Janurary 19, 2021 08:00 Eastern Daylight Time

January 19 2021- Alphamab Oncology (stock code: 9966.HK) announced that, the recombinant humanized PD-L1 single-domain antibody Envafolimab (Project Code: KN035) was granted priority review by the Center for Drug Evaluation (CDE) of the National Medical Products Administration (NMPA). The Envafolimab BLA is accepted for the treatment of microsatellite instability-high (MSI-H) advanced colorectal cancer, gastric cancer / mismatch repair deficient (dMMR) advanced solid tumors that have failed previous standard of care.


With the development of immunotherapy and combination therapy, many cancers are expected to become "chronic diseases" in the future, which can be controlled or even cured. The demand for less invasive application of medicine, eg. subC formulation of biologicsfor cancer patients is increasing. As the world's first subcutaneous PD-(L)1 inhibitor, Envafolimab has shown good safety and efficacy in multiple clinical trials with >1000 patient enrolled. In addition, compared with other PD-(L)1 antibodies on the market or currently under development, Envafolimab also has the advantages of stability at room temperature, small single injection volume, fast administration process, and fewer injection site restrictions. It could be an innovative treatment option for cancer patients and improve their quality of life.


Priority review is a procedure established to encourage R&D of new drugs and accelerate the review and approval of new drugs with obvious clinical value and urgent clinical needs. According to the new "Drug Registration Rules" ("DRR") (SAMR Order No.27) and Working Procedures for Priority Review and Approval of Drug Marketing Authorization (Interim) (No. 82 of 2020) implemented on July 1, and July 7, 2020, respectively, once granted Priority Review, the regulatory authority will prioritize the review process and resource for applications with expected shorter review timelines.
