Filter by:The investigators performed this study to evaluate the safety and feasibility of transplantation with CRISPR/Cas9 CCR5 gene modified CD34+ hematopoietic stem/progenitor cells for patients that develop AIDS and hematological malignances. Patients will be treated with antiviral therapy (ART) to achieve undetectable HIV-1 virus in peripheral blood before conditioning. CD34+ cells from donors will be infused into the patients after treatment with CRISPR/Cas9 to ablate CCR5 gene.
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.
The purpose of this phase III study is to evaluate the efficacy, safety and tolerability of UB-421 monotherapy in suppressing viral rebound in HIV-1 infected adults undergoing antiretroviral treatment interruption.
Open, prospective, multicenter French cohort study enrolling subjects aged of 15 years or more, during or immediately after HIV-1 primary infection. This cohort was organized from the outset to be highly multidisciplinary, bringing together immunologists, virologists, clinicians and epidemiologists.
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 goal of this proposal is to determine the effect of maraviroc when it has been a part of the antiretroviral (ART) regimen given immediately after allogeneic hematopoietic cell transplant (allo-HCT) for HIV-1 infected participants who have a hematopoietic malignancy or other underlying disorder requiring an allogeneic transplant. Maraviroc has been given in practice to alleviate symptoms of graft vs. host disease (GvHD). Given its mechanism of action, it may also have an effect on the reservoir size of HIV-1 in infected patients. This study will inform potential future studies, evaluating the effect of this approach on the incidence and severity of GvHD, and determining its effect on HIV-1 reservoir.
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.
This is an unblinded cluster-randomized study to evaluate the effectiveness of two strategies for scripting/dispensing of antiretroviral therapy (ART) on retention, virologic suppression, and cost compared to the standard of care. The study will be conducted in Malawi and Zambia among approximately 8,200 HIV-1-infected adults (18 years or older) who are stable on ART. Clusters will be randomized to one of three study arms: (1) standard of care (SOC) ART scripting (varies by country, region, clinic, and/or provider), (2) three-month ART scripting, and (3) six-month ART scripting. 30 clusters will be selected for the study, 15 in Malawi and 15 in Zambia, and will be randomized to a study arm.
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.
