| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To demonstrate that DTaP-IPV-Hep B-PRP-T combined vaccine + OPV placebo does not induce a higher incidence rate of high fever than Tritanrix-Hep B/Hib™ + OPV after any of the three vaccinations at 2, 4, and 6 months of age for each subject. |
|
| E.2.2 | Secondary objectives of the trial |
Safety
To evaluate the overall safety profile of DTaP-IPV-Hep B-PRP-T vaccine in terms of:
• Any solicited adverse reactions (ARs) in the first 7 days after each injection
• Any adverse events (AE) and ARs in the first 30 days after each injection*
• Any SAEs during the trial
* including any unsolicited AEs occurring in the first 30 minutes after each vaccination
Immunogenicity
To document the immune response to Hep B antigen of the three batches of the investigational DTaP-IPV-Hep B-PRP-T vaccine and the Tritanrix-Hep B/Hib™ + OPV control vaccine. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
1) Two-month-old infants (50 to 71 days old inclusive) on the day of inclusion
2) Born at full term of pregnancy (≥37 weeks) with a birth weight ≥2.5 kg
3) Informed Consent Form signed by one or both parents, or by a legally acceptable representative, and one or two independent witnesses. (In Peru, parents/legally acceptable representatives' finger print and an independent witness' signature were required if the parents/legally acceptable representative was illiterate)
4) Able to attend all scheduled visits and to comply with all trial procedures
5) Had complied with the national immunization calendar (Bacille Calmette-Guérin [BCG] for both countries) for the first 2 months of life (e.g. Mexico: no dose of Hep B vaccine since birth; Peru: one dose of Hep B vaccine at birth) |
|
| E.4 | Principal exclusion criteria |
1) Participation in another clinical trial in the 4 weeks preceding the first trial vaccination
2) Planned participation in another clinical trial during the present trial period
3) Congenital or acquired immunodeficiency, or immunosuppressive therapy such as long-term systemic corticosteroids therapy
4) Subjects with congenital or acquired immunodeficiency in the child's surroundings
5) Systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the trial vaccine or a vaccine containing the same substances
6) Chronic illness at a stage that could have interfered with trial conduct or completion
7) Blood or blood-derived products received since birth
8) Any vaccination in the 4 weeks preceding the first trial vaccination
9) Vaccination planned in the 4 weeks following the trial vaccination
10) Documented history of pertussis, T, D, poliomyelitis (polio), Hib, or Hep B infection(s) (confirmed either clinically, serologically, or microbiologically)
11) Mother known as seropositive for human immunodeficiency virus or hepatitis C, or known carrier of HBs Ag
12) Previous vaccination against pertussis, T, D, polio, or Hib infection(s)
13) Coagulopathy, thrombocytopenia, or a bleeding disorder contraindicating IM vaccination
14) History of seizures
15) Febrile (rectal equivalent temperature ≥38.0°C) or acute illness on the day of inclusion |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| Occurrence of at least one high fever episode (≥39.6°C rectal temperature equivalent) observed within 7 days after any of the three injections for each subject. |
|
| E.5.1.1 | Timepoint(s) of evaluation of this end point |
| Daily follow-up of rectal temperature (in the morning and in the evening) was carried out for 7 days after each vaccination. |
|
| E.5.2 | Secondary end point(s) |
Safety :
• Occurrence, time to onset, duration, and severity for any unsolicited AE reported in the 30 minutes after each vaccination
• Occurrence, time to onset, number of days of occurrence, severity, action taken, and seriousness of solicited (pre-listed in the subject diary card and Case Report Form) injection site reactions (tenderness, erythema, and swelling) and systemic reactions (fever, vomiting, crying abnormal, drowsiness, appetite lost, and irritability) occurring up to 7 days after each vaccination
• Occurrence, nature (Medical Dictionary for Regulatory Activities preferred term), system organ class, time to onset, duration, severity, action taken, relationship to vaccination (for unsolicited systemic events only), and seriousness of unsolicited (spontaneously reported) AEs up to 30 days after each vaccination and of SAEs throughout the trial up to 6 months after the last vaccination
Immunogenicity
• Anti-hepatitis B surface (HBs) antibody titers and seroprotection (anti-HBs ≥10 mIU/mL and ≥100 mIU/mL) at Day 150 (30 days after last vaccination)
• Descriptive analysis of the three batches of DTaP-IPV-Hep B-PRP-T vaccine and the geometric mean titer (GMT) at Day 150 |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
For site 001 (Mexico), one blood sample (3 mL) was drawn 1 month after the third vaccination (Visit [V] 06) for the subjects participating to the immunogenicity analysis subset (planned:306, actual: 287).
A phone call or a visit was arranged to collect information on any SAE occurring during the 6 months after the last vaccine administration. |
