Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 12 months to 8 years
  • All sexes
  • No healthy volunteers
  • Child

Who may be able to join

  • Children may be eligible for this study if they:
  • Are HIV-positive with no symptoms or moderate symptoms.
  • Are between 1 and 8 years old (consent of parent or guardian required).
  • Have had a CD4 cell count greater than 200 for the past 3 months. If a child had a lower CD4 count before this time, then he/she must have been on stable anti-HIV therapy for the past 3 months.

About this study

Official title: Phase I/II Study of the Safety and Immunogenicity of Live-Attenuated Varicella Vaccine (Varivax) in HIV-Infected Children

The purpose of this study is to see if it is safe to give Varivax to HIV-positive children and whether it protects children from infection. Varivax is a vaccine against varicella zoster virus (VZV), the virus that causes chickenpox (varicella) and shingles (zoster).

VZV can cause many serious complications in HIV-infected children. Varivax is a VZV vaccine that has been approved for use in healthy children. More research is needed to find out how this vaccine will affect HIV-infected children.

Read the detailed description

Primary varicella infection, or chickenpox, can be devastating to HIV-infected children because complications occur at higher rates in immunocompromised hosts. Current passive prophylaxis measures with varicella-zoster immune globulin are suboptimal because administration must be repeated for each exposure during the child's lifetime and timely notification of exposure is not always possible. Since Varivax has been licensed for routine vaccination of healthy individuals, it must be determined whether this vaccine can be safely administered to HIV-infected children.

Thirty-six children who are varicella zoster virus (VZV)-naive (treatment group) receive Varivax at Weeks 0 and 12, with a possible boost at Week 52 if the patient is still seronegative for VZV and cytomegalovirus infection. Twenty children who have a history of wild-type varicella exposure within the past year (control group) receive no study treatment. All patients are either asymptomatic or mildly symptomatic for HIV infection. Patients make 12-14 visits to the clinic. [AS PER AMENDMENT 9/9/99: This study has been reorganized into two cohorts (asymptomatic and symptomatic). In the asymptomatic cohort, accrual has been completed with 40 patients in Treatment Group I and 19 in the control group. This phase of the study demonstrated that Varivax was well tolerated in 48 HIV-infected children with asymptomatic disease. The symptomatic cohort includes Treatment Groups II and III, each with 30 patients. The first 10 patients from Group II are monitored for 42 days following the first dose of vaccine before the remaining 20 are accrued. Once the first 10 patients in Group II have been evaluated with acceptable toxicity and immunologic profiles, the remaining 20 Group II and the first 10 Group III patients are enrolled. The first 10 Group III patients are also followed for acceptable toxicity and immunologic response before accrual of the remaining 20 Group III patients.]

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Varicella Virus Vaccine (Live) in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 25 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 4 inclusion and 8 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 29 Oct 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 25 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 NCT00000837, 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 29 Oct 2021.
