Antengene’s Manufacturing Center in Shaoxing

A model manufacturing center built with high standard

Antengene's manufacturing center in Shaoxing has 16,300 square meters in space. To date,the company has finished renovating the plant building for the production line of solid dose formulation,installed supporting facilities and packaging line for the GMP manufacturing of solid dose formulation,and set up a quality control laboratory for raw materials and finished products. Further completing the supporting facilities at the site,a GMP-compliant storage facility (including cool storage,ambient warehouse,and Grade D sampling room) was also set up at the manufacturing center. Antengene plans to start the installation and validation of the product line of oral medicines sometime this year.

Since commencing the stage one construction of the manufacturing center in June 2020,Antengene has carefully planned production and storage spaces at the manufacturing center,while maintaining a rigorous quality standard and its commitment to patients. During the project,Antengene collaborated with several leading construction and design companies in China to establish an advanced scientific quality assurance system for the construction. All contractors were chosen to meet the international standards to assure the quality construction of the manufacturing center.

Innovating to serve patients

As a leader in the development of innovative cancer therapies,Antengene is dedicated to the discovering,developing and commercializing global first-in-class and/or best-in-class therapeutics. Taking a combinatory and complementary approach to its R&D,Antengene has developed a highly differentiated pipeline of 12 candidate drugs with potential for synergistic combinations.

The manufacturing center is situated in the Binhai New Area of Shaoxing,Zhejiang province,a hot spot for the commercialization of advanced technologies in the Yangtze Delta region. The Binhai New Area is building a cluster of high-tech industries by leveraging its access to emerging technologies and talent pool of the Shanghai International Center for Technological Innovations,an effort that has attracted many leading biopharmaceutical and biotechnology companies to establish their presence in the Binhai New Area. Thanks to the supporting policies and technical resources offered by the Binhai New Area,Antengene has completed the construction and renovation of the manufacturing center within a year,enabling its vertical integration of capabilities covering discovery,and commercialization. The manufacturing center in Shaoxing will be the site for the commercial manufacturing and packaging of selinexor and other oral medicines. As a novel therapy targeting a broad spectrum of tumor types,selinexor has demonstrated antitumor activity in multiple hematologic malignancies and solid tumors,and is already approved in the U.S. for the treatment of multiple myeloma and diffuse large B-cell lymphoma. Antengene has submitted new drug applications (NDAs) for selinexor in China and multiple APAC markets,and expects to receive market authorizations during Q4 2021 and Q1 2022.

Propelled by the supporting polices of the Fourteenth Five-Year Plan,Antengene has achieved substantial growth demonstrating the value of its vertically integrated capabilities. Moving forward,Antengene will continue to leverage the resources and innovation ecosystem provided by the government while pursuing rigorous research and relentless innovation in the discovery and development of its products,to make its contribution to the drug discovery and development of a modern biopharmaceutical ecosystem in China.
