Safety and tolerability of nintedanib in patients with idiopathic pulmonary fibrosis in Brazil.
Ontology highlight
ABSTRACT: Objective
Clinical trials have shown that nintedanib 150 mg twice daily (bid) reduces disease progression in patients with idiopathic pulmonary fibrosis (IPF), with an adverse event profile that is manageable for most patients. Prior to the approval of nintedanib as a treatment for IPF in Brazil, an expanded access program (EAP) was initiated to provide early access to treatment and to evaluate the safety and tolerability of nintedanib in this patient population.Methods
Patients with a diagnosis of IPF within the previous five years, forced vital capacity (FVC) ≥ 50% predicted and diffusing capacity of the lungs for carbon monoxide (DLco) 30% to 79% predicted were eligible to participate in the EAP. Patients received nintedanib 150 mg bid open-label. Safety assessments included adverse events leading to permanent discontinuation of nintedanib and serious adverse events.Results
The EAP involved 57 patients at eight centers. Most patients were male (77.2%) and white (87.7%). At baseline, mean (SD) age was 70.7 (7.5) years and FVC was 70.7 (12.5) % predicted. Mean (SD) exposure to nintedanib was 14.4 (6.2) months; maximum exposure was 22.0 months. The most frequently reported adverse events considered by the investigator to be related to nintedanib treatment were diarrhea (45 patients, 78.9%) and nausea (25 patients, 43.9%). Adverse events led to permanent discontinuation of nintedanib in 16 patients (28.1%). Sixteen patients (28.1%) had a serious adverse event.Conclusion
In the Brazilian EAP, nintedanib had an acceptable safety and tolerability profile in patients with IPF, consistent with data from clinical trials.

Project description:Idiopathic pulmonary fibrosis (IPF) is a progressive disease characterised by dyspnea and loss of lung function.Using pooled data from the replicate, randomized, 52-week, placebo-controlled INPULSIS(®) trials, we characterized the safety and tolerability of nintedanib 150 mg twice daily in patients with IPF and described how adverse events were managed during these trials.One thousand and sixty- one patients were treated (nintedanib 638; placebo 423). Higher proportions of patients in the nintedanib group than the placebo group had ? 1 dose reduction to 100 mg bid (27.9% versus 3.8%) or treatment interruption (23.7% versus 9.9%). Adverse events led to permanent treatment discontinuation in 19.3% and 13.0% of patients in the nintedanib and placebo groups, respectively. Diarrhea was the most frequent adverse event, reported in 62.4% of patients in the nintedanib group versus 18.4% in the placebo group; however, only 4.4% of nintedanib-treated patients discontinued trial medication prematurely due to diarrhea. Monitoring of liver enzymes before and periodically during nintedanib treatment was recommended so that liver enzyme elevations could be managed through dose reduction or treatment interruption.Nintedanib had a manageable safety and tolerability profile in patients with IPF. Recommendations for adverse event management minimized permanent treatment discontinuations in the INPULSIS(®) trials.clinicaltrials.gov NCT01335464 and NCT01335477.

Project description:BACKGROUND:The two 52-week INPULSIS trials investigated nintedanib versus placebo in patients with IPF, FVC ≥50% predicted and DLco 30-79% predicted. The 24-week INSTAGE trial investigated nintedanib plus sildenafil versus nintedanib alone in patients with IPF and DLco ≤35% predicted. We used data from INPULSIS and INSTAGE to compare the effects of nintedanib in patients with IPF with less versus more severe impairment in gas exchange at baseline. METHODS:Analyses were conducted in patients treated with nintedanib alone in the INPULSIS and INSTAGE trials and in patients treated with placebo in the INPULSIS trials. Outcomes included the rate of decline in FVC over 24 weeks, the proportions of patients who had a confirmed or suspected idiopathic acute exacerbation over 24 weeks, deaths over 24 weeks, and adverse events. Analyses were descriptive. RESULTS:In total, 638 and 136 patients received nintedanib alone in the INPULSIS and INSTAGE trials, respectively, and 423 patients received placebo in the INPULSIS trials. Rates of FVC decline were - 52.3 and - 66.7 mL/24 weeks in patients treated with nintedanib alone in INPULSIS and INSTAGE, respectively, and - 102.8 mL/24 weeks in patients treated with placebo in INPULSIS. Confirmed or suspected idiopathic acute exacerbations were reported in 0.6 and 3.7% of patients treated with nintedanib alone in INPULSIS and INSTAGE, respectively, and 2.1% of patients treated with placebo in INPULSIS. Deaths occurred in 2.0, 11.0 and 1.9% of patients in these groups, respectively. Diarrhoea adverse events were reported in 52.5 and 48.5% of patients treated with nintedanib alone in INPULSIS and INSTAGE, respectively, and 16.1% of patients treated with placebo in INPULSIS. CONCLUSIONS:Based on data from the INSTAGE and INPULSIS trials, nintedanib had a similar effect on FVC decline over 24 weeks, and a similar safety and tolerability profile, in patients with IPF and more versus less severe impairment in gas exchange. These data support the use of nintedanib in patients with IPF who have advanced disease. TRIAL REGISTRATION:INPULSIS (NCT01335464 and NCT01335477); INSTAGE (NCT02802345).

