A Multicenter, Double-Blind, Randomized, Placebo-Controlled, Parallel-Group Phase 2 Study to Assess the Efficacy, Safety, and Tolerability of Velusetrag for the Treatment of Diabetic or Idiopathic Gastroparesis

Status: Completed
Intervention Type: Drug
Study Type: Interventional
Study Phase: Phase 2

Study 0099 explores the efficacy and safety of multiple doses of velusetrag in the treatment of symptoms in subjects with diabetic or idiopathic gastroparesis. Three dose levels of velusetrag will be evaluated and compared to placebo for approximately 12 weeks of therapy. In addition, the study will be used to evaluate the psychometric properties of the Gastroparesis Rating Scale (GRS), a daily patient-reported outcome (PRO) measure.
