Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of the study is to determine the safety of and immune response to the investigational HIV vaccine, EP HIV-1090, in HIV uninfected adults.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The worldwide HIV/AIDS epidemic may only be controlled through the development of a safe and effective vaccine that will prevent HIV infection. DNA vaccines are inexpensive to construct, readily produced in large quantities, and stable for long periods of time. EP HIV-1090 is a DNA HIV CTL vaccine; the proteins for which its genes code are designed to interact with CD8 cells (CTL) and cause CD8 cell proliferation. The DNA plasmids in EP HIV-1090 code for proteins conserved among HIV subtypes A, B, C, D, F, and G, which encompass the HLA subtypes of 85% of the worldwide general population.

Participants will be enrolled in this study for 1 year. Group 4 participants will receive EP HIV-1090 or placebo at study entry and Months 1, 3, and 6. There will be 11 study visits that will occur at screening; study entry; and Months 0.5, 1, 1.5, 3, 3.5, 6, 6.5, 9, and 12. A physical exam and risk reduction/pregnancy prevention counseling will occur at each visit. Participants will be asked about their adverse experiences from vaccination at each visit. Blood and urine collection will occur at selected visits.
