Study Summary

This trial is testing whether a high dietary fiber formula can reduce chemotherapy-induced diarrhea in patients with metastatic colon cancer.

Who is the study for?
This trial is for adults with metastatic colon cancer who are set to receive irinotecan-based chemotherapy. They must have a good performance status, meaning they're able to carry out daily activities with little or no assistance. Their blood counts and organ functions need to meet specific criteria, and they shouldn't have had irinotecan or severe diarrhea recently.Check my eligibility
What is being tested?
The trial is testing NBT-NM108, a high dietary fiber formula designed to reduce chemotherapy-induced diarrhea by supporting gut bacteria health. It aims to improve patients' tolerance of the chemo drug irinotecan, which often causes diarrhea in those treated for advanced colon cancer.See study design
What are the potential side effects?
While the side effects of NBT-NM108 aren't detailed here, it's generally expected that high fiber supplements could cause bloating, gas or changes in bowel habits as your body adjusts. The main focus is on reducing severe side effects from chemotherapy.
