Active clinical trials for "HIV Infections"

Certain patients who are participating in NIH protocols involving interleukin-2 (IL-2) therapy for HIV disease may be requested to have the following changes or additions to their study protocol: 3-day subcutaneous (sc) IL-2 administration: Patients currently receiving IL-2 intravenously (injections through a vein) may switch to subcutaneous administration (injections under the skin). Injections are given twice a day for 3 to 5 days (one treatment cycle), with cycles repeated no more often than every 8 weeks. Home treatment of sc IL-2: Home administration of IL-2 injections involves less frequent data and safety monitoring and no medical evaluations at the Clinical Center except at the beginning of each cycle. Participants will receive IL-2 cycles on the same schedule they followed in their original protocol. They will be seen at the Clinical Center at regularly scheduled follow-up visits between cycles and for a medical evaluation and blood drawing before the start of each cycle to determine the safety of administering the next cycle. During the home cycle, the patient's case manager or other team member will place monitoring telephone calls on days 2 and 4 of the cycle and again a week later. The timing and number of these calls may change depending on the findings of ongoing assessments of their usefulness. Patients will be required to notify the study team promptly of complications or other problems that develop with therapy. Stored specimens and HLA testing: Stored blood and tissue samples from patients will be used for future research on HIV, AIDS and related medical conditions, and the immune system. The samples may be labeled with no identifying information, with identifying information, such as the patient's name, or with a code that only the study team can link to the patient. Some of the blood drawn may be used for HLA typing, a genetic test of markers of the immune system. Usually used to match bone marrow or organ transplants, HLA type might also be used to try to identify factors associated with the progression of HIV disease or related conditions. Determining HLA type is also necessary to be able to perform certain research studies. Tonsillar biopsy: Examination of tonsil tissue may provide information on the effects of IL-2 on the immune system and the expression of HIV. Patients in the randomized IL-2 study (93-CC-0113) may have tonsillar biopsies done up to three times-soon after enrollment, after month 4, and after month 12. Patients in the open IL-2 study (91-CC-0143) would have procedures no more often than every 3 months, with the following exception: patients in either study who are willing to have repeat biopsies performed during IL-2 therapy will have the procedure done up to three times during a round of IL-2: before Il-2 therapy, day 2-3 or IL-2 therapy, and day 4-6 of IL-2 therapy, if the sequential biopsies can be safely performed. The area to be biopsied will be numbed with a local anesthetic and 1 to 2 small pieces of tissue will be biopsied. Skin biopsy: Examination of skin tissue may help to explain how IL-2 causes changes in the skin. Biopsies will be obtained from areas of the skin that have been affected by IL-2 as well as from normal, unaffected areas for comparison. Patients with Kaposi sarcoma will also have biopsies of normal skin to allow comparison with IL-2-induced changes in the Kaposi sarcoma lesions. The areas to be biopsied will be numbed with local anesthetic and a 2-mm (1/10th-inch) piece of skin will be biopsied from each site.

This study is designed to test the hypothesis that, compared to oral PrEP, use of CAB-LA in underserved populations in a real-world setting supported by a digital health companion program will be associated with greater medication adherence, persistence, retention-in-care, and improved PROs. Patients in the study will receive current standard care for HIV prevention and be offered enrollment in the digital health companion program. Goal of the study is to evaluate medication adherence and persistence in patients receiving CAB-LA vs oral PrEP and who engage with a digital health companion program.

This is a cohort, non-health product, non-interventional biomedical research, multi-centric, to determine the seroprevalence of mpox infection in the population of people living with HIV and in PrEP users in Ile-de-France and in the province.

Egypt is a HIV low prevalence country but between 2010 and 2019 newly infected cases have more than quadrupled, and the rise continues at an alarming pace. Maintaining over 95% adherence level among the PLHIV in developing countries is a crucial issue to maintain viral suppression, to minimize HIV related morbidity and mortality. The present study aims to identify the level of adherence and the factors influencing adherence to ART in Assiut Governorate. To the best of our knowledge, no previous studies on adherence to antiretroviral therapy and its associated factors in HIV infected individuals were done in Egypt.

