Description

Inclusion Criteria:

  1. Male or female 18+ years of age at the time of signed informed consent;
  2. SSc classification as defined by the 2013 American College of Rheumatology/European League Against Rheumatism criteria. Participants with diffuse, limited or sine cutaneous skin involvement are eligible
  3. Onset of SSc (defined by first non-Raynaud's symptom) 7 years or less prior to the Screening Visit;
  4. A Modified Rodnan skin score (mRSS) less than 40
  5. Presence of ILD with evidence of any fibrosis on HRCT (within 3 months or less of randomization)
  6. Presence of an FVC 45% or more predicted normal;
  7. Presence of a diffusing capacity of the lung for carbon monoxide (DLCO) 30% or more predicted normal, corrected for hemoglobin;

Other protocol and/or subprotocol inclusion criteria apply.

Exclusion Criteria:

  1. Presence of clinically significant pulmonary abnormalities inconsistent with ILD on HRCT (e.g., scarring due to previous active tuberculosis [TB], sarcoidosis, lung mass, or other findings unrelated to SSc-ILD, as determined by a local radiologist/Investigator);
  2. Presence of infected ulcers or active gangrene at the Screening Visit;
  3. History of scleroderma renal crisis within 6 months prior to the Screening Visit;
  4. Forced expiratory volume in 1 second/FVC <0.65 (pre-bronchodilator) at the Screening Visit
  5. History of stem cell transplantation, bone marrow transplantation, chimeric antigen receptor T-cell therapy, or solid organ transplantation;
  6. History of treatment with rituximab within the 6 months prior to the Screening Visit;
  7. History treatment with cell-depleting therapies other than rituximab, including, but not limited to, CAMPATH®; anti-cluster of differentiation (CD)3, anti-CD4, anti-CD5, antiCD19, and anti-CD20 agents; and investigational agents
  8. Treatment with tocilizumab, nintedanib, pirfenidone, abatacept, leflunomide, tacrolimus, tofacitinib, intravenous immunoglobulin (IVIG), or any biologic or cyclophosphamide within 3 months prior to Screening Visit
  9. History of use of any investigational medication or device for any indication within 30 days or 5 half-lives (whichever is longer) prior to Screening Visit.
  10. Presence of any of the following laboratory findings at the Screening Visit:

    • Estimated glomerular filtration rate <45 mL/min/1.73 m2, calculated using the Chronic Kidney Disease Epidemiology Collaboration equation;
    • Alanine aminotransferase or aspartate aminotransferase level > (2 x ULN);
    • Platelets <100 × 109/L (100,000/μL);
    • White blood cell count <2500/μL;
    • Neutrophil blood count <1500/μL;
    • Prothrombin time and partial thromboplastin time >1.5 × ULN, or international normalized ratio >2; or
    • Any other laboratory test result, that in the opinion of the Investigator, might place the study participant at risk for participation in the study.
  11. Presence of a clinically significant disorder that, in the opinion of the Investigator, could contraindicate the administration of study product, affect compliance, interfere with study evaluations, or confound the interpretation of study results
  12. Presence of a concomitant life-threatening disease with life expectancy <12 months based on the Investigator's assessment;
  13. Evidence of active tuberculosis (TB) or being at high risk for TB

Other protocol and/or subprotocol exclusion criteria apply.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Time Frame
The change in forced vital capacity (FVC, in mL).
Time Frame: from baseline to the end of the treatment period at Week 52
from baseline to the end of the treatment period at Week 52

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The percent change in high-resolution computed tomography (HRCT) quantitative interstitial lung disease - whole lung (QILD-WL);
Time Frame: from baseline to the end of the treatment period at Week 52
Lung involvement as measured by high-resolution computed tomography (HRCT) assessed by quantitative interstitial lung disease - whole lung (QILD-WL)
from baseline to the end of the treatment period at Week 52
The change in Functional Assessment of Chronic Illness Therapy (FACIT)-Dyspnea score.
Time Frame: from baseline to the end of the treatment period at Week 52
Dyspnea (severity and functional limitations) are measured by the Functional Assessment of Chronic Illness Therapy (FACIT) - Dyspnea score. Dyspnea score range 0-4, total score 0-30 (higher score = worse outcome).
from baseline to the end of the treatment period at Week 52
The proportion of study participants with an improvement in the revised CRISS score, in study participants with diffuse cutaneous SSc and baseline mRRS ≥10.
Time Frame: baseline, Week 52
baseline, Week 52
