Selzenttry (maraviroc) by FDA [MUY IMPORTANTE MODIFICACIÓN]

On November 20, 2009, the Food and Drug Administration approved a supplemental NDA to expand the indication for Selzenttry (maraviroc) to include combination antiretroviral treatment of therapy naïve adults infected with CCR5-tropic HIV-1 virus. Maraviroc was previously approved (8/6/2007) for treatment of therapy experienced adult patients infected with CCR5-tropic HIV-1 virus. The expanded indication is based upon data collected through 96 weeks from Study A4001026, demonstrating safety and efficacy.
The new label can be found on the FDA website at Drugs@FDA.
The following changes were made to the labeling:
