AVELUMAB and CETUXIMAB and mFOLFOXIRI as Initial Therapy for Unresectable Metastatic Colorectal Cancer Patients

This is a prospective, open-label, multicentric phase II single-arm trial in which patients with initially unresectable and previously untreated RAS wild-type mCRC will receive induction treatment with mFOLFOXIRI plus cetuximab and avelumab up to 12 cycles followed by maintenance with 5-FU/LV plus cetuximab plus avelumab until disease progression, unacceptable toxicity or patient's refusal. The second- and subsequent lines of treatment will be at investigators' choice.
