5. Study Description

Brief Summary
Phase I: Determine the maximum tolerated dose of combination of Regorafenib with Refametinib through a dose escalation study, all tumor types that meet certain inclusion/exclusion criteria can be entered. After the recommended dose is determined, the Phase II portion of the study will evaluate tolerability and efficacy of the combination treatment in patients with breast cancer, lung cancer, or colorectal cancer, respectively.
Detailed Description
Number of treatment-emergent Adverse Events (AEs) will be reported in Adverse Events section. Study was originally designed with both Phase I and Phase II part, but sponsor decided not to conduct Phase 2 part due to strategic portfolio re-prioritization.
