About
The primary objective of this randomized trial is to test whether a treatment with canakinumab is superior to placebo in patients with postprandial hypoglycemia after bariatric surgery, that is if it improves health related quality of life (mentally or physically) or reduces the risk of hypoglycemic events.
Full description
Postprandial hypoglycemia is a debilitating medical complication after bariatric surgery for which no approved pharmacological treatment exists. In a former study, the IL-1 receptor antagonist Anakinra statistically significantly reduced the number of symptomatic hypoglycemia.
This randomized clinical trial is to directly evaluate clinical outcomes and patient-relevant benefits of treatment with the IL-1 receptor canakinumab over 28 days. The primary objective of this randomized trial is to test whether a treatment with canakinumab is superior to placebo in patients with postprandial hypoglycemia after bariatric surgery, that is if it improves health related quality of life (mentally or physically) or reduces the risk of hypoglycemic events.
For each subject, a maximum study duration of four months is anticipated with: screening visit 1 (1 h), screening phase (10-day screening phase for postprandial hypoglycemia using a blinded continuous glucose monitoring system (CGMS, Dexcom G6)), randomization/starting visit (visit 2, 1.5 h) followed by a 28 days intervention period with two additional study days (visit 3 and 4, 0.5 h, change of blinded continuous glucose monitoring system (CGFS sensor), diary documentation, adverse events) and end of treatment visit (visit 5). A follow-up visit will be done two months after the end of the treatment phase.
