Exhibit 99.1 [BIOSANTE LOGO] BIOSANTE PHARMACEUTICALS, INC. 111 Barclay Boulevard Linconshire, Illinois 60069 www.biosantepharma.com ================================================================================ FOR IMMEDIATE RELEASE AMEX: BPA BIOSANTE PHARMACEUTICALS ANNOUNCES 2003 KEY ACHIEVEMENTS AND FINANCIAL RESULTS LINCOLNSHIRE, ILLINOIS (MARCH 9, 2004) -- BioSante Pharmaceuticals (Amex: BPA) today announced key achievements and financial results for the year ended December 31, 2003. "We are quite pleased with our achievements and progress in the last year. Recent FDA actions and hormone therapy market indications are very encouraging," said Stephen M. Simes, president and chief executive officer of BioSante. "The most exciting recent event affecting the estrogen market is the FDA's approval of an estrogen gel developed by Solvay Pharmaceuticals, Inc. The approval indicates that the FDA is willing to approve new estrogen products and specifically estrogen gel products. Moreover, in light of recently reported safety data from the Women's Health Initiative studies of orally administered estrogen products, all of the hormone therapy products we are developing are expected to offer important safety advantages because of their transdermal route of administration and their use of bioidentical estradiol and testosterone. "We expect Solvay's approval to help increase the size of the transdermal segment of the estrogen market, which is now about $300 million," Simes continued. "Our goal is to be the next gel to market and to capture a significant share of the large and valuable transdermal estrogen segment. This year we will continue to aggressively develop our late-stage hormone therapy products as well as pursue additional government grants and contracts for development of our nanotechnology-based vaccine adjuvant and delivery system and protein delivery technologies." Highlights for the last 14 months include: Hormone Therapy Achievements o Announced licensing agreement with TEVA Pharmaceuticals for development and marketing of a hormone therapy product; TEVA-managed development continues. o Completed Phase II/III clinical trial of Bio-E-Gel(TM) for post-menopausal symptoms and identified effective dose of Bio-E-Gel.

o Initiated pivotal Phase III trial of Bio-E-Gel representing the last stage before submission to the FDA. o Initiated a Phase II clinical trial of LibiGel(TM) for treatment of female sexual dysfunction; reported on positive blinded interim results indicating increases in sexual desire and numbers of sexual events. "Proctor and Gamble has indicated publicly that they will spend $100 million on launch of their testosterone patch in development for female sexual dysfunction," said Simes. "Our objective is to be the first testosterone gel to market in order to maximize our share of what is estimated to be a multi-billion dollar market." CAP Nanotechnology Achievements o Product developments: -- Positive results in several animal models using BioSante's calcium phosphate nanotechnology (CAP) as a safer vaccine adjuvant to improve the efficacy of vaccines versus no adjuvant and versus alum, the only FDA approved vaccine adjuvant. -- Positive results in animal models for the sustained-release delivery of therapeutic proteins, including long-acting injectable insulin, inhaled insulin and oral insulin, among other proteins tested. o Current product development agreements: -- U.S. Navy: Cooperative Research and Development Agreement (CRADA) for evaluation and development of a malaria vaccine. -- U.S. Army: CRADA for evaluation and development of needle-free biodefense vaccines including anthrax, ricin, staph and bubonic plague. -- DynPort: U.S. Department of Defense subcontract ($658,000) for evaluation and development of a needle-free anthrax vaccine. -- NIH: SBIR grant ($100,000) for oral insulin development. Financial Achievements o Raised new capital in a $10.3 million private common stock/warrant placement. o Common stock listed on the American Stock Exchange. BioSante incurred a net loss of approximately $6.0 million or ($0.54) per share for the year ended December 31, 2003, compared to a net loss of $3.8 million or ($0.51) per share for the same period in 2002. The overall increase in the net loss is largely the result of the receipt in 2002 of approximately $2.5 million in licensing revenues associated with BioSante's hormone therapy products, which did not

recur in 2003. The company's cash balance as of December 31, 2003 was approximately $9.1 million, compared to $4.9 million at December 31, 2002. "We are pleased with the progress made in 2003 and we are off to a promising start this year," Simes said. "We have made great strides toward the development of important new hormone therapies, vaccines and oral delivery, and are well positioned for meeting our key objective of substantial growth in stockholder value in the months and years ahead."
