Safety and efficacy of enfuvirtide for 48 weeks as part of an optimized antiretroviral regimen in pediatric human immunodeficiency virus 1-infected patients.


Journal Article

BACKGROUND: Enfuvirtide is the only entry inhibitor approved for the treatment of human immunodeficiency virus (HIV)-1 infection. It is approved for use in adults and dosage recommendations exist for children aged 6 years or older. METHODS: T20-310 was a multicenter, open-label, nonrandomized, noncomparative study of the safety and efficacy of 2.0 mg/kg (maximum 90 mg) twice-daily subcutaneous enfuvirtide for 48 weeks in 52 treatment-experienced, HIV-1-infected pediatric patients (3-16 years) receiving optimized background therapy. RESULTS: Enfuvirtide was generally well tolerated, and no new patterns of adverse events compared with adults were observed. Mild-to-moderate injection-site reactions were the most common adverse event. Of those participants on treatment for 48 weeks, the median change from baseline in HIV-1 RNA was -1.17 log10 copies/mL (n = 32), and there was a median CD4 change of +106 (n = 25) cells/mm3 and +4.7 CD4%. Seventeen (32.7%) patients achieved a viral load decrease of > or =1 log10 copies/mL and 11 (21.2%) achieved HIV-1 RNA <400 copies/mL. Virologic and immunologic treatment responses were substantially better for children (<11 years) than adolescents. Steady-state mean enfuvirtide C(trough) levels were stable during 24 weeks with no differences between children and adolescents. CONCLUSIONS: Enfuvirtide is an effective treatment for HIV-1 infection in children and adolescents receiving optimized background therapy and has a favorable safety profile. Efficacy in adolescents was inferior; probably related to unique adherence challenges. The long-term safety and efficacy of enfuvirtide in pediatric patients is comparable to that observed in adults.
