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.
The aim of this study is to evaluate the efficacy of mFOLFOXIRI plus cetuximab and avelumab as first line treatment of patients with initially unresectable and previously untreated RAS wild-type metastatic colorectal cancer (mCRC), in terms of Progression-free Survival.
