Open Label Extension (OLE) for the Patients Treated in the ISD002-P144-07 Study

Summary

Transforming growth factor-beta 1 is consistently over expressed in most fibrotic diseases and displays a variety of profibrotic effects in fibroblasts(25, 26). Activation of TGF-beta 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-beta 1 i 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-beta1 mRNA and protein levels has been described in these processes. Peptide 144 (P144)is a acetic salt of a 14mer peptide from human TGF-beta1 type III receptor (betaglycan). P144 TGF-beta1-inhibitor has been specifically designed to block the interaction between TGF-beta1 and TGF-beta1 type III receptor, thus blocking its biological effects. P144 has shown significant antifibrotic activity in mice receiving repeated sucutaneous injections of bleomycin, a widely accepted animal model of human scleroderma, and could contribute to the development. The aim of the study is to asses the long-term safety of topical application of P144 cream in the treatment of skin fibrosis in patients with systemic sclerosis in an extension open-label treatment period of 6 additional months.
