About this trial

This is an interventional prevention trial for Diarrhea focused on measuring Prevention of Travelers' Diarrhea

Eligibility Criteria

18 Years - 64 Years (Adult)All SexesAccepts Healthy Volunteers

Inclusion Criteria:

  1. A female or male 18-64 (inclusive) years of age;
  2. In good health as determined by medical history and screening exam;
  3. Females who are post-menopausal, surgically sterile, or have a negative serum/urine pregnancy test at Day 0 and agree not to become pregnant for the duration of study.

Exclusion Criteria:

  1. Abnormalities at physical exam [as determined by the Toxicity Grading Scale (Grade 1-4)];
  2. Laboratory abnormalities [as determined by the Toxicity Grading Scale (Grade 1 4)] at screening;
  3. Participated in research involving investigational product within 30 days before planned date of first vaccination;
  4. Ever received investigational enterotoxigenic E. coli, LT, or LT (R192G) or NasalFlu, Berna Biotech, Ltd;
  5. Women who are pregnant or breastfeeding;
  6. Clinically significant underlying enteric, pulmonary, cardiac or renal disease;
  7. Current seizure disorder;
  8. Current use of immunosuppressive therapy (inhaled steroids are allowed);
  9. Known or suspected alcohol abuse or illicit drug use within the last year;
  10. Positive Serology for HIV-1, HIV-2, HbsAg, or HCV;
  11. Known allergies to any component of the vaccine including adhesives;
  12. An employee of the study site;
  13. An employee of Intercell (global) or an immediate family member;
  14. Visible tattoos or marks (tattoos/scars) at the vaccination areas that would prevent appropriate dermatologic monitoring of the vaccination sites;
  15. Receipt of any routine vaccinations within 7 days prior to, or following, the date of planned study vaccinations.

Outcomes

Primary Outcome Measures

Characterization and Comparison of the Safety of the TD Vaccine System: (1) Solicited and Unsolicited Adverse Events (AEs) (2) Clinical Laboratory Safety (3) Serious AEs
Erythema, rash, pain, pruritus, hyperpigmentation, hypopigmentation and edema were solicited local AEs for the duration of the study. Fever, malaise, headache, and diarrhea were solicited systemic AEs for the first seven days following each vaccination; events reported outside this time frame were considered non-solicited.

Secondary Outcome Measures

Characterization and Comparison of Group LT-specific Immune Responses to the TD Vaccine System: Geometric Mean Titers
LT immunoglobulin G (IgG) and immunoglobulin A (IgA)
Characterization and Comparison of Group LT-specific Immune Responses to the TD Vaccine System: Geometric Mean Fold Ratios
LT immunoglobulin G (IgG) and immunoglobulin A (IgA)
Characterization and Comparison of Group LT-specific Immune Responses to the TD Vaccine System: Seroconversion Rates
LT immunoglobulin G (IgG) and immunoglobulin A (IgA)
