-- InterMune expresses confidence in ASCEND Phase 3 study outcome; updates timeline --



-- Company to conduct conference call and webcast at 4:30 p.m. EDT today --





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 CTto 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 arecommendation 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 patientswho 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.

I have been wondering for some time if it might be in InterMune's best interest to have the results of ASCEND delayed. Germany will have yet another review some time (don't recall but it may be considerable I think it may be close to a year) after they hit 50 (or is it 60?) million euro in sales. At that time any new data would be included in the review including ASCEND (if the results would be available). A cautious person by no means would assume positive results so not having negative results in hand may be best for the company. So to me I actually view a delay in enrolling patients as a POSITIVE and not a negative at all!

On a related note I would like to see the company derisk the impact of ASCEND. I can think of a few ways to do that (some I posted here investorshub.advfn.com  ) but I certainly don't have the expertise or inside knowledge the company has. Overall I think Dan Welch has done a good job with the hand he has been dealt and I am cautiously optimistic he will do that and now we have a bit less than 2 years to do that. Of course having EU sales ramp fast would remove a lot of risk :-).

On the InterMune call to me the begin negatives were the delay in launch not only for France but also Italy and Spain to likely Q4 because of price negotiations. The other negative was the problem with Pirfenidone generics being made available in some Latin American countries based on where InterMune was trying to enroll patients ( ascendtrial.com  ) and their history in the drug industry Brazil would seem to be the likely country in question. I am not concerned as much the impact it having on enrollment in ASCEND but on (potential) future sales into North America in particular. I still think the delay in enrollment may work out to InterMune's benefit in terms of reimbursement price reassement for Germany and by management comments I think they are in no hurry to rush enrollment I think this may be an unspoken reason.

In the FWIW column:

I like the recent action in the ITMN stock since the latest downgrade. My basis is about $12.50 overall.

No doubt a second approved drug for IPF would hurt ITMN stock. I've heard Dr. Paul Noble (and others) speculate and I tend to agree that the disease is likely going to require a cocktail of therapies. I imagine it will be similar but more so than PAH. Unless the Fibrogen drug is extremely efficacious I would think combination may be even more common in IPF given the limited benefit of any one agent and the high mortality. The other likelyhood (in my opinion) is patients try one drug keep declining docs have them try another.

InterMune still has a couple years on anyone and Phase 2/3 failures are numerous. I am more disappointed with their (extremely) slow roll out into other countries. If BI's drug didn't have a similar and much worse tox profile (GI) I would think BI could be a good company to partner (or just take out ITMN) maybe a bigger company could navigate the EU reimbursement better.

I don't know much about the Fibrogen drug's mechanism but would like to see ITMN license (or develop) other complimentary IPF drugs and would hope they are very open to testing Pirfenidone with other agents.

Below is that PR from Fibrogen. I do not disagree with you on this Peter, but I also believe that IPF has a significant variety of causes and also have the view of ghmm that a cocktail approach to treatment. We need multiple candidate treatments for the human fibroses.

Peter, do you think that there will be side effects of the CTGF mAb on chondrogenesis or osteogenesis, such as an increase in bone fractures upon longer term treatment? Knockout mice have shown such signals based on my earlier review of the literature.

FibroGen Announces Promising Preliminary Data from an Open-label Phase 2 Study to Evaluate the Safety and Efficacy of FG-3019 in Individuals with Idiopathic Pulmonary Fibrosis (IPF) and Provides Program Update

-FibroGen Expands Clinical Study Based on Preliminary Data Indicating Improvement in Lung Function and Lung Fibrosis in Patients with IPF-

San Francisco, CA - May 3, 2012
FibroGen, Inc., today announced expansion of an ongoing open-label Phase 2 study to evaluate the safety, tolerability, and efficacy of FG-3019, a human monoclonal antibody against connective tissue growth factor (CTGF), in individuals with idiopathic pulmonary fibrosis (IPF). The company’s decision to add a second, higher dose group is based on promising preliminary data from the first dose group as well as dose-escalation data from other clinical trials of FG-3019 indicating that higher doses of FG-3019 appear to be associated with a more robust biological and clinical response. FibroGen has also decided to add on another year of FG-3019 therapy for patients in the first dose group who are exhibiting stable or improved lung function in order to evaluate whether the observed maintenance of lung function continues.

IPF is a chronic, progressive, fatal lung disease for which there are no FDA-approved therapies. FG-3019 was developed to inhibit the activity of CTGF, a matricellular protein that plays a key role in fibrosis. More than a decade of research conducted by FibroGen and others has demonstrated a critical role of CTGF as a final common pathway in chronic fibrotic diseases in which persistent and excessive scarring leads to organ dysfunction and failure.

“This is the first demonstration in humans, to our knowledge, that reversal of fibrosis may be possible using a highly-targeted antifibrotic therapeutic,” said Thomas B. Neff, Chief Executive Officer of FibroGen.

