Irritable bowel syndrome (IBS) is a common functional bowel disorder that imposes a considerable burden on health-related quality of life (QOL) worldwide. Irritable Bowel Syndrome (IBS) is a common digestive disorder affecting 7-21% of the general population. IBS with predominant constipation (IBS-C) is a subtype of IBS that accounts for more than a third of the IBS diagnosed.
The study Sponsor, Devintec SAGL, presents GA-AT0119, which acts by forming a mechanical barrier on the intestinal mucosa thanks to xyloglucan and pea proteins avoiding the increased intestinal permeability, bacterial invasion to intestinal tissues, and subsequent intestinal inflammation. The formulation of GA-AT0119 is completed with chia seed powder which provides a laxative effect by retaining water in the intestine increasing stool bulk and accelerating fecal transit.
There is increasing evidence that the pathophysiology of IBS is multifaceted involving mucosal inflammation, visceral hypersensitivity, microbial dysbiosis, dietary factors, and altered intestinal permeability (IP). Several studies have shown increased intestinal permeability in patients with irritable bowel syndrome. Serum zonulin, a biomarker of impaired increased permeability, is increased in patients' constipation-predominant irritable bowel syndrome compared to a healthy population and the levels are comparable to celiac disease.
Each subject will be asked to sign the Informed Consent Form (ICF). The patients diagnosed with IBS-C will be randomized in 1:1 ratio. The treatment will be administrated according to the approved leaflet and study procedures. Eligible patients will be randomized to receive either GA-AT0119 or Placebo. Patients will be treated according to the approved leaflet. The study subjects will return at day 7, 15 and day 28 for evaluation. Each subject will undergo a washout period of 28 days. At Day 56 each subject will be evaluated and will receive the crossover therapy line and start administration. Subject will be evaluated at Day 84 at the end of the crossover period. Patients will be evaluated for constipation symptoms, global assessment for tolerability, safety. Each subject will receive a diary where bowel frequency, type and transit time will be completed during product administration. From visit 2 to visit 6, patients will be evaluated for treatment adherence and clinical symptoms recurrences. Each subject will complete 2 additional phone follow-ups Visit for safety reporting and clinical symptoms recurrences according to protocol. During the follow-up visits subject will be evaluated also by using Likert scale for Abdominal Pain and discomfort, Sickness Impact Profile score, IBS-VAS scale and IBS-QoL.

| Measure | Description | Time Frame |
|---|---|---|
| Change from baseline in Subjective Symptom Improvement assessed through Likert scale (Discomfort, Bloating Abdominal Pain) at day 7, 15, 28, 56, 84,114,144 | The clinical symptoms that are going to be assessed through the 7 point Likert Scale are: Bloating, Discomfort, abdominal pain. Likert scale - level of acceptability:
| 144 days |
| Change from baseline in BMI assessed at Day 7,15, 28, 56,84 | The BMI will be evaluated | 84 days |
| Change from baseline in stool consistency will be assessed at Day 0, 7, 15, 28, 56, 84, 114, 144, through the Bristol Stool Scale. | Type of stool will be assessed according to the Bristol Stool Chart ((Stool Type 1 - severe constipation, Stool Type 2 - mild constipation, Stool Type 3 - normal, Stool Type 4 - normal, Stool Type 5 - lacking fiber, Stool Type 6 - mild diarrhea, Stool Type 6 - severe diarrhea) | 144 days |
| Change from baseline score in IBS-QoL questionnaire (Information Sheet on the Irritable Bowel Syndrome - Quality of Life Measure) at Day 7, 15, Day 28 and Day 56, Day 84, Day 114, Day 144 | Patients will respond to the IBS-QoL questionnaire. The individual responses to the 34 items are summed and averaged for a total score and then transformed to a 0-100 scale for ease of interpretation with higher scores indicating better IBS specific quality of life. | 144 days |
| Change of Sickness Impact Profile score from Baseline to Day 28 and day 56, day 84, Day 114, Day 144 | The generic health status, the physical, mental and social aspects of health-related functioning and behavior aspectes will be measred through - The Sickness Impact Profile (All the items are scored dichotomously (no=0, yes=1); The items reported as "yes" are used to calculate the scores; higher scores indicate more health-related behavioral problems) |
