BPA Biosante Pharmaceuticals

BioSante Pharmaceuticals (AMEX:BPA) today reported on certain product development highlights and announced financial results for the second quarter ended June 30, 2005. "Our positive topline data from the Bio-E-Gel(TM) Phase III trial and progress made with our CaP nanotechnology program drove this successful quarter for BioSante," said Stephen M. Simes, BioSante's president and chief executive officer. "We plan to present full Bio-E-Gel data at a medical meeting this fall, with publication in a peer-reviewed journal to follow. Currently, we are preparing a New Drug Application for submission to the U.S. Food and Drug Administration for Bio-E-Gel, and anticipate initiating Phase III LibiGel(TM) studies by year end." Product and Corporate Highlights -- BioSante announced significant safety and efficacy results of its 12-week, randomized, double-blind, placebo-controlled Phase III clinical trial of Bio-E-Gel (bioidentical estradiol transdermal gel) for the treatment of moderate-to-severe hot flashes in menopausal women. The 484-patient study, which included three doses of Bio-E-Gel to maximize the safety profile by identifying the lowest effective dose, had four co-primary endpoints of a significant decrease over placebo in both the number and severity of hot flashes at Week 4 and Week 12 of treatment. By Week 4, the mid and high doses of Bio-E-Gel showed highly significant decreases in the number and severity of hot flashes versus placebo (p less than 0.0001), a response that was maintained until Week 12. At Week 5, the low dose showed a highly significant decrease in the number (p less than 0.001) and severity (p less than 0.01) of hot flashes verses placebo. These significant responses were maintained through Week 12 (p less than 0.0001), therefore suggesting identification of the lowest effective dose. There were no significant differences in the safety profile of any dose of Bio-E-Gel compared to placebo. -- The Company presented a review of progress toward the use of BioVant(TM), BioSante's patented calcium phosphate (CaP) nanoparticle technology, in viral and bacterial vaccine candidates at the International Conference on Immunopotentiators in Modern Vaccines in Spain. BioSante also presented BioVant data at the annual World Vaccine Congress in Montreal, focusing on the intranasal mucosal surface delivery of an anthrax vaccine, and highlighting the simultaneous immune adjuvant effects and non-injected vaccine delivery potential of BioVant. -- BioSante announced a new manufacturing agreement with a U.S.-based current good manufacturing practices (cGMP) manufacturer for large-scale quantities of CaP nanotechnology. -- BioSante was added to the Russell Microcap(TM) Index, which measures the performance of the microcap segment and includes the smallest 1,000 securities in the small-cap Russell 2000 Index plus the next 1,000 securities, based on descending market capitalization.
