Study summary

This study aims to assess and confirm the adequate immunogenicity and safety profile of the Sanofi Pasteur's DTaP-Hep B-IPV-PRP-T fully liquid combined hexavalent vaccine administered in HIV-exposed uninfected infants and in HIV-exposed infected infants.

The primary objectives of the study are:

  • To evaluate the immunogenicity of the study vaccine 1 month after the 3-dose primary series in HIV-exposed infected and in HIV-exposed uninfected infants.
  • To describe the persistence of all antibodies before receipt of the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants.
  • To evaluate the immunogenicity of the study vaccine 1 month after the booster dose in HIV-exposed infected and in HIV-exposed uninfected infants.

The secondary objectives of the study are:

  • To describe the safety profile after each and all doses of the study vaccine administered as a 3-dose infant primary series in HIV-exposed infected and in HIV-exposed uninfected infants.
  • To describe the safety profile of the study vaccine administered as a booster in HIV-exposed infected and in HIV-exposed uninfected infants.
Read the detailed description

Male and female infants born from HIV-infected mothers will be tested for HIV infection from birth to 6 weeks of age. HIV infected and HIV uninfected participants will be enrolled into two groups at Day 0. Some infants detected HIV-exposed infected outside of the hospital center facilities and the trial screening procedure may also be enrolled. All participants will receive primary vaccinations with Sanofi Pasteur's DTaP-IPV-HB-PRP-T combined vaccine at 6, 10 and 14 weeks of age and a booster dose at approximately 15 to 18 months of age will receive a booster dose of the Sanofi Pasteur's DTaP-IPV-HB-PRP-T combined vaccine.

Secondary outcomes

  1. Number of Participants With Immediate Unsolicited Adverse Events (AE) After Primary Series Vaccination

    An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the electronic case report form (eCRF) in terms of diagnosis and/or onset post-vaccination.

    Time frame: Within 30 minutes after vaccination

  2. Number of Participants With Solicited Injections Site or Systemic Reactions After Primary Series Vaccination

    A solicited reaction is an adverse reaction observed and reported under the conditions (symptom and onset) prelisted (i.e., solicited) in the eCRF and considered as related to vaccination. Solicited injection site reactions: injection site tenderness, erythema, and swelling. Solicited systemic reactions: fever, vomiting, crying abnormal, drowsiness, appetite lost, and irritability

    Time frame: Within 7 days after vaccination

  3. Number of Participants With Unsolicited Adverse Events After Primary Series Vaccination

    An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of diagnosis and/or onset post-vaccination. An unsolicited non-serious AE is an unsolicited AE excluding serious adverse events (SAEs). Systemic AEs are all AEs that are not injection site reactions. They therefore include systemic manifestations such as headache, fever, as well as localized or topical manifestations that are not associated with the vaccination site.

    Time frame: Within 30 days after vaccination

  4. Number of Participants With Serious Adverse Events During the Study

    An SAE is any untoward medical occurrence that at any dose results in death, is life-threatening, requires inpatient hospitalisation or prolongation of existing hospitalisation, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is an important medical event.

    Time frame: Day 0 to Day 420

  5. Number of Participants With Immediate Unsolicited Adverse Events After Booster Vaccination

    An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of diagnosis and/or onset post-vaccination.

    Time frame: Within 30 minutes after booster vaccination

  6. Number of Participants With Solicited Injection Site or Systemic Reactions After Booster Vaccination

    A solicited reaction is an adverse reaction observed and reported under the conditions (symptom and onset) prelisted (i.e., solicited) in the eCRF and considered as related to vaccination. Solicited injection site reactions: tenderness, erythema, swelling, and extensive limb swelling. Solicited systemic reactions: fever, vomiting, crying abnormal, drowsiness, appetite lost, and irritability.

    Time frame: Within 7 days after booster vaccination

  7. Number of Participants With Unsolicited Adverse Events After Booster Vaccination

    An unsolicited AE is an observed AE that does not fulfill the conditions prelisted in the eCRF in terms of diagnosis and/or onset post-vaccination. An unsolicited non-serious AE is an unsolicited AE excluding SAEs. Systemic AEs are all AEs that are not injection site reactions. They therefore include systemic manifestations such as headache, fever, as well as localized or topical manifestations that are not associated with the vaccination site.

    Time frame: Within 30 days after booster vaccination

Ran from Jul 2016 to primary completion in Feb 2019, 31 months.

Of 37 industry-sponsored phase 3 interventional studies under Diphtheria, half reached primary completion within 12 months of starting (the median), counting those still running; a quarter within 7 and three quarters within 25. This study's 31 months is above that.

Counting every sponsor, half of 37 studies reached it within 12 months; a quarter within 7 and three quarters within 25.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
