NCT01436422

Brief Summary

Dengue viruses can cause dengue fever and other serious health conditions, primarily affecting people living in tropical regions of the world. This study will evaluate the safety and immune responses to two formulations of a tetravalent dengue virus vaccine in healthy adults.

Outcome Measures

Primary Outcomes (3)

  • Safety of two TetraVax-DV admixtures, as assessed by the frequency of vaccine-related adverse events (AEs), graded by severity

    Measured through Day 360

  • Immunogenicity of two TetraVax-DV admixtures, as assessed by neutralizing antibody titers to DEN1, DEN2, DEN3, and DEN4

    Monovalent, bivalent, trivalent, and tetravalent seropositivity and seroconversion rates will be determined at 28, 56, and 90 days after each vaccination.

    Measured through Day 180 after each vaccination

  • Seropositivity in those vaccinees who remained seronegative to one or more DENV serotypes following the first vaccination and who recieved a second dose of vaccine given at Day 180

    Measured through Day 360

Secondary Outcomes (10)

  • Frequency of viremia following vaccination

    Measured through Day 360

  • Number of vaccinees infected with DEN1, DEN2, DEN3, and DEN4

    Measured through Day 360

  • Duration of the neutralizing antibody response 26 weeks after each vaccination

    Measured 26 weeks after each vaccination

  • Ability of a second dose of vaccine to boost serum neutralizing antibody titers by Day 270

    Measured at Day 270

  • Evaluate the phenotype of peripheral blood mononuclear cells at primary infection with the TetraVax-DV vaccine

    Measured through Day 360

  • +5 more secondary outcomes

Eligibility Criteria

Age18 Years - 50 Years
Sexall
Healthy VolunteersYes
Age GroupsAdult (18-64)

You may qualify if:

  • In good general health, as determined by physical examination, laboratory screening, and review of medical history
  • Available for the duration of the study, approximately 26 weeks post-vaccination
  • Willing to participate in the study as evidenced by signing the informed consent document
  • Female participants of childbearing potential must be willing to use effective contraception for the duration of the trial. More information on this criterion can be found in the protocol.

You may not qualify if:

  • Currently pregnant (as determined by positive beta-human choriogonadotropin \[HCG\] test) or breastfeeding
  • Evidence of clinically significant neurologic, cardiac, pulmonary, hepatic, rheumatologic, autoimmune, or renal disease by history, physical examination, and/or laboratory studies
  • Behavioral, cognitive, or psychiatric disease that in the opinion of the investigator affects the ability of the participant to understand and cooperate with the requirements of the study protocol
  • Screening laboratory values of Grade 1 or above for absolute neutrophil count (ANC), alanine aminotransferase (ALT), and serum creatinine, as defined in the protocol
  • Any other condition that in the opinion of the investigator would jeopardize the safety or rights of a participant in the trial or would render the participant unable to comply with the protocol
  • Any significant alcohol or drug abuse in the 12 months prior to study entry that has caused medical, occupational, or family problems, as indicated by a participant's history
  • History of a severe allergic reaction or anaphylaxis
  • Severe asthma (emergency room visit or hospitalization within the 6 months prior to study entry)
  • HIV infection, by screening and confirmatory assays
  • Hepatitis C virus (HCV) infection, by screening and confirmatory assays
  • Hepatitis B virus (HBV) infection, by hepatitis B surface antigen (HBsAg) screening
  • Any known immunodeficiency syndrome
  • Use of anticoagulant medications
  • Use of corticosteroids (excluding topical or nasal) or immunosuppressive drugs within 42 days prior to or following vaccination. Immunosuppressive dose of corticosteroids is defined as greater than or equal to 10 mg prednisone equivalent per day for greater than or equal to 14 days.
  • Receipt of a live vaccine within 28 days or a killed vaccine within the 14 days prior to vaccination or anticipated receipt of any vaccine during the 42 days following vaccination
  • +36 more criteria
