Primary Outcome Measures:
  • Number of Participants With Wild Type-4 Febrile Adenovirus (ADV) Acute Respiratory Disease (ARD) -- ITT Cohort [ Time Frame: Day 0 - Day 56 ]
    For the oral Type-4 vaccine, the primary outcome is the number of cases of ADV-4 febrile acute respiratory disease (ARD), defined as a subject with one or more clinical signs and symptoms of ARD and an oral temperature ≥ 100.5°F (38.06°C) and throat culture positive for wild ADV Type-4 infection. This outcome used the intent-to-treat cohort.

  • Number of Participants With Wild Type-4 Febrile Adenovirus (ADV) Acute Respiratory Disease (ARD) -- PP Cohort [ Time Frame: Day 0 - Day 56 ]
    For the oral Type-4 vaccine, the primary outcome is the number of cases of ADV-4 febrile acute respiratory disease (ARD), defined as a subject with one or more clinical signs and symptoms of ARD and an oral temperature ≥ 100.5°F (38.06°C) and throat culture positive for wild ADV Type-4 infection. This outcome used the per protocol cohort.

  • Number of Participants With Wild Type-4 Febrile Adenovirus (ADV) Acute Respiratory Disease (ARD) -- ITT Cohort --- Day 11-56 [ Time Frame: Day 11 - Day 56 ]
    For the oral Type-4 vaccine, the primary outcome is the number of cases of ADV-4 febrile acute respiratory disease (ARD), defined as a subject with one or more clinical signs and symptoms of ARD and an oral temperature ≥ 100.5°F (38.06°C) and throat culture positive for wild ADV Type-4 infection. This outcome used the intent-to-treat cohort; further, this outcome omitted ARD cases from Day 0-Day 10 because the protective effect of the vaccine was unlikely to take place during that time period.

  • Percentage of Participants Showing ADV-7 Seroconversion at Week 4 [ Time Frame: Week 4 ]
    ADV-7 seroconversion was defined as the development of ADV Type-7 neutralizing antibody at Week 4 (Day 26) after study medication that represented at least a fourfold increase in titer from baseline (visit 0) in a subject whose baseline Type-7 titer was <1:4.


Secondary Outcome Measures:
  • Percentage of Participants Showing ADV-4 Seroconversion at Week 4 [ Time Frame: Week 4 ]
    ADV-4 seroconversion was defined as the development of ADV Type-4 neutralizing antibody at Week 4 (Day 26) after study medication that represented at least a fourfold increase in titer from baseline (visit 0) in a subject whose baseline Type-4 titer was <1:4.

  • Number of Participants With Wild Type-4 Adenovirus (ADV) Acute Respiratory Disease (ARD) -- ITT Cohort [ Time Frame: Day 0 - Day 56 ]
    For the oral Type-4 vaccine, the number of cases of ADV-4 acute respiratory disease (ARD) regardless of whether the participant was febrile or not. Therefore includes participants with one or more clinical signs and symptoms of ARD and throat culture positive for wild ADV Type-4 infection. This outcome used the intent-to-treat cohort.

  • Percentage of Participants Showing ADV Type-4 Booster at Week 4 [ Time Frame: Baseline, Week 4 ]
    ADV-4 booster effect is defined as the development of ADV Type-4 neutralizing antibody at Week 4 (Day 26) that represented at least a fourfold increase in titer from baseline (Visit 0) in a participant whose baseline Type-4 titer is ≥1:4.

  • Number of Participants With Wild Type-7 Febrile Adenovirus (ADV) Acute Respiratory Disease (ARD) -- ITT Cohort [ Time Frame: Day 0 - Day 56 ]
    For the oral Type-7 vaccine, a secondary outcome is the number of cases of ADV-7 febrile acute respiratory disease (ARD), defined as a subject with one or more clinical signs and symptoms of ARD and an oral temperature ≥ 100.5°F (38.06°C) and throat culture positive for wild ADV Type-7 infection. This outcome used the intent-to-treat cohort.

  • Number of Participants With Wild Type-7 Adenovirus (ADV) Acute Respiratory Disease (ARD) -- ITT Cohort [ Time Frame: Day 0 - Day 56 ]
    For the oral Type-7 vaccine, the number of cases of ADV-7 acute respiratory disease (ARD) regardless of whether the participant was febrile or not. Therefore includes participants with one or more clinical signs and symptoms of ARD and throat culture positive for wild ADV Type-7 infection. This outcome used the intent-to-treat cohort.

  • Percentage of Participants Showing ADV Type-7 Booster at Week 4 [ Time Frame: Baseline, Week 4 ]
    ADV-7 booster effect is defined as the development of ADV Type-7 neutralizing antibody at Week 4 (Day 26) that represented at least a fourfold increase in titer from baseline (Visit 0) in a participant whose baseline Type-7 titer is ≥1:4.

Primary Completion Date: December 2007 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vaccine
Participants received a single tablet of both Type-4 and Type-7 adenovirus vaccines at study visit 1 (Day 0).
Biological: DR-5001
All randomized subjects received a single tablet of both Type-4 and Type-7 ADV vaccines on Day 0. Both vaccine tablets were administered orally, kept in the mouth as briefly as possible and swallowed whole with water. Chewing the tablets was not permitted.
Placebo Comparator: Placebo
Participants received a single tablet of both placebos that matched the Type-4 and Type-7 adenovirus vaccines at study visit 1 (Day 0).
Other: Placebo
All randomized subjects received a single tablet each of the placebos matching Type-4 and Type-7 ADV vaccines on Day 0. Both placebo tablets were administered orally, kept in the mouth as briefly as possible and swallowed whole with water. Chewing the tablets was not permitted.

Detailed Description:
The study will be conducted at two sites and will include a minimum of 4 visits. The overall study duration for participants will be approximately 8 weeks. Study participants will undergo acute respiratory disease evaluation that will include a throat swab and a blood draw. Each participant will also be contacted in six months for follow-up information.
