NAVIGATE Clinical Study
New clinical study for people with chronic nausea with or without vomiting.
Relief may be possible with Enterra® Therapy.

Now enrolling
The NAVIGATE Clinical Study is a prospective randomized controlled trial of chronic nausea, with or without vomiting, in patients with normal gastric emptying using Enterra® Therapy.
The purpose of the study is to determine if Enterra Therapy can decrease nausea and vomiting symptoms and improve the quality of life.
