Plain English Summary
Background and study aims
Gastroesophageal reflux (English acronym GERD, Gastro-Oesophageal Reflux Disease) is caused by a functional defect in the oesophagus and is characterized by the reflux of stomach contents and of gases produced in the intestine into the oesophagus, generating a reflux of acid material. The GERD symptoms include burning chest, acid and alkaline regurgitation from lying down, stomach cramps, and difficulty in swallowing. Some people have gastric reflux which is not cured by other drugs. In this study we evaluate if GERDOFF tablets can be helpful to reduce gastric reflux and heartburn.
Who can participate?
Adults aged 18 and older who have gastric reflux.
What does the study involve?
All participants receive GERDOFF tablets for two weeks after meals and before bedtime. Participants are followed up to see if they
What are the possible benefits and risks of participating?
The possible benefits are symptoms alleviation and improvement of quality of life; the main potential risk is that the device does not work. Side effects to treatement are not expected since the product is already commercially available.
Where is the study run from?
The University of Modena (Italy) and the Hospital of Cernusco sul Naviglio (Italy) are the centres taking part in this trial. The University of Modena is the lead centre.
When is study starting and how long is it expected to run for?
The study started in 2014 and is currently completed.
How long will the trial be recruiting participants for?
SOFAR Spa (Italy)

Exploratory, post-market, open-label clinical investigation to evaluate the effect of the medical device, GERDOFF® melt-in-mouth tablets, in patients with GERD and with reduced effect or ineffectiveness of alginates treatment.
GERDOFF® efficacy in patients with GERD
The purpose of this exploratory clinical investigation is to evaluate the effect of GERDOFF® in reducing the number of 'heartburn' episodes, GERD symptom manifestation, per week, after 14 days of treatment, by assessing the number of days with the symptom "heartburn" over the last week of treatment compared to baseline.

All patients are trained to take 4 melt-in -mouth tablets containing high molecular weight hyaluronic acid, aluminum hydroxide, and chondroitin sulphate (GERDOFF® 1100 mg; SOFAR S.p.A., Trezzano Rosa, Milan, Italy) after meals and before bedtime, for 14 days.
Participants are followed up to see if there is a reduction in the number of heartburn episodes per week and the frequency of their symptoms.
Primary outcome measure
Reduction in the number of heartburn episodes per week is measured using patient diaries at baseline, day 7 and day 14.
Secondary outcome measures
1. Frequency of GERD- related symptoms are measured using patient diaries and the GIS Gerd impact scale questionnaire at baseline, day 7 and 14
2. Patient satisfaction is measured using GIS Gerd impact scale questionnaire at baseline, day 7 and day 14
3. Number of days without symptoms are measured using patient diaries at baseline, day 7 and day 14
4. Patient’s compliance to the therapy is measured using patient diaries at baseline, day 7 and day 14
