Is this trial a fit for you?

Likely a good fit

Adults aged 18 or older with dyspepsia and histologically confirmed H. pylori–positive gastritis who can provide informed consent are eligible.

Probably not a fit

Patients with peptic ulcer disease, prior gastric surgery, current or prior malignancy, severe unstable comorbidities, known hypersensitivity to product ingredients, or other exclusionary conditions are unlikely to be eligible or to benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Eighty adults with dyspepsia and histologically confirmed H. pylori gastritis will be randomized 1:1 to receive either 30 ml daily of the oral supplement Carminal plus standard H. pylori therapy or placebo plus standard therapy. Treatment is started after diagnostic upper endoscopy with biopsy and continued for 12 weeks after confirmed H. pylori eradication, with the full study lasting about 24 weeks. The primary outcome is mucosal healing assessed by follow-up endoscopy and histology performed after the treatment period. The trial is interventional, phase 2, and designed to detect whether adding this antioxidant Aloe vera–based supplement improves gastric mucosal recovery beyond standard eradication therapy.

Why it matters

Potential benefit: If successful, Carminal could speed mucosal recovery and reduce gastric inflammation after H. pylori eradication, potentially lowering longer-term gastric complications.

How similar studies have gone: Clinical evidence for Aloe vera or similar antioxidant supplements in improving H. pylori–related mucosal healing is limited and mixed, so this approach is relatively novel and not yet well established.
