BI-1206 - Non Hodgkins lymphoma and chronic lymphocytic leukemia
BioInvent’s lead drug candidate BI-1206 is a fully human antibody targeting CD32b, an immunosuppressive protein that is expressed in some patients with B-cell cancers. Research has shown that the expression of CD32b could lead to the development of resistance to rituximab, the current standard of care treatment of non-Hodgkin lymphoma (NHL) and chronic lymphocytic leukaemia (CLL). As a result, BI-1206 is being developed as a drug candidate in combination with rituximab, in B-cell cancers.
The first clinical study (Phase I/II) with BI-1206 is currently ongoing in patients with NHL and CLL who are resistant to rituximab. The initial safety and dose readouts from this study are expected in the first half of 2018. The study is financed and executed by Cancer Research UK (CRUK), Cancer Research Technology (CRT) and Leukaemia & Lymphoma Research (LLR).
Patent applications have been filed relating to antibodies against CD-32b in combination with other antibodies, such as rituximab for the treatment of cancer patients who are resistant or respond poorly to cancer therapies available today. Applications have been filed in nine large markets, including the US, Europe, Japan and China. Patent protection has also been applied for the treatment of cancer patients who not respond to previous antibody therapy.
