Clinical efforts to modulate angiogenesis in the adult: gene therapy versus conventional approaches.
A gene therapy approach towards the modulation of neovascularization provides important advantages that could be crucial for the success of therapies that target blood vessels. These advantages include sustained local expression and the ability to supply multiple pro- or anti-angiogenic factors. There is potential near-term success in the application of this approach for the treatment of ischemic vascular diseases. Although there is convincing proof of concept in animal models that an anti-angiogenesis gene therapy approach can be used to treat cancer, this is a highly competitive field with small molecules, recombinant proteins and monoclonal antibodies already in clinical trials. The scientific rationale for the use of gene therapy is sound, but realization of its full potential for the treatment of a broad array of diseases will require several challenging technical hurdles to be overcome and safety concerns to be alleviated.
