NCT00831012

Brief Summary

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 test the safety of and immune response to a new dengue virus vaccine in healthy adults.

Outcome Measures

Primary Outcomes (2)

  • Determine the safety of a single dose of the rDEN3Δ30/31-7164 vaccine, as assessed by the frequency, severity, and seriousness of vaccine related adverse events (AEs).

    Throughout study

  • Determine the immunogenicity of a single dose of the rDEN3delta30/31-7164 vaccine, as assessed by neutralizing antibody titers to DEN3 at 4 weeks and 6 weeks after vaccination

    Throughout study

Secondary Outcomes (7)

  • Assess the frequency, quantity, and duration of viremia after a single dose of vaccine

    Throughout study

  • Determine the number of vaccinees infected with rDEN3delta30/31-7164. Infection is defined as recovery of vaccine virus from the blood or serum of a volunteer and/or by seroconversion to DEN3 (a ≥4-fold rise in DEN3 neutralizing antibody titers).

    Throughout study

  • Compare the infectivity rates, safety, and immunogenicity of a single dose of rDEN3delta30/31-7164 vaccine between the dose level groups.

    Throughout study

  • Determine the durability of antibody response 26 weeks after vaccination

    At 26 weeks

  • Obtain an estimate for the Human Infectious Dose-50% (HID50) if dose dependent infectivity is observed

    Throughout study

  • +2 more secondary outcomes

Study Arms (2)

Group 1

EXPERIMENTAL

Group 1 will consist of healthy participants receiving an immunization of 10\^3 PFU rDEN3delta30/31-7164

Biological: rDEN3delta30/31-7164

Group 2

EXPERIMENTAL

Group 2A will consist of healthy participants who will receive an immunization of 10\^5 PFU of rDEN3delta30/31-7164 vaccine or placebo. Group 2A participants will be enrolled if less that 90% of Group 1 participants seroconvert to DEN3 by Study Day 42. Group 2B will consist of healthy participants who will receive an immunization of 10\^1 PFU of rDEN3delta30/31-7164 vaccine or placebo. Group 2B participants will be enrolled if more that 90% of Group 1 participants seroconvert to DEN3 by Study Day 42.

Biological: rDEN3delta30/31-7164

Interventions

A live attenuated, recombinant DEN3 candidate vaccine virus

Eligibility Criteria

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

You may qualify if:

  • Adult male or non-pregnant female between 18 and 50 years of age, inclusive.
  • Good general health as determined by physical exam, laboratory screening, and review of medical history
  • Available for the duration of the study, approximately 26 weeks post-vaccination
  • Willing to use effective means of contraception for the duration of the trial

You may not qualify if:

  • 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 volunteer to understand and cooperate with the requirements of the study protocol
  • Grade 1 or above values for absolute neutrophil count (ANC), alanine aminotransferase (ALT), and serum creatinine, as protocol defined
  • Any other condition that in the opinion of the investigator would jeopardize the safety or rights of a volunteer participating n the trial or would render the volunteer unable to comply with the protocol
  • Any significant alcohol or drug abuse in the past 12 months which has caused medical, occupational, or family problems, as indicated by volunteer history
  • History of a severe allergic reaction or anaphylaxis
  • Severe asthma (emergency room visit or hospitalization within the last 6 months)
  • Positive HIV-1 serology by screening and confirmatory assays
  • Positive for hepatitis C virus (HCV) by screening and confirmatory assays
  • Positive for hepatitis B virus (HBV) by hepatitis B surface antigen (HBsAg) screening
  • Any known immunodeficiency syndrome
  • Use of corticosteroids (excluding topical or nasal) or immunosuppressive drugs within 30 days prior to Study Day 0
  • Receipt of a live vaccine within 4 weeks or a killed vaccine within the 2 weeks prior to Study Day 0 or anticipated receipt of any vaccine during the 42 days following Study Day 0
  • History of a surgical splenectomy
  • Receipt of blood products within the past 6 months, including transfusions or immunoglobulin or anticipated receipt of any blood products or immunoglobulin during the 42 days following Study Day 0
  • +5 more criteria
