NCT00811954
The U.S. Department of Health and Human Services (HHS) guidelines recommend that HIV infected patients who have never received anti-HIV therapy be treated with a triple drug regimen. The most commonly prescribed and successful regimen contains the medication efavirenz (EFV). However, this regimen may not be an option for everyone, hence alternative regimens are needed. This study was designed to look at how well different combinations of anti-HIV drugs work to decrease the amount of HIV in the blood (viral load) of and allow immune system recovery in people who have never received anti-HIV therapy. This study also examined drug tolerability and safety for the various drug combinations.
NCT00440271
The primary purpose of this study is to: 1. Demonstrate the safety and efficacy of tipranavir/ritonavir (TPV/r) among a racially diverse HIV+ population (males and females) who are three-class (nucleoside reverse transcriptase inhibitor (NRTI), non-nucleoside reverse transcriptase inhibitor (NNRTI), and protease inhibitor (PI)) experienced with documented resistance to more than one PI. 2. Determine pharmacokinetic data in this racially and gender diverse population. 3. Determine the potential utility of using therapeutic drug monitoring (TDM) in improving efficacy outcomes.
NCT00096772
The purpose of this study is to collect blood samples from HIV infected individuals for use in future genetic studies.
NCT00447902
The main purposes of this study are: demonstrate the safety and efficacy of TPV/r among HCV or hepatitis B virus (HBV) co-infected HIV+population, three-class (NRTI, NNRTI, and PI) experienced, with documented resistance to more than one PI. Determine pharmacokinetic data in this co-infected population and potential utility of using therapeutic drug monitoring (TDM) in improving efficacy outcomes.
NCT00784147
The investigational product, ibalizumab, is a humanized IgG4 monoclonal antibody administered via intravenous infusion at 800 mg every 2 weeks or at 2000 mg every 4 weeks. In addition to study drug, all patients will receive an optimized background regimen (OBR), which is a standard-of-care regimen selected by the investigator prior to randomization that is comprised of 2-4 antiretroviral agents. These agents must have been approved by the local regulatory agency or be available through expanded-access programs for treatment of human immunodeficiency virus (HIV).
NCT00381303
The purpose of this study is to evaluate any differences in the effectiveness, safety, and tolerability of PREZISTA (darunavir; DRV) 600 mg, administered with ritonavir (RTV) 100 mg twice a day on virologic response (defined as a viral load (VL) of \< 50 copies/mL) over a 48-week treatment period in HIV-positive women and men. Additional antiretroviral (ARV) agents will also be administered and will be chosen by the Investigator based on resistance testing and prior treatment history (referred to as the Optimized Background Regimen (OBR)).
NCT00385632
The purpose of this study is to compare the effects of two different anti-HIV drug regimens on quality of life and health care utilization among SMART study participants.
NCT00000922
The purpose of this study is to determine whether it is better to start an anti-HIV regimen containing a protease inhibitor (PI), a non-nucleoside reverse transcriptase inhibitor (NNRTI), or a PI in combination with an NNRTI. This study will also examine which treatment regimen is best as a first treatment for HIV infection.
NCT00245739
The purpose of this study is to provide early access to TMC114 (a protease inhibitor) for HIV-1 infected patients with limited or no treatment options, who have failed multiple antiretroviral (ARV) regimens, and to evaluate the longer-term safety and tolerability of TMC114/r in combination with other antiretrovirals
NCT00260806
This study will use the NIH-sponsored Women and Infants Transmission Study (WITS) and the Pediatric Pulmonary and Cardiovascular Complications of Vertically Transmitted HIV Infection (P2C2) HIV-infected pediatric cohorts to determine how left ventricular (LV) function (particularly fractional shortening and contractility) and structure (particularly wall thickness and mass) are affected by cumulative intensity of exposure to highly active anti-retroviral therapy (HAART).
NCT00253682
This study will determine the impact of highly active antiretroviral therapy (HAART) on the developing cardiovascular system, the evolution of HAART-associated cardiovascular changes over time, and the association between cardiovascular measurements with HAART exposure.
NCT00552240
The aim of this clinical trial is to compare the efficacy and safety of ritonavir (RTV)-boosted atazanavir with nevirapine, each on a background of emtricitabine and tenofovir disoproxil fumarate (DF).
NCT00055120
The purpose of this study is to evaluate the effect of starting anti-HIV drugs in HIV infected patients who are being treated for opportunistic infections (OIs). This study will follow two patient groups: those who received anti-HIV drugs soon after being diagnosed with an OI and patients with OIs who deferred beginning anti-HIV drugs until after recovering from the OI.
NCT01422330
The purpose of this study is to learn more about the safety and tolerability of etravirine. Etravirine is a type of non-nucleoside reverse transcriptase inhibitor (NNRTI) which has shown high activity against wild-type human immunodeficiency virus (HIV-1), and HIV strains resistant to other non-nucleotide agents.
NCT00110305
The purpose of this study is to evaluate the dose-response relationship of antiviral activity after 48 weeks treatment with 3 different dose regimens of TMC278.
NCT00001102
The purpose of this study is to see how taking certain anti-HIV drugs affects the way the body metabolizes fat. This study will evaluate patients who are enrolled in CPCRA 058 (the FIRST \[Flexible Initial Retrovirus Suppressive Therapies\] study) by looking for changes in cholesterol levels, levels of fat in the blood, and body fat distribution. Patients in the FIRST study receive an anti-HIV drug regimen which contains a protease inhibitor (PI), a nonnucleoside reverse transcriptase inhibitor (NNRTI), or both. Anti-HIV drug therapy using PIs has become very common treatment for HIV-positive patients. Recently, however, serious side effects involving how the body uses fat are being reported in patients taking PIs. Examples of these side effects are a redistribution of body fat, high cholesterol level, and development of diabetes. However, some of these side effects have also been seen in patients who are not taking PIs. It is important to determine whether or not these side effects are directly related to PI use. In this study, patients on different drug combinations, either with or without a PI, will be compared.
NCT01593046
LAI115428 is a Phase I, randomized, repeat dose escalation study to determine the safety, tolerability, and PK profile of intramuscular and subcutaneous injections of GSK1265744 in a long acting parenteral (LAP) formulation in healthy subjects. Subjects will be randomized to 3 monthly dosing cohorts and 1 quarterly dosing cohort with either intramuscular or subcutaneous dosing. In the monthly dosing cohorts subjects will receive GSK1265744 alone for 2 months and then in combination with TMC278 long acting parenteral (LA) for 2 months. For the quarterly dosing cohort, 2 quarterly intramuscular doses of GSK1265744 LAP will be given alone. Three dose levels of GSK1265744 will be evaluated partly in combination with TMC278 LA to adequately characterize the GSK1265744 LAP and TMC278 LA safety, tolerability, and PK profile. A total enrolment of approximately 40 healthy subjects is planned for this study.
NCT00386035
The purpose of this study is to compare the effects of two different anti-HIV drug regimens on HIV transmission risk behavior among SMART study participants.
NCT01254656
This is a study to assess long-term safety and efficacy of lersivirine in patients who have completed 96 weeks of treatment with lersivirine in studies A5271015 and A5271022.
NCT00993148
The objective of this study is to evaluate the safety and efficacy of a novel combination antiretroviral therapy regimen consisting of maraviroc plus darunavir/ritonavir in treatment-naive patients infected with R5-tropic HIV-1. The hypothesis is that in treatment-naive subjects infected with R5-tropic HIV-1, combination antiretroviral therapy with maraviroc plus darunavir/ritonavir is well tolerated and efficacious.
