Fruquintinib Plus Anti-EGFR Antibody for Third-Line Treatment of RAS Wild-Type mCRC
Part of Cancer, Digestive system clinical trials.
This study aims to evaluate the effectiveness and safety of combining fruquintinib (an oral anti-angiogenesis drug) with cetuximab-beta (an anti-EGFR antibody) in patients with RAS wild-type metastatic colorectal cancer who have already failed at least two lines of standard treatments. Standard therapies for metastatic colorectal cancer often include fluorouracil, oxaliplatin, and irinotecan. However, many patients eventually experience disease progression, and treatment options become limited. Fruquintinib and cetuximab-beta work through different mechanisms: fruquintinib blocks tumor blood vessel growth, while cetuximab-beta blocks EGFR-related cancer cell growth signals. Using these two drugs together may provide additional benefit for patients whose cancer no longer responds to other treatments. This study will enroll 46 patients who meet the eligibility criteria. All participants will take fruquintinib by mouth once daily (3 weeks on and 1 week off) and receive cetuximab-beta by intravenous infusion every 2 weeks. Treatment will continue until the cancer progresses or side effects become intolerable. Doctors will monitor tumor changes every 8 weeks using CT or MRI scans and will also collect blood samples over time to measure circulating tumor DNA (ctDNA), which may help track how the cancer responds to treatment. Safety will be assessed through physical exams, lab tests, and monitoring of side effects. The main goal of the study is to determine the objective response rate (ORR)-how many patients experience measurable tumor shrinkage. Secondary goals include progression-free survival (PFS), disease control rate (DCR), overall survival (OS), and safety outcomes.

Other trials that look related to this one.
This study tests a combination of three drugs—fruquintinib (an anti-angiogenic agent), serplulimab (an immune-boosting antibody), and standard chemotherapy—as a first-line treatment for advanced colorectal cancer with specific genetic mutations. The goal is to see if this combination can help shrink or control tumors better than standard treatment alone.
This study tracks how well fruquintinib works for people with advanced colorectal cancer that has spread. It aims to find factors that predict better outcomes, using blood and tumor samples.
This trial tests a combination of two drugs (5-FU and fruquintinib) in people with advanced colorectal cancer that cannot be removed by surgery or has spread. It is for those who have not had chemotherapy before.
This trial tests a combination of three drugs (fruquintinib, chidamide, and sintilimab) for people with a specific type of metastatic colorectal cancer that has not responded to at least two prior treatments. It aims to see if this combination is safe and effective.
This trial tests a combination of two targeted drugs (cetuximab beta and fruquintinib) with or without an immunotherapy drug for people with a specific type of advanced colorectal cancer that has not been treated before. It aims to see if this approach is safe and effective for those whose tumors have certain genetic markers (RAS and BRAF wild type).
This trial tests two drugs, fruquintinib and raltitrexed, for people with metastatic colorectal cancer that has stopped responding to or is no longer tolerable after standard treatments like fluorouracil, oxaliplatin, and irinotecan. The goal is to see if this combination can help shrink or control the cancer.
