Study Endpoints

Primary Endpoints

Presence / absence of Erosive Esophagitis
Week 24 (end of 16-week maintenance phase)

Presence/absence of Erosive Esophagitis for all patients by assessment of Esophagogastroduodenoscopy at the end of the 16-week maintenance phase

Rate of Clinically Significant Rebleeding Within 72 Hours
72 hours

Diagnostic criteria for clinically significant rebleeding based on either A, B or C: A) Endoscopy - initiated by clinical signs of bleeding defined as one of B1 or B2 or B3 and endoscopic verification, ie one of A1 or A2. A1: Blood in stomach (this criteria cannot be used during the first 6 hours after primary endoscopic haemostasis). A2: A verified active bleeding from a peptic ulcer (Forrest Ia, Ib). B) A true clinically based definition, at least two of B1 and/or B2 and/or B3. B1: Vomiting of fresh blood or fresh blood in a gastric tube or haematochezia or melaena after a normal stool. B2: Decrease in Hb \>20g/L (or Hct \>6%) during 24 hours or an increase in Hb \<10g/L (or Hct \<3%) despite ≥2 units of blood has been transfused during 24hours. B3: Unstable circulation systolic blood pressure ≤ 90 mmHg or pulse ≥110/min (after have had a stable circulation). C) Haematemesis. Vomiting significant amounts (\>200 ml) of fresh blood as estimated by the investigator.

Frequently asked questions about Esomeprazole Na

What is esomeprazole Na used for in bleeding peptic ulcers?

Esomeprazole Na is being studied for the prevention of rebleeding after successful endoscopic therapy of a bleeding peptic ulcer. The Phase 3 trial enrolled 239 adults in China. It is an investigational use of the drug in this setting, and the trial has been completed.

What does esomeprazole Na target?

Esomeprazole Na targets ATP4A and ATP4B, subunits of the gastric proton pump. It acts as an inhibitor of this pump, which is the mechanism behind its suppression of gastric acid secretion. This target class is relevant to its evaluation in bleeding peptic ulcer.

Who makes esomeprazole Na?

Esomeprazole Na is developed by AstraZeneca PLC, which trades under the ticker AZN. The company is the sponsor behind the clinical program evaluating the drug in bleeding peptic ulcer.

What phase is esomeprazole Na in for bleeding peptic ulcer?

Esomeprazole Na is in Phase 3 development for bleeding peptic ulcer. The program includes one completed Phase 3 trial, and no trials are currently active. It remains an investigational use in this indication rather than an approved one.

What clinical trials is esomeprazole Na in for bleeding peptic ulcer?

Esomeprazole Na has been evaluated in the Phase 3 trial NCT01757275, titled High Dose Esomeprazole Na for Prevention of Rebleeding After Successful Endoscopic Therapy of a Bleeding Peptic Ulcer. The trial was completed, enrolled 239 participants, and was randomized, double blind, and active controlled.
