Key requirements
Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.
- 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.
- CD4 cell count >= 100 cells/mm3 within 14-21 days prior to the baseline visit.
- A minimum life expectancy of at least 1 year.

Who cannot join
- Co-existing Condition:
- Patients with any of the following symptoms and conditions are excluded:
- Active, serious infections (other than HIV infection) requiring parenteral antibiotic or antiviral therapy. Patients will be considered recovered from such infectious episodes if at least 2 weeks elapsed following the cessation of parenteral therapy before the baseline visit.
- Exhibiting evidence of a gastrointestinal malabsorption syndrome or chronic nausea or vomiting which may confer an inability to receive an orally administered medication.
- Malignancy other than cutaneous Kaposi's sarcoma (KS) or basal cell carcinoma. Patients with biopsy-confirmed cutaneous KS are eligible, but must not have received any systemic therapy for KS within 4 weeks prior to baseline and are not anticipated to require systemic therapy during the study.
- Any other clinical condition that in the opinion of the investigator would make the patient unsuitable for study or unable to comply with the dosing requirements.

About this study
Official title: A Phase II, Stratified, Randomized, Open-Label, Multi-Center Study of the Safety and Efficacy of Adefovir Dipivoxil and Indinavir in Combination With Zidovudine, Lamivudine, or Stavudine for the Treatment of Therapy Naive HIV-Infected Patients With CD4 Cell Counts >= 100 Cells/mm3 and HIV-1 RNA Copy Numbers >= 5,000 Copies/Ml
To evaluate the safety and tolerance of adefovir dipivoxil and indinavir administered orally in combination with zidovudine, lamivudine, or stavudine in HIV-infected patients with 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) by 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, open-label study of the safety and efficacy of adefovir dipivoxil with indinavir as quadruple therapy in combination with zidovudine and lamivudine, or as triple combination administered with either zidovudine or lamivudine or stavudine for 48 weeks in the treatment of HIV-infected patients with CD4 cell counts >= 100/mm3 and an HIV-1 RNA baseline copy number >= 5000 copies/ml. Patients will be randomized to adefovir dipivoxil, indinavir, zidovudine, and lamivudine or adefovir dipivoxil, indinavir, and a nucleoside inhibitor (randomly assigned to receive zidovudine, lamivudine, or stavudine) or to indinavir, zidovudine, and lamivudine. Additionally, a daily dose of L-carnitine will be administered to all patients randomized to an arm containing adefovir dipivoxil.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Indinavir sulfate, 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.
