About this study

Official title: Killer Cells and Viral Load in Vertical HIV Infection

This observational study will evaluate data from infants born to HIV infected mothers in order to better characterize disease progression in early HIV infection.

Read the detailed description

The role of HIV-specific cytotoxic T-lymphocytes (CTL) in controlling viremia and protecting against disease progression following vertical infection may be dependent upon CTL functional responses as well as on the timing of detection, magnitude, and breadth of the responses. Novel and sensitive assay systems (MHC-peptide tetramers, ELISPOT assays, intracellular cytokine assays) have enhanced the detection and characterization of virus-specific CTL responses in the peripheral blood. This study will use these novel methods to examine the timing of detection, magnitude, specificity, and in vitro functional properties of HIV-specific CTL in infants; to evaluate the effects of potent combination antiretroviral therapy on HIV-specific CTL in infants; and to evaluate the immunogenicity of recombinant pox-based vaccines in HIV infected infants with prolonged viral suppression following early potent combination antiretroviral therapy.

Blood samples from infants born to HIV infected women will be obtained from infants enrolled in other HIV trials. Generally, samples will be obtained at birth, Week 1, and Months 1, 2, 4, 6, 9, and 12.

Questions about this trial

What is this clinical trial studying?

An observational study of 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 1 inclusion and 0 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 26 Sep 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.

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 NCT00073229, 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 26 Sep 2008.
