Post Bariatric Hypoglycemia

The Expanded Access Program will provide access to avexitide for people with post-bariatric hypoglycemia (PBH) following Roux-en-Y gastric bypass (RYGB) who meet the eligibility criteria for this program. The safety of avexitide and patient treatment experience will be monitored during this program.

Late dumping syndrome is a common complication following Roux-en-Y gastric bypass, characterized by postprandial hypoglycemia with significant impact on patient safety and quality of life. Traditional capillary glucose monitoring has limited ability to detect rapid glycemic fluctuations. This prospective randomized study aims to evaluate the efficacy and safety of the iCan i3 continuous glucose monitoring (CGM) system compared to conventional capillary glucose monitoring in detecting hypoglycemic events in post-bariatric patients with late dumping syndrome. Participants will be randomized into two groups: one using CGM and one using standard fingerstick monitoring, and followed for 60 days. Clinical outcomes, hypoglycemia frequency, symptom correlation, and quality of life will be assessed.

Severe hypoglycemia (low blood sugar)after gastric bypass surgery is an increasingly recognized condition, characterized by symptoms of hypoglycemia after eating and inappropriately elevated insulin concentrations that occur at the time of hypoglycemia. Severe hypoglycemia can be dangerous and debilitating and can also impact cognitive function. At the moment no medical therapies have been developed for this disorder. Determining why some but not other patients develop this condition would allow for improved prediction, prevention, and treatment approaches. The purpose of the study is to understand the physiological changes observed in those patients who undergo gastric bypass and develop symptomatic hypoglycemia.
