Key finding
The rate of confirmed hypoglycemic episodes was 86% higher (p < 0.0001) for IDegAsp versus IGlar.
This study compared the efficacy and safety of insulin degludec/insulin aspart with insulin glargine in insulin-naïve adults with type 2 diabetes. IDegAsp showed a significantly higher rate of hypoglycemic episodes but lower nocturnal hypoglycemia.

Study focus
This study compared the efficacy and safety of insulin degludec/insulin aspart with insulin glargine in insulin-naïve adults with type 2 diabetes. IDegAsp showed a significantly higher rate of hypoglycemic episodes but lower nocturnal hypoglycemia.
Understanding the safety profiles of insulin treatments is crucial for managing type 2 diabetes effectively. This study highlights the trade-offs between achieving glycemic control and the risk of hypoglycemia, which is a significant concern for patients and healthcare providers when choosing insulin therapy.
The study's population may not represent all insulin-naïve adults with type 2 diabetes. Potential confounding factors not measured could influence results. The trial duration may not capture long-term safety and efficacy.

Mean HbA1c decreased similarly in both IDegAsp and IGlar groups.
Mean fasting plasma glucose showed comparable reductions in both treatment groups.
The rate of confirmed hypoglycemic episodes was 86% higher for IDegAsp (p < 0.0001).
The rate of nocturnal hypoglycemia was 75% lower for IDegAsp (p < 0.0001).
