Trial Outcomes & Findings for Assessment of the Immunogenicity and Safety of a Dose-Sparing BioThrax® AVA Schedule (NCT NCT01641991)

NCT ID: NCT01641991

Last Updated: 2014-05-28

Results Overview

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the toxin neutralization antibody assay to determine the NF50 antibody titer. A participant met the threshold of a 4-fold rise in NF50 antibody titer if the post vaccination titer was an increase by 4-fold or more from the baseline (Day 0) titer.

PRIMARY outcome

Timeframe: Days 0, 7, 14, 21, 28 35, 42, 49, 56, 63, 70, 84 and 100

Population: The per protocol analysis population includes participants who met all inclusion and exclusion criteria, received all doses in the primary series, completed all scheduled visits up to and including the Day 100 visit in-window, and who contributed both pre- and post-vaccination blood samples for testing for which valid results were reported.

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the toxin neutralization antibody assay to determine the NF50 antibody titer. A participant met the threshold of a 4-fold rise in NF50 antibody titer if the post vaccination titer was an increase by 4-fold or more from the baseline (Day 0) titer.

SECONDARY outcome

Timeframe: Days 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 84 and 100.

Population: The per protocol analysis population includes participants who met all inclusion and exclusion criteria, received all doses in the primary series, completed all scheduled visits up to and including the Day 100 visit in-window, and who contributed both pre- and post-vaccination blood samples for testing for which valid results were reported.

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the ELISA assay to determine the anti-PA IgG antibody concentration. The geometric mean of subjects' visit-specific titers were calculated along with the 95% confidence intervals. If the antibody titer was below the lower limit of quantification (LLOQ) for the assay, half the value of LLOQ (4.64) was imputed. When all subjects' titers were below LLOQ resulting in no variability within the group, the 95% CI was not calculated.

SECONDARY outcome

Timeframe: Days 0-7 after vaccination at Day 0

Population: The analysis population includes all participants who were vaccinated at Day 0 per protocol, excluding 59 participants at one clinic site who were vaccinated in the fatty tissue over the triceps rather than the intended inferior deltoid.

Participants maintained a memory aid to record daily the occurrence of local reactions for 8 days after vaccination based on their interference with daily activities (pain, itchiness, warmth, and tenderness at injection site, arm motion limitation) or based on a quantitative measurement of the reaction (edema, erythema). In the subjective grading scale, severe reactions prevented daily activities, moderate reactions interfered with but did not prevent daily activities, and mild reactions did not interfere with daily activities. For the quantitative scale, severe reactions greater than 100 millimeters (mm), moderate reactions were 51-100 mm, and mild reactions were 25-50 mm. Participants are counted by the maximum severity they reported experiencing the reaction on any of the 8 days.

SECONDARY outcome

Timeframe: Days 0-7 after vaccination at Day 14

Population: The analysis population includes all participants who were vaccinated at Day 14 per protocol, excluding 59 participants at one clinic site who were vaccinated in the fatty tissue over the triceps rather than the intended inferior deltoid.

Participants maintained a memory aid to record daily the occurrence of local reactions for 8 days after vaccination based on their interference with daily activities (pain, itchiness, warmth, and tenderness at injection site, arm motion limitation) or based on a quantitative measurement of the reaction (edema, erythema). In the subjective grading scale, severe reactions prevented daily activities, moderate reactions interfered with but did not prevent daily activities, and mild reactions did not interfere with daily activities. For the quantitative scale, severe reactions greater than 100 millimeters (mm), moderate reactions were 51-100 mm, and mild reactions were 25-50 mm. Participants are counted by the maximum severity they reported experiencing the reaction on any of the 8 days.

SECONDARY outcome

Timeframe: Days 0-7 after each vaccination

Population: The analysis population includes all participants who were vaccinated per protocol, excluding 59 participants at one clinic site who were vaccinated in the fatty tissue over the triceps rather than the intended inferior deltoid.

Participants were given a ruler with the memory aid to measure the occurrence of edema (swelling) and erythema (redness) daily for at least 8 days after each vaccination. Participants are counted in this outcome measure if they had measurements of greater than 120 mm in the 8-day period after at least one vaccination, first separately for edema and erythema, and in the last category, edema and/or erythema, if they had either or both reactions of greater than 120 mm.

SECONDARY outcome

Timeframe: Days 0, 7, 14, 21, 28, 35, 42, 49, 56, 63, 70, 84 and 100.

Population: The per protocol analysis population includes participants who met all inclusion and exclusion criteria, received all doses in the primary series, completed all scheduled visits up to and including the Day 100 visit in-window, and who contributed both pre- and post-vaccination blood samples for testing for which valid results were reported.

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the toxin neutralization antibody assay to determine the NF50 antibody titer. The geometric mean of subjects' visit-specific titers were calculated along with the 95% confidence intervals. If the antibody titer was below the lower limit of quantification (LLOQ) for the assay, half the value of LLOQ (0.03) was imputed. When all subjects' titers were below LLOQ resulting in no variability within the group, the 95% CI was not calculated.

SECONDARY outcome

Timeframe: Day 7 through Day 100

Population: The per protocol analysis population includes participants who met all inclusion and exclusion criteria, received all doses in the primary series, completed all scheduled visits up to and including the Day 100 visit in-window, and who contributed both pre- and post-vaccination blood samples for testing for which valid results were reported.

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the ELISA assay to determine the anti-PA IgG antibody concentration. To determine the group peak GMC, the highest antibody concentration assessed for each subject at any post vaccination visit through Day 100 was determined. The geometric mean of subjects' peak concentrations was calculated along with the 95% confidence intervals.

Timeframe: Days 0-7 after vaccination at Day 0

Population: The analysis population includes all participants who were vaccinated at Day 0 per protocol, excluding 59 participants at one clinic site who were vaccinated in the fatty tissue over the triceps rather than the intended inferior deltoid.

Participants maintained a memory aid to record daily the occurrence of solicited systemic reactions of fatigue, muscle aches, and headache for 8 days after vaccination based on their interference with daily activities. Severe reactions prevented daily activities, moderate reactions interfered with but did not prevent daily activities, and mild reactions did not interfere with daily activities. Participants are counted by the maximum severity they reported experiencing the reaction on any of the 8 days.

SECONDARY outcome

Timeframe: Day 7 through Day 100

Population: The per protocol analysis population includes participants who met all inclusion and exclusion criteria, received all doses in the primary series, completed all scheduled visits up to and including the Day 100 visit in-window, and who contributed both pre- and post-vaccination blood samples for testing for which valid results were reported.

Blood was collected from all participants prior to vaccination and at scheduled follow up visits weekly through Day 70, at Day 84 and at Day 100 for testing in the toxin neutralization antibody assay to determine the NF50 antibody titer. To determine the group peak GMT, the highest titer assessed for each subject at any post vaccination visit through Day 100 was determined. The geometric mean of each subjects' peak titers was calculated along with the 95% confidence intervals.
