This is a Phase 1/2, multi-center, open-label basket study designed to evaluate the safety and anti-tumor activity of IDE196 in patients with solid tumors harboring GNAQ or GNA11 (GNAQ/11) mutations or PRKC fusions, including metastatic uveal melanoma (MUM), cutaneous melanoma, colorectal cancer, and other solid tumors.
Phase 1 (dose escalation - monotherapy) will assess safety, tolerability and pharmacokinetics of IDE196 via standard dose escalation scheme and determine the recommended Phase 2 dose. Safety and anti-tumor activity will be assessed in the Phase 2 (dose expansion) part of the study.
Phase 1 Tablet and Food Effect Pharmacokinetic (PK) Substudy will assess the PK profile of IDE196 tablet and evaluate the effects of food on the PK profile of IDE196 tablet
Phase 1 (dose escalation - binimetib combination) will assess safety, tolerability and pharmacokinetics of IDE196 and binimetinib via standard dose escalation scheme and determine the recommended Phase 2 dose. Safety and anti-tumor activity will be assessed in the Phase 2 (dose expansion) part of the study.
Phase 1 (dose escalation - crizotinib combination) will assess safety, tolerability and pharmacokinetics of IDE196 and crizotinib via standard dose escalation scheme and determine the recommended Phase 2 dose. Safety and anti-tumor activity will be assessed in the Phase 2 (dose expansion) part of the study.
