Safety/Immunogenicity of Immunizations of ALVAC-DC-SC vs ALVAC-SC
A Phase 1 study testing ALVAC(2)120(B,MN)GNP (vCP1452) and Keyhole-Limpet Hemocyanin in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 sites in United States.
Trial summary
The purpose of this study is to determine how safe it is to give patients a shot that has a mixture of a vaccine and dendritic cells (DCs), a special kind of immune cell, and how safe it is to give a shot of the vaccine alone. Current HIV vaccines have not been strong enough to give good immune responses. Read more about this study

About this study
Official title: A Phase I/II Study to Evaluate the Safety and Immunogenicity of the Subcutaneous Administration of ALVAC-HIV vCP1452 Infected Autologous Dendritic Cells Versus the Subcutaneous Administration of ALVAC-HIV vCP1452 To HIV-Infected Subjects
The purpose of this study is to determine how safe it is to give patients a shot that has a mixture of a vaccine and dendritic cells (DCs), a special kind of immune cell, and how safe it is to give a shot of the vaccine alone.
Current HIV vaccines have not been strong enough to give good immune responses. Research has shown that the immune response to a vaccine delivered by DCs is greater than the response without DC delivery. A5130 is a study that seeks to give good delivery of the vaccine to important immune cells of the body.
Read the detailed description
Cytotoxic T-cell lymphocyte (CTL) responses are important in viral destruction and thereby in the protective immune response to viral infection. Current HIV vaccines do not consistently elicit strong CTL responses. The limited immune response of current HIV vaccines could be attributed, in addition to other causes, to failure of the vaccine to reach the appropriate cells to initiate a robust immune response. DCs particularly are effective in stimulating primary T-cell-dependent immunity. Antigen-bearing DCs are used as adjuvants for active immunotherapy in humans, particularly to increase host resistance to tumors and certain viral infections. A5130 is an exploratory, proof-of-concept study that seeks to ensure adequate delivery of the vaccine to important antigen-presenting cells.
Patients are randomized into 1 of 2 vaccination groups at entry. Group A: Patients receive an SC vaccination with DCs infected with ALVAC-HIV vCP1452. DC exposure to KLH occurs at Weeks 3 and 7. Leukopheresis occurs at entry.
Group B: Patients receive an SC vaccination with ALVAC-HIV vCP1452 without DCs. KLH injections are administered at Weeks 3 and 7.
Patients in both groups receive their vaccinations at Weeks 3, 7, and 15. This study consists of 4 steps but not all patients necessarily qualify to enter Step II, Step III, or Step IV.
Step I: vaccination phase. Step II: withdrawal of potent ART. Step III: optional discontinuation of ART. Step IV: reinitiation of ART. [AS PER AMENDMENT 04/10/02: Step V: follow-up period off potent ART.]

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The purpose of this study is to determine how safe it is to give patients a shot that has a mixture of a vaccine and dendritic cells (DCs), a special kind of immune cell, and how safe it is to give a shot of the vaccine alone.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing ALVAC(2)120(B,MN)GNP (vCP1452) and Keyhole-Limpet Hemocyanin in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 9 inclusion and 15 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 1 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 2 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 NCT00026624, 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 1 Nov 2021.
