LINCOLNSHIRE, Ill. - November 29, 2011 (Investorideas.com newswire) - BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX) today announced the issuance of a new U.S. patent covering the �method of use� of LibiGel (testosterone gel) for treating female sexual dysfunction (FSD) and hypoactive sexual desire disorder (HSDD). The patent covers methods for treating FSD and HSDD and also includes using a metered dosage device to deliver the defined dose of the testosterone formulation in LibiGel. U.S. Patent No. 8,067,399, which issued today, will expire on December 29, 2028. The two named inventors of this new patent are a current and a former employee of BioSante.
"We are very pleased that this new LibiGel patent has issued. The patent protects the use of LibiGel in treating FSD and HSDD, and the bottle we used in our clinical work, as well as in the intended commercial product, and extends our patent protection to the end of 2028,� said Stephen M. Simes, BioSante president and CEO. �Our objective has been to continue to strengthen our intellectual property covering LibiGel and this patent is a major achievement in that direction."
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, approximately half of whom were taking concomitant estrogen therapy and half of whom took no concomitant estrogen 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 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 5,100 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 efficacy trials and the safety study, 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.
