About this study

Official title: Immunogenicity and Safety of Three Consecutive Lots of a New Inactivated Enterovirus Type 71 (EV71) Vaccine: A Double-blind, Randomized and Controlled Trial

The purpose of this study is to evaluate the immunogenicity and safety of three consecutive lots of EV71 Vaccines in healthy infants volunteers aged from 6 months to 5 years old.

Read the detailed description

The data from the phase I and II study suggested that the inactivated EV71 vaccine (vero cell) had a clinically acceptable safety and good immunogenicity for healthy Chinese infants. The phase III study of inactivated vaccine has initiated on Jan 2012 in China. Over 10,000 healthy infants have revieved the vaccines and no unexpected severe adverse reactions were reported. According to the requirement of SFDA (China), the sponsor should also provide the evidence for the consistency of three consecutive lots of EV71 Vaccines before the application for the market. Thus, a clinical trial to evaluate the immunogenicity and safety of three consecutive lots of EV71 Vaccines in healthy infants volunteers is planed to conduct.

Being tested
three consecutive lots of EV71 vaccine, placebo

What is being measured

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

  1. The GMT of anti-EV71 antibodies in serum 28 days after the two-dose regimen

    to evaluate the immunogenicity of anti-EV71 antibodies in serum 28 days after second vaccination

    Measured: 28 days after first vaccination

Secondary outcomes (2)
  1. Frequency of systemic and local adverse reactions after the first vaccination

    Frequency of systemic and local adverse reactions in healthy infants following first doses of EV71 vaccine

    Measured: 28 days after the first vaccination

  2. Frequency of systemic and local adverse reactions after the second vaccination

    Frequency of systemic and local adverse reactions in healthy infants following second doses of EV71 vaccine

    Measured: 28 days after the second vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing three consecutive lots of EV71 vaccine in people with Hand, Foot and Mouth Disease, run by Sinovac Biotech Co., Ltd 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 3 inclusion and 18 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 15 Mar 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 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. Some participants in this study may receive a placebo. 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?

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?

The GMT of anti-EV71 antibodies in serum 28 days after the two-dose regimen (time frame: 28 days after first vaccination). 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 NCT01636245, which also lists 2 linked publications.

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 15 Mar 2013.
