Filter by:The goal of the project is to determine the difference in immune activation and HIV reservoir size between People living with HIV (PWH) on tenofovir-containing antiretroviral therapy (ART) versus PWH on nucleoside reverse transcriptase inhibitor (NRTI)-sparing ART. Tenofovir (TFV), a phosphonated nucleoside reverse transcriptase inhibitor (NRTI), is being used for oral pre-exposure prophylaxis (PrEP). The investigators will test this hypothesis: tenofovir, and perhaps NRTIs in general, stimulate a type I/III interferon also in PWH who take these drugs. Because chronic interferon stimulation may promote the survival and proliferation of cells with integrated provirus, the investigators also hypothesize that these drugs antagonize decay of the HIV latent reservoir in PWH on ART. Consequently, the researchers hypothesize that PWH who have switched from NRTI-containing ART to NRTI-sparing ART exhibit lower type I/III interferon pathway activation and lower latent HIV reservoir size. The investigators also hypothesize that independently of treatment, the extent of type I/III interferon activation correlates with latent HIV reservoir size. Thus, the proposed study seeks to answer these two questions. Can the gastrointestinal epithelium be impacted by ART, and contribute to chronic immune activation and expansion of the HIV-1 reservoir? If so, what therapeutic approaches can the investigators implement to reduce the HIV-1 proviral load? The data will reveal pathways that can be targeted therapeutically to treat chronic immune activation in PWH. The findings of this study will immediately translate to optimize the standard of care in PWH.
Background: People with HIV usually take a combination of 2 or more anti-HIV drugs daily to help manage their infection. Sometimes, however, HIV becomes resistant to these drugs, and the infection cannot be treated. Untreated HIV infection can make people more vulnerable to other infections as well as some cancers. Better treatments are needed for people with drug-resistant HIV. Objective: To see if a study drug (UB-421) is effective in people with drug-resistant HIV. Eligibility: People aged 18 years and older with HIV that is resistant to anti-HIV drugs. Design: Participants will be in the study for 35 weeks. Participants will have separate screening and baseline visits within 2 months of each other. They will have a physical exam with blood and urine tests both times. On the second visit, they will undergo apheresis: Blood will be drawn from a needle in one arm. The blood will pass through a machine that separates out the white blood cells. The remaining blood will be given back through a second needle in the other arm. Participants will begin receiving the study drug 1 week after their baseline visit. UB-421 is given through a tube attached to a needle placed in a vein in the arm. They will return for UB-421 treatments every week for 26 weeks. Each visit will take 3 to 6 hours. Participants will have 2 follow-up visits 4 and 8 weeks after their last treatment with UB-421. Apheresis will be repeated at 1 of these visits.
IMPALA is a randomized, open-label, multicenter, interventional study of 540 virologically suppressed HIV-1 infected adults who have a history of sub-optimal adherence to daily oral ART and/or engagement in HIV care. The study will seek to demonstrate non-inferior antiviral effectiveness of the 2-monthly long-acting injectable combination of cabotegravir/rilpivirine as compared to continuation of first line oral antiretroviral therapy.
AHORA is designed as a single-arm, open label, non-comparative, real-world prospective, observational study evaluating the outcomes for viral control and CD4 recovery/immune reconstitution in predominantly Hispanic/Latinx patients of the Rio Grande Valley (RGV) with advanced HIV who are rapidly initiated on bictegravir/emtricitabine/tenofovir alafenamide (Biktarvy) at Valley AIDS Council (VAC) dba Westbrook Clinic (WBC). This research will help to fill data gaps still present for Biktarvy in a rapid start setting among an Hispanic/Latinx population, including those with advanced HIV.
