ClinConnect Summary

This clinical trial is investigating the combination of two medications, regorafenib and raltitrexed, as a potential treatment option for patients with advanced colorectal cancer who have not responded to previous treatments. The goal is to see how effective and safe this combination is for patients who have already tried other therapies. The study will take place at multiple locations and is currently not recruiting participants.

To be eligible for this trial, participants must be at least 18 years old and have a confirmed diagnosis of metastatic colorectal adenocarcinoma, meaning the cancer has spread beyond its original site. They should have experienced disease progression after receiving two prior treatments. Participants will also need to meet specific health criteria, such as having a certain level of liver function and a life expectancy of at least three months. Those who join the trial can expect close monitoring by the research team to assess their health and how well the treatment works. It's important to note that there are several health conditions that may exclude someone from participating, so potential participants should discuss their health history with their doctor.
