Filter by:GSK1349572 is an integrase inhibitor that is currently in Phase 2 clinical trials for the treatment of HIV infection. As GSK1349572 development progresses, it may be dosed with non-nucleoside HIV reverse transcriptase inhibitors (NNRTIs) including efavirenz (EFV, Sustiva). Efavirenz is a known inducer of CYP3A4. GSK1349572 is primarily metabolized via UGT1A1, however it also has a CYP component to its metabolism, thus a drug interaction between GSK1349572 and EFV is likely. A previous study showed that another NNRTI, etravirine which is also a known inducer of CYP3A and UGT, reduced GSK1349572 exposure significantly. GSK1349572 is not an inhibitor or inducer of CYP3A and is not expected to have impact on pharmacokinetics (PK) of EFV. This study will investigate the dose proportionality between single doses of 50mg and 100mg of GSK1349572 and will compare steady-state plasma PK, safety and tolerability of GSK1349572 50 mg every 24h (q24h) with and without efavirenz 600 mg q24h. Approximately 12 subjects will receive a single dose of GSK1349572 100 mg (Treatment A) in Period 1 followed by a washout of greater than or equal to 6 days. In Period 2 subjects will receive GSK1349572 50mg q24h for 5 days (Treatment B). Subjects will then be administered GSK1349572 50mg q24h in the morning in combination with EFV 600 mg q24h (Treatment C) in the evening for 14 days in Period 3. There will be no washout between Periods 2 and 3. Safety evaluations and serial PK samples for GSK1349572 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 US, with healthy adult male and female subjects.
This is a single-center, randomized, two part, open-label, crossover study in healthy adult subjects. Part A will evaluate the relative bioavailability of two new tablet formulations compared to the current tablet formulation of GSK1349572 at 50 mg administered as single doses each comprising of two 25 mg tablets. Pharmacokinetic samples from Part A will be analyzed and, if at least one of the new formulations meets appropriate criteria and is selected, Part B will be a single-sequence design conducted to evaluate food effect of the selected new tablet formulation at one dose level. A subset of subjects enrolled in Part A will continue in Part B. Safety evaluations and serial PK samples will be collected during each treatment period. A follow-up visit will occur 7-28 days after the last dose of study drug.
The specific aims of this study are to determine whether HIV-infected patients with significant fat redistribution and ectopic fat accumulation have increased brown adipose tissue using 18F-FDG Positron Emission Tomography techniques. Recent studies suggest down regulation of Dicer, a major component of miRNA has an important role in the differentiation and function of brown and white adipose tissue and may contribute to lipodystrophy. Therefore we will expand on recent research in this area by recruiting HIV-infected men with lipodystrophy. We will perform subcutaneous fat biopsies of the dorsocervical and abdominal fat in a subset of HIV-infected and non-HIV-infected men in order to explore further the question of down regulation of Dicer and its implication on metabolic abnormalities in this population.
The objective of this study is to observe and collect data on the usage, dosing, tolerability, and effectiveness of Kaletra (lopinavir/ritonavir) tablets in human immunodeficiency virus (HIV)-infected patients. In some patients, the study is to show the impact on tolerability of changing therapy to Kaletra tablets from other regimens.
To evaluate the safety and efficacy of Stribild®, a single tablet regimen (STR) containing fixed doses of elvitegravir (EVG)/cobicistat (COBI [GS-9350])/emtricitabine (FTC)/tenofovir disoproxil fumarate (TDF) versus efavirenz (EFV)/FTC/TDF (Atripla®) in HIV-1 infected, antiretroviral treatment-naive adults. Stribild offers an alternative STR for patients who are not candidates for non-nucleoside reverse transcriptor-based STRs.
The purpose of this study is to evaluate the safety and immune response of an adenovirus-based HIV-1 vaccine regimen that includes two vaccines given at different time points in HIV-uninfected adults.
The purpose of this study is to evaluate how Vitamin D affects endothelial function, inflammation, lipids, insulin resistance, vitamin D levels, and PTH.
Optimal vitamin D (vit D) concentration and metabolism are essential for normal immune function, growth, muscle, bone, and inflammatory status in children, adolescents and adults with HIV/AIDS. The impact of vit D supplementation will be evaluated for safety and efficacy using clinically important outcomes, and this will overcome the critical barrier for use of vit D supplementation in research and clinical care. Inexpensive and easy to administer, vit D supplementation may prove to be an effective and feasible treatment for symptoms and prevention of side effects for people of all ages living with HIV/AIDS in the US and around the world.
This trial is designed to assess the swallowability of uncoated and film-coated 200 mg etravirine tablets in HIV-1 infected patients. In addition, comparisons between a single 200 mg tablet versus two 100 mg formulations will be made. The outcome of the trial will aid in making decisions about the future commercial 200 mg formulation.
Under funding from the National Institute on Drug Abuse, the UCLA Integrated Substance Abuse Programs (ISAP), in collaboration with Walden House and the California Department of Corrections and Rehabilitation, is conducting a five-year study that will involve a randomized test of the use of incentives with parolees in a community-based residential substance abuse treatment program to increase treatment admission and treatment retention, and thereby increase the likelihood of improved outcomes. Study participants will be recruited from clients in a prison-based treatment program who have a referral to the Walden House community program. The Admission Phase of the study assesses the effect of an incentive (voucher) on enrolling in the Walden House program. The Attendance Phase assesses the effect of incentives on treatment attendance and on post-treatment drug use, crime, and psychosocial behaviors, including HIV risk behaviors. In addition, an incentive protocol will test whether an incentive will encourage participation in HIV testing and counseling. The intervention will last for six months. Hypothesis 1. The use of incentives will significantly increase subject enrollment in community treatment. Hypothesis 2. The use of incentives will significantly increase subject retention in community treatment. Huypothesis 3. The use of incentives will significantly increase subject participation in HIV testing and counseling. Study participants will be interviewed at baseline and at 12 months following the intervention. Treatment and criminal justice data will be obtained. Data on acceptability, satisfaction, and sustainability will be collected from focus groups with staff and clients.
