About this study

Official title: A Phase II, Randomized, Double-Blind, Dosage, Safety and Immunogenicity Trial of Intramuscular Norovirus GI.1/GII.4 Bivalent Virus-Like Particle Vaccine Combined With Aluminum Hydroxide Adjuvant in Children, Toddlers, and Infants

Read the detailed description

The vaccine being tested in this study is called norovirus GI.1/GII.4 bivalent virus-like particle (VLP) vaccine with aluminum hydroxide. The norovirus vaccine is being tested to assess different formulations of the vaccine that will then be further developed. This study will look at the number of antibodies to norovirus formed in children, toddlers and infants who are administered different formulations of the norovirus vaccine.

The study enrolled 840 patients. Participants will be randomly assigned (by chance) to one of ten treatment groups-which will remain undisclosed to the participant and study doctor during the study (unless there is an urgent medical need).

All participants in Cohort 1 will be vaccinated on Day 1 and Day 29 of the study, and all participants in Cohort 2 will be vaccinated on Day 1, Day 56, and Day 112. All treatment groups in Cohort 1 will receive either one dose of the norovirus vaccine, or two doses. One treatment group in Cohort 2 will receive 2 doses of the norovirus vaccine, and the other group will receive 3. In order to keep the treatment undisclosed to the participant and the doctor in Cohort 1, those randomized to the one-dose groups will receive the norovirus vaccine on Day 1, followed by a dose of placebo vaccine on Day 29. In order to keep the treatment arms undisclosed to the participant and the doctor in Cohort 2, those randomized to the two-dose groups will receive the norovirus vaccine on Day 1 and Day 56, followed by a dose of placebo vaccine on Day 112. Placebo vaccine is saline solution. Participants will be asked to record any symptoms that may be related to the vaccine or the injection site in a diary card for 7 days after each vaccination.

This multi-center trial will be conducted in Finland, Panama, and Colombia. The overall time to participate in this study is up to 210 days for participants in Cohort 1 and up to 293 Days for participants in Cohort 2. Participants in Cohort 1 will make 6 visits to the clinic, and participants in Cohort 2 will make 10 visits to the clinic.

Individual data sharing: Yes: Takeda makes patient-level, de-identified data sets and associated documents available after applicable marketing approvals and commercial availability have been received, an opportunity for the primary publication of the research has been allowed, and other criteria have been met as set forth in Takeda's Data Sharing Policy (see www.TakedaClinicalTrials.com/Approach for details). To obtain access, researchers must submit a legitimate academic research proposal for adjudication by an independent review panel, who will review the scientific merit of the research and the requestor's qualifications and conflict of interest that can result in potential bias. Once approved, qualified researchers who sign a data sharing agreement are provided access to these data in a secure research environment.

Individual participant dataSharing planned: Yes. Takeda makes patient-level, de-identified data sets and associated documents available after applicable marketing approvals and commercial availability have been received, an opportunity for the primary publication of the research has been allowed, and other criteria have been met as set forth in Takeda's Data Sharing Policy (see www.TakedaClinicalTrials.com/Approach for details). To obtain access, researchers must submit a legitimate academic research proposal for adjudication by an independent review panel, who will review the scientific merit of the research and the requestor's qualifications and conflict of interest that can result in potential bias. Once approved, qualified researchers who sign a data sharing agreement are provided access to these data in a secure research environment.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing GI.1/GII.4 (15/15), GI.1/GII.4 (15/50) and GI.1/GII.4 (50/50) in people with Norovirus, run by Takeda at 12 sites in 3 countries.

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 22 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 1 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 12 sites in Finland, Panama, Colombia. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 1 Apr 2019). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Percentage of Participants With a Seroresponse (Pan-Ig ELISA) in Cohort 1 (time frame: Day 57). The study lists 13 primary outcomes in all. 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 NCT02153112, which also lists 1 linked publication.

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 1 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
