A Study to Evaluate the Safety and Efficacy of Raltegravir (MK0518) in HIV-Infected Patients Failing Current Antiretroviral Therapies (MK0518-018 EXT2)
4 september 2015 uppdaterad av: Merck Sharp & Dohme LLC
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
This study will investigate the safety and efficacy of raltegravir as a therapy for HIV-infected patients failing current therapy with 3-class antiviral resistance.

Detaljerad beskrivning
The primary double-blind study of raltegravir versus placebo was extended to 156 weeks and was followed by an open-label raltegravir phase in which continuing participants from both the raltegravir and placebo groups received open-label raltegravir for an additional 84 weeks for a maximum duration of up to 240 weeks.
Participants who had viral failure after Week 16 may have received open-label raltegravir until Week 240.

Double-Blind Extension - Week 156: Percentage of Participants Without Loss of Virologic Response
Tidsram: 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).
