Pharmacodynamics of Intermittent IL-2 Infusions in HIV Seropositive Patients
NCT00001474 · View on ClinicalTrials.gov ↗
Study Summary
This study is designed as a randomized, open trial of intermittent continuous infusions of Interleukin-2 in HIV seropositive patients with a CD4 cell count between 200 and 500 cells/mm(3). The goal of the study is to determine the optimal duration of each infusion, and the optimal interval between infusions. Thirty-six patients will be randomized to 3 groups: Group A will be the control group with a regimen of five day infusions of IL-2 every eight weeks; Group B will receive IL-2 infusions every eight weeks, however the duration of each infusion will be determined by parameters reflecting T cell proliferation, with discontinuation of each infusion at a point when the response appears to be maximized; Group C will receive five day infusions of IL-2; however the interval between infusions will be determined by the response seen to the prior infusion, with the goal of administering infusions while the CD4 cell count remains above baseline from the prior infusion. The dose of interleukin-2 to be used will be 9 MIU by continuous infusion daily. All patients will be evaluated at the NIH at least every 4 weeks, and at that time safety labs and immune studies will be performed. In addition, patients in Groups B and C will undergo a laboratory evaluation weekly, at which time immune parameters, including CD4 number and percent, spontaneous blast transformation, soluble IL-2 receptor levels, and viral parameters, including branched DNA assay and p24 antigen, will be determined. The study duration will be approximately one year.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT00001474
The ClinicalTrials.gov registry entry for NCT00001474 describes a study currently listed as completed. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 36 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is National Institute of Allergy and Infectious Diseases (NIAID), which has 1,295 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 1 condition, with HIV Infection appearing as the primary indexed condition, and to 1 intervention — of which Interleukin-2 is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT00001474 reports 1 study location spanning 1 distinct geographic area — top geographies include Maryland. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