A total of 54 patients having moderate to severe IPF for up to five years and aggressive disease progression have been enrolled into the first dose group in which 15 mg/kg FG-3019 is administered by intravenous infusion every 3 weeks for 45 weeks. Patients are tested every 3 months to assess changes in pulmonary function including measurement of forced vital capacity (FVC), a key indicator of both pulmonary function loss and disease-related mortality in IPF. For reference, based on placebo-treated patients in multiple recent clinical trials, patients with IPF typically experience a loss in lung function of approximately 7% predicted FVC per annum. In addition, patients are evaluated every 6 months by high resolution computed tomography (HRCT) imaging to assess structural changes in the lungs. HRCT assessments are made by pulmonary radiology experts who are using advanced digital imaging methods to quantify extent of and changes in lung fibrosis.
Combined 6-month preliminary pulmonary function and HRCT data are available for over half of the patients who remain in the study. Key preliminary findings from the first dose group include:
Disease severity at baseline, measured as the FVC percent predicted, ranged from 42.5% to 86.0%, with a median of 63%. These data suggest that patients enrolled in the FibroGen trial on average have greater disease severity than those enrolled in several recent IPF clinical trials with other experimental therapies. A substantial proportion of the patients who entered the trial with FVC percent predicted values above the median (i.e., > 63%) are experiencing stable disease or improvement in pulmonary function, as evidenced by increasing or stable FVC measurements during the study and comparable effects on FVC percent predicted values over the same period. Computer-generated HRCT data suggest that patients who entered the trial with disease severity above the median exhibit, on average, an improvement in lung fibrosis compared to baseline in two different measures of the extent of tissue scarring in the lung. Improved FVC appears to correlate with decreased fibrosis.

Pharmacokinetic modeling of clinical data available on FG-3019 from this and other studies suggests that dose increases are likely to generate a more consistent response. FibroGen and its scientific and medical advisors believe that higher doses of FG-3019 as well as extended treatment of patients considered responsive may result in even better clinical outcomes.

Based on the promising preliminary results from the first dose group, as well as data from other clinical trials suggesting that higher doses of FG-3019 are associated with better responses, FibroGen is expanding the Phase 2 IPF clinical trial in two ways. First, those patients from the initial dose group who appear stable or have improving FVC levels will be given the option to continue for another year of treatment with FG-3019. In addition, another group of patients will be enrolled for treatment at a higher dose of FG-3019 (30 mg/kg every 3 weeks) to further assess the safety, tolerability, and efficacy of FG-3019 in IPF patients. FG-3019 has been well tolerated in all clinical studies to date.

“Our decisions now to extend the current study and add a higher dose group are based on the data to date from this initial dose group suggesting that FG-3019 therapy may retard or prevent predicted declines in FVC and, in some cases, may increase lung capacity as measured by FVC,” said Mr. Neff. “These are potentially very important clinical findings and are surprising in light of disease severity of patients enrolled. We are hopeful that those who may be responding to FG-3019 in the current study will continue to maintain lung capacity and show improvements with extended time on treatment, and that the new group will benefit from a higher dose.”

About FG-3019
FG-3019 has been the subject of clinical studies involving over 200 patients to date, including a Phase 1 study of patients with IPF. FibroGen is currently conducting two other clinical studies with FG-3019 in addition to the IPF study. One is a study in Hong Kong in patients with liver fibrosis as a manifestation of hepatitis B. Reversal of liver fibrosis would prevent liver failure and reduce the risk of developing hepatocellular carcinoma. The other is a study in patients with pancreatic cancer, a disease in which extensive fibrosis associated with pancreatic tumors and metastases is thought to make this aggressive form of cancer highly resistant to chemotherapy. FG-3019 has been well tolerated in all clinical studies to date with no apparent safety signals.

About CTGF and IPF
IPF is a debilitating and life-threatening lung disease characterized by a progressive scarring of the lungs that diminishes functional lung volume and hinders oxygen uptake. The cause of IPF is not known. As scarring progresses, patients with IPF experience shortness of breath (dyspnea) and difficulty with performing routine functions, such as activities of daily living. Approximately 40,000 cases of IPF are diagnosed annually in the U.S. and Canada, where the overall prevalence is estimated to be 150,000. A similar prevalence exists for six other idiopathic interstitial lung diseases and systemic sclerosis that may benefit from antifibrotic therapy. There are no FDA-approved treatments for IPF, and approximately two-thirds of patients die within five years after diagnosis. Patients are often treated with corticosteroids and immunosuppressive agents, however, no therapies have been clinically proven to improve survival or quality of life. It is thought that stabilization or reversal of lung fibrosis could stabilize lung function and diminish the impact of this devastating disease.

The development of IPF is not completely understood but is thought to result from repetitive injury to epithelial cells that line the lungs. This initiates an abnormal wound healing process characterized by activation of cells called myofibroblasts, which produce and deposit excessive amounts of extracellular matrix (ECM). ECM deposition and tissue remodeling are key elements in the process of fibrosis that can eventually severely damage the lungs.

