BioSante Pharmaceuticals Reports

LINCOLNSHIRE, Illinois – (May 1, 2007) – BioSante Pharmaceuticals, Inc. (AMEX: BPA) today reported its March 31, 2007 cash balance and its financial results for the first quarter ended March 31, 2007.

The Company’s cash, cash equivalents and short-term investments as of March 31, 2007 were approximately $15.1 million, as compared to approximately $11.5 million on December 31, 2006. The Company’s cash burn rate in the second quarter of 2007 is expected to be approximately $750,000 per month.

BioSante incurred a net loss of approximately $1.8 million or ($0.08) per share for the quarter ended March 31, 2007, compared to a net loss of $3.2 million or ($0.17) per share for the same period in 2006. This decrease was due primarily to a reduction in business development costs and legal expenses and a decrease in non-cash stock-based compensation expense.

Recent Product Developments and Corporate Highlights

As previously announced, the Companyin December 2006 received its first U.S. Food and Drug Administration (FDA) approval for Elestrin™ (estradiol gel) in the treatment of hot flashes. The lower of the two Elestrin doses approved is the lowest dose of estradiol approved for the treatment of hot flashes. In November 2006, the Company bolstered its cash position and realized another milestone in the commercialization of Elestrin by signing an exclusive agreement with Bradley Pharmaceuticals, Inc. (NYSE: BDY) for the marketing of Elestrin in the United States. Upon execution of the agreement, 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 and the rest is 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. Bradley is planning a mid-2007 launch of the product.

In December 2006, the Company announced that it initiated a Phase III safety and efficacy trial of LibiGel® (transdermal testosterone gel) in the treatment of female sexual dysfunction (FSD). The double-blind, placebo-controlled Phase III trial will enroll surgically menopausal women for a six-month clinical trial, conducted under a Phase III protocol reviewed by and on file with the FDA.

In February 2007, the Company announced that a new patent was issued covering the formulations used in Elestrin (estradiol gel), BioSante’s newly approved treatment for moderate to severe vasomotor symptoms associated with menopause and LibiGel® (transdermal testosterone gel), which recently moved into Phase III clinical development for the treatment of female sexual dysfunction. The patent, which was issued on April 3, 2007 covering both Elestrin and LibiGel, will expire on June 25, 2022.
