NCT00851799
The U.S. Department of Health and Human Services (HHS) guidelines recommend that HIV-infected people who have never received anti-HIV therapy be treated with a triple drug regimen (commonly called combination antiretroviral therapy, cART). Since the introduction of cART, morbidity and mortality among HIV-infected patients has been dramatically reduced. However, metabolic, skeletal, and cardiovascular diseases have been increasingly reported among HIV-infected patients and may be attributable, in part, to the direct effects of cART. Much of our understanding of the development of these diseases, risk factors, and consequences of these disorders has been derived from clinical studies of HIV-infected persons receiving older antiretroviral agents. A5260s was designed to examine the contributions of HIV-disease related factors and impact of newer antiretroviral drugs on the development of metabolic (such as blood vessels, blood sugar, cholesterol), skeletal, and cardiovascular diseases in people who have never received anti-HIV therapy. A5260s is a prospective substudy of a phase III randomized clinical trial A5257 (see ClinicalTrials.gov identifier: NCT00811954). A5257 was designed to look at different combinations of anti-HIV drugs that do not contain the medication efavirenz (EFV) and how well these drug combinations work to decrease the amount of HIV in the blood and to allow immune system recovery in people who have never received anti-HIV therapy. A5257 also examined drug tolerability and safety for the various drug combinations.
NCT00040157
To determine safety and efficacy of ACH-126,443 on the treatment of adults with HIV infection who have modestly detectable viral load while on stable triple combination antiretroviral therapy including 3TC.
NCT01252940
The purpose of this randomized, open-label, multicenter, active-controlled Phase 3b study is to evaluate the noninferiority of the emtricitabine/rilpivirine/tenofovir disoproxil fumarate (FTC/RPV/TDF) single-tablet regimen (STR; also referred to as fixed-dose regimen or fixed-dose tablet) relative to regimens consisting of a ritonavir-boosted protease inhibitor (PI+RTV) and two nucleoside reverse transcriptase inhibitors (NRTIs) in virologically suppressed, HIV-1 infected subjects. The FTC/RPV/TDF STR could offer an attractive treatment option to patients who wish to simplify dosing by reducing pill burden or to improve the tolerability of their treatment. Participants will be randomized into 2 groups, the FTC/RPV/TDF STR group, in which participants will switch treatment regimens at the start of the study, and the Stay on Baseline Regimen (SBR)/Delayed Switch group, in which participants will remain on their baseline regimen during the first 24 weeks of the study (designed to provide an initial active control), and may switch to the FTC/RPV/TDF STR at the Week 24 visit. After the 48-week study analysis period, participants may continue to receive the FTC/RPV/TDF STR per protocol before switching to a commercially available source.
NCT00233883
The purpose of this study is to evaluate the tolerability of a subcutaneous needle-free injection device used to administer Fuzeon, compared with the standard needle/syringe supplied with commercial Fuzeon. The anticipated time on study treatment is \<3 months, and the target sample size is \<100 individuals.
NCT00110877
Study TMC114-C214 is a randomized, controlled, open-label trial to compare the efficacy, safety and tolerability of TMC114 boosted with low dose ritonavir (RTV) versus Kaletra (LPV)/RTV in lopinavir-naïve treatment-experienced HIV-1 infected patients.
NCT01303575
This study will evaluate the effect of an American Indian/Alaska Native (AI/AN) adaptation of the It's Your Game…Keep It Real (IYG) intervention, relative to a comparison condition on sexual behavior outcomes and psychosocial variables for middle school aged youth (12 - 14 years old). The original IYG program was designed for students in Houston middle schools to help students delay sexual initiation and if sexually active, use condoms and contraception. The present study will adapt the existing IYG program for an AI/AN youth cohort; the original IYG curriculum will be transferred into a web-based format and modified to incorporate additional culturally-relevant components. The primary hypothesis to be tested is: (1) students who receive the web-based curriculum will delay sexual activity relative to those who receive standard care. The major dependent variable is the proportion of students initiating sexual activity. Secondary hypotheses will examine the effect of the web-based curriculum on specific types of sex and psychosocial variables related to sexual risk-taking behavior. This project will also examine the effect of the intervention on the proportion of students who are sexually active, number of times students engage in unprotected sexual intercourse, and students' number of sexual partners.
