Our mission is to develop innovative drugs for unmet therapeutic markets that are safe, effective, affordable, and for which we have intellectual property ownership.

The maintenance of a robust, proprietary pipeline is crucial to our business. To successfully meet this goal, Zelgen has successfully established two cutting-edge technology platforms, the R&D platform and commercialized platform, for the discovery and development of both small molecule and recombinant protein drugs. This has enabled us to build-up a strong pipeline covering treatment areas including liver cancer, non-small cell lung cancer, colorectal cancer, thyroid cancer, nasopharyngeal carcinomas, myelofibrosis, hemorrhage, and hepatobiliary diseases. Zelgen is also working together with several other Chinese pharmaceutical companies to co-develop combination treatments of targeted small molecule drugs and anti-PD-1/PD-L1 antibodies.

Zelgens programs have been funded five-times with awards from the National Major Innovation Drugs Fund, the National Innovation Fund for Small Technology Company, as well as other provincial Science and Technology Funds.
