BANGALORE, Dec 17 InterMune Inc's ITMN.O lung treatment received backing from the European health regulator, putting the drug on the road to potential blockbuster status and reviving takeover chatter about the company.
InterMune shares, which had tanked 80 percent after the drug was denied U.S. regulatory approval in May, more than doubled to $30.57 Friday morning on Nasdaq. About 12 million shares had traded hands, 21 times the stock's average volume.
Analysts said the European panel's decision on the drug Esbriet came much earlier than expected and removed a long-pending overhang on the stock.
"This is a huge positive for the stock because expectations were fairly low and there is minimal visibility into regulatory review in Europe," Robert Baird & Co analyst Thomas Russo said.
Esbriet is being developed for the treatment of mild to moderate idiopathic pulmonary fibrosis (IPF) -- a rare, fatal condition where lungs suffer scarring due to unknown causes.
Esbriet, which is already marketed in Japan under the brand name Pirespa by Shionogi & Co Ltd (4507.T), has orphan drug designation in Europe, giving it 10 years of marketing exclusivity in all 27 member countries of the European Union.
Most analysts expect the drug to be worth $30,000-$50,000 per patient per year and hit peak sales of $1 billion in Europe by 2016-17.
InterMune expects to get European approval for Esbriet by February or March and said it would first launch the drug in Germany in the third quarter of 2011, and follow with launches in France, Spain, Italy and the UK by the middle of 2012.
Canaccord Genuity analyst Adam Cutler expects the company, which has been viewed as an attractive takeover target, to be profitable as soon as the end of 2011.
Think Equity LLC analyst Brian Skorney said, "A number of big pharmas like Bristol-Myers Squibb (BMY.N), Novartis AG NOVN.VX, Pfizer Inc (PFE.N), which are in look out for orphan designated drugs in inflammatory and pulmonary indications, will find InterMune attractive."
Skorney said today's announcement was unlikely to effect the U.S. Food and Drug Administration's decision regarding the drug, but said the agency was likely to come under political pressure given the larger need and the EU recommendation.
In May, the FDA had asked InterMune to conduct a new clinical trial to prove the drug's efficacy. [ID:nSGE6440KB]
"The FDA will ultimately require another clinical trial, but the company won't probably start another trial before the end of 2011," Skorney said. (Reporting by Krishnakali Sengupta in Bangalore; Editing by S. John Tilak, Anne Pallivathuckal)
