Use of Integrase Inhibitors in HIV-Infected Children and Adolescents

Resistance to antiretroviral drugs is an increasingly prevalent challenge affecting both the adult and pediatric HIV-infected populations. Though data on the safety, pharmacokinetics, and efficacy of newer antiretroviral agents in children typically lags behind adult data, newer agents are becoming available for use in HIV-infected children who are failing to respond to or are experiencing toxicities with traditional antiretroviral regimens. Integrase strand transfer inhibitors are one such new class of antiretrovirals. Raltegravir has been US Food and Drug Administration (FDA) approved for use in patients over the age of 4 weeks. Elvitegravir is a second member of this class, and has the potential for use in children but does not yet have a Pediatric FDA indication. Dolutegravir, a second-generation integrase inhibitor, is approved for those older than 12 years. This review summarizes the use of integrase inhibitors in children and adolescents, and highlights the results of recent clinical trials.
