Translational B cell and cancer immunologist with academic and biotechnology experience in the UK and USA. She heads a cancer antibody discovery team focusing on dissecting the crosstalk between human immunity and solid tumours and understanding the impact of antibody isotype on therapeutic efficacy. The Karagiannis group evaluate cancer patient-derived B cells and their expressed antibodies, antibody-engaging immune effector cells such as monocytes/macrophages and basophils, and engineering of antibodies of different isotypes, Fc-optimised antibodies and antibody-drug conjugates (ADCs). Sophia is founding member and elected Chair of the AllergoOncology Working Group in the European Academy of Allergy and Clinical Immunology, focused on the interface between Th2 immunity, allergy, IgE and cancer. Her group is the first to design and translate IgE class antibodies from concept to clinical testing and commercialisation. She is author of several patents on antibody technologies and founder of Epsilogen Ltd, the first immuno-oncology company dedicated to developing IgE-based cancer immunotherapies.
Antibody design to fine tune effector functions harbours potential to improve therapeutic effects. This talk will focus on two antibody Fc modification approaches that consider the immune composition of the tumour microenvironment: IgG Fc-engineering and generation of antibodies with IgE class Fc regions. Cancer biology and immunology guided antibody design can harness immune effector mechanisms and may hold promise for precision medicine, especially for patients with aggressive and treatment-resistant cancers.
