FDA acknowledges complete response for PCa Rx application
Dendreon Corp. has received written acknowledgement from FDA that its amended biologics license application (BLA) for sipuleucel-T (Provenge) is a complete response. FDA has set May 1, 2010 as the date by which it will respond to the amended BLA.
The BLA includes data from the IMPACT (IMunotherapy for Prostate AdenoCarcinoma Treatment) trial, which was conducted under a Special Protocol Assessment agreement with FDA. Dendreon is seeking licensure for sipuleucel-T, a form of active cellular immunotherapy, for the treatment of men with metastatic castrate-resistant prostate cancer.
The new drug application (NDA) for hexaminolevulinate for detection of noninvasive papillary bladder cancer may be approved by FDA pending premarket approval for the Karl Storz photodynamic diagnosis system and final agreements between manufacturer Photocure and FDA on labeling and post-marketing commitments, Photocure announced.
Photocure submitted the NDA on June 30, 2009 and achieved a priority review in August 2009. The company said it expects the pending issues to be agreed upon with FDA within the first half of 2010.
Included in the NDA are phase III study data that showed a significantly improved detection (p=.001) of noninvasive papillary bladder cancer using hexaminolevulinate compared to standard white light cystoscopy.

Patients who respond to TOK-011 will have the opportunity to continue the treatment in an extension arm of the trial, according to the company.
