The LibiGel safety study is tracking a predefined list of cardiovascular events, in agreement with the FDA, including cardiovascular death, myocardial infarction and stroke, in women 50 years of age or older and suffering from at least two cardiovascular risk factors including hypertension and diabetes. The objective of the safety study is to show the relative safety of testosterone compared to placebo in the number of cardiovascular events. The incidence of breast cancer also will be tracked over the course of the study.

In addition to the Phase III Cardiovascular and Breast Cancer Safety Study, BioSante is conducting two LibiGel Phase III efficacy trials. The Phase III efficacy trials of LibiGel in the treatment of FSD are double-blind, placebo-controlled trials that will enroll up to approximately 500 surgically menopausal women each for a six-month clinical trial. The efficacy trials are being conducted under an FDA approved SPA (special protocol assessment agreement).

As previously announced by BioSante, treatment with LibiGel in a Phase II clinical trial significantly increased satisfying sexual events in surgically menopausal women suffering from FSD. The Phase II trial 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 clinical trial was a double-blind, placebo-controlled trial, conducted in the United States, in surgically menopausal women distressed by their low sexual desire and activity.
