Filter by:The purpose of this study is to find out if there are any bad effects when BufferGel or PRO 2000/5 Gel are applied to the penis of HIV-infected men. Microbicides are products to be used by women for placing into the vagina to prevent passing HIV from 1 person to another during sex. Studies have shown 2 investigational microbicides, BufferGel and PRO 2000/5 Gel, to be safe and acceptable for women and HIV-negative men. It is important to see if the side effects of these products are the same in men as those in women and to see if there is any difference in the side effects between circumcised and uncircumcised men.
Interleukin-2 (IL-2) helps the body make infection-fighting white blood cells, including CD4 and CD8 T cells. One HIV treatment strategy is planned treatment interruption (stopping anti-HIV drugs when CD4 count and level of virus in the blood are at certain levels). The purpose of this study is to see if IL-2 used with potent anti-HIV drugs allows for longer HIV treatment interruptions.
The purpose of this study is to see whether metformin alone, rosiglitazone alone, or metformin and rosiglitazone together will lower insulin levels in the blood and decrease fat in the abdomen or other parts of the body. Studies have shown that certain anti-HIV medications can cause a number of side effects, including high blood sugar (resulting from the body's failure to use insulin), high insulin, and excess fat build-up in the abdominal area. These side effects are known to increase the risk of heart disease. Metformin and rosiglitazone are 2 drugs that have been shown to lower insulin resistance and lessen abdominal fat in patients who are not HIV-infected. This study will investigate the use of these drugs in HIV-infected patients.
This study will test the safety and effectiveness of a new treatment for hepatitis C (HCV) in patients who also have HIV. The usual treatment for HCV in people who are not HIV-infected is interferon-alfa (IFN) with ribavirin (RBV), an approved treatment by the Food and Drug Administration (FDA). This study will use a new, longer acting form of IFN called PEG-IFN alfa-2b. PEG-IFN alfa-2b is approved by the FDA for use in treating HCV but has not yet been approved for use with RBV. This study also will use IL-2, which is a substance that the body naturally produces. People with HIV infection usually do not make enough IL-2. IL-2 is being tested in this study to see if it will "boost" the immune system's response to HCV. The FDA has approved IL-2 for the treatment of some cancers.
ACTG 388 was a clinical trial that compared three- and four-drug anti-HIV drug regimens and demonstrated the effectiveness of a three-drug regimen. This study will compare the ability of two different three-drug anti-HIV drug regimens to reduce levels of HIV in the blood. The study will also evaluate whether patients discontinue the regimens because of drug side effects.
The purpose of this study is to compare immune system activity in young people and older people who do not have HIV. This information will be compared to that of HIV patients in another study. Aging affects immune system activity. This study will look at some of the factors involved. HIV also affects immune system activity. The results from this study, using healthy volunteers, will be compared to those in another study of HIV-infected patients. This may provide information on immune system activity in aging and HIV.
The purpose of this study is to see if the full daily dose of Combivir (zidovudine [ZDV]/lamivudine [3TC]) taken once a day is as effective as the usual recommended twice-a-day dose. Studies have shown that the antiviral activity of ZDV can continue in the body even after there does not appear to be any ZDV left in the blood. This occurs because the body breaks down the drug into substances that remain active against HIV. The body also breaks down 3TC, a drug that is combined with ZDV in the Combivir product, in a similar way. Since antiviral activity may continue after Combivir is removed from the body, it may not be necessary to take the drug as often as once thought. This study carefully measures levels of the active substances in order to find out whether the same amount of antiviral activity occurs with less-frequent dosing.
The purpose of this study is to compare the effectiveness of treatment with BMS-232632 to that of efavirenz (EFV) when both are used with zidovudine (ZDV) and lamivudine (3TC).
The purpose of this study is to determine if 2 doses of Pneumococcal Conjugate Vaccine (PCV) followed by 1 dose of Pneumococcal Polysaccharide Vaccine (PPV) in HIV-infected children on anti-HIV therapy is helpful and safe in fighting pneumococcal infections in this group of children. This study will also look at the protection provided by childhood vaccination against measles, pertussis, and hepatitis B virus. Pneumococcal infections are the most common AIDS-related infection in HIV-infected children. PCV may help reduce the chances of HIV-infected children getting pneumococcal infections. This study will look at whether pneumococcal vaccines are safe and effective in HIV-infected children receiving HAART. It will look at whether HIV-infected children are protected by childhood vaccines received previously and if more doses are safe and improve protection.
The purpose of this study is to determine if HIV-specific canarypox vaccine and/or interleukin-2 (IL-2) will control viral load (amount of HIV in the blood) after HIV treatment is withdrawn for a certain time period.
