Merck's investigative AIDS drug raltegravir -- sold as Isentress -- did as well as the standard of care treatment for new patients, say U.S. doctors.
About 90 percent of all the patients treated with either raltegravir of efavirenz -- marketed as Sustiva -- were able to suppress HIV to undetectable levels.
In a report at the 4th International AIDS Society Conference on HIV Pathogenesis, Treatment and Prevention in Sydney, Martin Markowitz, clinical director of the Aaron Diamond AIDS Research Center in New York, said that treatment with raltegravir -- awaiting approval by the U.S. Food and Drug Administration -- caused fewer adverse side effects in the patients during the 48-week trial.
Markowitz also told United Press International that treatment with raltegravir resulted in a faster reduction of virus than with efavirenz.
