Active clinical trials for "Stomach Ulcer"

The purpose of this study is to study the safety and efficacy of TAK-438, once daily (QD), in participants with a history of gastric or duodenal ulcer requiring long-term NSAID therapy will be investigated.

The purpose of this study is to study the safety and efficacy of TAK-438, once daily (QD), in participants with a history of gastric or duodenal ulcer requiring long-term low-dose aspirin therapy will be investigated.

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.

Although stress ulcer is a complication that can cause significant mortality and morbidity in critical patients with risk factors, there is still lack of consensus about its prophylaxis. There are also few data available from Taiwan. H2 blockers are commonly used due to convenience. Some prefer sucralfate (a mucosal protective agent) for the sake of less association with nosocomial pneumonia. Recently, proton pump inhibitors were shown to have good prophylactic effects for stress ulcer. Pantoprazole (iv) is the first intravenous form of proton pump inhibitor that was approved by FDA. There are some reports about its application for treatment of peptic ulcer bleeding. It also has good acid suppression effect in patients under critical care. We expect that intravenous pantoprazole will have a role in stress ulcer prophylaxis. We will enroll those patients that have received major abdominal surgery and admitted to surgical ICU. After obtaining the consent, we will give them prophylactic drugs for 7 days within 24 hours. They are randomly allocated to 2 groups. Group I: pantoprazole 40 mg iv bolus stat and then qd ; Group II: famotidine 20 mg iv bolus stat and then q12h. We will monitor the following data: operation type & time, APACHE II score, CBC, CXR, stool character and OB test, NG aspirate. If clinical evidence of UGI bleeding occurs, endoscopic examination will be performed. We define the end point as overt bleeding, death or transfer out of ICU. We will compare the prevalence of UGI bleeding and ventilator associated pneumonia in these 2 groups

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.

Nonsteroidal anti-inflammatory drugs (NSAIDS) are often associated with gastric ulcers. This study looks at the treatment of these gastric ulcers with one of the three following treatment groups: esomeprazole 40 mg once daily; esomeprazole 20 mg once daily; or ranitidine 150 mg twice daily.

The purpose of this study is to investigate the efficacy of TAK-438, once daily (QD), compared to lansoprazole in patients with gastric ulcer.

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.

S-Tenatoprazole-Na (STU-Na), a new drug currently under clinical development, belongs to a class of drugs, called proton pump inhibitors (PPls). Some PPIs are already commercially available. STU-Na will be used for treatment of acid related diseases (gastroduodenal ulcers, erosive or ulcerative esophagitis due to gastroesophageal reflux disease). This study evaluates the degree of acid suppression by different doses of STU-Na. The degree of acid suppression is considered to be correlated with clinical efficacy. In this study four dosages of STU-Na (30 mg, 60 mg, 90 mg, and 120 mg) will be tested in each volunteer. First, one of the dosages will be orally administered for five days. Then, a nine to sixteen day period without study drug administration will follow prior to the administration of the next dosage, for again five days. Each volunteer will have a total of four study drug administration periods. After the last study drug intake in period 1, 2 and 3 pharmacokinetic blood sampling will be done for four days. After the last study drug intake in period 4 pharmacokinetic blood sampling will be done for five days. Pharmacokinetic blood sampling consists of several blood draws over a pre-determined time period. The pharmacokinetic blood sampling measures the medication concentration in the blood at pre-defined time points. After the last study drug intake in period 1, 2, 3, and 4, gastric acidity will be measured for 24 hours by means of a thin tube that will be inserted into the stomach through the nostril to evaluate the efficacy of the different dosages of STU-Na.

This study uses an open-label design and will be conducted in approximately 60 sites aiming to enroll a total number of 200 subjects to ensure that at least 100 subjects will have 12 months exposure to PN400 (VIMOVO).
