Comparison of the Efficacy of Tegoprazan-containing Versus Esomeprazole-containing Dual Therapy for Helicobacter Pylori Eradication: a Prospective, Multicenter, Randomized Controlled Study （SHARE2301）

In 1989, it was suggested that amoxicillin combined with PPI could eradicate Hp infection, and in 2015, a prospective, multicenter, randomized controlled study in Taiwan with a large sample showed that the eradication rate of Hp could reach 96.6% with dual therapy for primary treatment of Hp infection, and the results of intention-to-treat analysis were as high as 95.3%. 95.3%. In 2020, a meta-analysis showed that high-dose dual therapy had the same efficacy and fewer side effects than other recommended regimens in first-line treatment. In terms of dosing days, multiple randomized controlled studies and meta-analyses from 2020-2021 have shown that 14 days of high-dose dual therapy is more effective in eradicating H. pylori.

Tegoprazan, a Potassium-Competitive Acid Blockers (P-CAB), is a new type of acid-suppressing drug that compensates for the short half-life of acid-activated traditional acid-suppressing PPI and the low mucosal healing rate due to insufficient acid suppression. The efficacy of P-CAB agents represented by vonoprazan in H. pylori eradication therapy has been widely verified. 2022, tegoprazan was approved by the State Drug Administration for the new indication of eradication of H. pylori infection in adults in combination with appropriate antimicrobial therapy, and its efficacy in clinical application has not yet been verified.
