NCT02345252
The primary objective of this study is to evaluate the noninferiority of switching to emtricitabine/rilpivirine /tenofovir alafenamide (FTC/RPV/TAF) fixed-dose combination (FDC) as compared to continuing FTC/RPV/tenofovir disoproxil fumarate (TDF) FDC (FTC/RPV/TDF) in virologically suppressed HIV-1 infected participants.
NCT00082628
The primary objective of the study is to determine if Serostim® 4 mg administered daily for 12 weeks as treatment for the abnormal fat accumulation and distribution associated with HIV-associated Adipose Redistribution Syndrome (HARS) reduces Visceral Adipose Tissue (VAT, measured by CT scan) more effectively than placebo.
NCT02706717
The purpose of the study was to evaluate whether the probiotic Visbiome Extra Strength reduces inflammation in HIV-infected men and women when compared to a placebo (inactive medication like a dummy pill). The study evaluated whether taking Visbiome Extra Strength by mouth for 24 weeks was safe and well-tolerated for HIV-infected persons on antiretroviral therapy (ART). Probiotics are germs such as yeast or bacteria that are found in food and supplements that are used to improve the health of the digestive system. Many people refer to probiotics as "helpful bacteria." These bacteria live in the body and help the body work normally. In some medical conditions, including HIV infection, helpful bacteria are replaced with bacteria that can change the normal intestinal function and increase inflammation. The investigators tested whether giving a probiotic restored normal intestinal function and decreased inflammation.
NCT02263326
HIV-1 infected subjects with CD4 nadir \> 200 cells/mm3, no history of virologic failure and plasma HIV RNA \<50 copies/mL for at least 48 weeks while on any United States Department of Health and Human Services (DHHS) recommended or alternative three-drug antiretroviral regimen will be randomized to dolutegravir (DTG) plus lamivudine (Arm 1) or continuation of their current regimen (Arm 2) for 48 weeks. The primary endpoint is virologic failure defined as confirmed plasma HIV-1 RNA \> 50 copies/mL before or at Week 24
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.
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.
NCT02128217
Early identification of acute HCV infection is essential to prevent chronic infections and the long-term liver disease complications that may occur. Early identification and treatment of HCV during the acute phase can result in significantly higher response rates with shorter durations of therapy. Pegylated-interferon alfa (PEG-IFN) was the typical treatment for HCV infection. Participants subcutaneously inject PEG-IFN where the average duration of treatment was approximately 20 weeks. With the advancement of direct-acting antivirals (DAAs), it was possible to see if a new DAA might be non-inferior compared to (PEG-IFN). The study was designed to see if a fixed-dose combination tablet can replace the old HCV treatments by being more effective, safer and better tolerated in HIV-infected participants with new HCV infection. The study was a Phase I, open-label, two cohort clinical trial, in which 44 acutely HCV-infected HIV-1 positive participants were enrolled. Participants in each cohort were evaluated in two steps: on treatment (Step 1) and follow-up after discontinuing study treatment (Step 2). The cohorts were enrolled sequentially. Participants in Cohort 1 were enrolled and administered oral Sofosbuvir (SOF) in combination with weight-based ribavirin (RBV). Participants in Cohort 2 were enrolled and administered an oral fixed dose combination of Ledipasvir/Sofosbuvir (LDV/SOF).
