NCT06803589
The purpose of this study is to determine whether treatment with Growth Hormone results in symptomatic improvement in patients with gastroparesis.
NCT05229432
Purpose: The study is a cross-sectional observational study designed to determine if eosinophilic gastritis (EG) results in gastric motility impairment. Hypothesis: Gastric dysfunction occurs in the natural history of EG but is underdiagnosed due, in part, to contraindications to the use of the standard meals used in gastric emptying studies.
NCT03876288
GOLDEN is a longitudinal database of patients with the symptoms (Sx) of gastroparesis (Gp) who were seen and recorded at the University of Louisville from 2012 and is ongoing. Patients are enrolled and followed by sequential numbers and may include legacy patients seen at other centers by some of the same team and who are reported as part of the series. Outcome relate to patients Sx, survival, quality of life and other measures as detailed below, over time. The study tracks patients regardless of treatment but specifically focuses on GI Neuromodulation (gastric electrical stimulation - GES), Immunotherapy (IVIG), and Pyloric therapies (pyloroplasty, endoscopic). If treatments were administered GOLDEN allows for examination and stratification of outcome by groups both at baseline and at follow up.
NCT07287943
The goal of this clinical trial is to evaluate the efficacy and safety of Medtronic 780G automated insulin delivery system in adult persons with type 1 diabetes and gastroparesis.
NCT07324785
This study is a prospective observational study. The study will explore the correlation between advanced glycation end products and gastric motility disorder in diabetic gastroparesis（DGP) through the collection of blood and gastric tissue samples and relevant data of patients with DGP and control group patients without diabetes history and gastroparesis symptoms.
NCT05880199
The goal of this observational study is to learn about gastric myoelectric activity in children with GI symptoms. The main question it aims to answer is which patterns or signals are associated with GI symptoms as measured by a body surface gastric mapping (BSGM) device. Participants will have their stomach activity recorded for up to 4 hours using the BSGM device and log real-time symptoms. Researchers will compare the recordings of healthy children and children with GI symptoms to define abnormal GI patterns.
NCT04254549
Researchers are trying to determine if subjects with diabetic gastroparesis and symptoms of bloating will have a greater improvement in bloating symptoms when treated with rifaximin.
NCT04844190
The purpose of this study is to assess physiologic response of therapy in patients with refractory gastroparesis undergoing Gastric per-oral endoscopic myotomy (G-POEM) using endoscopic functional lumen imaging probe (EndoFLIP) and antroduodenal manometry (ADM). Refractory gastroparesis will be defined as having delayed gastric emptying at four hours (\>10% retention of stomach contents) on gastric scintigraphy and persistent symptoms despite treatment with dietary modification or prokinetic medications. We hypothesize that EndoFLIP and high resolution ADM will provide an individualized pyloric functional profile in gastroparesis patients that can more accurately predict clinical response to G-POEM.
NCT06292065
Glucagon-like peptide-1 (GLP-1) receptor agonists (GLP-1-RA) such as semaglutide (Ozempic™, Rybelsus™, Wegovy™) were first introduced as a therapeutic agent for type 2 diabetes mellitus but they are being increasingly used to target weight loss in obesity. One of the mechanisms by which weight loss is achieved, is increased satiety and significantly delayed gastric emptying. Tachyphylaxis for this effect has been reported with chronic use of long acting GLP-1-RA (e.g. semaglutide) but this was based on the paracetamol absorption technique or 13C breath test. Recent clinical data suggests semaglutide use does increase perioperative gastric content.This creates uncertainty for anaesthetists who are, anecdotally, more frequently faced with patients who may or may not have full stomachs despite adhering to conventional fasting guidelines. To address this issue the American Society of Anesthesiologists (ASA) has recently released guidelines in which it advises to hold GLP-1-RA for one day (if administered daily) or one week (if administered weekly). However, these recommendations are based on sparse empirical evidence and they do not necessarily follow from the known pharmacokinetic properties of these drugs. Typically, GLP-1-RA are administered in increasing doses over several weeks until a therapeutic steady state is achieved. Meanwhile the elimination half-life of e.g. semaglutide is 7 days. This means that holding semaglutide for one day or even one week might not be enough to attenuate its therapeutic effect of delayed gastric emptying. On the other hand if semaglutide were to be held for e.g. 5 terminal half-lifes, this would mean an unpractical 5 weeks during which glycemic control may be worsened and after which semaglutide doses would have to be incrementally increased again. Besides, hyperglycaemia secondary to semaglutide cessation can also delay gastric emptying. Further confounding the assessment of these patients there can be 'background' delayed gastric emptying in diabetic patients and more pronounced delayed gastric emptying in patients recently started on GLP-1-RA. The presence of gastro-intestinal symptoms (nausea, vomiting, dyspepsia, abdominal distension) might offer clinical information regarding increased gastric residue in this population. Gastric ultrasound is a point-of-care clinical and research tool that has steadily gained popularity to assess gastric content in patients not compliant with fasting rules or with certain comorbidities. Clinical decisions can be made based on the visualised content (e.g. solids, fluids or nothing) or through calculation of gastric volume by measuring antral circumference. In this study the investigators will examine gastric contents in patients who are taking semaglutide and in patients who are not. The investigators will then evaluate whether there is a difference in the incidence of full stomachs and whether gastric ultrasound influenced the anaesthetic plan of the treating anaesthetist.
