BioSante Pharmaceuticals Reports Positive LibiGel(R) Safety Data in Phase
III ProgramFont size: A | A | A8:00 AM ET 8/13/09 | BusinessWire
BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX), today announced positive
safety data in its ongoing LibiGel Phase III clinical development program.
BioSante reported that with over 1,250 women enrolled and almost 825 women-
years of exposure in its LibiGel Phase III clinical development program,
there have been no deaths and only five cardiovascular events. This analysis
of blinded data indicates a very low cardiovascular event rate has occurred
thus far. Therefore, in view of the excellent LibiGel safety profile,
BioSante's LibiGel Phase III development program will continue as planned.
BioSante targets submission to the FDA of a new drug application (NDA) by
mid-2011.
"The cardiovascular safety data indicate that LibiGel, to date, has been
shown to be safe," said Stephen M. Simes, BioSante's president and CEO. "We
are happy to see that LibiGel continues to show its safety in healthy women,
and also in those women with at least two cardiac risk factors enrolled in
our cardiovascular and breast cancer safety study. We will continue to
analyze blinded cardiac event data on a regular basis. LibiGel remains the
only pharmaceutical product in the U.S. in active development for the
treatment of hypoactive sexual desire disorder (HSDD) in menopausal women.
We continue to believe that LibiGel can be the first product approved by the
FDA for this common and unmet medical need also referred to as female
sexual dysfunction (FSD)."
The Phase III Cardiovascular and Breast Cancer Safety Study is a randomized,
double-blind, placebo-controlled, multi-center, cardiovascular events and
breast cancer study that will enroll between 2,400 and 3,100 women, exposed
to LibiGel or placebo for 12 months. An NDA can be filed and reviewed by FDA
, possibly leading to approval of LibiGel, at that time. After NDA
submission and potential approval of LibiGel, BioSante will continue to
follow the women enrolled in the study for an additional four years.
The LibiGel safety study is tracking a predefined list of cardiovascular
events, in agreement with the FDA, including cardiovascular death,
myocardial infarction and stroke, in women 50 years of age or older and
suffering from at least two cardiovascular risk factors including
hypertension and diabetes. The objective of the safety study is to show the
relative safety of testosterone compared to placebo in the number of
cardiovascular events. The incidence of breast cancer also will be tracked
over the course of the study.
In addition to the Phase III cardiovascular and breast cancer safety study,
BioSante is conducting two LibiGel Phase III efficacy trials. The Phase III
efficacy trials of LibiGel in the treatment of FSD are double-blind, placebo
-controlled trials that will enroll up to approximately 500 surgically
menopausal women each for a six-month clinical trial. The efficacy trials
are being conducted under an FDA approved SPA (special protocol assessment
agreement).
As previously announced by BioSante, treatment with LibiGel in a Phase II
clinical trial significantly increased satisfying sexual events in
surgically menopausal women suffering from FSD. The Phase II trial results
showed LibiGel significantly increased the number of satisfying sexual
events by 238 percent versus baseline (p<0.0001); this increase also was
significant versus placebo (p<0.05). In this study, the effective dose of
LibiGel produced testosterone blood levels within the normal range for pre-
menopausal women and had a safety profile similar to that observed in the
placebo group. In addition, no serious adverse events and no
discontinuations due to adverse events occurred in any subject receiving
LibiGel. The Phase II clinical trial was a double-blind, placebo-controlled
trial, conducted in the United States, in surgically menopausal women
distressed by their low sexual desire and activity.
