In Brief: Kirsty — An Insulin Aspart Interchangeable with NovoLog

The FDA has approved Kirsty (Biocon), a biosimilar to rapid-acting insulin aspart (NovoLog), for treatment of type 1 or type 2 diabetes. Kirsty is the first rapid-acting insulin to become available in the US that has received interchangeability status with NovoLog; Merilog, another insulin aspart biosimilar, was approved earlier but has not received interchangeability status with NovoLog.
