Vicriviroc (vye-kri-VYE-rock) is an investigational drug (not yet approved by Government Regulatory Authorities for commercial use) that belongs to a new class of drugs, called CCR5 receptor blockers. This group of drugs blocks one of the ways HIV enters T-cells (the cells that fight infection). Previous smaller studies in HIV treatment-experienced patients, have shown that vicriviroc is safe and effective. The purpose of this study is to confirm the previous findings in a larger phase 3 study over a 48-week period, and show that when taken in combination with other appropriate HIV drugs, vicriviroc can decrease the level of HIV (viral load) in the blood and that it is well tolerated.
The purpose of this study is to measure the pharmacokinetics, efficacy and safety of Immune Globulin Intravenous (Human) [IGIV], 5% Solution Omr-IgG-am™ in patients with primary immunodeficiency diseases.
Main objective: - To evaluate the applicability of the treatment: 1. To evaluate the treatment toxicity according to the Common Terminology Criteria (CTC) version 3.0 of the National Cancer Institute (NCI). 2. To evaluate opportunistic and non-opportunistic infections after 6 cycles of treatment with rituximab plus cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) administered every 14 days and highly active antiretroviral therapy (HAART) in patients with diffuse large B cell lymphoma (DLBCL) and HIV infection. 3. To evaluate the adherence to the treatment with 6 cycles of R-CHOP considering the delays in the administration of the cycles and the reductions in the doses of chemotherapy (planned dose administered in predicted term). Secondary objectives: - To evaluate the efficacy of the treatment in patients with DLBCL and HIV infection after 6 cycles of treatment with R-CHOP administered every 14 days (R-CHOP/14): 1. To determine the global response and complete remission tax. 2. To evaluate the duration of the response. 3. To evaluate the probability of event-free survival in 5 years. 4. To evaluate the probability of global survival in 5 years. - To identify predictive factors of response after 6 cycles of treatment with R-CHOP administered every 14 days in patients with DLBCL and HIV infection. - To evaluate the impact of the therapeutic combination of R-CHOP and HAART in the parameters of the HIV infection (HIV viral load and CD4+ lymphocyte count).
The purpose of the study is to compare the efficacy, safety and tolerability of darunavir/ritonavir 800/100 mg once a day (O.D.) as a monotherapy versus a triple combination therapy containing 2 nucleosides and darunavir/ritonavir in 250 HIV-1 infected patients who have been on Highly Active Antiretroviral Therapy (HAART) and have plasma viral load below 50 copies/ml for at least 24 weeks.
This is a study to determine the prevalence of a genetic marker, HLA-B5701, in the UK population. HLA-B*5701 has been strongly associated with the risk of an allergic reaction to a HIV medicine, Abacavir. The allergic reaction is known as a hypersensitivity reaction. The study is a prospective study inviting HIV-1 positive patients over the age of 18 years to participate. Each participant will complete one study visit. They will be asked for details of their background including their age, sex, ethnicity, country of origin and parental country of origin. They will be asked to give two samples to test for the presence of the genetic marker HLA-B*5701. The two samples are: - A cheek swab - A blood sample In selected centres patients may be asked to provide up to two additional blood samples. These samples will be used to help develop and validate new methods of determining HLA-B*5701 testing.
This is a Phase IIIB, 48 Week, multicentre, randomized, open-label, parallel group study comparing the safety and efficacy of fosamprenavir plus ritonavir 1400mg/100mg once-daily to fosamprenavir plus ritonavir 700mg/100mg twice-daily, both administered with abacavir/lamivudine 600mg/300mg once-daily in antiretroviral-naive HIV-1 infected adults. This study utilizes a group-sequential design with two stages: 1) an interim 24 week cohort analysis of approximately 200 subjects and 2) if study continuation criteria are met at this interim analysis, further enrolment of an additional 528 subjects, followed over a minimum of 48 weeks. The objectives of the study are to demonstrate 1) non-inferior antiviral activity of fosamprenavir/ritonavir 1400mg/100mg QD compared to fosamprenavir/ritonavir 700mg/100mg BID and 2) a superior fasting non-HDL lipid profile in subjects receiving fosamprenavir/ritonavir 1400mg/100mg QD.
This study evaluates an interactive computer counseling tool to help HIV-positive individuals develop an integrated health promotion plan incorporating antiretroviral (ART) adherence and HIV transmission risk reduction. We hypothesize that evidence-based counseling for ART adherence support and for HIV transmission risk reduction can be delivered effectively in a self-administered computer tool.
This study is a cross sectional observational study to evaluate the prevalence of HLA-B*5701 in the major French ethnotypes. Any HIV-1 infected subject will be eligible for this study including antiretroviral therapy (ART) naÃ-ve and experienced subjects irrespective of abacavir use, as well as subjects previously tested for HLA-B*5701. Subjects will be approached during a standard clinic visit, and all subjects will be consented prior to any study specific procedure. Subjects will be asked to provide a tissue sample (cheek cells and blood sample) which will be used to assess HLA-B*5701 status by central and local methodologies.
This study was designed to test the efficacy, safety, tolerability and durability of the antiviral response between atazanavir (ATV) + ritonavir (/r) + abacavir/lamivudine(ABC/3TC) Fixed dose combination (FDC) each administered once daily (QD) for 36 weeks followed by randomization to either a simplification regimen of ATV or continuation of ATV +/r for an additional 48 weeks, each in combination with ABC/3TC in antiretroviral (ART)-naive, HIV-1 infected, HLA-B*5701 negative subjects. All subjects who complete the 84-week study will be eligible to enter the treatment extension phase and continue for an additional 60 weeks. The purpose of this extension is to obtain longer term treatment data in subjects who have completed the 84-week study.
