Primary Outcome(s)

Timepoint(s) of evaluation of this end point: Day 360

Secondary Objective: - to evaluate the safety of itacitinib in patients with SSc
- to compare the efficacy of itacitinib versus placebo in terms of disease activity, quality of life and disability

Main Objective: The main objective of this study is to show a decrease of skin fibrosis, as evaluated by the modified Rodnan skin score, after 360 days of treatment, in patients with diffuse SSc treated with itacitinib when compared to patients treated with a placebo

Primary end point(s): The primary outcome is the change in modified Rodnan skin score at 360 days.

Secondary Outcome(s)

Secondary end point(s): Security profile:
- Proportion of patients deceased at 360 days
- Adverse events at 180 and 360 days
- Severe adverse events at 180 and 360 days.

SSc disease activity
- Change in modified Rodnan skin score at 90, 180, 270 days
- Proportion of patients with an improved modified Rodnan skin score at 90, 180, 270, 360 days
- Proportion of patients with an active disease according to the EUSTAR SSc activity score at 180 and 360 days.
- Change in the Combined Response Index in Diffuse Systemic Sclerosis (CRISS) score
- Physicians and patients visual analogue scales

Quality of life and disability
- SF-36 and EQ5D scales
- HAQ-DI scale
