Favrille

( FVRL) sank after a study of its Favld treatment for non-Hodgkin's lymphoma didn't demonstrate a statistically significant difference in response improvement.

The San Diego-based biotech said the results came in a planned interim analysis of a secondary endpoint in the first 233 patients enrolled in an ongoing pivotal, placebo-controlled Phase 3 clinical trial of FavId following Rituxan-induction therapy in patients with follicular B-cell non-Hodgkin's lymphoma. Shares of Favrille dropped 22% to $3.87.

Nabi Biopharmaceuticals

The agreement temporarily halts the attempt by hedge fund manager Daniel Loeb to oust top management and several board members, including Thomas McLain, Nabi's chairman and CEO. Loeb, who owns 9.5% of Nabi's stock, has been a frequent critic of the company's strategy and has been a vocal advocate for McLain's removal. Shares of Nabi slipped 1.2% to $6.52.

Medical-device maker

Abiomed

(ABMD) - Get Report

dropped 3.6% to $12.40 even though it signed a five-year agreement in which Medix Japan will distribute the company's AB5000 and Impella products.

Abiomed said the deal will be worth $16 million or more. Medix Japan will purchase $11 million of Impella products in the first 18 months following the product's regulatory approval in Japan. The balance of the purchase commitment is for Abiomed's other products and begins in the company's fiscal 2008 first quarter.

Novartis

fell 1.6% to $58.40 after the company said the Food and Drug Administration's review of a new diabetes drug will take another three months. The delay comes as the company submitted more data.

The agency is now expected to act on the drug Galvus in late February. Regulatory delays are never good news for any drug, but the delay is especially difficult for Novartis because Galvus is competing with

said people with the inflammatory disease ankylosing spondylitis showed a sustained improvement in their symptoms over three years while being treated with Enbrel. Still, shares of Amgen were down 1.1% to $72.62.
