Fructan Intolerance

Brief summary

SSDXA-14 is a Phase 2 (feasibility/pilot) double-blind, placebo-controlled, crossover study to evaluate the efficacy and safety of sacrosidase and placebo in 25 subjects objectively diagnosed with fructan intolerance.

Detailed description

This Phase 2 study will evaluate the efficacy and safety of sacrosidase and placebo in male and female subjects aged 18 years or older objectively diagnosed with fructan intolerance via fructan breath test within 6 months prior to informed consent and are negative for inflammatory bowel disease or low-grade GI bacterial infection, detected by fecal calprotectin test, celiac disease, detected by serology for anti-gluten protein antibodies, congenital sucrase-isomaltase deficiency (CSID), detected by sucrose hydrogen-methane breath test, and have a negative result for abnormal uncontrolled thyroid function, detected by the standard TSH blood test. This study will consist of a Screening Visit, Baseline Period, Treatment Period 1, Washout Period, and Treatment Period 2. Subjects will be required to attend 5 clinic visits during study participation. Subjects will be randomized in a 1:1 fashion to either receive sacrosidase or placebo during Treatment Period 1. Following a 7-day Washout Period, subjects will receive their crossover study medication for Treatment Period 2. Subjects will take their assigned study medication for 7 days during each Treatment Period.

Design outcomes

Primary

MeasureTime frameDescription
Change From Baseline in Mean (SD) Total Symptom Score (TSS) at 1 WeekBaseline and 1 weekThe numeric value of the Total Symptom Score (TSS) is derived from the Daily Symptom Questionnaire (DSQ). The DSQ consisted of rating the frequency in the last 24 hours and the severity of 7 symptoms, abdominal bloating, abdominal pain, abdominal cramps, abdominal gas/flatulence, constipation, nausea, and diarrhea. The daily symptom score is calculated by summing the frequency and severity scores for each symptom with a minimum daily score of 0 and a maximum daily score of 98. The TSS is calculated by averaging the combined daily symptom scores during a 7-day period for baseline and 1-week post-intervention during each treatment period and ranges from 0-98, with higher values representing a worse outcome.

Secondary

MeasureTime frameDescription
Change From Baseline in Mean (SD) Frequency Score for Abdominal Bloating From Baseline to 1 WeekBaseline and 1 weekThe Daily Symptom Questionnaire (DSQ) consisted of rating the frequency in the last 24 hours and the severity of 7 symptoms, abdominal bloating, abdominal pain, abdominal cramps, abdominal gas/flatulence, constipation, nausea, and diarrhea. The frequency score for abdominal bloating experienced is calculated by averaging the combined daily scores during a 7-day period for baseline and 1-week post-intervention during each treatment period and ranges from 0-5, with higher values representing a worse outcome.
