Efficacy and Safety of JAK Inhibitors in Systemic Sclerosis-associated Interstitial Lung Disease

Withdrawn

• Conditions: Interstitial Lung Disease; Systemic Sclerosis

• Registration Number: NCT05177471
• Lead Sponsor: Central Hospital, Nancy, France

Brief Summary

Systemic sclerosis (SSc) is a heterogeneous systemic autoimmune disease with distinct prognosis according to patients. In patients with systemic sclerosis, interstitial lung disease (ILD) concerns almost 50 % of patients and represents the main cause of mortality.

Janus kinases (JAK) inhibitors are recent therapies in the field of systemic autoimmune diseases, already approved in patients with rheumatoid arthritis.

Use of JAK inhibitors in systemic sclerosis is based on their anti-inflammatory and anti-fibrotic properties. Several preclinical murine models of systemic sclerosis demonstrated the efficacy of ruxolitinib and tofacitinib on cutaneous and pulmonary fibrosis. Recently, tofacitinib was evaluated in SSc patients in two clinical studies and showed significant improvement on skin fibrosis.

The objective of this study is to evaluate efficacy and safety of JAK inhibitors in SSc patients with ILD.
