In the vast area of immunotherapies, the development of monoclonal antibodies as a therapeutic concept emerged as a quantum leap out of the area of traditional vaccines (Köhler and Milstein)1 in vitro selection and optimisation made it possible to elaborate a single biological molecule from the molecular plethora of an individual adaptive immune response and to utilize such a cloned antibody repeatedly in a generalized fashion whenever the therapeutic indication is given to humans.
At present, some 25 therapeutic monoclonal antibodies are currently being marketed in oncology, exceeding sales of USD20bn in 2011. A total of about 270 antibodies are currently in Phase II and III clinical development. Working on the assumption of usually lower attrition rates for antibody candidates, we expect approximately 120 of these 270 antibodies to be finally approved. This poses some key questions. What level of differentiation is required so that the coming new antibody drugs can command premium pricing when members of the founding generation become generic and inexpensive? What will global demand for antibody drugs be in view of the rising buying power in emerging pharmaceutical (‘pharmerging’) markets, but which is still not comparable with that of developed ones? What would the next quantum leaps be that might potentially push antibody technology on to a next level by disruptive innovation? Presentations given at the Phacilitate Immunotherapy Leaders’ Forum 2012 (9–11 May in Barcelona) reflected on these questions and provided some stimulating perspectives.
