Treatment strategy of post endoscopic submucosal dissection (ESD) ulcer is not yet conclusive. Rebamipide is a mucosal protective agent widely used in East Asia and has good effect on quality of ulcer healing (QOUH). The investigators will conduct this randomized controlled study to assess the effect of a combination therapy of rebamipide and proton pump inhibitor (PPI) on post ESD ulcer healing.
A Prospective Randomized, Multi-center study to assess the Safety and Efficacy of Mucosta (Rebamipide), in combination with Omeprazole as adjuvant therapy in Gastric Ulcer Patients.
This study uses a randomized, double-blind, controlled design to demonstrate that PN400 (esomeprazole and naproxen) is more effective in reducing the occurrence of gastroduodenal ulcers, dyspepsia, and heartburn in subjects at risk for developing NSAID-associated gastric ulcers compared to naproxen alone.
LT-NS001 is a prodrug of Naproxen, which is inactive as a cox inhibitor while intact and is rapidly metabolized to Naproxen once absorbed. This trial will compare the rate of gastric ulcer by endoscopy over three months in patients with knee osteoarthritis, with patients receiving either LT-NS001 at a dose which provides comparable dose levels of Naproxen, or Naprosyn® 500mg (an approved treatment for OA).
Clopidogrel causes significantly less peptic ulcer disease (PUD) and ulcer bleeding than low-dose aspirin in general population. However, clopidogrel is not safe enough for gastrointestinal (GI) mucosa in patients who had past history of aspirin-associated ulcer or ulcer bleeding. Aspirin plus proton pump inhibitor (PPI) is superior to clopidogrel alone in preventing recurrent ulcer bleeding in these high risk patients. This study is to compare the ulcer healing rate and ulcer bleeding at 12 weeks in patients with aspirin-associated PUD when they take PPI (rabeprazole 20 mg/day) to treat their PUD and simultaneously take aspirin or clopidogrel for their cardiovascular (CV) prevention. Two hundred patients will be randomly assigned rabeprazole (20 mg/day) plus aspirin (100 mg/day) or rabeprazole (20 mg/day) plus clopidogrel (75 mg/day) for 12 weeks. The primary end point is treatment success (ulcer healing rate). The secondary end point is incidence of ulcer bleeding within 12 weeks. If rabeprazole plus aspirin in not inferior to rabeprazole plus clopidogrel in the incidence of ulcer healing and ulcer bleeding in the healing phase,PPI plus aspirin rather than PPI plus clopidogrel will be recommended during acute ulcer healing in patients who need antiplatelet therapy for their CV prevention.
This study uses an open-label design and will be conducted in approximately 40 sites in the United States. Approximately 400 subjects will be enrolled in the study to ensure that approximately 300 subjects will have 6 months exposure to PA32540 and at least 100 subjects will have 12 months exposure to PA32540.
Primary: To demonstrate that PA32540 causes fewer gastric ulcers in subjects at risk for developing aspirin-associated gastric ulcers compared to enteric coated (EC) aspirin 325 mg.

This study will evaluate the effect of Helicobacter pylori eradication therapy on the healing of iatrogenic gastric ulcer caused by endoscopic mucosal resection of gastric neoplastic lesions and is a multicenter, randomized, double blind, and placebo controlled trial.
