Trial Outcomes & Findings for 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) (NCT NCT01717287)

NCT ID: NCT01717287

Last Updated: 2018-08-21

Results Overview

A clinical adverse experience is defined as any unfavorable and unintended change in the structure, function, or chemistry of the body temporally associated with the use of the study drug, whether or not considered related to the use of the product. Any worsening of a preexisting condition which is temporally associated with the use of the study drug is also an adverse experience.
