A First-in-Human, Open-label, Multicenter, Phase 1 Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics, and Preliminary Efficacy of PYX-201 in Participants With Advanced Solid Tumors
Overview
The primary objectives of this study are to determine the recommended dose(s) of PYX-201 for participants with relapsed/refractory (R/R) solid tumors, and to determine the objective response rate (ORR) in participants treated with PYX-201 as a single agent.
