Active clinical trials for "HIV Infections"

Metabolic changes commonly occur in HIV therapy. The purpose of this study is to assess the impact on insulin sensitivity from the administration of tenofovir disoproxil fumarate 300 mg compared with placebo in non-HIV-1 infected healthy adult males. Additionally, endothelial function, adipocytokines and lipids will be monitored.

This study will examine the effectiveness and safety of raltegravir (isentress) when used together with lopinavir/ritonavir (kaletra) for the treatment of HIV-infection. Isentress is a recently, Food and Drug Administration (FDA) approved, HIV medication that has strong effects against the HIV virus. Isentress has been shown in other studies to be safe and well tolerated by HIV patients. Combining this drug with kaletra might enable us to construct a HIV regimen that does not include the more toxic drugs of the nucleoside reverse transcriptase inhibitor class. Eligible volunteers will undergo the following as part of the study procedure: Sign the study consent form and the HIPAA Authorization Form. Two-third of subjects, the intervention group (selected by random chance) will have their HIV drug treatment changed to kaletra + isentress. The other one-third will continue their usual HIV medications (this will be the control group). Make 9 study related visits to the Ponce clinic during the 48 weeks study period. During these visits, medical information will be collected, and blood tests will be performed. Perform Dexa-scan on two separate occasions at Emory University Hospital Radiology. Information collected will be used to assess the effectiveness of this treatment in keeping the HIV virus suppressed, how well these two drugs together is tolerated by HIV-infected patients, and the blood levels of these two drugs when given together.

The purpose of the study is to determine in healthy volunteers whether certain anti-HIV medications (lopinavir/ritonavir and efavirenz) affect the drug levels of certain anti-malarial medications (artesunate/ amodiaquine and artemether/ lumefantrine) and vice versa. Since these drugs are degraded using overlapping pathways in the liver, it is predicted that changes in both drug level and overall drug exposure will be observed.

Hypothesis: Intensification of current ARV regimens with maraviroc will result in more complete suppression of viral replication, particularly in the gastrointestinal mucosa with resultant reduction in markers of immune activation and improved GI immune reconstitution.

This is a pilot that will evaluate two regimens for treating HIV infected patients that haven't been on treatment before. HIV/AIDS patients may have an increased risk of myocardial infarction and antiretroviral therapy used may contribute to this. We will evaluate virological, immunological and cardiovascular effects of two HIV treatment regimens.

The purpose of this study is to determine whether a combination of raltegravir and darunavir is as effective as standard regimens in the treatment of HIV-infected patients who have not previously used antiretroviral drug (treatment naive)

This project involves two studies focusing on the engagement and treatment of adolescents diagnosed with substance use disorders. Study 1 will evaluate a promising parent-based engagement intervention, Community Reinforcement Training, designed to facilitate the entry of resistant drug-abusing adolescents in treatment. The approach will be compared with an Engagement As Usual intervention condition. Study 2 involves a controlled clinical trial evaluating the efficacy of an HIV/AIDS prevention intervention embedded in family-based drug abuse treatment for reducing HIV/AIDS risk behaviors and substance use. Adolescents who are successfully engaged in treatment through Study 1 will be randomly assigned to receive either family therapy alone or family therapy with the integrated HIV/AIDS prevention intervention. Both studies are being conducted in Portland, Oregon.

A phase Ib partially blinded pilot study to evaluate the safety and immunological effects of PENNVAX-B with or without co-administration of constructs containing DNA encoding for the expression of either IL-12 or IL-15. Primary objectives To determine the safety of HIV-1 DNA constructs (PENNVAX-B). To determine the safety and optimal doses of the IL-12 and the IL-15 adjuvant constructs when given with PENNVAX-B. Secondary objectives To compare the various vaccine groups for their immunological responses to several HIV-1 antigens, utilizing the ELISPOT assay. To analyze antibody responses to the vaccine antigens over time. To measure CD8 cell proliferative responses to vaccine antigens over time.

Therapy guidelines recommend the use of either the non-nucleoside reverse transcriptase inhibitor (NNRTI) efavirenz or a ritonavir-boostered protease inhibitor (PI) plus 2 nucleoside reverse transcriptase inhibitors (NRTI) as first-line treatment regimes of HIV-1 infection. Recent clinical studies suggest potential advantages of NNRTI- over PI-based regimes in therapy initiation due to lower rates of virologic failure and less metabolic side-effects. In contrast, PI regimes were claimed to cause greater increases in CD4 cell count than NNRTI regimes, which has been attributed to intrinsic antiapoptotic effects of the PI. However, it is still unclear whether the immunological response to a PI-containing regime is greater than to an NNRTI-containing regime, whether there is a difference in the extent of reduction of apoptosis between PI and NNRTI regimes and whether a difference in apoptosis is associated with a difference in CD4 cell recovery. We conducted a controlled, long-term, random matched pair design study in HIV-1 infected individuals under sustained virologic suppression to evaluate in head-to-head comparison the clinical effects of a constant PI-based or NNRTI-based regime on CD4 cell recovery and the underlying molecular, biochemical and functional mechanisms.

LC002 is an experimental therapeutic vaccine designed to boost the immune response of people infected with HIV. The purpose of this study was to determine the safety and tolerability of and immune response to LC002 in HIV-1-infected adults who are currently receiving anti-HIV treatment.
