Tegoprazan-Amoxicillin Dual Therapy vs. Bismuth Quadruple Therapy for H. Pylori Infection (TATH-1)

RandomizedParallel-groupOpen-labelTreatment

Summary

Standard eradication therapies using proton pump inhibitors (PPIs) require double doses to achieve sufficient acid suppression, yet failure rates remain high due to antibiotic resistance. Tegoprazan, a P-CAB agent, inhibits gastric acid more effectively than PPIs. This study hypothesizes that Tegoprazan-based dual therapy can achieve superior or non-inferior eradication rates compared to standard quadruple therapy. The study evaluates the antibacterial effect of Tegoprazan combined with high-dose Amoxicillin in H. pylori-infected patients.
