NCT02433652

Brief Summary

Infection with dengue viruses is the leading cause of hospitalization and death in children in many tropical Asian countries, and the development of a dengue vaccine is a top health priority. This study will evaluate the ability of a single dose of a trivalent dengue vaccine to protect against infection with an attenuated candidate DENV-2 vaccine, administered 6 months after the trivalent dengue vaccine.

Outcome Measures

Primary Outcomes (2)

  • Frequency of trivalent dengue vaccine admixture and rDEN2Δ30-7169-related adverse events (AEs)

    Classified by both severity and seriousness, through active and passive surveillance.

    Measured through Day 360

  • Dengue virus neutralizing antibody titers (measured through blood collection)

    Measured through Day 360

Study Arms (2)

Trivalent dengue vaccine admixture + rDEN2Δ30-7169

EXPERIMENTAL

Participants will receive the trivalent dengue vaccine admixture at Day 0 and the rDEN2Δ30-7169 vaccine at Day 180.

Biological: Recombinant live attenuated trivalent dengue vaccineBiological: rDEN2Δ30-7169 vaccine

Placebo + rDEN2Δ30-7169

EXPERIMENTAL

Participants will receive a placebo vaccine at Day 0 and the rDEN2Δ30-7169 vaccine at Day 180.

Biological: PlaceboBiological: rDEN2Δ30-7169 vaccine

Interventions

Contains 10\^3.3 plaque forming units (PFU)/mL of rDEN1Δ30, 10\^3.3 PFU/mL of rDEN3Δ30/31-7164 and 10\^3.3 PFU/mL of rDEN4Δ30. It is administered in 0.5 mL containing 10\^3.0 PFU of each component.

Eligibility Criteria

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

You may qualify if:

  • Adult male or female between 18 and 50 years of age, inclusive
  • 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-second vaccination
  • Willingness to participate in the study as evidenced by signing the informed consent document
  • Females Only: Female participants of childbearing potential willing to use effective contraception. Reliable methods of contraception include: hormonal birth control, condoms with spermicide, diaphragm with spermicide, surgical sterilization, intrauterine device, abstinence (6 months or longer since last sexual encounter). All female participants will be considered having child-bearing potential except for those with hysterectomy, tubal ligation, tubal coil (at least 3 months prior to vaccination), or post-menopausal status documented as at least 1 year since last menstrual period.

You may not qualify if:

  • Females Only: 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, 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 (ANC), alanine aminotransferase (ALT), and serum creatinine, as defined in this protocol
  • Any 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 past 12 months that has caused medical, occupational, or family problems, as indicated by participant history
  • History of a severe allergic reaction or anaphylaxis
  • Severe asthma (emergency room visit or hospitalization within the last 6 months)
  • HIV infection, by screening and confirmatory assays
  • Hepatitis C virus (HCV) infection, by screening and confirmatory assays
  • Hepatitis B virus (HBV), by HBV surface antigen (HBsAg) screening
  • Any known immunodeficiency syndrome
  • Use of anticoagulant medications
  • Use of corticosteroids (excluding topical or nasal) or immunosuppressive drugs within 28 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 28 days following vaccination
  • +35 more criteria
