BioSante Pharmaceuticals Announces New LibiGel® Phase III Efficacy Trials
Published on Monday, 11 June 2012 06:07 Written by TradersHuddle StaffLINCOLNSHIRE, Ill.-( Business Wire )-
BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX), announced today that the Company plans to initiate two new LibiGel Phase III efficacy trials. This decision is based on an extensive analysis of previous efficacy data, consultation with key opinion leaders (KOLs) in female sexual dysfunction, testosterone therapy and placebo effects, as well as a meeting with the U.S. Food and Drug Administration (FDA). BioSante also intends to continue the on-going LibiGel Phase III cardiovascular and breast cancer safety study as per protocol. LibiGel (testosterone gel) is in development for the treatment of female sexual dysfunction (FSD), specifically, hypoactive sexual desire disorder (HSDD) in menopausal women.
The protocol for the two new efficacy trials is in development, and BioSante intends to provide additional trial design information and timing of trial initiation once finalized. BioSante also intends to apply for an FDA Special Protocol Assessment (SPA) agreement prior to initiating the efficacy trials. Currently, it is expected that the efficacy trials will include the same FDA-required efficacy endpoints as prior Phase III efficacy trials: an increase in the number of satisfying sexual events and sexual desire, and decreased distress associated with low desire.
“We continue to believe that HSDD is an important unmet medical need for women and that LibiGel can provide a meaningful treatment option,” said Stephen M. Simes, BioSante’s president & chief executive officer. “In addition, the ongoing LibiGel Phase III safety study, the largest testosterone trial of its kind, has accumulated over 6,500 women-years of data to support the safety of LibiGel. It is our intention to conduct the primary analysis of the safety study in the second half of 2012.”
Phillip Donenberg, BioSante’s senior vice president of finance and chief financial officer added, “Our cash balance of $49.5 million on March 31, 2012 puts us in a strong financial position to launch this new LibiGel strategy. We are committed to the continued development of LibiGel and to maximizing value for our stockholders.”
As announced on December 14, 2011, the Company’s previous LibiGel Phase III efficacy trials indicated that LibiGel increased satisfying sexual events and sexual desire and decreased distress. However, the placebo response in the two previous efficacy trials was greater than expected; therefore, LibiGel’s results were not shown to be statistically different from placebo. BioSante is committed to ensuring that the design of the new Phase III efficacy trials addresses the higher than expected placebo response observed in the prior trials.
Conference Call and Webcast Information
A conference call and webcast will be held today at 8:30 a.m. EDT to discuss the new LibiGel Phase III efficacy trials strategy. Interested parties may join the call from within the U.S. by dialing (877) 407-8031; outside the U.S., dial +1-201-689-8031.

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). Two Phase III efficacy trials of LibiGel have been completed and a cardiovascular (CV) events and breast cancer study that has completed enrollment of 3,656 subjects is ongoing. The two completed efficacy trials were double-blind, placebo-controlled trials that enrolled over 500 surgically menopausal women each for six-months of therapy. In the two completed Phase III efficacy trials, LibiGel performed as predicted based on previous experience with testosterone products for FSD, including an increase in satisfying sexual activity and sexual desire and a decrease in distress. However, the placebo response in the two efficacy trials was greater than expected; and therefore, LibiGel’s results were not shown to be statistically different from placebo. The completed efficacy trials were conducted according to an FDA 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.
About the LibiGel Phase III Cardiovascular and Breast Cancer Safety Study
The Phase III LibiGel safety study is a randomized, double-blind, placebo-controlled, multi-center, cardiovascular (CV) events and breast cancer study that has completed enrollment of 3,656 subjects. 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, for example, hypertension and diabetes. The objective of the safety study is to show 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. BioSante intends to conduct the primary analysis of the safety study in the second half of 2012.
