简要总结
The purpose of this study is to see if it is safe and effective to give adefovir dipivoxil plus abacavir (ABC) plus efavirenz (EFV) plus amprenavir (APV) to HIV-infected patients who have failed to respond to previous treatment with protease inhibitors (PIs).
详细描述
Patients receive a treatment regimen of adefovir dipivoxil, abacavir, efavirenz, and amprenavir for 24 weeks. During the study, patients are evaluated for changes from baseline in plasma HIV-1 RNA levels and lymphocyte subsets and for development of adverse events and toxicities. Patients who experience virologic failure are discontinued from the study. After Week 24, patients with documented virologic response are eligible to continue receiving the study treatment and to attend scheduled follow-up visits.
