Endpoint Determination Study for An Antibody Guided Dietary Restriction Trial Using Biomerica InFoods® IBS Test in Patients With a Previous Diagnosis of Irritable Bowel Syndrome (IBS)

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.
