Phase 4 Study of Sto M Tab. in Acute or Chronic Gastritis
470 participantsStarted 2026-06
Plain-language summary
This Phase 4, multicenter, randomized, double-blind, active-controlled, non-inferiority study aims to evaluate the non-inferiority of Stoem Tab. compared to Stillen Tab. (Dong-A ST Co., Ltd.) in patients with acute or chronic gastritis. Participants will receive either Stoem Tab. or Stillen Tab. for 2 weeks. The primary outcome is the effective rate of gastric mucosal erosion at Week 2, assessed by upper gastrointestinal endoscopy and evaluated by an independent reviewer, defined as the proportion of participants achieving at least a 50% improvement in erosion score compared to baseline.

Inclusion criteria
. Male or female adults aged 19 to 75 years at the time of screening.
. Participants diagnosed with acute or chronic gastritis by upper gastrointestinal endoscopy performed within 7 days prior to randomization (Visit 2), with at least one gastric erosion confirmed. Erosions of the esophagus and duodenum are excluded.
. Female participants of childbearing potential or male participants who agree to maintain sexual abstinence or use appropriate contraceptive methods during the study period and for 2 weeks after the last administration of the investigational product. Periodic abstinence, such as calendar, ovulation, symptothermal, or post-ovulation methods, is not considered an acceptable contraceptive method.
. Participants who voluntarily provide written informed consent to participate in this clinical trial.
Exclusion criteria
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.
What they're measuring
1
Effective Rate of Gastric Mucosal Erosion Assessed by an Independent Reviewer
. Participants with any of the following lesions confirmed or accompanied by upper gastrointestinal endoscopy at screening (Visit 1): active or healing peptic ulcer; reflux esophagitis; Barrett's esophagus greater than 3 cm; gastroesophageal varices; esophageal stricture; or other clinically relevant lesions. Participants with ulcer scars may be enrolled.
. Participants who have a history of gastric acid secretion-inhibiting surgery or gastric or esophageal surgery at screening (Visit 1).
. Participants who have been diagnosed with or have a history of Zollinger-Ellison syndrome at screening (Visit 1).
. Participants with inflammatory bowel disease, such as Crohn's disease, ulcerative colitis, or intestinal Behcet's disease; primary esophageal motility disorder; or pancreatitis at screening (Visit 1).
. Participants with a history of malignancy within 5 years prior to screening (Visit 1). However, participants who have been completely treated and have had no recurrence for at least 5 years may be enrolled at the investigator's discretion. Participants with gastrointestinal malignancy are excluded regardless of the time since diagnosis. Participants with basal cell carcinoma, squamous cell carcinoma of the skin, thyroid cancer, or carcinoma in situ of other sites may be enrolled at the investigator's discretion if they have been completely treated and have had no recurrence for at least 3 years.
. Participants with current or prior thrombotic disease at screening (Visit 1), such as cerebral thrombosis, myocardial infarction, thrombophlebitis, or venous thrombosis.
. Participants diagnosed with disseminated intravascular coagulation at screening (Visit 1).
. Participants with concomitant hepatic, renal, cardiac, pulmonary, hematologic, or other diseases that, in the investigator's judgment, may affect the efficacy or safety evaluations.
