LINCOLNSHIRE, Ill.--(BUSINESS WIRE)--BioSante Pharmaceuticals, Inc. (NASDAQ:BPAX) today announced that it has received commitments from three institutional investors to purchase $12 million of securities in a registered direct offering. BioSante expects to receive net proceeds of approximately $11.1 million after deducting placement agent fees and other offering expenses. BioSante has entered into securities purchase agreements with these investors pursuant to which BioSante has agreed to sell an aggregate of 6 million shares of its common stock and warrants to purchase up to 2.4 million additional shares of its common stock. Each unit, consisting of one share of common stock and a warrant to purchase 0.4 of a share of common stock, will be sold for a purchase price of $2.00.

“We are pleased to welcome new institutional investors to BioSante”

"We are pleased to welcome new institutional investors to BioSante," said Stephen M. Simes, BioSante's president and chief executive officer. “We look forward to using the proceeds from this offering to continue our LibiGel^® Phase III clinical study program. Our objective continues to be to submit a new drug application (NDA) to the U.S. Food and Drug Administration (FDA) by mid 2011. LibiGel remains the only pharmaceutical product in the U.S. in active development for the treatment of hypoactive sexual desire disorder (HSDD) in menopausal women and we continue to believe that LibiGel has the potential to be the first product approved by the FDA for this common and unmet medical need.”

All of the securities were offered pursuant to an effective shelf registration statement.
