BioSpecifics Announces Positive Results From
Clinical Trial in
Canine Lipomas
- Announces Initiation of Larger Clinical Trial -
LYNBROOK, NY - January 6, 2011 BioSpecifics Technologies Corp. (NASDAQ: BSTC; the Company or BioSpecifics), a biopharmaceutical company developing first in class collagenase-based products, today announced promising results from its study Chien-802 showing dramatic reductions in canine lipoma following injections with purified injectable collagenase. These results build upon an earlier dose escalation study from which the Company selected the dose for Chien-802. The Company also announced today the initiation of a larger clinical trial, Chien-803, for the same indication.
Canine lipomas represent a potentially large market with the
current cost of treating canine lipomas on an annual basis of approximately $635
million in the United States. BioSpecifics previously announced results from a
human clinical trial that demonstrated an average of 93% post treatment decrease
in the size of a lipoma with a single collagenase injection in human lipoma.
We are excited about the promising study results in lipoma and are enthusiastic
about the use of injectable collagenase both in humans and in canines,
commented Thomas L. Wegman, President of BioSpecifics. BioSpecifics is deeply
committed to conducting additional clinical trials that demonstrate the
potential of injectable collagenase in a range of indications. We believe that
new indications have the potential to have a major impact on the market for
injectable collagenase.
About Chien-801 and Chien-802 Clinical Trials
Chien-801 was a pilot study conducted for the purpose of evaluating the use of
purified collagenase for the non-surgical treatment of lipoma in six dogs. The
study evaluated the appropriate dosage and frequency of injections necessary to
significantly reduce the size of the lipoma. The dose administered ranged from
0.012 to 0.021 mg/cm2 which was approximately ½ to ¾ of the dose used in
previous human clinical trials. Based on this dose escalation study the Company
selected the dose for Chien-802.
Chien-802 was designed to evaluate the efficacy of injectable
collagenase in canine lipoma in four healthy dogs with subcutaneous lipomas.
Inclusion criteria required the lipoma to be benign, superficial and easily
measureable. All dogs had a second lipoma that was untreated and used as a
control. At 90 days post injection, in the three evaluable dogs, the lipoma size
was 0%, 0% or 7% of the original size as measured by a CT scan. By contrast, the
untreated lipomas were 129%, 113% and 128% of the original size at day 90. Thus,
the treated lipomas showed a 97% reduction in the size of the lipoma and an
increase in the size of the untreated controls of 23%. Based on the positive
results from Chien-802, BioSpecifics has begun enrollment in a randomized,
double-blind, placebo-controlled study designed to evaluate the efficacy of
purified collagenase for injection for the treatment of canine lipomas.
The Companys preliminary results from an ongoing marketing
survey indicate that veterinarians perform lipoma excision surgery on an average
of 25 dogs per year, costing approximately $635 million annually.
The American Veterinary Medical Association estimates that 47,000 veterinarians
practice on small animals. Based on the data from BioSpecifics survey of
veterinarians, the veterinarians estimate that they would use injectable
collagenase on an average of 22 dogs per year. BioSpecifics believes that the
total potential market for purified collagenase for the treatment of canine
lipomas could be 1 million injections in the Unites States annually.
BioSpecifics strategic partner, Auxilium Pharmaceuticals, Inc. (Auxilium), has
the option to license development and marketing rights to this indication, which
would trigger an opt-in payment and potential future milestone payments from
Auxilium to BioSpecifics. If Auxilium chooses not to exercise this option,
BioSpecifics plans to proceed with the development of its injectable collagenase
for veterinary indications on its own.
About Chien-803 Clinical Trial
The trial will enroll 25 canines, each having two or more lipomas. To meet the
primary endpoint an animal must achieve at least a 50% decrease in the
drug-treated lipoma volume relative to baseline as measured by CT scan at 3
months post injection. The Company expects to announce top-line results from
this trial in the second half of 2011.
Human Lipoma Study Results
BioSpecifics previously conducted an open label study evaluating the safety and
efficacy of injectable collagenase in the treatment of human lipoma. Eleven of
the twelve subjects completed the follow up scheduled for the trial. Patients in
the study received a single injection of collagenase consisting of 1,000 units
(0.058 mg) per centimeter diameter of the lipoma. Subjects were evaluated at
baseline prior to the administration of study treatment and at one, three, seven
and fourteen days, and one, three and six months post treatment to evaluate the
overlying skin as well as the general area for untoward effects. Results showed
that there was an average reduction of lipoma size of 93% post treatment at six
months.
About Canine Lipomas
Lipomas are encapsulated fat deposits that occur under the skin. Lipomas that
restrict motion in older dogs are a serious problem; the only proven therapy for
this condition is surgical excision of the lipoma, which necessarily involves
the use of general anesthesia; it has been estimated that up to 2% of sick dogs
die as a complication of general anesthesia.1 Lipomas occur in
2.3% of the dog population, 2 or in approximately 1.7 million dogs in
the U.S.3
