Clinical Trial Summary

The objective of this clinical trial is to evaluate the efficacy and safety of combining fruquintinib with hepatic artery infusion (HAI)-FOLFOX in the treatment of refractory colorectal cancer with liver metastasis.

Description:

Colorectal cancer (CRC) is the third most common cancer globally, accounting for approximately 10% of all cancer cases, and is the second leading cause of cancer-related deaths worldwide. Significant advancements have been made in treating metastatic colorectal cancer (mCRC) over the past two decades, primarily due to continuous improvements in first-line treatment regimens. However, treatment options are relatively limited for patients with mCRC who do not respond to standard first-line treatments or who develop chemotherapy resistance. Approved second-line treatments include regorafenib, fruquintinib, and TAS-102, but their reported efficacy and overall survival (OS) rates are not ideal. Fruquintinib is a novel small-molecule anticancer drug classified as a quinazoline, acting as a potent and highly selective inhibitor of vascular endothelial growth factor receptor (VEGFR) tyrosine kinase. Preclinical and clinical studies conducted in China and the United States have demonstrated significant anticancer activity of fruquintinib in solid tumors. The prospective randomized controlled clinical study FRESCO-2 showed that fruquintinib significantly improved median OS (7.4 months vs. 4.8 months; P < 0.001) and median progression-free survival (PFS) (3.7 months vs. 1.8 months; P < 0.001) compared to the placebo group. These results are consistent with previous FRESCO study findings. Although these studies provide strong evidence for fruquintinib in treating refractory mCRC patients, the overall improvement in survival is limited, with a 6-month PFS rate of only about 20% (FRESCO: 19.3%, FRESCO-2: 22.7%). Thus, there is a need for new second-line treatment options to further enhance efficacy and survival in refractory mCRC patients. Recent studies have shown that combining fruquintinib with paclitaxel as a second-line therapy demonstrates good efficacy and safety in advanced gastric cancer patients. Additionally, fruquintinib combined with sintilimab has shown some antitumor activity, particularly in mCRC patients with pMMR status. Therefore, combining fruquintinib with other anticancer drugs might offer a new treatment direction for refractory mCRC. Liver metastasis is the most common form of metastasis in colorectal cancer. Normal liver tissue primarily receives blood supply from the portal vein, while colorectal cancer liver metastases mainly receive blood from the hepatic artery. This dual blood supply characteristic has led to the development of hepatic artery infusion (HAI), a treatment method delivering high concentrations of chemotherapy drugs directly to liver metastases, minimizing toxicity to normal liver tissue and surrounding organs. For mCRC patients with chemotherapy resistance and liver-dominant metastasis, treatments such as yttrium-90 resin microsphere selective internal radiation therapy (Y-90 SIRT) are recommended by NCCN guidelines, although Y-90 SIRT is not yet widely available domestically. Fluorouracil (5-FU) and floxuridine (FUDR) are the most commonly used drugs for hepatic artery infusion chemotherapy (HAIC), with high first-pass metabolism rates and short half-lives, suitable for HAI. Studies have reported that HAIC combined with systemic chemotherapy shows high efficacy (76%) and a conversion surgery rate of 47% in mCRC patients who have undergone multiple lines of treatment. Cercek et al. found that mCRC patients resistant to at least three standard systemic treatments (n = 57) benefited from HAI-FUDR, with partial response (PR) and stable disease (SD) rates of 33% and 54%, respectively. However, many countries, including China, no longer produce FUDR injections, necessitating the search for alternative drugs or combinations for HAIC. Compared to systemic oxaliplatin chemotherapy, hepatic artery infusion chemotherapy with oxaliplatin has a high hepatic extraction rate of 0.47 and good safety. A phase II clinical study using oxaliplatin HAIC combined with intravenous 5-FU as first-line treatment showed an objective response rate (ORR) of 64% and a median OS of 27 months in patients with unresectable CRLM. Another study by the same team found that oxaliplatin HAIC had a disease control rate of 87% (n = 39) in CRLM patients who had previously received FOLFIRI or FOLFOX treatments, with 62% achieving partial response, suggesting that oxaliplatin-based HAIC could overcome resistance to previous oxaliplatin-containing systemic therapies. Due to these promising results, several prospective randomized clinical studies are currently underway, such as the phase II SULTAN study investigating oxaliplatin HAIC combined with systemic FOLFIRI as salvage therapy in patients with unresectable localized mCRC after systemic chemotherapy induction. Recent retrospective studies and randomized clinical trials have confirmed that HAI-FOLFOX alone or in combination with other drugs significantly improves the prognosis of patients with advanced hepatocellular carcinoma. Our previous retrospective analysis of 21 patients with recurrent, unresectable CRLM after multiple lines of treatment, who received oxaliplatin + 5-FU (FOLFOX) or FUDR HAIC with or without systemic chemotherapy, showed an ORR of 28.6%, with 7 patients successfully undergoing conversion surgery. The median PFS was 6.3 months, with a 6-month PFS rate of 61.9%. However, due to the limited sample size and retrospective design of our study, caution is needed when generalizing these results. To address the limitations of previous studies and provide more robust evidence, this prospective randomized clinical study will investigate the synergistic effects of combining fruquintinib with HAI-FOLFOX. The aim is to determine whether this combination improves the efficacy in CRLM patients who have progressed after standard systemic chemotherapy compared to fruquintinib monotherapy. By systematically observing a larger patient sample, we hope to understand the potential advantages of this treatment regimen in improving PFS, ORR, and OS. This prospective study will provide valuable insights into the potential clinical benefits of fruquintinib combined with HAI-FOLFOX, paving the way for new treatment strategies and advancing personalized treatment for patients with refractory metastatic colorectal cancer.
