Title: Revaprazan (Revanex(R)), a Novel Acid Pump Antagonist, for Duodenal Ulcer: Results of a Double-Blind, Randomized, Parallel, Multi-Center Phase III Clinical Trial
Abstract: Background/Aims: To assess the comparative efficacy and safety of revaprazan, a novel acid pump antagonist, versus omeprazole in patients with duodenal ulcer, we performed a randomized, double-blind, phase III, multicenter trial. Methods: Two hundred and twenty eight patients were randomized to 4 weeks of treatment with either revaprazan 200 mg or omeprazole 20 mg once daily. Primary efficacy parameter was complete ulcer healing by endoscopy, and secondary parameter was the improvement in the severity of daytime and nighttime pain. Results: Healing rates at 4 weeks (intention-to-treat analysis) were 91.7% with revaprazan 200 mg and 91.3%with omeprazole 20 mg; there were no significant differences between two groups (p=0.9228). In per-protocol analysis, healing rates of revaprazan 200 mg and omeprazole 20 mg were 94.4% and 92.3%, respectively. There was no significant difference in healing rate between two groups (p=0.5666). There was no significant difference between two groups in improvement rates of daytime and nighttime pain. Both drugs were well tolerated. Conclusions: Revaprazan 200 mg was equivalent to omeprazole 20 mg for both ulcer healing and symptom relief, and was well tolerated in patients with duodenal ulcer.
