About this study

Official title: Phase II, Multicenter, Randomized, Double-blind, Intraindividually Placebo Controlled Clinical Trial, to Evaluate Efficacy and Safety of p144 Topical Administration for Skin Fibrosis in Patients With Systemic Sclerosis

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 asses the efficacy and safety of topical application of P144 in the treatment of skin fibrosis in patients with systemic sclerosis.

Read the detailed description

Systemic sclerosis or scleroderma is a multisystemic disorder characterized by the excessive synthesis and deposition of extracellular matrix proteins that result in the fibrosis of skin and visceral organs (including gastrointestinal tract, lungs, heart and kidneys).

The pathogenesis of scleroderma is complex and still poorly understood, but major pathways involved in the development of the condition are microvascular and immunological abnormalities, as well as dysregulation of fibroblast activity. One of the key molecules involved in the pathogenesis of skin fibrosis is the TGF-β1; TGF-β1 is a cytokine directly responsible for fibroblasts proliferation and collagen and extracellular matrix overproduction.

The affected skin of patients with systemic sclerosis gradually becomes firm, thickened and eventually tightly bound to underlying subcutaneous tissue (indurative phase). It loses hair, oil, and sweat glands becoming dry and coarse. Changes begin distally in the extremities and advance proximally. Lesions develop over a period of time varying from months to a few years. In patients with limited scleroderma, only the skin of fingers, hands, face and lower arms and legs is affected. On the contrary, patients with the diffuse cutaneous disease, skin changes will become generalized, involving initially the extremities and followed by the face and trunk. Rapid progression of these changes over a 2 to 3 year period is usually associated with a greater risk of visceral disease. After several years of disease, the skin may soften and return to normal thickness or become thin and atrophic.

There is currently no approved specific treatment for skin fibrosis in systemic sclerosis neither in the European Union nor the United States of America. P144 belongs to a peptide family that is able to inhibit TGF-β1 in both in vitro and in vivo models characterized by excessive TGF-β1 function. Topical application of P144 exerts a preventive effect precluding the induction of skin fibrosis and the accumulation of collagen in these animals and also has shown its therapeutic properties reducing the skin fibrosis and soluble collagen content in mice with established fibrosis.

The EMEA and FDA have granted P144 the orphan drug status for the treatment of systemic sclerosis. In this study, the percentage of reduction in the soluble collagen content and skin hardness (durometer) will be measured.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 20 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 11 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 17 sites in Poland, Germany, Spain, United Kingdom, Hungary and 1 more country. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

The percentage of reduction in the soluble collagen content and skin hardness after three months relative to baseline. (time frame: Three months). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00574613, which also lists 4 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 11 Feb 2013.
