RIDGEFIELD, Conn., May 18, 2015 /PRNewswire/ -- Boehringer Ingelheim announced new data and analyses that provide further evidence to support the efficacy, safety and tolerability of OFEV® (nintedanib) capsules in patients with idiopathic pulmonary fibrosis (IPF). The findings were presented yesterday at the American Thoracic Society 2015 International Conference in Denver.
"The long-term safety studies are important because people with IPF may be on therapy for an extended period," said lead study author Luca Richeldi, M.D., Ph.D., Professor of Respiratory Medicine, Chair of Interstitial Lung Disease, University of Southampton, Honorary Consultant Physician, University Hospital Southampton. "Additionally, results from other analyses show a consistent effect in patients who had mild lung function impairment or lacked extensive lung scarring, such as honeycombing in high-resolution CT scans. These new findings underscore the need for early detection and treatment."
IPF is a rare and serious lung disease that causes permanent scarring of the lungs. It affects as many as 132,000 Americans, most commonly men over the age of 65. Early diagnosis and proper care and treatment are critical to helping people with their condition.
"Boehringer Ingelheim continues to research the safety and efficacy of OFEV to improve the understanding of IPF and the role that medicine can play in treating it," said Danny McBryan, M.D., vice president, Clinical Development and Medical Affairs, Respiratory, Boehringer Ingelheim Pharmaceuticals, Inc. "The data being presented at the American Thoracic Society International Conference provide additional insights into OFEV, including the safety and efficacy beyond 52 weeks. Data also look at the effect of OFEV treatment on patients with mild lung function impairment and characteristics consistent with early disease presentation, which is representative of those seen in clinical practice."

Research Evaluating OFEV Beyond 52 Weeks
New Data and Interim Analyses of Phase III Trials Open-Label Safety Extension
The research presentations include an interim analysis of an open-label extension of the 52-week Phase III INPULSIS® trials (NCT01619085; abstract A1020). The results showed no relevant changes in the safety and tolerability profile of OFEV 150 mg twice daily in patients taking OFEV for nearly two years on average (12 months INPULSIS® study + 11 months in open-label safety extension). The open-label extension included patients who either continued on or initiated OFEV therapy following the 52-week trial period (AE: 88.8% vs. 93.8%, respectively; SAE: 31.9% vs. 29.6%, respectively).
New Data and Analyses of Phase II Trial Extension
Researchers also presented data from an extension of the Phase II TOMORROW® trial (NCT01170065; abstract A1019). Following the placebo-controlled phase of the trial (period 1: 52 weeks), patients were given the option to enter a second phase (period 2: 24 weeks). In this extension, patients in the treatment group (OFEV 150 mg twice daily, n=48) were given the option of continuing therapy, while patients in the placebo group were given the option of initiating treatment with OFEV 50 mg once daily in a comparator group (a sub-therapeutic dose, n=54).
Overall, the extension study showed:
- The absolute change in forced vital capacity (FVC, or the amount of air that can be exhaled after maximum inhalation), a measure of IPF disease progression, was lower in the treatment group (n=36) than in the comparator group (n=44) (-3.1% vs. -6.3%).
- The incidence of acute exacerbations (a sudden and serious attack of shortness of breath) was lower in the treatment group (n=86) versus the comparator group (n=87) (3.2 vs. 13.4 events for every 100 patient-years)
- Overall, adverse event (AE) and serious adverse event (SAE) rates across periods 1 and 2 for the two groups (n=85 per group) were similar (AE: 97.6% vs. 96.5%, respectively; SAE: 35.3% vs. 37.6%, respectively).
Phase III Trials Pooled Subgroup Analyses
Researchers also presented two post-hoc subgroup analyses from pooled results of the Phase III INPULSIS® trials.
Disease Progression Based on Diagnostic Criteria
In the first post-hoc analysis (NCT01335464 and NCT01335477; abstract A1022), OFEV showed a consistent effect on annual rate of FVC decline, a measure of disease progression, whether or not patients had signs of honeycombing in a lung imaging test and/or a diagnosis confirmed by biopsy provided that they met other diagnostic imaging criteria required for trial participation. The adjusted annual rates of decline in FVC compared to placebo were as follows:
- Patients with honeycombing and/or biopsy: difference 117.0 mL/year (nintedanib (n=425) -108.7 ml/year vs. placebo (n=298) -225.7 ml/year)
- Patients with no honeycombing or biopsy: difference 98.9 mL/year (nintedanib (n=213) -122.0 ml/year vs. placebo (n=125) -221.0 ml/year)
Disease Progression in Patients with Varying Degrees of Lung Function Impairment
In the second analysis (NCT01335464 and NCT01335477; abstract A1021), OFEV showed a consistent effect on annual rate of FVC decline, a measure of disease progression, whether patients had a baseline FVC of </= 90% predicted or > 90% predicted.
- Patients with baseline FVC>90% predicted, difference: 133.1 mL/year (nintedanib (n=166) -91.5 mL/year vs. placebo (n=108) -224.6 mL/year)
- Patients with baseline FVC</=90% predicted, difference: 102.1 mL/year (nintedanib (n=472) -121.5 mL/year vs. placebo (n=315) -223.6 mL/year)
About OFEV® (nintedanib) capsules
The U.S. Food and Drug Administration (FDA) approved OFEV for the treatment of idiopathic pulmonary fibrosis (IPF) on October 15, 2014. OFEV is one of the first FDA-approved drug treatments for IPF and the only kinase inhibitor approved to treat this disease.
The approval was based on findings from the Phase II TOMORROW™ trial (NCT00514683) and the Phase III INPULSIS™ trials (INPULSIS™-1 and INPULSIS™-2; NCT01335464 and NCT01335477) which were all randomized, double-blind, placebo-controlled trials comparing OFEV 150 mg twice daily to placebo for 52 weeks. Both INPULSIS™ trials were identically designed while the TOMORROW™ study design was similar.
