Brief Summary:

Primary Objective:

To evaluate, in comparison with placebo, the efficacy of SAR156597 administered subcutaneously for 24 weeks on skin fibrosis in patients with dcSSc.

Secondary Objectives:

  • To evaluate the efficacy of SAR156597 compared to placebo on physical/functional disability in patients with dcSSc.
  • To evaluate the efficacy of SAR156597 compared to placebo on respiratory function in patients with dcSSc.
  • To evaluate the safety profile of SAR156597 compared to placebo in patients with dcSSc.
  • To evaluate the potential for immunogenicity (anti-drug antibodies [ADA] response) of SAR156597 in patients with dcSSc.
  • To evaluate the pharmacokinetics (PK) (trough plasma concentrations) of SAR156597 administered subcutaneously for 24 weeks.

Accepts Healthy Volunteers:   No

Inclusion criteria :

  • Diffuse cutaneous form of SSc according to Leroy's criteria.
  • Able and willing to sign the written informed consent form with comprehension of its contents and comply with the requirements of the study protocol.

Exclusion criteria:

  • Age <18 years of age.
  • Disease duration for >36 months from time of first non-Raynaud's phenomenon manifestation.
  • MRSS <10 or >35 at screening and baseline visits.
  • History of vasculitis, active or in remission.

  • Positive HIV serology or a known history of HIV infection, active or in remission.
  • Abnormal hepatitis B and/or hepatitis C tests indicative of active or chronic infection:
  • Abnormal Hepatitis B tests: Positive hepatitis B surface antigen (HBsAg) OR positive total hepatitis B core antibody (HBcAb) with negative hepatitis B surface antibody (HBsAb) OR positive total HBcAb with positive HBsAb and presence of hepatitis B DNA (HBV DNA).
  • Abnormal Hepatitis C tests: Positive anti-hepatitis C virus antibody (HCV Ab) and positive HCV RNA.
  • Positive or 2 confirmed indeterminate Quantiferon-TB Gold tests at screening (regardless of prior treatment status).

  • History of anaphylaxis to any biologic therapy.
  • Evidence of any clinically significant, severe or unstable, acute or chronically progressive, uncontrolled infection or medical condition (eg, cerebral, cardiac, pulmonary, renal, hepatic, gastrointestinal or neurologic other than SSc or SSc-interstitial lung disease) or previous, active or pending surgical disorder, or any condition that may affect patient safety in the judgment of the Investigator.
  • At screening, the % predicted forced vital capacity (FVC) is ≤75% AND % predicted carbon monoxide diffusing lung capacity (DLCO) after hemoglobin correction is ≤40%
