Marginal Ulcer Healing With Low-Thermal Argon Plasma Endoscopic Treatment
United States100 participantsStarted 2025-03-04
Plain-language summary
The objective of the study is to investigate the treatment of marginal ulcers with Low Thermal plasma in an endoscopic setting. By a treatment of the ulcerated areas with argon plasma with low power settings (\~ 1 W) we hypothesize that the size of the ulcers will shrink, and the healing is accelerated compared to standard of care alone. Patients will benefit from this minimally invasive approach compared to a much more invasive surgical approach that comes with higher risks and hospital stay length time. From a societal and scientific perspective, this study aims to extend the well-documented clinical benefits of plasma technology - from external wound healing to internal ulcer treatment - within an endoscopic framework. The success of this study could pave the way for broader applications of LTP in the treatment of other endoscopically accessible conditions such as peptic ulcers, duodenal ulcers and esophageal ulcers. This advancement has the potential not only to improve patient outcomes through less invasive methods, but also to position LTP as a cornerstone in the future of gastroenterological wound management strategies.

Inclusion Criteria:
* Subjects aged 18 years and above, inclusive of both males and females.
* Patients with a history of Roux-en-Y gastric bypass (RYGB) presenting symptoms indicative of marginal ulcers (MUs) such as abdominal pain, nausea, vomiting, gastrointestinal bleeding, or dysphagia.
* Subjects must be scheduled for an EGD for the evaluation of these symptoms.
* Marginal ulcers confirmed during the initial EGD.
* Willingness to adhere to the SOC treatment, which includes PPIs.
* Subjects able to tolerate repeated endoscopic procedures.
* Capacity for providing informed consent and understanding of study requirements.
* Willingness and ability to attend required follow-up assessments at 4 weeks (+/- 1 week) and 8 weeks (+/- 2 weeks).
Exclusion Criteria:
* Inability to provide informed consent.
* Unwillingness to undergo repeated endoscopies.
* Inability or unwillingness to comply with the SOC.
* Current use of systemic antibiotics.
* Any condition deemed by the investigator to compromise the safety of undergoing an endoscopic procedure.
* Pregnancy, lactation, or absence of reliable contraception in women of childbearing potential.
* Current enrollment in another investigational trial with potential to interfere with this study's endpoint analyses.
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?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
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.
