John Dawson, Chief Executive Officer of Oxford BioMedica, said: "Having recently broadened our partnership with Pfizer for the 'in vitro' diagnostic use of antibodies targeting our 5T4 tumour antigen, today's collaboration with ImaginAb further emphasises the importance of 5T4 as a target for novel anti-cancer interventions. As a companion diagnostic, targeted molecular imaging has the potential to form the basis of sophisticated patient diagnosis and treatment approaches that can positively impact the economics of therapeutic development." Commenting on the collaboration, Dr Christian Behrenbruch, Chief Executive Officer of ImaginAb, said: "The 5T4 tumour antigen is an extremely promising diagnostic and therapeutic target and we are interested in 5T4 for a variety of 'in vivo' diagnostic indications in oncology. We are particularly enthusiastic about this target for imaging ovarian cancer as the diagnosis and staging of this tragic disease is still inadequately managed with existing clinical imaging techniques and represents a major unmet medical need."
