Russell - BITT-2

Unique Technology/Candidates

Boston Immune Technologies and Therapeutics (BITT) is developing a novel class of antagonist antibodies targeting TNF superfamily receptors for applications in oncology, inflammation, autoimmunity, and infectious disease.


Their lead candidate, BIR2101, is a monoclonal antibody that targets tumor necrosis factor receptor 2 (TNFR2). BITT's proprietary antibodies can target cancer cells and their microenvironment, shutting down specific signaling pathways.


Additionally, BITT is developing CD40 antagonists for inflammation and CD30 antagonists for oncology. Their proprietary antibody design platform allows for highly specific targeting of tumors based on unique binding modalities, offering potential benefits in terms of efficacy and reduced side effects compared to traditional treatments.
