A Multicenter, Open-Label, Randomized, 24-Week Study to Compare the Safety and Activity of Indinavir Sulfate, 800 Mg q 8 h Versus 1,200 Mg q 12 h in Combination With Zidovudine and 3TC

Condition(s) targeted: HIV Infections
Intervention: Indinavir sulfate (Drug); Lamivudine (Drug); Stavudine (Drug); Zidovudine (Drug)
Phase: Phase 3
Sponsored by: Merck
To demonstrate that the antiviral activity and safety/tolerability of a test regimen of
indinavir is equivalent to that of a control regimen of indinavir when each is coadministered
with zidovudine (ZDV) (or stavudine, d4T) and lamivudine (3TC) for 24 weeks to protease
inhibitor- and 3TC-naive HIV-1-seropositive patients. To characterize the steady-state
pharmacokinetic profiles of indinavir, ZDV (or d4T), and 3TC in the presence of each other,
for both the control and test regimen groups.
Official title: A Multicenter, Open-Label, Randomized, 24-Week Study to Compare the Safety and Activity of Indinavir Sulfate, 800 Mg q 8 h Versus 1,200 Mg q 12 h in Combination With Zidovudine and 3TC
Study design: Treatment, Pharmacokinetics Study
Patients are randomized to 1 of 2 arms:
Arm A: Indinavir plus ZDV plus 3TC. Arm B: Indinavir (test dose) plus ZDV plus 3TC. NOTE: d4T
may be substituted for zidovudine for toxicity management. Patients are stratified based on
prior use of nucleoside analogs (naive vs experienced to ZDV, dideoxyinosine [ddI],
dideoxycytidine [ddC], and d4T) and screening viral RNA results (lower than 50,000 copies/mL
vs more than 50,000 copies/mL).
Minimum age: 16 Years.
Maximum age: N/A.
Patients must have:
- HIV-1 seropositive status.
- CD4 count greater than 100 cells/mm3.
- Viral RNA above 10,000 copies/mL.
- Consent from parent or guardian if less than 18 years of age.
- Prior therapy with protease inhibitors.
- Prior therapy with 3TC.
