Approximately 25% of patients with type 1 diabetes have lost the capacity to timely detect hypoglycaemia, a condition referred to as impaired awareness of hypoglycaemia (IAH) that causes a six-fold higher risk of severe, potentially hazardous, hypoglycaemia. IAH is usually the end-result of a process of habituation to recurrent hypoglycaemia that is potentially reversible. Treatment with sodium glucose cotransporter (SGLT)-2 inhibitors (SGLT-2i) 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 SGLT-2 inhibitor, dapagliflozin, added to basal-bolus insulin therapy will improve awareness of hypoglycaemia in patients with type 1 diabetes and IAH. In a randomized doubleblind placebo-controlled cross-over trial, patients will be treated for 8 weeks with dapagliflozin (or placebo), after which hypoglycemic symptoms and counterregulatory hormone responses will be examined during a hyperinsulinemic hypoglycemic glucose clamp study.

Symptom scores (autonomic, neuroglycopenic and general) measured during hyperinsulinemic hypoglycaemic glucose clamps. This questionnaire consists of 18 symptoms, which can be scored between 0 (none) to 6 (severe). Total scores range between 0 and 108, the higher the score, the more symptoms patients have during and after hypoglycemia.
Time frame: 45 minutes
