Washington University 5-year Study on Enterra Therapy (2024)

Study Objective

Examining clinical outcomes of Enterra Therapy in the treatment of patients with chronic, intractable (Refactrory to 2x Drug Clases extending past 6 months) gastroparesis

Study Design

Prospective data from large (n=157), tertiary academic, single-center, 1 & 5 year follow-up on Enterra Therapy

Primary Endpoint

Gastroparesis Cardinal Symptom Index (GCSI) Score at 1 & 5 years vs. Baseline

Results:

Patients with gastroparesis treated with Enterra Therapy showed statisticaly significant improvements in GCSI Total Score and Nausea-Vomiting Subscores at both 1 and 5 year follow-up.

Key take-aways:

  • In this independently conducted, prospectively collected study of 157 gastroparesis patients examining clinical outcomes of Enterra Therapy, patients receiving Enterra Gastric Electrical Stimulation Therapy showed statistically significant improvements in all Gastroparesis Cardinal Symptom Index (GCSI) scores at 1 year and 5 year follow-up.
    • All GCSI Subscales – Nausea/Vomiting; Postprandial Fullness, and Bloating subscales — showed statistically significant improvement at 1 and 5 year follow-up periods. 
  • Statistically significant improvement in percent of patients hospitalized for gastroparesis & number of hospitalizations at both 1 and 5 year follow-up.
  • In 141 patient cohort with both baseline and 1 year follow-up data, total number of hospitalization events showed significant 91% reduction in patients treated with Enterra Therapy.
  • High-patient satisfaction of 87.1% and 79.7% reported by patients at both 1 and 5 year follow-up.

IMPORTANT SAFETY INFORMATION

The Enterra Therapy System for gastric electrical stimulation (GES) is indicated for the treatment of chronic intractable (drug refractory) nausea and vomiting secondary to gastroparesis.
