About this trial
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.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Patients after bariatric surgery (i.e. sleeve gastrectomy, Roux-en-Y gastric bypass, omega-loop bypass, biliopancreatic diversion) with documented hypoglycemia, i. e. < 3.0 mmol/l and at least 5 hypoglycemic episodes per week despite dietary modification
For women with child-bearing potential, willingness to use contraceptive measures adequate to prevent pregnancy during the study
Informed Consent as documented by signature
Disqualifiers
Any type of diabetes mellitus according to ADA criteria
Intolerance to the study drug
Signs of current infection
Any use of immunosuppressive medication

Treatments tested in this trial
Canakinumab
DrugCanakinumab (Ilaris®, Novartis Switzerland) will be used in the recommended standard dose of 150 mg subcutaneously once. Patients will be randomized at visit 2 = Baseline to either placebo (1 ml 0.9 % saline solution s.c.) or treatment with 1 ml 150 mg canakinumab solution s.c. in a 1:1 manner.
Placebo (0.9% NaCl)
Drug1 ml 0.9 % saline solution s.c. Patients will be randomized at visit 2 = Baseline to either placebo (1 ml 0.9 % saline solution s.c.) or treatment with 1 ml 150 mg canakinumab solution s.c. in a 1:1 manner.
Treatment groups
Trial outcomes
Primary outcomes
Change in Health related quality of life (mental health)
Health related quality of life (mental health; as assessed by the SF-36 mental health component score; MCS). The lower the score the more disability.
Change in Health related quality of life (physical health)
Health related quality of life (physical health; as assessed by the SF-36 physical component score; PCS). The lower the score the more disability.
Number of Hypoglycemic events
Hypoglycemic events defined as glucose values below 3.0 mmol/l
Secondary outcomes
Change in Postprandial Symptoms of hypoglycemia according to Edinburgh Hypoglycemia Scale (EHSS)
Postprandial Symptoms of hypoglycemia defined as acute onset of typical symptoms according to Edinburgh Hypoglycemia Scale. The EHSS is an instrument to evaluate patients' experiences of symptoms in a typical hypoglycemic episode. It comprises 11 symptoms divided into three domains-neuroglycopenic, autonomic, and malaise, which are evaluated by a 7-point Likert scale "1= Not at all, 7= Very severely". The postprandial period is defined as 3 hours following meal intake.
Change in Hypoglycemia unawareness (measured by modified Clarke Score)
The Clarke questionnaire consists of eight specific items characterizing awareness of hypoglycemia giving a total score of "0" to "7 (score ≥4 suggests inadequate hypoglycemia awareness; a score ≤2 suggests normal hypoglycemia awareness
Change in Fear of hypoglycemia (measured on a scale of 0 to 10)
The fear of hypoglycemia will be assessed by using a 10-cm long visual analogue scale graded from "0 - no fear at all" to "10 - massive fear"
Time below range (TBR; % of sensor glucose readings and time between 3.0 and 3.8 mmol/L)
Time below range (TBR; % of sensor glucose readings and time between 3.0 and 3.8 mmol/L)
