N2 - AIMS: Nocturnal glucose control in people with type 1 diabetes on multiple daily injection therapy is hampered by the risk of hypoglycaemia. Insulin degludec lowers the risk of patient-reported and continuous glucose monitoring-recorded nocturnal hypoglycaemia. In a cohort of people with type 1 diabetes prone to nocturnal severe hypoglycaemia, we compared nocturnal glucose profiles by hourly plasma glucose measurements during treatment with insulin degludec and insulin glargine U100.MATERIALS AND METHODS: The HypoDeg trial is a 2-year investigator-initiated, randomised, controlled crossover trial in 149 participants randomised to treatment with insulin degludec and insulin glargine U100 for 12 months each. The 51 participants in this pre-defined sub-study stayed at least one night during each treatment arm in-hospital for plasma glucose samples. Endpoints were glucose profiles, including mean plasma glucose, glycaemic variability, and risk of hypoglycaemia.RESULTS: There were no differences between treatments regarding mean plasma glucose. We saw a flatter glucose profile during insulin degludec compared to insulin glargine U100, which had a nadir at 04:00 with a subsequent rise. During treatment with insulin degludec, the participants had a lower glycaemic variability with an estimated treatment difference of -4.3% ([95% CI: -8.1 - -0.5] p < 0.05)). Participants treated with insulin degludec were less likely to experience nocturnal hypoglycaemia below 3.0 mmol/L (hazard ratio 0.36 [95% CI: 0.17-0.73] p<0.05]).CONCLUSION: Based on nocturnal plasma glucose measurements, treatment with insulin degludec compared to insulin glargine U100 administered in the evening results in lower glycaemic variability and lower risk of nocturnal hypoglycaemia without differences in mean plasma glucose.
