NCT02073656
This study will evaluate the antiviral efficacy, safety, and tolerability of ledipasvir/sofosbuvir (LDV/SOF) fixed-dose combination (FDC) administered for 12 weeks in hepatitis C virus (HCV) treatment-naive and treatment-experienced (including treatment intolerant) participants with chronic genotype 1 or 4 HCV infection who are co-infected with HIV-1. Participants who experience confirmed post-treatment virologic failure (relapse) at or before Posttreatment Week 24 may be eligible to be enrolled in the Retreatment Substudy to receive LDV/SOF plus ribavirin (RBV) for 24 weeks.
NCT00665353
Insulin resistance is common in people coinfected with HIV and Hepatitis C virus (HCV) and is associated with poor responses to treatment for HCV. Pioglitazone is an FDA-approved medication for the treatment of type 2 diabetes. It works by increasing the body's sensitivity to insulin. The purpose of this study is to determine whether treatment with pioglitazone prior to HCV treatment with peginterferon and ribavirin is safe and effective in improving the treatment outcome in insulin-resistant, HIV/HCV-coinfected people for whom previous treatment with peginterferon and ribavirin was unsuccessful.
NCT00118898
Currently, the preferred anti-HIV regimens used in the United States consist of two nucleoside reverse transcriptase inhibitors (NRTIs) and the nonnucleoside reverse transcriptase inhibitor (NNRTI) efavirenz (EFV). However, with new anti-HIV drugs being approved, alternative regimens need to be tested to determine if new drug combinations have increased effectiveness in treating HIV. The purpose of this study is to test the safety, tolerability, and effectiveness of four different regimens in HIV-infected adults who have never taken anti-HIV drugs.
NCT02167386
Black men who have sex with men (MSM) have among the highest rates of new HIV infections of any group in the United States. Developing effective HIV prevention interventions that work with this group is a critical element of the National HIV/AIDS Strategy. In the first phase of our study ("the ethnographic phase"), the investigators will carry out community-based research that will explore structural, social and cultural factors relevant to how Black MSM might engage with Pre-Exposure Prophylaxis (PrEP). This phase of community-based research will inform the design of an enhanced PrEP adherence intervention, which will be subsequently tested at a community-based health clinic in Harlem in the second phase of the project.
NCT00094523
This study was designed to evaluate and compare safety, tolerability of subjects who successfully suppress HIV-1 on their first PI regimen to those who switch to fosamprenavir. This is a 48-week study, where subjects who were assigned to be in their original PI-group have the option of switching to fosamprenavir on week 24. Prior to being assigned their treatment group, subjects had to be suppressed for at least three months. All subjects also take a background regimen of two nucleoside/nucleotide reverse transcriptase inhibitors.
NCT02578706
Advances in antiretroviral therapy (ART) have resulted in increased survival of the HIV-infected population; however, this gain in longevity is associated with an increased risk of cardiovascular disease (CVD). Although ART and traditional risk factors contribute to CVD in this population, heightened markers of immune activation, inflammation, and coagulation independently predict morbidity and mortality, suggesting that dysregulation of these systems plays a significant role in the increased risk of CVD. The investigators believe that platelet activation is an important driver in HIV-associated immune activation, inflammation, and coagulation, leading to an increased CVD pathophysiology and risk. Platelets initiate thrombus formation and also play a key role in vascular inflammation by releasing pro-inflammatory mediators and cross-talking with other relevant cell types including leukocytes. Researchers have described platelet hyperreactivity in chronic HIV infection. Importantly, the investigators demonstrated that one week of anti-platelet therapy (aspirin) decreased platelet activation and immune activation, with an improved trend in inflammation and immune parameters. The overall hypothesis is that platelet activation is a major driver of immune activation, inflammation, and thrombosis in ART-treated HIV infected patients. The purpose of the proposed proof-of-concept study is to understand the mechanism(s) by which anti-platelet therapy improves immune and inflammatory parameters in chronic HIV infection. To test this, the immune modulating and anti-inflammatory effects of 24 weeks of the anti-platelet drug aspirin as compared to the anti-platelet drug clopidogrel will be evaluated. Given their different mechanisms of action and inhibitory potency, the investigators can differentiate whether the potential benefits are mediated via inhibition of arachidonic acid (aspirin) or inhibition of ADP (clopidogrel) or by the antithrombotic activity. A secondary goal is to perform multidimensional assays of platelet activity and thrombogenicity alongside immune activation assays and careful assessments of traditional risk factors and medication regimens, to understand which parameters are highly associated with thrombogenicity.
NCT02076178
This study is a Phase IIa, randomized, multi-site, two-arm, double-blinded study to evaluate the safety, tolerability, and acceptability of GSK1265744 long acting injectable formulation (744 LA) in adult male subjects. To evaluate the safety and tolerability of the injectable agent, 744 LA (800 milligrams (mg) dose administered at three time points at 12 week intervals) through Week 41 in HIV-uninfected men. Eligible participants will be randomized in a 5:1 ratio to receive 744 LA or matching placebo. Participants will receive daily oral 744 (30 mg tablets) or matching placebo for 4 weeks during the Oral Phase of the study, followed by a one week washout period. Following safety lab assessments from the Oral Phase, participants will enter the Injection Phase and receive Intramuscular (IM) injections of 744 LA or placebo at three time points at 12 week intervals. IM injections will consist of 800 mg of 744 or a matching control
NCT00855335
The purpose of this study is to study how changes in the body during pregnancy influence the blood levels of TMC114 (darunavir) and ritonavir taken together, darunavir and cobicistat taken as a fixed-dose combination, TMC125 (etravirine) taken alone or with darunavir and ritonavir or rilpivirine in patients with human immunodeficiency virus-1 (HIV-1). This study will examine how these drugs are absorbed in the body, how they are distributed within the body and how they are removed from the body over time. Any pregnant woman who is currently receiving darunavir with ritonavir, darunavir with cobicistat, etravirine or rilpivirine for HIV-1, and who meets the eligibility criteria for the study, will be allowed to enroll. Patients must be willing to remain on study medication during the course of their pregnancy, and 12 weeks postpartum. The information collected may help answer questions about how to best prescribe these three drugs for pregnant women.
