Condition(s) targeted: Gastroesophageal Reflux Disease
Intervention: AH23844 (lavoltidine) (Drug); NEXIUM (esomeprazole) (Drug); ZANTAC (ranitidine) (Drug)
Phase: Phase 1

Current treatment for gastroesophageal reflux disease (GERD) confirms an unmet need in
patients, based on slow onset of action and an inability to provide 24-hour gastric-acid
suppression. Clinical data on AH234844 demonstrates a rapid onset of action, high potency,
and prolonged duration of effect. The present study endeavors, in part, to compare
lavoltidine to two GERD drugs, NEXIUM and ranitidine.
Official title: A Three-Part Study in Healthy Male Volunteers to Determine the Most Effective of Four Different Lavoltidine Doses on Gastric pH and to Compare the Most Effective Dose With NEXIUM (Esomeprazole) 40mg for the Inhibition of Gastric-Acid Secretion and With Ranitidine (300mg/Day) for the Amount of Pharmacodynamic Tolerance
Study design: Diagnostic, Randomized, Double-Blind, Placebo Control, Crossover Assignment, Pharmacokinetics/Dynamics Study
