Reduction of PRO-C3 and PRO-C6 fibrogenesis biomarkers in connective tissue disease-associated interstitial lung disease: results from the Phase IIb RECITAL trial

Introduction

Interstitial lung disease (ILD) is a major cause of morbidity and mortality in connective tissue disease (CTD). While cyclophosphamide is often an effective treatment for CTD-ILD, its use is limited by side effects.

In this study, Rituximab was tested as an alternative in the RECITAL phase IIb trial (NTC1862926). Both drugs improved 24- and 48-week lung function with rituximab showing fewer adverse events.

Conclusion

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