The Pfizer Inc. AIDS drug maraviroc helps thwart the HIV virus in nearly half of people who have developed resistance to other treatments, according to two related studies published on Wednesday.
At least 42 percent of patients in Europe, North America and Australia who took maraviroc once or twice a day on top of standard drug cocktails had blood virus counts below levels that cause visible damage to the immune system.
Only 18 percent of patients who got a placebo plus a standard HIV drug combination got their viral levels that low over the 48 weeks that have been studied so far.
