This phase III trial studies how well domperidone works in treating patients with gastrointestinal disorders. Domperidone may help control chronic gastrointestinal disorders and their symptoms, such as pain, bloating, and nausea and vomiting, by stimulating contraction of the stomach to increase its ability to empty itself of food.
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.
Erythromycin has a prokinetic effect through Motilin receptor. It evokes migrating motor complex with longer and stronger contraction. In patients with upper gastrointestinal bleeding, It has been shown that erythromycin could clear the stomach of blood, so visual examination could be improved. Frequent food stasis is encounted when we examine patients with subtotal gastrectomy. It is postulated that erythromycin reduce food stasis and help to improve endoscopy in these cases.
The proposed study will assess the efficacy and safety of the innovative endoscopic technique for the acquisition of full thickness gastric muscle wall biopsies. Having access to full thickness biopsies will allow an increased understanding of the pathophysiology of gastrointestinal diseases such as functional gastrointestinal disorders, gastroparesis, pseudoobstruction and other motility disorders. This information is essential to development of more targeted and effective therapy than currently available. Despite the high prevalence of functional gastrointestinal disorders and its significant impact on social and health care costs, the underlying cause is not well understood and there is no effective specific treatment to successfully alleviate patient symptoms.
Gastroparesis is a disorder characterized by delayed gastric emptying leading to symptoms of nausea, vomiting, bloating, and abdominal pain. A common cause is diabetes but even more often it occurs in otherwise healthy individuals. The symptoms of gastroparesis can significantly alter a patient's quality of life. Current therapies are limited. In this study, the investigators seek to determine if twice weekly acupuncture treatments can improve symptoms of gastroparesis.
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.
The purpose of this study is to determine whether Magnetic Marker Monitoring is an appropriate opportunity to diagnose and to quantify a suspicious gastroparesis in subjects with diabetic polyneuropathy.
Gastric emptying is the end-result of a complex and carefully regulated series of events which follow the ingestion of a meal, each of which is dependent on the other and subject to neurohormonal control. Motilin is an endogenous peptide, produced mainly in the duodenum, whose physiological action is mediated by motilin receptors located on enteric neurons, peripheral terminals of the vagus, and on the smooth muscle of the gut. Motilin and non-peptide agonists at motilin receptors increases the gastric emptying rate and therefore provide a potential approach to the treatment of a range of clinical conditions in which delayed gastric emptying is thought to be part of the physiopathology and may be contributory to symptoms. Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by degeneration of nigrostriatal dopaminergic neurones. It affects 1.5% of the global population over 65 years of age. Cardinal symptoms comprise bradykinesia, rigidity, resting tremors and postural instability. Gastrointestinal dysfunction, including gastroparesis, is a frequent feature of PD affecting approximately 90% of patients, and is caused by autonomic dysfunction as well as an adverse effect of antiparkinsonian drug therapy. The therapeutic mainstay for PD treatment is the neutral amino acid L-3,4-dihydroxyphenylalanine (L-DOPA), a dopamine prodrug, as it provides the most rapid and effective symptomatic control of motor impairment in PD. The primary determinant of L-DOPA bioavailability is gastric emptying (GE); delays in GE slow delivery of L-DOPA to its proximal small intestinal absorption sites, increasing the extent of presystemic metabolism, and leading to slowed and diminished absorption.
The purpose of this study is to evaluate the effects of RM-131 on gastric emptying, gastroparesis symptoms, and the safety and tolerability of RM-131 compared to placebo in patients with Type 1 and Type 2 diabetes mellitus and gastroparesis. The study is designed to evaluate the efficacy and safety of multiple dose regimens of RM-131. Study drug (RM-131 and placebo) will be administered subcutaneously in a blinded fashion.
