Active clinical trials for "HIV Infections"

The abacavir (ABC)/dolutegravir (DTG)/lamivudine (3TC) 600 milligrams (mg)/50 mg/300 mg fixed-dose combination (FDC) tablet is currently approved in the United States (US) and Europe. Although the pharmacokinetics (PK), safety and tolerability of ABC/DTG/3TC FDC tablets have been extensively studied in subjects not of Japanese heritage, these parameters have not been exclusively assessed in Japanese subjects. To support the marketing application in Japan, this single-dose, open-label study will characterize the PK, safety and tolerability of ABC/DTG/3TC FDC tablet in adult Japanese healthy subjects. A maximum of 12 subjects will be enrolled such that approximately 10 evaluable subjects complete the study. The study will consist of a screening, treatment phase (single oral dose under the fasted state) and follow-up visit (within 7-14 days of the last PK sample collected). The total duration of the study for each subject will be approximately up to 48 days.

This study evaluates the efficacy, safety and tolerability of switching from the older, established single tablet regimen of ATRIPLA® (EFV/FTC/TDF) to a new single tablet regimen of BIKTARVY® (BIC/FTC/TAF), in HIV-1 infected adult subjects who are virologically suppressed (HIV-1 RNA<50 copies/mL).

The aim of the study is to determine if treatment for recently acquired hepatitis C infection (with or without HIV coinfection) can be shortened when treating with the interferon-free therapy sofosbuvir/velpatasvir (SOF/VEL). SOF/VEL is a new treatment for hepatitis C called direct acting antiviral which targets the hepatitis C virus replication cycle and has been shown in phase II studies in chronic HCV to be highly effective (SVR12 >95%) when given for 12 weeks. Data has shown that treatment can be shortened when treating recently acquired HCV with interferon containing treatments. It is not known whether treatment with SOF/VEL can be shortened. This study aims to find out if treatment for 6 weeks with open-label SOF/VEL is equivalent to treatment for 12 weeks with SOF/VEL in participants with recently acquired hepatitis C infection. The project is a randomised study where both participants and investigators would not find out the treatment duration of the participants until week 6 of treatment.

Anti-HIV drugs cut down the number of serious infections that people with HIV get. However, some subjects taking anti-HIV drugs do not achieve adequate cluster of differentiation 4 (CD4) recovery and decrease in elevated cluster of differentiation 8 (CD8) cells. Such patients with a low CD4/CD8 ratio remain at risk for developing acquired immune deficiency syndrome (AIDS) and non-AIDS-related complications. Two of the most important factors associated with low CD4/CD8 ratio include: the persistence of HIV on ART and inflammation. Metformin, the most widely used medication to treat type 2 diabetes, is well tolerated with minimal side effects. It has been linked to anti-aging and weight reducing properties in non-diabetic persons. Because of its ability to improve immune functions, metformin could be a promising addition to ART in HIV patients. It is also reported to change the composition of microbes in the gut which may improve inflammation. PURPOSES OF THE STUDY The purposes of this study are to find out if: metformin can be combined with anti-HIV drugs to reduce the amount of hidden virus in the body; metformin can be combined with anti-HIV drugs to improve immune function. metformin can be combined with anti-HIV drugs to impact CD4 T cell count and CD4/CD8 T cell ratio during treatment and after its discontinuation metformin can change the composition of the bacteria in the gut which may improve inflammation. For this purpose, the investigators will add metformin at the usual antidiabetic dose for 12 weeks for patients receiving stable ART, having a CD4/CD8 ratio below 0.7. Approximately 22 participants will be enrolled in this study at the Chronic Viral Illness Service of the McGill University Health Centre, the Ottawa Hospital and the Maple Leaf Medical Clinic (Toronto). This study will last about 24 weeks; metformin treatment will be for 12 weeks. In order to be eligible for the study, the participants must be 18 years of age or older, have an undetectable viral load (the quantity of the HIV virus in the blood must be less than 50 copies/ml) for at least 3 months and have a CD4/CD8 ratio of less than 0.7. All participants will also be asked to give blood and stool samples and optional colon mucosal biopsy samples (before and after metformin supplementation) to study the size of the viral reservoir and the amount of T cell activation and changes in gut microbiota composition.

Combined antiretroviral therapy (cART) efficiently suppress viral replication in majority of AIDS patients. The morbidity and mortality of the disease has dramatically decreased over the past 20 years. However, chronic human immunodeficiency virus-1 (HIV-1) infection lead to profound immune defects in some advanced AIDS patients who often develop with severe opportunistic infections (OIs), severe cachexia and other deadly complications, which accounts for the major death group even under cART. Up-to-date, there are no effective immune interventions to restore host holistic immunity for advanced AIDS patients.

