Drug developer Facet Biotech Corp. (FACT) told its shareholders Thursday not to tender their holdings to Biogen Idec Inc.'s (BIIB) $356 million takeover offer, a bid the company had already called "inadequate" and "not in the best interest" of shareholders.

Biogen launched the tender offer last week, taking the bid directly to shareholders. Facet at the time recommended shareholders take no action.

The bid of $14.50 a share is below where the stock has been trading since it was made last month. The stock closed Wednesday at $17.29, illustrating investors' belief that a deal between the two companies would need to be done at a higher price.

Biogen made its latest bid public after Facet rejected earlier takeover approaches.

Facet President and Chief Executive Faheem Hasnain had said "it does not appear to be a coincidence" that Biogen made its offer within weeks of the companies' decision to start a phase 3 trial for multiple-sclerosis treatment daclizumab.

On Thursday, Hasnain said the company "remains open to appropriate opportunities" to create shareholder value.

The companies have worked together since 2005 on treatments for multiple sclerosis and solid tumors. A deal would come as larger drug makers have been looking at smaller drug developers as ways to replenish their pipelines.
