Filter by:This is a phase I, single-site, study to evaluate the effects of VOR and HIV-1 Antigen Expanded Specific T Cell Therapy (HXTC) on persistent HIV-1 Infection in HIV-infected individuals suppressed on ART. Twelve participants with durable viral suppression will be enrolled and will complete the study. All participants will receive the same treatment and if eligible, will be dosed with HXTC and VOR. Participants will continue their baseline ART regimen throughout the study.
A Retrospective Study to Evaluate the Safety and Efficacy of a Nucleoside-Sparing Regimen of Darunavir, Ritonavir, and Dolutegravir
Project Narrative This 5-city proposal seeks to address HIV disparities among young (ages 15-24) Black and/or Latinx men who have sex with men (YBLMSM) and transgender women (YBLTW) in a multilevel intervention to identify, engage and retain, high-risk HIV-uninfected and HIV-infected urban YBMSM/TW in the HIV prevention and treatment cascade. The mobile-enhanced engagement intervention (MEI) is driven by the expressed and self-determined needs of each HIV infected and uninfected participant and includes care navigation, engagement, treatment and adherence. MEI also includes a supplemental Screening, Brief Intervention, and Referral for Treatment (SBIRT), to support YBLMSM/TW who face barriers accessing substance use treatment. By building upon existing case management services and flexibility to be adapted across ages and maturity and for prevention services, this intervention has the ability to transform networks, HIV and prevention care in YBLMSM/TW in cities with very high primary and secondary HIV transmission.
This study aims to evaluate the safety, tolerability, pharmacokinetics (PK), and anti-retroviral therapy (ART) activity of monotherapy with MK-8504 (a tenofovir pro-drug), in ART-naïve Human Immunodeficiency Virus (HIV)-1 infected participants. The primary hypothesis is that MK-8504, at a dose that is sufficiently safe and well tolerated, has superior antiretroviral activity compared to placebo, as measured by change from baseline in plasma HIV-1 ribonucleic acid (RNA) at 168 hours post-dose.
The purpose of this study is to evaluate whether maintenance antiretroviral therapy could be simplified to DTG + FTC dual therapy and/or patient-centered monitoring once virological suppression is achieved. Using a factorial design, the study aims to assess the efficacy of DTG + FTC dual therapy to maintain virological suppression through 48 weeks of follow-up as well as the costs of a patient-centered ART laboratory monitoring.
This is a multicentre, phase IV, randomised, open-label, trial exploring adjunctive maraviroc and/or metformin for liver steatosis over 48 weeks. Sponsored by University College London Coordinated by MRC Clinical Trials Unit at UCL
This is a non-inferiority (10% non-inferiority margin), study to assess the efficacy and safety of dolutegravir, DTG (50 mg once daily [QD]) administered in combination with tenofovir alafenamide fumarate, TAF (25 mg QD) and emtricitabine, FTC (200 mg QD) compared to DTG (50 mg QD) administered in combination with tenofovir disoproxil fumarate, TDF (300 mg QD) and FTC (200 mg QD) and compared to efavirenz, EFV (600 mg QD) administered in combination with TDF (300 mg QD) and FTC (200 mg QD) through 96 weeks in patients with HIV-1 starting first-line ART.
The primary objective of this study is to evaluate the efficacy of switching from a regimen of either dolutegravir (DTG) and emtricitabine /tenofovir alafenamide (F/TAF) or DTG and emtricitabine/tenofovir disoproxil fumarate (F/TDF) to a fixed dose combination (FDC) of bictegravir/emtricitabine/tenofovir alafenamide (B/F/TAF) versus DTG+F/TAF in virologically suppressed HIV-1 infected adults with or without antiretroviral (ARV) resistance.
Cotrimoxazole preventive therapy (CPT) is recommended for prevention of morbidity and mortality due to Pneumocystis pneumonia and other infections in HIV positive patients with low immunity. Common clinical practice is to start CPT in any patient with CD4 counts below 200/µL, and, conversely, to stop CPT when immunity has been restored by antiretroviral treatment to CD4 counts above 200/µL or when viral suppression has been documented for 3 months. However, the latest WHO guidelines widely expands the indication for CPT by advocating for settings with high prevalence of malaria and bacterial infections, that all patients with HIV start CPT regardless of CD4 counts and clinical stage. Furthermore, WHO recommends these patients to continue CPT indefinitely regardless of evidence of immune restoration (The recommendation is for settings with high prevalence of malaria and bacterial infections, not for high-income countries). There is limited scientific evidence to recommend prolonged CPT, as studies have shown it is associated with modestly reduced morbidity due to pneumonia, meningitis and malaria, but no corresponding reduction in mortality. The impact of such a large increase in antibiotic use on the emergence of antimicrobial resistance has not been thoroughly considered. Our previous studies in Tanzania showed that multidrug-resistant bacteria frequently cause bloodstream infections with resultant very high case-fatality rates. As genes encoding for multiple antibiotic resistance traits are transferred by plasmids together with resistance towards cotrimoxazole, prolonged CPT will likely favor the selection of carriage of multidrug-resistant gut bacteria. The proposed randomized clinical trial is designed to assess whether prolonged CPT in HIV-positive patients results in increased fecal carriage of multi-drug resistant gut microbes or increased nasal carriage of methicillin-resistant Staphylococcus aureus (MRSA). Secondary endpoints are morbidity (clinical events, hospitalizations) and mortality. Stool specimens, nasal swabs and clinical data will be collected from persons attending voluntary counseling and testing facilities and HIV-clinics in Dar es Salaam, Tanzania. The study results may have important impact on public health in terms of assisting development of rational recommendations for CPT use, and may help prevent emerging antibiotic resistance.
The objective of our project is to determine the infected seminal cell types and the molecular mechanisms involved in HIV cell-associated transmission in the colo-rectal mucosa, using conditions as close as possible to real life, i.e. seminal leukocytes and seminal plasma from HIV-infected donors and tissue explants
