CBR96-doxorubicin immunoconjugate
Pharmaceutical compound From Wikipedia, the free encyclopedia
cBR96-doxorubicin immunoconjugate (BMS-182248/SGN-15; also known as cBR96-Dox) is an antibody-drug conjugate or (ADC) directed to the Lewis-Y antigen designed for the treatment of cancer. The payload is the chemotherapy drug doxorubicin which is connected with a hydrazone linker to cysteine residues of the Lewis-Y specific (chimeric) monoclonal antibody BR96.[1] Following internalization, the hydrazone is hydrolyzed within the acidic environment of target cell endosomes and lysosomes to release active cytotoxic drug.

Clinical Development
In clinical trials cBR96-Dox was found to be highly active in regressing large human tumor xenografts implanted in mice or rats.[2][3] Multiple tumor models including lung, breast and colon were evaluated, and cBR96-Dox was found to have broad and potent anti-tumor activity, even in doxorubicin-resistant tumors.
