Patient View

This Phase 1/2a study evaluates mirdametinib and BGB-3245 in adults with advanced solid tumors unresponsive to prior therapies. Participants must have MAPK pathway mutations and meet specific criteria, including measurable disease and adequate organ function. Both drugs are administered orally. Eligibility includes age ≥18, ECOG ≤2, and tumor tissue availability.

Patient Parameters

Program Overview

A Phase 1/2a open-label, multicenter, dose escalation and expansion study of mirdametinib in combination with BGB-3245 in adult participants with histologically confirmed, advanced (American Joint Committee on Cancer (AJCC) Stage III or IV) metastatic or unresectable solid cancer that is refractory to or has progressed during or after at least 1 line of appropriate prior systemic anti-cancer therapy including chemotherapy, immunotherapy, or appropriate targeted therapy, or for which there is no treatment available, or prior standard of care therapy was not tolerated.
