BriaCell’s BriaPro develops antibodies to anti-cancer target B7-H3

BriaCell (BCTX) Therapeutics announces that BriaPro is developing novel, high affinity antibodies to B7-H3, a key player in cancer progression, using molecular modeling techniques. BriaPro has filed provisional US patent applications for the corresponding technology and plans on filing an international patent application under the Patent Cooperation Treaty. As both an immune checkpoint molecule that regulates T cell activity and a cell surface molecule expressed on many types of cancer cells, B7-H3 is a promising drug target. BriaPro plans on developing anti-B7-H3 antibodies for multiple cancer indications and plans to incorporate them into its Bria-TILsRx platform-a proprietary antibody platform designed to redirect and activate T cells within the tumor microenvironment. This platform integrates both T cell engagers, which promote T cell-mediated tumor killing, and tumor-targeted immune checkpoint modulators, which selectively block inhibitory signals on tumor infiltrating lymphocytes to enhance their anti-tumor activity.
