, a 4-1BB agonist monoclonal antibody (mAb), in combination with MK-3475, a PD-1 inhibitor in patients with solid tumors.