Project description:BackgroundPhase 3 trials have shown that nintedanib reduces the decline in forced vital capacity (FVC) in patients with mild-to-moderate idiopathic pulmonary fibrosis (IPF) with acceptable safety profiles; however, its effects on advanced IPF are unclear. We investigated the efficacy and safety of nintedanib in patients with advanced IPF.MethodsProspective data were obtained from 108 IPF patients administered at least one dose of nintedanib. Of these patients, 47.2% had advanced IPF (FVC < 50% predicted, or diffusing capacity < 30% predicted).ResultsThe median treatment duration was 42.2 weeks. Nintedanib significantly reduced the decline rate in both FVC (- 0.55% [before] vs. -0.32% [after] predicted/month, p = 0.020) and total lung capacity (TLC) (- 0.35% vs. -0.06% predicted/month, p < 0.001) in all patients. A significant improvement in FVC decline rate after treatment was also observed in the advanced group (- 0.77% vs. -0.22% predicted/month, p = 0.003), but not in the non-advanced group (- 0.41% vs. -0.33% predicted/month, p = 0.564). Adverse events occurred in 97.2% of the cohort, including diarrhoea (50.0%) and anorexia (45.4%). Following adjustment for treatment duration, no inter-group difference in odds ratio was observed for the occurrence of adverse events. However, the advanced group showed a higher frequency of treatment interruption (68.0% vs. 40.0%), mainly as a result of disease progression (47.1% vs. 36.4%).ConclusionsThe efficacy and safety profiles of nintedanib in the advanced group were comparable to those in the non-advanced group except for a higher frequency of discontinuation, which may be due to the advanced status itself.

Project description:We assessed safety and tolerability of treatment with pirfenidone (1602-2403 mg·day-1) and nintedanib (200-300 mg·day-1) in patients with idiopathic pulmonary fibrosis (IPF).This 24-week, single-arm, open-label, phase IV study (ClinicalTrials.gov identifier NCT02598193) enrolled patients with IPF with forced vital capacity % pred ≥50% and diffusing capacity of the lung for carbon monoxide % pred ≥30%. Before initiating nintedanib, patients had received pirfenidone for ≥16 weeks and tolerated a stable dose of ≥1602 mg·day-1 for ≥28 days. The primary end-point was the proportion of patients who completed 24 weeks of combination treatment on pirfenidone (1602-2403 mg·day-1) and nintedanib (200-300 mg·day-1). Investigators recorded treatment-emergent adverse events (TEAEs), attributing them to pirfenidone, nintedanib, both or neither.89 patients were enrolled; 73 completed 24 weeks of treatment (69 meeting the primary end-point) and 16 discontinued treatment prematurely (13 due to TEAEs). 74 patients had 418 treatment-related TEAEs, of which diarrhoea, nausea and vomiting were the most common. Two patients had serious treatment-related TEAEs.Combined pirfenidone and nintedanib use for 24 weeks was tolerated by the majority of patients with IPF and associated with a similar pattern of TEAEs expected for either treatment alone. These results encourage further study of combination treatment with pirfenidone and nintedanib in patients with IPF.

Project description:BackgroundThe role of combination treatments with two antifibrotic agents, pirfenidone and nintedanib, has been not established in idiopathic pulmonary fibrosis (IPF). This study was performed to investigate the safety and tolerability of combination antifibrotic treatment in patients with IPF.MethodsWe conducted a proportional meta-analysis and searched PubMed, EMBASE, and the Cochrane Central Register for relevant clinical trials. The primary outcome was the proportion of discontinuation of combination treatment over the treatment period. We also examined the pooled proportions of serious and any adverse drug reactions (ADRs).ResultsFour clinical trials involving 191 patients were analyzed. In pooled estimates, 29% of patients discontinued treatment during the study period [95% confidence interval (CI): 17-41%, I2=65.42%]. The pooled proportions of serious and any ADRs were 10% (95% CI: 1-19%; I2=79.13%) and 82% (95% CI: 75-90%; I2=39.20%), respectively. During the follow-up period, gastrointestinal symptoms were the most frequent ADR. Acute exacerbation (AE) of IPF was reported in 7.0% of patients.ConclusionsOur findings showed relatively frequent incidence of discontinuation and ADRs for combination therapy in IPF. Further large-scale, randomized, controlled trials are needed to support our results because of the methodological limitations of the included trials and a scarcity of trials for analysis.

