Trial Purpose and Description

An interventional, double-blind, randomized, intracohort placebo-controlled design will be used to test safety, tolerability, pharmacokinetics, and preliminary efficacy of EHP-101 in 36 patients ≥ 18 and ≤ 74 years of age with documented dcSS. There will up a screening period of up to 28 days, 84 days treatment period, and 28 days follow-up.

Eligibility Criteria

Inclusion Criteria:

  • Documented SSc for up to 6 years from the first non-Raynaud's phenomenon with a total mRSS of ≥15;
  • No new or increased doses of immunosuppressants medications within 3 months prior to Screening;
  • Effective method of contraception for participants and their partners.

Exclusion Criteria:

  • Severe or unstable Systemic Sclerosis (SSc) or SSc with end-stage organ failure;
  • Patient with FVC <60%;
  • History of clinically significant medical condition or concurrent medical therapies that would exclude the patient, preclude participation in the clinical trial, influence response to study product, or interfere with study assessments;
  • History of gastrointestinal dysmotility requiring total parenteral nutrition or hospitalization within 6 months before Visit 1;
  • Any one of the following values for laboratory tests at screening:
    • Haemoglobin <9 g/dL;
    • Neutrophils <1.0 x 10^9/L;
    • Platelets <75 x 10^9/L;
    • Estimated creatinine clearance <50 mL/min according to the Cockcroft-Gault equation;
    • Serum transaminases >2.0 x upper normal limit;
    • Total bilirubin ≥1.5 x upper limit of normal.
