- Introduction: Hypoglycaemia is a common side effect of insulin therapy; low or high glycated haemoglobin (HbA(1c)) levels, history of hypoglycaemia or long diabetes duration are known modifiers of hypoglycaemia risk. In randomised clinical trials, lower rates of hypoglycaemia have been observed with the new-generation insulin analogue, long-acting insulin degludec, compared with other basal insulins.Methods: The ReFLeCT study was a prospective observational study over 12 months. Patient-reported diary data on hypoglycaemia were collected from patients with type 1 diabetes (T1D) or type 2 diabetes (T2D) who were switching from other basal insulins to insulin degludec (degludec) at their physician's discretion in routine clinical care. Two secondary analyses were undertaken to investigate the change in number of hypoglycaemic events: a post hoc analysis using the updated American Diabetes Association (ADA) level 1, 2 and 3 hypoglycaemia definitions, and a pre-specified analysis using patient characteristics (baseline HbA(1c), diabetes duration, and physician's rationale for initiating degludec).Results: Switching to degludec was associated with significantly fewer hypoglycaemic events for all definitions in T1D, and level 1 and 2 in T2D (too few level 3 events for statistical comparison). Moreover, patient characteristics did not influence the observed reduction in hypoglycaemia in T1D and T2D.Conclusion: These results demonstrate that switching to degludec from other basal insulins was associated with reduced rates of hypoglycaemia, irrespective of the definition used or baseline patient characteristics.Plain Language Summary: Low blood sugar levels (hypoglycaemia) are a common, and sometimes serious, side effect of treatment with insulin in people with diabetes. In the ReFleCT study, adults with type 1 (T1D) and type 2 diabetes (T2D) were asked to complete a diary for 12 months when their doctor changed their previous long-acting insulin treatment to insulin degludec (degludec). The key outcome of the study was whether the frequency of hypoglycaemia changed when a patient's insulin treatment was switched. Here, we used the diary information from the ReFLeCT study to investigate whether the change in the rate of hypoglycaemia was related to the way hypoglycaemia was defined, or to patients' characteristics at the time their insulin was switched. These characteristics included the length of time that patients had had diabetes, their blood sugar control, and their doctor's reason for changing their medication. Our findings showed that the way hypoglycaemia was defined, and patients' characteristics, did not generally influence the frequency of hypoglycaemia for patients with T1D or T2D. However, the most severe hypoglycaemia in patients with T2D occurred too infrequently to be assessed. Patients in all groups had less hypoglycaemia overall after switching compared with their previous treatment, suggesting that degludec may be a treatment option for a broad range of patients with diabetes.

- Background Therapies that could further prevent the development of heart failure (HF) and other cardiovascular and metabolic events in patients with recent myocardial infarction (MI) represent a large and unmet medical need. Methods DAPA-MI is a multicenter, parallel-group, registry-based, randomized, double-blind, placebo-controlled phase 3 trial in patients without known diabetes or established HF, presenting with MI and impaired left ventricular systolic function or Q-wave MI. The trial evaluated the effect of dapagliflozin 10 mg vs placebo, given once daily in addition to standard of care therapy, on death, hospitalization for HF (HHF), and other cardiometabolic outcomes. The primary objective of the trial was to determine, using the win-ratio method, if dapagliflozin is superior to placebo by comparing the hierarchical composite outcome of death, HHF, nonfatal MI, atrial fibrillation/flutter, new onset of type 2 diabetes mellitus, HF symptoms as measured by New York Heart Association Functional Classification at last visit, and body weight decrease >= 5% at last visit. Assuming a true win-ratio of 1.20 between dapagliflozin and placebo, 4,000 patients provide a statistical power of 80% for the test of the primary composite outcome. A registry-based randomized controlled trial framework allowed for recruitment, randomization, blinding, and pragmatic data collection of baseline demographics, medications, and clinical outcomes using existing national clinical registries (in Sweden and the UK) integrated with the trial database. Conclusions The trial explores opportunities to improve further the outcome of patients with impaired LV function after MI. The innovative trial design of DAPA-MI, incorporating national clinical registry data, has facilitated efficient patient recruitment as well as outcome ascertainment.
