Nintedanib is approved for the treatment of idiopathic pulmonary fibrosis (IPF) and was demonstrated to slow disease progression in patients with IPF by reducing decline in forced vital capacity by 50%. Recently, nintedanib has been reported to exert anti-fibrotic activity on systemic sclerosis (scleroderma, SSc) skin fibroblasts and to diminish skin and lung fibrosis in mouse models. The goal of the present study was to determine the effects of nintedanib on a cellular model of SSc-associated interstitial lung disease (ILD). ⋯ Our data demonstrate significant antifibrotic efficacy of nintedanib in SSc-ILD LF suggesting that nintedanib has the potential not only to prevent but also to reverse the increased activity of LF consequently attenuating excessive lung fibrosis observed in SSc-ILD.
