BioSante Pharmaceuticals Reports Product Development Highlights
and Third Quarter 2005 Financial Results

LINCOLNSHIRE, Illinois (November 10, 2005) –BioSante Pharmaceuticals, Inc. (AMEX: BPA) today reported product development highlights and financial results for the third quarter ended September 30, 2005.

“We achieved milestones across our key clinical programs this quarter. We presented positive Phase III data for Bio-E-Gel^™, licensed three patents that cover the use of testosterone (LibiGel™) to treat hypoactive sexual desire disorder in women on hormone contraception, and entered into an allergy licensing option agreement for our CaP nanotechnology,” said Stephen M. Simes, BioSante’s president and chief executive officer. “We continue to prepare our New Drug Application for Bio-E-Gel. Regarding LibiGel, we are using recent updated guidance from the FDA for testosterone-based products in defining our Phase III protocols, and expect to initiate Phase III clinical studies of LibiGel in the first quarter of 2006.”

Product and Corporate Highlights

	•		BioSante presented Phase III clinical data on Bio-E-Gel (bio-identical estradiol gel) at the North American Menopause Society (NAMS) annual meeting in San Diego. Results from the 484-patient study identified three effective doses as well as the lowest effective dose. In the study, Bio-E-Gel significantly decreased the number of hot flashes by 88 percent, from 12.9 per day at baseline to 1.6 after treatment (p<0.0001). The decrease was also significant versus placebo, with a mean decrease of 11.3 hot flashes per day with Bio-E-Gel versus a decrease of 6.1 with placebo (p<0.0001). Bio-E-Gel produced low estradiol blood levels and had a safety profile similar to that observed in the placebo group. Notably, there was minimal application site irritation reported, a side effect known to be associated with transdermal patches.
	•		BioSante signed a worldwide license agreement with Wake Forest University Health Sciences and Cedars Sinai Medical Center covering three patents encompassing triple hormone contraception technology, a novel combination of estrogens and progestins with androgens. BioSante plans to study LibiGel (bioidentical testosterone gel) as the androgen component to help restore sexual desire and activity to women taking traditional oral contraceptives who have experienced this side effect. Financial terms include regulatory milestone payments, maintenance payments and royalty payments if a product incorporating the licensed technology is approved and subsequently marketed. In a Phase II study of LibiGel in surgically menopausal women, LibiGel was shown to increase the number of satisfying sexual events by 238 percent. This increase was statistically significant compared to baseline and placebo.

In September, BioSante signed a Material Transfer and Option Agreement for an exclusive option to obtain a license to use BioSante’s calcium phosphate nanotechnology (CaP) in the development of a series of allergy products. The undisclosed European partner company will fund its development of potential products for the treatment of conditions including rhinitis, asthma, conjunctivitis, dermatitis, and allergic gastrointestinal diseases. BioSante received a non-refundable $250,000 upfront payment, and could potentially receive more than $10 million dollars in additional maintenance, milestone and royalty payments if the option is exercised and the parties enter into an exclusive license agreement.
