Filter by:The aim of this study is to evaluate the clinical efficacy and safety of inhaled zanamivir in treatment of influenza A and B virus infections in China.
The purpose of this study is to compare the results for HIV and/or Hepatitis C Virus antibody testing when using routine plasma versus SMARTplasma from the same blood sample. SMARTplasma is enriched for antibodies via a stimulation step of whole blood in a SMARTube™ (SMARTstim™ in the USA).
The objective is to establish that APTIMA HPV Assay performance on the PANTHER System is comparable to performance on the TIGRIS System.
This is a research study to evaluate the safety, tolerability and anti-viral activity of GS-9669 in patients with Hepatitis C infection.
The thirty-six-month immunogenicity evaluation of Quadrivalent HPV (Types 6, 11, 16, 18) L1 Virus-Like Particle (VLP) Vaccine in Chinese female subjects aged 9 to 45 years and male subjects aged 9 to 15 years.
A randomized, placebo-controlled, double-blind clinical trial is to evaluate the safety and immunogenicity of a new inactivated EV71 vaccine developed by Sinovac Biotech CO., LTD.
The purpose of this study is to compare Live Attenuated Japanese Encephalitis Chimeric Virus Vaccine (IMOJEV™) with Japanese encephalitis live attenuated vaccine (SA14 14 2 vaccine [CD.JEVAX™]) after a single dose vaccination to support product registration. Primary Objective: - To demonstrate the non-inferiority of the antibody response 28 days after administration of one dose of IMOJEV™ compared to the antibody response 28 days after administration of one dose of the CD.JEVAX™ control vaccine. Secondary Objectives: - To describe the immune response to Japanese encephalitis (JE) in both vaccine groups using 50% plaque reduction neutralization assay (PRNT50) assays before and after a single dose of IMOJEV™ vaccine or a single dose of CD.JEVAX™ vaccine. - To describe the safety of vaccination in all subjects up to 28 days and all serious adverse events up to 6-month after vaccination.
To develop a real-time diagnostic technique with e- Ab sensor for high risk human papilloma viruses(high risk HPV) detection, the investigators conduct a prospective clinical study. In comparison with results from direct sequencing of HPV, the investigators evaluate the performance of e- Ab sensor, including reproducibility, sensitivity, specificity, and cross-reaction (such as detection of low risk HPV). The potential factors which may interfere with the results would be investigated. With such a real-time diagnostic technique, the investigators hope to obtain information of patients in cost-saving and time-saving way and can give patients early treatment and offer more individualized treatment for our patients.
This is a Phase 2, randomized, open-label exploratory study that will examine the antiviral efficacy, safety, and tolerability of Response guided treatment (RGT) with GS-5885 + GS-9451 + PEG/RBV (6 or 12 weeks), or Peginterferon Alfa 2a (PEG)/Ribavirin (RBV)alone (24 weeks) in treatment naïve subjects with chronic Hep C (HCV) infection with genotype (GT) 1 and IL28B CC genotype.
Both twice-a-day (BID) and once-a-day (QD) dosing are approved in Europe for the protease inhibitor lopinavir/ritonavir (LPV/r; Kaletra®). Since once-a-day dosing is actually a driver for human immunodeficiency virus (HIV)-infected patients to request a specific antiretroviral, the aim of this study is to assess both patient's perception of and adherence to Kaletra once-a-day, as well as with which factors they are related.
