About this study
To compare effects on CD4 counts and serum viral RNA among HIV-seropositive, zidovudine (AZT)-experienced patients in three treatment arms: indinavir sulfate ( MK-639; Crixivan ) plus AZT plus lamivudine ( 3TC ) versus MK-639 alone versus AZT/3TC.
Read the detailed description
AZT-experienced patients are randomized to receive MK-639/AZT/3TC or MK-639 alone or AZT/3TC. Additionally, patients who have received < 6 months of AZT or who are intolerant but received prior 3TC or who require concomitant rifampin therapy may receive open-label MK-639.
