Jun 15Top-line results from the RHB-105 PIII study was designed to evaluate the safety and efficacy of RHB-105 as a first-line treatment for confirmed H. pylori infection. A total of 118 dyspepsia pts with confirmed H. pylori infection were enrolled and treated in the ERADICATE Hp study. Pts were randomised in a 2:1 ratio to receive either RHB-105 or a placebo for 14 days, and assessed for the eradication of H. pylori infection 28 to 35 days after completion of treatment.

The study successfully met its primary endpoint of superiority over historical standard of care efficacy levels of 70% (p<0.001). No serious adverse events or unexpected safety issues were identified. Full results from the RHB-105 PIII study are expected in the third quarter of 2015 [6].
