For female patients without menopause or surgical sterilization: during the treatment period and at least 7 months after the last administration of the drug in the study treatment, agree to abstinence or use effective contraception methods; 8. Volunteer to join the study and sign the informed consent form. Exclusion Criteria: Have received anti-tumor treatment or radiotherapy for any malignant tumor in the past; At the same time, they received anti-tumor therapy in other clinical trials, including endocrine therapy, bisphosphate therapy or immunotherapy; The patient has undergone major surgery unrelated to colorectal cancer within 4 weeks before enrollment, or the patient has not fully recovered from such surgery; Serious heart disease or discomfort, including but not limited to the following diseases: History of diagnosis of heart failure or systolic dysfunction (LVEF<50%) High risk uncontrolled arrhythmia, such as atrial tachycardia, resting heart rate>100 bpm, significant ventricular arrhythmia (such as ventricular tachycardia) or higher grade atrioventricular block (i.e. Mobitz II second degree atrioventricular block or third degree atrioventricular block) Angina requiring anti angina drugs Valvular heart disease with clinical significance ECG showed transmural myocardial infarction Poor control of hypertension (systolic blood pressure>180 mmHg and/or diastolic blood pressure>100 mmHg) Inability to swallow, intestinal obstruction or other factors affecting drug administration and absorption; People known to have a history of allergy to the drug components of this protocol; Have a history of immunodeficiency, including HIV test positive, HBV/HCV test positive, or have other acquired or congenital immunodeficiency diseases, or have a history of organ transplantation; Women in pregnancy and lactation, women with fertility and positive baseline pregnancy test, or women in childbearing age who are unwilling to take effective contraceptive measures during the whole trial period and within 7 months after the last study drug use; Suffer from serious concomitant diseases or other concomitant diseases that may interfere with the planned treatment, or The investigator believes that the patient is not suitable to participate in any other situation of this study.

Brief Summary
Single arm, prospective, exploratory clinical study of Disitamab Vedotin combined with Fruquintinib for advanced colorectal cancer with HER2 expression or mutation that has received at least two standard treatment failures
Detailed Description
Colorectal cancer is the fourth deadliest malignant tumor in the world, and the 5-year survival rate of patients with advanced colorectal cancer is only 12%. In September 2018, furoquentinib was the first approved in China for the treatment of metastatic colorectal cancer patients who failed to receive at least two systematic anti-tumor treatments. The FRESCO trial is a multicenter (28 hospitals in China), randomized, double-blind and placebo controlled phase III trial, The median OS of patients receiving furoxigenib was 9.3 months, while the mOS of patients receiving placebo was 6.57 months (HR=0.65, 95% CI: 0.51~0.83, P<0.001); As a secondary endpoint, mPFS was 3.71 and 1.84 months (HR=0.26, 95% CI: 0.21~0.34, P<0.001). In order to further improve the efficacy, it is necessary to continue to explore the combined treatment strategy of furoquentinib: combined chemotherapy, other targeted treatment and local treatment may benefit more CRC patients. HER2 amplification or overexpression was found in 2%~6% of patients with advanced or metastatic colorectal cancer. In the past decade, several studies have identified it as a potential target for the treatment of HER2 positive colorectal cancer, and it has been written into the guidelines for posterior line therapy. The prognostic value of HER2 overexpression in advanced colorectal cancer is still unclear. The anti-tumor activity of dual targeted HER2 treatment schemes, such as Patuzumab+Trastuzumab, Trastuzumab+Tucatinib, Trastuzumab+Lapatinib, has been significantly increased, which has been confirmed in clinical studies. Vidiximab contains a new humanized anti HER2 antibody Disitamab, which is coupled to monomethylolestatin E (MMAE) through a cleavable linker. Its antibody has a high affinity for HER2 and can efficiently bind with it and enter cancer cells; The linker is cleavable in the tumor cell membrane, which can rapidly release small molecule cytotoxic drugs, and has a bystander killing effect against heterogeneous tumor cells. This one arm, prospective, open study was designed to explore the efficacy and safety of vidiximab combined with furoquentinib triple line or above in the treatment of advanced colorectal cancer with HER2 expression or mutation.
