Filter by:Proton pump inhibitors are administered to children as off-label use in Japan. The purpose of this study is to evaluate the effects of CYP2C19 genotypes on pharmacokinetic /pharmacodynamic profiles of PPI in children. The results will provide the beneficial information for the individualized medicine of PPI in children.
The primary objective of this study is to determine the accuracy of the Reflux Disease Questionnaire (RDQ) as a diagnostic test for gastroesophageal reflux disease. Symptom evaluation by the RDQ will be compared with other established approaches to the diagnosis of gastroesophageal reflux disease (GERD) in a primary care patient population with symptoms thought to be of upper gastrointestinal (GI) tract origin.
This study compares complete dissection of the tissue around the lower esophagus to no dissection of these tissues during laparoscopic fundoplication in children.
This study will investigate Gastroesophageal Reflux Disease (GERD)as a cause of sleep disturbance. Patients with GERD may experience all or some of the following symptoms: stomach acid or partially digested food re-entering the esophagus (which is sometimes referred to as heartburn or regurgitation) and belching. Even very small, unnoticeable amounts of rising stomach acid may cause patients to wake up during the night. This study will also investigate the effect of Rabeprazole, (brand name Aciphex) on patients with known insomnia. Rabeprazole is an FDA approved medication already marketed for the treatment of GERD.
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.
The purpose of this study is to evaluate changes in scores on the Reflux Finding Score and Reflux Symptom Index over a 24 week period. To enroll subjects must score at least a 13 on the Reflux Symptom Index and at least a 5 on the Reflux Finding Score. All subjects will receive education on lifestyle modifications with a nutritionist and exercise trainer. All subjects will be expected to comply with lifestyle modifications for the entire study period of 24 weeks. Half of all subjects will receive Prevacid 30mg BID and half will receive placebo BID for 24 weeks. Subjects will have 4 office visits over 24 weeks and weekly contacts with the study staff to assess Reflux Symptom Index and any health or medication changes.
The purpose of this study is to assess how PPI treated GERD patients with insufficient symptom control will benefit from a change in management by providing a more efficient acid secretion inhibition during 4 weeks, by evaluation of esomeprazole 40 mg compared to pre-study PPI treatment.
Gastroesophageal reflux disease (GERD) is a medical condition affecting the stomach and esophagus. GERD occurs when the lower esophageal sphincter does not close properly and stomach contents leaks back (refluxes) into the esophagus. GERD is one of the most common medical disorders, with estimates of up to 50% of adults reporting reflux symptoms. Proton pump inhibitors such as pantoprazole, can relieve symptoms of GERD in a large proportion of patients. Of particular interest in GERD is the assessment of symptom severity and quality of life, and the response to treatment. Therefore, a questionnaire was developed to assess GERD symptoms (`ReQuest TradeMark in Practice`). An important point to consider when using such a questionnaire is to follow the patients´ medical response to treatment and note whether a patient needs to change dosing, such as changing from full dose to half dose, or vice versa. The aim of the study is to determine the value of the questionnaire (`ReQuest TradeMark in Practice`) according to treating physicians` clinical judgment when using pantoprazole at full and half dose. The study duration consists of a pre-treatment periods (0-2 weeks) and two treatment period (8 weeks each). During the first treatment period, pantoprazole will be administered once daily at full dose (40 mg). During the second treatment period, pantoprazole will be administered once daily at half dose (20 mg). The study will provide further data on safety and tolerability of pantoprazole.
Gastroesophageal reflux disease (GERD) is a medical condition affecting the stomach and esophagus. GERD might occur when the lower esophageal sphincter does not close properly and stomach contents leaks back (refluxes) into the esophagus. GERD is one of the most common medical disorders, with estimates of up to 50% of adults reporting reflux symptoms. One of the main symptoms of GERD is heartburn. It occurs when the acidic content from the stomach touches the lining of the esophagus, causing a burning sensation in the chest or throat. Proton pump inhibitors such as pantoprazole can relieve symptoms of GERD and peptic ulcers in a large proportion of patients. Additionally, long-term treatment with proton pump inhibitors may be needed for patients with chronic ulcer disease not caused by H. pylori (H. pylori is a stomach-dwelling bacteria which is often associated with ulcers in the stomach or duodenum). The aim of the study is to evaluate the long-term effect of pantoprazole in patients with chronic gastric acid-related complaints. The study duration consists of a 5-year treatment period. Pantoprazole will be administered once daily. The study will provide further data on long-term safety, tolerability, and efficacy of pantoprazole.
The purpose of this study is to identify markers in the blood and tissue that could indicate risk factors for the development and progression of esophagus cancer. This research aims to collect medical history, blood, and tissue samples from patients who present with an esophageal disorder. Identifying genetic and behavioral risk factors involved in the development of esophageal cancer might allow for early detection and prevention. Survival and an opportunity for a cure with esophageal cancer will depend greatly on the stage of diagnosis. Tumors can develop changes in their genetic (hereditary) make-up, and these changes can sometimes be seen in normal tissues before the development of cancer. These genetic (hereditary) changes can serve as tumor markers and can be detected using methods that study changes in genetic material like DNA and RNA. The analysis of proteins can provide additional information. By identifying changes in these molecules that are different or altered in cancer, the investigators can use methods and tests for the detection of these changes.
