Comparative Efficacy of Tegoprazan vs Esomeprazole/Sodium Bicarbonate for the Treatment of Helicobacter pylori Infection.

Potassium-competitive acid blockers and proton pump inhibitors/sodium bicarbonate can rapidly increase intragastric pH. In this study, we aimed to compare the clinical outcomes of tegoprazan-based and esomeprazole/sodium bicarbonate-based triple therapies in the treatment of Helicobacter pylori infection. We retrospectively reviewed the data of patients with H. pylori infection treated with a 14-day tegoprazan-based triple therapy or 14-day esomeprazole/sodium bicarbonate-based triple therapy. The primary end point was the H. pylori eradication rate with first-line treatment in an intention-to-treat analysis. Secondary end points included the eradication rate with first-line therapy in the per-protocol analysis and adverse events associated with eradication therapy. Of the 854 included patients, 435 were treated with tegoprazan-based therapy, and 419 received esomeprazole/sodium bicarbonate-based therapy. In the intention-to-treat population, no significant difference in eradication rate was detected between the tegoprazan-treated and esomeprazole/sodium bicarbonate-treated groups (78.6% [95% confidence interval (CI), 74.6-82.3%] vs 81.4% [95% CI, 77.4-84.9%], P = 0.313). The per-protocol analysis also revealed a similar eradication rate between groups (tegoprazan vs esomeprazole/sodium bicarbonate: 85.5% [95% CI, 81.8-87.5%] vs 87.8% [95% CI, 84.1-90.7%], P = 0.339). However, abdominal discomfort and diarrhea were more common in the esomeprazole/sodium bicarbonate-treated group than in the tegoprazan-treated group (abdominal discomfort: 1.1% vs 3.8%, P = 0.012; diarrhea: 9.9% vs 21.2%, P < 0.001). The efficacy of the esomeprazole/sodium bicarbonate-based triple therapy for H. pylori eradication was comparable with that of the tegoprazan-based triple therapy. However, esomeprazole/sodium bicarbonate-based therapy exhibited a higher risk of abdominal discomfort and diarrhea than tegoprazan-based therapy.
