Fiber fix: new supplement aims to stop Chemo-Induced diarrhea
NCT ID NCT05296681
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a high-fiber product called NBT-NM108 in 42 people with advanced colon cancer who are receiving a chemotherapy drug called irinotecan. The goal is to see if the supplement can reduce or prevent the severe diarrhea that often comes with this treatment. By helping the gut stay healthy, researchers hope patients can better tolerate their chemotherapy and have fewer side effects.

Inclusion Criteria * Biopsy proven and metastatic colon cancer * Candidate for Second-line or later line therapy with irinotecan-based chemotherapy regimen with starting dose of irinotecan at 180 mg/m2 q2w. Participants who have had prior irinotecan will be eligible if they are off irinotecan for at least three months and stools have returned to baseline consistency. * Performance Status (PS) 0-1 * Lab values as acceptable for trials: Absolute Neutrophil Count( ANC) \>1500/uL; Creatinine \< 1.5 x Upper Limit of Normal (ULN); Transaminases \< 5x ULN; Bilirubin \< 1.5 x ULN; Albumin \> 3.0 g/dL * No known UGTA1A\* genotype Exclusion Criteria * Grade two diarrhea or greater (4-6 movements per day over baseline) * Inability to take oral supplements * Current antibiotic therapy * Baseline grade 3-4 diarrhea Participants with grade two diarrhea should undergo stool evaluation with stool test for bacteria (Salmonella, Shigella, Campylobacter, Yersinia Mycobacterium), bacterial toxin (Clostridium difficile), ova and parasites (Giardia, Entamoeba, Isospora, Cyclospora, Cryptosporidium, Microsporidium), or viruses (Cytomegalovirus), associated with an ongoing active infection and diarrhea. They will be eligible if this evaluation shows no infection. * History of the following infections and/or disease which could lead to diarrhea: * History of prior positive gastrointestinal biopsy, gastrointestinal culture, or stool test for bacteria (Salmonella, Shigella, Campylobacter, Yersinia, Mycobacterium), bacterial toxin (Clostridium difficile), ova and parasites (Giardia, Entamoeba, Isospora, Cyclospora, Cryptosporidium, Microsporidium), or viruses (Cytomegalovirus), associated with an ongoing active infection and diarrhea unless fully treated with at least three months normal stool. * History of ulcerative colitis, Crohn's disease, celiac sprue (gluten-enteropathy), chronic pancreatitis, malabsorption, or any other gastrointestinal disease associated with diarrhea.
