A standardized core set for systemic sclerosis clinical trials. First step in development of combined response index.

Abstract

SSc can be associated with a high morbidity and mortality. Due to the complexity and heterogeneity of the disease, a composite response measure that will capture differing organ involvements and patient-reported outcomes is desirable. Recently, with participation of the Scleroderma Clinical Trial Consortium, a standardized core set of items were proposed for SSc clinical trials using a structured Delphi exercise. The Delphi exercise identified 11 domains relevant to SSc clinical trials. Currently, efforts are under way to develop a combined response index for clinical trials in diffuse cutaneous SSc.
