Endoscopic Injection of Autologous Fat-Derived Cells (SVF) for Adults With Refractory Gastroesophageal Reflux Disease (GERD). (The GERD-REVIVE Pilot Study)
15 participantsStarted 2026-07
Plain-language summary
The purpose of this pilot clinical study is to evaluate the feasibility and safety of an innovative endoscopic treatment for adults with gastroesophageal reflux disease (GERD) that does not respond adequately to standard medications. The study focuses on the anti-reflux barrier between the esophagus and the stomach, which fails in patients with GERD. Instead of traditional surgery, this study explores a minimally invasive approach: injecting a specialized mixture of the patient's own fat-derived cells-known as the Stromal Vascular Fraction (SVF)-directly into the tissue at the esophagogastric junction during a standard endoscopy. The study is trying to answer two primary questions: Is it clinically feasible and safe to harvest, process, and endoscopically inject autologous SVF cells to support the anti-reflux barrier? Can this cell-based intervention help repair the tissue and improve the mechanical function of the barrier, allowing patients to reduce or completely stop their daily reliance on proton pump inhibitors (PPIs)? By answering these questions in a small group of 15 participants, this pilot trial aims to provide the foundational data necessary to design larger clinical studies in the future.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:

* Refractory symptoms on optimized PPIs or PPI-dependent disease where intervention is contemplated. \[2\]
* HRM excluding major motility disorders (per Chicago v4.0). \[21\]
* Willing to undergo adipose harvest and autologous SVF therapy within a clinical trial framework.
Exclusion Criteria:
* Hiatal hernia \>3 cm or paraesophageal hernia; severe esophagitis with ulcers (grade B or more); Barrett's with dysplasia; strictures; achalasia/EGJOO/spastic disorders. \[2,21\]
* Coagulopathy, uncontrolled cardiopulmonary disease, pregnancy/lactation.
* Active infection/malignancy significant for increased risk, at PI discretion.
* Prior fundoplication or magnetic sphincter augmentation within 12 months.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
