Microbiotic Product to Promote Microbiome Health and Improve Chemotherapy Delivery

Официальное название

A Randomized Trial of Microbiotic Product (NBT-NM108) to Promote Microbiome Health and Improve Chemotherapy Delivery

Обзор

This phase II trial tests whether NBT-NM108 works in reducing chemotherapy-induced diarrhea in patients with colon cancer that has spread to other places in the body (metastatic). Irinotecan is one of the most used medicine for colon cancer, but it leads to diarrhea in most patients receiving it and among some of them, severe diarrhea can occur. NBT-NM108 is a high dietary fiber formula that is developed based on research findings that have shown that high fiber diets can help maintain healthy bacteria in the gut and improve gut function. Giving NBT-NM108 to patients with colon cancer receiving chemotherapy may help relieve or lessen diarrhea symptoms and lead to improved tolerance of the chemotherapy drug, irinotecan.

Подробное описание

PRIMARY ENDPOINT:

Dose Intensity of Irinotecan administered (mg/m2/week)

SECONDARY ENDPOINTS:

1. Reduction in % Patients Needing Dose Modification for Diarrhea 2. Toxicity Grade of diarrhea 3. Response Rate 4. Time to Progression-free survival

EXPLORATORY ENDPOINTS:

1. 16S rRNA gene sequencing to reveal changes of the gut microbiota including institution of foundation guilds and restoration of healthy microbiome 2. Short chain fatty acids analysis (promotion of acetic and butyric acid production) 3. Markers for gut inflammation such as fecal lipocalin 2 4. Gut barrier function test to see if the restoration of healthier gut microbiota would improve gut barrier function.

Вмешательства

  Patients receive irinotecan-based chemotherapy per standard of care.

Первичные конечные точки

• The number of participants with treatment-related Adverse Events as Assessed by Cancer Therapy Evaluation Program Common Toxicity Criteria (CTCAE) Version 5.0 for toxicity and Adverse Event reporting [Срок оценки: Eight weeks]

Критерии участия

Критерии включения

• 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

Критерии исключения

• 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.
