Study summary

Gastroesophageal reflux disease (GERD) is a common condition that can cause symptoms including heartburn, acid regurgitation, sour taste and other upper gastrointestinal complaints. This prospective, multicenter, randomized, controlled, non-profit clinical trial will evaluate the clinical efficacy and safety of Mirgeal® Gel, a dietary supplement containing sodium alginate and standardized extracts of licorice (Glycyrrhiza glabra) and blueberry (Vaccinium myrtillus), when used as an add-on to esomeprazole in adults with non-erosive gastroesophageal reflux disease (NERD).

A total of 140 participants will be randomly assigned in a 1:1 ratio to receive either esomeprazole 20 mg/day plus Mirgeal® Gel, 2 sticks per day (1 after lunch and 1 after dinner), or esomeprazole 20 mg/day alone for 4 continuous weeks. Clinical assessments will be performed at baseline and after 2 and 4 weeks of treatment. The study will assess whether adding Mirgeal® Gel to standard proton pump inhibitor therapy improves reflux-related symptoms and quality of life compared with esomeprazole alone.

Read the detailed description

This is a prospective, multicenter, randomized, controlled clinical trial designed to evaluate the safety and clinical efficacy of Mirgeal® Gel as an add-on to proton pump inhibitor therapy in adult patients with non-erosive gastroesophageal reflux disease (NERD). The study is designed to evaluate the superiority in clinical efficacy of the combination of esomeprazole plus Mirgeal® Gel compared with esomeprazole alone.

Mirgeal® Gel (manufacturer: PharmExtracta S.p.A.) is a dietary supplement in stick form containing sodium alginate and standardized derivatives of Glycyrrhiza glabra and Vaccinium myrtillus. Participants will be randomly allocated in a 1:1 ratio to one of two treatment groups. The intervention group will receive esomeprazole 20 mg/day plus Mirgeal® Gel at a dose of 2 sticks per day, with 1 stick taken after lunch and 1 stick after dinner. The control group will receive esomeprazole 20 mg/day alone. Treatment will continue for 4 continuous weeks.

Treatment will begin following the baseline assessment. Clinical visits will be conducted at baseline and after 2 and 4 weeks of treatment. Participants will be monitored throughout the study for clinical outcomes, safety and treatment adherence. The total duration of participation for each subject will be 4 weeks, with no post-treatment follow-up period.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adults aged ≥18 years.
  • Males and females.
  • Diagnosis of non-erosive gastroesophageal reflux disease (NERD), based on the absence of macroscopic lesions of the distal esophageal mucosa on endoscopy performed within 6 months prior to enrollment.
  • Heartburn and/or acid regurgitation at least 3 times per week during the 2 weeks prior to enrollment.
  • Written for study participation obtained prior to the start of the study.

Exclusion criteria

Exclusion Criteria:

  • Active gastric or duodenal ulcer within the previous 3 months.
  • Previous surgery involving the esophagus or treated upper gastrointestinal tract.
  • Absence of erosive esophagitis or Barrett's esophagus.
  • Severe renal or hepatic impairment.
  • Use of proton pump inhibitors (PPIs), H2-antagonists, or systemic within 2 weeks prior to enrollment.
  • Pregnancy.
  • Breastfeeding.
  • Alcohol or drug abuse.
  • to any of the study product components.
  • Participation in another clinical trial within 30 days prior to enrollment.
  • Lack of acceptance of written .
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

What researchers measure

Primary outcomes

  1. Change in GERD-Related Quality of Life Assessed by GERD-HRQL

    Change in gastroesophageal reflux disease symptoms and their impact on quality of life will be assessed using the validated Gastroesophageal Reflux Disease Health-Related Quality of Life (GERD-HRQL) questionnaire. The questionnaire includes 10 items scored from 0 (no problem) to 5 (severe problem), with higher scores indicating greater symptom burden. GERD-HRQL will be administered at baseline, Week 2, and Week 4.

    Time frame: Baseline, Week 2, and Week 4

Secondary outcomes

  1. Change in Reflux Symptoms Assessed by the Reflux Symptom Index (RSI)

    Change in reflux-related symptoms will be assessed using the Reflux Symptom Index (RSI). The RSI evaluates nine reflux-related symptoms, with each item scored from 0 (no problem) to 5 (severe problem). The total score ranges from 0 to 45, with higher scores indicating greater symptom severity.

    Time frame: Baseline, Week 2, and Week 4

  2. Change in Gastroesophageal Reflux Symptom Intensity Assessed by 0-10 Visual Analog Scale

    Change from baseline in the intensity of regurgitation, heartburn, and sour taste in the mouth, assessed using a 0-10 Visual Analog Scale (VAS), where 0 indicates no symptoms and 10 indicates the worst possible symptom. Higher scores indicate greater symptom severity. Assessments will be performed at baseline, Week 2, and Week 4.

    Time frame: Baseline, Week 2, and Week 4

  3. Investigator Global Assessment of Performance (IGAP) Rating of Treatment Effectiveness

    At Week 4, the investigator will assess overall treatment effectiveness using the Investigator Global Assessment of Performance (IGAP), based on the participant's overall clinical evaluation, including patient-reported symptoms, completed questionnaires, and use of rescue medications. Treatment effectiveness will be rated from poor to excellent, with higher ratings indicating better treatment performance.

    Time frame: Week 4

  4. Participant-Rated Palatability of Mirgeal® Gel Using the Study Palatability Questionnaire

    Participants assigned to Mirgeal® Gel will assess the palatability of the study product at Week 4 using the study palatability questionnaire. Participants will provide an overall rating ranging from bad to excellent, with higher ratings indicating better palatability.

    Time frame: Week 4

  5. Incidence of Adverse Events

    Safety and tolerability will be assessed by recording adverse events reported by participants during the study. Adverse events will be documented throughout the treatment period.

    Time frame: From baseline through Week 4

  6. Percentage Treatment Adherence Assessed on a 0-100% Scale

    Treatment adherence will be assessed at Week 4 and reported as a percentage from 0% to 100%, with higher percentages indicating greater adherence to the assigned treatment regimen. Adherence will also be assessed through return of unused Mirgeal® Gel packs or sticks, as applicable.

    Time frame: Week 4
