RIDGEFIELD, Conn., Sept. 29, 2015 /PRNewswire/ -- An interim analysis of the INPULSIS™-ON open-label extension trial of OFEV® (nintedanib) shows efficacy and safety that is consistent to that in the two identically-designed Phase III INPULSIS™ trials in patients with idiopathic pulmonary fibrosis (IPF). The results show no relevant changes in the safety and tolerability of OFEV. The results also suggest that treatment has a long-term effect (approximately two years) on slowing disease progression across both pivotal and open-label trials (as measured by annual rate of forced vital capacity [FVC] decline). These new data are important particularly because IPF is a rare and serious lung disease, and people with IPF may be on therapy for an extended period. The results were presented at the European Respiratory Society (ERS) International Congress 2015.
The INPULSIS™-ON interim analysis showed that the decline in FVC at 48 weeks in patients continuing treatment with OFEV in the extension trial was comparable to what was observed in the 52 week INPULSIS™ trials. These data support the beneficial effect of OFEV on slowing disease progression long-term in people with IPF.
"These data are significant because they provide additional evidence that OFEV maintains its safety profile and efficacy at slowing IPF disease progression over approximately two years, reinforcing the previously-reported one-year Phase III data," said Eric White, M.D., Associate Professor of Medicine, Pulmonary and Critical Care, University of Michigan Health System. "Studies like INPULSIS™-ON are important because they inform us about the longer-term safety and efficacy of OFEV. IPF is a chronic disease that oftentimes requires long-term treatment. Evidence that OFEV maintains its clinical effect in the absence of any new safety signals provides me with more information to discuss with my patients considering treatment with OFEV."
Key results from the interim analysis of INPULSIS™-ON
INPULSIS™-ON (NCT01619085; abstract OA4495) is an open-label, single arm extension study. More than 90 percent of IPF patients participating in the identically-designed INPULSIS™-1 and INPULSIS™-2 trials and eligible for open-label treatment with OFEV in INPULSIS™-ON opted to participate. Patients with IPF on placebo in the INPULSIS™ trials (NCT01335464 and NCT01335477) initiated treatment with OFEV in the extension trial (n=304) and patients already treated with OFEV (n=430) in the INPULSIS™ trials continued to receive treatment.
The effect of OFEV on the mean change from baseline in FVC at week 48 of the INPULSIS™-ON trial was comparable to the one seen at 52 weeks in the INPULSIS™ trial:
- INPULSIS™-ON: -87 mL for all patients, -96.4 mL for patients continuing treatment with OFEV in the extension trial and -73.1 mL for patients initiating treatment with OFEV
- INPULSIS™ (pooled data from INPULSIS™-1 and -2): -88.9 mL (OFEV) vs. -203.0 mL (placebo)
The analysis demonstrates the effect of OFEV on slowing disease progression and provides insight into the long-term efficacy of OFEV.
No new safety signals were identified following long-term treatment with OFEV in INPULSIS™-ON. Adverse events (AEs) were reported in 92.8 percent and 96.7 percent of patients continuing with OFEV and initiating OFEV, respectively. Serious adverse events (SAEs) were reported in 41.9 percent and 39.5 percent of these same patients. The most frequent AEs were gastrointestinal in nature with diarrhea affecting 64 percent of patients and leading to drug discontinuation in 5 percent (2.3 percent and 9.5 percent of patients continuing or initiating therapy, respectively).
"These long-term data provide evidence that the effect of OFEV persists for close to two years," said Danny McBryan, M.D., vice president, Clinical Development and Medical Affairs, Respiratory, Boehringer Ingelheim Pharmaceuticals, Inc. "At Boehringer Ingelheim, we are committed to advancing the science of this devastating disease through our robust clinical trial program and ongoing research of OFEV in IPF patients. This continued research, and the inclusion of OFEV in the international IPF treatment guidelines, demonstrate the value of OFEV in providing important patient outcomes, particularly in slowing disease progression in IPF."
Consistent effect of OFEV in analyses of treatment interactions
New pooled subgroup analyses from the Phase III INPULSIS™ studies presented at the conference examined whether OFEV had a consistent effect on patients with IPF who were also taking commonly used medications, including anti-acids (abstract OA4502) and corticosteroids (abstract OA4498), when they were enrolled in the study.
Anti-acid medications are often given to patients with IPF to manage gastroesophageal reflux disease (GERD), which is common in patients with IPF and is considered to be a risk factor for IPF disease progression. IPF patients are also sometimes treated with corticosteroid medications (e.g., prednisone) and therefore those receiving low doses of corticosteroids were allowed in the INPULSIS™ trials.

About Idiopathic Pulmonary Fibrosis (IPF)
IPF is a rare and serious lung disease that causes permanent scarring of the lungs. It affects as many as 132,000 Americans, typically men over the age of 65. Early diagnosis and proper care are critical to helping people treat their condition.
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 a robust clinical trial program involving more than 1,200 patients with IPF worldwide, and included the Phase II TOMORROW™ trial (NCT00514683) and the Phase III INPULSIS™ trials (INPULSIS™-1 and INPULSIS™-2; NCT01335464 and NCT01335477). All these studies were 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.
