Labeled uses

SELZENTRY, in combination with other antiretroviral agents, is indicated for adult patients infected with only CCR5-tropic HIV-1. This indication is based on analyses of plasma HIV-1 RNA levels in two controlled studies of SELZENTRY in treatment-experienced subjects and one study in treatment-naïve subjects. Both studies in treatment-experienced subjects were conducted in clinically advanced, 3-class antiretroviral-experienced (NRTI, NNRTI, PI, or enfuvirtide) adults with evidence of HIV-1 replication despite ongoing antiretroviral therapy. The following points should be considered when initiating therapy with SELZENTRY: Adult patients infected with only CCR5-tropic HIV-1 should use SELZENTRY. Tropism testing must be conducted with a highly sensitive tropism assay that has demonstrated the ability to identify patients appropriate for SELZENTRY use. Outgrowth of pre-existing low-level CXCR4- or dual/mixed-tropic HIV-1 not detected by tropism testing at screening has been associated with virologic failure on SELZENTRY. [see Microbiology (12.4) Clinical Studies (14.3) ] . Use of SELZENTRY is not recommended in subjects with dual/mixed or CXCR4-tropic HIV-1 as efficacy was not demonstr…
