Vitamin E Combined With Fruquintinib and Tislelizumab in Microsatellite Stabilized Metastatic Colorectal Cancer Patients

Recruiting now · Phase 2

Conditions studied: Colorectal Cancer, Microsatellite Stable Colorectal Carcinoma

In brief

The goal of this clinical trial is to learn about efficacy of Vitamin E in combination with Fuquinitinib and Tirelizumab in patients with microsatellite stabilized mCRC who have failed standard therapy. The main question is to explore the survival time, safety and tolerability of the treatment. At the same time, the correlation between biomarkers (including PD-L1 expression, tumor mutation load, lymphocyte subpopulation, cytokines, TCR, intestinal microbes, and others) and the efficacy and drug resistance mechanism will be analyzed, so as to provide reference for the subsequent guidance of the screening of benefit groups.

Serum creatinine ≤ 1.5 times the upper limit of normal, creatinine clearance ≥60ml/min;
International normalized ratio (INR) or prothrombin time (PT) ≤ 1.5 times the upper limit of the normal range, unless the patient is receiving anticoagulant therapy and the PT value is within the intended range for anticoagulant therapy;
Activated partial thromboplastin time (aPTT) ≤ 1.5 times the upper limit of normal;
There were no serious concomitant diseases that could make the survival time less than 5 years;
Negative pregnancy test in female subjects (for female patients of childbearing potential); Infertile female patients;
Male patients of childbearing potential and female patients of childbearing potential and at risk of pregnancy must agree to use adequate contraception for the entire duration of the study and for 12 months after receiving treatment with the protocol;
Signed and dated informed consent indicating that the patient has been informed about all relevant aspects of the study;
Patients who are willing and able to comply with the visit schedule, treatment plan, laboratory tests, and other study procedures;
Willing to comply with the arrangement during the study period can not participate in any other clinical research on drugs and medical devices.
