Study Summary

This trial is testing whether a different drug given with 5-FU will help people with metastatic colorectal cancer live longer without their disease getting worse.

Who is the study for?
This trial is for adults over 18 with metastatic colorectal cancer that can't be removed by surgery. They must have measurable disease, no prior systemic chemotherapy for advanced disease, and a life expectancy of at least 3 months. Pregnant or breastfeeding women, those not using contraception if of child-bearing potential, and individuals with certain health conditions like uncontrolled heart disease or inadequate organ function are excluded.Check my eligibility
What is being tested?
The study compares two treatments to see which one keeps the cancer from getting worse longer. One group receives a combination of the drugs CoFactor and Avastin along with the chemotherapy drug 5-FU; another group gets Leucovorin (LV) instead of CoFactor with Avastin and 5-FU.See study design
What are the potential side effects?
Possible side effects include reactions to medication infusions, increased risk of bleeding or blood clots due to Avastin, diarrhea from 5-FU, fatigue, lowered immunity leading to infections, liver issues from elevated enzymes levels in blood tests.
