About this study

Official title: A Phase I Clinical Trial to Evaluate the Safety and Immunogenicity of a Booster Dose of a Recombinant Multiclade HIV-1 Adenoviral Vector Vaccine, VRC-HIVADV014-00-VP, in Uninfected Subjects Who Were Previously Immunized With VRC-HIVDNA009-00-VP in VRC 004

This study will test the safety and side effects of an experimental vaccine booster against HIV. A vaccine is a substance given to try to create immunity or resistance to a disease or infection. The vaccine used in this study is called VRC-HIVADV014-00-VP. It is made from an adenovirus (a common virus that causes upper respiratory infections) that contains DNA (genetic material) of three HIV proteins. Injected into a human, the viral DNA instructs the body to make small amounts of some HIV proteins. VRC-HIVADV014-00-VP will be given to people who previously received a vaccine called VRC-HIVDNA009-00-VP under NIH protocol 03-I-0022. Important: Study participants cannot catch an adenovirus infection or HIV or AIDS from the vaccine or any proteins made from it.

Healthy normal volunteers who participated in NIH protocol 03-I-0022 may be eligible for this study. They must have completed three injections of 4 mg or 8 mg of VRC-HIVDNA009-00-VP without experiencing a serious side effect that was possibly related to the vaccine. Candidates are screened with a medical history, clinical evaluation, blood and urine tests, and HIV and pregnancy counseling.

Participants receive one injection of VRC-HIVADV014-00-VP the day they enroll in the study (study day 0). They are observed for at least 30 minutes after immunization. At home, they record their temperature and any symptoms they may experience, including any effects at the injection site, for 5 days and call a study nurse 1 or 2 days after the injection. They immediately report any symptoms to the clinic staff and, if necessary, come to the clinic for an examination.

Participants have five additional clinic visits during the study, at weeks 2, 4, 6, 12 and 24, each lasting about 2 hours. At each visit, they are checked for health changes or problems and are asked about medications they are taking. Blood is drawn for immune function testing, HLA typing (a genetic test of immune system markers), and other genetic factors. A urine sample is collected at some visits. Additional laboratory tests may be requested between visits. Some participants may undergo apheresis at the week 4 visit to collect a large number of white blood cells for laboratory tests to see how the immune system responds to the study vaccine. For this procedure, blood is collected through a needle in an arm vein and flows through a catheter (plastic tube) into a machine that separates it into its components by centrifugation (spinning). The white cells are extracted and the rest of the blood is returned through another needle in the other arm. The procedure takes about 1 to 3 hours.

Participants are tested three or more times for HIV and are questioned about their sexual behavior and drug use. They complete a "social impact" questionnaire at week 24 that includes questions about any problems they may have experienced from their participation in the study regarding such things as insurance, health care, friends, family, employment, housing, education, or government agencies.

Read the detailed description

Study Design: This is a Phase I open-label study to examine safety, tolerability and immune response of a multiclade HIV adenoviral vector vaccine as a booster vaccination in uninfected adults. The hypothesis is that this vaccine will be safe as a booster vaccine and elicit immune responses to HIV. The primary objective is to evaluate the safety and tolerability of a VRC-HIVADV014-00-VP booster vaccination in uninfected subjects who previously received 3 injections of VRC-HIVDNA009-00-VP more than one year prior to the study vaccination. The secondary objectives include immunogenicity evaluations and adenovirus serotype 5 (Ad5) antibody titers, and social impacts. Exploratory evaluations include epitope mapping and other immunogenicity evaluations.

Product Description: VRC-HIVADV014-00-VP is a recombinant product composed of 4 adenoviral vectors (Ad) (in a 3:1:1:1 ratio) that encode the HIV-1 Gag/Pol polyprotein from clade B and HIV-1 Env glycoproteins from clades A, B, and C, respectively.

Subjects: Healthy adult volunteers who previously received three injections of VRC-HIVDNA009-00-VP at a dosage of 4 mg or 8 mg in the VRC 004 study (03-I-0022): subjects in these groups were between 20 and 39 years old at time of enrollment in VRC 004; those who participate in VRC 009 will be approximately 1-3 years older at the time of enrollment into VRC 009.

Study Plan: Up to thirty-two volunteers will receive one 1 mL injection of the study agent at a dosage of 1 x 10(10) PU IM in a deltoid muscle. Safety and immunogenicity will be evaluated by follow-up visits over the subsequent 24 weeks. The peripheral blood mononuclear cell (PBMC) sample for immunogenicity studies collected at Week 4 after vaccination will be obtained by apheresis if the subject is willing and eligible for apheresis and an apheresis appointment can be conveniently scheduled in the interval specified; otherwise PBMCs will be obtained from 80 mL blood collected by phlebotomy.

Study Duration: Subjects will be evaluated at 6 or more clinical visits for 24 weeks after the study injection.

Study Endpoints: The primary endpoint is safety of the vaccine administered at a dose of 1 x 10(10) particle units (PU) by intramuscular injection. Secondary endpoints are immunogenicity as indicated by HIV-specific antibody and cellular immune responses through Week 6, Ad5 antibody titer at Week 0 and Week 4 and social impact at Week 24. Exploratory analyses of immunogenicity at Weeks 12 and 24, Ad5 antibody titer at Week 24 and epitope mapping of the CD8+ and CD4+ T cell responses at Week 4.

A Phase 1 study testing VRC-HIVADV014-00-VP booster and VRC-HIVADV014-00-VP in people with Healthy and 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 34 inclusion and 26 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 Jul 2017. 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.

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 NCT00102089, which also lists 2 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 2 Jul 2017.
