Raltegravir Intensification in HIV-infected Patients
HIV InfectionsThe purpose of this study is to determine whether treatment with Raltegravir further decreases HIV viral replication in HAART-suppressed, HIV-infected patients, potentially improving immune response to antiretroviral therapy.

KIVEXA Vs TRUVADA, Both Administered With Efavirenz, In ART-Naive Subjects
InfectionHuman Immunodeficiency Virus I1 moreRecently, the fixed-dose combinations (FDC) KIVEXA™ (abacavir/lamivudine) and TRUVADA (tenofovir disoproxil fumarate/emtricitabine) have facilitated the usage of once-daily regimens. However data from head-to-head randomized trials comparing these two FDCs as part of an initial regimen are not available at present. The long-term toxicity profiles of these regimens are of particular importance, as treatment of HIV is currently life-long and therefore, minimizing long-term toxicity and maximizing adherence and duration of regimen maintenance are critical therapy objectives. The primary endpoint is estimated glomerular filtration rate (GFR), as measured by the modified diet in renal disease (MDRD) equation, a validated estimate of renal function.

Durability of Nevirapine-Based Antiretroviral Regimen
HIV InfectionsAlthough nevirapine is used as an alternative to efavirenz for initial regimen in developed countries, nevirapine has still been a key antiretroviral drug in many resource-limited countries including Thailand due to its accessibility and affordability. In addition, a component of stavudine and lamivudine is still widely used as a backbone in the antiretroviral regimen in this setting.To date, data on the durability of a regimen of stavudine, lamivudine and nevirapine are very limited, particularly from the resource-limited settings.

Effect of Maraviroc on Endothelial Function in HIV-Infected Patients
HIV InfectionCardiovascular Disease2 moreThe purpose of this study is to determine the potentially beneficial aspects of CCR5 inhibition on inflammation and endothelial function as measured by brachial artery reactivity in antiretroviral treated HIV patients with an undetectable viral load.

The VMVN Study: Virological Monitoring in Viet Nam
HIV InfectionAIDSThe purpose of the study is to test the hypothesis that the addition of routine viral load testing to the standard laboratory monitoring of HIV patients on first-line antiretroviral treatment (ART) in Vietnam will result in better clinical outcomes for patients.

Ritonavir-Boosted GS-9137 vs. Ritonavir-Boosted Protease Inhibitor(s) in Combination With Background...
HIVHIV-11 moreThe 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.

Study of HIV Patients With Undetectable Viral Load and Abnormal Lipids Switching to Atazanavir/Ritonavir...
HIV InfectionsPatients with HIV who are virologically suppressed on a lopinavir/ritonavir combination highly active antiretroviral therapy (HAART) regimen but with elevated non-HDL cholesterol are randomized to remain on lopinavir/ritonavir or change to atazanavir/ritonavir in combination with current nucleoside reverse transcriptase inhibitors (NRTIs).

A Study on the Safety and Effectiveness of L-756423 Plus Indinavir in HIV-Positive Patients Who...
HIV InfectionsThe purpose of this study is to see if L-756423, an anti-HIV drug, is safe to give with indinavir and if it works well at lowering the level of HIV in the blood (viral load).

A Study to Learn More About MAC Disease and the Use of Anti-HIV Drugs in Patients With Advanced...
Mycobacterium Avium-intracellulare InfectionHIV InfectionsThe purpose of this study is to determine if infection with Mycobacterium avium complex (MAC) occurs in other parts of the body before it is found in the blood. This study also evaluates the relationships between the amount of HIV in the blood, immune system functions, and the presence of MAC infection. HIV-positive patients are at risk for MAC infection because their immune systems have been weakened by HIV. It is hoped that aggressive treatment with anti-HIV drugs may improve their immune systems enough to prevent against MAC.

The Effectiveness of Ritonavir Plus Zidovudine Plus Lamivudine in HIV-Infected Patients
HIV InfectionsTo determine whether administration of a highly active antiretroviral treatment regimen consisting of ritonavir (ABT-538), zidovudine (AZT), and lamivudine (3TC) is associated with the restoration of delayed type hypersensitivity and lymphocyte proliferative responses in patients with moderately advanced HIV-1 infection. To better characterize in these patients the phenotype of the expanded lymphocyte subpopulations, as well as the genotype, phenotype, and cellular origin of viruses that persist after initiation of therapy, and the genotype and phenotype of drug-resistant isolates that emerge during therapy. Although plasma viral load drops dramatically after initiation of powerful antiretrovirals, it does not drop to zero. It appears that a new steady state is reached, suggesting that a reservoir may exist of virus-producing cells, possibly cells of monocyte/macrophage lineage, that continue to produce a low level of virus despite antiretroviral treatment.
