     BRISBANE,   Calif., April 5, 2012   /PRNewswire/ -- InterMune,   Inc. (NASDAQ: ITMN) today reported that the Transparency Commission   (CT: Commission de Transparence) of the French National Health Authority   (HAS: Haute Autorite de Sante) has issued a favorable opinion for the   reimbursement of Esbriet® (pirfenidone) by French National Health Insurance.   
      
     The CT noted that no other treatment provided evidence of a clinical   benefit in IPF and considering all available information, Esbriet was granted   an Amelioration du Service Medical Rendu (ASMR) rating of level IV.    ASMR is a rating of added clinical value in comparison with existing   therapies.  The CT focused on the risk/benefit ratio for assessing the   actual medical benefit (Service Medical Rendu  SMR), and rated it as   "Low."  Patients suffering with severe, chronic diseases in France   are typically reimbursed 100% for all services and medicines associated with   the management of their condition, regardless of SMR level other than   "Insufficient," (under a specific program for such diseases   (Affection de Longue Duree  ALD).  This program covers more than   8.3 million French citizens. 
      
     The CT has recommended that Esbriet be reimbursed as a "medicament   d'exception", which means that it will be reimbursed only for the   labeled indication, further defined by the CT as IPF patients with forced   vital capacity (FVC) > 50% and DLco > 35%.  The CT   also recommended that InterMune   collect information in the form of a patient registry regarding the use of   Esbriet in clinical practice.  InterMune   will now enter the next step in the process, which is to determine the price   and any reimbursement conditions of Esbriet in France   with the CEPS (Comite Economique des Produits de Sante).
      
     Dan Welch, Chairman, Chief   Executive Officer and President of InterMune,   said, "We are pleased to receive the CT's favorable opinion for   reimbursement of Esbriet.  In the recently more challenging market   access environment in France,   our rating of ASMR IV is a positive outcome for Esbriet.  The SMR and   ASMR ratings we secured for Esbriet allow us to advance to the next step in   the French process and we are optimistic about successfully concluding   negotiations with the CEPS and making Esbriet available to   patients in France   as soon as possible and practical thereafter."
      
     Based on information published on the HAS   website, since early 2011 the CT did not recommend reimbursement in 32% of   all its new product appraisals, compared with an historic average of 4%.
      
     ASCEND Phase 3 Trial    InterMune provided an   update on patient enrollment in the company's Phase 3 "ASCEND"   study, which is designed to confirm the efficacy and safety of pirfenidone   and to support an NDA re-submission for FDA approval of Esbriet   (pirfenidone) in the United States.  The company now expects ASCEND to   be fully enrolled around the end of 2012.  InterMune's   previous guidance was the second quarter of 2012.  
      
     Steve Porter, M.D., Ph.D.,   Chief Medical Officer for InterMune,   said, "Our primary mission for ASCEND is to deliver a   high-quality result, which we aim to achieve by concentrating on a select   number of high-quality sites.  While a number of factors have   contributed to the extended timeline, we are firmly convinced that the   trade-off between data quality and time is a very good one.  We believe   the trial design and refined entry criteria of ASCEND significantly increase   our probability of a successful outcome because they provide that patients   enrolled in the study have the characteristics that we know from our many   studies in IPF predict disease progression.  We are extremely pleased   with the continued enthusiasm of IPF physicians for ASCEND and look forward   to sharing the results at the end of the study." 
      
     InterMune noted that   it will discuss the status and projected timing for completion of the ASCEND   Phase 3 clinical trial of Esbriet during today's conference call and webcast.
      
     About Esbriet® (pirfenidone) in France
      
     Esbriet is the first-ever drug approved by the EU regulatory authorities   in adults for the treatment of mild-to-moderate idiopathic pulmonary fibrosis   (IPF).  In its assessment, the CT cited 7,700 mild-to-moderate IPF   patients in France.  The CT is the agency in France   responsible for assessing medicinal products and advising the health   authorities on whether those products provide sufficient benefit to be   covered by French National Health Insurance.   
      
     About SMR and ASMR 
      
     Under the French system, a new medicine may be granted one of four SMR   levels.  Of these, three are considered "sufficient"   for the CT to recommend favorable inclusion on the reimbursed drug   list.  The three sufficient SMR ratings are:  Important, Moderate   and Low.  Each rating is associated with different levels of   reimbursement.   
      
     The fourth SMR level, "Insufficient," is a recommendation   by the CT that is unfavorable to inclusion on the reimbursed drug list and if   assigned to an application, no ASMR rating is given by the CT.  In this   case, the manufacturer does not proceed to price negotiations with the   Pricing Committee (CEPS).   
      
