BioSante Pharmaceuticals, Inc. Presents LibiGel® Clinical and Market Information at ISSWSH Conference

LINCOLNSHIRE, Illinois (February 17, 2009) – BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX), presented LibiGel clinical and market information at the 2009 Annual Meeting of the International Society for the Study of Women’s Sexual Health (ISSWSH).

Michael C. Snabes, MD, PhD, BioSante’s vice president of clinical development, presented on Friday February 13, 2009 at the ISSWSH Conference, details about the LibiGel clinical development program and details about current prescribing practices of physicians who treat Hypoactive Sexual Desire Disorder (HSDD) and the need for an FDA approved pharmaceutical product for the treatment of HSDD in the U.S.

According to a research survey commissioned by BioSante among practicing gynecologists and general practitioners, 80 percent of physicians believe there is a need or great need for an FDA approved treatment for women who suffer from HSDD, for which there is no FDA approved prescription product today. The majority of physicians surveyed currently prescribe testosterone to women “off-label,” which means they prescribe testosterone for women even though currently it is not approved for this use. A significant majority of the physicians said they would switch patients to an FDA approved treatment and would prescribe an FDA approved treatment for new patients not currently being treated for HSDD. According to IMS Health, there were approximately two million testosterone prescriptions written off-label in the U.S. for women in 2007. This number of off-label prescriptions does not include “compounded” testosterone for women which could total an additional million prescriptions.

BioSante is in Phase III development of LibiGel for the treatment of HSDD in menopausal women under an FDA approved SPA (Special Protocol Assessment). BioSante is enrolling women in three Phase III clinical trials with a new drug application (NDA) planned for late 2010. “We believe LibiGel is the only product in active development for HSDD in menopausal women, and we hope to be first to market for this potential multi-billion dollar indication,” said Stephen M. Simes, BioSante’s president & CEO.

The annual ISSWSH conference brings together doctors, other healthcare providers, researchers, investors and companies in a meeting dealing with all issues related to women’s sexual health including HSDD.
