About this study
Official title: A Prospective Randomized Double-Blind Trial of Three Maintenance Regimens for HIV-Infected Subjects Receiving Induction Therapy With Zidovudine, Lamivudine and Indinavir
To compare the proportion of patients who sustain suppression of plasma HIV RNA to undetectable levels [AS PER AMENDMENT 09/19/97: below 200 copies/mL by Roche UltraSensitive assay] among the 3 regimens during the maintenance phase.
The objective of antiretroviral therapy is to reduce HIV replication, preserve immunologic function and delay the development of HIV-related complications. In patients administered potent antiretroviral regimens, HIV RNA levels are reduced below 500 copies/ml of plasma and below the level of detection of commercially available assays. This protocol attempts to learn if a less intensive regimen can successfully sustain viral suppression after induction with a triple-drug regimen. The study also addresses whether HIV can be eradicated in patients following prolonged treatment with induction and maintenance regimens.
Read the detailed description
The objective of antiretroviral therapy is to reduce HIV replication, preserve immunologic function and delay the development of HIV-related complications. In patients administered potent antiretroviral regimens, HIV RNA levels are reduced below 500 copies/ml of plasma and below the level of detection of commercially available assays. This protocol attempts to learn if a less intensive regimen can successfully sustain viral suppression after induction with a triple-drug regimen. The study also addresses whether HIV can be eradicated in patients following prolonged treatment with induction and maintenance regimens.
All patients will receive open label induction therapy with zidovudine (ZDV), lamivudine (3TC) and indinavir (IDV) for 6 months. Following the 6 month induction phase, patients with undetectable plasma HIV RNA at weeks 16, 20 and 24 will enter the maintenance phase [blinded maintenance phase AS PER AMENDMENT 09/19/97] and be randomized to one of three maintenance regimens, i.e., either continued ZDV/3TC/IDV (control), or ZDV/3TC/IDV placebo or ZDV placebo/3TC placebo/IDV. Prior to randomization, patients are stratified according to entry HIV RNA level (greater than or equal to 30,000 or less than 30,000 copies/ml) and by prior ZDV therapy (at least 7 days or less than 7 days). After 12 months [AS PER AMENDMENT 09/19/97: 18 months] of maintenance therapy, treatment will be withdrawn at 6-month intervals in randomly-selected patients who have achieved undetectable HIV RNA. AS PER 09/19/97 AMENDMENT: After 18 months of blinded maintenance therapy, treatment is unblinded for patients whose HIV RNA levels remain detectable. Such patients receive optimal therapy, either continuing the protocol regimen or initiating alternative therapy.
AS PER AMENDMENT 2/27/98: An interim review conducted in January, 1998 demonstrated that the strategy of less intensive antiviral therapy after 6 months of IDV/3TC/ZDV induction therapy is less effective than continuation of triple drug therapy except for ZDV-naive patients assigned to ZDV/3TC. Therefore, the maintenance phase of this study has been discontinued.
Patients currently on blinded maintenance are unblinded immediately and have the option of reinitiating open-label triple therapy with IDV/3TC/ZDV or discontinuing study treatment. Patients currently on induction may register for continued open-label triple therapy or may discontinue study treatment. This amendment allows treatment extension so that subjects may receive open-label triple therapy until May 31, 1998. At that time, a rollover protocol or another modification with a longer period of drug supply may become available. Patients who choose to go off treatment are followed until May 31, 1998.
AS PER AMENDMENT 04/23/98: This study will now provide treatment with open-label ZDV/3TC/IDV until August 1, 1998. A rollover protocol or another 343 protocol modification with a longer period of drug supply may become available, but this cannot be guaranteed.
AS PER AMENDMENT 06/19/98: This study will now provide treatment with open-label ZDV/3TC/IDV until either November 1, 1998 or until 3 months after the rollover study (A5025) is available to the study sites (whichever comes first).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Indinavir sulfate, Lamivudine and Stavudine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 45 sites in United States.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 27 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 4 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 45 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00001084, which also lists 10 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Nov 2021; AzTrials last refreshed its copy on 7 Nov 2026.
