About this study
Official title: A Randomized, Blind, Controlled Clinical Trial to Evaluate Safety and Immunogenicity of Live Attenuated Varicella Vaccine After a Two-dose Vaccination Course in Healthy Population Aged ≥13 Years Old
This a randomized, blind, controlled clinical trial of live attenuated varicella vaccines manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd .The purpose of this study is to evaluate the immunogenicity of a two doses vaccination of investigational vaccine with 0,28 day, 0,42 day and 0,56 day immunization schedule in population aged ≥13 years old.
Read the detailed description
This study is a randomized, blind, controlled phase # clinical trial in population aged ≥13 years old. The experimental vaccine will be manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd.A total of 2400 subjects aged 13 years and older will be enrolled with1200 subjects in 13 ~ 17 years old group and1200 subjects in 18 years and older group.960 subjects in each age group will be randomly divided into experimental group and control group according to 1:1 ratio,and subjects will receive two doses of vaccine with the immunization course of 0,28 days, 0,42 days or 0,56 days. An additional 240 subjects in each age group will be randomly divided into experimental group and control group according to 2:1 ratio to receive two doses of the experimental vaccine or placebo with the immunization course of 0, 70 days.In addition,400 subjects including 320 people of experimental group in different immunization course according to the difference of age and 80 people of placebo group according to the difference of age will be selected to collect blood about 3ml each time to evaluate immunity persistence of live attenuated varicella vaccines at 3 and 5 years after the whole immunization.

Questions about this trial
What is this clinical trial studying?
A Phase 3 study testing Live attenuated varicella vaccines manufactured by Sinovac (Dalian) Vaccine Technology Co., Ltd and Live attenuated varicella vaccines manufactured by Changchun BCHT Biotechnology Co.,Ltd in people with Varicella, run by Sinovac (Dalian) Vaccine Technology Co., Ltd. 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 3 inclusion and 18 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 8 Mar 2024. 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 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?
Seroconversion rate of the antibody (time frame: Day 28 after the whole schedule). The study lists 2 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 8 Mar 2024.
