简要总结
The objective is to demonstrate equivalence of three IC51 batches in terms of Geometric Mean Titers for anti-JEV neutralizing antibody.
详细描述
This is a randomized, controlled, multi-center, double blind phase 3 study. The study population consists of male and female healthy subjects, aged at least 18 years.
624 subjects will be enrolled at approximately 6 sites in study centers in Austria and Germany.

结局指标
主要结局
GMT for Anti-JEV Neutralizing Antibody
时间窗: day 56
Equivalence between batches with regards to GMT (Geometric Mean Titer) was postulated if all three pair-wise 95 % Confidence Intervals for GMT ratios were between 0.5 and 2.
次要结局
- SCR for Anti-JEC Neutralizing Antibody Titer(day 56)
- Safety(study duration)
