BPA Biosante Pharmaceuticals

BioSante Pharmaceuticals, Inc. (AMEX:BPA) today reported its June 30, 2007 cash balance and its financial results for the second quarter and six months ended June 30, 2007. The Company�s cash, cash equivalents and short-term investments as of June 30, 2007 were approximately $31.3 million, as compared to approximately $11.5 million on December 31, 2006. The increase in cash is due to the private placement of 3,054,999 shares of common stock at a purchase price of $6.00 per share. The placement included, for each share purchased, a warrant to purchase 0.25 shares of common stock at an exercise price of $8.00. The net proceeds from this placement were approximately $17.3 million. The Company�s cash burn rate is expected to increase in the second half of 2007 to approximately $850,000 per month as its LibiGel� program progresses. BioSante incurred a net loss of approximately $2.4 million or ($0.10) per share for the quarter ended June 30, 2007 and $4.2 million or ($0.18) per share for the six months ended June 30, 2007, compared to a net loss of $2.2 million or ($0.17) per share and $5.5 million or ($0.28) per share for the same periods in 2006. This decrease was due primarily to a reduction in business development and legal expenses and a decrease in non-cash stock-based compensation expense. Recent Product Development Highlights Hormone Therapy In June 2007, Elestrin� (estradiol gel) was launched in the U.S. for the treatment of hot flashes by Bradley Pharmaceuticals, Inc. (NYSE:BDY), BioSante�s U.S. marketing licensee. Elestrin was approved by the U.S. Food and Drug Administration (FDA) in December 2006. Upon execution of the marketing agreement with Bradley in November 2006, BioSante received $3.5 million. The December FDA approval triggered a payment of $10.5 million to BioSante. In March 2007, the Company received $7.0 million of this payment with the balance to be received by year-end 2007. Sales-based milestone payments could bring payments from Bradley to BioSante up to an additional $40 million over several years. In addition, Bradley has agreed to pay to BioSante royalties on sales of Elestrin. Also in June 2007, the Company announced that it and a subsidiary of Teva Pharmaceutical Industries Ltd., will reinitiate their development of a male testosterone therapy product for the U.S. market. In May 2007, the Company announced an exclusive license agreement with Pantarhei Bioscience for the development and marketing of an oral contraceptive in the United States. In June 2007, the Company announced that it and Pantarhei have begun a Phase II clinical trial of an oral contraceptive. The Phase II study, being conducted in the Netherlands, will include approximately 72 women in a double-blind, placebo controlled, randomized, comparative 2-way crossover study to determine the effect of a new patented oral contraceptive on sexual arousability and the vascular component of the sexual arousal response in women. Calcium Phosphate Nanotechnology In July 2007, the Company announced new positive results for its calcium phosphate nanotechnology (CaP) as an adjuvant for a bird flu vaccine. The data indicate that a significantly lower dose bird flu vaccine may be possible based on CaP�s adjuvanting ability. Also in July 2007, the Company announced positive pre-clinical results using CaP as a potential wrinkle filler in cosmetic medicine. BioSante previously signed an option and license agreement with Medical Aesthetics Technology Corporation for use of CaP in aesthetic medicine. About BioSante Pharmaceuticals, Inc.
