Active clinical trials for "HIV Infections"

This study is aimed to evaluate the effects of yoga intervention versus usual care (control group) for reducing stress among people living with HIV in Indonesia.

This sub-study will assess the pharmacokinetics (PK), safety, tolerability, virologic efficacy and health outcomes of CAB (GSK1265744) and RPV long acting (LA) in HIV-infected adult participants currently enrolled in the Antiretroviral Therapy as Long Acting Suppression every 2 Months (ATLAS2M [A2M]) study (NCT03299049).

This FTIH study aims to evaluate the safety, tolerability and PK of the novel investigational Human immunodeficiency virus (HIV)-1 capsid inhibitor VH4004280 in healthy adults. The study will be conducted in 3 parts: Part 1 will investigate single ascending doses (SAD), Part 2 will investigate multiple ascending doses and drug-drug interaction (MAD/MAD DDI) Part 3 will investigate single dose relative bioavailability (RBA) of a new formulation of VH4004280.

Primary objective: To compare telmisartan therapy + antiretroviral therapy (ART) versus ART alone during acute Human Immunodeficiency Virus (HIV)a infection in reducing systemic immune activation and trafficking of activated and HIV-infected cells to the central nervous system (CNS), and limiting establishment and persistence of the CNS reservoir of HIV. At 48 weeks (during the telmisartan therapy) and 72 weeks (~6 months after cessation of telmisartan augmentation), the investigator expect subjects in the telmisartan group will have reduced levels of blood and CSF immune activation markers, reduced brain inflammation, lower CSF HIV ribonecleic acid (RNA) and improved neuropsychological testing performance. Secondary objective: In subjects who are willing to undergo the optional inguinal lymph node biopsy, the study will determine whether subjects receiving telmisartan plus ART for 48 weeks develop less lymphoid tissue fibrosis than subjects receiving ART alone for 48 weeks. Subject population: Male and female subjects age ≥ 18 years old with acute HIV infection who are identified and enrolled in SEARCH 010/RV254 protocol will be asked to co-enroll in this study. Number of subjects: 21 Duration of follow-up: 72 weeks Study design: 21 acutely HIV-infected subjects will be randomized 2:1 to treatment with telmisartan + ART (n=14) vs. ART alone (n=7) for the first 48 weeks followed by ART alone in both arms to week 72. Blood and CSF, magnetic resonance imaging (MRI), and neuropsychological testing and exam will be collected at baseline, week 48 and week 72. Inguinal lymph node biopsy is an optional procedure that will be offered at baseline and week 48.

The positive patients to the Human Immunodeficiency Virus (HIV) with Highly Active Antiretroviral Therapy (HAART) present multiple alterations in their corporal composition and dyslipidemia, wich increase the cardiovascular risk. The investigators evaluated the efficiency of the combination of fish oil omega 3 fatty acids to different doses with the Therapeutic Lifestyle Changes (TLC) diet of the National Cholesterol Education Program on the profile of lipids and the corporal weight in patients with HIV treated with HAART.

Current HIV treatment guidelines recommend a combination of drugs for the maintenance of antiretroviral therapy (ART). Simplification is considered critical to further scale-up of treatment, to support retention in care and to reduce costs. Dolutegravir is a once daily integrase inhibitor that shows very good tolerability, efficacy, and distinctive resistance profile. The researchers aim at investigating the feasibility of dolutegravir monotherapy in maintenance therapy. Briefly, 10 virologically suppressed patients for at least six months on conventional triple ART of dolutegravir plus two nucleoside reverse transcriptase inhibitors (NRTIs) will be switched to dolutegravir monotherapy for 24 weeks. The primary endpoint is the number of patients completing 24 weeks of dolutegravir monotherapy without experiencing virological failure.

Advances in antiretroviral therapy (ART) have resulted in increased survival of the HIV-infected population; however, this gain in longevity is associated with an increased risk of cardiovascular disease (CVD). Although ART and traditional risk factors contribute to CVD in this population, heightened markers of immune activation, inflammation, and coagulation independently predict morbidity and mortality, suggesting that dysregulation of these systems plays a significant role in the increased risk of CVD. The investigators believe that platelet activation is an important driver in HIV-associated immune activation, inflammation, and coagulation, leading to an increased CVD pathophysiology and risk. Platelets initiate thrombus formation and also play a key role in vascular inflammation by releasing pro-inflammatory mediators and cross-talking with other relevant cell types including leukocytes. Researchers have described platelet hyperreactivity in chronic HIV infection. Importantly, the investigators demonstrated that one week of anti-platelet therapy (aspirin) decreased platelet activation and immune activation, with an improved trend in inflammation and immune parameters. The overall hypothesis is that platelet activation is a major driver of immune activation, inflammation, and thrombosis in ART-treated HIV infected patients. The purpose of the proposed proof-of-concept study is to understand the mechanism(s) by which anti-platelet therapy improves immune and inflammatory parameters in chronic HIV infection. To test this, the immune modulating and anti-inflammatory effects of 24 weeks of the anti-platelet drug aspirin as compared to the anti-platelet drug clopidogrel will be evaluated. Given their different mechanisms of action and inhibitory potency, the investigators can differentiate whether the potential benefits are mediated via inhibition of arachidonic acid (aspirin) or inhibition of ADP (clopidogrel) or by the antithrombotic activity. A secondary goal is to perform multidimensional assays of platelet activity and thrombogenicity alongside immune activation assays and careful assessments of traditional risk factors and medication regimens, to understand which parameters are highly associated with thrombogenicity.

This is a Phase 2, two-step, open-label study of the outcome of analytic treatment interruption (ATI) on patients who started antiretroviral therapy (ART) during Fiebig Stage I of acute HIV infection (AHI), defined as detectable HIV-RNA without detectable p24 antigen or HIV IgM. The primary endpoint will be rate of sustained viral suppression, defined as HIV-1 RNA < 50 cps/ml at 24 weeks after treatment interruption. During ATI subjects will be monitored closely for safety and will have ART re-initiated if they meet predefined clinical, virological, or immunological criteria. In step I, there will be 8 subjects who undergo ATI. An interim analysis for safety will be conducted after 12 weeks. If none of the subjects maintain viral suppression at 12 weeks then no further subjects will be enrolled into the study. If at least 1 out of 8 subjects maintains viral suppression at 12 weeks then an additional 7 subjects will be enrolled in step 2. At ATI all antiretroviral drugs will be discontinued. Subjects will be monitored with clinical exam, immunological (CD4), and virological (HIV-RNA) testing at baseline and then on a fixed schedule for 24 weeks. ART will be re-initiated immediately if subjects meet any pre-defined clinical, immunological or virological safety endpoints during the monitoring period.

The purpose of this study is to determine the lopinavir levels in blood of HIV and TB infected children (3-15kg) when given lopinavir/ritonavir in a 1:1 ratio with rifampicin containing TB regimen and its safety.

Modern antiretroviral therapeutic regimens offer a vast array of choice that permits tailored therapy for HIV patients. While modern regimens have improved the rates of virologic suppression overall and reduced adverse effects of antiretroviral treatment, an important sub-group of HIV infected persons is unable to maintain adherence to their treatment regimens, fail to achieve long term virologic control and remain at risk for HIV related disease progression and transmission of HIV infection. Hypothesis: switching from current cART regimen to a Triumeq based regimen combined with adherence support will improve the rate of HIV suppression in vulnerable populations non-adherent to the their current cART as determined by the achievement of HIV-1 RNA < 50 copies/mL at Week 24 post randomization.