Purpose: The purpose of the project is to determine oral pre-exposure prophylaxis (PrEP) preference among 14-24-year-old adolescent girls and young women (AGYW) at risk of HIV infection and to evaluate a peer support intervention aimed at improving uptake of and adherence to oral PrEP. Main Study Aims: i) To determine oral PrEP preference among 14-24-year-old AGYW at risk of HIV infection in Kampala, Uganda . ii) To evaluate a peer support intervention aimed at improving uptake of and adherence to oral pre-exposure prophylaxis (PrEP), the only currently available biomedical HIV prevention method in Uganda. Study Objectives: i. To determine oral PrEP preference among 14-24-year-old AGYW in Kampala, Uganda, and determine factors associated with preference for oral PrEP. ii. To evaluate the effect of a peer support intervention on uptake of and adherence to oral PrEP among 14-24-year-old AGYW at risk of HIV infection in Kampala, Uganda. iii. To evaluate the effect of a peer support intervention aimed at improving oral PrEP uptake and adherence, on sexual behavior and reproductive health outcomes among AGYW in Kampala, Uganda. iv. To explore AGYW perceptions and experiences of the peer support intervention aimed at improving oral PrEP uptake and adherence. Design Objective 1: A retrospective cohort study of data collected from January 2019 to December 2020. Objectives 2-4: An individually randomized controlled trial with 1:1 randomization in the intervention and control arms. Population: 14-24-year old AGYW at risk of HIV infection in Kampala. Control arm: Standard health worker counselling during clinic visits. Intervention arm: Standard health worker counselling and peer support groups over the weekend.
Phase IV, open-label, single arm, unicenter and pilot study on virologically suppressed HIV infected adults with ETR resistance, to assess the efficacy of a Switch strategy from Etravirine (ETR) to Doravirine (DOR).
The goal of this clinical study is to learn more about the effects of switching to the study drugs, bictegravir (BIC) plus lenacapavir (LEN), versus current therapy (Phase 2) and BIC/LEN fixed-dose combination (FDC) versus current therapy (Phase 3) in people living with HIV (PWH).
Among heavily treatment experienced people living with HIV, the virologic effectiveness of ibalizumab + optimized background regimen from two clinical trials will be compared to non-ibalizumab-containing regimens in routine clinical care in the OPERA cohort.
HIV CoCo is a European multi-centre, multi-country, retrospective, observational case-control study that will aim to describe clinical outcomes and identify risk factors for People Living With HIV (PLWHIV) who are co-infected with the SARS-CoV-2 coronavirus. The study will address two central questions: 1. Is there a particular risk for COVID-19 in PLWHIV as compared to HIV seronegative control COVID-19 cases? 2. Are there particular factors, within the group of PLWHIV, which put them at risk for a more severe COVID-19 disease course? The study will address these questions by recruiting patients co-infected with both HIV and SARS-CoV-2 and comparing them to two control groups - one group infected with SARS-CoV-2 only and another group infected with HIV only. Only deidentified, real-world retrospective data will be used for the study, collected as part of standard, routine clinical care. Additionally, this study will also look to: 1. Describe the differences in the clinical manifestation of COVID-19 in PLWHIV compared to HIV seronegative controls 2. Describe the response to treatment, including supportive care and novel therapies against COVID-19, including antiviral or immunomodulatory therapy 3. Describe the co-morbidities in PLWHIV and controls with COVID-19 4. Compare the severity of COVID-19 between PLWHIV and the COVID-19 only controls at diagnosis and hospital admission. Data will be collected about patient outcomes from COVID-19 (including hospitalisation for COVID-19, length of stay in hospital, critical care admission, ventilation/oxygenation requirements, and need for kidney replacement therapy), as well as pre-existing health conditions, and relevant blood results at COVID-19 diagnosis.
The clinical study is designed to evaluate the ability of two priming vaccine regimens to activate and induce the maturation of cross-reactive CD4 binding site (CD4-bs) antibodies, including VRC01-class antibodies. VRC01- class antibodies are highly desirable to elicit via vaccination because they have broad cover all clades of HIV and passive administration of VRC01 monoclonal antibodies has been demonstrated to prevent acquisition of susceptible HIV strains in clinical trials. The study will assess whether B cells expressing VRC01-like B cell receptors proliferate following immunization with a 'germline-targeting' recombinant Env immunogen. The study will also test whether an immunization strategy based upon fractionated dose delivery of the immunogen may improve the maturation of VRC01-class B cells when compared to traditional bolus dosing. In addition, the study will test whether alterations in the dose of the subsequent boost immunizations affects VRC01-class B cell activation and the rate of antibody affinity maturation.
