PEGylated insulin Lispro (LY2605541): clinical overview of a new long-acting basal insulin analog in the treatment of Type 2 diabetes mellitus

摘要

Neutral Protamine Hagedorn insulin with an intermediate action profile has been in use for many years for the treatment of Type 1 diabetes and as an option for Type 2 diabetes. It is efficacious in reducing blood sugars, but shows substantial variability and risk of hypoglycemia. Basal insulin analogs have been developed in recent years to overcome these issues. Three basal insulin analogs are currently in the market in Europe. PEGylated insulin lispro is a new second-generation basal insulin analog which most likely will undergo review in 2016 by the US FDA and EMA in Europe for possible approval for marketing. Phase III trials are finalized, but not yet published. Phase II studies suggest antiglycemic efficacy, possible with a preferential hepato-specific action, a low rate of hypoglycemia, minor weight loss and acceptable tolerability. The benefit-risk profile needs, however, to be established.
