BioSpecifics Technologies Corp. Announces Positive Data from Phase 2a Study of CCH for Treatment of Cellulite
LYNBROOK, N.Y., Aug. 21, 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 positive, statistically significant results from a randomized, double-blind Phase 2a study of CCH for the potential treatment of cellulite, or edematous fibrosclerotic panniculopathy. The results showed that all three doses of CCH used in the study, including a low, medium and high dose, demonstrated an improvement in the appearance of cellulite as measured by the trial endpoints of physician and patient-assessed improvements. CCH was well-tolerated by all dose groups with most adverse events being mild to moderate and primarily limited to the local injection area.
"These positive results are very encouraging, particularly because both patients and physicians saw a statistically significant improvement in the appearance of cellulite after CCH treatment," commented Thomas L. Wegman, President of BioSpecifics. "The market for cellulite treatment is large, which makes these data very exciting for the prospective commercial success of CCH in this indication. The results also position CCH as a potential treatment for other aesthetic needs, so we are eager to see continued progress by Auxilium in initiating a subsequent Phase 2b trial of CCH in cellulite in the second quarter of 2015."
The Phase 2a study was conducted by BioSpecifics' strategic partner Auxilium Pharmaceuticals, Inc. (Auxilium) and enrolled 150 women between the ages of 18 and 45 in the U.S. Each subject received up to three treatment sessions of drug or placebo according to randomization (5 high-dose (0.84mg): 5 mid (0.48mg): 5 low (0.06mg): 3 placebo) and each treatment session was approximately 21 days apart. Up to 12 injections were administered into cellulite dimples during each session across an entire treatment quadrant – left or right buttock or left or right posterior thigh. Only the dimples treated on Day 1 were able to be retreated on Day 22 (Treatment Session 2) and Day 43 (Treatment Session 3) if, in the opinion of the investigator, the dimple continued to be evident. A variable number of dimples were able to be treated within one treatment quadrant.
The primary trial endpoint was an investigator and a patient score on the Global Aesthetic Improvement Scale (GAIS), which is an FDA-recognized scale developed as an assessment of degree of improvement, and adapted by Auxilium for use in the cellulite study. Investigators and patients used the respective GAIS to compare a Day 1 pretreatment digital image of their cellulite to their treatment results. A score of -1 indicated that the results were "Worse." A score of 0 indicated "No Change." A score of +1 indicated "Improved." A score of +2 indicated "Much Improved" and a score of +3 indicated "Very Much Improved." Additional study endpoints included Physician and Patient-assessed Composite Responder Analyses.
Key Results from this Study Include:
- Both the mid and high dose groups of CCH demonstrated a statistically significant improvement in investigators' assessments of the appearance of cellulite, as measured by GAIS scores, with a p-value of <0.05 versus placebo, as well as in patients' assessments of the appearance of cellulite, as measured by GAIS scores, with a p-value of <0.02 versus placebo.
- 68 percent of both the mid and high dose groups reported being "Satisfied" or "Very Satisfied" with their cellulite treatment, compared to only 34 percent of placebo patients.
- Both the mid and high dose groups of CCH demonstrated a statistically significant improvement in the post-hoc composite responder analysis, as measured by combined investigator and patient GAIS scores, with p-values of 0.021 and 0.004, respectively, versus placebo.
- While the trial was not designed to quantify changes in cellulite dimple measurements, 3-D photography was utilized to enable visualization of treatment effects. View photos here.
- CCH was well-tolerated by all dose groups with most adverse events being mild-to-moderate and primarily limited to the local injection area; 86 percent of all related adverse events resolved within 21 days and there was only one serious adverse event in the trial, determined to be unrelated to the treatment drug.
Edematous fibrosclerotic panniculopathy, commonly known as cellulite, describes a condition in which lobules of subcutaneous adipose tissue extend into the dermal layer. Cellulite can involve the loss of elasticity or shrinking of collagen cords, called septae, that attach the skin to lower layers of muscle. When fat in cellulite prone areas swells and expands, the septae tether the skin, which causes surface dimpling characteristic of cellulite. These changes can visibly affect the shape of the epidermis and resemble an orange peel-like dimpling of the skin.
