BioSpecifics Technologies Corp. Announces Presentation of Encouraging Preclinical Data for CCH from Collaborative Uterine Fibroid Study with Duke Medicine

Oct 16, 2014

LYNBROOK, N.Y., Oct. 16, 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, announces that a paper titled, "Stiffness of Human Uterine Fibroids is Reduced After Treatment with Purified Clostridial Collagenase due to Collagen Degradation" was presented at the Mechanotransduction in the Reproductive Tract conference hosted by the Campion Fund of the Phyllis and Mark Leppert Foundation for Fertility Research in Durham, North Carolina. The data being presented show that highly purified collagenase can reduce the rigidity of human uterine fibroid tissue and potentially shrink uterine fibroid tumors by interrupting the accumulation of poorly aligned and altered collagen.

"The preclinical data presented today are very promising and contribute to the much needed development of a non-surgical treatment option for uterine fibroids," commented Thomas L. Wegman, President of BioSpecifics. "Accumulation of collagen in uterine fibroid tumors is thought to contribute to the many morbidities associated with the condition and we aim to further show how CCH can lead to improved patient outcomes. We are working on our development plans for this indication and will update you once we have those finalized."

The preclinical results were presented by Dr. Friederike Jayes, D.V.M., Ph.D. of Duke Medicine, at a session focused on mechanical signaling and its relationship to uterine fibroid formation. In the ex vivo study, uterine fibroid tissues from eight patients were injected with 50 microliters of highly purified CCH at four different dose levels (0-1-2-4 mg/ml), and compared to uninjected tissue as a control. Following incubation (37 degrees C for 0-24-48-72-96h), tissue samples were confirmed for high collagen content through Masson-Trichrome staining and tested by rheometry to measure stiffness. Collagen content degradation was evident at all dose levels after 96 hours and collagen fibrils were undetectable under electron microscopy in tissue treated with the highest dose. Treatment with 1 mg/ml caused significant softening after 24 hours to 4005+/-608 Pa compared to vehicle-injected controls (7416+/-801 Pa; p<0.007). The 2 and 4 mg/ml treatments resulted in significantly decreased stiffness after 24 hours (3145+/-689 Pa; p<0.0005) and 96 hours (1440+/-115 Pa; p<0.0005). A significant decrease in stiffness was achieved with all doses and at all time points.

This collaborative study is being conducted with support from BioSpecifics by researchers at Duke Medicine including Dr. Jayes and Dr. Phyllis Leppert, a Professor of Obstetrics and Gynecology and Professor of Pathology at Duke Medicine. 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 the National Institutes of Health which demonstrated that disorganized interstitial collagens are a major component of uterine fibroids.

About Uterine Fibroids

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. Uterine fibroids have been estimated to cost up to $34 billion annually in the U.S.
