Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 1 year to 5 years
  • All sexes
  • Healthy volunteers accepted
  • Child

Who may be able to join

  • 1 to 5 years of age, previously vaccinated with three or four doses of IPV.
  • Healthy without obvious medical conditions that preclude entry of the subject into the study as established by the medical history and physical examination.
  • Written informed consent obtained from 1 or 2 parent(s) or legal guardian(s) as per country regulations.

Who cannot join

  • Previous vaccination against poliovirus outside the national immunization schedule.
  • Any confirmed or suspected immunosuppressive or known immunodeficient condition including human immunodeficiency virus (HIV) infection.
  • Family history of congenital or hereditary immunodeficiency.
  • Major congenital defects or serious uncontrolled chronic illness (neurologic, pulmonary, gastrointestinal, hepatic, renal, or endocrine).
  • Known allergy to any component of the study vaccines or to any antibiotics.

Show all 9Show fewer
  • Acute severe febrile illness at day of vaccination deemed by the Investigator to be a contraindication for vaccination (the child can be included at a later time if within age window and all in/exclusion criteria are met.).
  • Member of the subject's household (living in the same house or apartment unit) has received OPV in the last 3 months.

About this study

Official title: A Phase 4 Study to Evaluate the Safety and Immunogenicity of Monovalent Oral Polio Vaccine Type 2 in Healthy IPV-vaccinated Children Aged 1 to 5 Years in Lithuania

A Phase 4 study to evaluate the safety and immunogenicity of monovalent oral polio vaccine type 2 in healthy IPV-vaccinated children aged 1 to 5 years in Lithuania.

Read the detailed description

Sabin 2 will be withdrawn from routine use globally from April 2016 as per the SAGE recommendations at the time of writing this protocol. After this cessation of OPV2, stockpiles of mOPV2 will be maintained for potential use if necessary in response to a future outbreak. However, there is a risk of cVDPV2 from Sabin 2 in settings of low population immunity. Research is ongoing to develop vaccines that are genetically more stable than the currently available Sabin 2-containing OPVs. To generate data on immunogenicity, safety, and genetic stability on the Sabin 2 vaccine (mOPV2) and as a future comparator for new polio vaccine research after the global switch from tOPV to bOPV, this study with mOPV2 is performed to evaluate safety, immunogenicity (humoral and intestinal) and genetic stability endpoints of mOPV2 in children aged 1 to 5 years for better understanding of the stockpile use of this vaccine, and any potential new polio vaccine with a type 2 component in the future.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Sabin mOPV2Biological

    Also called mOPV2

    Polio Sabin™ Mono Two (oral) is a licensed, monovalent, live attenuated poliomyelitis virus vaccine of the Sabin strain Type 2 (P 712, Ch, 2ab), propagated in MRC5 human diploid cells. Each two-drop dose (0.1 mL) contains not less than 105.0 CCID50 of Type 2. Magnesium chloride is used as a stabilizer. Polio Sabin™ Mono Two (Oral) contains trace amounts of neomycin sulphate and polymyxin B sulphate.

    One dose of vaccine (0.1 mL) is contained in two drops which are delivered from the polyethylene dropper supplied with vaccine.

What is being measured

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

  1. SAEs and Severe AEs

    Incidence of SAEs and severe AEs grade 3 considered consistent with a causal association to study vaccine throughout the study period in children 1 to 5 years.

    Measured: 3 months

  2. Seroprotection Rate of Type 2 Polio Neutralizing Antibodies.

    Seroprotection rate at type 2 polio neutralizing antibodies measured at D28 after the first dose of mOPV2.

    Measured: 1 month

Secondary outcomes (2)
  1. Seroprotection Rate for Type 2 Polio Neutralizing Antibodies.

    Seroprotection rate for type 2 polio neutralizing antibodies measured at D 28 after the secon dose of mOPV2.

    Measured: 3 months

  2. Incidence of Any Serious Adverse Events (SAEs), Any Solicited AEs, Any Unsolicited AEs, and Any Important Medical Events (IMEs).

    Incidence, severity and relationship) of any serious adverse events (SAEs), any solicited AEs, any unsolicited AEs, and any Important Medical Events (IMEs) with the exception of severe related AEs. (primary objective), as well as any laboratory deviations of one or two doses of SABIN mOPV2 in healthy IPV-vaccinated children aged 1 to 5 years.

    Measured: 3 months

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Sabin mOPV2 in people with Poliomyelitis, run by Fidec Corporation.

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 9 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 14 Jan 2020. Status can change between updates, so confirm with the study contact before making plans.

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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 16 Dec 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?

SAEs and Severe AEs (time frame: 3 months). 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?

On the ClinicalTrials.gov record for NCT02582255, 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 14 Jan 2020.
