Brief summary: The objective is to investigate the efficacy and safety of raltitrexed combined with Irinotecan (SALIRI) based regimen as first-line treatment for advanced metastatic colorectal cancer(mCRC).

Detailed description: A number of previous studies show that raltitrexed combined with oxaliplatin/irinotecan as first-line treatment for advanced metastatic colorectal cancer(mCRC) is safe and effective. Chinese registered clinical studies show that raltitrexed combined with oxaliplatin has better safety and overall clinical efficacy than 5-FU combined with oxaliplatin in the treatment of mCRC. However, there is no study data on raltitrexed plus irinotecan (SALIRI) combined with targeted drugs as first-line treatment for mCRC in Chinese patients. This an open-label, multi-center, and prospective phase Ⅱ study enroled mCRC patients treated with first-line raltitrexed plus Irinotecan (SALIRI) based chemotherapy. Plan to to enroll 90 patients. The primary outcome is Overall Response Rate(ORR). The secondary Outcomes are Progression Free Survival (PFS)，Overall Survival (OS)，disease control rate (DCR)，the occurrence of adverse reactions(AEs)，and Quality of Life \[WHO-QOL\].

Eligibility criteria: Inclusion Criteria:

1. 18-75 years old.
2. Life expectancy ≥ 3 months.
3. Patients with unresectable advanced colorectal cancer confirmed by histology or cytology.
4. Patients with initially treated metastatic colorectal cancer who were assessed to be unable to undergo radical surgery，or recurrence and metastasis more than 6 months after receiving radical surgery adjuvant chemotherapy, and the metastases can not be removed.
5. At least one measurable lesion by CT or MRI according to RECIST1.1 criteria.
6. ECOG 0 \~ 1.
7.

3. History of other malignancies, except cured Basal cell or squamous Cell Carcinoma of the skin and carcinoma in situ of the cervix.
4. Participate in another clinical trial within 30 days prior to admission and receive a research drug and any concomitant therapy containing a research drug.
5. Any of the following events occurred during the first 6 months in Group A: cerebrovascular accident (including stroke or transient ischemic attack) , myocardial infarction, severe/unstable angina, coronary/peripheral artery bypass graft, and congestive heart failure NYHA Grade III or IV, drug-treated or clinically significant Arrhythmia, prolonged Q-T interval of ECG, etc.
6. Bowel obstruction or incomplete bowel obstruction, history of inflammatory bowel disease or extensive Colectomy, 50% or extensive small bowel resection with chronic diarrhea.
7. The presence of an active infection or a concomitant disease that seriously endangers the patient's safety or affects the patient's ability to complete the study.
