New Analysis of WHI Data Shows Reduced Levels of Coronary Artery Calcification, in Women aged 50-59 taking Estrogen Therapy, a Predictor of Cardiovascular Events

LINCOLNSHIRE, Illinois (June 21, 2007) – BioSante Pharmaceuticals, Inc. (AMEX: BPA) today provides comment on the Women’s Health Initiative (WHI) Coronary Artery Calcium Study published today in The New England Journal of Medicine (NEJM). The study found that younger menopausal women (aged 50-59) who received a standard dose of estrogen therapy had significantly less coronary artery calcification at the end of the study period compared with those taking placebo. Coronary artery calcification is a marker of plaque in the arteries and a predictor of future cardiovascular events.

These findings are consistent with a recent re-analysis of pooled estrogen alone and estrogen plus progestin data from the WHI study, published April 4, 2007, in the Journal of the American Medical Association (JAMA). This study found no apparent increase in coronary heart disease for women who initiated hormone therapy within 10 years of menopause; and a statistically significant reduction in total mortality among women aged 50-59 in the group receiving hormone therapy compared with those in the placebo group.

“Recent analysis of the data from the WHI study have consistently clarified the initial data, to show that in the younger population of menopausal women, estrogen therapy is shown to be not only safe, but from a cardiovascular standpoint actually prove to be protective,” said Stephen M. Simes, president & CEO of BioSante. “These data should aid in the decision process in newly menopausal women seeking treatment for their symptoms,” Simes continued.

The authors conclude, “Hormone therapy should not be initiated (or continued) for the express purpose of preventing cardiovascular disease in either younger or older postmenopausal women.” The authors further state, “The current recommendations from many organizations that hormone therapy be limited to the treatment of moderate to severe menopausal symptoms, with the lowest effective dose used for the shortest duration necessary, remain appropriate.”

Elestrin, developed by Biosante and marketed by Bradley Pharmaceuticals (NYSE: BDY) provides the lowest dose of estradiol for the treatment of hot flashes, currently available.
