BOSTON (TheStreet) -- News of a drug's approval or rejection from the U.S. Food and Drug Administration can rock or kill a biotech stock's price. Here is an updated FDA calendar that shows 14 companies -- in chronological order -- with drugs facing FDA approval decisions through October 2010.

Cell Therapeutics ( CTIC)

Drug/indication: Pixantrone for non-Hodgkin's lymphoma

Pozen ( POZN)

Drug/indication: Vimovo for pain relief

Dendreon ( DNDN)

Drug/indication: Provenge for prostate cancer

Approval decision date: May 1

The FDA has given no indication that it plans to hold an advisory panel meeting to review the Provenge application. A similar panel meeting was held in 2007, which voted to recommend the drug's approval.

InterMune ( ITMN)

Drug/indication: Pirfenidone for idiopathic pulmonary fibrosis

Approval decision date: May 4

An FDA advisory panel held March 9 voted to recommend the approval of pirfenidone for the treatment of idiopathic pulmonary fibrosis. The positive vote sent InterMune shares higher.

Prior to the FDA's approval decision date, an FDA advisory panel will review the safety and efficacy of Acthar on May 6. The FDA's review of Acthar is expected to post to the agency's web site on May 4 or May 5.

Drug/indication: Gilenia for multiple sclerosis

Approval decision date: June 2010 (Novartis has not disclosed the exact date.)

The FDA is holding an advisory committee meeting on June 10 to review Gilenia. If approved, Gilenia would be the first multiple sclerosis drug administered as a pill, and as such, the drug could have an impact on already approved, injectable MS drugs from Biogen Idec ( BIIB), Teva ( TEVA) and Merck-Serono.

Savient Pharmaceuticals ( SVNT)

Drug/indication: Krystexxa for gout

Approval decision date: Sept. 14

The FDA refused to approve Krystexxa last August, citing problems with the way the drug is manufactured. Savient revised the Krystexxa manufacturing process and submitted a response in March to the FDA's complete response letter.

Javelin Pharmaceuticals ( JAV)

Drug/indication: Dyloject for acute moderate-to-severe pain in adults

Approval decision date: Oct. 3

If approved, Dyloject will be the first IV non-steroidal anti-inflammatory drug (NSAID) marketed in the U.S. as a single agent for the management of acute moderate-to-severe pain in adults since ketorolac in 1990. The active ingredient in Dyloject is diclofenac sodium, a widely prescribed oral NSAID.
