This is an open-label, unicentre, single-arm Phase 2 study of encorafenib and cetuximab as rechallenge treatment in patients with BRAF V600E-mutant metastatic colorectal cancer after previous therapy with BRAF inhibitors-based combinations.
The study aims to evaluate the antitumor activity of encorafenib plus cetuximab as a rechallenge strategy measured by progression-free survival rate at 4 months.
Eligible patients (a total of 25) will receive encorafenib 300 mg (four 75 mg capsules) once daily (q.d) in 28-day cycles plus intravenous cetuximab at 500 mg/m2 every 2 weeks (Q2W). Treatment will be administered until progression, unacceptable toxicity, patient request, physician's decision or subsequent anticancer therapy.
