Detaillierte Beschreibung
This is a first-in-human, Phase 1/2, multicenter, open-label study designed to evaluate the safety, tolerability, PK, pharmacodynamics, immunogenicity, and antitumor activity of XTX501, an investigational bispecific PD-1/masked IL-2 in participants with metastatic NSCLC and select advanced solid tumors.
Phase 1, Part 1A will examine XTX501 monotherapy in a Bayesian Optimal Interval design to determine the maximum tolerated dose up to 10 dose regimens.
Phase 1, Part 1B will further evaluate the safety and antitumor activity of XTX501 at dose regimens under consideration for the recommended Phase 2 dose(s).
Phase 2 will further evaluate the efficacy of the selected recommended Phase 2 dose(s).
