NordicPRO-C3™ and NordicPRO-C6™ in Connective Tissue Disease-Associated Interstitial Lung Disease

NordicPRO-C3™ and nordicPRO-C6™ fibrogenesis biomarkers in connective tissue disease-associated interstitial lung disease: results from the phase IIb RECITAL trial
Introduction
ILD is a major cause of morbidity and mortality in connective tissue disease (CTD). Cyclophosphamide is an effective treatment for CTD-ILD, but limited by side effects. In this study, we additionally tested rituximab as an alternative in the RECITAL phase IIb trial. Both drugs improved the lung function with rituximab showing fewer adverse events (Maher, 2022.

Conclusion
The decrease in nordicPRO-C3™ and nordicPRO-C6™ suggest that, besides their immunomodulatory effects, these drugs may also reduce fibrogenesis. Both biomarkers, measured at baseline and as % change from baseline, are associated with FVC response. These findings highlight nordicPRO-C3™ and nordicPRO-C6™ as promising biomarkers for progressive CTD-ILD.
