LYNBROOK, N.Y., Oct. 23, 2013 /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
the EU, today announced that its partner Auxilium Pharmaceuticals, Inc.
(Auxilium) has dosed the first patient in its Phase 2a study of XIAFLEX
("collagenase clostridium histolyticum" or "CCH") for the treatment of
cellulite (edematous fibrosclerotic panniculopathy). Topline results from the
study are expected in the first quarter of 2015.

"We are pleased to report the clinical progress being made for this condition
which affects 85-98% of post-pubertal females and with no FDA approved
treatment options," commented Thomas L. Wegman, President of BioSpecifics. "We
have long believed in the vast potential of XIAFLEX as a treatment for many
indications caused by collagen accumulation and look forward to reporting
top-line data from this trial in the first quarter of 2015 as well as
reporting more near-term milestones including the upcoming PDUFA date for
XIAFLEX in Peyronie's disease which is December 6, 2013."

As reported by Auxilium this morning, the Phase 2a study is a randomized,
double-blind multiple-dose study expected to enroll approximately 144 women
between the ages of 18 and 45 in the U.S. Patients will be evaluated for
treatment efficacy by investigator and patient assessments, as well as 3-D
photographic imaging techniques. The study will be conducted in two stages and
safety will be evaluated through the collection of adverse events. If the
safety and local tolerability profile from the first stage has been found to
be acceptable, subjects will be enrolled in stage 2.

To qualify for the study, participants must have cellulite in the
posterolateral thighs and/or buttocks for at least 12 months prior to a
screening visit. Eligible study participants will be assigned to one of four
groups that vary in treatment dose (low, medium, high, and placebo and will be
randomized to low-dose XIAFLEX, mid-dose XIAFLEX, high-dose XIAFLEX, or
placebo in a 5:5:5:3 ratio. Total treatment doses per treatment session
include doses both lower and higher than the dose used in Dupuytren's
contracture with a palpable cord. Each subject may receive up to three
treatment sessions of study drug according to randomization and each treatment
session will be approximately 21 days apart. In this study, only the dimples
treated on Day 1 may be retreated on Day 22 (Treatment Session 2) and Day 43
(Treatment Session 3) if, in the opinion of the investigator, the dimple
continues to be evident. A variable number of dimples may be treated within
one treatment quadrant.

There are currently no FDA approved pharmaceutical therapies indicated for
cellulite. XIAFLEX treatment is intended to target and lyse, or break, those
collagen tethers that cause the skin dimpling associated with cellulite with
the goal of releasing the dimpling and potentially resulting in smoothing of
the skin.

About Cellulite

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.

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 currently marketed as XIAFLEX^® (collagenase
clostridium histolyticum (CCH)) 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. (Auxilium) and marketed
in Europe and approved in Canada. Swedish Orphan Biovitrum AB has marketing
rights for XIAPEX^® (the EU tradename for CCH) for the treatment of
Dupuytren's contracture and Peyronie's disease in 71 Eurasian and African
countries. Asahi Kasei Pharma Corporation has development and
commercialization rights for XIAFLEX for the treatment of Dupuytren's
contracture and Peyronie's disease in Japan and Actelion Pharmaceuticals Ltd.
has development and commercialization rights for XIAFLEX for these two
indications in Canada, Mexico, Brazil and Australia. CCH is in clinical
development for the treatment of several additional promising indications.
Under the Prescription Drug User Fee Act (PDUFA), the FDA has set an action
date for XIAFLEX for Peyronie's disease of December 6, 2013.Auxilium is
testing CCH for frozen shoulder syndrome and cellulite. A Phase IIa trial of
CCH for cellulite was initiated in the fourth quarter of 2013 and Auxilium
expects to initiate next stage trials of CCH for frozen shoulder syndrome in
the same period. BioSpecifics is currently managing the development of CCH for
the treatment of human and canine lipomas, both of which are in Phase II
trials, and expects to report top-line data from these trials by the end of
2013. For more information, please visit www.biospecifics.com.
