Anakinra for the Treatment of Postprandial Hypoglycemia in a Patient With Total Gastrectomy and End-Stage Renal Disease

Mean Amplitude of Sensor Glucose Excursions (MAGE) during Anakinra treatment compared to placebo, assessed using cumulative data from Continuous Glucose Monitoring System from all 48-hour treatment periods (48 hours following study-drug administration, Anakinra or Placebo).

Prevalence and severity of postprandial hypoglycaemia symptoms during Anakinra treatment compared to placebo, assessed using cumulative data from Continuous Glucose Monitoring from all 48-hour treatment periods.

Post-prandial hypoglycaemia symptoms and their severity will be evaluated by the patient using the Edinburgh Hypoglycemia Symptom Scale (EHSS) and are accompanied by a decrease in blood glucose levels within the postprandial period as evaluated through the CGMS.

The postprandial period is defined as the 3 hours following meal intake. A minimum blood glucose cut-off value is not required for symptom reporting. Each treatment period spans the 48 hours following study-drug administration (Anakinra or Placebo).

Time Below Range (TBR): The percentage and total duration of sensor glucose readings below thresholds of 3.3 mmol/L, 3.0 mmol/L, and 2.7 mmol/L during Anakinra treatment compared to placebo, assessed using cumulative data from all 48-hour treatment periods (48 hours following study-drug administration, Anakinra or Placebo).

Time in hyperglycaemia: The percentage and total duration of sensor glucose readings above 10 mmol/L during Anakinra treatment compared to Placebo, assessed using cumulative data from all 48-hour treatment periods (48 hours following study-drug administration, Anakinra or Placebo).

Pattern of Sensor Glucose: The slope of postprandial glucose measurements calculated as the maximal rate of increase and decrease of glucose levels observed over 20 minutes in the postprandial period, compared between Anakinra treatment and placebo, based on data from all 48-hour treatment periods (48 hours following study-drug administration, Anakinra or Placebo). The postprandial period is defined as the 3 hours following meal intake.

Comparison of the entire interventional period with the screening period regarding to the following parameters as defined above: Time Below Range, Time in hyperglycaemia, Pattern of Sensor Glucose, and Mean Amplitude of Glucose Excursions.

Changes following treatment with Anakinra compared to placebo during a Mixed Meal Tolerance Test in the AUC, peak and nadir values, and slopes of:

• Glucose
• Insulin
• c-peptide
• GLP-1
• Glucagon
• Cortisol

Changes following the entire interventional period in levels of fasting insulin, c-peptide, glucagon, HbA1c, IL-1Ra, IL-6, TNF-a, IL-18 and hsCRP as compared to Baseline.

Prevalence and severity of postprandial hypoglycaemia symptoms during the whole interventional period compared to the Screening period.

Post-prandial hypoglycaemia symptoms and their severity will be evaluated by the patient using the Edinburgh Hypoglycemia Symptom Scale (EHSS) and are accompanied by a decrease in blood glucose levels within the postprandial period as evaluated through the CGMS.

The postprandial period is defined as the 3 hours following meal intake. A minimum blood glucose cut-off value is not required for symptom reporting.-Each treatment period spans the 48 hours following study-drug administration (Anakinra or Placebo).

The patient will be asked to provide feedback on the treatment periods, indicating which study days he found the treatment more tolerable or beneficial. This subjective assessment will take into account factors such as comfort, side effects, and overall experience during the interventional period.

Adverse events of interest: AEs of interest include adverse events that can be expected during a treatment with Anakinra.

• Identification of hypersensitivity reaction during the Interventional period.
• Detection of any infection during the interventional period.
• Detection of Neutropenia during the interventional period, defined as absolute neutrophil count <1000/mm³.
• Detection of Thrombocytopenia during the Interventional period, defined as platelet count <100 000/mm³.

A Serious Adverse Event (SAE) is classified as any untoward medical occurrence that results in death, is life-threatening, requires in-patient hospitalization or prolongation of existing hospitalisation, results in persistent or significant disability/incapacity, or is a congenital anomaly/birth defect.
