BOSTON, Mass. (


) -- I've updated the calendar (

last posted in June

) of expected U.S.

Food and Drug Administration

approval decisions.

These can be make-or-break events for drug and biotech companies, so naturally, FDA decisions often move stocks significantly.

The following calendar covers most of the expected drug approval decisions by the FDA through the end of the year. To be included in this FDA calendar, a drug must already be submitted and under review by the agency.

I put the calendar together using company reports and the


service from Sagient Research -- a handy, subscription-based tool for keeping track of biotech and drug catalysts.

Let's start with updates on upcoming FDA approval decisions:

Hemispherx Biopharma


Drug/indication: Ampligen for chronic fatigue syndrome

FDA decision date: May 25

Hemispherx announced May 26 that the FDA requested a "brief delay" of one to two weeks to take action on the Ampligen application. But on a July 22 conference call, the company said it may get a response from the FDA in the fall.

Spectrum has a new FDA approval decision date following a July 5 request from the agency for additional clinical data. Spectrum submitted that data on July 9. Spectrum is seeking an expansion to the label for Zevalin to include consolidation therapy for patients with NHL. Zevalin is an effective drug that has been a commercial disappointment, so the company hopes the expanded FDA label will boost sales.

Drug/indication: Xiaflex for Dupuytren's contracture

FDA decision date: Aug. 28

FDA advisory panel date: Sept. 16

Xiaflex is designed to dissolve collagen deposits that form cords around joints in the hands and cause the fingers to contract and become inflexible. Notice that the advisory panel's review of Xiaflex is scheduled for after the FDA approval decision date, which likely means a delay.

FDA decision date: Sept. 16
