Background: Few data are available on the progression and management of ILD, or the management of adverse events associated with drug treatment, in patients with lcSSc. SENSCIS-ON is an open-label extension trial that is collecting data on decline in forced vital capacity (FVC) and adverse events in patients treated with nintedanib over the long term.

Objectives: To assess decline in FVC and adverse events in patients with lcSSc and ILD treated with nintedanib in SENSCIS-ON.

Methods: Patients with SSc-ILD were eligible to enter SENSCIS-ON if they completed the randomized placebo-controlled SENSCIS trial (in which patients received trial drug until the last patient reached week 52 but for ≤100 weeks) or a drug–drug interaction (DDI) study of nintedanib and oral contraceptive (in which female patients received nintedanib for ≤28 days). Among patients with lcSSc, we analysed changes from baseline in FVC and adverse events over 52 weeks of SENSCIS-ON in patients who received nintedanib in SENSCIS and continued it in SENSCIS-ON (“continued nintedanib” group) and in patients who received placebo in SENSCIS and initiated nintedanib in SENSCIS-ON or who received nintedanib for a short time in the DDI study (“initiated nintedanib” group). Analyses were descriptive.

Results: There were 98 patients with lcSSc in the continued nintedanib group and 127 patients with lcSSc (114 from SENSCIS, 13 from the DDI study) in the initiated nintedanib group. In these groups, respectively, mean (SD) FVC values at inclusion in SENSCIS-ON were 2449 (662) mL and 72.7(16.7) % predicted and 2508 (771) mL and 74.1 (17.4) % predicted. Mean (SE) changes in FVC from baseline to week 52 of SENSCIS-ON were −45.1 (19.1) mL in the continued nintedanib group, −41.5 (24.0) mL in the initiated nintedanib group, and −43.3 (15.3) mL in all patients with lcSSc, similar to the change in FVC in patients with lcSSc at week 52 of the SENSCIS trial (−39.1 [22.2] mL). The adverse event profile of nintedanib in SENSCIS-ON was consistent with that reported over 52 weeks of the SENSCIS trial ( Table 1 ). Over 52 weeks, adverse events led to discontinuation of nintedanib in 3.1% of patients with lcSSc who continued nintedanib in SENSCIS-ON and 16.5% who initiated nintedanib in SENSCIS-ON.

Conclusion: The change in FVC in patients with lcSSc and ILD who received nintedanib over 52 weeks, and the safety profile of nintedanib, in SENSCIS-ON were similar to that observed in patients with lcSSc and ILD who received nintedanib in SENSCIS. These analyses support a continued effect of nintedanib on slowing decline in FVC and the ability to manage adverse events of nintedanib in patients with lcSSc and ILD over the longer term.
