BioSante Pharmaceuticals Initiates Phase III Study of LibiGel(R) (transdermal testosterone gel) in the Treatment of Female Sexual DysfunctionLINCOLNSHIRE, Ill.--(HSMN NewsFeed)--BioSante Pharmaceuticals, Inc. (Amex: BPA ) announced today that it has initiated a Phase III safety and efficacy trial of LibiGelŪ (transdermal testosterone gel) in the treatment of female sexual dysfunction (FSD). The double-blind, placebo-controlled Phase III trial will enroll approximately 360 surgically menopausal women for a six-month clinical trial, 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).
"Based on discussions with the FDA and our positive results from the LibiGel Phase II study, we are moving forward into Phase III pivotal studies of women with low sexual desire, the largest component of FSD, also known as Hypoactive Sexual Desire Disorder (HSDD)," said Stephen M. Simes, president and chief executive officer of BioSante.
"We are encouraged by the clinically significant improvement in sexual events with LibiGel treatment in the Phase II study," said Michael C. Snabes, MD, PhD, a reproductive endocrinologist and Fellow of the American College of Obstetrics and Gynecology, the American College of Surgeons and the American College of Endocrinology and BioSante's key clinical development consultant. "Since there are no medications approved by the FDA for the treatment of this common disorder, there is significant demand by patients and their physicians. We are hopeful that if and when LibiGel is approved by the FDA that LibiGel treatment will be able to improve the sex lives of women with low sexual desire and activity."
"We are pleased to be moving into Phase III clinical development of LibiGel. Female sexual dysfunction is underserved by the pharmaceutical industry today. LibiGel may help address this unmet medical need. We believe two Phase III safety and efficacy trials plus one year of safety data are the essential requirements for submission and approval by the FDA of a new drug application (NDA)," said Stephen M. Simes. "With the initiation of this Phase III LibiGel trial and our recent FDA approval of Elestrin(TM) (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. The majority of women with FSD are postmenopausal, experiencing FSD due to hormonal changes following menopause, whether natural or surgical.
BioSante's hormone product portfolio
In addition to LibiGel, BioSante recently received FDA approval for Elestrin(TM), 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.
