Active clinical trials for "HIV Infections"

This trial addresses the question of the viral load (VL) threshold for switching from first-line to second-line antiretroviral therapy (ART). The WHO currently sets the threshold at 1000 copies/mL. However, the optimal threshold for defining virological failure and the need to switch ART regimen has not been determined. In fact, people with VL levels of less than 1000 copies/mL, however, not fully suppressed, are at increased risk for drug resistance mutations (DRM) and subsequent virological failure. In resource-limited settings where VL monitoring is not as frequent as in high-income countries, this could have serious implications and patients may continue on a failing regimen for a long period. Our research consortium will conduct a multicenter, parallel-group, open-label, randomized clinical trial in a resource-limited setting to assess whether a threshold of 100 copies/mL compared to the WHO-defined threshold of 1000 copies/mL for switching to second-line ART among unsuppressed HIV-positive patients on first-line ART will lead to better outcomes.

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.

This is a Phase I, single-center, open-label, fixed-sequence, 2-period crossover study in healthy adults to evaluate the effect of oral rifabutin (RBT) 300 milligram (mg) on the pharmacokinetics of oral cabotegravir (CAB) 30 milligram ( mg). This study will evaluate the drug-drug interaction (DDI) potential between CAB and RBT to inform dosing strategies for tuberculosis in subjects receiving CAB for human immunodeficiency virus (HIV) treatment or prevention. In Treatment Period 1 (Treatment A) participants will receive CAB 30 mg once daily for 14 days, followed by Treatment Period 2 (Treatment B) where participants will receive RBT 300 mg once daily with CAB 30 mg once daily for 14 days. The total study duration will be approximately for 10 weeks. Approximately 15 healthy subjects will be enrolled to ensure that 12 subjects complete dosing and critical assessments.

This study will evaluate the frequency of ovulation and cervical mucus quality of HIV-infected women on efavirenz (EFV)-based antiretroviral therapy (ART) using either a single etonogestrel (ENG) implant or two ENG implants for at least one year.

This is an open label, randomized Phase II study to determine whether Mycophenolate mofetil (MMF) given over 22 months meaningfully decreases the size of participants' HIV reservoir. In addition to primary safety endpoints, the following hypotheses regarding drug efficacy will be tested: MMF will be well tolerated and will not decrease adherence to or antiviral efficacy of ART. Peripheral CD4+ T-cell counts and percentages will not meaningfully decrease during treatment with MMF and ART. There will be no excess risk of opportunistic infections in MMF-treated study participants. MMF therapy will lead to a progressive decrease in reservoir size over 22 months of treatment. MMF therapy will lead to a continual shift in HIV reservoir composition from primarily effector memory CD4+ T cells (TEM) and central memory CD4+ T cells (TCM), to primarily stem cell like memory (TSCM) and naïve (TN) CD4+ T cells. MMF will eliminate detectable measures of the HIV reservoir, including by cell-associated DNA/mRNA and quantitative viral outgrowth. MMF will not decrease the humoral immune response to routine annual influenza vaccination.

Phase I, randomized, double blind, placebo-controlled, dose-finding trial. The trial´s goal is to evaluate two different doses of Bryostatin on HIV-1 latency and reservoir in HIV-1 infected patients receiving antiretroviral treatment.

Primary: Sequentially determine the effects of three dose combinations of tipranavir (TPV) / ritonavir (RTV) (administered b.i.d.), TPV 1250 mg/RTV 100 mg vs. TPV 750 mg/RTV 100 mg vs. TPV 250 mg/RTV 200 mg on the steady-state pharmacokinetics of zidovudine, lamivudine, stavudine, didanosine, abacavir, nevirapine and efavirenz at approved doses. The three treatment groups will be enrolled sequentially starting with the highest tipranavir dosage group first and ending with the lowest tipranavir dosage group. Secondary: A) To assess the effects of zidovudine, lamivudine, stavudine, didanosine, abacavir, nevirapine, and efavirenz on the pharmacokinetics of tipranavir/ritonavir compared to historical controls. B) To assess the safety of three tipranavir/ritonavir combinations when used in combination with protocol defined antiretrovirals.

The primary objective of this study is to evaluate the efficacy of a regimen containing elvitegravir/cobicistat/emtricitabine/tenofovir disoproxil fumarate (E/C/F/TDF) versus ritonavir (RTV)-boosted atazanavir (ATV/r) plus emtricitabine/tenofovir disoproxil fumarate (FTC/TDF) in HIV-1 infected, antiretroviral treatment-naive adult women.

The purpose of this trial is to assess the antiviral activity and safety of a dolutegravir (DTG) containing regimen in HIV-1 infected, antiretroviral therapy (ART)-experienced adults with current or historical failure on an integrase inhibitor (INI) containing regimen. The study will assess DTG 50mg twice daily administered initially with the current failing ART regimen but then with an optimised background ART regimen (OBR) after Day 7. The first analyses will be conducted after the last subject enrolled has completed 24 weeks. Subjects may remain on study after Week 24.

This research work is important for the cure/control of HIV infection. The study is intended to confirm the efficacy of "Kallunk Oxide (Immunotherapy)" molecules in the Treatment of HIV infection. The study will investigate the T- Lymphocytes (immune) response to HIV in order to boost the body's natural immune ability against infection. The basic study is directly inhibit a protein's increased functions, not only in the CD4+T cell but also CD3+ and CD8+ T cells and the CD45+. cells. The 'Yogaprabhava', the drug's effectiveness, and progressive immunity with diet and lifestyle can be more easily studied.
