F Jay How long do Phase 1 Trials generally take ? Seems like this should be due any day now. ANTEX BIOLOGICS TO BEGIN CLINICAL TRIAL ON HELICOBACTER VACCINE Gaithersburg, MD, November 15, 1996 - Antex Biologics (Nasdaq:ANTX) today announced that the U.S. Food and Drug Administration (FDA) approved the initiation of a clinical study under an Investigational New Drug (IND) Application for an orally administered Helicobacter pylori vaccine for the prevention of peptic ulcers, gastritis and other related disorders. This randomized double-blinded Phase I clinical trial will be composed of approximately 40 volunteers and will determine the safety and immunogenicity of the Company's vaccine. The vaccine consists of whole killed H. pylori cells in combination with a mucosal adjuvant. "In addition to testing for safety and immunogenicity, data obtained from this Phase I trial may confirm the H. pylori vaccine's efficacy as demonstrated by preclinical studies," said Dr. Vic Esposito, Chairman and CEO of Antex. "We are looking towards this trial to provide evidence that our vaccine will be useful as a prophylactic and potential therapeutic treatment of H. pylori disorders in humans." H. pylori is a common bacterial pathogen of humans worldwide. In developing countries, it is estimated that 100% of children 3 years or older are carriers of this pathogen. H. pylori is the major cause of chronic active gastritis and peptic ulcer disease and a risk factor for gastric cancer. Infection also increases the risk of other diseases including persistent diarrhea. "As there is no preventive treatment for H. pylori, this approval for a major clinical trial for an H. pylori vaccine is a significant achievement for the Company," said Dr. Esposito. "This vaccine, our third to enter clinical studies, demonstrates the continued progress of Antex's programs and further validates the power of the Company's core technologies in developing preventive treatment," said Dr. Esposito.
