Filter by:The main purpose of this study is to compare two different types of HIV treatments, in terms of effectiveness and improvement of side effects, for patients who are diagnosed with a more advanced HIV infection. Patients with advanced HIV infections are otherwise known as 'late presenters'. There are many effective treatments for HIV available; however, for late presenting patients the investigators do not know which type of treatment performs best. This is the first large study to compare treatments for patients in this situation, and the investigators hope that the results of this study will help doctors decide which treatments to use in the future. The two different types of treatment the investigators are comparing both contain a mixture of drugs that work together to combat HIV: The Boosted Protease Inhibitor combination (PI) which is a combination tablet containing: darunavir, cobicistat, emtricitabine and tenofovir alafenamide. It was approved for use in Europe under the brand name Symtuza®. The Integrase Inhibitor combination (INI). Which is a combination tablet containing: bictegravir, emtricitabine and tenofovir alafenamide. This is a a newer combination which was approved for use in Europe in June 2018 under the brand name of Biktarvy®. The main difference between the two treatments is how each one fights a HIV infection. They both stop a part of the virus from working (i.e. inhibit it), to prevent it from making copies of itself. The PI treatment contains drugs to stop the protease part of the virus, whereas the INI treatment contains drugs to stop the integrase part. In recent studies, it appears that treatments containing integrase inhibitors may be better for late presenting patients. They have been shown to quickly bring down the amount of virus in the body, and the side effects may be more acceptable to late presenters. To compare the two treatments, half of the participants on this study will be given the PI treatment, and the other half will be given the INI treatment.
First-line antiretroviral regimens are highly efficacious and generally well tolerated. However, as these regimens need to be taken life-long, there is growing concern about long-term toxicities associated with these regimens. Thus, there is great interest from participants and clinicians in unique regimens that might avoid such toxicities by minimizing the number of antiretrovirals without sacrificing long-term antiviral efficacy. DTG plus 3TC is a novel, well-tolerated first-line regimen for HIV-infected treatment- naive participants, limiting the risk of many common adverse reactions associated with other antiretroviral drugs. Thus, this study is designed to evaluate the efficacy and safety of DTG/3TC as a FDC, in ART-naive HIV-1-infected adolescents, who weigh at least 25 kilograms (kg). The study will consists of Screening Phase (up to 28 days prior to the first dose of drug) followed by Treatment Phase (up to 48 weeks). Participants who successfully complete 48 weeks of therapy and who continue to receive benefit from DTG/3TC FDC may enter a 96 weeks study Extension Phase. Study participants who have successfully completed both the Treatment Phase through 48 weeks and the Extension Phase through 144 weeks and continue to receive benefit from this two-drug regimen will continue to receive DTG/3TC FDC in a Continuation Phase (after Week 144) until: DTG and 3TC are both locally approved for use as part of a dual regimen and the single entities of DTG and 3TC are available to participants (e.g. through public health services), or the DTG/3TC FDC tablet, if required by local regulations, is locally approved and available (e.g. commercially or through public health services), or the participant no longer derives clinical benefit or the participant meets a protocol-defined reason for discontinuation. All participants will receive the FDC of DTG/3TC (50/300 milligrams) for once daily. Approximately 30 participants will be enrolled in the study.
This is a non-randomised, controlled, parallel group, sub-study of D2EFT (NCT03017872), a randomised, open-label study in approximately 1,000 HIV-infected adults failing first-line antiretroviral therapy (ART) in low-middle income countries. The sub-study will be offered to all D2EFT sites with access to DXA technology for whole-body composition analysis. Sites will offer the sub-study to consecutive clinic patients. Patients must be approached for participation and provide informed written consent prior to randomisation into D2EFT. This study will recruit approximately 300 patients. Allocation to one of three ART treatment regimens will follow the result of D2EFT randomisation. The study will investigate the role of contemporary ART on body composition and metabolic parameters by comparing over 96 weeks the effects of the D2EFT ART regimens. The primary endpoint will be assessed at week 48.
The proposed research will conduct a fully-powered efficacy trial of this approach in areas with large populations of AA and H/L MSM and high HIV incidence: Jackson, MS, Los Angeles, CA, and Boston, MA. High-risk MSM who have not tested for HIV in the last year will be recruited from MSM-oriented "hook-up" mobile apps, and assigned to receive either (1) HBST with post-test phone counseling/referral ("eTEST" condition), (2) "standard" HBST without active follow-up, or (3) reminders to get tested for HIV at a local clinic ("control" condition) at three month intervals over the course of 12 months. The investigators will explore the impact of the eTEST system on key outcomes, including rates of HIV testing, receipt of additional HIV prevention services, and PrEP initiation, compared with standard HBST or clinic-based testing reminders alone. The investigators will also explore the cost effectiveness of the eTEST system under various scenarios compared with relying on traditional, clinic-based testing alone.
