Endpoint Determination Study Protocol

Biomerica556 enrolled

Overview

This study is designed to evaluate the most applicable endpoints for evaluation of the Biomerica InFoods® IBS product.

The objective of this Endpoint Determination Study is to address key elements regarding a proposed larger clinical study design: 1. Comparing different potential primary outcome measures 2. Demonstrating that an exclusionary diet as determined by elevated IgG levels using the Biomerica InFoods® IBS Test is associated with alleviation of IBS symptoms 3. Demonstrating the ability to mask the sham diet 4. Demonstrating the safety of the exclusionary diet Subjects' diets will be based on the results of the Biomerica, InFoods® IBS Test. Immunoglobulin G (IgG) levels above a certain threshold are considered a positive response against a specific food or foods. It is expected that severity of symptoms of IBS will decrease when foods that generate a positive immune response in the Biomerica InFoods® IBS test are eliminated from the diet of the IBS patient. The Endpoint Determination Study format will be a double-blinded randomized controlled clinical study enrolling subjects at two trial sites within the United States and designed to evaluate the use of IgG antibody guided dietary restrictions, based on the Biomerica InFoods® IBS Test, in the management of patients diagnosed with Irritable Bowel Syndrome (IBS). The 2 sites will enroll approximately equal numbers of subjects. The target for each site is a minimum of 30 subjects in each classification: IBS with diarrhea \[IBS-D\], IBS with constipation \[IBS-C\] and IBS mixed \[IBS-M\] for a minimum of 90 patients per site, 180 total subjects for this study.

Outcomes

Primary Outcomes

Change in the IBS-API - Abdominal Pain Intensity. The IBS-API is being assessed daily from enrollment (baseline) to study completion; total 10 weeks

Abdominal pain intensity will be measured daily using an 11-point (0-10) numeric rating scale (NRS) that asks subjects to rate their worst abdominal pain over the past 24-hours.

Time frame: Daily for 10 weeks
