About this study
Official title: A Phase Ib Study to Evaluate the Safety and Immunogenicity of a Sabin Inactivated Poliovirus Vaccine (Vero Cell)
The purpose of this phase Ib study is to evaluate the safety of a Sabin Inactivated Poliovirus Vaccine (sIPV) in adults and children, and the safety and immunogenicity of it in infants. 20 adults aged 18~45 years and 20 children aged 4 years were only administered one dose of sIPV with high D antigen content. 20 infants aged 2 months (60~90 days) were administered three doses of sIPV with high D antigen content, on the month 0, 1, 2 schedule. Serum samples were collected before the 1st dose and 30 days after the 3rd dose vaccination to assess the immunogenicity in infants. Adverse events occurring within 30 days after each dose were collected to assess the safety.

The investigational High dosage Sabin IPV was all developed by Minhai Biotech Co., LTD. The antigen contents of type I, type II and type III polioviruses in the high dosage Sabin IPV were 22 DU, 65 DU and 65 DU. The vaccine was in liquid form, 0.5 ml per dose.
| Study group | Role | What they receive |
|---|---|---|
| Experimental Adult Group - High dosage | Experimental | One intramuscular injection of the investigational vaccine (0.5 ml); Intervention: one-dose regimen of high dosage investigational sIPV Intervention: Biological: one-dose regimen of high dosage investigational sIPV Receives: Biological: sIPV |

What is being measured
The primary outcome is the main question the study is designed to answer.
The seroconversion rates (SCRs) of each group 30 days after three-dose regimen
Subjects whose pre-immune antibody level < 1:8 and post-immune antibody level ≥ 1:8, or those whose pre-immune antibody level ≥ 1:8 and the increase of post-immune antibody level ≥ 4 folds are considered seroconverted.
Measured: 28~42 days
The geometric mean titer (GMT) of each group 30 days after three-dose regimen
GMT of each group 28~42 days after three-dose regimen
Measured: 28~42 days
The geometric mean fold increase (GMI) of each group 30 days after three-dose regimen
The GMI is the increase of post-immune GMT from pre-immune GMT
Measured: 28~42 days
Secondary outcomes (2)
The incidences of adverse reactions of each group occurred within 30 days after each injection
The number of participants who had adverse reactions divided by the number of all participants
Measured: 30 days
The incidences of adverse events (AEs) of each group occurred within 30 days after each injection
The number of participants who had adverse events (AEs) divided by the number of all participants
Measured: 30 days

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing sIPV in people with Polio, run by Jiangsu Province Centers for Disease Control and Prevention 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 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 11 Feb 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. 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 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.
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?
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?
The seroconversion rates (SCRs) of each group 30 days after three-dose regimen (time frame: 28~42 days). 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?
On the ClinicalTrials.gov record for NCT04264546, 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 11 Feb 2020.
