Study of PENNVAX™-B (Gag, Pol, Env) + Electroporation in HIV-1 Infected Adult Participants (HIV-001)

November 8, 2012 updated by: Inovio Pharmaceuticals

A Phase I, Open Label Study to Evaluate the Safety, Tolerability and Immunogenicity of PENNVAX™-B (Gag, Pol, Env) + Electroporation in HIV-1 Infected Adult Participants

DNA vaccines consist of small pieces of DNA also known as plasmids, and have several potential advantages over traditional vaccines. Thus far, DNA vaccines appear to be well tolerated in humans. We have developed DNA vaccine, PENNVAX-B, which includes plasmids targeting the gag, pol, and env proteins of HIV-1. The vaccine will be delivered via electroporation (EP) which uses the CELLECTRA constant current device to deliver a small electric charge following injection, since animal studies have shown that this delivery method increases the immune response to vaccine. The vaccine will be given to HIV-1 infected subjects whose viral load is undetectable on a HAART regimen, with CD4 lymphocyte count above 400 cells/µL of blood. It is hypothesized that PENNVAX-B + EP will be safe and well tolerated.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

A single group of approximately 12 HIV-infected subjects will receive a 4 dose series of PENNVAX-B containing 3 mg of DNA/dose at study entry (Day 0), Week 4, 8, 16 and will be followed for a total of 48 weeks.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 50 years (Adult)

Accepts Healthy Volunteers

No
