WASHINGTON (AP) - Health officials repeated safety concerns about an experimental group of HIV drugs Friday, days before government advisers will recommend whether the first drug from the class merits approval.
Pfizer Inc. seeks Food and Drug Administration approval for maraviroc, potentially the first in a novel group of drugs to fight HIV, the virus that causes AIDS. Pfizer proposes marketing maraviroc as Celsentri.
Pfizer believes there is a clear unmet need for new drugs to fight HIV in patients for whom other, older drugs no longer work. Celsentri is unlike any other HIV medicines now on the market in that it targets the cells of patients and not the virus itself.
