NCT01641341

Brief Summary

Overview of Methods: This is a double blind, randomized controlled trial with a non-balanced randomization and a cross-over to active treatment for placebo treated individuals who do not respond to the placebo treatment. Data collected will help determine the feasibility of the study design in primary care offices. Patient outcome data will provide a more precise estimate of power for a larger, classic randomized trial to determine if such a study can be reasonably undertaken within primary care practices. Aims: The aims of this pilot study are to: 1) Evaluate how well Genova Diagnostics (GDx) IBS tests can be integrated into primary care, 2) examine the effects of the Genova Diagnostics (GDx) test on treatment, and 3) observe and track patients' health, quality of life and clinical outcomes related to IBS during the study period.

    20 to 40% of the control/placebo patients and approximately 70-75% of the treatment patients will experience a positive outcome as determined by both the daily log sheets and the modified Rome criteria administered at baseline, 8 and 16 weeks.
