Long-term safety and tolerability of nintedanib in patients with idiopathic pulmonary fibrosis: results from the open-label extension study, INPULSIS-ON

This study is registered with ClinicalTrials.gov, number NCT01619085, and with EudraCT, number 2011-002766-21.FindingsThe first patient was enrolled into INPULSIS-ON in July 2, 2012. Of 807 patients who completed the INPULSIS trials, 734 (91%) were treated in INPULSIS-ON. 430 (59%) patients had received nintedanib in INPULSIS and continued nintedanib in INPULSIS-ON, and 304 (41%) had received placebo in INPULSIS and initiated nintedanib in INPULSIS-ON. Median exposure time for patients treated with nintedanib in both the INPULSIS and INPULSIS-ON trials was 44·7 months (range 11·9–68·3). The safety profile of nintedanib in INPULSIS-ON was consistent with that observed in INPULSIS. Diarrhoea was the most frequent adverse event in INPULSIS-ON (60·1 events per 100 patient exposure-years in patients who continued nintedanib, 71·2 events per 100 patient exposure-years in patients who initiated nintedanib). 20 (5%) of 430 patients who continued nintedanib and 31 (10%) of 304 patients who initiated nintedanib permanently discontinued nintedanib because of diarrhoea. The adverse event that most frequently led to permanent discontinuation of nintedanib was progression of idiopathic pulmonary fibrosis (51 [12%] patients continuing nintedanib and 43 [14%] patients initiating nintedanib). The event rate of bleeding was 8·4 events per 100 patient exposure-years in patients who continued nintedanib and 6·7 events per 100 patient exposure-years in patients who initiated nintedanib. ...
