Study Endpoints

Primary Endpoints

Geometric Mean Ratio (GMR) at Day 11 for Vaccine Lots A and B
Day 11

The primary analysis consisted of three between-lot equivalence tests of serum vibriocidal antibody titer measured at Day 11. The GMT of each lot - µA, µB, and µC - was calculated by first log-transforming (base 10) the serum vibriocidal antibody titers, computing the means of the transformed data by lot, and then exponentiating the log-scale means to return to the original, untransformed scale. The resulting GMTs were combined to form three geometric mean ratios: µA/µB, µA/µC, and µB/µC.The ratios were required to be within +/- 50% of each other lot with 95% confidence, which implied that the limits of the 95% confidence interval on each pairwise GMR had to be within 0.67 - 1.5. Placebo GMT values were not included in the primary analysis.
