BioSante Pharmaceuticals, Inc. to Present LibiGel Safety Update at ENDO Annual Meeting

LINCOLNSHIRE, Ill.--(BUSINESS WIRE)--Jun 18, 2010 - BioSante Pharmaceuticals, Inc. (NASDAQ:BPAX), will present a LibiGel safety update at the 2010 Annual Meeting of the Endocrine Society (ENDO), being held from June 19-22, 2010 in San Diego, California.

Michael C. Snabes, MD, PhD, BioSante's vice president of clinical development, will give a presentation entitled, “Low Cardiovascular Event Rate in Post-menopausal Women with Increased Cardiac Risk: Findings from the Ongoing Blinded LibiGel (testosterone gel) Cardiovascular and Breast Cancer Safety Study,” on Sunday June 20, 2010. The update will include the results of the third unblinded review of safety data, which included 1,500 women-years of exposure, by the independent Data Monitoring Committee of the LibiGel Cardiovascular and Breast Cancer Safety Study.

BioSante is in Phase III clinical development of LibiGel for the treatment of hypoactive sexual desire disorder (HSDD) in menopausal women under an FDA-approved SPA (Special Protocol Assessment). BioSante is enrolling women in three Phase III clinical studies with a new drug application (NDA) planned for 2011. “There still is no FDA approved pharmaceutical product for the treatment of HSDD and it is clear from the extensive off-label use of testosterone products for HSDD, that women need an approved therapy. We believe LibiGel can be the first product to market for this unmet medical need,” said Dr. Snabes.

The ENDO Annual Meeting features over 200 scientific sessions covering the full breadth of endocrinology—from basic and translational research to clinical practice. The ENDO 2010 scientific program includes 16 Plenary lectures, 140 Case Management Forum & Meet-the-Professor sessions and 78 Symposia—a total of more than 350 presentations from some of the world's leaders in endocrine research & care. With over 7,500 attendees and 2,500 abstracts presented, ENDO offers an excellent venue for scientific exchange.

About LibiGel

LibiGel® is a testosterone gel in Phase III clinical development for the treatment of women who suffer from female sexual dysfunction (FSD). The on-going Phase III efficacy trials 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 special protocol assessment (SPA) agreement.

LibiGel is absorbed quickly through the skin after a once-daily pea-sized application on the upper arm, delivering testosterone to the bloodstream evenly over time and in a non-invasive and painless manner. In a Phase II trial, LibiGel significantly increased the number of satisfying sexual events in surgically menopausal women suffering from FSD 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.
