Abstract

Background: Acotiamide, is the world's first-in-class, prokinetic drug and world’s first approved treatment for postprandial distress syndrome (PDS) symptoms of functional dyspepsia (FD). An extended-release (ER) formulation of this drug product, developed first-time in the world has been evaluated in phase 3, a comparative trial to explore the efficacy and safety in patients with FD-PDS.Methods: In this study, 219 patients with FD-PDS aged 18-65 years were randomized (1:1) to receive either acotiamide ER 300 mg once daily or acotiamide 100 mg three times daily for four weeks. The primary efficacy endpoint was responder rates for the overall treatment effect (OTE) at end of week 4. Secondary efficacy endpoints included OTE at each week, elimination rate of postprandial fullness, upper abdominal bloating and early satiation, improvement of individual symptom scores, and quality of life (QoL). The safety endpoints included assessments of treatment-emergent adverse events (TEAEs).Results: The responder rate for OTE at the end of the four week period, in acotiamide ER 300 mg OD versus acotiamide 100 mg TID group was 92.66% and 94.39% (97.5% CI −8.3,4.8), respectively, in per-protocol (PP) population and 92.66% and 92.73% (97.5% CI −7.0,6.8), respectively, in intent to treat (ITT) population. All other secondary efficacy endpoints, including QoL, were significantly improved with acotiamide ER 300 mg. Both the formulations of acotiamide significantly improved symptom severity and eliminated meal-related symptoms in patients with FD. Adverse events were reported by 7.9% of patients in acotiamide ER 300 mg and 9.2% in acotiamide 100 mg patients; the most common adverse event reported was a headache.Conclusions: The efficacy and safety of acotiamide ER 300 mg once daily were observed to be comparable to acotiamide immediate release 100 mg thrice daily. A significant improvement in QoL over a four-week treatment period in FD-PDS patients was observed.

Highlights

Functional dyspepsia (FD) is defined in accordance with the ROME IV criteria [1] as the presence of chronic symptoms of gastroduodenal origin without any explanatory organic or metabolic causes
Adverse events were reported by 7.9% of patients in acotiamide ER 300 mg and 9.2% in acotiamide 100 mg patients; the most common adverse event reported was a headache
In line with Rome IV, functional dyspepsia (FD) is subdivided into postprandial distress syndrome (PDS), which is characterized by mealinduced dyspeptic symptoms, and epigastric pain syndrome (EPS) characterized by meal unrelated symptoms [2] and respond differently to therapeutic interventions

Summary

Introduction

Functional dyspepsia (FD) is defined in accordance with the ROME IV criteria [1] as the presence of chronic symptoms of gastroduodenal origin (postprandial fullness [PPF], early satiation [ES], epigastric pain, and burning) without any explanatory organic or metabolic causes. FD is a common morbid condition and has an increased impact on the quality of life (QoL), healthcare, and socioeconomic costs. It is considered a heterogeneous condition in terms of the underlying pathophysiology and therapeutic approach. Acotiamide, is the world's first-in-class, prokinetic drug and world’s first approved treatment for postprandial distress syndrome (PDS) symptoms of functional dyspepsia (FD). An extended-release (ER) formulation of this drug product, developed first-time in the world has been evaluated in phase 3, a comparative trial to explore the efficacy and safety in patients with FD-PDS
