The Effects of GLA (5 mcg) on Human Volunteers

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT01864876

Brief Summary:
This protocol is for a phase 1, randomized, single-blinded study to evaluate the safety and tolerability of a single 5 mcg dose of GLA-SE administered intramuscularly and GLA-AF administered subcutaneously. The second focus will be to detail the global immune response by measuring systemic cytokines, chemokines, and global gene regulation. The third focus will be to investigate the effects of GLA on the peripheral blood immune cells including monocytes and dendritic cells. The results of this trial will generate supportive human data to use GLA as an adjuvant in a dendritic cell-targeted vaccine strategy.

Actual Study Completion Date : December 2013

Arm Intervention/treatment
Experimental: GLA-AF
5 mcg GLA-AF given as one subcutaneous injection.
Biological: GLA-AF
Glucopyranosyl Lipid A (GLA) in an aqueous formulation (AF).

Experimental: GLA-SE
5 mcg GLA-SE given as one intramuscular injection.
Biological: GLA-SE
Glucopyranosyl Lipid A (GLA) in a stable oil-in-water emulsion (SE).

Experimental: EM060G (SE)
EM060G (SE) given as one intramuscular injection.
Biological: EM060G (SE)
The same stable oil-in-water emulsion (SE), but without GLA.

Primary Outcome Measures :
  1. Safety [ Time Frame: 1 year ]

    Local reactogenicity events and systemic reactogenicity events will be monitored for 28 days post injection.

    • Local reactogenicity events include tenderness, erythema, skin discoloration, edema, vesicle formation or ulceration, induration, pruritus, formation of a crust or scab, or other.
    • Systemic reactogenicity events include fever, chills, headache, nausea, vomiting, malaise, myalgia, arthralgia, and rash.

    Long term safety will be monitored by follow-up phone calls at 3 months, 6 months, and 1 year post injection.

Secondary Outcome Measures :
  1. Immunogenicity [ Time Frame: 28 days ]
    Describe the global immune response by measuring systemic cytokines, chemokines and global gene regulation. Investigate the effects of GLA on the peripheral blood immune cells including monocytes and dendritic cells.
