Active clinical trials for "HIV Infections"

INTRODUCTION: Studies prove that the pharmaceutical care (PC) increases the adherence to the antiretroviral; thus, they increase the undetectable viral load. The viral load diminishes, and the prevalence of undetectable viral load increases, as the levels of adherence to the treatment increase, being in general necessary high adhesion to reach the effectiveness therapeutic. Increasing the adherence levels, it increases the surviving chances and quality of life and diminishes the transmission risks. Studies demonstrate that the self-effectiveness expectation to use the medication correctly is the main predictor of adherence, and that the more complex the therapeutic regimen is, and the perception of side effects, the smaller the adherence is, highlighting the importance of preventing, identifying and solving the problems during the treatment with antiretroviral, problems related to the medication (PRM) through the PC. OBJECTIVES: To evaluate the effectiveness of the PC on the adherence of HIV-patients to the antiretroviral therapy, identify, prevent and solve PRMs during the treatment. METHODOLOGY: One-side randomized clinical trail controlled by non-intervention in parallel. 332 patients randomized are included in the control and intervention groups (PC). Questionnaires will be applied: sociodemographic, adherence to the antiretroviral through self-report, smoke, BECK (depression), CAGE (problems related with alcohol consumption) of self-effectiveness, expectation of results and social support. Each 4 months measure of viral load and CD4 will be carried out. The ones from the PC group will receive a card with information about the medication and all the medicines will be identified by different colors. The follow-up will last one year according to the instructions of DADER program.

Cigarette smoking is a major cause of illness among HIV-infected patients (non-AIDS defining malignancies (especially lung cancer), non-AIDS bacterial infections and cardio-vascular diseases). Approximately 50% of HIV-infected patients are regular tobacco smokers. Tobacco smoking cessation has well known benefits on mortality and morbidity in the general population where tobacco cessation assistance programs are increasingly implemented. However, smoking cessation interventions have never been evaluated among HIV-infected patients. This trial aims at evaluating the efficacy and safety of varenicline for smoking cessation compared with placebo.

The aim of this study is to investigate the responses of the serum amyloid A (SAA) pathway to dietary supplements of glutamine (Gln) and cysteine (Cys) together with methionine (Met)-overloading in HIV+ patients comparatively to healthy controls.

This is a phase I, open-label, controlled drug interaction study to determine the effects of darunavir plus ritonavir on the pharmacokinetics of the hydroxymethylglutaryl coenzyme A (HMG-CoA) reductase inhibitor, rosuvastatin, in HIV-1-seronegative subjects.

Treatment: Immunization with a peptide-mix of 17 Clusters of Differentiation number 8 (CD8) T cell minimal epitopes and 3 Clusters of Differentiation number 4 (CD4) T cell epitopes and a new adjuvant (CAF01). The vaccine should induce cellular immunity against human immuno-deficiency virus type-1 (HIV-1). Target group: Untreated healthy individuals with chronic HIV-1 infection who are not in antiretroviral treatment. Purpose: The primary purpose is to evaluate tolerability and safety of the vaccine. The secondary purpose is to evaluate the clinical effect of the vaccination treatment as measured by induction of new T cell immunity, lowering of HIV-1 ribonucleic acid (RNA) viral load in plasma, and improvement in the patient CD4 lymphocyte blood counts. Design: The experiment is designed as a single-blinded, placebo-controlled phase 1 clinical trial in HIV-1 infected individuals in Denmark. Numbers of individuals: 20 fully evaluable HIV-1-infected patients should enter the study (15 vaccine treated and 5 placebo(saline) treated controls). The hypothesis is that a redirection of cytotoxic T lymphocyte (CTL) immunity to selected relatively immune silent (subdominant) but conserved CTL targets on multiple sites in HIV-1 could provide a better immune control of the virus replication. This could result in lowering of viral load thereby prolonging the time to antiretroviral therapy.

The triple therapy darunavir/r + tenofovir/emtricitabine is likely to become a relevant first-line treatment option in the years to come. The dual combination of boosted darunavir + raltegravir is an innovative treatment option that combines two potent new antiretroviral drugs, one of which belongs to a new drug class (integrase inhibitor). The expected efficacy profile of this combination is promising. Moreover, this combination might have a better tolerance profile and has the advantage of sparing the NRTI class. In the context of tenofovir/emtricitabine currently being a reference backbone in first-line antiretroviral regimens, we hypothesise that, in combination with darunavir/r, raltegravir may be an alternative option if its efficacy is non-inferior to tenofovir/emtricitabine.

The objective of this study is to discover a new approach in which human immunodeficiency virus (HIV) can be eradicated from an infected individual by intensified antiretroviral treatment coupled with immunomodulation. The hypothesis is that eradication is possible only if very potent antiretroviral drugs are delivered in conjunction with an immunomodulatory agent that simultaneously attack the viral reservoirs.

The objective of this double-blinded, multicenter, randomized, active-controlled study is to evaluate the safety and efficacy of Stribild, a single-tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/GS-9350 (cobicistat; COBI)/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF (Atripla) in HIV-1 infected, antiretroviral treatment-naive adult participants. Stribild offers an alternative STR for patients who are not candidates for non-nucleoside reverse transcriptor (NNRTI)-based STRs. Participants will be randomized in a 2:1 ratio to receive Stribild or Atripla. Randomization will be stratified by HIV-1 RNA level (≤ 100,000 copies/mL or > 100,000 copies/mL) at screening. After Week 48, participants will continue to take their blinded study drug and attend visits every 12 weeks until treatment assignments are unblinded (Week 60), at which point all participants will attend an Unblinding Visit and be given the option to participate in an open-label rollover extension (the extension is scheduled to be open until Stribild becomes commercially available, or until Gilead Sciences elects to terminate the study).

The purpose of this study is to determine the safety and efficacy of a VRC DNA/rAd5 vaccine regimen in healthy, circumcised men and male-to-female (MTF) transgender persons who have sex with men. NOTES: As of April 2013, all vaccinations in this study have been stopped. As of June 2017, this study has been closed.

Several studies from HIV-NAT have demonstrated high nevirapine, indinavir, saquinavir and lopinavir/r levels when compared to Caucasian patients. Until now, the pharmacokinetics of atazanavir have not been explored in a Thai population. We postulate that ATV levels, as with other PIs, are higher in Thai people. Therefore, the level of ATV in ATV/RTV 300/100 OD may be higher than the acceptable range and could be associated with ATV related toxicity.
