BACKGROUND: The potassium-competitive acid blocker vonoprazan (VPZ) has potent
acid-inhibitory effects and may offer clinical advantages over conventional
therapy for acid-related disorders. AIM: To investigate the efficacy and safety
of VPZ in patients with erosive oesophagitis (EO). METHODS: In this multicentre,
randomised, double-blind, parallel-group, dose-ranging study, patients ?20 years
with endoscopically confirmed EO [Los Angeles (LA) grades A-D] received VPZ 5,
10, 20 or 40 mg, or lansoprazole (LPZ) 30 mg once daily for 8 weeks. The primary
endpoint was the proportion of healed EO subjects as shown by endoscopy at week
4. RESULTS: A total of 732 subjects received VPZ or LPZ. The proportion of healed
EO subjects at week 4 was 92.3%, 92.5%, 94.4%, 97.0% and 93.2%, respectively,
with VPZ 5, 10, 20 and 40 mg and LPZ 30 mg. All VPZ doses were non-inferior to
LPZ when adjusted for baseline LA grades A/B and C/D. Among those with LA grades
C/D, the proportions of healed EO subjects were 87.3%, 86.4%, 100%, 96.0% and
87.0%, respectively, with VPZ 5, 10, 20 and 40 mg and LPZ 30 mg. The incidence of
adverse events was similar across the groups. CONCLUSIONS: Vonoprazan was
effective and non-inferior to LPZ in healing EO. VPZ 20 mg or higher was highly
efficacious for severe EO (LA grades C/D). VPZ was associated with no safety
concern during this 8-week study, while there was a dose-dependent increase in
serum gastrin. Once-daily VPZ 20 mg is the recommended clinical dose for treating
EO.
