NCT ID: NCT00788151 Completed - Dengue Fever Clinical Trials

Study of ChimeriVax™ Tetravalent Dengue Vaccine in Healthy Peruvian Children Aged 2 to 11 Years

Start date: September 26, 2008
Phase: Phase 2
Study type: Interventional

The aim of the trial was to evaluate the use of a tetravalent vaccine, CYD dengue vaccine, against dengue disease. Primary Objectives: - To describe the humoral immune response to dengue before and after each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years) previously vaccinated with yellow fever (YF) vaccine. - To evaluate the safety of each vaccination with dengue vaccine in two age cohorts of children (6 to 11 years and 2 to 5 years). - To describe viremia after the first and second vaccinations with dengue vaccine in a subgroup of 130 randomized participants (100 participants in Dengue Vaccine Group and 30 participants in Control Group) in two age cohorts of children (6 to 11 years and 2 to 5 years).

Start date: August 2008
Phase: Phase 2
Study type: Interventional

This is part of an ongoing effort to develop a satisfactory dengue vaccine: Primary objective: To describe the safety after each vaccination with bivalent and tetravalent formulations of dengue vaccine candidates. To describe the immune response after each vaccination of dengue vaccine.

NCT ID: NCT00730288 Completed - Dengue Clinical Trials

Study of ChimeriVax™ Dengue Tetravalent Vaccine in Adult Subjects

Start date: August 2006
Phase: Phase 2
Study type: Interventional

To evaluate effect of previous flavivirus exposure on the safety and immunogenicity of the ChimeriVax™ dengue tetravalent vaccine Primary Objectives: - To describe the safety of one injection of ChimeriVax™ dengue tetravalent vaccine. - To describe the immune response against dengue before and after one injection of ChimeriVax™ dengue tetravalent vaccine

NCT ID: NCT00712803 Completed - Dengue Clinical Trials

Safety of and Immune Response to a Dengue Virus Vaccine (rDEN3-3'Ddelta30) in Healthy Adults

Start date: December 2008
Phase: Phase 1
Study type: Interventional

Dengue fever, which is caused by dengue viruses, is a major health problem in tropical and subtropical regions of the world. The purpose of this study is to evaluate the safety of and immune response to a new dengue virus vaccine in healthy adults.

NCT ID: NCT00688389 Recruiting - Dengue Fever Clinical Trials

Investigation of the Immuno-regulation and Viral Hepatitis Among Patients With or After Dengue Fever Infection

Start date: July 2007
Phase:
Study type: Observational

The study will collect the blood samples from 350 healthy persons and 350 persons infected with dengue fever.

NCT ID: NCT00629356 Withdrawn - Dengue Clinical Trials

Follow-up the Health Condition , Investigation of the Immuno-regulation , and the Study for Interaction of Viral Hepatitis--- Among Patients With or After Dengue Fever Infection

Start date: July 2007
Phase: N/A
Study type: Observational

Originally test host's to understand the tracking healthily and immune change of the dengue fever in Taiwan. Blood drawing 20 c.c for liver examination, kidney and other biochemical function, analyze host immunity adjusts and controls the gene, and the reciprocation that may be produced with the virus hepatitis, besides collected 10 c.c urine at the same time. Urine check is in order to compare acute infect and infected over three month person, the change of chemical composition. This plan expect to collect 150 healthy, 150 dengue fever infected and 150 dengue fever bleed hot or dengue fever shock disease group's patient, goal to understand health state and immunity of follow-up adjust and control the difference of the gene and the reciprocation may produce to virus hepatitis of light disease and serious disease.

NCT ID: NCT00617344 Completed - Dengue Fever Clinical Trials

Immunogenicity and Safety of Three Formulations of Dengue Vaccines in Healthy Adults Aged 18 to 45 Years in the US

Start date: April 17, 2008
Phase: Phase 2
Study type: Interventional

This study used 3 different formulations of tetravalent CYD dengue vaccine. The primary objective of the study was to evaluate the neutralizing antibody response after 2 doses of two different formulations of tetravalent dengue vaccine administered at Month 0 and Month 6. The secondary objectives were: - To evaluate the safety of the 3 formulations of tetravalent CYD dengue vaccine. - To describe the neutralizing antibody responses to each of the 3 vaccine formulations. - To describe vaccine viremia after the first and second dose of each of the 3 vaccine formulations in a subset of participants.

NCT ID: NCT00473135 Completed - Dengue Clinical Trials

Safety of and Immune Response of a 2-dose Regimen of rDEN1delta30 Dengue Virus Vaccine

Start date: May 2007
Phase: Phase 1
Study type: Interventional

Dengue fever, caused by dengue viruses, is a major health problem in tropical and subtropical regions of the world. The purpose of this study is to evaluate the safety of and immune response to a 2-dose regimen of a new monovalent dengue virus vaccine. This study will test the dengue virus vaccine DEN1delta30 in healthy adults.

NCT ID: NCT00468858 Completed - Dengue Fever Clinical Trials

A Study of Two Doses of WRAIR Dengue Vaccine Administered Six Months Apart to Healthy Adults and Children

Start date: July 2007
Phase: Phase 2
Study type: Interventional

The purpose of this study is to evaluate the safety and effectiveness of two different formulations of an investigational dengue vaccine (T-DEN) against a placebo vaccine when two doses are given six months apart to adults and children.

NCT ID: NCT00458120 Completed - Clinical trials for Dengue Hemorrhagic Fever

Safety of and Immune Response to Two Different Dengue Virus Vaccines in Individuals Previously Immunized Against Dengue Virus

Start date: March 2007
Phase: Phase 1
Study type: Interventional

Dengue fever, which is caused by dengue viruses, is a major health problem in subtropical regions of the world. There are four different forms (serotypes) of dengue virus that can cause dengue fever. The purpose of this study is to determine the safety and immune response to a vaccine containing a particular dengue serotype when an individual has been previously vaccinated with a different dengue serotype.
