Filter by:This study will evaluate the effect of an American Indian/Alaska Native (AI/AN) adaptation of the It's Your Game…Keep It Real (IYG) intervention, relative to a comparison condition on sexual behavior outcomes and psychosocial variables for middle school aged youth (12 - 14 years old). The original IYG program was designed for students in Houston middle schools to help students delay sexual initiation and if sexually active, use condoms and contraception. The present study will adapt the existing IYG program for an AI/AN youth cohort; the original IYG curriculum will be transferred into a web-based format and modified to incorporate additional culturally-relevant components. The primary hypothesis to be tested is: (1) students who receive the web-based curriculum will delay sexual activity relative to those who receive standard care. The major dependent variable is the proportion of students initiating sexual activity. Secondary hypotheses will examine the effect of the web-based curriculum on specific types of sex and psychosocial variables related to sexual risk-taking behavior. This project will also examine the effect of the intervention on the proportion of students who are sexually active, number of times students engage in unprotected sexual intercourse, and students' number of sexual partners.
Dolutegravir (DTG) is an HIV drug in the integrase inhibitor drug class. This study evaluated the pharmacokinetics (PK), safety, tolerability of and immune response to DTG when used concurrently with optimized background therapy (OBT) in HIV-1 infected infants, children, and adolescents.
The investigators' in vitro data suggest that Neurokinin-1 receptor antagonists like aprepitant will decrease the expression of CCR5, an essential co-receptor in the life cycle of HIV, in the surface of macrophages and lymphocytes to levels at least similar to those observed in patients heterozygous for the CCR5 32 mutation. Together with a direct potential antiviral effect this could alter disease progression in patients with HIV infection. The investigators' hypothesis is that aprepitant is safe, tolerable and has antiviral activity in HIV infected individuals. This is randomized, placebo controlled, double blind study to determine the safety and antiviral activity of aprepitant by comparing the change in HIV RNA viral load after 2 weeks of aprepitant monotherapy. 18 HIV infected males and females ≥ 18 years old who have early infection with CD4 cell counts ≥ 350 cells/mm3. Subjects will be randomized 1:1 to receive 375 mg of aprepitant (Emend®) or placebo.
There has been reports that low dose prednisolone stabilizes CD4-counts in HIV infected individuals. However, until now, there are no prospective randomized studies on the use of corticosteroids in latent HIV disease. Furthermore, low dose prednisolone (5 mg/d) is not sufficient tested for the risks and benefit for HIV patients especially for those living in poor settings with a higher risk of infections. This study will assess the benefit and the safety profile for low dose prednisolone therapy for patients in a region with limited resources and high prevalence of infections.
This prospective observational study will evaluate predictors of response to Invirase (saquinavir) treatment in treatment-naïve patients with HIV infection. Data will be collected during 48 weeks of treatment.
Background: - Antiretroviral therapy (ART) has been able to improve the lifespan of individuals infected with human immunodeficiency virus type 1 (HIV-1), but ART requires continuous treatment that has substantial consequences on quality of life. Recent research is attempting to determine whether this persistent infection stems from a low-level infection where new cells are continually infected with HIV, or from cells that live for a long time after infection. ART is very active against the virus in new cells, but has no effect on long-lived cells that are already infected with HIV-1 at the start of ART. As a result, new strategies may be necessary to reduce or eradicate these 'reservoir' cells. - Interferon is a natural substance made by the body to combat virus infections, and can be made as an injectable drug known as PEGINTRON. Researchers are interested in determining whether PEGINTRON therapy will also reduce the residual low levels of HIV in patients who are already taking ART. Objectives: - To evaluate the effectiveness of PEGINTRON injections on HIV levels in participants currently undergoing antiretroviral therapy. Eligibility: - Individuals at least 18 years of age who have been diagnosed with HIV, are currently undergoing antiretroviral therapy, and have maintained HIV virus blood counts that are not detectable by current commercial tests for at least 12 months before the start of the study. Design: - This study will involve separate screening and treatment processes. - Participants will be screened with a physical examination and medical history, including blood and urine samples. The screening analysis to determine study eligibility will take several weeks. Participants will have apheresis to provide sufficient numbers of blood cells for evaluation by the study researchers. - Eligible participants will begin a 4-week course of PEGINTRON injections using the standard dose of PEGINTRON that is approved for treatment of chronic hepatitis C. Participants will have weekly injections and have frequent blood tests to measure HIV virus levels. - Participants who experience problems in maintaining safe numbers of white blood cells during the study may receive injections of filgrastim to increase their white blood cell count. - After the 4 weeks of treatment, participants will return for additional blood tests on study days 28, 35, 42, 49, 56, and 84, and Weeks 16, 24, 36, and 48 (i.e., through the end of 1 year after the start of the study).
The main objective of this clinical trial in randomizing HIV infected patients under good HIV control with tenofovir (TDF), emtricitabine (or lamivudine) plus lopinavir/ritonavir (LPV/r) into switching the regimen to raltegravir (RAL) with darunavir/ritonavir (DRV/r) or continuing the ongoing regimen to compare these two groups' estimated glomerular filtration rate (eGFR) is to investigate whether anti-HIV treatment that does not contain TDF or other reverse-transcriptase inhibitors (NTRI sparing regimen) can be protective of patients' renal functions and has the same virological efficacy in comparison with a standard treatment with TDF, or not.
Raltegravir is the first integrase inhibitor used in humans. It has been shown to be highly efficacious and well tolerated in phase III clinical trials in multidrug experienced human immunodeficiency virus(HIV)-infected patients, as well as initial therapy in untreated patients. Pharmacokinetic studies in healthy adult subjects indicate that the major mechanism of clearance of the drug is glucuronidation mediated by UGT1A1, with a minor contribution of renal excretion of unchanged parent compound. Unlike CYP-based metabolism, glucuronidation is generally found to be relatively unaffected by hepatic disease. A single dose pharmacokinetic study of raltegravir in patients with mild to moderate hepatic insufficiency (Steigbigel et al. 2008) found no clinically important effect on the drug pharmacokinetic profile, with no dosage adjustment being necessary. The liver safety and tolerability of boosted atazanavir (ATV/r) has been evaluated in human immunodeficiency virus and hepatitis C virus (HIV/HCV) coinfected patients with advanced liver disease (decompensated cirrhosis) (Hermida JM et al. 4th IAS: Sidney, 2007). Similar to Raltegravir, ATV is also mainly metabolized by conjugation through UGT1A1. There is an urgent need for potent and efficacious ARV drugs with a clean safety liver profile even in patients with severe liver disease. The investigators hypothesized that pharmacokinetics will not be altered in HIV/HCV patients with advanced (Child-Pugh grade C) cirrhosis or in those with no histologic liver damage.
The purpose of this study is to investigate the effect of steady-state concentrations of raltegravir (administered as 400 mg, twice daily) on the steady-state pharmacokinetics of TMC278 (25 mg, once daily), and vice versa. Steady state is a term that means that the drug has been given long enough so that the plasma levels will remain at about the same level with each subsequent dose. TMC278 is being investigated for the treatment of human immunodeficiency virus (HIV) infection. Raltegravir is a commercially available antiretroviral drug for treatment of HIV infection. Pharmacokinetics (PK) means how the drug is absorbed into the bloodstream, distributed in the body and eliminated from the body.
The objective of this study is to evaluate the effect of boceprevir (steady state) on the pharmacokinetics of a single dose of raltegravir. The effect on the boceprevir pharmacokinetics of a single dose raltegravir will also be evaluated (compared to historical controls). Furthermore, the safety profile of the combination is studied.