The strategy to support virological suppression on second-line antiretroviral treatment (ART) includes the provision of ART that has a low pill burden, good tolerability, low toxicity, is easily monitored, has a high barrier to resistance, and that is low cost. The fixed-dose combination of tenofovir-lamivudine-dolutegravir offers significant advantage as a potential second-line regimen compared to the World Health Organization standard of care second-line regimen of zidovudine-lamivudine-dolutegravir, in terms of cost, tolerability and monitoring requirements. The ARTIST study is a phase 2, randomised, double-blind, placebo-controlled trial aiming to determine the proportion of patients achieving virological suppression when recycling the tenofovir-emtricitabine/lamivudine backbone with dolutegravir (tenofovir-lamivudine-dolutegravir fixed-dose combination) as a second-line with and without a lead-in supplementary dose of dolutegravir, in patients failing a tenofovir-emtricitabine/lamivudine-efavirenz first-line regimen. There is evidence to suggest that even in the presence of resistance mutations to tenofovir and lamivudine (K65R or M184V/I), using this backbone with dolutegravir will provide an effective second-line regimen in patients who have failed a first-line regimen of tenofovir-emtricitabine/lamivudine-efavirenz. The strategy of giving a lead-in supplementary dose of dolutegravir is in view of the inducing effect of efavirenz on dolutegravir metabolism and transport that persists for 2 weeks after efavirenz is stopped; the inducing effect decreases with time after efavirenz is stopped. Given that these patients will have elevated viral loads, a high baseline risk of nucleoside reverse transcriptase inhibitor (NRTI) resistance and efavirenz resistance, and the inducing effect of efavirenz on dolutegravir metabolism and transport that persists for 2 weeks, this study will comprise two stages. The first stage will evaluate virological suppression in 62 participants initiated on the fixed-dose combination of tenofovir-lamivudine-dolutegravir with a lead-in supplementary dose of dolutegravir for the first 14 days. The study will progress to the second stage if this strategy proves effective, and 130 participants will then be randomised to receive the fixed-dose combination of tenofovir-lamivudine-dolutegravir with and without this lead-in dose. The primary endpoint is virological suppression (viral load <50 copies/mL) at 24 weeks. A pharmacokinetic sub-study will be conducted on 12 participants in stage 1 and 24 participants in stage 2, to assess the trough concentrations of dolutegravir and off-treatment concentrations of efavirenz at day 3, 7, 14, and 28. This is to evaluate the need for the lead-in supplementary dose of dolutegravir.

Patients eligible for the study will be selected on Fridays during the HIV consultation at the Infectious Diseases Department. Patients that meet the inclusion and exclusion criteria, will be randomized and assigned in two groups 1:1. A group will start intervention with FMT (fecal matter transplant) through frozen capsules and after seven days, antiretroviral therapy (ART) will be started. Patients in the other group will be given placebo capsules and after seven days ART will be started. The frozen capsules of FMT will be ingested orally with a frequency of 15 capsules every 12 hours for 4 doses 7 days prior ART start and on weeks 0, 4, 8 and 12 after ART start. Subsequently, blood samples will be taken to monitor the immune status with CD4 T lymphocytes and HIV viral load during week 0, 4, 8, 12 and 24 after ART start. Throughout the study period, subjects can carry out a free diet, moderate alcohol intake, perform their daily activities and abstain from any of the elimination criteria. Medical consultations will be made on days -7 to ART start, day 1, 30, 60, 90 and 120 after ART start, where clinical examination and elimination criteria will be evaluated.

This study will compare the pharmacokinetics of the component drugs in JULUCA, and HIV combination treatment pill, in HIV-negative patients who require hemodialysis with those with normal renal function.

Drug therapy for persons living with human immunodeficiency virus (HIV) or acquired immunodeficiency syndrome (AIDS) co-infected with latent tuberculosis infection (LTBI) is complex. Anti-tuberculosis drugs used to treat LTBI often induce drug metabolizing enzymes that share the same metabolic pathway as antiretroviral drugs used for those living with HIV/AIDS. This study evaluates the drug-drug interaction (DDI) potential of an antiretroviral drug when co-administered with a common anti-tuberculosis regimen of drugs.

Early initiation of antiretroviral therapy (ART) reduces morbidity and mortality for individuals infected with HIV. Suppressing viral replication with ART also reduces the potential for transmission of HIV. Hence, ART is recommended for all persons with HIV viremia regardless of cluster of differentiation 4 (CD4) count. This is an open-label single arm which will evaluate the feasibility, efficacy and safety using a fixed dose combination (FDC) of Dolutegravir (DTG) plus Lamivudine (3TC) as a first line regimen of a rapid Test and Treat model of care over 48 weeks. Participants with new and confirmed diagnosed HIV-1 who are willing to start study treatment immediately following diagnosis will receive 50 milligram (mg) DTG + 300 (mg) 3TC FDC as first line therapy without waiting for screening laboratory results, at the Screening/Day 1 Visit. The total duration for the study will be 52 weeks and 4 weeks of follow up period if required. This study will be conducted in United States (US) with approximately 120 participants.

This study is designed to evaluate safety, tolerability, and pharmacokinetics of a single 1200-mg dose of raltegravir (MK-0518, ISENTRESS®) in healthy Japanese male participants.
