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

NCT05771181 | Recruiting Phase 2

• 1 other identifier: VENTIF
• Study Type: interventional
• Target: 25
• Locations: 1 country
• Sites: 1

Brief Summary

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.

• Patients with ECOG score of 0-1 and expected survival time ≥3 months, patients who can cooperate to observe adverse reactions and efficacy;
• At least one measurable tumor lesion according to RECIST 1.1 criteria;
• Good organ function:
• neutrophil ≥1.5\*109/L; Platelet ≥100\*109/L; Hemoglobin ≥9g/dl; Serum albumin ≥3g/dl;
• Thyroid stimulating hormone (TSH) ≤ 1 times the upper limit of normal, T3 and T4 in the normal range;
• bilirubin ≤ 1.5 times the upper limit of normal value; ALT and AST≤ 2 times the upper limit of normal;
• 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;

You may not qualify if:

• Pathological diagnosis of other intestinal tumors, such as gastrointestinal stromal tumor;
• Tumor tissues were dMMR detected by immunohistochemistry, or MSI-H detected by PCR or NGS
• Prior treatment with PD-1 antibody, PD-L1 antibody, or CTLA-4 antibody;
• Previous or concurrent history of other malignant tumors, excluding adequately treated non-melanoma skin cancer, cervical carcinoma in situ and thyroid papillary carcinoma;
• Active autoimmune disease, history of autoimmune disease (such as interstitial pneumonia, colitis, hepatitis, hypophysitis, vasculitis, nephritis, hyperthyroidism, hypothyroidism, including but not limited to these diseases or syndromes); It does not include autoimmune-mediated hypothyroidism treated with stable doses of thyroid replacement hormone; Type I diabetes on stable doses of insulin; Vitiligo or cured childhood asthma/allergy without any intervention in adulthood;
• A history of immunodeficiency, including HIV positive, other acquired or congenital immunodeficiency diseases, or organ transplantation or allogeneic bone marrow transplantation;
• Contraindications to antiangiogenic drugs (such as active bleeding, gastrointestinal bleeding, hemoptysis, etc.);
• History of interstitial lung disease (excluding radiation pneumonitis without steroid treatment) and non-infectious pneumonia;
• Patients with active pulmonary tuberculosis infection detected by medical history or CT examination, or with a history of active pulmonary tuberculosis infection within 1 year before enrollment, or with a history of active pulmonary tuberculosis infection more than 1 year before enrollment but without regular treatment;
• The subject has active hepatitis B (HBV DNA ≥2000 IU/mL or 104 copies/mL), hepatitis C (hepatitis C antibody positive and HCV-RNA above the detection limit of the assay)
