Filter by:Genital herpes (HSV-2) is the most common cause of genital sores worldwide, and the presence of genital sores is a significant risk factor for becoming infected with HIV. This study will test the effectiveness of twice-daily dosing of acyclovir, a commonly prescribed anti-herpes drug, in preventing HIV infection in HSV-2 infected women who sleep with men (WSM) and men who sleep with men (MSM). Study hypothesis: Given that genital herpes is a significant risk factor to HIV acquisition, twice-daily HSV-2 suppressive therapy - 400 mg of acyclovir - will prevent HIV infection among high risk, HSV-2 seropositive WSM and MSM.
This study will test the immune system response to and safety of two HIV vaccines alone and in combination: ALVAC-HIV (vCP1452) and LIPO-5. ALVAC-HIV (vCP1452) uses a canarypox virus with man-made parts of HIV attached to it. The canarypox virus cannot cause disease in people. LIPO-5 is a mixture of five man-made proteins similar to proteins found in HIV. These vaccines are not produced from live HIV or from infected cells and do not contain the virus. It is not possible to become infected with HIV from these vaccines.
The effectiveness of a vaccine can be improved by using a "prime boost strategy" or by using an adjuvant. A prime boost strategy is the administration of one type of vaccine (the primer) followed by the administration of another type vaccine (the booster). An adjuvant is a substance that can enhance the immune response when given at the same time as a vaccine. This study will evaluate the safety of and immune response to a vaccine designed to be used as part of a prime boost strategy. The study will also evaluate the vaccine when given with an adjuvant. The vaccine in this study is not produced from live HIV or from infected cells. It does not contain HIV, and it cannot cause HIV infection.
The purpose of this study is to compare the effectiveness of anti-HIV drug regimens with or without a protease inhibitor (PI) in HIV infected adolescents. It will also determine if monitoring drug levels and adjusting the dose as necessary improves the effectiveness of these regimens.
The purpose of this study is to determine whether a simplified lopinavir-ritonavir based therapy will continue to keep the viral load to very low levels after initial treatment with a combination of Kaletra® (lopinavir/ritonavir) plus Combivir® (lamivudine/zidovudine).
The purpose of this study is to characterize the quality of life (QOL) and longitudinal patterns of change in QOL outcomes in children and youth with HIV infection; to identify demographic, social, disease status, treatment, and health care utilization factors that predict longitudinal changes in outcomes; to develop a conceptual model that characterizes the effects of specific factors that predict longitudinal changes in QOL; and to characterize the influence of HIV symptoms on QOL outcomes in the domains of health perceptions, physical, psychological, and social role functioning.
Microbicides are drugs that destroy microbes such as viruses and bacteria. Rectal microbicides may be able to prevent transmission of HIV during anal intercourse. The purpose of this study is to obtain rectal samples from men to learn information that may be valuable in future clinical trials of rectal microbicides.
The purpose of this study is to determine the safety and efficacy of administration of a cell-delivered ribozyme gene transfer product to participants with chronic (lasting a long time) Human Immunodeficiency Virus Type 1 (HIV-1) infection (a life-threatening infection which you can get from an infected person's blood or from having sex with an infected person).
This study will determine whether anti-HIV drugs can prevent the sexual transmission of HIV among couples in which one partner is HIV infected and the other is not.
The majority of HIV infected people worldwide became infected with the virus through heterosexual contact. BufferGel and PRO 2000 Gel are vaginal gels designed to prevent women from becoming infected with HIV during sexual intercourse with an HIV infected partner. This study will test the safety and effectiveness of these gels.
