NCT00096772
The purpose of this study is to collect blood samples from HIV infected individuals for use in future genetic studies.
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)).
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.
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.
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.
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
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).
NCT00644163
This study will evaluate the effectiveness of a risk-reduction program in preventing the transmission of HIV and sexually transmitted diseases among African-American heterosexual couples, with one partner having been previously diagnosed with an HIV infection.
NCT00074386
With improved anti-HIV drug therapy, HIV infected patients are now living longer. These patients are at risk for liver and kidney failure and may need organ transplants. However, little is know about the safety and effectiveness of organ transplants in patients with HIV. This study will evaluate organ transplantation in HIV infected patients undergoing liver and kidney transplants.
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.
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).
NCT00162227
This study is being conducted to assess the safety and tolerability of an oral liquid solution of Sustiva for antiretroviral therapy-naive or therapy-experienced HIV-1 infected children between the ages 3-16 who are failing or intolerant of current antiretroviral regimen and who are unable to swallow Sustiva capsules.
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).
NCT00624195
CIT2 is a strategy for targeting HAART (Highly Active Antiretroviral Therapy) to the CNS (Central Nervous System) in patients with HIV associated neurocognitive impairment (HNCI). The primary goal of this study is to evaluate the effectiveness of CNS-targeted (CNS-T) as compared to non-CNS-targeted (non-CNS-T) HAART in treating HNCI globally and in different domains of functioning known to be affected by HIV. It is hypothesized that participants in the CNS-T arm will have greater improvement in neurocognitive functioning than those in the non-CNS-T arm. The secondary goal of the study is to compare participants assigned to CNS-T and non-CNS-T HAART on measures of CNS and systemic HIV suppression (undetectable CSF and plasma VL). It is also hypothesized that although CSF viral suppression will be more frequent in the CNS-T arm, plasma viral suppression will be similar in the two treatment arms.
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.
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.
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.
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.
NCT00361101
The purpose of this study is to determine the safety and activity of AMD11070 in HIV-infected patients carrying X4-tropic virus.
NCT00389207
Primary purpose of this study is to compare the efficacy and safety of two different nevirapine (Viramune) dosing regimens (once daily (QD) and twice daily (BID) application) and of atazanavir/ritonavir (Reyataz/Norvir), all on an emtricitabine/tenofovir disoproxil fumarate (DF) (Truvada) background. Patients will receive either nevirapine (NVP) 200 mg twice daily, or NVP 400 mg once daily , or ritonavir-boosted atazanavir (ATZ/r), all in combination with emtricitabine (FTC) and tenofovir DF (TDF). All patients receiving NVP will start at 200 mg once daily for 2 weeks, because it has been demonstrated that this lead-in dosing regimen reduces the frequency of NVP-induced rash. At Visit 3 (Week 2), patients increase the NVP dose to either 200 mg twice daily or to 400 mg once daily. Patients receiving ATZ/r will be treated with ATZ 300 mg once daily, boosted by 100 mg ritonavir (RTV) once daily. Background antiretroviral therapy for all patients consists of one tablet of Truvada. Treatment duration is 48 weeks (primary endpoint) with an extension to 144 weeks. Patients may also participate in the metabolic sub-study, comparing NVP and ATZ/r for signs and symptoms of lipodystrophy and serum lipid/glycaemic abnormalities.