This phase II clinical trial studies the side effects of pomalidomide and how well it works in treating patients with Kaposi sarcoma and human immunodeficiency virus (HIV) infection. Biological therapies, such as pomalidomide, may stimulate the immune system in different ways and stop tumor cells from growing and it may also block the growth of new blood vessels necessary for tumor growth.
Participating countries: Belgium Context: In June 2013, WHO notified that "a single dose of YF vaccine is sufficient to confer sustained life-long protective immunity against YF disease and that a booster dose is not necessary". . For HIV infected persons the recommendation was less stringent and the position paper concluded that hiv infected persons may "hypothetically, benefit from a second dose or booster dose ".1 Recently, WHO changed the recommendations about a booster dose of YF vaccine, based on the fact that serum neutralizing antibodies against YF are still at detectable levels after 20-35 years and probably lifelong in immunocompetent patients. Unfortunately, data on persistence of Neutralizing antibodies Titers (NT) in immunocompromised patients are missing and only few studies reported data about HIV-infected patients. Additional data are needed. Primary objective: To assess presence / persistence of Neutralizing Titers (NT) of antibodies after YF immunization in HIV-infected patients. Secondary objectives: 1. To identify risk factors for early and late waning of NT after YF immunization 2. To modelize kinetics of NT after YF immunization in different subpopulations of HIV patients, including population of young HIV patients infected vertically 3. To identify risk factors for absence of seroconversion in the year after YF immunization 4. To compare persistence of NT in HIV patients infected vertically or not vertically 5. To quantify seroconversion rate after YF vaccination Methodology / study design This study is a single arm, non randomized, cross-sectional, multicenter study in AIDS Reference Centers from Belgium. The maximum duration of the study for each patient will be 1 visit, consisting of: - the screening and inclusion visit (single visit V1) to check the patient eligibility, sign informed consent, perform the biologic tests necessary for the study and answer the questionnaire - whenever possible, an additional serum / plasma sample coming from serabank / plasmabank will be identified for each patient. This sample must have been taken during the year following YF immunization. - data about patient's HIV history has to be extracted from the HIV database or from patients' file Estimated enrolment 750 patients + 30 patients infected vertically with HIV Primary outcome Number of HIV patients with protective YF NT ≥ 1:10 at different timepoints after YF immunization Secondary outcomes 1. Number of patients with protective YF NT ≥ 1:10 in the year following YF immunization 2. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) for absence of seroconversion in the year following YF immunization 3. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) of early waning (before 10 years) of YF NT 4. Risk factors (demographics and immunovirological parameters, antiretroviral treatment) of late waning (after 10 years) of YF NT Eligibility Inclusion criteria 1. Infection with HIV-1 (vertical transmission or not) 2. Immunization with at least one injection of YF vaccine (Stamaril®,17D strain Rockefeller, Sanofi Pasteur) with proof of vaccine administration 3. Informed consent signed prior to any study procedure Exclusion criteria Inability to give informed consent Substudies - Whenever possible, an additional sera or plasma sample from the year following YF vaccine will be selected and analyzed to assess early seroconversion rate - Whenever possible, an additional sera or plasma sample from the year before YF vaccine will be selected and analyzed to assess seroconversion rate - In CHU Saint-Pierre, an additional cohort of patients infected vertically with HIV will be selected and will participate to the study
This study will evaluate the safety, tolerability and innate immune mechanisms activation following administration of the combination of Pegylated Interferon alpha 2b (peg-IFN-α2b) with two broadly neutralizing antibodies (3BNC117 and 10-1074) in the setting of well-controlled HIV infection with antiretroviral treatment and a monitored analytical treatment interruption. The current proposal builds on previous experience using interferon alpha, 3BNC117 and 10-1074 alone in separate clinical trials that included a closely monitored analytical treatment interruption. The hypothesis is that the joint administration of peg-IFN-α2b with 3BNC117 and 10-1074 will be more effective than either intervention separately in suppressing HIV viremia during 8 weeks of analytical treatment interruption (Step 4) and reducing integrated HIV DNA in blood and tissue when measured during an analytical treatment interruption in patients with well-controlled HIV infection.
Diffusing capacity for carbon monoxide (DLco) abnormalities are common in HIV+ individuals and associated with significant morbidity and mortality. The complexity and the individualized differences in causes of these abnormalities have been challenging to unravel using traditional approaches. In this proposal, the investigators construct a systems' modeling approach to identify novel molecular and clinical pathways contributing to DLco impairment in HIV+ individuals and to determine predictive signatures of DLco decline in order to develop strategies to treat and prevent abnormal lung function in this susceptible population.
It's a prospective observational study to assess frailty and physical function
This study will test the efficacy and cost-effectiveness of an interdependence theory-based couples intervention in Kenya that reaches pregnant women and male partners through home visits by male-female pairs of lay health workers, and includes offer of home-based CHTC services.
