Summary:
Dr. Sophia Karagiannis is a translational cancer immunologist specialising in antibody therapies for melanoma, ovarian and breast carcinomas who has undertaken discovery and development of immunotherapeutics in academic and biotechnology environments. She has a track record on evaluating the tumour-targeting mechanisms of IgE antibodies and Th2 responses in cancer and has led studies on monoclonal antibodies of the IgG and IgE classes for the treatment of solid tumours since 1998. These have yielded the first IgE antibody therapeutic candidate for the treatment of cancer, presently in development for clinical trials in patients with FRα+ carcinomas by her team at Kings College London in collaboration with Cancer Research UK.

Since 2007 she heads her own King