NCT00340548
Background: Over 80% of the hemophiliac population who became infected with HIV prior to 1985 are also co-infected with HCV. Thus, hemophiliacs represent an important population for studies of the natural history of these chronic viral infections. Moreover, the high rate of co-infection makes it an ideal group for assessing the interaction between the viruses and the relationship between viral specific immune responses and clinical progression. Although the hemophiliac poulation is unique, co-infection by these chronic viral pathogens is becoming increasingly common, particularly amongst intravenous drug users, who account for approximately 25% of the HIV-1 epidemic in the United States. Objectives: The aim of this study is to determine if polymorphism in the promoter region of TH1 and Th2 cytokines are associated with (1) intracellular cytokines levels in CD4 + Tcells, (2) Human Immunodeficiency Virus (HIV) and Hepatitis C virus (HCV) viral loads, and (3) clinical progression of HIV1 to AIDS in hemophiliacs. Eligibility: The current proposal will investigate host genetic factors related to HIV-1 and HCV immunopathogenesis by studying children and adolescents enrolled in the Hemophilia Growth and Development Study (HGDS). Design: This study is in collaboration with the principle investigators of the Hemophilia Growth and Development Study (HGDS) as part of a grant "Pathogenesis of HIV and HCV in Hemophilia: HGDS-3" with funding support by NIH/NICHD for the period 9/25/01 through 8/31/2005. This multicenter, United States study represents a well-characterized, prospectively followed cohort of HCV-infected hemophiliacs, of whom 207 are HIV-1 co-infected. Enrollment of the hemophiliac cohort was completed between 3/89 and 6/90. The final observation of the cohort (follow-up 16) was concluded during 7/98. No new samples or clinical data will be collected on this population. The LGD plays two roles in this project: (1) an administrative role overseeing the withdrawal, handling, and transport of samples from the HGDS/LGD and central repositories at the NCI-Frederick, and (2) a scientific role continuing investigations to determine the role of host genetic factors in Th1 and Th2 immune response and regulation of HCV and HIV viral replication..
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.
NCT00316589
The purpose of this study is to gather information on the safety and immunogenicity of an investigational smallpox vaccine in HIV infected populations. Subjects will receive two vaccinations
NCT01705574
The primary objective of this study is to evaluate the efficacy of a regimen containing elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in HIV-1 infected, antiretroviral treatment-naive adult women.
NCT01769469
This is a prospective observational cohort sub-study of subjects enrolled in the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) 110 (NCT01772823) or ATN 113 (NCT01769456), which is a prospective interventional trial.
NCT01751646
This is a 48 week randomized double-blind, placebo-controlled prospective cohort study of adolescents and young adults with HIV infection in the Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) who are currently being treated with cART that includes tenofovir disoproxil fumarate (TDF) as one component of the regimen that includes at least three Food and Drug Administration (FDA)-approved antiretroviral (ARV) drugs for at least 180 days.
NCT00103532
Risk behaviors and their associated adverse health outcomes are becoming increasingly problematic among HIV-infected youth. This study is being conducted to test whether a brief motivational enhancement (ME) intervention will help reduce health risk behaviors (drug and alcohol use, sexual risk behavior, poor adherence to medications) among HIV+ youth.
NCT01177059
The purpose of this Observational Study is long term follow-up of the Human Immunodeficiency Virus -1 (HIV-1) infected patients who have received a gene therapy product (anti-HIV-1 Ribozyme \[OZ1\]) as part of an earlier phase 2 trial. Patients are seen twice yearly until 5 years from initial infusion of study drug has elapsed and then yearly until withdrawal or study completion. The study will monitor for and record any ill effects from the gene therapy product to provide long term safety information.
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.
NCT00084136
This study compared 3 different three-drug combinations in HIV infected individuals starting their first HIV treatment regimens. Participants were recruited from resource-limited areas in Africa, Asia, South America, Haiti, and also from the United States. The study hypothesis was each of the once daily combinations (PI based, or NNRTI based) would not have inferior efficacy compared to the twice daily NNRTI based combination.
NCT02415595
The purpose of this study is to find at least one dose of BMS-955176 that will be safe, effective and tolerable for HIV-1 infected treatment naive adults.
NCT01721109
The primary objectives of this study are to evaluate the steady-state pharmacokinetics (PK) and confirm the dose of the elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (EVG/COBI/FTC/TDF) single-tablet regimen (STR) (Part A) and to evaluate the safety and tolerability of EVG/COBI/FTC/TDF STR through Week 48 (Part B) in HIV-1 infected, antiretroviral (ARV) treatment-naive adolescents. A total of 50 adolescent participants (12 to \< 18 years of age) will be enrolled to receive EVG/COBI/FTC/TDF as follows: * Part A: Twelve to 16 eligible participants will be enrolled to evaluate steady-state PK, and confirm the dose, with the intent to enroll at least 4 participants 12 to \< 15 and at least 4 participants 15 to \< 18 years of age. * Part B: Following confirmation of EVG exposure in at least 12 participants from Part A, 34 to 38 participants in addition to those enrolled in Part A will be enrolled to evaluate the safety, tolerability, and antiviral activity of EVG/COBI/FTC/TDF STR.
