Is this trial a fit for you?

Likely a good fit

Ideal candidates for this study are adults aged 22 years or older who present with acute overt gastrointestinal bleeding due to gastric or duodenal ulcers.

Probably not a fit

What this trial studies

This clinical trial is a multi-center, noninferiority randomized controlled trial that aims to evaluate the effectiveness of UI-EWD hemostatic powder (Nexpowder™) compared to conventional endoscopic hemostatic therapy in patients with acute gastrointestinal bleeding due to gastric or duodenal ulcers. Participants will be adults presenting with active bleeding or a non-bleeding visible vessel identified during endoscopy. The study will assess the primary outcome of hemostasis and rebleeding rates between the two treatment approaches. The trial is designed to provide insights into whether the new powder can serve as an effective first-line therapy.

Why it matters

Potential benefit: If successful, this study could provide a more effective treatment option for patients with acute gastrointestinal bleeding, potentially reducing rebleeding rates.

How similar studies have gone: Previous studies have shown promising results with UI-EWD hemostatic powder, indicating that this approach may be effective, though this specific comparison is novel.

2. Presentation with acute overt gastrointestinal bleeding (hematemesis, melena, and/or hematochezia)
3. Subject voluntarily agrees to participate in the clinical investigation, provides written informed consent, and will be able to comply with the investigational protocol in the opinion of the site investigator
4. Cause of bleeding as determined at upper endoscopy is one of the following sources: a gastric or duodenal ulcer with active bleeding (spurting or oozing) or a non-bleeding visible vessel; an esophageal, gastric or duodenal tumor with active bleeding or a non-bleeding visible vessel; a gastric or duodenal Dieulafoy lesion with active bleeding or a non-bleeding visible vessel; or an actively bleeding Mallory-Weiss tear. The definition of "active oozing" will require bleeding to persist for ≥ 3 minutes of endoscopic observation.

Exclusion Criteria:

3. Pregnancy or nursing mothers
4. Endoscopic hemostatic treatment in the past 30 days

7. Post-polypectomy bleeding
8. Subjects with erosive esophagitis, erosive gastritis, esophageal ulcer, or vascular ectasia including gastric antral vascular ectasia
9. Platelet count \< 50 x 10\^9/L
10. INR \> 3.5 (or prothrombin time \>35 seconds in patient not on warfarin and only prothrombin time is provided by local lab), at time of procedure or closest to procedure time
11. Subjects who have documented galactose intolerance, Lapp lactase deficiency or glucose-galactose malabsorption
12. Subjects with documented hypersensitivity to Brilliant Blue FCF
13. Subjects with suspected bowel obstruction or gastrointestinal fistulas, and those suspected or are at high risk of having gastrointestinal perforation.
14. Endoscopy not performed within 36 hours of presentation to hospital/emergency department
