Study groupRoleWhat they receive
Hib CRM197ExperimentalSubjects treated with 3 doses of CRM 197 -conjugate Haemophilus influenzae type b vaccine (study vaccine): 2 doses given one month apart during study V37_07 (NCT01044316) and a booster dose of the same vaccine six months after, during study V37_07E1 (NCT01226953). No vaccine was administered during this trial

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Geometric Mean Anti-PRP (Polyribosyl Ribitol Phosphate) Concentrations at Day 1 (4 Years Post Booster Dose Administered in Study V37_07E1)

    Immunogenicity was measured as geometric mean of Anti- PRP Concentrations, approximately 4 years after booster vaccination with either Hib-CRM197 or Hib-TT in children participating in previous V37_07E1 trial.

    Measured: At Day 1 (4 years post booster dose administered in study V37_07E1)

Secondary outcomes (1)
  1. Percentages of Subjects With Anti-PRP Concentrations ≥1.0 μg/mL and ≥0.15 μg/mL at Day 1 (4 Years Post Booster Dose Administered in Study V37_07E1)

    Immunogenicity was measured as the percentages of subjects with Anti-PRP Concentrations ≥1.0 μg/mL and ≥0.15 μg/mL approximately 4 years after booster vaccination with either Hib-CRM197 or Hib-TT in V37_07E1 trial.

    Measured: At Day 1 (4 years post booster dose administered in study V37_07E1)

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Hib-CRM197 and Hib-TT in people with Meningitis, Epiglottitis, Pneumonia, Arthritis Caused by Haemophilus Influenzae Type b, run by Novartis Vaccines at 1 site in China.

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 2 inclusion and 6 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 9 Nov 2015. 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 China. 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 9 Nov 2015). 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?

Geometric Mean Anti-PRP (Polyribosyl Ribitol Phosphate) Concentrations at Day 1 (4 Years Post Booster Dose Administered in Study V37_07E1) (time frame: At Day 1 (4 years post booster dose administered in study V37_07E1)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Nov 2015.
