CTL Sends FDA’s Sharfstein Letter Requesting Promised but Undelivered Expedited Review
March 18th, 2010 | Posted by Rory Kearney
Dr. Sharfstein,
Can you please check with CBER and see why it is taking them so long to make a final decision on Dendreon’s Provenge.
The pending BLA is an amended BLA that was first submitted to the FDA in 2006. Following a March 2007 AC, in which the FDA hand picked experts overwhelmingly voted for approval, CBER decided to require additional proof of efficacy. That additional proof, as set forth in the SPA, was in fact obtained by Dendreon with results being announced in April 2009 (interim data was also positive and the IDMC also recommended approval in October 2008).
Now CBER has had all the new clinical data from the IMPACT trial as of July 2009 and all the CMC data since October 2009. Despite promises from CBER to the advocacy group CareToLive and others that they would review this treatment, intended for late stage prostate cancer, expeditiously, the treatment inexplicably remains unavailable.
This review is hardly being done expeditiously. FDA has now delayed this treatment from reaching patients for 3 years.
Please inquire/help.

Why would it take so long for FDA to approve since the data is not new, they looked at it once before. I’m afraid the FDA will reject Dendreon’s Provenge for late stage prostate cancer or there would have been approval by now what are they waiting for?
