Auxilium Pharmaceuticals, Inc. To Present CCH Data For Concurrent Treatment Of Multiple Dupuytren's Cords At ASSH Annual Meeting

CHESTERBROOK, Pa., Aug. 28, 2014 /PRNewswire/ -- Auxilium Pharmaceuticals, Inc. (NASDAQ: AUXL), a specialty biopharmaceutical company, today announced that data from trials evaluating the use of collagenase clostridium histolyticum (CCH) for treating two Dupuytren's contracture (DC) cords concurrently in adult patients with a palpable cord will be presented at the upcoming 69^th Annual Meeting of the American Society for Surgery of the Hand (ASSH) being held in Boston on September 18-20, 2014. XIAFLEX^® (CCH) is a biologic approved in the U.S., EU, Canada and Australia for the treatment of adult DC patients with a palpable cord.

DC is a progressive hand disease that can present with multiple collagen "cords" that limit finger movement and hand function. It is estimated that 35 to 40 percent of annual surgical procedures in the U.S. are performed to treat more than one DC cord at a time¹.

The AUX-CC-867 MULTICORD (MULtiple Treatment Investigation of Collagenase Optimizing the Resolution of Dupuytrens) study data examining the effect of delayed finger extension on patients who received two concurrent injections of CCH to treat two affected joints in the same hand were selected for the meeting's Best Paper Session. Additional findings from the MULTICORD study featured in meeting presentations include the safety and efficacy of CCH as a treatment for two affected joints in the same hand concurrently and an analysis of efficacy based upon baseline joint severity. Additionally, a podcast has been selected for presentation that describes an analysis of the MULTICORD study treating two affected joints in the same hand concurrently using local anesthesia prior to finger extension. Finally, data will also be presented from the AUX-CC-862 retreatment study examining the retreatment of recurrent contractures in DC joints that were previously treated with CCH.

"The data presented at this year's Annual ASSH Meeting help support the efficacy and safety profile of CCH as a non-surgical treatment option for treating two cords concurrently during one office procedure, expanded flexibility with timing of the finger extension procedure and the retreatment of recurrent joints in those who were previously treated with CCH," said Adrian Adams, Chief Executive Officer and President of Auxilium Pharmaceuticals.

Data to be presented on CCH include:

The U.S. Food and Drug Administration is reviewing the Company's submission of a supplemental Biologics License Application (sBLA) requesting approval of XIAFLEX for the treatment of two Dupuytren's cords concurrently. The PDUFA date for the sBLA is October 20, 2014.

About Dupuytren's Contracture (DC)
DC is a progressive condition affecting the hand, specifically the layer of tissue just under the skin of the palm and fingers. While this layer of tissue normally contains collagen, in patients with DC there is an increase in the amount of collagen produced. Abnormal collagen build-up results in nodule and cord formation that worsens over time. Eventually, rope-like collagen cords may form, thicken and shorten, causing the fingers to be drawn in toward the palm. This thickening and shortening of the Dupuytren's cord can reduce the finger's range of motion (how much a person can move or straighten them). Once the Dupuytren's collagen cord can be felt, it is referred to as a "palpable cord." ^1,2

About XIAFLEX
XIAFLEX (collagenase clostridium histolyticum, or CCH) is a biologic approved in the U.S., EU, Canada and Australia for the treatment of adult Dupuytren's contracture (DC) patients with a palpable cord and in the U.S. for the treatment of adult men with PD with a palpable plaque and penile curvature deformity of at least 30 degrees at the start of therapy. XIAFLEX consists of a combination of two subtypes of collagenase, derived from Clostridium histolyticum. Together, the collagenase sub-types are thought to work synergistically to break the bonds of the triple helix collagen structure. XIAFLEX has been granted Orphan status in the U.S. by the FDA for DC and PD.
