A Study of the Safety, Tolerability, and Antiretroviral Activity of Raltegravir (MK-0518) in Combination With Other Antiretroviral Therapies in Russian Children and Adolescents Infected With Human Immunodeficiency Virus (HIV-1) (MK-0518-248)

A Phase II, Multicenter, Open-Label, Noncomparative Study of Raltegravir (MK-0518) in Two Oral Formulations in Combination With Other Antiretroviral Agents to Evaluate the Safety, Tolerability, and Antiretroviral Activity in HIV-1 Infected Russian Children and Adolescents

This multicenter, open-label, noncomparative study evaluates two oral formulations of raltegravir (MK-0518, film-coated tablet and chewable tablet) in combination with other antiretroviral agents for safety, tolerability, and antiretroviral activity in treatment-naive or treatment-experienced Russian children and adolescents infected with human immunodeficiency virus-1 (HIV-1).

As raltegravir is indicated in combination with other antiretroviral therapies (ARTs) for the treatment of HIV-1 infection in pediatric patients in the United States (US), this study is designed to gain local treatment experience on the use

of raltegravir in the pediatric HIV-infected population in Russia.

Exclusion Criteria:

• Females pregnant or breast-feeding, or expecting to conceive or donate eggs

• History or current evidence of any condition, therapy, laboratory

abnormality, or other circumstance that might confound the results of the study, or interfere with participation for the full duration of the study

raltegravir study treatment; short courses of corticosteroids are permitted.
