Open-label Phase 1b Study of Ulixertinib and Cetuximab or Ulixertinib in Combination With Cetuximab and Encorafenib in Patients With Unresectable or Metastatic Colorectal Cancer Who Have Previously Received EGFR or BRAF-directed Therapy
M.D. Anderson Cancer Center
Summary
To find the recommended dose of ulixertinib that can be given in combination with cetuximab and/or encorafenib to patients with unresectable/metastatic CRC and who have received EGFR or BRAF-directed therapy in the past.
Description
Primary Objective: The primary objective is to establish the safety, maximally tolerated dose (MTD) and recommended phase 2 dose (RP2D) of small molecule inhibitor ulixertinib when combined with EGFR inhibitor cetuximab. Primary Endpoints: 1. MTD based on number of dose-limiting toxicities (DLTs) 2. RP2D based on MTD Secondary Objectives: 1. To evaluate the safety and efficacy of ulixertinib in combination with cetuximab +/- encorafenib 2. Safety profile per CTCAE v5.0, including term, incidence, severity, and duration of AEs 3. Overall response rate (ORR) and Duration of response (DOR),…
