Bristol-Myers Tests AIDS Drug That May Have Once-Daily Dosing Bloomberg News September 24, 1998, 11:52 p.m. ET Bristol-Myers Tests AIDS Drug That May Have Once-Daily Dosing San Diego, Sept. 24 (Bloomberg) -- Bristol-Myers Squibb Co., the second largest U.S. drugmaker by sales, said early tests suggest its experimental AIDS drug, a new member of the powerful protease inhibitor class, could be effective when taken just once a day. If this proves to be the case in more advanced testing, Bristol-Myers' drug would have a clear advantage over existing protease inhibitors made by Merck & Co., Agouron Pharmaceuticals Inc., Roche Holding AG and Abbott Laboratories. Bristol-Myers could begin testing the drug in people with HIV in 1999. It applied earlier this month to the U.S. Food and Drug Administration to start extensive testing of the new drug. Protease inhibitors can have annual sales of $400 million to $500 million. ''We're excited,'' said Richard Colonno, who leads research into new drugs for infectious disease at Bristol-Myers. ''It has the potential to be a once-a-day drug.'' Demand for such drugs is strong. DuPont Co. last week won FDA approval of the first once-a-day AIDS drug, Sustiva. So far, it has shipped more than 90,000 bottles. People infected with HIV need simpler regimens than the complex combinations, or ''cocktails,'' of existing drugs they must now take. Protease inhibitors, such as Merck's Crixivan, are taken three times a day. Common drug combinations have people swallowing handfuls of pills five times a day. Missed or improperly taken doses help HIV learn how to resist the drugs. Eventually, some treatments can lose their effectiveness, leaving people with fewer options for fighting the potentially fatal virus. Researchers will present studies on the new Bristol-Myers AIDS drug this week at the Interscience Conference on Antimicrobial Agents and Chemotherapy in San Diego. Bristol-Myers acquired the drug through an agreement with its original developer, Swiss drugmaker Novartis AG, Colonno said. Bristol-Myers also will present a study that found its experimental hepatitis drug lobucavir was more effective than the leading approved treatment, Glaxo Wellcome Plc's 3TC, Colonno said. The New York-based drugmaker also will present studies of a new antibiotic, Tequin, also known as gatifloxacin. Tequin and lobucavir are both in the last of the three stages of testing required to apply for FDA approval. --Kerry Dooley and Kristin Jensen in San Diego through the New
