title: Preclinical and clinical studies with recombinant human basic fibroblast growth factor.
abstract: Basic fibroblast growth factor is a polypeptide belonging to a family of natural proteins also known as heparin-binding growth factors endowed with a pleiotropism of biological activities, the most striking of which are related to wound healing. Large quantities of recombinant human basic fibroblast growth factor (rh-bFGF) of a clinical grade were obtained and used to undertake preclinical and clinical studies. In vivo the wound healing effect of rh-bFGF was evaluated in experimental targets such as the cornea and the tympanic membrane, showing a significantly increased epithelial healing rate in drug-treated animals. The deposition of labeled rh-bFGF after topical applications in ocular wounding models did not result in a systemic absorption of the intact rh-bFGF molecule. The acute and the subchronic toxicity studies undertaken after iv and topical administration of a stable pharmaceutical formulation of rh-bFGF did not result in irritation, and no signs of general toxicity were observed. Altogether these data permitted us to start recently with human studies, which are still ongoing, aimed to evaluate the tolerability and the activity of rh-bFGF on tegumental targets such as the cornea and the skin.
