About this study

Official title: The Safety and Immunogenicity of Enterovirus Type 71 Inactivated Vaccine (Human Diploid Cell) With Two Measles Attenuated Live Vaccine and Live Attenuated Japanese Encephalitis Vaccine at the Same Time Point in Infants (8-month-old)

Enterovirus 71 (EV71), a major pathogen causing hand-foot-and-mouth disease (HFMD) worldwide, is a member of the Human Enterovirus species A, family Picornaviridae. Its infection occasionally leads to severe diseases and death, with central nervous system (CNS) damage.

Recently, except of inactivated vaccine, several EV71 vaccine candidates have been evaluated in animals but no final results of clinical trials, such as attenuated vaccine, subunit vaccine. A formalin-inactivated EV71 vaccine (Human Diploid cell, KMB-17 Cell) has been finished phase I, II and III clinical trials and licensed by SFDA in China at Dec. 3, 2015. Based on the results of clinical trials, the protective efficacy of inactivated EV71 vaccine is 97% against HFMD caused by EV71. The phase IV clinical trial has been carried out from July 2016. The purpose of phase IVd is to evaluated the immunogenicity and safety of the inactive EV71 vaccine within two measles attenuated live vaccine and live attenuated Japanese encephalitis vaccine at the same time point in large scale population of Chinese children (8 months old) in Guangdong Province, China.

Read the detailed description

There are two parts of phase IVd clinical trials have been performed. First, to evaluate the immunogenicity of the inactive EV71 vaccine within two measles attenuated live vaccine and live attenuated Japanese encephalitis vaccine at the same time point in large scale population of Chinese children (8 months old), within 56-day-post-immunized.

Second, to safety of the inactive EV71 vaccine within two measles attenuated live vaccine and live attenuated Japanese encephalitis vaccine at the same time point in large scale population of Chinese children (8 months old), within 56-day-post-immunized.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing EV71 and two measles attenuated live vaccine, EV71 and attenuated Japanese encephalitis vaccine and two measles attenuated live vaccine in people with Hand, Foot and Mouth Disease (HFMD), run by Chinese Academy of Medical Sciences 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 6 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: status not confirmed, as of the sponsor's last update on 28 Sep 2017. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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

Are results available for this study?

Results are not available in the source record.

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?

Evaluate the seropositive rate of anti-EV71 antibodies in serum of children before first vaccination (time frame: at 0 day before finishing 1st doses immunization). The study lists 8 primary outcomes in all. 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 28 Sep 2017.
