Detailed Description:

Participants in this study will have an Enterra® Therapy System implanted and be assigned to a study group. Participants will answer daily questions about their nausea and vomiting symptoms and quality of life impacts with their smart device. Participants will answer quality of life questionnaires about their symptoms at study visits. Participants will be involved in this study for approximately twelve months after their study group is assigned.

Study Type : INTERVENTIONAL
Estimated Enrollment : 148 participants
Masking : QUADRUPLE
Masking Description : Delegated site personnel will be unblinded to subject treatment assignments to appropriately program their Enterra Therapy System, per study requirements. Unblinded site personnel will be the only role delegated the responsibilities of randomizing subjects to a treatment assignment, performing device interrogations, and completing device programming at study visits according to the randomization assignment.
Primary Purpose : TREATMENT
Official Title : A Prospective Randomized Controlled Trial of Chronic Nausea and Vomiting in Patients With Normal Gastric Emptying Using the Enterra® Therapy System
Actual Study Start Date : 2025-06-23
