Safety and Tolerability Study of GIM-122 in Subjects With Advanced Solid Malignancies

This is a Phase 1/2, open label, first-in-human (FIH), multicenter, dose escalation study with enrichments and dose expansion cohorts at RP2D, designed to evaluate the safety, tolerability, PK, pharmacodynamics, and preliminary antitumor activity of GIM-122 administered as a single agent in adults with advanced solid malignancies. This study will be conducted in 2 parts: Phase 1 or Part A (dose escalation and enrichment) and Phase 2 or Part B (dose optimization and cohort expansion).
