Gan & Lee Pharmaceuticals on the official acceptance of the biologics license application for the proposed biosimilar insulin aspart injection by the US FDA
  • In 2021, among adults aged 20-79 in the United States, the prevalence rate of diabetes (type 1 and 2 combined) was 13.6%, with 32.2 million diabetic patients – ranking fourth highest in the world1. In addition, the annual expenditure in the US related to diabetes for each patient is 11,779.2 USD, the second highest in the world1. Through a marketing application (Biologics License Application or BLA) in the United States, Gan & Lee Pharmaceuticals will further improve drug accessibility and hopes to deliver value to more patients with diabetes in the US.


  • In 2018 Gan & Lee Pharmaceuticals signed a license agreement with Sandoz for three insulin analogs, allowing Sandoz to commercialize Gan & Lee's insulin products in the licensed territories. The successful filing of Aspart insulin is another core product in the strategic collaboration, following the successful BLA acceptance by the FDA for insulin glargine and insulin lispro.


Beijing, China/Bridgewater, New Jersey US, June 14th, 2023—Gan & Lee Pharmaceuticals (hereinafter referred to as Gan & Lee, stock code: 603087.SH), is a leading biopharmaceutical enterprise in China with a history of 25 years, integrating R&D, production and commercialization of recombination human insulin and insulin analogs. Today, the company announced that the submission of BiologicsLicense Application (hereinafter referred to as "BLA") of insulin aspart injection, a proposed biosimilar drug developed by the company for the control of blood glucose in diabetic patients, has been accepted for filing by the US Food and Drug Administration (hereinafter referred to as "FDA") and entered the substantive review stage.


Before the BLA submission, a randomized, double-blind, comparative PK/PD study was completed in the US and EU, comparing the proposed biosimilar Gan & Lee Insulin Aspart Injection to the reference product Novolog®/NovoRapid®*. Based on the overall results of this trial, Gan & Lee Insulin Aspart Injection is equivalent to both US-authorized Novolog® and EU-licensed NovoRapid®. Insulin Aspart product Novolog®. In 2022, Insulin Aaspart product NovoRapid® had global sales of DKK 15.46 billion (approx. USD 2.216 billion), of which the US market had sales of DKK 5.641 billion (approx. USD 809 million)2.


Kai.Du, CEO of Gan & Lee Pharmaceuticals, said, “Insulin aspart developed by Gan & Lee Pharmaceuticals, was approved in 2020 as the first domestic insulin aspart in the Chinese market. Since then, it has received good market feedback and is being recognized and chosen by more doctors and patients. We expect that the three insulin products recently submitted in the US will contribute to the improvement of insulin accessibility worldwide and bring benefits to more 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 Aspart

Insulin aspart is a rapid-acting insulin analog, which is modified to provide blood insulin within 10 to 20 minutes after subcutaneous injection. The maximum glucose-lowering effect of Insulin aspart occurrs between 1 and 3 hours after injection, and the effect of insulin aspart can last 3 to 5 hours. It can effectively control postprandial blood sugar. Insulin aspart should be injected before a meal or, if necessary, immediately after a meal. Insulin aspart shows the characteristics of rapid-action, short duration of action, and low risk of nocturnal hypoglycemia. It is usually used in regimen with long-acting insulin to achieve both basal and postprandial blood glucose control in patients with diabetes.


Cooperation with Sandoz AG

In 2018, Gan & Lee Pharmaceuticals signed a commercialization and supply agreement with Sandoz, a division of the international pharmaceutical company Novartis. 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.
