About

Indinavir is usually taken three times a day. The purpose of this study is to see if it is safe and effective to take indinavir only twice a day plus nelfinavir (also taken twice a day) and efavirenz (taken once a day).

Full description

Patients receive a treatment regimen consisting of nelfinavir, indinavir, and efavirenz for 48 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. After Week 48, patients with documented virologic response are eligible to continue receiving study treatments and to attend scheduled follow-up visits. Patients who experience virologic failure are discontinued from the study.
