E.5 End points |
E.5.1 | Primary end point(s) |
Percentage of subjects developing at least a four-fold rise in their antibody titers between the pre-booster (Visit 1) and one month (4-6 weeks [28-42 days]) after the dose of IPV (Visit 2). |
|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Pre-booster (Visit 1) and 1 post-IPV dose (Visit 2) |
|
E.5.2 | Secondary end point(s) |
Immunogenicity 1) Before (Visit 1) and one month (4-6 weeks [28-42 days]) after the dose of IPV (at Visit 2): - % of subjects with anti-polio 1, 2 and 3 antibody titers ≥8 (1/dil) - Geometric Mean of Titers (GMT) against polio 1, 2 and 3 - Geometric Mean of individual Titer Ratio (GMTR) against polio 1, 2 and 3 between pre- and post-booster time points
Safety The secondary endpoints for the safety evaluation were: 1) Occurrence, intensity, and relationship to vaccination of any unsolicited systemic AEs reported within 30 minutes after vaccination. 2) Occurrence, time to onset, number of days of occurrence, and intensity of solicited injection-site and systemic reactions (terms prelisted in the subject’s diary card and eCRF) occurring from Day 0 to Day 7 after vaccination. 3) Occurrence, nature (MedDRA preferred term), maximum intensity (for non-serious AEs only), and relationship to vaccination (for systemic AEs only) of unsolicited AEs up to 28 days after vaccination. 4) Occurrence of any SAE regardless of the relationship to the vaccination(s) throughout the trial from Visit 1 to Visit 2. |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
Immunogenicity 1) Pre-dose (Visit 1) and 1 month post-IPV dose (Visit 2)
Safety 1) Within 30 minutes of vaccination 2) Day 0 up to Day 7 post-vaccination 3) Day 0 up to Day 28 post-vaccination 4) Day 0 up to Day 28 post-vaccination |
