1.   Lesogaberan add-on therapy to PPIs significantly improved heartburn and regurgitation symptoms; however, the proportion of responders was small. G.E.Boeckxstaens et al.: Gut 2011;60:1182-1188 "A  novel reflux inhibitor lesogaberan (AZD3355) as add-on treatment in patients with GORD with persistent reflux symptoms despite proton pump inhibitor therapy: a randomised placebo-controlled trial." Fll text

2. Compared with placebo, lesogaberan significantly reduced TLESRs and acid reflux episodes and increased LES pressure.