NCT03109743
The investigators will conduct a pilot randomized controlled trial (RCT) of Sisters-GPS with HIV-positive women of color with suboptimal ARV adherence and detectable HIV viral loads (VL). Participants will be randomized to Sisters-GPS (intervention involving weekly group clinical visits for seven weeks plus social media website) or appointment with an adherence counselor (a minimum of 3 visits) (control condition). Data sources will include interviews, medical and pharmacy records, and blood samples. The primary outcome will be ARV adherence at the completion of the intervention assessed via pill count. The secondary outcome will be HIV VL suppression.
NCT02782130
This is a two-arm, randomized-controlled trial (RCT) that will test the acceptability, impact, and long-term sustainability of the Epic Allies intervention application (app), a theory-based mobile app that utilizes game mechanics and social networking features to improve engagement in care, antiretroviral therapy (ART) uptake, ART adherence, and viral suppression among HIV-positive young men who have sex with men (YMSM) and trans women who have sex with men. Subjects will be randomized to either the intervention branch of the Epic Allies app or the control branch of the app.
NCT01449929
This study will be conducted in approximately 468 HIV-1 infected antiretroviral therapy (ART)-naïve subjects. Subjects will be randomized 1:1 to receive dolutegravir (DTG) 50 mg once daily (approximately 234 subjects) or darunavir/ritonavir (DRV/r) 800 mg/100 mg once daily (approximately 234 subjects), each in combination with fixed-dose dual nucleoside reverse transriptase inhibitor (NRTI) therapy (either abacavir/lamivudine (ABC/3TC) or tenofovir/emtricitabine (TDF/FTC). Subjects will be stratified by screening HIV-1 RNA and background NRTI selection. The primary analysis will take place after the last subject completes 48 weeks on therapy; an additional analysis will be conducted after the last subject completes Week 96 on study.
NCT01092611
The purpose of this long-term follow-up study is to assess the long-term health status of HIV-infected subjects who previously participated in GSK-sponsored trials evaluating the investigational HIV vaccine 732462. This study will provide additional data concerning the long-term benefits/risks associated with vaccination. No vaccine will be administered during the study period. Vaccines were administered during the primary studies.
NCT01967940
The primary objective of this study is to evaluate the efficacy of tenofovir alafenamide (TAF) versus placebo, each administered with the existing, failing antiretroviral (ARV) regimen. There are 2 parts to this study: Part 1 and Part 2. Part 1 consists of 2 cohorts, starting with a sentinel cohort, in which participants will be enrolled to receive open-label TAF in addition to their current failing ARV regimen. This cohort will then be followed by a randomized, double-blind, cohort to compare the addition of TAF or placebo in HIV-1 positive adults who are failing their current ARV regimen. In Part 2, all participants who complete Part 1 of the study will discontinue their failing ARV regimen and TAF or placebo for a 14-day washout period. Following the washout period, all participants who received TAF in Part 1 and have a \> 0.5 log10 decline in HIV-1 RNA will receive elvitegravir/cobicistat/emtricitabine/tenofovir alafenamide (E/C/F/TAF) single-tablet regimen (STR) plus atazanavir (ATV) once daily for 48 weeks. Participants who received TAF who have a ≤ 0.5 log10 decline in HIV-1 RNA will be discontinued from the study and will not be eligible to continue into Part 2 of the study. All participants who received placebo in Part 1 will be eligible to participate in Part 2 regardless of their viral load change. After completion of Part 2, all participants will be eligible to continue to receive E/C/F/TAF plus ATV in the extension phase until E/C/F/TAF becomes commercially available, or until Gilead Sciences terminates development of E/C/F/TAF in the applicable country.
NCT01543958
HIV-infected people can have an increase in inflammation in their body organs, even after taking anti-HIV medicines. Sevelamer carbonate is used to bind phosphate in dialysis patients. It can also bind endotoxin in the gut and lowers endotoxin levels in the blood of dialysis patients. Sevelamer carbonate decreases the inflammation endotoxin causes in dialysis patients. A5296 is a phase II, single-arm study to evaluate the effect of 8 weeks of sevelamer carbonate administration on markers of microbial translocation and T-cell activation in the blood in chronically HIV-infected subjects not receiving ART.
NCT00414635
For people with HIV who are currently taking specific medications (including Sustiva (efavirenz)) and have no detectable viral load, this study tracks how patients do if they take their medications for five days of the week compared with seven days of the week.
NCT00931801
The purpose of this Phase IV pilot study is to evaluate the safety, tolerability, and satisfaction of a nucleoside analog reverse-transcriptase inhibitors (NRTI)sparing regimen for participants fully suppressed on an atazanavir/ritonavir based highly active antiretroviral therapy (HAART)regimen plus emtricitabine/tenofovir (Truvada). Several pharmacologic factors support this concept including the favorable drug interaction between atazanavir and raltegravir. Participants will be randomized to either continue on their current regimen or one of two study arms (atazanavir 300mg plus ritonavir 100mg daily plus raltegravir 400mg twice daily or atazanavir 300mg twice daily plus raltegravir 400mg twice daily). Participants will be followed for 48 weeks for safety, tolerability, and satisfaction. After baseline, the participants will have six clinic visits for evaluation and labs.
