Study information

Primary study designInterventional
Study designRandomised controlled trial
Secondary study designRandomised controlled trial
Scientific title
Study objectivesTo assess the virological and immunological response in naive patients undergoing induction (24 weeks of intensive therapy with three nucleoside reverse transcriptase inhibitors [NRTIs] plus either a protease inhibitor or a non-nucleoside) followed by 48 weeks of maintenance therapy with three NRTIs.
Ethics approval(s)Not provided at time of registration
Health condition(s) or problem(s) studiedHuman immunodeficiency virus (HIV) infection
InterventionPatients are randomly assigned to receive either:

1. Retrovir (AZT) + Lamivudine (3TC) + Trizivir (ABC) + Efavirenz (Sustiva), or
2. AZT + 3TC + ABC + Lopinavir/Ritonavir (Kaletra)

After 24 weeks, patients in both arms showing undetectable viral load will receive Trizivir for 48 more weeks.
Intervention typeDrug
PhaseNot Specified
Drug / device / biological / vaccine name(s)Trizivir (ABC), Lamivudine (3TC), Retrovir (AZT), Efavirenz (Sustiva), Lopinavir/ritonavir (Kaletra)
Primary outcome measure(s)

Proportion of patients with viral load below 20 copies/ml (polymerase chain reaction [PCR] estandar, Amplicor Monitor Roche Ultrasensible) at 72 weeks.

Key secondary outcome measure(s)

1. Proportion of patients with CD4+ cell count above 200 c/ml at 72 weeks
2. Proportion of patients with viral load <20 copies/ml at 24 weeks
3. Time to treatment failure
4. Duration of response
5. Incidence of adverse events (clinical and laboratory) leading to discontinuation of the study drugs
6. Incidence of C events (CDC 1993)
7. Death for any cause
