About this study

Official title: Evaluation of the Safety and Preliminary Immunogenicity of Inactivated Rotavirus Vaccine (Vero Cell) in Healthy Population: a Randomized, Double-blind, Placebo Parallel-controlled Phase I Clinical Trial

This study is a randomized, double-blinded, placebo-controlled, Phase 1, dose-escalation study to evaluate the safety, reactogenicity and immunogenicity of Inactivated Rotavirus Vaccine (IRV) performed in healthy adult (aged 18-49 years), adolescent (aged 6-17 years) and infant subjects (aged 2-71 months). Primary objectives of the clinical trial include assessing the safety and tolerability of IRV given at two and three dose levels and comparing the safety and tolerability of IRV after each vaccination, between dosage groups, and by pre-vaccination rotavirus immune status. Secondary objective of the clinical trial is immunogenicity evaluation after each vaccination, between dosage groups, and by pre-vaccination rotavirus immune status.

Read the detailed description

This clinical trial aimed to evaluate safety and immunogenicity effect of IRV(Vero cell)in Chinese healthy adults, adolescents and infants. The subjects were divided into 5 groups. Two dose and three dose levels will be evaluated. Adult (aged 18-49 years), adolescents (aged 6-17 years), infant subjects (aged 7-71 months) and infant subjects (aged 2-6 months) will receive intramuscular (IM) injection on Days 0 and 28. Infant subjects (aged 2-6 months) subjects will receive intramuscular (IM) injection on Days 0 , 28 and 56. Three dose subgroups (low dose, medium dose and high dose were included in each age group. To maintain blindness in the trial, subjects were randomized in a 3:1 ratio to receive different dosages of the vaccine group or placebo group. In the analysis, the placebo subjects of the same age group were combined to ensure that the analysis ratio of the experimental vaccine group to the placebo group is 1:1. Therefore, 24 subjects in the experimental vaccine group and 8 subjects in the placebo group were chose in each dose group. Subjects were randomized to receive different dosages of the vaccine or placebo. Vaccination was performed in the adult group first, then on the adolescents, and on the infants last. Within each age group, dose-escalation with the principle from low to high dosage.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Low dosage IRV on a 0- and 28-day schedule, Medium dosage IRV on a 0- and 28-day schedule and High dosage IRV on a 0- and 28-day schedule in people with Rotavirus Infection, 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 21 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 10 Dec 2020. 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?

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?

Safety index-incidence of adverse reactions/events (time frame: 0-30 minutes after the first dose vaccination). The study lists 19 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 NCT04626856, 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 10 Dec 2020.
