ClinConnect Summary

This clinical trial is looking at a new treatment combination for patients with advanced colorectal cancer that hasn't responded well to standard therapies. The researchers want to see if combining Fruquintinib with two other medications, S-1 and raltitrexed, can improve treatment outcomes for these patients. While Fruquintinib has been used as a third-line treatment, its effectiveness could be enhanced when paired with S-1 and raltitrexed.

To participate in this trial, you need to be at least 18 years old and have been diagnosed with metastatic colorectal cancer. You should have already tried other chemotherapy treatments that didn’t work for you, and your health needs to be stable enough for participation. Participants can expect to receive the new combination of medications and will be monitored closely for safety and effectiveness. This trial is currently recruiting participants, so if you or someone you know fits the criteria, it may be a good opportunity to help advance cancer treatment options.
