International audience. Two randomised trials (ASTIS, SCOT) of Autologous Hematopoietic Stem Cell Transplantation (AHSCT) versus monthly Cyclophosphamide for severe Systemic Sclerosis (SSc) patients used similar inclusion criteria, but different primary endpoints: event-free-survival (EFS) at 24 months in ASTIS versus the global rank composite score (GRCS) at 54 months in SCOT. Here we analysed the French ASTIS cohort (n = 49) outcome using the same GRCS endpoint as reported in SCOT. All patients, randomised to AHSCT (n = 26) or Cyclophosphamide (n = 23), were evaluated for the non-parametric GRCS endpoint based on: death, EFS, forced vital capacity (FVC), Health Assessment Questionnaire Disability Index (HAQ-DI) and modified Rodnan skin score (mRSS) at 60 months. Secondary endpoints were: EFS, overall survival (OS), HAQ DI and organ status. In intention-to-treat analysis, the GRCS demonstrated superiority for AHSCT (median: 9 versus −19, p = 0.018), mRSS (Δ mRSS: −16 versus −9, p = 0.02), and HAQ-DI (ΔHAQ-DI: −0.89 versus −0.2, p = 0.05) with no significant difference in OS, EFS, lung, heart and kidney function between the groups. In conclusion, this study demonstrates long term benefits of non-myeloablative AHSCT when assessed by the five longitudinal measures within GRCS affording direct primary endpoint comparison between ASTIS and SCOT.
