A Study to Evaluate the Safety and Efficacy of Raltegravir (MK0518) in HIV-Infected Patients Failing Current Antiretroviral Therapies (MK0518-018 EXT2)
A Multicenter, Double-Blind, Randomized, Placebo-Controlled Study to Evaluate the Safety and Antiretroviral Activity of MK-0518 in Combination With an Optimized Background Therapy (OBT), Versus Optimized Background Therapy Alone, in HIV-Infected Patients With Documented Resistance to at Least 1 Drug in Each of the 3 Classes of Licensed Oral Antiviral Therapies

Double-Blind Extension - Week 156: Percentage of Participants Without Loss of Virologic Response
Tidsramme: 156 weeks
|
For participants with confirmed HIV RNA levels <50 copies/mL on 2 consecutive visits, loss of virologic response is the occurrence of the first value >50 copies/mL or loss to follow-up; participants who never achieved HIV RNA <50 copies/mL on 2 consecutive visits are also considered as having loss of virologic response.
Events are the numbers of participants with loss of virologic response versus the numbers of participants with no loss of virologic response (event free).
