About this study

Mumps is an acute infectious respiratory disease caused by the mumps virus (MuV), which occurs mainly in children and adolescents. Its main clinical symptoms were parotid gland suppurative swelling and pain with fever. The pathological changes and harm caused by mumps was not only confined to the parotid gland, on the contrary, the social harm caused by serious complications cannot be ignored. As mumps is a vaccine-preventable infectious disease, vaccination is a fundamental strategy for controlling mumps. So far, there are 13 genotypes of MuV. Based on the analysis of molecular epidemiology, the main epidemic strain of MuV in China was the F genotype. The commonly used vaccine strains represented only a small number of known genotypes, e.g. Jeryl-Lynn (JL) and Rubini strains, which belong to type A, Urabe strain belongs to type B, and L-Zagreb strains belongs to type D. Virus seed of Live Attenuated Mumps Vaccine (Human diploid cell) developed by the institute was SP-A strain, which was the first separation and preparation of the attenuated mumps viruses in China. SP-A belongs to F genotype, which was the domestic epidemic genotype. In addition, the cell substrate prepared for vaccine was human diploid cell (KMB-17 strain), which is much safer to use. The results of phase I and II clinical trials showed that the vaccine possessed good immunogenicity and good antigenic cross-reactivity in infants (8-24 months old).

Read the detailed description

This study will recruit 12,000 subjects and be divided into two stages. The first stage will evaluate the immunogenicity and safety of F-genotype mumps live attenuated vaccine (human diploid cells) after vaccination in 720 healthy children aged 5-11 years, and explore the detoxification in 144 subjects, who randomly selected from these 720 subjects. The second stage will evaluate the clinical protective efficacy, immunogenicity and safety of F-genotype mumps live attenuated vaccine (human diploid cells) after vaccination in 11280 healthy children aged 5-11 years.

Questions about this trial

What is this clinical trial studying?

A Phase 2/3 study testing Attenuated Mumps vaccine (KMB-17) in phase II and III and Attenuated Mumps vaccine (KMB-17) in phase III in people with Epidemic Parotitis, Mumps, run by Institute of Medical Biology, 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 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: status not confirmed, as of the sponsor's last update on 11 Oct 2023. 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 combined phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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?

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?

Phase II: Positive conversion rate of MuV hemagglutination inhibition antibody of Muv Vaccine (time frame: 28 day after the 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?
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 11 Oct 2023.
