- Abstract
Background Dexlansoprazole MR is a Dual Delayed Release formulation of dexlansoprazole, an enantiomer of lansoprazole, designed to extend the duration of acid suppression. Aim To assess the 12-month safety of dexlansoprazole MR in patients with symptomatic gastro-oesophageal reflux disease (GERD). Methods In this randomised open-label study, patients received dexlansoprazole MR 60 or 90 mg once-daily for 12 months. Safety was evaluated at months 1, 3, 6, 9 and 12/final visit through physical examinations, laboratory evaluations, endoscopies, gastric biopsies, fasting serum gastrin values and adverse events (AEs). Results Of 591 patients receiving dexlansoprazole MR 60 and 90 mg, 71% and 65%, respectively, experienced ≥1 treatment-emergent AE; the most frequent AE was upper respiratory infection (14% and 13% in the 60- and 90-mg groups). Thirty patients experienced ≥1 serious AE; a majority of serious AEs were unrelated to study drug. No clinically meaningful change in any clinical laboratory parameters was noted. As expected, serum gastrin values rose with dexlansoprazole therapy; increases were not dose related. No clinically concerning trends were identified in gastric pathology results; no endocrine cell hyperplasia, adenocarcinoma, or lymphoma were observed. Conclusions Twelve-month treatment with dexlansoprazole MR 60 and 90 mg was well tolerated by GERD patients in this study (Clinicaltrials.gov identifier NCT00255190).
