Healthcare Industry News: INSPIRE trial
News Release - April 18, 2006
InterMune Completes Enrollment of the Phase III INSPIRE TrialTop-line Data Expected in Early 2008
Recent Publication Supports INSPIRE Hypothesis
BRISBANE, Calif., April 18 (HSMN NewsFeed) -- InterMune, Inc. (Nasdaq: ITMN ) announced today the completion on April 13 of patient enrollment in the INSPIRE trial, a pivotal Phase III clinical trial of ActimmuneŽ (interferon gamma-1b) in patients with idiopathic pulmonary fibrosis (IPF). The trial is anticipated to conclude in late 2007 and top-line data are expected in early 2008. At this time, ActimmuneŽ is not approved for the treatment of IPF.
Several peer-reviewed publications regarding ActimmuneŽ for the treatment of patients with IPF support the hypothesis upon which the INSPIRE trial was designed (King 2005(1), Zeische 2002(2) and Bajwa 2005(3)). Most recently, in the April 12, 2006 on-line issue of the European Respiratory Journal, Antoniou, et al,(4) reports data that further support this hypothesis.
"INSPIRE is an important study designed to conclusively determine the effect of ActimmuneŽ on survival in IPF patients with mild to moderate impairment in lung function," said study Co-Chair Talmadge E. King, Jr., M.D., Chief, Medical Services, San Francisco General Hospital; Constance B. Wofsy Distinguished Professor and Vice Chairman, Department of Medicine, University of California San Francisco. "The results from this trial, the largest ever enrolled in the field of IPF, are anxiously awaited by the medical community and IPF patients, as there is currently no U.S. Food and Drug Administration (FDA) approved treatment for this deadly disease."
"The completion of enrollment in INSPIRE marks an important milestone for our company, and we thank the many physicians, health care providers, and patients who made this accomplishment possible," stated Dan Welch, President and CEO of InterMune. "Our commitment to deliver innovative medicines for patients who suffer from IPF remains firm, as we continue to make solid progress on INSPIRE for ActimmuneŽ and on our Phase III program for pirfenidone, the industry's two most advanced programs in clinical development for this indication."

IPF is a disabling and ultimately fatal disease that affects approximately 83,000 people in the United States, with approximately 30,000 new cases developing each year. Those diagnosed with IPF are usually between the ages of 40 and 70, and the disease tends to affect men more than women. IPF causes inflammation and scarring (fibrosis) in the lungs, hindering a person's ability to process oxygen and causing shortness of breath (dyspnea) and cough. IPF is a progressive disease, meaning that over time, lung scarring and symptoms increase in severity. The disease is deadly, with a median survival time from diagnosis of two to five years and a five-year survival rate of approximately 20%. There are currently no drugs approved by the FDA or the European Medicines Evaluation Agency (EMEA) for the treatment of IPF.
ActimmuneŽ is a synthesized version of interferon gamma, a naturally occurring protein believed to stimulate the immune system. InterMune markets ActimmuneŽ for the treatment of two life-threatening congenital diseases: chronic granulomatous disease and severe, malignant osteopetrosis. The most common side effects are flu-like symptoms, including headache, fatigue, fever, chills, and rash. InterMune was recently granted two composition-of-matter patents related to interferon gamma-1b in the United States, extending its patent protection until 2022. Physicians and patients can obtain additional prescribing information regarding ActimmuneŽ, including the product's safety profile, by visiting www.actimmune.com.
InterMune is a biotechnology company focused on the research, development and commercialization of innovative therapies in pulmonology and hepatology. InterMune has a pipeline portfolio addressing idiopathic pulmonary fibrosis (IPF) and hepatitis C virus (HCV) infections. The pulmonology portfolio includes ActimmuneŽ (interferon gamma-1b), which is being evaluated in the INSPIRE trial, a Phase III study in patients with IPF, and pirfenidone, which is also being developed for the treatment of IPF. The hepatology portfolio includes the lead HCV protease inhibitor compound (ITMN B), a second- generation HCV protease inhibitor program, and a research program evaluating a new target in hepatology.
