Filter by:Investigators in the Division of Infectious Diseases and the Departments of Biochemistry and Molecular Biology of The George Washington University Medical Center are carrying out a research study to determine why patients with Human Immunodeficiency Virus (HIV) and Hepatitis C virus (HCV) co-infection (HIV/HCV) have a more rapid and progressive course of HCV infection, leading to fatty infiltration of the liver and cirrhosis.
An open label, multi-centre, non-interventional post-marketing surveillance (PMS) to monitor the safety and efficacy of ZIAGEN® administered in Korean patients according to the prescribing information.
This protocol provides expanded access to bone marrow transplants for children who lack a histocompatible (tissue matched) stem cell or bone marrow donor when an alternative donor (unrelated donor or half-matched related donor) is available to donate. In this procedure, some of the blood forming cells (the stem cells) are collected from the blood of a partially human leukocyte antigen (HLA) matched (haploidentical) donor and are transplanted into the patient (the recipient) after administration of a "conditioning regimen". A conditioning regimen consists of chemotherapy and sometimes radiation to the entire body (total body irradiation, or TBI), which is meant to destroy the cancer cells and suppress the recipient's immune system to allow the transplanted cells to take (grow). A major problem after a transplant from an alternative donor is increased risk of Graft-versus-Host Disease (GVHD), which occurs when donor T cells (white blood cells that are involved with the body's immune response) attack other tissues or organs like the skin, liver and intestines of the transplant recipient. In this study, stem cells that are obtained from a partially-matched donor will be highly purified using the investigational CliniMACS® stem cell selection device in an effort to achieve specific T cell target values. The primary aim of the study is to help improve overall survival with haploidentical stem cell transplant in a high risk patient population by limiting the complication of GVHD.
This study is a Phase II single arm, open-label, multicenter, study of 50 human immunodeficiency virus-1 (HIV) infected adult patients, all of whom will receive etravirine (ETR) 400mg and DRV/r 800/100mg each given orally once daily. This trial is designed to evaluate the efficacy of the aforementioned ARV regimen, as measured by the percentage of patients with HIV RNA <50 copies/mL at 48 weeks, in early treatment-experienced HIV-infected patients. In addition to general safety parameter measurements, this trial will also assess changes in metabolic, inflammatory, immune restoration, and bone markers. Screening will occur over a 6-week period. The primary endpoint will be assessed at Week 48, and the treatment period is 48 weeks. The end of study endpoint will be met by either completing the Week 48 visit, or by early termination from the study for any reason.
This 48 week, phase 2b study in 150 HIV-1 infected antiretroviral therapy experienced adult subjects consists of a dose-ranging evaluation of GSK2248761 at blinded doses of 100 mg and 200 mg once daily with a control arm of open-label etravirine (ETV) 200 mg twice daily. The background ART for all three arms will be darunavir/ritonavir (DRV/r) 600 mg/100 mg twice daily plus raltegravir (RAL) 400 mg twice daily. Antiviral activity, safety, PK, and development of viral resistance will be evaluated.
The objective of this study is to assess the efficacy, safety, tolerability, and pharmacokinetics of a subcutaneous immune globulin (SCIG; IgPro20) in subjects with primary immunodeficiency (PID). In addition, the study will assess the health-related quality of life and pharmacoeconomic aspects related to treatment with IgPro20.
The purpose of this study is to discover if differences in the surface markers of B-cells (antibody producing cells of the immune system) in Common Variable Immune Deficiency (CVID) are related to CVID or its complications/treatment (e.g. bronchiectasis, granulomatous disease, immunoglobulin treatment). The study hypothesis is that the altered B-cell surface markers are related to CVID, and not to the complications or treatment of CVID.
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.
This study is a two-period, double-blind study in healthy adult female subjects. Each subject will participate in an oral contraceptive Run-in period prior to the treatment periods. The length of the Run-in Period will be 28 days or longer, depending on the timing of the subject's menstrual cycle and on whether the subject is taking an OC. Each subject will participate in this run-in period (if needed), followed by two treatment periods. Treatment Periods 1 and 2 must be conducted successively. Subjects will be randomized in a cross-over fashion to either YASMIN with GSK2248761 or Placebo for 10 days and switch GSK2248761 or placebo for another 10 days. Subjects will return to the study center for final follow up evaluations 7 - 14 days after the final dose of study medication.
This study is a prospective evaluation of children with Severe Combined Immune Deficiency (SCID) who are treated under a variety of protocols used by participating institutions. In order to determine the patient, recipient and transplant-related variables that are most important in determining outcome, study investigators will uniformly collect pre-, post- and peri-transplant (or other treatment) information on all children enrolled into this study. Children will be divided into three strata: - Stratum A: Typical SCID with virtual absence of autologous T cells and poor T cell function - Stratum B: Atypical SCID (leaky SCID, Omenn syndrome and reticular dysgenesis with limited T cell diversity or number and reduced function), and - Stratum C: ADA deficient SCID and XSCID patients receiving alternative therapy including PEG-ADA ERT or gene therapy. Each Group/Cohort Stratum will be analyzed separately.
