Biocon Biologics Ltd., a fully integrated global biosimilars company and subsidiary of Biocon Ltd., has announced that the US Food and Drug Administration (FDA) has approved Kirsty (Insulin Aspart-xjhz), 100 units/mL as the first and only interchangeable biosimilar to NovoLog (Insulin Aspart).

KIRSTY is a rapid-acting human insulin analog indicated to improve glycemic control in adults and pediatric patients with diabetes mellitus. KIRSTY will be available as a single-patient-use prefilled pen for subcutaneous use and a multiple-dose vial for subcutaneous and intravenous use, the company said in a statement.

The FDA approval of KIRSTY expands Biocon Biologics’ biosimilar insulin portfolio, which also includes the first approved interchangeable biosimilar, Semglee (Insulin Glargine-yfgn Injection). KIRSTY has been available in Europe and Canada since 2022.

Shreehas Tambe, CEO and Managing Director, Biocon Biologics Ltd., said, “The FDA approval of Kirsty, the first and only interchangeable biosimilar rapid-acting Insulin Aspart in the US, is a significant step forward in our efforts to make insulin more accessible and affordable. It builds on the foundation we laid with Semglee, reinforcing our commitment to scientific excellence and patient-centric innovation. With Kirsty, we are expanding treatment choices for people living with diabetes and advancing our ambition to be a global leader in addressing unmet needs in diabetes care.”

There are 38.4 million people with diabetes in the United States, approximately 11.6 percent of the total population, with nearly a quarter of them being undiagnosed. An additional 97.6 million Americans have been identified as prediabetic. Sales of Insulin Aspart in the United States were approximately USD 1.9 billion in 2024, according to IQVIA.
