Any worries by Promedior Inc. investors after Bristol-Myers Squibb Co. (BMS) backed away last year from its option to acquire the firm were resolved in a big way by last week's news that Roche Holding AG is taking over the company in a transaction valued as high as $1.39 billion. Privately held, Lexington, Mass.-based Promedior's lead asset is PRM-151, a recombinant form of human pentraxin-2 (PTX-2) protein that won breakthrough designation from the FDA earlier this year for idiopathic pulmonary fibrosis (IPF).
