Active clinical trials for "HIV Infections"

The purpose of this study is to determine whether immunizations with an integrated combination of ALVAC-HIV (vCP1521) boosted by AIDSVAX gp120 B/E prevent HIV infection in healthy Thai volunteers.

This study will investigate the safety and effectiveness of using adefovir dipivoxil (ADV), pegylated interferon (PEG-INF), and ribavirin (RBV) in patients triple-infected with hepatitis B virus (HBV), hepatitis C virus (HCV), and HIV. Patients in this study must be taking lamivudine (3TC).

This study will evaluate the drug telbivudine (LdT) for treatment of hepatitis B virus (HBV) in HIV infected patients. Patients will take telbivudine alone for 24 weeks, add anti-HIV drugs for 24 weeks, then stop taking telbivudine while continuing their anti-HIV drug regimen. To enroll in this study, patients must not be taking any anti-HIV drugs and cannot have taken more than 31 days of treatment with lamivudine (3TC), protease inhibitors (PIs), or nonnucleoside reverse transcriptase inhibitors (NNRTIs).

The purpose of this study is to evaluate the safety of and immune response to an alphavirus replicon, HIV-1 subtype C gag vaccine, AVX101, in HIV uninfected adults in the United States, South Africa, and Botswana.

The purpose of this study is to see if an investigational vaccine can make antibodies (proteins found in blood) in humans that will influence the course of an AIDS-like disease in monkeys. Hopefully, the results of this study can be applied to humans. AIDS, which is caused by infection with HIV, is associated with many deaths and occurrences of disease. Although recent advances have been made in anti-HIV therapy for AIDS, there is no cure for HIV infection or AIDS, and drug therapy is too expensive for most infected populations. Some organizations are trying to make safe and effective vaccines that may prevent HIV infection and AIDS worldwide. Certain vaccines can generate specific antibodies in humans, but they do not inhibit HIV infection in laboratory tests. It is possible, however, that these antibodies may make HIV disease less severe following infection. For this reason, monkeys will be used to evaluate the role of specific human antibodies.

To evaluate the safety and immunogenicity of a combination of microparticulate monovalent HIV-1 MN synthetic branched peptide candidate vaccine for oral administration and monovalent HIV-1 MN synthetic branched peptide vaccine in alum for intramuscular administration in intermediate or higher risk HIV-negative volunteers.

To evaluate the safety and tolerability of the Chiron vaccine human immunodeficiency virus (HIV) p24(25 or 50 micrograms)/MF59 in healthy HIV-1 seronegative adults. To evaluate the immunogenicity of the HIV p24(50 micrograms)/MF59 vaccine.

The purpose of this study is to see if it is safe to give nevirapine (NVP) to breast-feeding babies from birth to the age of 6 months and to determine what dose of NVP should be given. Breast-feeding has been shown to be very important for the physical and mental health of infants. This is especially true during the first 6 months of life. However, an HIV-positive mother can pass the virus on to her baby by breast-feeding. Because of this risk, HIV-positive mothers are encouraged to formula-feed, not breast-feed, their babies. In developing countries, however, some women cannot afford to formula-feed. If they do formula-feed, these women risk exposing their HIV status. These women have great need for methods that can lower the chance that they will pass HIV on to their babies. This study will test NVP as a way of doing this.

The purpose of this study is to see if the vaccines tested are safe when given alone and when given together, and how the immune system responds to the vaccines. Vaccines are given to people to try to prevent an infection or disease. Early testing in a few people has shown that the HIV vaccines ALVAC vCP1452 and AIDSVAX B/B seem to be safe to use.

The purpose of this study is to find out whether or not the addition of hydroxyurea to didanosine (ddI) and other anti-HIV medications will result in better control of HIV infection. The Food and Drug Administration (FDA) has approved ddI for treating HIV infections. Hydroxyurea is approved for treating some cancers and blood disorders. It works against HIV-1 when combined with ddI. Researchers need to look at how well patients may respond to hydroxyurea in combination with ddI and other anti-HIV drugs, and at any side effects.
