Active clinical trials for "Gastroparesis"

This study will evaluate the safety and efficacy of relamorelin compared to placebo in participants with diabetic gastroparesis. Participants will report daily severity scores of their diabetic gastroparesis symptoms.

Gastroparesis is a disorder characterized by impaired gastric emptying in the absence of obstruction in the proximal GI tract. It is a common condition affecting up to 5 million persons in the United States alone. Despite this, metoclopramide is currently the only FDA approved medication for the treatment of gastroparesis. However, the evidence supporting metoclopramide in gastroparesis is fairly weak and was recently issued a black box warning because of potential irreversible side effects. There is clearly an urgent need for newer therapeutic options with better efficacy and tolerability. Olanzapine is a second generation anti-psychotic that is currently FDA approved for the treatment of schizophrenia and bipolar disorder. Because of actions at several receptors throughout the body, including dopamine and serotonin receptors, Olanzapine may provide anti-nausea and pro-motility effects in the stomach. Long-term use of olanzapine may also increase plasma levels of ghrelin. Ghrelin is a hormone produced by the gut that stimulates appetite and has also been shown to have beneficial effects on gastroparesis. The investigators hypothesize that olanzapine will be effective and safe in controlling symptoms as well as stimulate appetite and weight gain in gastroparesis. The investigators also hypothesize that olanzapine will stimulate gastric motility. Finally, the investigators hypothesize that olanzapine will modulate the secretion of ghrelin in gastroparesis. This pilot study may provide further information on the efficacy and safety of olanzapine in gastroparesis which could be utilized in a larger randomized, prospective study in the future.

42 patients admitted in ICU with intolerance to enteral feeding (GRV more than 250 ml) are recruited. All patients enter a primary acetaminophen absorption test study as baseline. Serum levels of acetaminophen will be measured by florescence polarization method at 15,30,45,60,90,120,180,240,480 minutes after enteral administration of 975 mg acetaminophen. Then the patients will be randomized to methylnaltrexone or erythromycin group.Another acetaminophen absorption test with the same schedule will be done after the last dose of each drug.The area under the curve for acetaminophen blood level will be used to compare the effect of two studied drugs on gastric emptying time.

The purpose of this study is to make Domperidone available to patients with gastrointestinal disorders who have failed standard therapy and who might benefit from it.

Enterra Therapy Gastric Simulation System (Enterra Therapy) is indicated for the treatment of patients with long term, uncontrolled (not helped by medication) nausea and vomiting from gastroparesis of diabetic or idiopathic origin. In March 2000, the Food and Drug Administration (FDA) gave approval of a humanitarian Device Exemption (HDE) of a Humanitarian Use Device (HUD) for Enterra Therapy Gastric electrical (GES) Simulation System. Although, there is evidence that suggests the use of Enterra Therapy System probably helps patients, symptoms, the FDA's HDE approval indicates that the helpfulness of this therapy has not been proven. Physicians at Columbia University Medical Center hope to prove the helpfulness of this device.

This study will assess gastric emptying in patients with symptoms of diabetic gastroparesis treated with tegaserod over 2 weeks.

Randomized controlled trial comparing haloperidol combined with conventional therapy and conventional therapy alone in patients with symptomatic gastroparesis.

The purpose of this study is to test the safety and effectiveness of 10 mg TZP-102 given prior to meals three times a day compared to placebo (capsule that looks like active study drug but contains no active drug), administered for 12 weeks, in diabetic subjects with symptoms associated with gastroparesis.

The purpose of this study is to create a new registry of patients with gastroparesis in order to better understand the characteristics of patients with gastroparesis and follow how their condition changes over time. The data collected may improve the understanding of the condition to enable better diagnosis and treatment.

This is a feasibility study to assess recruitment for a randomised control trial comparing prophylactic pyloric ballon dilatation versus control group (no intervention) in Ivor-Lewis Oesophagectomy
