Filter by:The investigators hypothesize that in adult patients with diabetic gastroparesis with Type 1 diabetes (HbA1c ≤ 10.5%), daily tadalafil use will significantly improve gastric emptying compared to baseline as measured by gastric emptying time.
Erythromycin is effectively used in the treatment of Gastroparesis (GP) patients. In susceptible patients however, it has been associated with sudden cardiac death due to prolongation of QT intervals and subsequent cardiac risks through its interaction some other drugs. Azithromycin (AZI) is a macrolide antibiotic but does not have the mentioned druf interactions , has fewer gastrointestinal side effects, and fewer risks of QT prolongation and cardiac arrhythmias. Consequently, AZI avoids drawbacks of dosing with erythromycin and may be preferred as a prokinetic agent in patients on other concomitant medications. We hope to demonstrate the effectiveness of Azithromycin (AZI) as compared to Erythromycin in the treatment of Gastroparesis (GP), and later, form the framework for larger randomized-controlled parallel studies to investigate use of AZI for treatment of GP. Our novel hypothesis is to determine whether AZI can be used to treat GP.
The primary objective of the study is to evaluate how patients with gastroparesis interpret the instructions, item content, and response options of a daily diary questionnaire designed to assess the key symptoms of gastroparesis.
This study is the First Time In Human study for the motilin receptor agonist, GSK1322888. GSK1322888 is a potent and selective small molecule motilin receptor agonist, distinct from the motilide compound structures. The aims of this study are to assess the safety, tolerance, and pharmacokinetics of single oral doses of GSK1322888 and to identify a well-tolerated and safe dose that will accelerate gastric emptying of a 13C stable isotope-labeled test meal in healthy volunteers. The study will include assessment of ECGs, vital signs, safety laboratory sampling, adverse events, pharmacokinetics, and the 13C-Octanoic Acid Breath Test to measure gastric emptying.
The purpose of this study is to assess the effectiveness of cisapride at improving symptoms associated with gastroparesis (a stomach disorder) in patients with diabetes mellitus.
The purpose of this study is to assess the effectiveness of cisapride in patients with a primary diagnosis of chronic gastroparesis (a stomach disorder) of unknown cause.
The purpose of this study is to determine the absolute oral bioavailability and intravenous pharmacokinetics of GSK962040. The oral dose of 50 mg has been selected because it was well tolerated following single oral administration and it is considered to be within therapeutic dose range. The need to characterize the intravenous disposition of GSK962040 is in anticipation of drug use in special populations such as critically.
GSK962040 is a novel small molecule motilin agonist. The Phase I studies (MOT107043 and MOT109681) demonstrated that single doses of GSK962040 up to 150 mg and repeat dosing of up to 125 mg/day for 14 days were well tolerated with adverse events not occurring in greater prevalence than placebo, and no significant abnormal vital sign, ECG, or clinical laboratory findings. Pharmacokinetic parameters were linear and approximately dose proportional over the range of doses administered. Single doses of 50 mg - 150 mg GSK962040 significantly increased the rate of gastric emptying up to 40% as measured by the 13C octanoic acid stable isotope breath test. A similar effect of 50 mg and 125 mg on gastric emptying was observed throughout repeated dosing to healthy volunteers for 14-days. The aims of the present investigation (MOT114479) are to assess the pharmacodynamic effects (gastric emptying and symptoms), safety, tolerability, and pharmacokinetics of GSK962040 after 28 days of once-daily dosing in Type I and Type II diabetic subjects with gastroparesis. An additional aim is to characterize the dose/exposure - pharmacodynamic effect relationship.
Pancreaticoduodenectomy (whipple procedure) is the standard operation for tumors of the pancreatic head, uncinate process, distal common bile duct as well as the papilla of vater. For reconstruction, pylorus-preservation (PPPD) has been shown to be technically and oncologically equivalent to the traditional whipple operation. One issue with this technique is delayed gastric emptying (DGE), which occurs in 25-70% of patients, usually emerging between day 4 and 14 after surgery. Patients with severe DGE can not only experience prolonged length of hospital stay, but are also at increased risk for other complications like aspiration or other issues related to the inability to ingest nutrition. There is vast retrospective evidence and one prospective study indicating that antecolic reconstruction of the duodenojejunostomy can improve the rate and severity of delayed gastric emptying. The investigators have conducted a prospective randomized trial in order to test this hypothesis. Patients were randomized to either undergo antecolic or retrocolic reconstruction after PPPD. On day 10 after surgery, DGE was assessed by clinical criteria. In addition, a test meal including 1g paracetamol was administered to check for clinically inapparent DGE. Of these serum samples, kinetics of intestinal peptides like GLP-1, PYY and glucagon was alos measured.
This study is designed to learn if hemin can increase the production of heme oxygenase 1 and improve gastric (stomach) emptying and symptoms in diabetic patients with slow gastric emptying (gastroparesis).
