The Scientific Evaluation from EMA on Marketing Authorisation Application of Gan & Lee Insulin Glargine biosimilar starts upon the Positive Validation Letter

Insulin glargine biosimilar developed by Gan & Lee Pharmaceuticals (Basalin®) was approved in China in 2005. After nearly 20 years of long-term marketing, it has benefited many diabetes patients and established a good brand reputation.

Diabetes is a serious, chronic condition that occurs when the body cannot produce enough insulin or cannot effectively use the insulin it does produce (IDF 2021). According to the latest data from Global Picture of IDF Diabetes Atlas (10th edition, 2021), there are currently 537 million adults (20-79 years old) living with diabetes worldwide1

Beijing, China/Duesseldorf, Germany, Aug. 21st, 2023— Gan & Lee Pharmaceuticals Europe GmbH, a wholly-owned subsidiary of Gan & Lee Pharmaceuticals (hereinafter referred to as "Gan & Lee", stock code: 603087.SH) submitted the Marketing Authorization Application (hereinafter referred to as "MAA") of Insulin glargine biosimilar to the European Medicines Agency (hereinafter referred to as "EMA").  The EMA has accepted the MAA for review, and with this acceptance, the formal review process will begin.

Before the MAA submission, two randomized, multicenter, phase 3 studies were completed in the EU and US, comparing the proposed biosimilar Gan & Lee Insulin Glargine Injection to the reference product Lantus®*. The two studies were 26 weeks in duration and enrolled subjects with type 1 (n=576) and type 2 diabetes mellitus (n=567), respectively. In the studies, Gan & Lee Insulin Glargine Injection demonstrated /comparable immunogenicity, efficacy, and safety to Lantus®. So far, the main supplier of Insulin glargine injection in Europe is Sanofi. As a primary manufacturer, Sanofi's Insulin glargine product Lantus ® in 2022 sold 2,259 million euros, including 426 million euros in Europe2.

Dr. Zifei Yuan, CTO of Gan & Lee Pharmaceuticals, said, “After the three insulin products recently submitted in the US FDA, it is another exciting milestone that the MAA submission of Gan & Lee Insulin Glargine biosimilar was positively validated by EMA and entered into scientific evaluation stage. The submission and positive validation results have strengthened our confidence in entering EU market. We will continue to collaborate with our partner Sandoz to make biosimilar insulin glargine injection available to European diabetic patients.”

Diabetes mellitus

Diabetes mellitus is a chronic health condition that affects how the body turns food into energy. With diabetes, the body doesn’t make enough insulin or can’t use it as well as it should. When there isn’t enough insulin or cells stop responding to insulin, too much glucose stays in the bloodstream. Over time, that can cause serious health problems, such as heart disease, vision loss, and kidney disease3.

Insulin Glargine

Insulin glargine is a long-acting insulin analog, also referred to as basal insulin, which is modified to provide a consistent level of plasma insulin over a long duration as it is injected once a day. Due to its prolonged absorption, there is no pronounced peak concentration in plasma insulin. Thus, it has been associated with better glycemic control and has become an important part of the treatment of diabetes (Standards of Medical Care in Diabetes—2023, ADA, https://doi.org/10.2337/dc23-Srev)

Cooperation with Sandoz

In 2018, Gan & Lee Pharmaceuticals signed a commercialization and supply agreement with Sandoz. Under the terms of the agreement, Sandoz has the right to commercialize the three Gan & Lee biosimilars upon approval in specific regions, including the United States, Europe, and other key territories. Gan & Lee is responsible for development (incl. clinical research) and supply.
