Tegoprazan-Based Therapies for H. Pylori Eradication: A Randomized Controlled Trial

Sponsor: Zhongshan Hospital (Xiamen), Fudan University

Summary

Current first-line Helicobacter pylori eradication protocols involve multidrug regimens comprising a proton pump inhibitor (PPI) or bismuth agent combined with dual antibiotics (e.g., clarithromycin, amoxicillin, quinolones, furazolidone, nitroimidazoles, or tetracycline) administered for 7-14 days. In China, the bismuth-containing quadruple therapy (BQT) remains the standard first-line treatment for H. pylori infection. However, BQT implementation is challenged by polypharmacy burdens, substantial adverse events, and suboptimal treatment adherence. Emerging evidence suggests that simplified dual therapies pairing acid suppressants (PPIs or potassium-competitive acid blockers \[P-CABs\]) with high-dose amoxicillin achieve comparable eradication rates to BQT while demonstrating superior tolerability and adherence profiles. Notably, the comparative efficacy of tetracycline-based versus amoxicillin-based dual regimens remains unexamined in controlled clinical trials. Our preliminary investigations established that optimized PPI-amoxicillin dual therapy achieves \>90% eradication rates in treatment-naïve populations. Building on these findings, this prospective randomized controlled trial will comparatively assess the effectiveness of tegoprazan-a novel P-CAB exhibiting potent acid inhibition-when co-administered with either amoxicillin or tetracycline in H. pylori-positive adults. The investigation aims to establish an evidence framework for streamlining eradication protocols through pharmacodynamic optimization while mitigating antimicrobial resistance development.
