Measured: Day 0 (pre-booster) and Day 30 post-booster

Secondary outcomes (1)

Number of Participants Reporting at Least One Solicited Injection Site or Systemic Reaction Post-booster Vaccination With PENTAXIM™
Solicited Injection Site Reactions: Pain, Erythema, Swelling. Solicited Systemic Reactions: Pyrexia (Temperature), Vomiting, Crying, Somnolence, Anorexia, Irritability.
Grade 3 was defined as: Pain, cries when injected limb is moved or movement of limb is reduced; Erythema and Swelling, ≥ 5 cm; Pyrexia, ≥ 39.6ºC; Vomiting, ≥ 6 episodes/24 hour or requiring parenteral hydration; Crying, > 3 hours; Somnolence, sleeping most of the time or difficulty to wake up; Anorexia, refuses ≥ 3 feeds/meals or refuses most feeds/meals; and Irritability, inconsolable.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing DTaP-IPV//PRP~T combined vaccine in people with Diphtheria and Tetanus, run by Sanofi at 1 site in Argentina.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 22 Feb 2013. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Argentina. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Feb 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Summary of Antibody Persistence at 18 Months of Age in Participants That Received Primary Series Vaccination of Either DTaP-IPV-HepB-PRP~T or PENTAXIM™ and ENGERIX B® PEDIATRICO at 2, 4, and 6 Months of Age. (time frame: Day 0 (Before booster vaccination)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00303316, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Feb 2013; AzTrials last refreshed its copy on 8 Nov 2026.
