Clinical Trial Summary

Gastroesophageal reflux disease (GERD), according to the Montreal classification, is defined as a condition that develops when the reflux of stomach contents causes troublesome symptoms and/or complications. GERD, as clinically defined by the presence of heartburn, acid regurgitation, or both, at least once a week, is a global disease, being one of the most common gastroenterological disorders worldwide that affects roughly 10-30% of the general population in the Western world and less than 10% of the Asian populations. GERD complications may be life threatening and range from reflux esophagitis to Barrett's oesophagus and, eventually, adenocarcinoma.

Zinc L-carnosine (brand name in Italy: Hepilor®) is a chelate compound of zinc and L-carnosine, with a long history of more than 20 years of clinical use in Japan that has recently become available in Italy for the treatment of any condition that requires a mucosal protection and mucosal repair within the gastrointestinal tract, thus including GERD. However, clinical data in western countries are limited. The aim of this double-blind, placebo-controlled study is to demonstrate the efficacy of Zinc-l-carnosine in maintaining GERD clinical remission during a 12-week treatment.

Clinical Trial Description

The investigators hypothesise that Zinc-l-carnosine is able to maintain GERD remission, thus improving the quality of life of these patients. A comparison with a placebo is necessary, as GERD symptoms may be heavily influenced by the nocebo/placebo effect.

This is a post-marketing, single center, double-blind, and randomized, placebo-controlled, parallel study. Patients with GERD treated with an 8-week cours of proton pump inhibitors will be randomize and receive either Zinc-l-carnosine or placebo for 12-week. GERD symptoms will be assessed with a questionnaire (modified GERD questionnaire by Locke) monthly for 12 weeks and after a 4-week wash-out. Also, quality of life will be assessed at baseline and at 12 weeks with the 36-item short form survey (SF-36). ;
