• BioInvent's pipeline expanding to four drug candidates in five clinical trials

Lund, Sweden - December 8, 2021 - BioInvent International AB ("BioInvent") (Nasdaq Stockholm: BINV), a biotech company focused on the discovery and development of novel and first-in-class immune-modulatory antibodies for cancer immunotherapy, today announces it has submitted a Clinical Trial Application (CTA) for the novel, fully human FcyRIIB-blocking antibody, BI-1607.

BI-1607 targets FcyRIIB but is modified in its Fc region to alter its affinity for Fc receptors. By selectively blocking FcyRIIB, BI-1607 enhances the activity of other therapeutic monoclonal antibodies, whose mechanism-of-action involves depletion of tumors or immune suppressive cells. Understanding the biology of FcR/Fc interactions was essential for generating BI-1607, which has a clearly differentiated profile from BioInvent's lead drug candidate BI-1206.

BioInvent intends to explore the activity of BI-1607 in advanced solid tumors and antibody combinations supported by strong preclinical data.

"We are pleased to have completed this step in the development. BI-1607 is a very promising approach given its ability to enhance anti-cancer immunity and approval of the CTA will expand the BioInvent pipeline to four drug candidates in five clinical trials, further underlining the productivity of our technology platform," said Martin Welschof, CEO of BioInvent.
