LYNBROOK, N.Y., May 19, 2014 /PRNewswire/ -- BioSpecifics Technologies Corp. (NASDAQ: BSTC), a biopharmaceutical company developing first in class collagenase-based products marketed as XIAFLEX® (collagenase clostridium histolyticum or CCH) in the U.S. and XIAPEX® in the EU, today announced that new analyses of data evaluating the use of XIAFLEX in adult men with Peyronie's disease were presented by BioSpecifics' partner, Auxilium Pharmaceuticals, Inc. (Auxilium) at the 2014 Annual Meeting of the American Urological Association (AUA) being held in Orlando, Florida on May 16-21, 2014.

"The new data presented at AUA highlight the benefit, safety and ease of use of XIAFLEX in this patient population as well as elaborate on physician training that may increase urologists' familiarity with XIAFLEX and the injection technique. We feel these analyses further support the commercial potential of this product," said Thomas L. Wegman, President of BioSpecifics. "We are very optimistic about the market potential of XIAFLEX for Peyronie's disease, particularly based on numbers we reported from the first quarter of 2014 of vials shipped and the impressive growth seen in the month of April. We hope this momentum continues as physicians and patients become more comfortable with the procedure and product profile."

XIAFLEX was approved by the U.S. Food & Drug Administration (FDA) in December 2013 for the treatment of Peyronie's disease in men with a palpable plaque and a curvature of 30 degrees or greater at the start of therapy. The product became commercially available in January 2014. XIAFLEX was already approved in the U.S., EU, Canada and Australia for the treatment of adult Dupuytren's contracture patients with a palpable cord in the palm.

The presentations from the AUA meeting included new analyses from the pivotal IMPRESS (The Investigation for Maximal Peyronie's Reduction Efficacy and Safety Studies) trials, the Phase 3 studies that evaluated XIAFLEX for the treatment of Peyronie's disease. Highlights include:

  • 75 percent of men with Peyronie's disease treated with XIAFLEX in the IMPRESS pivotal studies had a clinically meaningful improvement in their penile curvature deformity by the end of the trials. These subjects reported an improvement of 25 percent or greater in penile curvature deformity.
  • An injection simulator using a "smart syringe" was developed to provide clinicians an opportunity to practice the XIAFLEX injection technique. Use of such a model in physician training may increase urologists' familiarity with the injection technique for XIAFLEX treatment of Peyronie's disease by providing both visual and tactile feedback during simulated injection.
  • The administration of a second XIAFLEX injection 1, 2 or 3 days after the first injection during Treatment Cycle 1 did not impact the safety or effectiveness of XIAFLEX in the treatment of Peyronie's curvature deformity evaluated at Week 6. The improvement in curvature deformity and safety measurements were comparable regardless of when the second injection was administered during the first treatment cycle. These data support flexibility in planning XIAFLEX treatment cycles.
