Not Applicable
Recruiting
Conditions
Gastroparesis Nondiabetic
Gastroparesis Due to Diabetes Mellitus
Gastroparesis
Interventions
Device: Enterra Therapy System
Registration Number
NCT06560307
Lead Sponsor
Enterra Medical, Inc.
Brief Summary

The purpose of this research study is to evaluate if an enhanced Enterra device programming strategy will improve symptoms associated with gastroparesis, improve symptoms in a faster amount of time, and improve quality of life measures.

Participants in this study will be evaluated for study entry criteria, have an Enterra Therapy System implanted, and be randomly assigned to one of two programming strategies. Participants will answer daily questions about their gastroparesis symptoms on an application with their phone/tablet. Participants will answer quality of life questionnaires about their gastroparesis symptoms at monthly study visits.

Participants will be involved in the study for up to six months after treatment assignment.

Programming parameters in the study are within currently approved labeling.

Exclusion Criteria
  1. Post-surgical gastroparesis (e.g., fundoplication, Billroth I or II) or other active stomach or gastrointestinal diseases disorders which could explain symptoms in the opinion of the investigator

  4. Active H. pylori infection

  5. Significant hepatic injury (elevated ALT, AST, bilirubin)

  6. Metabolic, mechanical, or mucosal inflammatory causes that may explain GI symptoms such as gallbladder disease, small bowel bacterial overgrowth, IBS, inflammatory bowel disease, celiac disease, liver or pancreatic disease, or bowel obstruction

  7. Patients with significant cardiac or cardiovascular disease, malignancy, or other conditions

  8. Participation in other clinical studies

  9. Use of narcotics more than three days per week or other drugs that may affect motility (e.g., Glucagon-like peptide 1 (GLP-1) agonist drug)

  10. Cannabis and/or cannabinoid use that exceeds either:

    1. Greater than 3 days of usage per week with 2 or less occurrences each day of use, or
    2. Greater than 3 grams of total usage per week
  11. Previous diagnosis or history of orthostatic intolerance, e.g., POTS, neurocardiogenic syncope, orthostatic hypotension

  12. Subject experiences discomfort during stimulation assessment that cannot be tolerated

  13. Subjects with an underlying disease leading to follow-up by MRI outside of current MR conditional indications

  14. Evidence of a failed response to temporary gastric electrical stimulation

GroupInterventionDescription
Control Programming StimulationEnterra Therapy SystemBegin with nominal (lower stimulation) programming settings at Enterra Therapy System implantation. At treatment assignment, nominal programming will continue. Slight increases in device amplitude (stimulation) will be done at 3 Month visit and at later follow-up visits.
Enhanced Programming StimulationEnterra Therapy SystemBegin with nominal (lower stimulation) programming settings at Enterra Therapy System implantation. At treatment assignment, moderate increases in device amplitude (stimulation) and duty cycle (on/off cycles) will be done. Further adjustments to amplitude, duty cycle, and/or frequency (rate of pulses) will be done at follow-up visits.