NCT04028492
To investigate the safety and efficacy of tradipitant versus placebo in relieving nausea and other symptoms of gastroparesis.
NCT06965543
Gastroparesis, commonly caused by diabetes, affects 30-50% of diabetic individuals and complicates glycemic control due to its bidirectional relationship with blood glucose levels. Current treatments are often ineffective. G-POEM, a minimally invasive endoscopic technique, has demonstrated promising results in improving digestive symptoms, particularly in diabetic patients, with over 80% success. However, its impact on glycemic control has not yet been investigated, highlighting the need for further research.
NCT04300127
The principal objective of this pilot study will be to evaluate whether 8 weeks of treatment of pioglitazone will improve symptoms as measured by the Gastrointestinal Symptom Index (GCSI) in patients with Idiopathic Gastroparesis.
NCT06046833
A pilot study to evaluate and compare glucose metrics using a real-time continuous glucose monitor (FreeStyle Libre 3 sensor) between patients with diabetes and gastroparesis and those with diabetes without gastroparesis.
NCT06381349
Gastric peroral endoscopic myotomy (GPOEM) is a minimally-invasive procedure that involves dividing the pylorus, to enhance gastric emptying in gastroparesis patients. This is a single-arm, multi-centre, prospective observational study to determine the clinical utility of Gastric Alimetry in predicting GPOEM treatment outcomes. The investigators further aim to develop a clinical decision rule to inform patient selection. Gastric Alimetry will be conducted \<1 month prior to GPOEM. All subjects will then be followed up for 12 months.
NCT04869670
The purpose of this research is to evaluate the 12-month treatment effect of peroral endoscopic pyloromyotomy (G-POEM) vs. sham surgery in patients with gastroparesis that is not helped by medications and to analyze factors that may predict the outcome of the surgery.
NCT06854120
Functional dyspepsia and gastroparesis are common stomach disorders with symptoms like early satiety, nausea, and abdominal pain, and are often evaluated with gastric emptying tests, although the correlation with symptoms is weak. Prokinetic agents (e.g., metoclopramide, erythromycin) and symptom modulators (e.g., nortriptyline, mirtazapine) are commonly used, but selecting the right medication can be difficult, as it's often based on symptoms rather than the underlying gastric issues. Body Surface Gastric Mapping (BSGM) using the Gastric Alimetry device is a novel, non-invasive tool to assess gastric myoelectrical activity and symptoms. This study aims to perform two BSGM recordings-one before and one after medical therapy-to understand how medications affect gastric function and identify baseline BSGM factors that could predict responses to treatment, potentially guiding tailored therapies based on individual gastric dysfunction.
NCT04287647
This is a prospective sham study to investigate the role of transpyloric stenting with lumen apposing metal stent (LAMS) as a predictor for clinical response to gastric per-oral endoscopic pyloromyotomy (GPOEM) for refractory gastroparesis. The study hypothesizes that clinical improvement with transpyloric stenting in patients with refractory gastroparesis is a predictor of subsequent clinical success of GPOEM.
NCT05621811
This is a double-blind, randomized, multicenter, placebo-controlled, comparative phase II dose-finding trial. The trial will be conducted with four treatment groups in the form of a parallel group comparison and will serve to compare oral treatment with daily doses of 10, 20, or 40 mg Naronapride vs. placebo for the treatment of patients with Gastroparesis.
NCT04857281
The hypothesis of this pilot study is that nVNS will result in relief of nausea by modulation of vagal nerve activity. nVNS is the first non-invasive, handheld medical device applied on the side of the neck and sends gentle, patented mild electrical stimulation through the skin to activate the vagus nerve. nVNS offers a potential alternative to Gastric electrical stimulation (GES) that could eliminate significant risks of injury or illness or identify likely responders to implantable neurostimulator including implanted VNS (iVNS). nVNS could provide a more effective and safer alternative to the use of traditional rescue medications.
NCT04349891
Gastrointestinal (GI) dysmotility is common in GI motility disorders, such as functional dyspepsia (FD) gastroparesis and chronic constipation. The symptoms of GI dysmotility include abdominal discomfort or pain, early satiety, nausea, vomiting, abdominal distension, bloating, anorexia and reduced bowel movement. . Medical treatment for GI motility disorders is very limited in the US. Acupuncture has frequently been used for treatment of GI ailments in Eastern countries. The most commonly used acupuncture points (acupoints) for focused treatment of GI symptoms are the Neiguan (PC6) and the Zusanli (ST36) points. Electroacupuncture (EA) at PC6 and ST36 has been reported to accelerate gastrointestinal motility in both animals and human. Recently, the investigators have studied the feasibility of transcutaneous electroacupuncture (TEA): electrical stimulation is applied to acupoints via surface electrodes without needles, similar to the commercial available transcutaneous electrical nerve stimulation (TENS) but applied to acupoints. The investigators hypothesize that TEA as a new treatment option, improves GI symptoms in patients with FD, gastroparesis or constipation, improves GI motility and therefore improves quality of life of the patients. The success of this project will lead to a noninvasive and convenient therapy for treating GI motility disorders. The proposed TEA method is expected to improve gastric and colonic functions and thus improve quality of life. In addition, the proposed TEA method and device are self-administrative after training during the first office visit. It provides a long-term treatment option for both FD, gastroparesis and chronic constipation.
