About this study

To evaluate the relationship between viral suppression and changes in immune function, as measured by the restoration of delayed-type hypersensitivity (DTH) and lymphoproliferative (LP) responses, observed after 48 weeks of treatment with highly active antiretroviral therapy (HAART) in ACTG 315. To evaluate the durability of the antiviral and immunologic effects of long-term treatment with HAART.

Given the extensive immunologic and virologic data available from ACTG 315, follow-up studies of this advanced-disease population are indicated to primarily ascertain the impact of long-term suppression of viral replication on immunologic reconstitution or re-education and the durability of the antiviral effects of HAART.

Read the detailed description

Given the extensive immunologic and virologic data available from ACTG 315, follow-up studies of this advanced-disease population are indicated to primarily ascertain the impact of long-term suppression of viral replication on immunologic reconstitution or re-education and the durability of the antiviral effects of HAART.

Patients continue their current ACTG 315 regimen of zidovudine plus lamivudine plus ritonavir in an open-label fashion while undergoing 6 weeks of extensive evaluations. Treatment decisions are based on baseline viral load (mean of 2 viral load measurements taken during 6-week evaluations). Patients with HIV-1 RNA less than 100 copies/ml continue the ACTG 315 regimen. Patients with HIV-1 RNA 100-3000 copies/ml may continue the ACTG 315 regimen or initiate a new HAART regimen selected by the local investigator or primary care physician. Patients with HIV-1 RNA greater than 3000 copies/ml initiate a new HAART regimen selected by the local investigator or primary care physician. [AS PER AMENDMENT 4/10/00: Changes to regimens must be done in consultation with the study team. The team acknowledges that a viable regimen may not be available for a given patient when the plasma HIV RNA level is above 3,000 copies/ml. In this case, patients may remain on their failing regimen with evaluation every 8 weeks until a viable regimen becomes available to them.] All patients are required to maintain a HAART regimen that contains at least 3 drugs, 1 of which is a protease inhibitor. [AS PER AMENDMENT 3/5/01: All patients are required to maintain a HAART regimen that is approved by the protocol chairs.] Zidovudine (ZDV), lamivudine (3TC), stavudine (d4T), didanosine (ddI), delavirdine (DLV), ritonavir (RTV), and saquinavir soft gel capsules (SQV sgc) are provided on-study. [AS PER AMENDMENT 9/19/00: ZDV, 3TC, 3TC/ZDV combination tablet, d4T, ddI, DLV, RTV, and SQV sgc will be supplied by the protocol for 182 weeks.] [AS PER AMENDMENT 3/5/01: The following antiretroviral medications will be supplied by the protocol for Steps 1 and 2: ZDV, 3TC, 3TC/ZDV combination tablet, d4T, ddI, DLV, RTV, and SQV sgc.] Therapy is continued for 54 weeks. [AS PER AMENDMENT 10/6/98: The initial 54-week trial is followed by an additional 2 years of long-term evaluation. Also per this amendment, protocol therapy is initiated at Week 6.] [AS PER AMENDMENT 9/19/00: The initial 54-week trial is followed by an additional 2.5 years of long-term evaluation.] [AS PER AMENDMENT 3/5/01: Step 1 has an initial 54 weeks of treatment followed by 140 weeks of long-term follow-up. Step 2 has an additional 36 weeks of long-term follow-up. Patients who complete the final visit on Step 2 (Week 230) should return to the clinic 4 weeks after receiving the last dose of study-provided medication to complete the final evaluations.] [AS PER AMENDMENT 10/6/98: Patients may co-enroll in an immunology substudy.] [AS PER AMENDMENT 6/11/99: The immunology substudy is being piloted in 3 to 4 volunteers and may not proceed until the feasibility of the pilot project is reviewed.]

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ritonavir, Saquinavir and Delavirdine mesylate in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 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 12 inclusion and 26 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 3 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 NCT00000891, which also lists 6 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.
