About this study

Official title: A Multi-Site Evaluation of Virologic, Immunologic, and Clinical Natural History of Participants Enrolled in Phase I and Phase II HIV-1 Vaccine Protocols or HIV-1 Vaccine Preparedness Cohorts Who Develop HIV-1 Infection Subsequent to Trial Enrollment

Despite risk reduction counseling, some individuals in HIV vaccine trials or vaccine preparedness studies may engage in risk behavior that results in HIV infection. The purpose of the HVTN 403 study is to find out more about how persons respond to HIV infection if they have received an experimental HIV-1 vaccine before they became HIV infected.

Some people in HVTN 403 received an experimental HIV vaccine as a participant in a clinical trial before getting infected with HIV. Other people in this study were in a vaccine preparedness study when they got infected with HIV. None of these individuals became infected with HIV as result of their participation in an HIV vaccine or vaccine preparedness study. HVTN 403 will compare immune responses between those who previously received an experimental HIV vaccine and those who did not. Information learned from this study may be important in guiding future developments of new HIV vaccines and other treatments for HIV and AIDS.

Read the detailed description

It is important to study persons vaccinated with candidate HIV-1 vaccines who have become HIV-1 infected for the following reasons. First, if transient HIV-1 infection is detected and then is effectively suppressed or cleared, it will be important to document the antigenic relationship between the breakthrough virus and the vaccine epitopes to attempt to answer questions about the specificity and breadth of the immune response and the determinants of immunity. A second reason is to gain a better understanding of vaccine-induced responses in those participants who are transiently or persistently HIV-1-infected compared to placebo recipients who become HIV-1-infected. If the vaccine does not prevent HIV-1 infection, it will be important to characterize the course of the disease as measured by longitudinal viral load measurements, CD4+ counts, and clinical symptoms. Understanding the breadth, magnitude, and specificity of the immune response in partially or fully immunized vaccinees after infection and the impact on clinical symptoms and disease progression can potentially result in valuable information for the subsequent design of vaccine efficacy trials and, ultimately, in consideration of potential effectiveness of HIV-1 vaccines.

Study visits occur at Days 0, 7, 14, 28, then at 2 months, 3 months, 6 months, and every 6 months thereafter. At these visits, patients are given a physical exam, blood is drawn, and a donation of genital fluids is requested at certain visits. Patients are asked to donate samples of either semen (men) or cervical secretions (women); viral load is measured and compared to the amount and types of virus in the blood. He/she may refuse to donate these genital fluids and still be eligible to remain in the study. Primary medical care or medications for HIV infection are not provided by this study.

Questions about this trial

What is this clinical trial studying?

An observational study of HIV Infections, run by HIV Vaccine Trials Network at 21 sites in 4 countries.

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 2 inclusion and 1 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 2 Sep 2010. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 21 sites in United States, South Africa, Peru, Brazil. 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 NCT00029913, 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 2 Sep 2010.
