E.5 End points |
E.5.1 | Primary end point(s) |
Primary endpoint
Ratio of GMCs (GMC liquid formulation / GMC lyophilized formulation) for each serotype-specific (Ia, Ib, and III) GBS antibody concentration by study group at Day 31.
Safety Endpoints
-Percentage and frequency of subjects with solicited local and solicited systemic AEs reported up to Day 7 and calculated for four time intervals after Day 1 vaccination: 30 minutes, Days 1-3 (without 30 min), Days 4-7 (without 30 min), Days 1-7 (without 30 min).
-Frequency and percentages of subjects with any unsolicited AEs reported for Day 1 to Day 31.
-Frequency and percentages of subjects with AEs leading to non-routine medical visit or emergency room visit, and AEs leading to study withdrawal, and concomitant medications associated with these events as reported for Day 1 to Day 31.
Frequency and percentages of subjects with AEs leading to non-routine medical visit or emergency room visit, and AEs leading to study withdrawal, and concomitant medications associated with these events as reported for Day 31 to Day 181 (study termination).
-Frequency and percentages of subjects with SAEs, and concomitant medications associated with these events as reported for Day 1 to Day 181 (study termination). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
A planned interim safety and immunogenicity analysis may be performed when data up to Day 31 after vaccination for all subjects become available in order to facilitate formulation selection for a planned phase III study. The primary objective of the study will be assessed at that time together with safety analyses carried out on data up to that time point.
Evaluation of this endpoint may also be undertaken at the end of the study. |
