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.
NCT06803589
The purpose of this study is to determine whether treatment with Growth Hormone results in symptomatic improvement in patients with gastroparesis.
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.
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.
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.
NCT06038734
Given the increased prescription of GLP-1 agonists for both diabetes and obesity management and the implications of the proposed delayed gastric emptying in the setting of an anesthetic, it is critical to determine if patients taking GLP-1 agonists have an increased rate of delayed gastric emptying. The purpose of this prospective gastric ultrasound evaluation of pre-operative patients is to determine the incidence of a full stomach despite a standard pre-operative fasting period.
NCT06394154
This study aims to validate the Alimetry® Gut-Brain Wellbeing Survey- Youth Version (AGBW-Y), a mental health scale developed for patients aged 12-17 years with chronic stomach symptoms.
NCT06340828
The goal of this clinical trial is to learn about effectiveness and safety of washing microbiota transplantation in diabetic gastrointestinal motility disorders participant population. The main questions it aims to answer are: * The risk factors of diabetic gastrointestinal motility disorders in routine clinical data or biochemical tests. * The composition of gut microbiota in diabetic gastrointestinal motility disorders patients and potential pathogenic bacteria. * The efficacy of washing microbiota transplantation in the clinical treatment of diabetic gastrointestinal motility disorders patients and potential factors that may influence treatment outcomes. * The potential mechanisms of washing microbiota transplantation in treating diabetic gastrointestinal motility disorders patients. Participants will be collected fasting venous blood and random stool samples before treatment and at week 12 post-treatment, conducting scale assessments before treatment and at weeks 1, 4, and 12 post-treatment.
NCT05229107
This study will explore the use of Cereset Research for symptoms associated with refractory chronic nausea in patients with gastroparesis (GP) in a randomized, clinical trial.
NCT03531450
This is a single-center pilot study to be conducted at Massachusetts General Hospital. The purpose of this study is to examine the non-pharmacological impact of Cognitive Behavioral Therapy (CBT) on gastroparesis symptoms and other clinical co-comorbidities such as pain, depression, anxiety, and catastrophizing. CBT trial patients will undergo careful phenotyping pre- and post- intervention with brain MRI, autonomic function test (AFT), gastric emptying scintigraphy (GES), and nutrient drink test (NDT) to determine the impact of CBT on these metrics in patients with gastroparesis. Characterization of these relationships or lack thereof can help guide future development of more targeted approaches and optimize treatment strategies for gastroparesis.
NCT05795309
This is a staggered randomised controlled trial that aims to assess the impact of an automated insulin delivery (AID) system on glucose, gastrointestinal and patient-reported outcomes.
NCT04977063
This study will compare gastrointestinal transit time measured by the SmartPill and the Atmo gas capsule in patients with gastrointestinal motility disorders. Both of these devices allow gastrointestinal transit time to be measured, however the SmartPill senses pH changes whereas the Atmo Capsule measures gas profiles. A total of 60 participants (30 diagnosed with gastroparesis, 30 with slow transit constipation) will attend Macarthur Clinical School at Western Sydney University after an overnight fast. Participants will consume a standardised meal before ingesting the SmartPill and Atmo Capsule. Each participant will carry a data receiver until passage of the capsules. Anatomical landmarks will be defined by pH changes (SmartPill) or oxygen profiles (Atmo Capsule). Statistical analysis will be performed via linear regression and degrees of agreement for measurements between the two devices. Primary end-points will be the agreement between gastric emptying, small intestinal and colonic transit times generated by the devices.
