Active clinical trials for "Gastroesophageal Reflux"

Gastro-esophageal reflux disease (GERD) is highly prevalent, affecting up to 20% of the adult population in North America. Up to 70% of GERD patients have non-erosive reflux disease (NERD), a term used to describe symptoms suggestive of GERD in patients with no endoscopic evidence of erosive esophagitis. NERD represents a heterogeneous group of patients whom are sub classified according to 24 hours-PH monitoring results and also symptom-acid association analysis(Symptom Index,SI). Treatment of NERD can be a challenge for clinicians. According to the many studies , the pooled rate for symptomatic response after a period of proton pomp inhibitor(PPIs)therapy as the most frequently used drug, in NERD patients is lower than for erosive esophagitis patients. It is also shown that acid exposure is much lower in NERD patients than those with erosive esophagitis and NERD patients are less likely to exhibit a strong association between heartburn symptoms and acid reflux events than patients with erosive oesophagitis. Furthermore, beside the high economic burden, there are concerns about the adverse effects of long time administration of PPIs. Several hypothesis has been proposed to describe low response rate of NERD patients to PPIs. One of the most acceptable theories is that patients with anxiety or depression and psychological problems are at an increased risk of developing reflux symptoms. On the other hand, pain modulators such as sertraline, a selective serotonin reuptake inhibitor(SSRI), and other antidepressants have been shown to improve symptoms in patients with functional gastrointestinal disorders like non cardiac chest pain. According to the above-mentioned tips, the investigators hypothesize that antidepressants like fluoxetine, as an SSRI, may have beneficial effects in improving symptoms of NERD patients. The purpose of this study is to compare the effect of omeprazole with fluoxetine and placebo for treatment of NERD patients and its subgroups who all experience reflux symptoms and have normal endoscopic findings.

The purpose of this study is to determine whether Dexlansoprazole once daily (QD) is effective in treating patients with night heartburn.

The purpose of this study is to investigate the efficacy (ie, healing and symptom relief) and safety of Rabeprazole Extended-Release (RAB ER) 50 mg versus Esomeprazole (ESO) 40 mg for the treatment of moderate to severe erosive Gastroesophageal Reflux Disease (eGERD).

This study looks at the effect on basal and pentagastrin-stimulated acid output of 40 mg Esomeprazole (Nexium) administered orally and intravenously as a 15-minute infusion to people with symptoms of Gastroesophageal Reflux Disease (GERD)

The primary objective of this study is to investigate whether eradication treatment of Helicobacter pylori followed by therapy with esomeprazole for a total of 8 weeks extends the time to relapse in patients with gastroesophageal reflux disease (GERD). A relapse is defined by two consecutive symptom scores of the Eraflux questionnaire within 14 days that are equal or above the critical value of 25. The secondary objectives are To compare the time to relapse in the two H. pylori positive study groups with the H. pylori negative control group To compare the pattern of inflammation and atrophy in the two H. pylori positive treatment groups with the naturally H. pylori negative control group at relapse. All the above objectives analyzed for the efficacy subset that is the per-protocol patients broken down by effective H. pylori-eradication. Secondary endpoints will be analyzed by the following parameters and their interactions: Treatment : Eradicated, Non-eradicated, Hp-negative control Esophagitis at study start: grades 0, A/B and C/D Gender Alcohol intake NSAID/ASA intake (for histological results) Trial with medicinal product

The purpose of this prospective, multicenter study was to evaluate the safety and efficacy of endoscopic full-thickness plication for the treatment of symptomatic gastroesophageal reflux. Sixty-four patients were enrolled and underwent endoscopic full-thickness plication. All patients received a single implant/plication. No repeat plication procedures were performed. Primary efficacy in this study was measured by the percent reduction in post-procedure GERD symptoms as evidenced by analysis of the GERD-HRQL (Health Related Quality of Life) questionnaire. Secondary efficacy outcomes included post-procedure reduction in anti-secretory therapy, improvement in quality of life questionnaires, reduction in distal esophageal acid exposure, and improvement in esophageal manometry. Patient follow-up assessments were completed at 1, 3, 6 and 12 months post treatment.

The purpose of this study is to evaluate the pharmacokinetics, pharmacodynamics, and the safety of rabeprazole sodium for the treatment of gastroesophageal reflux disease (GERD) in newborns and pre-term infants.

Evaluation of the effect of ADX10059 on symptom control in patients with gastroesophageal reflux.

The purpose of this study is to investigate the superiority of efficacy of TAK-438, once daily (QD), to placebo in patients with non-erosive gastroesophageal reflux disease.

The purpose of this study is to investigate the pharmacodynamics (PD) and pharmacokinetics of E3710 following oral administration to Healthy Male Japanese Subjects
