Oxford BioMedica plc (AIM-OXB) today announced that it has strengthened its cancer immunotherapy programme through the acquisition of rights to a novel human antibody, called OBAb2. The antibody has significantly higher specificity for tumours than many so-called tumour specific antibodies. The rights for it have been acquired from a leading research group led by Dr Hennie Hoogenboom at the University of Maastricht in the Netherlands. Oxford BioMedica is establishing a world-wide reputation for advanced gene-based immunotherapy for cancer. Its first product in this area, TroVaX(TM), has entered clinical development and will be tested in Phase I/II trials in colorectal cancer. In addition, the Company is developing gene-based antibody therapies to be used alongside the TroVaX(TM) vaccine. The OBAb2 antibody is part of the Company's armoury of engineered antibodies that are to be delivered by gene therapy. Commenting on the agreement, Alan Kingsman, CEO of Oxford BioMedica said: ' Oxford BioMedica has accumulated a powerful set of technologies that target the treatment of cancer by recruiting the immune system to destroy the tumour. There is substantial interest in these technologies from the pharmaceutical industry and I am confident OBAb2 will be a major deal-driver in the future.' Notes to Editors 1.
