• Biosimilars Bysumlog^® (insulin lispro) and Dazparda^® (insulin aspart) approved for treatment of diabetes mellitus across all indications of respective reference medicines

• Potential to expand access to insulin treatment options for millions of diabetes patients in Europe

• Further strengthens Sandoz position in diabetes, following European Commission approval of Ondibta^® (insulin glargine) in January 2026

Basel, 15 May 2026 – Sandoz (SIX:SDZ/OTCQX:SDZNY), the global leader in affordable medicines, today confirms that the European Commission has granted marketing authorisation for Bysumlog (insulin lispro) and Dazparda (insulin aspart). The two biosimilar insulins, for injection in prefilled pens, are developed by Gan & Lee Pharmaceuticals.

Bysumlog is approved for the treatment and initial stabilisation of diabetes mellitus in adults and children¹, while Dazparda is approved for the treatment of diabetes mellitus in adults, adolescents and children aged one year or more². Both biosimilar insulins have equivalent efficacy and comparable safety to their respective reference medicines, Humalog^®* and NovoRapid^®**^3,4. Following these approvals, Bysumlog and Dazparda have the potential to increase competition, improve affordability and expand access to insulin treatment options for millions of people living with diabetes across Europe.

Armin Metzger, President Biosimilar Development, Manufacturing and Supply, Sandoz, said: “Diabetes and its complications can devastate the lives of patients and their families and the disease is placing growing strain on healthcare systems across Europe. As prevalence continues to rise, the need for high-quality, affordable diabetes treatments is increasingly urgent. The approvals of Bysumlog and Dazparda, alongside Ondibta earlier this year, represent a meaningful step to expand access to vital insulins and reflect our commitment to drive sustainable access to life-enhancing biosimilar medicines.”

Diabetes is a chronic condition that occurs when either the pancreas does not produce enough insulin, a hormone that regulates blood glucose, or when the body cannot effectively use the insulin it produces. The disease and its complications can cause blindness, kidney failure, heart attacks, stroke and lower-limb amputation in some patients⁵. An estimated 66 million adults aged 20–79 in Europe live with diabetes and this is projected to rise by 10% to 72 million by 2050, with related healthcare expenditure approaching USD 200 billion⁶.

Sandoz entered into an agreement with Gan & Lee in December 2018 to commercialise biosimilar versions of the insulins aspart, lispro and glargine. Under the terms of the agreement, Sandoz will commercialise in Europe and other key territories around the world, while Gan & Lee is responsible for development, manufacturing and supply.

The approvals contribute to the continued Sandoz leadership and pioneering legacy in biosimilars, dating back to the introduction of the first biosimilar in 2006. They underscore the company’s commitment to help millions of patients access biologic medicines sustainably and affordably through a global portfolio of 13 biosimilars, supported by an industry-leading pipeline. They further strengthen the Sandoz position in diabetes, while representing another step towards the overall strategic objective of capitalising on a projected ~USD 320 billion biosimilar market opportunity over the next 10 years⁷.

About Bysumlog (insulin lispro)
Insulin lispro is a rapid-acting insulin analogue which is modified to provide plasma insulin within 10 to 15 minutes after subcutaneous injection. The insulin peak concentration appears within 30 to 70 minutes after injection and the effect of insulin lispro can last two to five hours. It can effectively control postprandial blood sugar. Insulin lispro shows the characteristics of rapid action, short duration of action and lower risk of late post‑prandial and nocturnal hypoglycaemia compared with regular human insulin. It is typically used in combination with long-acting insulin to achieve both basal and postprandial blood glucose control in patients with diabetes. As a biosimilar, insulin lispro has equivalent efficacy and comparable safety to its reference medicine¹.

About Dazparda (insulin aspart)
Insulin aspart is a rapid-acting insulin analogue in which the proline at position B28 of the human insulin amino acid chain is replaced with aspartic acid, accelerating the rate of subcutaneous absorption. Following subcutaneous injection, insulin aspart has an onset of action within 10 to 20 minutes, reaches a peak effect within one to three hours post-administration, and has a duration of action of three to five hours, enabling effective control of postprandial blood glucose levels. As a biosimilar, insulin aspart has equivalent efficacy and comparable safety to its reference medicine².
