Keverprazan-Minocycline Dual Therapy vs Bismuth Quadruple Therapy for H. pylori Eradication

Official title: Efficacy and Safety of Keverprazan-minocycline Dual Therapy With Different Treatment Durations Versus Bismuth-based Quadruple Therapy for Helicobacter Pylori Eradication: an Open-label, Multicenter, Randomized, Non-inferiority Trial.

Run by Nanjing First Hospital, Nanjing Medical University · NCT07904429 · Data updated 2026-11-12

This trial tests whether a keverprazan-minocycline dual therapy can eradicate Helicobacter pylori as well as or better than a bismuth-based quadruple therapy in adults who haven’t had eradication treatment before.

Is this trial a fit for you?

Likely a good fit

Adults aged 18–65 with confirmed H. pylori infection who have not received prior eradication therapy and can provide informed consent.

Probably not a fit

Patients with allergies to study drugs, active peptic ulcer disease, or significant comorbidities may not benefit and could be excluded for safety reasons.

What this trial studies

This randomized phase 3 trial compares two regimens for Helicobacter pylori infection. Participants aged 18 to 65 with confirmed infection and no prior eradication therapy will receive either a keverprazan-minocycline dual therapy or a bismuth-based quadruple regimen. The study will evaluate eradication rates, patient adherence, and adverse drug reactions to determine relative safety and effectiveness. Primary outcomes focus on eradication success, while safety and tolerability are also closely monitored. Conducted at Nanjing First Hospital, the trial aims to inform optimal first-line treatment options for H. pylori.

Why it matters

Potential benefit: If successful, patients may achieve higher or comparable eradication rates with a simpler regimen and potentially fewer adverse effects.

How similar studies have gone: Previous studies have explored multi-drug regimens for H. pylori; this direct comparison of a dual therapy versus a bismuth-based regimen represents a novel approach within Phase 3.
