Filter by:This study is to evaluate the safety and tolerability of cobicistat-boosted darunavir plus two fully active nucleoside analogue reverse transcriptase inhibitors in HIV 1 infected, antiretroviral treatment-naive and treatment-experienced adults with no darunavir (DRV) resistance-associated mutations. After the Week 48 Visit, participants will be given the option to participate in an extension period to receive cobicistat and attend visits every 12 weeks until it becomes commercially available, or until Gilead Sciences elects to terminate development of cobicistat.
This project aims to assess different antiretroviral treatment strategies, optimally controlled and conventional, in relation to drug resistance and virological treatment failure. A Randomised Controlled trial (RCT) where Vietnamese HIV+ patients with CD4+ T-cells <200/ul are randomized into either enhanced treatment support (ETS) through peer supporters or The National AIDS Control Program recommended self supervised treatment (SST). The treatment strategies will be assessed and compared in relation to treatment adherence and drug resistance development with virological treatment failure as primary endpoint. The results from this project will lead to an increased knowledge in relation the impact of treatment support on adherence, virological suppression and resistance development and have an impact on HIV treatment policies in low income settings globally.
Early accurate diagnosis is one of the first crucial steps in care for infants born to HIV-infected mothers. Early initiation of antiretroviral therapy (ART) relies upon early diagnosis and results in significant reductions in infant morbidity and mortality. There is little information on evidence-based interventions that specifically target improved attendance of postpartum clinic visits and subsequent infant HIV testing in the context of prevention of mother-to-child transmission of HIV (PMTCT) programs. The investigators propose a randomized controlled trial to examine the effect of text messages sent to women enrolled in PMTCT programs on adherence to postpartum clinic visits and uptake of early infant diagnosis by DNA polymerase chain reaction (PCR). This study seeks to test the hypotheses that (a) text messages sent to women enrolled in PMTCT will improve their attendance at the postnatal clinic within the first 6-8 weeks after childbirth; and (b) text messages sent to women enrolled in PMTCT programs will increase uptake of DNA PCR HIV testing at 6-8 weeks among infants exposed to HIV. This study will evaluate a novel strategy to improve adherence to postnatal clinic visits and increase the uptake of infant HIV testing. If proven superior to standard care, the proposed intervention can be easily scaled-up and integrated into existing healthcare systems in resource-limited settings. Findings from this study will provide randomized trial evidence to inform HIV prevention program planners and implementers. This study will also provide further information on the feasibility of using mobile phone-based technology for public health interventions in resource-limited settings.
Dolutegravir (DTG, GSK1349572 is an integrase inhibitor that is currently in Phase 3 clinical development for the treatment of human immunodeficiency virus (HIV) infection. DTG is primarily metabolized by UDP-glucuronosyltransferase (UGT1A1) with cytochrome P450 (CYP)3A4 pathway as a minor route. Corticosteroids have demonstrated induction effects on UGTs and CYP3A4. Corticosteroids are often used in HIV-infected subjects and have the potential to reduce DTG exposure due to enzyme induction when co-administered. The primary objective of this study is to determine whether concomitant prednisone administration can affect the pharmacokinetics (PK) of DTG. The study is a two part, two period, open label study. Part 1 will evaluate the effect of a high prednisone dose on DTG PK with the potential for an additional Part 2 depending on the results from Part 1. In Part 1, approximately 12 healthy subjects will receive DTG 50mg q24h for 5 days in Period 1. Subjects will then be administered DTG 50mg q24h in combination with prednisone 60mg for 5 days followed by a 5 day taper (total duration of 10 days) in Period 2. PK data of DTG will be obtained from Part 1 and used to inform decision making on the need for Part 2. If DTG exposure is reduced by more than 50% in Part 1, Part 2 will be carried out where a second cohort of subjects will receive DTG 50mg q24h DTG for 5 days in Period 1 followed by DTG 50mg q24h in combination with prednisone 20mg for 5 days followed by a 5 day taper (total duration of 10 days) in Period 2. Safety evaluations and serial PK samples for DTG will be collected during each treatment period. A follow-up visit will occur 7-14 days after the last dose of study drug. All doses of study drugs will be taken following a moderate fat meal. This study will be conducted at one center in the United States, with healthy adult male and female subjects.
Both antiretroviral therapy (ART) and prevention of opportunistic infections (OIs) have been associated with significantly decreased mortality in HIV-infected individuals. Trimethoprim-sulfamethoxazole (TMP/SMZ), also known as bactrim, is a common antibiotic and used as prophylaxis for OIs. For countries with high prevalence of HIV and limited health infrastructure, the WHO endorses universal TMP/SMZ for all HIV-infected individuals. Notably, these guidelines were created prior to the scale-up of ARTs. Following ART and subsequent immune recovery, TMP/SMZ may no longer be required. In the US and Europe, for example, TMP/SMZ is discontinued after patients show evidence of immune recovery. Therefore, we propose a prospective randomized trial among HIV infected individuals on ART with evidence of immune recovery (ART for > 18mo and CD4 >350 cells/mm3) to determine whether continued TMP/SMZ prophylaxis confers benefits in decreasing morbidity (malaria, pneumonia, diarrhea), mortality, CD4 count maintenance, ART treatment failure and malaria immune responses.
The purpose of this study is to learn more about the safety and tolerability of etravirine. Etravirine is a type of non-nucleoside reverse transcriptase inhibitor (NNRTI) which has shown high activity against wild-type human immunodeficiency virus (HIV-1), and HIV strains resistant to other non-nucleotide agents.
The purpose of this study is to evaluate the safety, efficacy, and pharmacokinetics of EZN-2279 in patients with ADA-deficient combined immunodeficiency currently being treated with Adagen.
Evaluation of antiretroviral therapy combining Raltegravir and Maraviroc in patients with virological success, presenting with clinical lipohypertrophy.
Three different white adipose tissue-related disorders, whether due to its excess (obesity), absence (lipoatrophies) or aberrant distribution (lipodystrophies), are paradoxically able to induce metabolic insulin resistance syndrome. The respective roles played by quantitative and qualitative anomalies of adipose tissue, gluco- and lipo-toxicity, liver and muscle insulin resistance, low-grade fat inflammation and immune alterations are not yet perfectly understood. In contrast to most organ transplantations that are often complicated by post-transplantation diabetes, diabetes cell therapy is associated with body weight loss, which is possibly related to the antiadipogenic effects of mTOR inhibitors (rapamycin or sirolimus). The aim of this study is thus to determine and monitor blood interleukin-7 and other cytokine levels; metabolic parameters; and fat mass distribution with DEXA and RMN, before and after a immunosuppressive regimen in patients receiving different kinds of transplantation (liver, kidney or islets) with normal weight and no type 2 diabetes before transplantation. In these patients, blood samples will be taken before and after transplantation, as will adipose tissue during the transplantation surgery, in order to constitute a plasma serum, gene and tissue bank for improving our knowledge of disorders linking fat mass, insulin resistance and immunity, especially post-transplantation diabetes.
The purpose of the study is to develop a 20% subcutaneous immunoglobulin treatment option for patients with primary immunodeficiency (PID) diseases.
