We have entered into a clinical trial agreement with the National Institutes of Allergy and Infectious Diseases, a division of the National Institutes of Health, commonly referred to as - 11 - <PAGE> 13 NIH, to conduct a Phase 2 trial of CTV-05, a proprietary biotherapeutic agent for the treatment of bacterial vaginosis, or BV. BV, the most common gynecological infection in women of childbearing age, is an imbalance of naturally occurring organisms in the vagina. Bacterial Vaginosis BV develops when certain bacteria normally present in the vagina in low levels multiply to infectious levels. BV is associated with serious health risks such as pelvic inflammatory disease, pre-term birth, post-surgical infection and an increased susceptibility to sexually transmitted diseases, including AIDS. The standard treatments currently prescribed for BV are oral or topical antibiotics including metronidazole and clindamycin. These treatments are not optimal, having significant recurrence rates. Moreover, antibiotic use depletes a beneficial bacteria called lactobacilli. CTV-05: Rationale, Product Profile and Clinical Studies A healthy vagina is principally populated by lactobacilli. The presence of lactobacilli in the vagina, particularly those that produce hydrogen peroxide which is active against disease causing bacteria, has been linked to decreased incidence of BV and other urinary tract and gynecological infections. However, many women lack sufficient populations of hydrogen peroxide-producing lactobacilli to maintain vaginal health, making them more susceptible to infection. Studies have shown that the CTV-05 strain of lactobacillus is able to restore the natural balance of the bacteria in the vagina and produce both hydrogen peroxide and lactic acid, substances which are active against disease-causing bacteria and serve a protective role. Because of this, CTV-05 has the potential to improve cure rates when used in conjunction with approved antibiotics, to prevent BV recurrence and thus to reduce serious health risks. In the Phase 2 safety and efficacy trial, funded by National Institute of Health, CTV-05 is administered topically to BV patients. The study is primarily designed to show whether CTV-05 improves cure rates of BV at 30 days. The study is the first large trial to look at recurrence rates of BV at 90 days. To date, we have enrolled over 200 patients in a 400 patient trial at three sites and expect to conclude the trial in 2001. Other Indications Recently completed studies by GyneLogix under a Center for Disease Control and Prevention grant, have shown that CTV-05 is active against the organisms which cause yeast infections and gonorrhea. We plan to conduct pilot clinical studies in these indications. IS-159 In 1998, we acquired from Immunotech S.A. exclusive worldwide rights to IS-159, a selective chemical that reacts with receptors found on cerebral blood vessels and nerve terminals. We are seeking a collaborator to develop IS-159 and do not intend to initiate further studies of IS-159 until we enter into a collaborative arrangement. PRODUCT ACQUISITION STRATEGY We plan to continue to acquire, develop and commercialize late-stage product candidates or approved products that make a clinical difference to patients managed by focused groups of medical decision-makers. Our strategy is to acquire late-stage development product candidates with an anticipated time to market of four years or less and existing clinical data which provides reasonable evidence of safety and efficacy. In addition, we aim to acquire approved products that can be marketed by our commercial organization. In making our acquisition decisions we attempt to select products that meet these criteria and achieve high investment returns by: - understanding the market opportunity for initially-targeted uses of the drug; - assessing the investment and development programs that will be necessary to achieve a marketable product profile in these initial uses; and - attempting to structure the design of our development programs to obtain critical information relating to the clinical and economic performance of the product early in the development process, so that we can make key development decisions. To date, we have implemented this strategy with Angiomax, CTV-05 and IS-159. - 12 - <PAGE> 14 We intend to acquire products and product candidates with possible uses and markets beyond those on which our initial investment program will be focused. We plan to acquire other products that will enhance the acute hospital product franchise we are building around Angiomax. We are also seeking other specialty anti-infective products and product candidates that will fit into the franchise we expect to build around CTV-05. We have assembled a management team with significant experience in drug development and in drug product launches and commercialization.<< Cheers, Tuck
