Filter by:The aim of the trial was to assess the efficacy of the CYD dengue vaccine in preventing symptomatic, virologically-confirmed dengue (VCD) cases. Primary Objective: To assess the efficacy of CYD dengue vaccine after 3 vaccinations at 0, 6, and 12 months in preventing symptomatic VCD cases, regardless of the severity, due to any of the four serotypes in children aged 2 to 14 years at the time of inclusion. Secondary Objectives: - To describe the efficacy of CYD dengue vaccine in preventing symptomatic VCD cases after the third dose to the end of the Active Phase, after at least 1 dose, and after 2 doses. - To describe the occurrence of serious adverse events (SAEs), including SAEs of special interest in all participants throughout the trial period. - To describe the occurrence of hospitalized virologically-confirmed dengue (VCD) cases and the occurrence of severe (clinically-severe or as per World Health Organization (WHO) criteria) VCD cases, throughout the Surveillance Expansion period (SEP) and throughout the trial (from Day 0 to the end of the study). - To describe the antibody response to each dengue serotype after Dose 2, after Dose 3, and 1 and 5 years after Dose 3.
The purpose of this study was to evaluate the safety and immunogenicity of Phase III lots of the CYD dengue vaccine in a pediatric population in Malaysia. Primary Objectives: - To describe the safety (in terms of solicited and unsolicited adverse events) of the CYD dengue vaccine in all participants after each injection. - To describe the antibody response to each dengue virus serotype post-injection 2 and post-injection 3.
The purpose of this study is to generate immunogenicity and safety data in preparation for efficacy studies in Latin America. Primary Objectives: - To describe the immune response to dengue viruses before and after each vaccination with CYD dengue vaccine. - To evaluate the safety of each vaccination with CYD dengue vaccine.
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.
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 hemorrhagic fever (DHF) and dengue shock syndrome (DSS) are among the leading causes of pediatric hospitalization in Asia.Mortality rates range from 1% at centres experienced in fluid resuscitation, to upto 44% in established shock.The mainstay of DSS treatment is prompt, vigorous fluid resuscitation with isotonic crystalloid solutions, followed by plasma or colloid solutions for profound or continuing shock. However, this administration is often associated with fluid overload and induces edema in these patients. Hence, we planned a parallel, randomized controlled trial comparing the efficacy and safety of solution containing half molar sodium lactate (Totilac™) with standard treatment(isotonic crystalloid Ringer's Lactate) in pediatric Dengue Shock Syndrome patients, using plasma soluble Vascular Cell Adhesion Molecule(sVCAM-1) levels as an indicator. Hypertonic solutions restore hemodynamic status rapidly with increased cardiac performance and improved tissue perfusion. This is obtained with much smaller volumes.We plan to assess the efficacy and safety of hypertonic sodium lactate in resuscitation of DHF/DSS patients.
Infection with dengue viruses is one of the leading causes of hospitalization and death in children in several tropical Asian counties. The World Health Organization (WHO) estimates that these viruses are responsible for more than 50 million cases of dengue fever (DF) and approximately 0.5 million cases of the more severe disease, dengue hemorrhagic fever/ shock syndrome (DHF/DSS) annually. Because dengue viruses are endemic in most tropical and subtropical regions, keeping more than 2 billion persons at risk for acquiring dengue, the WHO has made development of a dengue vaccine a top priority. The purpose of this study is to evaluate the safety and effectiveness of a candidate DEN4 vaccine aimed at preventing infection with dengue virus serotype 4.
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.
This trial evaluated the use of a tetravalent vaccine against dengue. Primary objectives: - To describe the humoral immune response to dengue before and after each vaccination with tetravalent dengue vaccine in adults, adolescents, and children. - To evaluate the safety of each vaccination with tetravalent dengue vaccine in the 4 age cohorts. - To evaluate the persistence of antibodies against dengue during 5 years after the first vaccination with tetravalent dengue vaccine in the 4 age cohorts.