     There are five levels of ASMR rating:
      
     ASMR I:          Major therapeutic   advance
      
     ASMR II:         Important improvement   as far as effectiveness and/or reduction of side effects are concerned
      
     ASMR III:        Moderate improvement as far   as effectiveness and/or reduction of side effects are concerned
      
     ASMR IV:       Minor improvement as far as   effectiveness and/or clinical or pharmacokinetics usefulness are concerned
      
     ASMR V:        Absence of improvement   but favorable opinion for registration on the reimbursed drugs list
      
     Since the beginning of 2011, with its significantly more challenging   reimbursement process, benefit ratings of new medicines have trended   significantly lower.  Based on information published on the HAS website,   since early 2011 the CT has granted an ASMR rating of IV in 23% of   applications.  A rating of V (absence of improvement) was granted in   33%, no ASMR rating was given (due to an SMR of "Insufficient") in   about 32% of applications, and only 11% of applications were granted an ASMR   rating higher than IV (I, II or III).
      
     About ALD
      
     In France,   diseases requiring a long-term, expensive treatment are defined as ALD   (Affection de Longue Duree  Long Term Diseases) and patients are fully   reimbursed by the National Social Security for all the costs related to this   disease (hospitalizations, lab tests, medicines, etc.).  More than 8   million French citizens are reimbursed under this scheme.  There are 30   broad disease categories  including cancer, several cardiovascular   diseases and others  as well as smaller diseases grouped in a separate   category.  Most orphan diseases fall into this scheme.

     About ASCEND
      
     ASCEND is a multinational, randomized,   double-blind, placebo controlled Phase 3 trial designed to evaluate the   safety and efficacy of Esbriet® (pirfenidone) in IPF patients with mild to   moderate impairment in lung function.  The primary endpoint is lung function,   as measured by change in forced vital capacity (FVC) from baseline to Week   52.  The trial will enroll a total of approximately 500 patients who   are randomly assigned 1:1 to receive oral pirfenidone (2403 mg/day) or   placebo.
      
     The primary endpoint in the ASCEND study is   change in percent predicted FVC, with the primary outcome analysis a Rank   ANCOVA at Week 52.  The magnitude of effect will be presented on a   categorical basis as the proportion of patients with decrements of less than   0% or greater than 10% at pre-specified study time points.
      
     Patient eligibility criteria for ASCEND include the following:
      
      
         Centrally confirmed diagnosis by High Resolution        Computed Tomography (HRCT) (+/- surgical lung biopsy)        
         %FVC  50% - 90%        
         %DLco  30% - 90%        
         FEV1/FVC ratio greater than 0.80        
         Time since IPF diagnosis greater than six months and        less than four years       
      
     Key secondary endpoints include change in six-minute walk test (6MWT)   distance and progression-free survival, which will be based on the earliest   of time to death, FVC decrement of 10% or greater, or decrement in 6MWT   distance of 50 meters or more. 
      
     Other secondary endpoints include all-cause mortality, evaluated both   independently as well as pooled with the previous CAPACITY data, and   on-treatment IPF-related deaths, which also will be evaluated independently   and pooled with the CAPACITY data, and dyspnea.        About Esbriet® (pirfenidone)
      
     Esbriet is an orally active drug 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.  It also inhibits   the synthesis of TNF-alpha, a cytokine that is known to have an active role   in inflammation.
      
     On February 28, 2011, the European   Commission (EC) granted marketing authorization for Esbriet in adults   for the treatment of mild to moderate IPF.  The approval authorizes   marketing of Esbriet in all 27 EU member states.  Esbriet has since been   approved for marketing in Norway   and Iceland.    Esbriet is commercially available in Germany,   Austria,   Norway,   Denmark   and Luxembourg.
      
     Since 2008, pirfenidone has been marketed in Japan   as Pirespa® by Shionogi & Co. Ltd.
      
     InterMune is   conducting a Phase 3 study, ASCEND, to pursue the registration of Esbriet for   the treatment of IPF in the   United States.
      
     About IPF
      
     Idiopathic pulmonary fibrosis (IPF) is a progressive, debilitating and   ultimately fatal disease characterized predominantly by fibrosis (scarring)   in the lungs, hindering the ability for gas exchange in the lungs.  IPF   is a progressive disease, meaning that over time, lung scarring and symptoms   increase in severity.  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 cancers, including breast,   ovarian and colorectal.  Published epidemiology studies suggest there is   a range of between 85,000 and 141,000 IPF patients in Europe,   with approximately 113,000 being the median estimate.  Patients   diagnosed with IPF are primarily between the ages of 40 and 80, with a median   age of 63 years.  The disease tends to affect slightly more men than   women.
