A Study of Saquinavir Soft Gelatin Capsules Combined With Other Anti-HIV Drugs in HIV-1 Infected Patients

Eligible patients will be stratified by HIV-1 RNA level into 2 populations: 1) \>= 5,000-30,000 HIV-1 RNA, 2) \> 30,000 HIV-1 RNA. All patients will be randomized to 1 of 3 treatment arms: Arm A - Saquinavir soft gel capsules (SQV SGC) + 2 new nucleoside analogs (reverse transcriptase inhibitors \[RTIs\]), Arm B - SQV SGC + nelfinavir + stavudine (d4T) or a new RTI, or Arm C - SQV SGC + ritonavir + d4T or a new RTI. All patients will undergo plasma HIV-1 RNA determinations, CD4 lymphocyte counts, hematology and chemistry blood work at baseline, weeks 4, 8, 12, 16 and 24.
