About this study
To determine the safety profile of recombinant human CD4-immunoglobulin G (CD4-IgG) and zidovudine (AZT) combination therapy in patients with AIDS or AIDS-related complex (ARC); to assess pharmacokinetic (blood level) properties of CD4-IgG in combination with AZT; and to obtain preliminary indication of the antiviral and immunologic effects of CD4-IgG in combination with AZT in patients with AIDS and ARC.
Treatment of AIDS has been directed toward the underlying retroviral infection as well as toward specific opportunistic infections and malignancies that are associated with the syndrome. The most extensively studied drugs are reverse transcriptase inhibitors such as AZT and other nucleoside analogs, including didanosine (ddI) and dideoxycytidine (ddC). The most extensive clinical experience has been achieved with AZT. These clinical trials indicated a decreased incidence of opportunistic infection and increased survival in patients with AIDS. However, AZT treatment is associated with dose-limiting toxicities. Additionally, identification of resistance to AZT has increased the need to test the effectiveness of AZT in combination with other drugs. CD4-IgG is capable of binding to HIV envelope protein (gp120) and inhibiting HIV infectivity in test tube studies. Potential therapeutic benefit in patients with HIV infection may be derived from CD4-IgG.

AMENDED: Previously, rCD4-IgG had been administered on a mcg/kg basis. Subjects now receive rCD4-IgG as a fixed dose. Changes to the maintenance schedule were made to accommodate the new dosages. Original design: This study is divided into two parts: A pharmacokinetic evaluation, and a safety evaluation. The pharmacokinetic evaluation is done in selected patients. For the safety evaluation patients will receive rCD4-IgG at a fixed dose level twice weekly by intravenous bolus injection (over 1 minute) for 12 weeks. Zidovudine (AZT) is administered orally 3 times daily at one of two dose levels. Eight subjects, at least 4 of whom with p24 levels greater than 75 pg/m, are entered at each dose level of CD4-IgG beginning with dose level 1. If 3 or more patients at a dose level experience grade 3 or 4 toxicity then no further patients will be added to that or higher dose levels. Pharmacokinetics of CD4-IgG alone and in combination with AZT is evaluated in patients at dose level 2 only. Patients receive one IV bolus of CD4-IgG on day 1 and samples are drawn beginning 15-30 minutes prior to the CD4-IgG injection. There is an 8 day washout period. Beginning on day 9 and continuing through day 24, patients receive AZT daily. CD4-IgG is administered by IV bolus on day 16. Samples are drawn beginning 15-30 minutes prior to the injection of CD4-IgG. The pharmacokinetic evaluation terminates 8 days after the second CD4-IgG injection (day 24). Extended treatment will be made available to patients at the discretion of the Principal Investigator.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing CD4-IgG and Zidovudine 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 7 inclusion and 28 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 6 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 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 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 NCT00000976, 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 6 Aug 2008.