This is a switch study to assess the non-inferiority (in terms of efficacy and safety) of darunavir (boosted with ritonavir, DRV/r 400mg/100mg daily) when compared with lopinavir (boosted with ritonavir, LPV/r total dose 800mg/200mg daily), in combination with a nucleoside backbone, administered as a second line therapy in HIV positive individuals.

48-week open label randomized phase IV investigator initiated intervention study. The purpose of this study is to evaluate whether HIV-1 suppression can be maintained by DTG monotherapy in HIV-1 infected, virologically suppressed patients on cART. 104 adults fulfilling the in and exclusion criteria and on stable cART will be randomized over 2 investigational arms. The first arm will contain the direct switch population. This population will switch directly from stable cART to Dolutegravir mono-therapy on baseline visit. The second arm will contain the delayed-switch population. This group will switch from stable cART to Dolutegravir monotherapy 24 weeks after baseline visit. The main goal is to investigate if Dolutegravir mono-therapy could be non-inferior to cART in virological suppressed HIV-1 infected adults. If a interim analysis (performed when 40 patients on dolutegravir monotherapy have passed week 12) shows that it is safe to continue the study, an additional 30 patients will be included on top of the 104 patients needed for the primary endpoint analysis. In contrast to the primary endpoint population, these additional 30 patients will have a CD4 nadir <200 but a CD4 >350 at the time of the screening visit. Besides that, these 30 patients will have to fulfill all other in and exclusion criteria of the primary endpoint population (specifically a viral load never >100.000). These 30 patients are part of a pilot study looking at the possibility to broaden the eligible population in a future larger randomized clinical trial.

This is a triple cohort, open-label pilot study of the safety and antiviral activity of a single infusion of autologous CD4+ T cells genetically modified at the CCR5 gene by Zinc Finger Nucleases SB-728mR (ZFN Modified CD4+ T Cells) using electroporated mRNA with or without the prior administration of two different doses of cyclophosphamide.

Like most of sub-Saharan Africa, Rwandan youth are the epicenter of the AIDS epidemic, accounting for 40% of new infections. Antiretroviral (ART) adherence is a global health priority, but Rwandan youth are more than twice as likely to be on second line therapy than adults, and with a median population age of 18.7 years old, adherence is essential for Rwanda's future. Resources to provide youth-centered medical and psychosocial care are limited in Rwanda, and young people with HIV face many obstacles to adherence, namely the long-term consequences of genocide, depression, and gender-based violence, as well as logistical issues, negative attitudes, and insufficient parent/caregiver support. Preliminary data underscore the utility of culturally-adapted, trauma-informed cognitive behavioral therapy (TI-CBT) in reducing depression and traumatic distress among youth and adults in Rwanda. This project proposes a 2-arm randomized controlled trial (RCT) to test and compare the efficacy of adherence-enhanced Trauma Informed Cognitive Behavioral Therapy (i.e., TI-CBTe) to usual care in increasing ART adherence among Rwandan youth from two clinics caring for the largest number of youth with HIV in Rwanda. This proposal answers a compelling need for innovative programs to increase ART adherence among HIV+ youth. If effective, the study will build Rwanda's capacity to provide much needed services; and, involvement by the Rwanda Biomedical Center will ensure wide dissemination.

Background: HIV affects millions of people. The disease may "hide" in the brain, even in people with well-controlled HIV without cancer. Then it may "wake up" and continue. The drug pembrolizumab uses the body s immune system to fight cells like cancer cells. It is approved to treat some cancers but not HIV. Researchers want to see if it is safe for HIV-positive people without cancer. This study is not for HIV treatment; only one dose of the drug will be used. Objective: To learn if the drug pembrolizumab, used to treat certain cancers, is safe for HIV-positive people. Eligibility: Adults ages 18 and older with HIV who are in another NIH protocol Design: Participants will be screened with: Medical history Physical and neurological exams Blood tests Lumbar puncture. The lower back will be numbed. A needle will remove fluid from between back bones. FDG-PET/CT. A radioactive sugar will be injected in a thin plastic tube (catheter) inserted in an arm vein. Participants will rest for an hour, urinate, then lie in the scanner. A mask will hold the head still. Leukapheresis. An optional procedure at baseline. White blood cells are removed from you using a serum cell separator machine Women who can become pregnant cannot take pembrolizumab. Men who take it must use 2 kinds of contraception. Participants will have up to 7 more visits, which repeat some screening tests. At 1 visit, participants will get one dose of pembrolizumab by catheter for 30 minutes. They will get allergy and pain medicines. At 2 visits, participants will have a brain MRI. They will get a contrast agent by catheter. They will lie in a metal cylinder that takes pictures for 1-2 hours. They will get earplugs for loud sounds.