Project description:IntroductionNintedanib is recommended for the treatment of idiopathic pulmonary fibrosis (IPF); however, treatment discontinuation due to adverse events (AEs) is common. A large-scale post-marketing surveillance study is investigating the real-world tolerability/safety of nintedanib in Japanese patients with IPF in routine clinical practice. Here, we report a 12-month interim analysis of this study.MethodsThe study included Japanese patients with IPF who started nintedanib between 31 August 2015 and 25 December 2018. The primary outcome was the frequency of adverse drug reactions (ADRs), defined as AEs for which a causal relationship with nintedanib could not be excluded. The secondary outcome was change from baseline in forced vital capacity (FVC). Outcomes were analysed in patients who stopped ('discontinued' subgroup) and continued ('continued' subgroup) nintedanib after 12 months. A multivariate analysis was performed to determine potential risk factors for treatment discontinuation.ResultsOf 5578 patients in the safety analysis set, 2795 (50.1%) discontinued nintedanib within 12 months of treatment initiation. Overall, 3767 patients (67.5%) had ADRs, with 1356 (24.3%) discontinuing nintedanib because of an ADR. Among patients in the 'discontinued' subgroup (n = 2795), 1442 (51.6%) discontinued because of an ADR. The most common ADRs causing discontinuation within 3 and 12 months were hepatic function abnormal (n = 137/730; 18.8%) and diarrhoea (n = 190/1442; 13.2%), respectively. At 12 months, the decrease in FVC from baseline was smaller in the 'continued' versus the 'discontinued' subgroup (adjusted mean ± standard error change - 104.4 ± 10.9 ml vs. - 311.2 ± 29.2 ml). Stage III/IV IPF and FVC < 70% predicted at baseline were risk factors for early treatment discontinuation.ConclusionAbout 50% of Japanese patients with IPF discontinued nintedanib within the first year of treatment, with worse lung function being associated with an increased risk of early treatment discontinuation.Trial registrationClinicalTrials.gov: NCT02607722; European Union electronic register of Post-Authorisation Studies: EUPAS10891.

Project description:Idiopathic pulmonary fibrosis (IPF) is a rare lung disease characterised by progressive loss of lung function, dyspnoea and cough. IPF has a variable clinical course but a poor prognosis. Nintedanib, a tyrosine kinase inhibitor, is one of two drugs approved for the treatment of IPF. In clinical trials, nintedanib slowed disease progression by reducing the rate of decline in forced vital capacity (FVC) in patients with IPF and mild or moderate lung function impairment. The effect of nintedanib was consistent across patient subgroups defined by baseline characteristics including FVC % predicted, diffusion capacity of the lung for carbon monoxide % predicted and the presence of emphysema. Recently, it has been shown that the rate of decline in FVC and the treatment effect of nintedanib are the same in patients with preserved lung volume (FVC >90% predicted) as in patients with greater impairment in FVC, supporting the value of early treatment of IPF. The adverse events most commonly associated with nintedanib, both in clinical trials and real-world clinical practice, are mild gastrointestinal events, particularly diarrhoea. Side effects are manageable in a majority of patients through symptomatic treatment, dose reductions and treatment interruptions, enabling most patients to stay on treatment in the long term.

Project description:Purpose: Pirfenidone and nintedanib are two novel antifibrotic agents licensed for the treatment IPF. Prior to being approved for use in England for patients with FVC >50% and <80%, these were made available for all IPF patients under the Mild Patient Program (MPP) and Patient In Need Scheme (PIN). Prescribing of these medications is restricted to specialist centers. We sought to characterize the population of patients prescribed antifibrotics and determine the drug tolerability of these medications in the Northern hub of the Southwest of England regional ILD network. Methods: A retrospective analysis of all patients treated with antifibrotics between August 2012 and July 2017 was undertaken. Baseline characteristics including patient demographics and pulmonary physiology, in addition to drug tolerability and reasons for treatment cessation were collated. Data were compared using unpaired student's t-test, Chi-squared, Mann-Whitney rank sum or ANOVA as appropriate. Logistic regression analysis evaluated clinical characteristics associated with discontinuation of pirfenidone therapy. P < 0.05 was considered statistically significant. Findings: A total of 164 patients, all with consensus diagnoses of IPF, were identified. Of these, 70.1% (115/164) received pirfenidone as their initial therapy. Baseline age, gender and pulmonary physiology did not differ significantly between groups. Drug discontinuation occurred most commonly due to adverse drug reactions events (ADRs) for both pirfenidone [40.0% (46/115)] and nintedanib [16.3% (8/49)]. Anorexia, rash and gastrointestinal disturbance were reported most commonly as the reason for cessation of pirfenidone; anorexia, nausea and weight loss for nintedanib. Duration of therapy prior to discontinuation because of ADRs did not differ significantly between medication groups but patients with a baseline FVC < 65% predicted, had a significantly shorter duration of pirfenidone prior to discontinuation due to ADRs, compared to those with a FVC 65-80% predicted. Multivariate logistic regression did not identify any independent baseline characteristics that predicted discontinuation of pirfenidone therapy prior to 52 weeks. Implications: Idiopathic pulmonary fibrosis (IPF) patients treated with nintedanib had comparable treatment emergent adverse event (TEAE) profiles in clinical practice to those reported in clinical trials. The TEAE profile of pirfenidone was higher than clinical trial data would suggest, although comparable to real-world datasets. Further work is required to explore the possible reasons underpinning this finding, including whether this is related to population co-morbidities or center threshold. No new safety concerns were identified.

