NEW YORK -- Shares of NPS Pharmaceuticals Inc. surged to their highest price in more than six years Friday as investors hope that a Food and Drug Administration advisory panel will recommend that the FDA approve NPS' bowel drug Gattex.

THE SPARK: The FDA's Gastrointestinal Drugs Advisory Committee will discuss Gattex at a meeting on Tuesday, and the panel's questions were posted to the FDA website on Friday. The committee will make a recommendation on whether to approve the drug to the FDA, which is scheduled to issue a decision by Dec. 30. The FDA is not required to follow the advice of its panels, but if often does so. A positive recommendation makes it more likely that a drug will be sold to consumers.