NCT00050089
This 'pragmatic' trial is a 2X2 open randomized study of patients in advanced HIV disease who have failed on conventional Highly Active Antiretroviral Therapy (HAART) regimens including all three classes of anti-HIV drugs. The first randomization will allocate patients to an intended 3-month antiretroviral drug-free period (ARDFP) or No ARDFP. The second randomization will allocate patients to Mega-ART (5+ drugs) or to Standard-ART (up to 4 drugs). The total study duration is 6.5 years with 5 years of intake and 1.5 year (minimum) of follow-up; median duration of patient follow-up is about 4 years. The target sample size is 390 patients and will provide 75% power to detect a 30% reduction in the hazard rate for the primary endpoint with mega-ART. Sixty-four sites will be participating in the trial--24 VA, 19 UK and 21 Canada.
NCT01044654
This research study is being carried out to study a new way to possibly treat HIV. This agent is called a "Zinc Finger Nuclease" or ZFN for short. ZFNs are proteins that can delete another protein named CCR5. This CCR5 protein is required for certain types of HIV (CCR5 tropic) to enter into and infect your T-cells. T cells are one of the white blood cells used by the body to fight HIV. The most important of these are called "CD4 T-cells." Some People are born without CCR5 on their T-cells. These people remain healthy and are resistant to infection with HIV. Other people have a low number of CCR5 on their T-cells, and their HIV disease is less severe and is slower to cause disease (AIDS). Even with no detectable levels of HIV in the blood, HIV remains in some tissues in the body, primarily the gut tissue. HIV infects the CD4+ T-cells including in the blood and gut. The new treatment to be studied will involve removing white blood cell from the blood that contains CD4+ T-cells. The extracted CD4+ T-cells are then genetically modified by the ZFNs to be resistant to infection by HIV by removing the CCR5 gene from the surface of the CD4+ T cell where HIV enters the cell. Additional genetically modified cells are manufactured and then re-infused back into you. Researchers hope that these genetically modified cells will be resistant to infection by HIV and will be able to reproduce additional resistant CD4+ T-cells in your body. Laboratory studies have shown that when CD4+ T-cells are modified with ZFNs, HIV is prevented from killing the CD4+ T-cells. On the basis of these laboratory results, thre is the potential that ZFNs may work in humans infected with HIV and improve their immune system by allowing their CD4+ T-cells to survive longer. The purpose of this research study is to find out whether "zinc finger" modified CD4+ T-cells are safe to give to humans and find how "zinc finger" modified T-cell affects HIV.
NCT00002336
To determine whether clarithromycin is safe and effective in preventing disseminated Mycobacterium avium Complex in HIV-infected patients with CD4 counts \<= 100 cells/mm3.
NCT00762892
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.
NCT01853917
The purpose of this study is to evaluate why the majority of HIV infected women in the Harris County Health District system who are pregnant do not come to clinic for their HIV disease after they have a baby through questionaires administered prepartum and questionaires and structured interviews postpartum. The study will ask subjects questions about HIV, drug use, depression and social problems.
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.
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.
NCT00487188
To assess the efficacy of enfuvirtide (Fuzeon) added to HAART compared to treatment with HAART alone in achieving and maintaining viral load suppression.
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.
NCT01332227
The purpose of this study is to determine whether HIV-1-infected patients, who are virologically suppressed on a regimen of 2 nucleoside reverse transcriptase inhibitors plus any third agent but are experiencing safety and/or tolerability issues, will maintain virologic suppression after switching to a regimen of heat-stable ritonavir boosted atazanavir, 300/100 mg, once daily plus raltegravir, 400 mg, twice daily.
NCT00159224
This study will assess the safety, tolerability and antiviral activity of a simplified PI-based treatment regimen (Kaletra,ä) compared to conventional HAART regimens in patients infected with HIV-1 who are on their first boosted-PI antiretroviral treatment regimen. The potency of the antiviral activity of Kaletra has been clearly demonstrated in a wide spectrum of patients in a number of different clinical trials.6-9 The durable viral suppression seen after 4 years of therapy10 proves that it can provide effective, long-term treatment for people with HIV-1. Data from one of these trials (M97-720),6 an ongoing Phase II study of lopinavir/ritonavir in combination with NRTIs suggests there may be a role for monoclass therapy with Kaletra in the treatment of HIV-1-infection.
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.
