Trial of 5-Fluorouracil (5FU)-Based Therapy in Combination With Fruquintinib in Patients With Locally Advanced Unresectable or Metastatic Colorectal Cancer

This Phase II clinical trial at Houston Methodist Neal Cancer Center is evaluating the safety and efficacy of combining 5-Fluorouracil (5FU) -based chemotherapy (either FOLFIRI: folinic acid, 5FU, irinotecan; or mFOLFOX6: folinic acid, 5FU, oxaliplatin) with fruquintinib as a first-line treatment for patients with locally advanced unresectable or metastatic colorectal cancer. Fifty patients will receive treatment in 28-day cycles, with fruquintinib initially dosed at 4 mg daily and potentially increased to 5 mg if no significant toxicities are observed. After six months, patients showing stable disease or better will transition to a maintenance phase with 5FU and fruquintinib, continuing until disease progression or other discontinuation criteria are met. The primary endpoint is time to progression based on RECIST v1.1 criteria, while secondary endpoints include safety, tolerability, and duration of response. The trial is being conducted across multiple Houston Methodist hospitals and is currently the only first-line CRC trial available in the system. If successful, it could offer a new therapeutic option and inform future treatment guidelines for advanced colorectal cancer.
