Filter by:The purpose of this study is to assess the safety of Takeda's Tetravalent Dengue Vaccine Candidate (TDV) (previously DENVax) in healthy adults when given as either a subcutaneous (SC) or intradermal (ID) injection at two dose levels (low and high). The vaccine will be given as two doses 90 days apart. Safety assessments include injection site evaluation and adverse events. The immune response generated after vaccination will be assessed up to 9 months after the first vaccination.
The purpose of this study is to detect acute febrile episodes and dengue infection in five Asian countries, to assess dengue seroprevalence, and to assess surveillance infrastructure at investigational sites in anticipation of a Phase 3 efficacy trial of a vaccine to prevent dengue infection. The primary objectives are: - To identify acute febrile episodes among the cohort in order to detect the presence of dengue infection. - To develop operational infrastructure for potential Phase III dengue efficacy trial sites. - To describe the dengue seroprevalence among the cohort at baseline and at the end of the study.
The purpose of this study was to demonstrate that different CYD dengue vaccine lots manufactured using the same method and in the same location but at different times produce an equivalent immunological response after 3 doses. Primary Objective - To demonstrate that three different Phase III lots of CYD dengue vaccine induce an equivalent immune response in terms of post-Dose 3 geometric mean titers (GMTs) against the four parental serotypes. Secondary Objectives: - To demonstrate that data from one Phase II lot and pooled data from Phase III lots of CYD dengue vaccine show an equivalent immune response in terms of post-Dose 3 GMTs against the four parental serotypes. - To describe the safety of the CYD dengue vaccine in all participants after each dose.
The purpose of this study is to investigate the potential for co-administration of the first dose of CYD Dengue vaccine with childhood vaccination. Primary Objectives: - To describe the safety of CYD Dengue vaccine after each dose; first dose given alone or coadministered with childhood vaccines. Secondary Objectives: - To describe the immunogenicity of CYD Dengue vaccine after each dose; first dose given alone or co-administered with childhood vaccines.
Retrospective data in children with dengue hemorrhagic fever (DHF) and dengue shock syndrome (DSS), and in adults with dengue fever (DF), suggested a lack of benefit from prophylactic platelet transfusion for severe thrombocytopenia in dengue patients without bleeding. However, in Taiwan and Singapore, platelet transfusion was given to 13-50% of hospitalised dengue patients. This is a prospective randomised study to examine the safety and efficacy of prophylactic platelet transfusion in adults with dengue and severe thrombocytopenia without bleeding. The hypotheses are: 1. Prophylactic platelet transfusion is safe in hospitalised dengue patients with severe thrombocytopenia. 2. Prophylactic platelet transfusion is effective in preventing bleeding in hospitalised dengue patients with severe thrombocytopenia.
Primary objectives: - To describe the immune response to each dengue serotype before and after each vaccination with sanofi pasteur's CYD dengue vaccine. - To evaluate the safety of each vaccination with sanofi pasteur's CYD dengue vaccine.
Dengue virus is an arbovirus transmitted by mosquitoes which causes significant morbidity and mortality among children in tropical regions, especially in resource limited countries. The objective of this protocol is to compare the sensitivity and specificity of clinical gestalt and two rapid antigen tests for dengue virus and to compare the gene expression of leukocytes in distinct dengue fever disease phenotypes module-based RNA microarray technology.
This is a single-center, double-blind, randomized, Phase 1 study to assess the safety and tolerability of HBV-001 D1 in healthy adult subjects.
Dengue fever, caused by dengue viruses, is a major health problem in the tropical and subtropical regions of the world. The purpose of this study is to test the safety of and immune response to a new dengue virus vaccine in healthy adults.
Primary Objectives: - To evaluate safety after each CYD Dengue vaccination in terms of injection site and systemic reactogenicity. - To evaluate the occurrence of Serious Adverse Events (SAEs) throughout the trial period. - To evaluate the humoral immune response to each CYD Dengue serotype after each vaccination in a subset of participants. Secondary Objectives: - To evaluate the persistence of the humoral immune response during 4 years after the last vaccination in a subset of participants.
