Anlotinib Hydrochloride Capsules Combined With CAPEOX in RAS and BRAF Wild-type mCRC Patients

This is an Open, Single Arm, Exploratory and Phase II Clinical Trial of Anlotinib Hydrochloride Capsules Combined With CAPEOX in RAS and BRAF wild-type patients with Metastatic Colorectal Carcinoma(CRC) as 1st Therapy. After 6 cycles of combined therapy, patients will receive capecitabine and anlotinib as maintenance therapy until tumor progression.In order to observe and evaluate the efficacy and safety of Anlotinib Hydrochloride Capsules combined with CAPEOX in treatment of patients with Metastatic Colorectal Carcinoma(mCRC).Primary Efficacy Endpoint: Objective Response Rate (ORR), Secondary Efficacy Endpoints: Progression free survival (PFS) (According to RECIST Version 1.1), Disease Control Rate (DCR) and duration of response(DoR). Safety and tolerance will be evaluated by incidence, severity and outcomes of AEs and categorized by severity in accordance with the NCI CTC AE Version 4.0.
