Filter by:This is a study to evaluate the efficacy and safety of three experimental drugs compared with telaprevir (a licensed product) in people with hepatitis C virus infection who have not had treatment before.
Human respiratory syncytial virus (RSV) is a common cause of respiratory illness in infants and children. This study will evaluate the safety and immune response to an RSV vaccine in healthy RSV-naïve children.
Since October 2009, H1N1 influenza vaccine has developed and approved of immunization in population in China. However, there was little epidemiological evidence of safety when vaccinated in healthy pregnant women. The main objective of this study is to assess the safety of split-virion inactivated H1N1 vaccine without adjuvant when administered in healthy pregnant women. It is a stratified and controlled clinical trial in healthy pregnant women. And participants were included up to 226 healthy pregnant women aged 18 -35 years old who have no history of novel influenza H1N1 infection or novel influenza H1N1 vaccination. The pregnancy week ranged from 5 weeks to 32 weeks. Subjects were divided into 2 groups: vaccinated group（122） and unvaccinated group（104）. Subjects in the vaccinated group were administered one dose of 15μg H1N1 vaccine. Subjects in the unvaccinated group received no vaccine as controls. Safety will be measured by assessment of pregnancy outcomes. And observation time for pregnancy outcomes was lasting for 28 days postpartum since vaccinated; and protective effect was observed for six months.
To evaluate the immune response and the safety of a primary series schedule that includes V419 (PR5I) at 2 and 6 months of age and Pediacel at 4 months of age Primary objectives - To demonstrate that the mixed schedule induces acceptable responses for Hepatitis B (HB) one month after completion of the mixed schedule - To demonstrate that the mixed schedule induces acceptable responses for Haemophilus influenzae type b (Hib) one month after completion of the mixed schedule Secondary objectives - To describe the antibody response to all PR5I antigens one month after completion of the mixed schedule - To describe the antibody response to meningococcal serogroup C (MCC) conjugate vaccine one month after the second dose of MenC vaccine - To describe the safety profile after each dose of study vaccines administered
Primary Series Primary objectives - To demonstrate that the concomitant administration of the hexavalent vaccine with a meningococcal serogroup C conjugate vaccine is non inferior to the administration of the hexavalent vaccine without a MenC vaccine concomitantly in term of seroprotection rate for hepatitis B one month after the third dose of the hexavalent vaccine - To demonstrate that the concomitant administration of a MenC vaccine with the hexavalent vaccine induces an acceptable response for MenC in term of seroprotection rate (SPR) one month after the second dose of MenC Booster Primary objectives - To describe the immunogenicity of a booster dose of the hexavalent vaccine and of a meningococcal group ACWY conjugate (MenACWY) vaccine either co-administered at 12 months of age or given separately.
Infectious morbidity and mortality is a major complication of AML (Acute Myeloid Leukemia) induction and consolidation chemotherapies related aplasia. The main aim of this study is to measure incidence of respiratory viral infections during AML induction and consolidation chemotherapy related aplasia. Primary end point is a positive polymerase chain reaction(PCR)associated with clinical signs.
The purpose of the study is to determine if physician education coupled with audit and feedback of antibiotic prescribing can improve antibiotic prescribing by primary care clinicians.
In this study we are testing a new vaccine against Respiratory Syncytial Virus (RSV). This virus can cause respiratory infections such as bronchiolitis and pneumonia. It affects all ages, but especially infants, adults with a suppressed immune system, and the elderly. RSV only infects humans and occurs in epidemics each winter. It is the single most common cause of severe respiratory illness in children. There is no effective anti-viral medication to treat RSV infections. There is a monoclonal antibody, which can be given to 'at-risk' children given by injection on a monthly basis during winter to provide short term protection against infection, but it is only partially effective and prohibitively expensive. Currently, there is no licensed vaccine to prevent RSV infection and there remains a real need to develop a vaccine as a cost-effective method to save lives and reduce the cost of disease caused by RSV.
Each year, an estimated 230,000 HIV-infected women in need of services for prevention of mother-to-child transmission of HIV (PMTCT) give birth in Nigeria, more than in any other nation in the world. Vanderbilt University (VU), through its affiliate, Friends in Global Health (FGH), is currently supporting HIV/AIDS services in North-Central Nigeria. These sites are predominantly rural primary health centers (PHCs) where shortages of high-cadre health care providers and insufficient laboratory capacity to perform CD4+ cell count testing have been major barriers to effective PMTCT scale-up. A systematic reassignment of patient care responsibilities coupled with the adoption of point-of-care (POC) CD4+ cell count testing will facilitate the ability of lower-cadre health providers to manage PMTCT care, including the provision and scale-up of antiretroviral treatment (ART) to pregnant women in these rural, decentralized sites. A system wherein men are facilitated to accompany their wives to ANC appointments will create an important opportunity to address entrenched gender norms. The investigators therefore propose using community and facility-based measures to encourage male partners to accompany their spouses for ANC. As influential community members, male partners can assist their spouses to utilize culturally-sensitive, sustainable and integrated PMTCT care provided by lower-cadre providers in these resource-constrained settings. The investigators propose a parallel, cluster randomized trial to evaluate the impact of a family-focused PMTCT package that includes: 1) task-shifting to lower-cadre providers at PMTCT sites; 2) POC CD4+ cell count testing; (3) integrated mother-infant care; and (4)) a prominent role for influential family members (male partners), working in close partnership with community-based health workers/volunteers. The specific aims of this study are: 1. To evaluate whether implementation of the integrated PMTCT package in primary level antenatal clinics (ANC) increases the proportion of eligible pregnant women who initiate antiretroviral medications for the purposes of PMTCT. The investigators hypothesize that the provision of the PMTCT package in intervention clinics will improve PMTCT antiretroviral uptake rates among eligible women during pregnancy from 40% to 65%. 2. To determine whether implementation of the PMTCT package improves postpartum retention of mother-infant pairs at 6 and 12 weeks. The investigators hypothesize that postpartum retention rates among mother-infant pairs attending intervention sites will be >20% higher at 6 weeks when compared to mother-infant pairs receiving care in non-intervention sites. 3. Conduct a cost-effectiveness analysis (CEA) of the impact of this novel PMTCT intervention compared to the existing standard-of-care referral model. The investigators hypothesize that the proposed intervention will be more cost-effective than the existing model of care. In addition, two qualitative evaluations will be conducted in order to: 1. Assess client satisfaction with health services, comparing PMTCT services provided by lower level vs. higher level cadre health workers; and 2. Evaluate health care worker satisfaction with the new PMTCT service delivery model.
This clinical study is looking at a vaccine called MVA-EBNA1/LMP2. This is a new vaccine that has already been studied in small number of cancer patients. The vaccine is designed to boost a patient's immunity against a common virus. The virus is called Epstein Barr virus or EBV. EBV is sometimes found inside cancer cells and is commonly found in nasopharyngeal cancer cells.
