NCT ID: NCT02581696 Completed - Peptic Ulcer Clinical Trials

The Drug-drug Interaction and Safety of Lafutidine and Irsogladine Maleate in Healthy Adult Volunteers

Start date: August 2015
Phase: Phase 1
Study type: Interventional

An open-label, multiple-dose, single-arm, phase 1 study to evaluate the drug-drug interaction and safety of Lafutidine and Irsogladine maleate in healthy adult volunteers

NCT ID: NCT02551744 Completed - Peptic Ulcer Clinical Trials

Proton Pump Inhibitor Versus Histamine-2 Receptor Antagonist for the Prevention of Recurrent Peptic Ulcers

Start date: July 2012
Phase: N/A
Study type: Interventional

Whether pantoprazole versus famotidine for the prevention of recurrent peptic ulcers in thienopyridine users remains unclear.

NCT ID: NCT02536989 Completed - Hemorrhage Clinical Trials

Different Dose of Intravenous Omeprazole to Treat Bleeding Ulcer With Adherent Clot

Start date: March 2009
Phase: Phase 4
Study type: Interventional

The investigators will include those patients with adherent clot on gastric or duodenal ulcers after endoscopic confirmation After receiving well explanation and giving written consent, they are enrolled and will be allocated to 2 groups randomly. Those in the first group will receive intravenous omeprazole 40 mg stat and then 40 mg q12h. Those in the second group will receive intravenous omeprazole 80 mg stat and then 8mg/hr infusion. The patients in both groups will receive intravenous omeprazole for 3 days and then oral esomeprazole qd for further treatment of peptic ulcer. The investigators define rebleeding during admission and within 30 days as primary end points and define surgical intervention for ulcer bleeding, transfusion amount and hospitalization days after allocation as secondary end points.

NCT ID: NCT02456012 Completed - Clinical trials for Peptic Ulcer Hemorrhage

Long-term Oral Esomeprazole for Prevention of Peptic Ulcer Rebleeding in High-risk Patients

Eso_1y_R6PUB
Start date: April 2015
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine whether a long-term prophylactic use of esomeprazole 20 mg twice daily or once daily has prevention effectiveness in reducing the recurrence of peptic ulcer bleeding after ulcer healed with 16-week oral esomeprazole therapy in high-risk patients whose Rockall score ≥ 6.

NCT ID: NCT02436018 Recruiting - Gastric Cancer Clinical Trials

WEI NASAL JET for The Sedation of Outpatient Upper Gastrointestinal Endoscopy

Start date: March 2015
Phase: N/A
Study type: Interventional

Low pulse oximetry is the most common adverse events during sedation for upper gastrointestinal endoscopy. The main reason is the glossoptosis after sedation. In present study a new designed nasopharyngeal airway embedded with jet ventilation catheter(WEI NASAL JET) will be utilized in order to reduce the hypoxia. At the same time the safety will be evaluated.

NCT ID: NCT02434978 Recruiting - Clinical trials for Peptic Ulcer Bleeding

Doppler-guided Endoscopic Treatment in Peptic Ulcer Bleeding

Start date: January 2014
Phase: N/A
Study type: Interventional

The present study is a randomized controlled trial (RCT) that examines if the outcome of peptic ulcer bleeding could be improved by use of doppler-guided endoscopic treatment.

NCT ID: NCT02418312 Completed - Peptic Ulcer Clinical Trials

Efficacy of H2 Receptor Antagonist in Prevention of Thienopyridine-related Peptic Ulcer

Start date: January 2012
Phase: N/A
Study type: Interventional

Whether H2 receptor antagonist can prevent thienopyridine-related peptic ulcer remains unclear.

NCT ID: NCT02352155 Terminated - Ulcer Bleeding Clinical Trials

Second-look Endoscopy in High Risk Patients After Endoscopic Hemostasis to Their Bleeding Peptic Ulcers Improves Their Outcomes

Start date: February 4, 2015
Phase: N/A
Study type: Interventional

Bleeding peptic ulcer is a common medical emergency. Endoscopic treatment stops bleeding in those actively bleeding from their peptic ulcers, reduces further bleeding, transfusion, surgery and deaths. After initial endoscopic control of bleeding, approximately 10% of them will develop recurrent bleeding. Mortality rate in this group of patients is at least 4 fold higher. In the few who need surgery, mortality approaches 30%. Prevention of further bleeding is therefore a major treatment objective. Currently the investigators use a high dose infusion of proton pump inhibitor (PPI) for 72 hours to render gastric pH neutral. In a previous randomized trial, the investigators showed that the rate of bleeding in 30 days was around 7% with such an approach. In a small subgroup of high risk patients defined by presentation with shock and ulcers > 2 cm in size, 1 in 6 would re-bleed. An alternate strategy is to select those at especially high risk of further bleeding and repeat endoscopic treatment the next morning. The investigators have shown that persistence of major bleeding stigmata, i.e. a visible vessel, during a second endoscopy predicts further bleeding. It is therefore logical that by repeating endoscopic treatment the next morning, the investigators can prevent further bleeding and possibly surgery and deaths. The current study proposes to develop a score to identify those at risk of further bleeding after endoscopy. The investigators used a historical cohort with carefully collected clinical data to derive a risk score. In this derivation phase of 939 patients, the investigators have developed a 9 point risk score which consists of the following parameters (Age>60, Male sex, ulcer>2cm, posterior bulbar in location, spurting or Forrest Ia bleeding and admission hemoglobin of < 8 g/dl). Using AUROC and Youden J statistics, a score of 5 or above has been shown to highly predictive of further bleeding. The score will then be validated in a prospective cohort of patients with bleeding peptic ulcers. In the final phase of this study, the investigators propose a randomized controlled trial to test the hypothesis that a second look endoscopy with treatment in selected high risk patients can further reduce bleeding and improve their outcomes. After endoscopic hemostasis to their bleeding peptic ulcers, patients are risk stratified based on the score. Those with a score of 5 or more are randomized to receive the standard treatment (a high dose PPI infusion) or a second look endoscopy with treatment in addition to PPI infusion. The primary outcome to the trial is further significant clinical bleeding.

NCT ID: NCT02342470 Completed - Peptic Ulcer Clinical Trials

Efficacy and Safety of PMK-S005 in the Prevention of Recurrent Peptic Ulcer in Low-dose Aspirin Users

Start date: November 24, 2014
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the efficacy and safety by comparing prevention of recurrent peptic ulcer in low-dose aspirin users between PMK-S005 and Placebo.

NCT ID: NCT02332213 Completed - Colorectal Cancer Clinical Trials

Volatile Markers in Digestive Cancer

VOLGACORE
Start date: January 2014
Phase:
Study type: Observational

The study is aimed to determine the potential of volatile marker testing for identification of gastrointestinal cancers (in particular - colorectal and gastric cancers), the related precancerous lesions in the stomach and colon. The study will be addressing the role of confounding factors, including lifestyle factors, diet, smoking as well as addressing the potential role of microbiota in the composition of exhaled volatile markers.
