About this study

Official title: A Randomized, Double-Blind, Phase II Study of 141W94 (VX-478) Monotherapy vs. 141W94 (VX-478) Plus ZDV Plus 3TC in HIV Infected Individuals

To determine the proportion of patients whose plasma HIV-1 RNA level remains below a detectable level (less than 500/ml) after 24 weeks of study therapy with either 141W94 monotherapy or 141W94 plus zidovudine (ZDV) and lamivudine (3TC). To determine the safety and tolerability of 141W94 monotherapy and the combination of 141W94 plus 3TC in patients with HIV infection.

Although dramatic inhibition of HIV-1 replication is achieved with ritonavir or indinavir monotherapy, in both cases maximum suppression required combination treatment together with nucleoside analog RT inhibitors. This study tests the hypothesis that monotherapy with 141W94 doses that result in Cmin levels far in excess of the IC90 corrected for plasma protein binding for HIV-1 can achieve the same virologic and immunologic effects in terms of magnitude and durability, as has been observed with combinations of other protease inhibitors plus nucleoside analogs.

Although dramatic inhibition of HIV-1 replication is achieved with ritonavir or indinavir monotherapy, in both cases maximum suppression required combination treatment together with nucleoside analog RT inhibitors. This study tests the hypothesis that monotherapy with 141W94 doses that result in Cmin levels far in excess of the IC90 corrected for plasma protein binding for HIV-1 can achieve the same virologic and immunologic effects in terms of magnitude and durability, as has been observed with combinations of other protease inhibitors plus nucleoside analogs.

In this randomized, double-blind study, patients' HIV RNA is screened 30 days prior to entry. Patients satisfying enrollment criteria must have been on a stable antiretroviral regimen for 30 days prior to study screening and remain on the same regimen until entry. Patients are stratified based on the screening HIV-1 RNA copy number obtained within 30 days of entry: 5,000 - 50,000 copies/ml versus greater than 50,000 copies/ml. In addition, patients are stratified based on previous antiretroviral use: naive versus experienced. Patients are randomized to one of 2 treatment arms: Arm A - 141W94, plus Zidovudine (ZDV) and Lamivudine (3TC) or Arm B - 141W94, plus ZDV placebo and 3TC placebo.

[AS PER AMENDMENT 8/25/97: Patients assigned to the monotherapy arm are advised to discontinue their study medication immediately and initiate antiretroviral therapy with indinavir, nevirapine, stavudine and 3TC, as outlined in ACTG 347 roll-over protocol, ACTG 373. Patients in the three-drug arm continue on study therapy.] [AS PER AMENDMENT 12/19/97: Patients receive study treatment for 56 weeks and are followed through week 68.]

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Amprenavir, Lamivudine and Zidovudine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 15 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 20 inclusion and 22 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 15 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 NCT00001085, which also lists 4 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.
