Brief Summary

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

To evaluate the anti-HIV activity, safety, and tolerance of adefovir dipivoxil ( bis-POM PMEA ) in combination with standard antiretroviral therapy for 48 weeks.

Detailed Description

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

Patients are randomized to receive either adefovir dipivoxil or placebo daily for 24 weeks, after which all patients will receive open-label drug for an additional 24 weeks. Study drug is administered in combination with a current antiretroviral regimen for the entire 48 weeks. Patients are followed every 4 weeks during the first 24 weeks of study, then every 8 weeks during the last 24 weeks.
