About this study

Official title: Effectiveness of PCV7 in the Prevention of Nasopharyngeal Carriage of Vaccine Serotype (VT) Streptococcus Pneumoniae in 2 to 5 Years Old Healthy Chinese Children.

A parallel-group, randomized, open-label study will be performed in subjects receiving PCV7 and subjects receiving controlled vaccine Hib vaccine, to claim the efficacy of PCV7 in the prevention of NP carriage of vaccine-serotype S. pneumoniae (serotypes 4, 6B, 9V, 14, 18C, 19F, and 23F combined) in 2 to 5 years old healthy Chinese children.

Read the detailed description

In 2005, clinical trials with PCV7 (Prevenar) were first conducted in China. In the phase 3 study involving Chinese infants, Prevenar was shown to be immunogenic, well tolerated, and safe when given either separately or concomitantly with a diphtheria, tetanus, and acellular pertussis (DTaP) vaccine at 3, 4, and 5 months of age. Controlled clinical trials elsewhere in the world showed the correlation between immunogenicity and disease prevention. In addition to the direct effect of Prevenar, immunization of children has also reduced the incidence of disease in adults. The changes are presumed to be due to reductions in nasopharyngeal carriage of vaccine serotype S. pneumoniae in children who have been vaccinated.

The purpose of this study will be to assess the effectiveness of Prevenar vaccination to reduce vaccine serotype (VT) NPC rates in Chinese children aged 2 to 5 years old.

What is being measured

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

  1. Carriage Rate of Vaccine-Serotype S. pneumoniae at 180days after vaccination

    Measured: 6 months

Secondary outcomes (10)
  1. Carriage Rate of vaccine-serotype S. pneumoniae in PCV7 group versus Hib group.

    Measured: 60 days

  2. Carriage rate of non-vaccine serotype S. pneumoniae in PCV7 group versus Hib group.

    Measured: Baseline before vaccination

  3. Carriage rate of non-vaccine serotype S. pneumoniae in PCV7 group versus Hib group.

    Measured: 60 days after vaccination

  4. Carriage rate of non-vaccine serotype S. pneumoniae in PCV7 group versus Hib group.

    Measured: 6 months after vaccination

  5. Carriage rate of individual serotype S. pneumoniae in PCV7 group and Hib group.

    Measured: Baseline before vaccination

  6. Carriage rate of individual serotype S. pneumoniae in PCV7 group and Hib group.

    Measured: 60 days after vaccination

  7. Carriage rates of individual serotype S. pneumoniae in PCV7 group and Hib group.

    Measured: 6 months after vaccination

  8. Carriage rate of antibiotic resistant S. pneumoniae as a group in PCV7 group and Hib group.

    Measured: 6 months after vaccination

  9. Percentage of adverse event related to vaccination in PVC7 group and Hib group.

    Measured: 6 months after vaccination

  10. Category of adverse event related to vaccination in PVC7 group and Hib group.

    Adverse effects are classified as referenced from the China Food and Drug Administration's "Preventive Vaccines Clinical Study Adverse Effects Assessment Standards". This evaluation of systemic reactions is partially based on standards for classification set by the United States National Institutes of Health and the National Institute of Allergy and Infectious Diseases.

    Measured: 6 months after vaccination

Questions about this trial

What is this clinical trial studying?

A study testing PCV7 (Pneumococcal 7-Valent Conjugate Vaccine) and Hib Vaccine in people with Streptococcal Pneumonia and Nasopharyngeal Diseases, run by Centers for Disease Control and Prevention, China at 9 sites 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 5 inclusion and 14 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 20 May 2016. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites 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.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Carriage Rate of Vaccine-Serotype S. pneumoniae at 180days after vaccination (time frame: 6 months). 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 20 May 2016.
