  • Title: An update on angiogenesis therapy.
    Author: Davda J, Labhasetwar V.
    Journal: Crit Rev Eukaryot Gene Expr; 2001; 11(1-3):1-21. PubMed ID: 11693956.
    Abstract:
    Angiogenesis is a novel approach for the therapy of various ischemia-related pathophysiologic conditions. Proangiogenic growth factors have shown promising results in preclinical studies using protein- and gene-based therapies. However, their success in clinical trials is hindered by the lack of an optimal delivery strategy that would provide sustained and localized levels of the growth factors in the diseased tissue. Targeted delivery of proangiogenic agents is expected to demonstrate therapeutic efficacy of growth factors at relatively lower doses, without the risk of systemic toxicity in terms of unwanted angiogenesis. To achieve the above objectives, various drug delivery systems are under investigation. This review describes the basic mechanism of action of growth factors, their current status in preclinical and clinical studies, and the issue of drug delivery.
