BioSante Pharmaceuticals to Present LibiGel® at International Society for the Study of Women's Sexual Health (ISSWSH) Annual Meeting
LINCOLNSHIRE, Illinois (February 21, 2007) – BioSante Pharmaceuticals, Inc. (Amex: BPA) announced today that it has been granted a presentation at the International Society for the Study of Women’s Sexual Health (ISSWSH) Annual Meeting. The ISSWSH meeting is being held from February 22-25 in Orlando, Florida. BioSante will present information regarding Phase II study results and the initiation of a Phase III safety and efficacy study of LibiGel® (transdermal testosterone gel) in the treatment of female sexual dysfunction (FSD). The six-month, double-blind, placebo-controlled Phase III study is planned to enroll approximately 360 surgically menopausal women and is being conducted under a Phase III protocol and investigational new drug application (IND) reviewed by and on file with the U.S. Food and Drug Administration (FDA).
In the Phase II study, LibiGel® significantly increased satisfying sexual events in surgically menopausal women suffering from FSD. The Phase II study 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 study was a double-blind, placebo-controlled study, conducted in the United States, in surgically menopausal women distressed by their low sexual desire and activity.
“We are pleased to be in a position to present and discuss LibiGel at the ISSWSH meeting. ISSWSH is a key professional organization for women’s sexual health. We have initiated our first Phase III study of LibiGel in the large potential FSD market and look forward to speaking with ISSWSH practitioners about our LibiGel efficacy data and new Phase III study," said Stephen M. Simes, president and chief executive officer of BioSante.
“We have moved our LibiGel into Phase III clinical development and are excited to be developing a treatment for female sexual dysfunction which is underserved by the pharmaceutical industry today. LibiGel may help address this unmet medical need. We believe two Phase III safety and efficacy studies plus one year of safety study data are the essential requirements for submission and approval by the FDA of a new drug application (NDA),” Simes continued. “With the initiation of this Phase III LibiGel study and our recent FDA approval of Elestrin™ (estradiol gel), this is a very exciting time for BioSante,” he added.
LibiGel is a gel formulation of bioidentical testosterone designed to be quickly absorbed through the skin after application on the upper arm, delivering testosterone to the bloodstream evenly over time and in a non-invasive and painless manner. Though generally characterized as a male hormone, testosterone also is present in women and its deficiency has been found to decrease libido or sex drive. In addition, studies have shown that testosterone therapy can increase bone density, raise energy levels and improve mood, in addition to boosting sexual desire and activity.
According to a study published in the Journal of the American Medical Association, 43 percent of American women (about 40 million) experience some degree of impaired sexual function. Among the more than 1,400 women surveyed, 32 percent lacked interest in sex and 26 percent could not experience orgasm.
BioSante's hormone product portfolio
In addition to LibiGel, BioSante recently received FDA approval for Elestrin™ (estradiol gel), a fast-drying gel formulation of bio-identical estradiol, in the treatment of moderate to severe vasomotor symptoms (hot flashes) in menopausal women. Elestrin is absorbed through the skin after topical application on the upper arm, and delivers estradiol to the bloodstream evenly over time in a non-irritating, painless manner. Elestrin is administered using a metered dose applicator that delivers 0.87 g of gel per actuation, thereby allowing for precise titration from dose to dose. The gel dries quickly in one to two minutes. Elestrin will be launched in mid-2007 by Bradley Pharmaceuticals, Inc., under a marketing agreement between BioSante and Bradley.
