NCT01180179

Brief Summary

The aim of this study is to compare the efficacy of a proton pump inhibitor (lansoprazole) and a histamine-2 receptor antagonist (famotidine) in preventing recurrent ulcer bleeding in patients with a history of H. pylori-negative idiopathic peptic ulcers.

Outcome Measures

Primary Outcomes (1)

  • Recurrent ulcer bleeding

    According to prespecified criteria - hematemesis or melena documented by the admitting physician, or a decrease in the hemoglobin level of at least 2 g/dL, with ulcers or bleeding erosions confirmed on endoscopy. A prespecified interim-analysis is performed on the primary endpoint when all patients have been randomised and have completed the 12 months follow-up. The interim-analysis is performed by an independent statistician, blinded for the treatment allocation. The statistician will report to the independent data and safety monitoring committee (DSMC). The DSMC will have unblinded access to all data and will discuss the results of the interim-analysis with the steering committee in a joint meeting. The steering committee decides on the continuation of the trial and will report to the central ethics committee. The Peto approach is used: the trial will be ended using symmetric stopping boundaries at P \< 0.001.
