- Ages 16 years and older
- All sexes
- No healthy volunteers
- Child, Adult, Older adult
Who may be able to join
- Patients must have:
- Laboratory diagnosis of HIV infection (positive HIV antibody test confirmed by Western blot, p24 antigen assay, HIV-1 RNA, or HIV-1 culture).
- An HIV-1 RNA plasma titer >= 5000 copies/ml within 14-21 days prior to the baseline visit.

Who cannot join
- Co-existing Condition:
- Patients with any of the following symptoms and conditions are excluded:

- Exhibiting evidence of a gastrointestinal malabsorption syndrome or chronic nausea or vomiting that may confer an inability to receive an orally administered medication.

About this study
Official title: A Phase II, Stratified, Randomized, Double-Blind, Multi-Center Study of the Safety and Efficacy of Adefovir Dipivoxil (ADF) at Two Dose Levels in Triple Combination Therapies With Protease Inhibitors (PI) and Nucleoside Reverse Transcriptase Inhibitors (RTI) for the Treatment of HIV-Infected Patients With CD4 Cell Counts >= 100/mm3 and HIV-1 RNA Copy Numbers >= 5,000 Copies/Ml and Prior RTI Therapy But No Prior PI Therapy
To evaluate the safety and tolerance of the combination of adefovir dipivoxil at two comparative doses and nelfinavir plus saquinavir SGC administered orally (Group 1) vs. the combination of adefovir dipivoxil and nelfinavir plus either zidovudine, lamivudine, or stavudine (Group 2) vs. the combination of adefovir dipivoxil and saquinavir SGC plus either zidovudine, lamivudine, or stavudine (Group 3) in HIV-infected patients with prior nucleoside reverse transcriptase inhibitor therapy but no prior exposure to protease inhibitors who have CD4 cell counts >= 100 cells/mm3 and an HIV-1 RNA baseline copy number >= 5000 copies/ml. To determine the proportion of patients whose plasma HIV-1 RNA level falls below the level of detection (<500 copies/ml) at 20 weeks of study therapy and the average reduction in HIV-1 RNA from baseline through study week 20. To evaluate the durability of the antiviral response through 48 weeks of study in patients who continue on study therapy after week 24.
Read the detailed description
This protocol is a stratified, randomized, double-blind, dose-comparative study of the safety and efficacy of adefovir dipivoxil in combination with nelfinavir and saquinavir soft gel capsules (SGC) or adefovir dipivoxil in combination with nelfinavir or saquinavir SGC plus a nucleoside analog (zidovudine, lamivudine, or stavudine).
Patients will be randomized to adefovir dipivoxil with nelfinavir and saquinavir or adefovir dipivoxil with nelfinavir or saquinavir plus a nucleoside analog (zidovudine, lamivudine, or stavudine). Within each treatment arm, patients will be randomized to 1 of 2 doses of adefovir dipivoxil in a blinded manner. Patients randomized to receive a nucleoside analog will then be assigned to receive either zidovudine, lamivudine, or stavudine based upon their previous RTI therapy. A daily dose of L-carnitine will be administered to all patients.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Nelfinavir mesylate, Levocarnitine and Adefovir dipivoxil in people with HIV Infections, run by Gilead Sciences at 15 sites in 2 countries.
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 6 inclusion and 21 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 24 Jun 2005. 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, Puerto Rico. 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?
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 24 Jun 2005.
