Trial Outcomes & Findings for Safety, Tolerability, and Biosignature of Humanized Prebiotics in Healthy Adults (NCT NCT06068894)
NCT ID: NCT06068894
Last Updated: 2026-02-05
Results Overview
The overall Patient-Reported Outcomes Measurement Information System (PROMIS) score symptom (composite) was calculated as follows: Individual items from the GI questionnaire were grouped into seven symptom domains: abdominal pain, bloating, abdominal distension, flatulence, constipation, diarrhea, and nausea. Each item was rated on a 0-4 scale (0 = "never," 4 = "always"). For each participant at each visit (week 0 and week 4), a domain-specific symptom severity score was defined as the maximum item score within that domain (range 0-4). Using the seven domain severity scores, a composite PROMIS maximum GI measure was calculated for each visit. Composite PROMIS maximum was defined as the maximum severity score cumulatively across all seven domains, representing the participant's worst GI symptoms at that time point. The range of the composite PROMIS maximum score is 0-28 with lower scores representing lowest GI symptoms.

Lactosamine-enriched "Humanized" Galacto-oligosaccharides (hGOS)
The treatment will consist of 10-15 g/day of hGOS, which will be provided to participants as a powder that can be added to any non-alcoholic beverage. The intervention will last for 4 weeks since the research team has shown in adult individuals that a 4-wk period allows for the observation of changes to the gut microbiome. The study will end after the second time-point sample collection at 4 weeks.

Placebo
The placebo comparator treatment will consist of 10-15 g/day placebo powder, that can be added to any non-alcoholic beverage. The intervention will last for 4 weeks to mirror the treatment arms. The study will end after the second time-point sample collection at 4 weeks.
Matching Placebo: 10-15 g/day powdered corn syrup comprised of fructose, glucose, and an inert cellulose material that matches the consistency, color sweetness, and taste of the prebiotics, that can be added to any non-alcoholic beverage.

The treatment will consist of 10-15 g/day of GOS, which will be provided to participants as a powder that can be added to any non-alcoholic beverage. The intervention will last for 4 weeks since the research team has shown in adult individuals that a 4-wk period allows for the observation of changes to the gut microbiome. The study will end after the second time-point sample collection at 4 weeks.

Placebo
n=11 Participants
The placebo comparator treatment will consist of 10-15 g/day placebo powder, that can be added to any non-alcoholic beverage. The intervention will last for 4 weeks to mirror the treatment arms. The study will end after the second time-point sample collection at 4 weeks.
Matching Placebo: 10-15 g/day powdered corn syrup comprised of fructose, glucose, and an inert cellulose material that matches the consistency, color sweetness, and taste of the prebiotics, that can be added to any non-alcoholic beverage.
