Biotech and Pharma stocks News; BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX) Completes Both Pivotal LibiGel® Efficacy Trials

LINCOLNSHIRE, Ill. - October 4, 2011 (Investorideas.com newswire) - BioSante Pharmaceuticals, Inc. (NASDAQ:BPAX) today announced completion of its two pivotal LibiGel (testosterone gel) efficacy trials, required for the company's anticipated LibiGel new drug application (NDA). The final visit of the last subject enrolled in the second of the two pivotal LibiGel Phase III efficacy trials occurred at the end of September. LibiGel is in development for the treatment of female sexual dysfunction (FSD), specifically, hypoactive sexual desire disorder (HSDD) in menopausal women, for which there is no FDA-approved product.
Data are being collected from the 141 investigative sites in the U.S. and Canada that participated in the two trials, and BioSante expects to announce top-line LibiGel efficacy results during this quarter. Both efficacy trials were conducted according to an FDA-agreed special protocol assessment (SPA). The third and last pivotal study for the LibiGel clinical development program is the ongoing LibiGel Phase III cardiovascular and breast cancer safety study, which has completed enrollment of 3,656 subjects. The primary analysis of safety data is targeted for third quarter of 2012. The LibiGel NDA submission will include data from the two efficacy trials as well as the safety study and is targeted for the fourth quarter of 2012.
"We are delighted to have completed both LibiGel Phase III efficacy trials. We appreciate the diligence of the investigative sites and their care of the subjects in the trials, and we also thank the participating subjects," noted Joanne Zborowski, BioSante's vice president of clinical development. "There were over 1,100 subjects enrolled in the two efficacy trials, and we look forward to analyzing the data and announcing the results later this year."
About LibiGel®
LibiGel is a testosterone gel in Phase III clinical development for the treatment of women who suffer from female sexual dysfunction (FSD), specifically hypoactive sexual desire disorder (HSDD). The completed Phase III efficacy trials are double-blind, placebo-controlled trials that enrolled over 500 surgically menopausal women each for six-months of therapy. The completed efficacy trials were conducted according to an FDA-agreed special protocol assessment (SPA) agreement. LibiGel is absorbed quickly through the skin after applying a once-daily pea-sized topical application on the upper arm that delivers testosterone to the bloodstream evenly over time.
In a Phase II trial, LibiGel significantly increased the number of satisfying sexual events in surgically menopausal women suffering from HSDD 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.
In addition, BioSante is conducting the Phase III LibiGel safety study, a randomized, double-blind, placebo-controlled, multi-center, cardiovascular (CV) events and breast cancer study that has completed enrollment of 3,656 women and has accrued over 4,800 women-years of exposure, to date. The study will continue for a total of five years; however, BioSante will use the safety study data as part of an NDA submission after the last subject enrolled has completed 12 months of exposure to LibiGel or placebo.
The LibiGel safety study is tracking a predefined list of CV events, in agreement with the FDA, including CV death, myocardial infarction and stroke in women 50 years of age or older and suffering from at least two CV risk factors including hypertension and diabetes. The objective of the safety study is to demonstrate the relative safety of testosterone compared to placebo in the number of CV events. The incidence of breast cancer also is being tracked over the course of the study. The study represents the largest data base of the safety of testosterone in women.
Upon completion of the statistical analyses of the safety study and efficacy trials, BioSante intends to submit an NDA to the FDA, requesting approval of LibiGel for the treatment of HSDD in menopausal women. The NDA submission is targeted for the fourth quarter of 2012.
