Summary

Transforming growth factor-beta 1 (TGF-β1) is consistently over expressed in most fibrotic diseases and displays a variety of profibrotic effects in fibroblasts. Activation of TGF-β receptors induces the activation of several kinase signalling cascades leading to the phosphorylation of SMAD proteins as well as to the activation of SMAD-independent kinases that collectively activate ECM synthesis and fibroblast growth and differentiation into myofibroblasts. TGF-β1 is one of the main mediators in the fibrotic process, associated to both scarring and a long list of pathologies related to chronic inflammation and which affect all type of organs and tissues. An increase in TGF-β1 mRNA and protein levels has been described in these processes. Peptide 144 (P144) is the acetic salt of a 14mer peptide from human TGF-β1 type III receptor (betaglycan). P144 TGF-β1-inhibitor has been specifically designed to block the interaction between TGF-β1 and TGF-β1 type III receptor, thus blocking its biological effects. P144 has shown significant antifibrotic activity in mice receiving repeated subcutaneous injections of bleomycin, a widely accepted animal model of human scleroderma, and could contribute to the development. The purpose of this study is to assess the tolerability and safety of topical application of P144 in healthy volunteers.
