Antibody-based antiangiogenic cancer therapy.

Monoclonal antibodies are beginning to fulfil their potential as therapeutics in different pathological conditions, with a special focus on cancer. At the same time, antiangiogenic therapy has evolved into one of the most active fields in cancer research. The logical combination of both strategies has produced a growing number of antibodies aimed to interfere with tumour angiogenesis at different steps of the angiogenic process. This development has taken advantage of recombinant technologies that have revolutionised the selection and production of monoclonal antibodies, and gene therapy approaches that achieve sustained and effective concentrations of therapeutic antibodies in vivo. Here, the current knowledge about these antibody-based antiangiogenic strategies is summarised and the authors propose a novel therapeutic approach based on the blocking of crucial binding sites present in the extracellular matrix.
