BioSpecifics Technologies Corporation (BSTC) Announces 30 Month Safety Update for XIAFLEX® in Dupuytren's Contracture



9/6/2012 11:06:23 AM

LYNBROOK, N.Y., Sept. 5, 2012 /PRNewswire/ -- BioSpecifics Technologies Corp. (NASDAQ: BSTC), a biopharmaceutical company developing first in class collagenase-based products marketed as XIAFLEX in the U.S. and XIAPEX® in Europe and Eurasia, today announced a safety update following 30 months of post-approval use in the U.S. of XIAFLEX for the treatment of adult Dupuytren's contracture patients with a palpable cord. As reported by BioSpecifics' strategic partner Auxilium Pharmaceuticals, Inc. (Auxilium), after approximately 27,000 injections were administered to approximately 21,000 patients in the U.S., there was no clinically meaningful change in the nature of events expected relative to the clinical trial safety profile.

"We are very encouraged by the continued low number of adverse events reported since the U.S. launch of XIAFLEX for Dupuytren's contracture patients, which we believe reaffirms the excellent safety profile of XIAFLEX," said Thomas L. Wegman, President of BioSpecifics. "These data also demonstrate the success of Auxilium's physician and sales force training programs and we look forward to the launch of its pilot program for select rheumatology clinics later this year."

From February 2, 2010 through July 31, 2012, approximately 1,454 adverse events have been reported to Auxilium. Of those reported events, the most commonly reported events were laceration, peripheral edema (swelling) and contusion (bruising). Adverse event reporting requirements post-approval are different from requirements for reporting such events during a clinical trial. See "About Voluntary Safety Reporting to Auxilium" below for more information.

In Auxilium's Phase III clinical trials for registration, three (0.3%) subjects experienced a tendon rupture and one (0.1%) subject experienced ligament damage (pulley rupture) following XIAFLEX treatment of 1,082 subjects in the safety database. In the U.S. post-marketing period, 19 tendon ruptures (0.09%) and 3 ligament injuries (0.01%) from approximately 21,000 patients treated with commercial drug were reported. Additionally, there has been a single report of complex regional pain syndrome (0.005%), that resolved within approximately 3 months, and a single case of residual stretch neuropraxia (numbness without pain) (0.005%) with full finger extension and remote from the injection site. Since the U.S. launch by Auxilium, nearly 2,000 U.S. physicians have injected palpable cords in Dupuytren's contracture patients with XIAFLEX.

About Voluntary Safety Reporting to Auxilium

According to Auxilium, with any voluntary safety reporting system, such as that in the U.S., there are limitations regarding interpretation of the data. The system relies on reporting of events from physicians, patients, and other healthcare providers. Auxilium employees also are trained to report events of which they are made aware. The above estimates are based upon voluntary reporting and reflect all information available to Auxilium from February 2, 2010 thru July 31, 2012 for the use of XIAFLEX in adult patients with Dupuytren's contracture with a palpable cord in the U.S.
