BioSante Pharmaceuticals Reports Product Development Highlights and 2007 Financial Results

(Nanowerk News) BioSante Pharmaceuticals, Inc. (NASDAQ: BPAX) announced today product development and financial results for the year ended December 31, 2007.
“BioSante has had an exciting year and that excitement continues,” said Stephen M. Simes, BioSante’s president and chief executive officer. “We have made significant advances with the products in our pipeline, in particular with regard to LibiGel®, our transdermal testosterone gel for the treatment of female sexual dysfunction (FSD). We reached agreement with the U.S. Food and Drug Administration (FDA) on a Special Protocol Assessment (SPA) that sets in motion a process by which we are pursuing aggressively the Phase III clinical development of LibiGel. This SPA establishes the parameters of the clinical trial design that can lead to regulatory approval. The SPA agreement also effectively establishes that FSD, specifically hypoactive sexual desire disorder (HSDD), is a medical condition for which therapeutic remedies can apply.”
Product Achievements
  • In February 2007, BioSante received notice of allowance in the United States of a patent covering the formulation used in Elestrin™, its FDA approved estradiol gel, and LibiGel, our testosterone gel, in Phase III development.
  • In June 2007, BioSante and a subsidiary of Teva Pharmaceutical Industries Ltd. (NASDAQ: TEVA) signed an amendment to its development and license agreement under which Teva and BioSante reinitiated the development of Bio-T-Gel™, a male testosterone therapy product, for the U.S. market.
  • Later in June, BioSante announced the commercial launch of Elestrin (estradiol gel). Elestrin is an effective, ultra-low dose transdermal estrogen therapy approved by the FDA in December 2006 for the treatment of moderate-to-severe vasomotor symptoms (hot flashes) associated with menopause. The marketing of Elestrin is done by BioSante’s marketing licensee Nycomed.
  • Also in June, BioSante announced that it and Pantarhei Bioscience B.V., a Netherlands-based pharmaceutical company, initiated a Phase II human clinical trial of a new oral contraceptive using BioSante’s patented “triple-therapy” contraceptive technology.
  • In September 2007, BioSante received clarity from and announced it is in agreement with the FDA on key FDA safety requirements for the development and approval of LibiGel in the treatment of FSD, specifically, hypoactive sexual desire disorder (HSDD).
  • In January 2008, BioSante initiated its Phase III safety study of LibiGel, as per the protocol agreed to with the FDA. The primary focus of the safety study is to evaluate the cardiovascular risk of using testosterone in women. The Phase III study protocol seeks to show the relative safety of using low-dose testosterone versus placebo in the treatment of FSD in menopausal women.
  • Later in January, BioSante completed and reached agreement with the FDA under the SPA process for its Phase III safety and efficacy clinical trials for LibiGel. The SPA process and agreement affirms that the FDA agrees that the LibiGel Phase III clinical trials design, clinical endpoints, sample size, planned conduct and statistical analyses are acceptable to support regulatory approval. Further, it provides assurance that these agreed measures will serve as the basis for regulatory review and decision by the FDA to approve a new drug application (NDA) for LibiGel.
  • CaP Nanotechnology Achievements
  • In January 2007, BioSante announced positive results of a dose ranging pre-clinical study demonstrating that its calcium phosphate (CaP) nanoparticle-based vaccine adjuvant, BioVant™, may serve as a vaccine adjuvant for the development of an effective vaccine against H5N1 avian flu, widely known as bird flu. BioSante’s pre-clinical study's objective was to determine the optimal formulation of BioVant with a very low dose of H5N1 antigen.
  • In November, BioSante announced a license agreement covering the use of CaP as a facial filler (BioLook™) in aesthetic medicine. The license was signed with Medical Aesthetics Technology Corporation (MATC) with whom BioSante has been working in the field of aesthetic medicine.
  • Financial Highlights
  • During 2007, BioSante received $10.5 million in milestone payments under the terms of its Elestrin™ licensing agreement with Nycomed. The payments were triggered by the December 2006 FDA approval of Elestrin.
  • In June, BioSante completed an $18.3 million private placement of shares of its common stock and warrants to institutional and other accredited investors. A total of 3,054,999 shares of common stock were sold at a purchase price of $6.00 per share. Investors also received warrants to purchase 763,750 shares of common stock at an exercise price of $8.00 per share.
  • In November 2007, BioSante’s common stock began trading on NASDAQ under the symbol BPAX. BioSante was formerly listed on The American Stock Exchange.
  • Financial Results for 2007
    For the year ended December 31, 2007, BioSante’s cash, cash equivalents and short-term investments were approximately $30.7 million as compared to $11.4 million at December 31, 2006. This increase was attributable to the Nycomed milestone payments for Elestrin and proceeds from the private placement. The company’s net loss was approximately $7.6 million or $(0.30) per basic and diluted share for the year ended December 31, 2007, compared to a net income of $2.8 million or $0.13 per basic and diluted share for the same period in 2006. This decrease is due to the recognition of Elestrin licensing and milestone revenue in 2006.