Project description:RATIONALE:There is no consensus as to when treatment for idiopathic pulmonary fibrosis (IPF) should be initiated. Some physicians prefer not to treat patients with preserved lung volume. OBJECTIVE:To investigate whether patients with IPF and preserved lung volume receive the same benefit from nintedanib as patients with more impaired lung volume. METHODS:Post hoc subgroup analyses of pooled data from the two replicate phase III INPULSIS trials by baseline FVC % predicted (?90%, >90%). RESULTS:At baseline, 274 patients had FVC >90% predicted and 787 patients had FVC ?90% predicted. In patients treated with placebo, the adjusted annual rate of decline in FVC was consistent between patients with FVC >90% predicted and FVC ?90% predicted (-224.6?mL/year and -223.6?mL/year, respectively). There was no statistically significant difference between these subgroups in the effect of nintedanib on annual rate of decline in FVC, change from baseline in St George's Respiratory Questionnaire total score or time to first acute exacerbation. In patients with baseline FVC >90% predicted and ?90% predicted, respectively, the adjusted annual rate of decline in FVC with nintedanib was -91.5?mL/year (difference vs placebo: 133.1?mL/year (95% CI 68.0 to 198.2)) and -121.5?mL/year (difference vs placebo: 102.1?mL/year (95% CI 61.9 to 142.3)). Adverse events associated with nintedanib were similar in both subgroups. CONCLUSIONS:Patients with IPF and preserved lung volume (FVC >90% predicted) have the same rate of FVC decline and receive the same benefit from nintedanib as patients with more impaired lung volume.

Project description:BackgroundIdiopathic pulmonary fibrosis (IPF) predominantly affects individuals aged > 60 years who have several comorbidities. Nintedanib is an approved treatment for IPF, which reduces the rate of decline in forced vital capacity (FVC). We assessed the efficacy and safety of nintedanib in patients with IPF who were elderly and who had multiple comorbidities.MethodsData were pooled from five clinical trials in which patients were randomised to receive nintedanib 150 mg twice daily or placebo. We assessed outcomes in subgroups by age < 75 versus ≥ 75 years, by < 5 and ≥ 5 comorbidities, and by Charlson Comorbidity Index (CCI) ≤ 3 and > 3 at baseline.ResultsThe data set comprised 1690 patients. Nintedanib reduced the rate of decline in FVC (mL/year) over 52 weeks versus placebo in patients aged ≥ 75 years (difference: 105.3 [95% CI 39.3, 171.2]) (n = 326) and < 75 years (difference 125.2 [90.1, 160.4]) (n = 1364) (p = 0.60 for treatment-by-time-by-subgroup interaction), in patients with < 5 comorbidities (difference: 107.9 [95% CI 65.0, 150.9]) (n = 843) and ≥ 5 comorbidities (difference 139.3 [93.8, 184.8]) (n = 847) (p = 0.41 for treatment-by-time-by-subgroup interaction) and in patients with CCI score ≤ 3 (difference: 106.4 [95% CI 70.4, 142.4]) (n = 1330) and CCI score > 3 (difference: 129.5 [57.6, 201.4]) (n = 360) (p = 0.57 for treatment-by-time-by-subgroup interaction). The adverse event profile of nintedanib was generally similar across subgroups. The proportion of patients with adverse events leading to treatment discontinuation was greater in patients aged ≥ 75 years than < 75 years in both the nintedanib (26.4% versus 16.0%) and placebo (12.2% versus 10.8%) groups. Similarly the proportion of patients with adverse events leading to treatment discontinuation was greater in patients with ≥ 5 than < 5 comorbidities (nintedanib: 20.5% versus 15.7%; placebo: 12.1% versus 10.0%).ConclusionsOur findings suggest that the effect of nintedanib on reducing the rate of FVC decline is consistent across subgroups based on age and comorbidity burden. Proactive management of adverse events is important to reduce the impact of adverse events and help patients remain on therapy.Trial registrationClinicalTrials.gov NCT00514683, NCT01335464, NCT01335477, NCT02788474, NCT01979952.
