Active clinical trials for "HIV Infections"

Dyslipidaemia, characterized by raised triglyceride and low-density lipoprotein (LDL) cholesterol and reduced high-density lipoprotein (HDL) cholesterol levels, is common in HIV-infected individuals, and has been associated with HIV infection itself and antiretroviral therapy (ART). These abnormalities are well-established markers of cardiovascular (CVD) risk in the general population. Studies have suggested an increased risk of CVD associated with ART exposure over and above that conveyed by traditional cardiovascular risk factors. In HIV population to reduce lipid parameters, the most usual clinical strategy remains to add a statin treatment. Recent studies suggested ART switch can represent an interesting alternative to statins to reduce lipid plasma levels. The purpose of this study is to evaluate the frequency with which the replacement of LPV/r (lopinavir/ritonavir), ATZ/r (atazanavir/ritonavir), DRV/r (darunavir/ritonavir) or EFV (efavirenz) by ETR (Etravirin) in dyslipidemic patients with suppressed viremia would obviate the necessity to administer statins. A prospective, phase III study in which the statin treatment of dyslipidemic HIV patients on antiretroviral drugs (ARVs) will be interrupted during 4 weeks is proposed. At week 4, patients qualifying for a lipid lowering drug (calculated LDL-C≥ 3mmol/L) will replace EFV, LPV/r, DRV/r or ATZ/r by ETR. The proportion of patients not qualifying anymore for a statin treatment at 12 weeks (i.e. after 8 weeks of ETR treatment) will be determined. Additionally, the lipid level changes will be assessed at 12 weeks. Inflammatory markers will be measured at baseline, at drug switch and at the end of the study Study drug will be provided by the drug manufacturer (Janssen-Cilag, AG). Compliance for study drug will be done at week-4 and week-12, Returned study medication will be counted and the amount notified on the Case Report Form (CRF).

The purpose of this study is to evaluate the virological efficacy of maintenance therapy with atazanavir with ritonavir combined with lamivudine in treatment experienced HIV positive patients with full and stable virological suppression.

Study to determine the effects of nevirapine treatment on the pharmacokinetics of ethinyl estradiol (EE)/norethindrone (NET).

The trial will evaluate the pharmacokinetics, safety, efficacy and acceptability of twice- and once-daily dosing of lopinavir/ritonavir tablets (Kaletra) dosed by weight in HIV-1 infected children who are currently taking lopinavir/ritonavir as part of their combination antiretroviral therapy and who are currently achieving virological suppression (<50 copies/ml). Specifically: To confirm weight-based dosing recommendations by evaluating the pharmacokinetics of twice-daily lopinavir/ritonavir half strength formulation tablets dosed on body weight and comparing to historical adult and paediatric data of pharmacokinetics of lopinavir/ritonavir soft gel capsules and oral solution respectively (1, 2). To compare the pharmacokinetics of twice-daily lopinavir/ritonavir tablets with once-daily dosing in the same children. To evaluate whether once-daily dosing of lopinavir/ritonavir is comparable to twice-daily dosing in terms of virological suppression at 48 weeks. Adherence and acceptability will also be compared.

The Study will help to compare the Quality of Life for those HIV patients that are on monotherapy with LPV/r Vs. triple therapy with a boosted protease inhibitor

The current study is designed to confirm the mechanism behind the increase in serum creatinine observed during GSK1349572 therapy; specifically, the study will determine whether GSK1349572 has any effect on glomerular filtration rate (GFR) or effective renal plasma flow. Absent such effects, one may conclude that the small increases in serum creatinine observed are due to the inhibition of the tubular secretion of creatinine via organic cation transporter 2 (OCT2) consistent with in vitro data. .

Hypothesis: the Telaprevir(TVR) plasma levels (750 mg q8h or 1125 mg/12h )will not be affected when co-administered with un-boosted Atazanavir (ATV) 200 mg q12h plus two analogues (NRTIs) in HCV/HIV-co-infected patients.

24 healthy male and female volunteers who are at low risk of HIV infection and entered into the RISVAC02 study and were randomly allocated to receive 3 intramuscular injections of MVA-B at weeks 0, 4 and 16 will receive a boosting dose 4 years thereafter. Participants will attend one of two clinical centres on at least 5 occasions over 16 weeks. These visits will comprise: Screening Trial entry and boosting immunisation Early follow-up after immunisation Follow-up x 2 including the final visit Participants will have blood and urine collected, and receive 1 immunisation. They will be counselled prior to and following a HIV test, and given health education on prevention of sexually transmitted infections including HIV. T The two centres which participate are: Hospital Clinic, Barcelona and Hospital Gregorio Marañón, Madrid The primary objective is to explore the safety and immunogenicity of MVA-B.

Human immune virus (HIV) infected subjects may take mineral supplements in combination with their antiretroviral medications. Calcium and Iron supplementations are commonly used and both of these have the potential to interact with Dolutegravir (DTG), this study will evaluate the potential of calcium and iron supplements to decrease DTG exposure. It will also evaluate two possible strategies for combined use; if an interaction is observed. The first strategy is a two hour separation. The second strategy involves the administration of DTG and the supplement with a meal since the presence of food modestly increases DTG exposure, and because mineral supplements can be administered with food. This is an open label, randomized, two cohort, four-period cross-over study in healthy volunteers. One cohort will examine the effects of calcium carbonate and the other cohort will examine the effects of ferrous fumarate on the pharmacokinetic (PK) of DTG. Approximately 12 subjects will be enrolled into each of the two cohorts and receive each of four treatments in a randomized fashion: 1) A single dose of DTG 50 milligram (mg) administered under fasted conditions ; 2) A single dose of DTG 50 mg co-administered with a single dose of calcium carbonate or ferrous fumarate under fasted conditions ; 3) A single dose of DTG 50 mg co-administered with a single dose of calcium carbonate or ferrous fumarate with a moderate-fat meal; 4) A single dose of DTG 50 mg administered under fasted conditions 2 hours prior to administration of a single dose of calcium carbonate or ferrous fumarate. There will be a washout period of at least 7 days between treatments. Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 7-14 days after the last dose of study drug. This study will be conducted at one center in the United States, with healthy adult male and female subjects.

This is a triple cohort, open-label pilot study of the safety and antiviral activity of a single infusion of autologous CD4+ T cells genetically modified at the CCR5 gene by Zinc Finger Nucleases SB-728mR (ZFN Modified CD4+ T Cells) using electroporated mRNA with or without the prior administration of two different doses of cyclophosphamide.
