About this study

Official title: A Randomized, Blind, Placebo-controlled Phase I Clinical Trial to Evaluate the Safety and Immunogenicity of Recombinant Norovirus Bivalent (GI. 1 / GII. 4) Vaccine (Hansenulapolymorpha) in Healthy People Aged 6 Months to 59 Years

A total of 450 subjects were enrolled, divided into four age groups, including 18-59 years, 6-17 years, 3-5 years, and 6-35 months. There are three types of the test vaccine component in each age group. A total of 30 people in each dose group were vaccinated with the test vaccine or placebo 1 or placebo 2, respectively, in a ratio of 3: 1: 1.

The 18-59-year-old, 6-17-year-old, and 3-5-year-old age groups were vaccinated 2 times at a time interval of 28 days. The 6-35 month age group is divided into two groups, Group 1 is inoculated with 2 doses interval of 28 days each, and Group 2 is inoculated with 3 doses interval of 28 days.

Read the detailed description

From January to April 2020, this study was affected by the COVID-19 epidemic, which caused the two groups(6-17-year-old,3-5-year-old) of subjects to vaccinate beyond the window and deviate from the experimental plan. After communication between the researcher, the sponsor and the statistician, it was decided to restart the Phase I clinical trials of these two groups.

Being tested
Norovirus Bivalent (GI.1 / GII.4) Vaccine(low), Norovirus Bivalent (GI.1 / GII.4) Vaccine(middle), Norovirus Bivalent (GI.1 / GII.4) Vaccine(high), Normal saline, Aluminum adjuvant
Medical subject headings

What is being measured

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

  1. AE of local and systemic reactions within 30 minutes after each dose

    Measured: 30 minutes

  2. All active AEs within 0-7 days after each dose

    Active AE: Local and systemic adverse reactions occurring within 0-7 days after each dose of vaccination

    Measured: 7 days

  3. All non-active collection AEs within 0-28(30) days after each dose

    Adverse events other than active AE include solicitation adverse events reported in addition to the specified solicitation time window

    Measured: 28(30) days

  4. All SAEs within 6 months after the last dose is vaccinated

    Measured: 6 months

Secondary outcomes (4)
  1. Calculate geometric mean titer (GMT) of NoV GI.1 and GII.4 IgG antibodies

    Measured: 28 days after the full vaccination

  2. Calculate positive rate of NoV GI.1 and GII.4 IgG antibodies

    Measured: 28 days after the full vaccination

  3. Calculate NoV GI.1 and GII.4 HBGA-blocking antibody titers

    Measured: 28 days after the full vaccination

  4. Calculate NoV GI.1 and GII.4 HBGA-blocking antibody positive rates

    Measured: 28 days after the full vaccination

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Norovirus Bivalent (GI.1 / GII.4) Vaccine(low), Norovirus Bivalent (GI.1 / GII.4) Vaccine(middle) and Norovirus Bivalent (GI.1 / GII.4) Vaccine(high) in people with Norwalk Gastroenteritis and Norovirus Infections, run by National Vaccine and Serum Institute, China 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 4 inclusion and 16 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 22 Apr 2021. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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?

AE of local and systemic reactions within 30 minutes after each dose (time frame: 30 minutes). The study lists 4 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 22 Apr 2021.
