InterMune Announces Expanded Access Program for Pirfenidone to Treat Idiopathic Pulmonary Fibrosis (IPF) in the United States

BRISBANE, Calif., May 16, 2014 /PRNewswire/ -- InterMune, Inc. (NASDAQ: ITMN) today announced it will provide compassionate use of pirfenidone through a multi-center Expanded Access Program (EAP) in the United States to be conducted under InterMune's U.S. IND.  Pirfenidone is an investigational therapy in the U.S. and has not been approved by the U.S. Food and Drug Administration (FDA).

Expanded access programs provide a mechanism for early access to an investigational drug in the pre-approval period to treat patients with a serious or immediately life-threatening disease or condition that has no comparable or satisfactory alternative treatment options.

"We are pleased to offer this expanded access program for eligible patients in the U.S.," said Jonathan Leff, M.D., Executive Vice President of Research and Development, InterMune.  "This EAP provides a mechanism for eligible patients to access pirfenidone as a treatment option, following the recent successful completion of our ASCEND Phase 3 trial and prior to FDA's final decision on the approvability of pirfenidone in the United States." 

To enroll in the EAP, a patient must meet specific clinical criteria.  Eligible patients must have a clinical and radiographic diagnosis of IPF with the presence of a usual interstitial pneumonia (UIP) pattern on high-resolution computed tomography (HRCT).  Additional criteria for the EAP are listed on www.clinicaltrials.gov.  It is important to note that only a physician who is participating in the EAP can assess a potential patient for eligibility.  The EAP protocol contains provisions for stopping enrollment of patients in the EAP upon a decision by the FDA on the approvability of a pirfenidone New Drug Application (NDA).

There are currently a limited number of sites accepting patients for enrollment to the pirfenidone EAP and InterMune expects that all sites will be participating by September of 2014.  InterMune is working with the Pulmonary Fibrosis Foundation (PFF), the Coalition for Pulmonary Fibrosis (CPF) and other advocacy groups to enable patients with IPF to obtain information about the pirfenidone EAP.

About IPF
Idiopathic pulmonary fibrosis (IPF) is an irreversible and ultimately fatal disease characterized by progressive loss of lung function due to fibrosis (scarring) in the lungs, which hinders the ability of lungs to absorb oxygen.  IPF inevitably causes shortness of breath, and a deterioration in lung function and exercise tolerance.  IPF patients follow different and unpredictable clinical courses and it is not possible to predict if a patient will progress slowly or rapidly, or when the rate of decline may change.  Periods of transient clinical stability in IPF, when they occur, inevitably give way to continued disease progression.  The median survival time from diagnosis is two to five years, with a five-year survival rate of approximately 20-40 percent, which makes IPF more rapidly lethal than many malignancies, including breast, ovarian and colorectal cancers.  IPF typically occurs in patients over age 45, and tends to affect slightly more men than women.

About Pirfenidone
Pirfenidone is an orally active, anti-fibrotic agent that inhibits the synthesis of TGF-beta, a chemical mediator that controls many cell functions including proliferation and differentiation, and plays a key role in fibrosis.  Pirfenidone also inhibits the synthesis of TNF-alpha, a cytokine that is known to have an active role in inflammation.
