About this study

To determine the safety of polyethylene glycolated IL-2 (PEG IL2) administered weekly or biweekly (per amendment) in a setting of oral zidovudine (AZT). To determine the effect of PEG IL2 in combination with AZT on parameters assessing the immune system as well as HIV virus and antibody titers. To evaluate a chronic dosing study phase offered to patients who complete the initial 25-week regimen.

Recent research has focused on enhancing cell-mediated immunity and reducing or eliminating viral replication (reproduction and growth). A main thrust of current treatment is the combination of antiviral drugs that may be more effective when combined than when each is used alone.

Recent research has focused on enhancing cell-mediated immunity and reducing or eliminating viral replication (reproduction and growth). A main thrust of current treatment is the combination of antiviral drugs that may be more effective when combined than when each is used alone.

Four groups are studied for a period of at least 25 weeks. Patients are observed for a minimum of 6 hours after infusion of PEG IL2. The 4 groups of patients are: Group A - asymptomatic with T4 count > 400 cells/mm3 (7 patients); Group B - asymptomatic with T4 count between 200 and 400 cells/mm3 (7 patients); Group C - asymptomatic with T4 count < 200 cells/mm3 (5 patients); Group D - diagnosed as having AIDS related complex (ARC) or AIDS (7 patients). All patients receive AZT. After a minimum 2-week period of AZT, patients receive an infusion of PEG IL-2 at 3 consecutive weekly intervals, followed by a 3-week period of AZT alone. This cycle (3 weeks of AZT and PEG IL-2 followed by 3 weeks of AZT alone) is repeated a total of three times (for a total of 18 weeks) followed by 8 weeks of AZT alone.

PER AMENDMENT: Ten patients may qualify for one of two groups: Group 1 - T4 count 200 - 400 cells/mm3 and meet all criteria established for Group B of the original protocol; Group 2 - T4 count < 200 cells/mm3 and meet all criteria established for Groups C and D of original protocol. Patients will receive an amended schedule of PEG IL2 IV every other week for eight doses, with dose escalation every other week for eight weeks permitted only in Group 2 patients who failed to show a 20 percent rise in T4 count at week 9 and who suffered no CNS or other adverse events at the lower dose.

PER ADDITIONAL AMENDMENT: Up to 10 additional patients may be treated at each dose of PEG IL2 on the biweekly schedule. Patients who respond to treatment on the biweekly schedule are eligible for an additional 9 weeks at their current dose.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Interleukin-2, Polyethylene Glycolated and Zidovudine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site 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 8 inclusion and 34 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 Aug 2008. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 NCT00000664, which also lists 1 linked publication.

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 Aug 2008.
