Inclusion criteria

\- Participants must fulfill the 2013 American College of Rheumatology (ACR) / European League Against Rheumatism (EULAR) classification criteria for Systemic Sclerosis (SSc), and additionally have the following:. i) Positive Antinuclear Antibodies (ANA) with nucleolar pattern and/or anti-Topoisomerase I (anti-Scl-70) antibodies. ii) Confirmation of Interstitial Lung Disease (ILD) on centrally read High-Resolution Computed Tomography (HRCT) with ≥ 10% total lung involvement, with at least one of the following attributed to active SSc:. A. Arthritis. B. Myositis. C. Carditis. D. Progressive skin disease. E. Elevated inflammatory markers. \- Participants must have a non-response or intolerance despite ≥ 6 months of treatment with at least one immunomodulatory drug. Non-response is defined as a patient, who in the opinion of the investigator, is not adequately controlled/treated and requires treatment escalation.

Exclusion criteria

* Participants must not have a requirement for supplemental oxygen therapy and/or Diffusing Capacity of the Lungs for Carbon Monoxide (DLCO) ≤ 40% (Hemoglobin (Hgb) corrected) at screening. * Participants must not have moderate to severe Pulmonary Arterial Hypertension (PAH) requiring PAH-specific combination treatment * Participants must not have pulmonary comorbidity including chronic obstructive pulmonary disease or asthma requiring daily oral corticosteroids, cigarette smoking (including e-cigarettes) within 3 months before screening or unwilling to avoid smoking throughout the study, and/or clinically significant abnormalities on HRCT not attributable to SSc assessed by the central reader at screening. * Participants must not have gastrointestinal (GI) dysmotility requiring Total Parenteral Nutrition (TPN). * Participants must not have current gangrene of a digit * Other protocol-defined Inclusion/
