National News UNITED STATES: \"Tanox to Report Promising Results for AIDS Drug\" back to top Wall Street Journal, (10.26.2005) Marilyn Chase The Houston-based biotechnology firm Tanox Inc. is expected today to report encouraging results from an ongoing Phase II safety and efficacy study of its intravenous HIV entry inhibitor drug TXN-355. Designed to block entry into human cells by both X4 and R5 classes of HIV, TXN-355 lowered HIV levels in blood better than a placebo in 82 patients in the trial, with only mild adverse drug reactions reported so far, said Tanox. Patients in both control and TXN-355 groups also received a standard AIDS drug cocktail. TXN-355 is created from the natural infection-fighting monoclonal antibodies of mice; these are genetically engineered to lose their mouse qualities and behave like human antibodies. R5 and X4 viruses use different portals to enter cells; Tanox said the dual-class blocking TXN-355 represents \"a major advantage\" over drugs that block HIV from infecting cells through one portal only. Granted fast-track status by the Food and Drug Administration, TXN-355 could be used for a broad class of HIV patients, including those with HIV resistant to multiple drugs, said Stanley Lewis, Tanox medical director. After completion of the current trial, Tanox plans to begin a final Phase III study next year, said Lewis, adding that the drug could be on the market as early as 2009. NEVADA: \"Nevada Board to Consider Pharmacist Conscience Rules\" back to top Associated Press, (10.23.2005) On Thursday, the Nevada Board of Pharmacy will consider a controversial proposal that would permit pharmacists in the state to refuse to fill a prescription that violated their moral or religious beliefs. Under the proposed regulation, pharmacists could refuse a prescription if they notify their employer in writing in advance, arrange \"without delay\" for another pharmacist to fill the prescription, and decline to discuss the reason for refusing the prescription. An attempt earlier this year in the Legislature to pass the regulation was defeated. |
