Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This is a study that will investigate the safety and efficacy of an investigational drug in Human immunodeficiency virus (HIV) infected patients.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Participants who completed 48 weeks of the original 48-week double-blind study were invited to continue in two extensions: MK0518-004-10 (NCT00100048), which extended the study to 144 weeks, and MK0518-004-20 (NCT00100048), which extended the study to 240 weeks. Participants who had been randomized to MK0518 in the base study continued at 400 mg MK0518 twice daily.

Participants randomized to efavirenz in the base study continued to receive efavirenz at the dosage given in the base study. The doses of open label tenofovir and lamivudine continued unchanged.
