HAMBURG, Germany – Monoclonal antibodies and their various derivatives now represent the biotechnology industry's dominant, incumbent technology. Six of the top 10 best-selling drugs are antibodies. Two more top 10 drugs are biologics based on fusion protein designs. In all, there are around a hundred antibodies on the market. Whether cell and gene therapy (CAGT) will ever attain that level of success was the subject of two lively panel discussions – on deal trends and valuation and on collaboration and integrated development of advanced therapies – which closed the 25th anniversary edition of BIO-Europe Wednesday.
