Abstract

Background Due to lack of adequate clinical research data, drug treatment of the rare disease systemic sclerosis (SSc) is commonly off-label. The international EC-funded research project DeSScipher (acronym for “to decipher the optimal management of systemic sclerosis”) was designed to increase the evidence-based treatment strategies for SSc patients and subsequently to improve their long-term quality-of-life.

Objectives The primary objective is to compare the outcomes of different treatments with respect to efficacy and safety of currently used off-label drugs from the early to the advanced phases of the main SSc-associated organ dysfunctions in a routine rheumatology in- and outpatient setting.

Methods Five prospective observational trials (OTs), carried out within the EULAR Scleroderma Trials and Research (EUSTAR) group, have been designed to analyze current treatment approaches of early functionally relevant manifestations such as digital ulcers (OT1) and hand arthritis (OT2) to the morbidity and mortality-driving manifestations such as interstitial lung disease (OT3), pulmonary hypertension (OT4) and severe heart disease (OT5). The study protocols are accessible at clinicaltrials.gov Identifiers NCT01836263, NCT01834157, NCT01858259, NCT01840748, NCT01829126.

Results Between April 2013 and January 2015, 1781 SSc patients have been screened at 27 contributing EUSTAR centers. 1577 (89%) patients have been enrolled into at least one of the five OTs. In particular, 1179, 127, 981, 237 and 716 patients have been enrolled into OT1-5, respectively (3240 in total; a given patient could be enrolled into multiple OTs), which represents a baseline patient recruitment rate of 79% of the target number of 4098 patients (accordingly 226%, 79%, 59%, 25% and 91% of the required number of 522, 160, 1670, 960, 786 patients for OT1-5, respectively). The completion of 1-year (OT3, OT5) and 2-year follow-up visits (OT1, OT2, OT4) are pending.

Conclusions DeSScipher is currently the largest prospective observational research project ever for SSc. While patient recruitment is still ongoing, preliminary results of the five OTs are expected in late 2015 and the final results depending on the completion of follow-up visits are expected between 2017 and 2018.
