Abstract

Background: Vonoprazan (VPZ)-based triple therapy has been reported to have greater efficacy than a proton pump inhibitor (PPI)-based triple therapy for Helicobacter pylori (H. pylori) eradication. However, because VPZ is more expensive than PPIs such as rabeprazole (RPZ), economic evaluation is essential.

Methods: We performed a retrospective study on 209 patients who underwent first-line eradication of H. pylori infection in Fuyoukai Murakami Hospital from 1 March 2015 to 31 March 2016. Patients who received VPZ, amoxicillin (AMPC) and clarithromycin (CAM) were assigned to the VPZ/AC group (n = 111) and patients who received RPZ, AMPC and CAM to the RPZ/AC group (n = 98). We compared the patients’ backgrounds, including age, gender, use of high-dose CAM, past history of peptic ulcer, smoking and drug-related adverse events between the two groups. We defined cost as direct medical costs per patient and effectiveness as the first-line eradication rate in the intention-to-treat (ITT) analysis and analyzed the cost-effectiveness using the cost-effectiveness ratio (CER) and incremental cost-effectiveness ratio (ICER).

Results: There was no significant difference in the patients’ backgrounds. The ITT analysis revealed an eradication rate of 94.6% for VPZ/AC and 86.7% for RPZ/AC. VPZ/AC cost 1155.4 Japanese yen (JPY) higher than RPZ/AC (34063.4 vs. 32908.0, JPY). CER of VPZ/AC was less than that of RPZ/AC (360.1 vs. 379.4, JPY per percent) and ICER of VPZ/AC was 147.0 JPY (1.28 Euro (EUR), 1 EUR =115 JPY) per percent.

Conclusions: VPZ/AC was more cost-effective than RPZ/AC as first-line therapy for H. pylori eradication.
