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 vaccine that is effective against multiple strains of HIV remains the best option for preventing the spread of HIV. Plasmid DNA vaccines are inexpensive and easy to construct. When DNA vaccines are administered in combination with cytokines, such as IL-12 or IL-15, the immune response to the vaccine is increased. The purpose of this study is to determine the safety and tolerability of the DNA plasmid vaccine, PENNVAX-B when administered alone, or with IL-12 or IL-15 DNA adjuvants. The most effective and safe dose of IL-15 will also be determined during this study.

This study will last approximately 12 months. Participants will be randomly assigned to one of four groups. Group 1 will receive an injection of PENNVAX-B combined with 0.8 mg IL-15 in each deltoid or placebo. Group 2 will receive an injection of PENNVAX-B alone or placebo. Group 3 will receive an injection of PENNVAX-B combined with IL-12 in each deltoid or placebo. Group 4 will receive PENNVAX-B combined with 2 mg IL-15 or placebo. Injections will occur at study entry, Months 1, 3, and 6. Additional study visits will occur on Days 14, 42, 98, 182, 273, and 364. At these visits a brief physical, blood collection, interview, and risk reduction counseling will occur. At some visits HIV testing, urine collection, and pregnancy tests will also occur.

As of 05/30/08, participants will be enrolled into Groups 3 and 4 at a limited pace to allow for additional safety reviews for the first few participants in these groups. Additionally, safety data will be reviewed for Groups 1 and 2 to determine whether the remainder of participants in Groups 2, 3, and 4 will be enrolled.

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.
