AS PER AMENDMENT 5/7/97: Based on an interim analysis performed after 72 patients had completed 8 weeks of therapy, the study was closed as of March 7, 1997. Patients currently enrolled may stop their participation in the trial and seek other anti-retroviral therapies or may continue on study. Patients on hard capsule saquinavir who remain on study will be switched to indinavir at 8 weeks. Patients on soft gel capsule saquinavir may switch immediately to indinavir or, when results of HIV RNA and CD4 cell counts are available, may choose to switch to indinavir or remain on soft gel capsule saquinavir. Patients receiving indinavir will continue that agent. Follow-up for all patients will end on 7/4/97.
