NCT00001117
This study evaluates patients infected with both HIV and Hepatitis C virus (HCV) who are receiving anti-HIV drugs. The purpose of this study is to learn more about HCV infection in patients whose HIV blood level decreases to less than 500 copies/ml.
NCT00006643
The purpose of this study is to find if the Single Photon Emission Computed Tomography (SPECT) scan is as effective as a liver biopsy (using a special needle to remove tissue from the liver) in examining liver damage in patients with HIV and hepatitis C virus (HCV). A standard way to examine the liver for disease has been to perform a liver biopsy. The SPECT scan, which takes a picture of the liver, has been found to be effective in determining liver damage but studies need to be done in patients with hepatitis. This study will compare the effectiveness of the liver biopsy and SPECT scan in determining liver disease in patients with HIV and HCV. The SPECT scan might be a good replacement for the liver biopsy if it is found to be as good as or better than liver biopsies.
NCT00001109
The purpose of this study is to learn more about some of the immune cells in the blood (CD4 cells, for example) of healthy children in order to better understand the differences in the blood cells of children infected with HIV. Because children's bodies are still developing, their cells are different from those of adults, and their bodies respond differently to infections such as HIV. In order to understand how immune cells grow and mature so that they can fight HIV, it is important to see how these cells behave in normal children.
NCT00298350
The purpose of this study is to evaluate the non-inferiority of ritonavir-boosted GS-9137 relative to a ritonavir-boosted Comparator Protease Inhibitor when used as part of combination antiretroviral regimens in subjects who have failed, or are failing, protease inhibitor therapy.
NCT00365612
To compare the effectiveness (efficacy, safety \& tolerability) of a Single Tablet Regimen of efavirenz/emtricitabine/tenofovir DF to subjects continuing on unmodified HAART as measured by the proportion of patients who maintain viral load (HIV-1 RNA) \<200 copies/mL at Week 48.
NCT00642499
The primary purpose of this study is to determine if dronabinol is effective in preventing or treating nausea caused by HAART (highly active anti-retroviral therapy) in HIV and AIDS patients
NCT00002168
The purpose of this study is to compare the safety and effectiveness of two anti-HIV drug combinations when given to HIV-infected patients who have never been treated with anti-HIV drugs. One drug combination is stavudine (d4T) plus didanosine (ddI) plus Crixivan. The other combination is Retrovir (AZT) plus Epivir (3TC) plus Crixivan.
NCT00032721
This study will investigate the use of Reiki, an energy-based complementary and alternative medicine (CAM) intervention, as an approach to improve well-being for patients with advanced AIDS, and evaluate its effects on dimensions of well-being and quality of life.
NCT00214747
This study is designed to assess the distribution and spread of four different vehicle formulations in the vagina. In-vivo data will be obtained regarding each vehicle formulation at various time points after insertion of the gel into the vagina.
NCT00214812
This study will assess the distribution of a microbicidal gel in the vagina and confirm the presence of bare spots. MRIs will be done with and without the addition of the MRI contrast Gadolinium to the microbicide in order to determine whether the bare spots are an artifact of the MRI technique.
NCT00002057
To determine a safe, effective, and convenient dosing schedule for nystatin pastilles in the prevention of oral candidiasis in patients with AIDS or AIDS related complex (ARC) (group III or IV, CDC classification).
NCT00002274
The objective of this open-label study regimen is to make didanosine (ddI) available to patients with AIDS who are clinically deteriorating on zidovudine (AZT) and cannot enter the Phase II ddI programs due to protocol exclusion or geographic location.
NCT00002293
To determine a safe, effective, and convenient dosing schedule for nystatin pastilles in the prophylaxis of oral candidiasis in patients with AIDS or AIDS related syndromes (group III or IV, CDC classification)
NCT00002028
The objective of this treatment IND protocol is to make didanosine (ddI) available to patients with HIV infection (suffering from AIDS related complex (ARC) or AIDS) who have developed documented intolerance to zidovudine (AZT) and cannot enter a Phase II ddI program due to protocol exclusion or geographic location.
NCT00038519
The purpose of this study is to study the safety and efficacy of Amprenavir/ritonavir or saquinavir/ritonavir in HIV infected patients that have failed Kaletra as their second protease inhibitor based HAART.
NCT00023348
Primary Objectives: 1\) To determine the proportion of patients with HIV-related tuberculosis who have abnormal pharmacokinetic parameters for isoniazid and rifabutin. Secondary Objectives: 1. To determine risk factors for abnormal pharmacokinetic parameters for isoniazid and rifabutin. 2. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the occurrence of toxicity attributed to antituberculous therapy. 3. To evaluate the correlation between pharmacokinetic parameters of isoniazid and rifabutin and the efficacy of TB therapy. 4. To define and correlate phenotypic INH acetylator status with the results of genotypic acetylator data obtained in the parent trial.
NCT00124358
The purpose of this study is to assess the feasibility, cost and effectiveness of interventions designed to integrate buprenorphine treatment for opioid dependence into HIV primary care in ten HIV care centers in the U.S.
NCT00038636
The purpose of this study is to determine the safety and effectiveness of a high dose of ABT-378/ritonavir
NCT00121979
Racivir ® (RCV) is an experimental drug which means it is not approved for use by the United States Food and Drug Administration (FDA), but it can be used in research studies like this one. RCV (Racivir®) is part of a class of drugs known as "Nucleoside Reverse Transcriptase Inhibitors" (NRTIs), which are intended to block a further increase in the amount of HIV virus in the body. Laboratory research suggests that RCV (Racivir®) may be effective in patients who have developed resistance to other NRTIs, particularly 3TC (lamivudine, Epivir®). However, a study of RCV (Racivir®) has not been done with patients who have previously been treated with other HAART (Highly Active Antiretroviral Therapy -- taking multiple HIV drugs at once) medications including 3TC (lamivudine, Epivir®). The purpose of this study is to evaluate the safety and effectiveness of RCV (Racivir®) when used together with other HIV drugs in people who have previously been treated with 3TC (lamivudine, Epivir®) and are failing with their current HAART treatments. This study will include a total of 60 HIV infected, HAART-experienced subjects currently receiving 3TC (lamivudine, Epivir®) as part of their HAART therapy. The study will take place at approximately 11 study sites in the US and Latin America.
NCT00561496
This is a multi-center, pharmacokinetic study involving a single-dose phase, a wash out phase and a two-week once or twice-daily dosing phase for each of 49 volunteers. In the single-dose phase, each volunteer will apply the single dose in the clinic. Participants will be randomized to have cervicovaginal samples and biopsies collected at one of seven time-points \[0.5, 1, 2, 4, 6, 8, and 24 hour(s)\] after the single-dose. Blood samples will be drawn at 0.5, 1, 2, 4, 6, 8, and 24 hour(s) after the single-dose. In the two-week phase, the study supplies will be distributed and the participants will be randomized to apply each dose either once or twice-daily for two weeks. At the one week follow-up visit a blood sample will be drawn prior to the morning dose to obtain a trough value and cervicovaginal samples will be collected four hours after the morning dose. At the two week follow-up visit blood samples will be drawn prior to the morning dose to obtain a trough value and then at 0.5, 1, 2, 4, 6, 8, and 24 hour(s) from the final morning dose. Participants will be randomized to have cervicovaginal samples and biopsies collected at either 4, 8 or 24 hours after the final morning dose. Up to 10 participants who have completed the first two phases of the study, will be asked to participate in a third phase to have cervicovaginal samples, biopsies and blood samples collected 12 hours after a single-dose.
