BioSante Pharmaceuticals Announces 2004 Key Achievements and Financial Results

LINCOLNSHIRE, Illinois (March 28, 2005) – BioSante Pharmaceuticals (Amex: BPA) today announced key achievements and financial results for the year ended December 31, 2004.
‹We continued to make important progress throughout the year in our late stage hormone therapy clinical programs and CAP nanotechnology,Š commented Stephen M. Simes, BioSante‰s president and chief executive officer. ‹We expect our efforts to result in a new drug application filing with the FDA for Bio-E-Gel® and the initiation of our Phase III development program for LibiGel® in 2005.Š

Highlights for the last 15 months include:

Hormone Therapy Achievements

  • Completed enrollment in our pivotal Phase III clinical trial of Bio-E-Gel (bioidentical estradiol gel).
  • Reported positive results of the completed Phase II clinical trial of LibiGel (bioidentical testosterone gel) for treatment of female sexual dysfunction (FSD) significantly increasing (238%) the number of satisfying sexual events.

CAP Nanotechnology Achievements

  • Product developments:
    — Received notice of allowance from the European Patent Office (EPO) accepting BioSante’s patent application for the manufacturing process of the company’s unique calcium phosphate nanoparticles (CAP).
    — Positive pre-clinical results for intranasally administered BioVantœ/anthrax vaccine, compared to an Alhydrogel/anthrax vaccine or the antigen alone.
    — Positive results in animal models for the sustained-release delivery of therapeutic proteins, including long-acting buccal delivery of insulin.
  • 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 non-injected biodefense vaccines including anthrax, ricin, staph and bubonic plague.
    — DynPort: U.S. Department of Defense subcontract for evaluation and development of a non-injected anthrax vaccine.

Financial Achievements

  • Raised new capital in a $17.7 million ($16.4 million net of transaction costs) common stock/warrant placement.
  • Closed the year with $17.3 million in cash, cash equivalents and short-term investments.

BioSante incurred a net loss of approximately $12.0 million or ($0.70) per share for the year ended December 31, 2004, compared to a net loss of $6.0 million or ($0.54) per share for the same period in 2003. The increase in the net loss is largely the result of increased research and development expenses incurred primarily as a result of (i) completing the Phase II LibiGel trial, and (ii) conducting the Phase III Bio-E-Gel trial. The company‰s cash, cash equivalents and short-term investments as of December 31, 2004 were approximately $17.3 million, compared to $9.1 million at December 31, 2003.
