Filter by:This study is designed to evaluate the efficacy, safety and pharmacokinetics of subcutaneous exendin (9-39) in subjects with post-bariatric hypoglycemia. Development of this subcutaneous formulation of exendin (9-39) would represent a targeted therapeutic approach for this rare disease with unmet clinical need.
This research study is designed to investigate the effect of hypoglycemia (low blood sugar) on blood flow to and biochemistry in the brain.
Approximately 25% of patients with type 1 diabetes have lost the capacity to timely detect hypoglycaemia, a condition referred to as impaired hypoglycaemic awareness (IHA) that causes a six-fold higher risk of severe, potentially hazardous, hypoglycaemia. IHA is usually the end-result of a process of habituation to recurrent hypoglycemia that is potentially reversible. Treatment with glucagon-like peptide (GLP)-1 Receptor Agonists (1RAs) in addition to insulin therapy may decrease the incidence of hypoglycaemia in patients with type 1 diabetes. This study will test the hypothesis that treatment with the GLP-1RA, exenatide, added to basal-bolus insulin therapy will improve awareness of hypoglycaemia in patients with type 1 diabetes and IHA. In a randomized doubleblind placebo-controlled cross-over trial, patients will be treated for 6 weeks with exenatide (or placebo), after which hypoglycemic symptoms and counterregulatory hormone responses will be examined during a hyperinsulinemic hypoglycemic glucose clamp study.
Hypoglycemia is an increasingly recognized complication of Roux-en-Y gastric bypass (RYGB) that is poorly understood and difficult to treat. Investigators hypothesize that after RYGB some patients have incomplete carbohydrate absorption in the small intestine which leads to inconsistent glucose levels and hypoglycemia during oral consumption of a meal. Investigators further hypothesize that pancreatic enzyme supplementation with (Creon) during meals and snacks will improve carbohydrate absorption and lead to more stable glucose levels in patients with post-RYGB hypoglycemia.
The primary objective of this study is to test an optimized control system for sensor-guided (physician administered) delivery of glucagon, and test Proof-of-Concept (POC) in a clinical setting in patients with severe hypoglycemia following bariatric surgery.
Objective: to gain experience in children and younger adolescents with in-home use of an algorithm that will dose insulin to minimize projected hyperglycemia overnight in addition to suspending the pump if hypoglycemia is projected overnight and to obtain feasibility, safety, and initial efficacy data Study Design: randomized controlled trial, with randomization on a night level within subject Patient Population: Youth 6.0 - <15 years old with type 1 diabetes treated with daily insulin therapy for at least one year and an insulin infusion pump for at least 6 months who have HbA1c < 10.0%. Sample Size: 30 subjects Study Duration and Visit Schedule: duration approximately 3 months, with preliminary run-in activities followed by up to 90 days spent in clinical trial phase of study; clinic visits at enrollment, following CGM and system assessment run-in phases, at start of clinical trial phase, at 21-day point of clinical trial phase, and after 42 nights of successful system use Major Efficacy Outcomes: - Primary: time in range (70-180 mg/dl, 3.9-10.0 mmol/L) overnight. - Secondary: time spent in hypoglycemia (<70 mg/dl, 3.9 mmol/L) and time spent in hyperglycemia (>180 mg/dl, 10.0 mmol/L) overnight. Major Safety Outcomes: CGM measures of hypo- and hyperglycemia, including morning blood glucose and mean overnight sensor glucose; adverse events including severe hypoglycemia and diabetic ketoacidosis
This is a single center, single-blind randomized cross over design trial that will compare the impact of intra-nasal naloxone vs. intra-nasal saline administration during experimental hypoglycemia on day one on responses to experimental hypoglycemia on day two. Investigators intend to enroll 18 individuals to obtain the complete data sets from 15 participants. Expected duration of subject participation is 10-12 weeks. This study will consist of two 2-day intervention visits separated by approximately 8 weeks.
Hypoglycemia-associated autonomic failure (HAAF), a condition commonly developed in diabetic patients, which causes them to have severely low blood sugar levels. This condition makes clinical management of blood sugar in diabetic patients very challenging. This research seeks to better understand how diabetic patients develop HAAF, and what can be done to prevent it.
Growing evidence provided by many observational studies has established a strong link between decreased sleep duration and poor glucoregulation. Sleep deprivation and poor sleep quality induce insulin resistance and decrease glucose tolerance in healthy individuals. However, the influence of poor sleep quality on glycemic control of patients with Type 1 diabetes mellitus (T1DM) is unknown. Persistent sleep deprivation among patients with T1DM has been reported, and this sleep loss can be attributed in part to nocturnal hypoglycemia. Nocturnal iatrogenic hypoglycemia is a limitation of current intensive insulin therapies. Although severe hypoglycemia is associated with adverse events such as seizures and death, less severe nocturnal hypoglycemia has been linked to broad range of adverse consequences, both acutely and long term. Hypoglycemia stimulates the sympathetic nervous system as a stress response, leading to the stimulation of the hypothalamic-pituitary-adrenal axis (HPA). This results in a counter regulatory hormone cascade, which elicits an excessive cortisol secretion, which is known to cause sleep disturbance and could impair glucose homeostasis after the hypoglycemic event. The hyperinsulinemia in T1DM patients promotes HPA hyperactivity as well, which is also associated with impaired sleep quality by leading to sleep fragmentation, decreased slow wave sleep and shortened sleep duration. Sleep disturbances due to nocturnal hypoglycemia can exacerbate HPA axis dysfunction, adversely affecting the sleep-wake cycle. The goal of the study is to understand the impact of nocturnal hypoglycemia on sleep.
The purpose of the study is to evaluate the effectiveness of exenatide in adults experiencing episodes of hyperinsulinemic hypoglycemia following Roux-en-Y bariatric surgery.
