Filter by:The purpose of this study is to determine how drug abuse treatment interventions can be integrated with established Human Immunodeficiency Virus prevention approaches to optimize their combined effectiveness.
This study of Kaletra (Lopinavir (LPV)/Ritonavir (RTV)) tablets will be conducted to clarify the following with regard to treatment with this drug: 1. Incidence and conditions of occurrence of adverse reactions in the clinical setting 2. Factors that may affect the safety and effectiveness of Kaletra (QD)
The purpose of this trial is to assess the antiviral activity and safety of a dolutegravir (DTG) containing regimen in HIV-1 infected, antiretroviral therapy (ART)-experienced adults with current or historical failure on an integrase inhibitor (INI) containing regimen. The study will assess DTG 50mg twice daily administered initially with the current failing ART regimen but then with an optimised background ART regimen (OBR) after Day 7. The first analyses will be conducted after the last subject enrolled has completed 24 weeks. Subjects may remain on study after Week 24.
This study will collect information on health status and risk behaviors, as well as basic demographic and biomedical information for a group of HIV positive adolescents receiving care at sites newly participating in ATN III.
Aim of the study is to determine optimal time to initiate anti-retroviral therapy in HIV/TB co-infected patients who recently started treatment for Tuberculosis by comparing immediate versus deferred initiation of HAART. The study will address the following questions; - Is it possible to reduce mortality rate and increase survival by early initiation of HAART during TB treatment with out compromising for adverse drug reaction, toxicity and immune reconstitution syndrome? - What is the risk/ benefit ratio between immediate versus deferred initiation of HAART during TB treatment with respect to safety/efficacy of TB and HIV co-treatment? - When is the most appropriate time to start HAART during TB treatment?
This is a prospective, open-label, non-controlled, non-randomised multicentre Phase III study of two multiple-dose intravenous NewGam regimens (every 3 weeks or every 4 weeks, continuing the patient's infusion interval in the main study) for three months.
This is a non-randomized clinical trial using a lentiviral gene transfer vector (or lentivector, LV) to treat patients with X-linked severe combined immunodeficiency (XSCID) who have clinically significant impairment of immunity. We will collect the patient s own stem cells that will be transduced or exposed to the vector carrying a normal copy of the gene. The gene-corrected stem cells will be administered as a one-time infusion. Patients will receive a low-moderate dose of a chemotherapy drug called busulfan (6 mg/kilogram body weight) to allow engraftment of the stem cells. After the infusion, patients will be monitored to see if the treatment is safe and whether their immune system improves. Patients will be monitored for up to 15 years after treatment to assess immune function and the safety of the treatment. XSCID is a genetic disease caused by defects in the common gamma chain, a protein found at the surface of immune cells called lymphocytes, and is necessary to their growth and function. XSCID patients cannot make T-lymphocytes necessary to fight infections, and their B-cells fail to make essential antibodies. Without normal T-and B-lymphocyte function, patients develop fatal infections in infancy unless they receive a bone marrow transplant from a healthy donor. The best type of transplant is from a tissue-matched healthy sibling, but most XSCID patients do not have a tissue-matched sibling and are treated with a transplant from a parent who is only half-matched by tissue typing. While a half-matched transplant from a parent can be lifesaving for an infant with XSCID, a subset of patients fail to achieve sufficient long-lasting restoration of immunity to prevent infections and other chronic problems. Trials of gene transfer treatments using mouse retrovirus vectors for infants with XSCID have been performed and have shown this type of gene transfer can be an alternate approach for significantly restoring immunity to infants with XSCID. However, among the 18 infants with XSCID benefiting long-term from the gene transfer treatment, 5 developed T-lymphocyte leukemia and 1 died of this leukemia. When older children with XSCID were treated with gene transfer, the restoration of immunity was much less than seen in the infants. These observations of gene transfer treatments using mouse retrovirus vectors to treat infants and older patients with XSCID suggest that safer and more effective vectors were needed and that there also may be a need to give chemotherapy or another mode of conditioning to increase engraftment in the marrow of the gene-corrected blood stem cells. Our data and other published studies suggest that lentivectors derived from the human immunodeficiency virus and have the properties of our highly modified vector have a reduced interaction with nearby genes and therefore less of a tendency to activate genes that may lead to cancer formation. This type of lentivector may work better at getting into blood stem cells. The study's purpose is to evaluate the safety and effectiveness of lentiviral gene transfer treatment in restoring immune function to 35 XSCID patients who are 2 to 40 years of age and have significant impairment of immunity. Early evidence for effectiveness will be defined by appearance and expansion in the circulation of the patient s gene-corrected T-lymphocytes with a functional >=c gene and improved laboratory measures of immune function. The primary endpoint for efficacy will be at 2 years after treatment and will include these laboratory parameters plus evidence for clinical benefit. Evidence for safety will focus on the maintenance of a diversity of gene-marked cells and no occurrence of abnormal patterns of production of blood cells or any leukemia or other cancer. ...
The purpose of this study is to evaluate the acceptability and efficacy of a computer-based tailored information application designed to promote health literacy in persons treated for HIV infection. The study hypothesis is that the application will be acceptable and usable for persons treated for HIV infection, and will improve their levels of adherence to antiretroviral medication treatment.
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 main objective is to determine the efficacy of Gammaplex by measuring the number of serious acute bacterial infections during treatment with Gammaplex over a 12 month period. The secondary objectives are to assess the safety and tolerability of Gammaplex and to compare the data collected from adult subjects with PID from the GMX01 study