While different traumas and multiple biological factors can initiate the fibrotic process, CTGF is the final common element essential for chronic fibrosis.1,2 Studies have shown that CTGF causes transformation of multiple cell types into ECM-producing myofibroblasts and impairs important antifibrotic and proregenerative repair factors.3

Blockade of CTGF, in contrast, has been shown enable regenerative tissue repair:

administration of FG-3019 was reported to reverse fibrotic processes in a model of radiation-induced lung fibrosis at the 2010 annual meeting of the American Thoracic Society ;4 preventative and curative effects resulting from genetic blockade of CTGF using siRNA were reported in a model of liver fibrosis at the 2008 annual meeting of the American Association for the Study of Liver Diseases5 and in a subsequent journal article;6 and reversal of vascular remodeling using FG-3019 in a model of type 1 diabetes mellitus was reported at the 2006 annual meeting of the American Diabetes Association.7 CTGF is implicated as a pathogenic factor in IPF. In patients with IPF, CTGF levels are elevated in plasma,8 in transbronchial biopsy specimens, and in bronchoalveolar lavage fluid.9 Increased levels of CTGF have also been observed in experimental models of lung fibrosis.10 In addition, CTGF can cause susceptibility to experimentally-induced lung fibrosis in otherwise resistant mice.

Independent investigative teams have corroborated the reversal and regenerative effects of anti-CTGF therapy in two models of lung injury using anti-CTGF antibodies. In the first study mentioned above, FG-3019 reversed the process of fibrosis and improved lung function in a model of radiation-induced lung fibrosis.4 This model closely mimics progressive, radiation-induced lung damage in humans in which initial inflammatory stages are followed by extensive tissue remodeling and scar formation. In the second study, hyperoxia altered the development of neonatal rat lungs, inhibiting alveolarization and vascularization and promoting epithelial to mesenchymal transition and hyperplasia. Hyperoxia also induced cardiovascular remodeling leading to pulmonary hypertension, including increased pulmonary artery medial wall thickening and right ventricular hypertrophy. Treatment with FG-3149, an antibody similar to FG-3019, inhibited all of these pathologic changes, resulting in more normal lungs and hearts.11

About FibroGen, Inc.
FibroGen, Inc. was founded to discover and develop antifibrotic therapeutics. Using its expertise in the field of tissue fibrosis, in particular with matricellular proteins, such as connective tissue growth factor (CTGF), and matrix assembly enzymes, such as prolyl hydroxylases, FibroGen is now engaged in clinical development of anti-CTGF therapy and prolyl hydroxylase inhibitors for serious unmet medical needs. A placebo-controlled Phase 2 clinical trial of FG-3019 in Hong Kong addresses reversing advanced liver fibrosis and cirrhosis, the major consequences of chronic hepatitis B and C infections. Another Phase 2 pilot study addresses the ability of FG-3019 to prevent disease progression and reverse the consequences of tissue damage in idiopathic pulmonary fibrosis. Early results from an ongoing dose-escalation study in pancreatic cancer showed bioactivity of FG-3019, which is consistent with preclinical data implicating CTGF mechanistically in pancreatic cancer. From its large proprietary library of prolyl hydroxylase inhibitors, FibroGen is developing clinical and preclinical candidates designed to selectively activate HIF biology for the treatment of anemia and elicit a rapid, multifactorial, cytoprotective response for treating or preventing conditions resulting from acute ischemic injury and/or inflammation, including cardioprotection and inflammatory bowel disease. FibroGen also develops and produces recombinant human collagens and gelatins using proprietary production technology that permits making collagen essentially identical to the native protein. Development of medical devices, such as corneal implants fabricated with recombinant human collagen type III, is ongoing.

    Jim,

    do you think that there will be side effects of the CTGF mAb on chondrogenesis or osteogenesis, such as an increase in bone fractures upon longer term treatment? Knockout mice have shown such signals based on my earlier review of the literature.
    I think that only time will tell on a question like this. The effect seems much less in adult mice and the mAb isn't going to abrogate all CTGF action. The issue is obviously less important in fatal diseases such as IPF or pancreatic cancer, but may be more of an issue in liver fibrosis. Worst case is probably patients need to take some drug holidays.

    This issue of potential side effects came to mind when I saw the view from PK-PD modeling that higher dose could be used to display higher efficacy. I agree that in fatal diseases being treated in older adults, like IPF, this should be less of an issue.

    Speaking of Fibrogen here is a link to the changes in their Phase 2 study (just got the update on my RSS feed). I don't know when they started/will start cohort 2. I never count on the clinicaltrials.gov completion date (they have 12/2013). So assuming they wait for that to finish before pursing a Phase 3 and we're looking at several years behind ITMN.

    If it wasn't open label and the results continued to be promising maybe they'd have a shot with exceptional Phase 2 but that seems unlikely.

    EDIT forgot link
    clinicaltrials.gov
