May 26 (Reuters) - InterMune Inc ITMN.O said it will cut about 40 percent of its workforce and expects to save nearly $12 million annually.
The company, struggling with the recent regulatory rejection of its experimental lung drug, said it expects to take related charges of about $2.4 million in the second quarter.
In a regulatory filing, InterMune said the job cut of 60 employees in the commercial and discovery research area is expected to be completed by the end of June.
Earlier this month, the U.S. Food and Drug Administration refused to approve InterMune's pirfenidone to treat idiopathic pulmonary fibrosis -- a condition in which the lungs suffer scarring due to unknown causes -- and asked for a new clinical trial to prove it works. [ID:nSGE6440KB]
