Active clinical trials for "HIV Infections"

The purpose of this study is to determine the safety of and immune response to an adenoviral vector HIV vaccine or a DNA HIV vaccine, each followed by an adenoviral vector HIV vaccine boost, in HIV uninfected adults.

Anti-HIV drug regimens have dramatically improved the rates of prevention of mother-to-child transmission (MTCT) of HIV in developed countries. However, little is known of the effectiveness of such regimens in developing countries, such as Botswana. This study will determine whether Trizivir (TZV), a single pill containing abacavir sulfate, lamivudine, and zidovudine (ABC/3TC/ZDV), or lopinavir/ritonavir (LPV/r) and lamivudine/zidovudine (3TC/ZDV) is more effective in reducing HIV-1 viral load and preventing MTCT among HIV infected pregnant women in Botswana.

This study is aimed at demonstrating whether or not Male Circumcision can be used as an effective public health prevention tool that will have an impact on HIV prevalence in the South African population.

Intramuscular (IM) administration of HIV lipopeptide vaccines have been shown to be able to induce HIV-1-specific T cell-mediated immune responses. The objective of this trial was to evaluate the safety and immunogenicity of LIPO-4 vaccine (HIV lipopeptides including 4 peptides from Gag, Pol, RT and Nef HIV-1 proteins, each peptide linked to TT) intradermally (ID) compared to IM administration.

The purpose of this study is to test the safety of and immune response to an HIV-1 vaccine, VRC-HIVADV014-00-VP, when given as a vaccine booster to HIV uninfected adults who participated in HVTN 052.

Pregnant women infected with HIV who take anti-HIV medications during pregnancy lower the risk of passing HIV to their infants. This study will compare how well two different combinations of anti-HIV medications control HIV in pregnancy, and whether these combinations of drugs are effective in preventing HIV from being transmitted from a pregnant woman to her baby. The two combinations are abacavir/lamivudine/zidovudine (ABC/3TC/ZDV) and zidovudine/lamivudine (ZDV/3TC) plus lopinavir/ritonavir (LPV/RTV).

The purpose of this study is to determine the safety and immune system response to the TBC-3B HIV vaccine when it is injected either into the groin area or into the arm. The goal is to determine which injection site is better at producing a particular type of immune response. This study is not evaluating the effectiveness of the vaccine, so volunteers must maintain low risk behavior for HIV transmission throughout the study.

To study the pharmacokinetic properties, safety and viral resistance pattern of the combination of tenofovir disoproxil fumarate and emtricitabine in HIV-1-infected pregnant women and their newborns, with a view to prevention of mother-to-child transmission (PMTCT) of HIV-1 in Africa and Asia.

This study will evaluate the effectiveness of Stepping Stones, an HIV-prevention education program, versus a brief HIV-focused intervention, in improving sexual health and preventing HIV infection in young residents of rural South African communities.

This Phase I trial will assess the feasibility of using a vaginal ring to deliver the candidate microbicide dapivirine (TMC120) for 7 days. The study population will consist of 13 healthy, sexually abstinent women. Safety and tolerability will be assessed through clinical and laboratory assessments. Feasibility of drug delivery will be assessed by measuring dapivirine (TMC120) concentrations in vaginal fluids, vaginal and cervical epithelial tissue, and plasma.
