Trial of 5-Fluorouracil (5FU)-Based Therapy in Combination With Fruquintinib in Patients With Locally Advanced Unresectable or Metastatic Colorectal Cancer
Sponsor: The Methodist Hospital Research Institute
Summary
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.

Fruquintinib Combined With Chemotherapy
The intervention in this trial involves administering a combination of 5FU-based chemotherapy and fruquintinib to patients with locally advanced unresectable or metastatic colorectal cancer. Patients receive either the FOLFIRI or mFOLFOX6 regimen, both of which include 5-fluorouracil (5FU), leucovorin (LV), and either irinotecan (FOLFIRI) or oxaliplatin (mFOLFOX6). Fruquintinib is given orally once daily for 21 days in each 28-day cycle. The initial dose of fruquintinib is 4 mg daily for the first three patients to assess safety; if no dose-limiting toxicities are observed, the dose is increased to 5 mg daily for subsequent participants. Treatment continues until disease progression, unacceptable toxicity, or patient withdrawal. After six months, patients with stable disease or better transition to a maintenance phase with 5FU and fruquintinib alone.
