NCT00775424 · Status: COMPLETED · Phase: PHASE1 · Type: INTERVENTIONAL · Enrollment: 38

Last updated 2016-08-25

No results posted yet for this study

Summary

A phase Ib partially blinded pilot study to evaluate the safety and immunological effects of PENNVAX-B with or without co-administration of constructs containing DNA encoding for the expression of either IL-12 or IL-15.

Primary objectives

1. To determine the safety of HIV-1 DNA constructs (PENNVAX-B).
2. To determine the safety and optimal doses of the IL-12 and the IL-15 adjuvant constructs when given with PENNVAX-B.

Secondary objectives

1. To compare the various vaccine groups for their immunological responses to several HIV-1 antigens, utilizing the ELISPOT assay.
2. To analyze antibody responses to the vaccine antigens over time.
3. To measure CD8 cell proliferative responses to vaccine antigens over time.

Conditions

  • HIV Infection

Interventions

BIOLOGICAL

PENNVAX-B

PENNVAX-B is a cocktail of three expression plasmids. The plasmids include the genes which encode a synthetic HIV-1 envelope protein (pEY2E1-B), Gag (gagCAM02), and Pol (pK2C1). Each plasmid is manufactured to a concentration of 4.0 mg/mL and is formulated with bupivacaine (0.25%) as a facilitating agent for DNA uptake. All plasmids (2.0 mg each gag, pol, env) are premixed by the manufacturer in the same vial.

BIOLOGICAL

GENEVAX IL-12-4532

GENEVAX IL-12-4532 This molecular adjuvant plasmid contains nucleotide sequences necessary for expression of the human IL-12 protein. IL-12 DNA is formulated at a concentration of 2.0 mg/mL with bupivacaine (0.25%).

BIOLOGICAL

PLACEBO

PLACEBO

BIOLOGICAL

IL-15 adjuvant

pIL15EAM is a plasmid that encodes human IL-15 and has been optimized to express 87 fold higher than native IL-15 DNA and 5.7 fold higher than an earlier generation optimized IL-15 DNA construct. This plasmid is formulated at a concentration of 4.0 mg/mL with bupivacaine (0.25%).
