About this study
Official title: Phase II Clinical Study of Vitamin E Combined With Fruquintinib and Tislelizumab in Patients With Microsatellite Stabilized Metastatic Colorectal Cancer Who Failed Standard Therapy
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.
Read the detailed description
Dietary supplements are commonly used during conventional cancer treatment. Vitamin E has a variety of functions, including enhancing immunity, anti-inflammation, and anti-oxidation. Tislelizumab is an anti-PD-1 monoclonal antibody, and furoquininib is a tyrosine kinase inhibitor that inhibits tumor angiogenesis. Studies have shown that immunotherapy combined with furoquininib has initial efficacy in the treatment of colorectal cancer. Whether vitamin E combined with immunotherapy and furoquininib can improve the prognosis of patients with colorectal cancer deserves to be studied. Therefore, the objective of this study is to evaluate the efficacy and safety of Vitamin E in combination with Fuquinitinib and Tirelizumab in patients with microsatellite stabilized mCRC who have failed standard therapy.

The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 19 inclusion and 14 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 12 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?

How can a doctor refer a patient or contact the research team?
Contact Dawei Li, PhD (+8613774201693, li_dawei@fudan.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
objective response rate (ORR) (time frame: 2 year). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 12 Jun 2025.
