简要总结
The study is designed as phase III, randomized, two armed, parallel, double blind (patient and assessor blinded), active controlled, and equivalency clinical trial with primary endpoint of Progression-Free Survival of Cetuximab® (produced by CinnaGen) compared with Erbitux® (Cetuximab, the reference drug) in patients with RAS wild-type Metastatic Colorectal Cancer with the allocation ratio of 2:1.Patients who met the following criteria could be recruited to receive the mentioned intervention randomly. Inclusion criteria: Male or female older than 18 years old, histologically confirmed adenocarcinoma of the colon or rectum which is metastatic, having one or more bi-dimensionally measurable lesions as defined by RECIST criteria, tumor that could not be resected for curative purposes,ECOG performance status score of 2 or less,life expectancy of longer than 3 months (clinical assessment),evidence of tumor EGFR expression (expanded wild-type RAS),adequate organ and marrow function as defined:
ANC ≥ 1,500/mm3 Plt ≥ 100,000/mm3 Hb ≥ 9 g/dL (may have had blood transfusions) AST/ALT ≤ 2.5 IULN or ≤ 5 IULN with known liver metastases Total bilirubin ≤ 1.5 IULN Serum Creatinine ≤ 1.5 IULN INR ≤ 1.5 and PTT ≤ 1.5 IULN

Patients who have previous exposure to an anti-EGFR therapy or irinotecan-based chemotherapy, radiotherapy, surgery (excluding previous diagnostic biopsy), or any investigational drug in the 30-day period before the start of treatment in our trial will be excluded from the study. Also, female patients who are pregnant or lactating, and patients with any history of another primary malignancy in the past five years, with the exception of non-melanoma skin cancer, and carcinoma in situ of uterine cervix, and patients with inability to comply with the study and/or follow up procedures will be excluded.The primary endpoint of the study is Progression-Free Survival (PFS) defined as the time from randomization to disease progression or death from any cause. The secondary endpoints of the study are Overall Survival (OS) defined as the time from date of randomization to date of death due to any cause, Objective Response Rate (ORR) defined as the sum of partial and complete responses, according to RECIST criteria and Time to Treatment Failure (TTF) is defined as the time from the date of randomization to the date of each of the following:
The treatment modalities did not destroy or modify the cancer cells, The tumor either became larger (disease progression) or stayed the same size after treatment, Discontinuation of treatment, Death from any cause
Safety and Immunogenicity will also be assessed during the study.

盲法说明
Both of the drugs used in the study are indistinguishable for patients and their respective curative staff because they are similar in size and shape of the vials, caps, aluminum sealing and paints, and it is not possible to distinguish the type of brand from the appearance of the vials. Additionally, people who are evaluating the results and analyzing data are not aware of the type of patient grouping.
