BioSpecifics Technologies Corp. Announces Data from Collaborative Uterine Fibroid Study Presented at 2013 Society for the Study of Reproduction Annual Meeting

Jul 23, 2013, 08:30 ET from BioSpecifics Technologies Corp.

LYNBROOK, N.Y., July 23, 2013 /PRNewswire/ -- BioSpecifics Technologies Corp. (NASDAQ: BSTC), a biopharmaceutical company developing first in class collagenase-based products marketed as XIAFLEX® (collagenase clostridium histolyticum; CCH) in the U.S., announces that a poster titled, "Biomechanical Evaluation of Human Uterine Fibroids after Exposure to Purified Clostridial Collagenase" was presented today at the Society for the Study of Reproduction 46th Annual Meeting taking place this week in Montreal, Quebec, Canada.  The poster provided data which show that highly purified collagenase can reduce the stiffness of human uterine fibroid tissue in laboratory experiments. Increased tissue rigidity has been implicated as a cause of the morbidity associated with uterine fibroids.

"We believe these results are an important step forward in the potential development of CCH as a treatment for uterine fibroids and we look forward to seeing data from ongoing preclinical research," commented Thomas L. Wegman, President of BioSpecifics. "We are excited to be supporting this innovative research being conducted by Dr. Leppert and Dr. Jayes at Duke Medicine."

Uterine fibroids are benign tumors with significant co-morbidities, which can include pain, decreased fertility, increased rate of miscarriage, heavy menstrual bleeding and frequent urination, and they contain large amounts of collagen. Uterine fibroids are the primary indication for hysterectomy in this country, accounting for anywhere from 33% to more than 40% of the approximately 600,000 hysterectomies each year.1 Uterine fibroids have been estimated to cost up to $34 billion annually in the U.S.2

The results of this ex vivo study show that treatment of fibroids with determined doses of purified collagenase caused a statistically significant decrease in the stiffness of the tissue. This hypothesis was tested in fibroid tissue obtained after hysterectomy or myomectomy surgery from patients. Tissues were injected with collagenase and compared to control-injected tissue.  The stiffness in the fibroid tissue was reduced in a time and dose dependent manner with a p-value ≤ 0.001. 

The study is being led by Dr. Phyllis Leppert, a Professor of Obstetrics and Gynecology and Professor of Pathology and her colleague, Dr. Friederike Jayes at Duke Medicine with support from BioSpecifics. Dr. Leppert is a leading researcher in the molecular biology and development of medical treatments for uterine fibroids.  This work stems from earlier work of Dr. Leppert conducted at NIH which demonstrated that disorganized interstitial collagens are a major component of uterine fibroids.

"Current treatments for uterine fibroids can be quite invasive, and we believe these are promising data which support further studies with purified collagenase to treat uterine fibroids and help the millions of  women worldwide who are suffering from this condition," commented Dr. Leppert.

About BioSpecifics Technologies Corp.

BioSpecifics Technologies Corp. is a biopharmaceutical company that has developed injectable collagenase for twelve clinical indications to date. Injectable collagenase is marketed as XIAFLEX® in the U.S. for the treatment of adult Dupuytren's contracture patients with a palpable cord in the palm by BioSpecifics' partner, Auxilium Pharmaceuticals, Inc., and is approved for Dupuytren's contracture in the EU and Canada. CCH is also in clinical development for the treatment of several additional promising indications. The U.S. Food & Drug Administration has accepted for filing Auxilium's supplemental Biologics License Application for XIAFLEX for the potential treatment of Peyronie's disease. The FDA is expected to take action on the application by September 6, 2013, and, if approved, XIAFLEX will be the first and only biologic treatment indicated for Peyronie's disease. Auxilium is also testing CCH for frozen shoulder syndrome (adhesive capsulitis) and cellulite. Auxilium has reported positive top-line data from a Phase IIa frozen shoulder study and expects to initiate a new clinical trial in the second half of 2013. BioSpecifics is currently managing the clinical development of CCH for the treatment of human and canine lipomas, which are both in Phase II clinical trials, with top-line data from both trials expected in the second half of 2013.
