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.

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.
