Clinical Trial Summary

The purpose of this study is to assess feasibility, safety and preliminary efficacy of Extracorporeal Photopheresis in the treatment of active diffuse cutaneous systemic sclerosis (dcSSc). This pilot study will help to determine if further study (a RCT) is justified.

Clinical Trial Description

Systemic sclerosis (SSc, Scleroderma) is a multisystem autoimmune disease characterized by widespread vascular injury and progressive fibrosis of the skin and internal organs. There is no effective treatment for the majority of patients with diffuse scleroderma (diffuse cutaneous systemic sclerosis; dcSSc). Only few therapies have shown modest benefits in regard to some specific organ pathologies. In the early stage of dcSSc, it may be possible to reverse inflammation and reduce the probability of irreversible fibrosis via significant immune modulation as later, often the fibrosis doesn't improve with treatment.

This is a pilot study that will treat 15 participants with dcSSc who meet the eligibility criteria. The objective of the study is to determine if the benefit of Extracorporeal photopheresis (ECP) and safety are favorable in order to consider and help in the design of a randomized controlled trial (RCT). This is a Phase II study that is uncontrolled and patients will remain on their background immunosuppressive treatment unless if contraindicated for safety or drug interactions. The trial is powered to show a mean change in skin thickness measured with modified Rodnan skin score (mRSS) of ≥5 over one year, in an uncontrolled, unblinded study. The Health Assessment Questionnaire Disability Index (HAQ-DI), patient and physician global scores, inflammatory markers, and combined response index in SSc (CRISS) will all be exploratory outcomes. Other outcomes such as changes in cells on skin biopsies from baseline to end of the trial will be explored if the study is positive. ;
