InterMune Reports Japanese Regulatory Approval of Pirfenidone in IPF
Dan Welch, Chairman, Chief Executive Officer and President of InterMune,said, "We are very encouraged by the Japanese regulatory approval ofpirfenidone for IPF, making pirfenidone the first medicine approved for IPFpatients in any major market in the world."
InterMune also provided a progress report on its Phase 3 CAPACITY programof pirfenidone in IPF. CAPACITY consists of two multinational, randomized,double-blind, placebo-controlled Phase 3 studies with a total enrollment of779 IPF patients at 110 centers in the United States, Europe and Australia.The primary endpoint in CAPACITY is change in Forced Vital Capacity (FVC) frombaseline to week 72.
InterMune reported that 97% of transplant-free, surviving patients hadcompleted their Week 72 Visit, the study visit at which the primary endpointis assessed.
The CAPACITY protocol calls for a final patient visit to be completed 30days after the Week 72 Visit. This means that all patient visits for CAPACITYare expected to be completed around the end of October 2008. Based on thistimeline for study completion, InterMune expects to announce top-line efficacyand safety results in January or February of 2009, and remains on track forsubmission of a New Drug Application (NDA) in mid-2009, pending positive datafrom CAPACITY. Pirfenidone has received Fast Track designation from the FDA,and if granted Priority Review status, InterMune could receive a six-monthreview of its NDA submission.
Mr. Welch added, "As we approach the last patient visits in our twoCAPACITY studies, we are extremely pleased with the quality of the studyconduct and to have exceeded our aggressive goal for having at least 95% oftransplant-free, surviving patients reporting for their Week 72 Visit. Welook forward to reporting top-line results of CAPACITY in January or inFebruary of 2009."
Pirfenidone has been granted Orphan Drug and Fast Track designation in theUnited States and Orphan Drug designation in Europe for the treatment of IPF.
Idiopathic pulmonary fibrosis (IPF) is a disabling and ultimately fataldisease that affects a total of approximately 200,000 people in the UnitedStates and Europe, with approximately 30,000 new cases developing in theUnited States alone, each year. There are no medicines approved by the U.S.Food and Drug Administration (FDA) or European Medicines Evaluation Agency(EMEA) for the treatment of IPF. IPF is characterized by inflammation andscarring (fibrosis) in the lungs, hindering the ability to process oxygen andcausing shortness of breath (dyspnea) and cough. IPF is a progressivedisease, meaning that over time, lung scarring and symptoms increase inseverity. The median survival time from diagnosis is two to five years.
Prior in-vitro evidence has shown that pirfenidone inhibits collagensynthesis, down-regulates profibrotic cytokines and decreases fibroblastproliferation. Data presented from one Phase 3 study and four Phase 2clinical trials in more than 400 patients suggest that pirfenidone maypositively affect lung function and disease progression in patients with IPF.In these clinical studies, pirfenidone was generally well tolerated with themost frequent side effects reported being photosensitivity rash andgastrointestinal symptoms.
InterMune is a biotechnology company focused on the research, developmentand commercialization of innovative therapies in pulmonology and hepatology.InterMune has a pipeline portfolio addressing idiopathic pulmonary fibrosis(IPF) and hepatitis C virus (HCV) infections.
