[April 02, 2014]  (Reuters)   MannKind Corp's shares nearly doubled before the bell on Wednesday, after an advisory committee to the U.S. health regulator recommended approval for the drug developer's inhaled insulin treatment.

The panel on Tuesday voted 13-1 to recommend approval for patients with type 1 diabetes and unanimously backed it for those with type 2, adding that longer-term studies would still be required to gauge the risk of lung cancer.

Analysts said that while the drug was likely to receive approval, efficacy and safety concerns raised by the panel and the agency could delay the decision, which is due on April 15.

"Given the number of issues flagged by FDA during the review especially for the type 1 diabetes indication there is still a possibility that MannKind may be asked to conduct yet more studies prior to approval to provide better evidence to support the targeted patient population," Guggenheim analysts said in a note.

The FDA staff raised questions about dosing, missing data, bronchospasms, or constriction of the air passages of the lung, and Afrezza's effect on lung function, but raised no major new safety concern in their review of Afrezza on Friday.
