NCT ID: NCT03518125
Last Updated: 2020-07-21
Results Overview
Count of participants who experienced at least one of the following during the time frame specified on the arm which received the vaccination: injection site warmth, tenderness, itching, pain, restriction of range of arm motion, erythema/redness, palpable or observable lump, induration/swelling, or bruising.
COMPLETED
PHASE2
305 participants
Day 1-8, Day 15-22, Day 29-36 (within 8 days of each vaccination, inclusive of the vaccination day)
2020-07-21
Participant Flow
469 participants were screened at 4 sites in the US between May 14, 2018 - November 8, 2018, of which 305 were randomized and vaccinated between May 17, 2018 - November 12, 2018.

Timeframe: Day 64Population: Immunogenicity per protocol population (IPPP) includes all randomized participants who received a full dose of the correct vaccine at Days 1, 15, and 29 within the protocol specified windows, had determinate assay results at Day 64 (within window), and had no major protocol deviations that may have impacted immunogenicity assessments.
The percentage of participants achieving seroprotection based on TNA NF50. A 70% probability of survival was associated with a TNA NF50 level of 0.56 in rabbits exposed to Bacillus anthracis, the bacteria that causes anthrax.

SECONDARY outcome
Timeframe: Days 1, 8, 22, 29, 36, 43, 50, 85, 181, and 394Population: Immunogenicity per protocol population (IPPP) includes all randomized participants who received a full dose of the correct vaccine at Days 1, 15, and 29 within the protocol specified windows, had determinate assay results at Day 64 (within window), and had no major protocol deviations that may have impacted immunogenicity assessments.
The percentage of participants achieving seroprotection based on TNA NF50 antibody level. A 70% probability of survival was associated with a TNA NF50 level of 0.56 in rabbits exposed to Bacillus anthracis, the bacteria that causes anthrax.
