A Study to Evaluate Safety and Immunogenicity of tOPV in 1 to 5 Years and at 6 Weeks of Age (T2-ABMG)

March 23, 2023 updated by: Fidec Corporation

A Phase 4 Study to Evaluate the Safety and Immunogenicity of Trivalent Oral Polio Vaccine in Healthy Polio Vaccinated Children 1 to 5 Years of Age and in Healthy Unvaccinated Infants at 6 Weeks of Age in the Dominican Republic

The purpose of this study is to assess the safety (serious adverse events [SAEs]), and severe adverse events [AEs] (grade 3 according to CTCAE 4.03) after one dose of SABIN tOPV in 1-5 year-old children and three doses of SABIN tOPV in 6 week-old infants, and immunogenicity (seroprotection rates for all 3 serotypes) 28 days after three doses of SABIN tOPV in vaccine-naïve infants.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This will be a single center, open study in children (aged 1 to 5 years) and vaccine-naïve infants, as follows: 50 OPV-vaccinated children aged 1 to 5 years to receive 1 dose of tOPV (Group 1); 104 vaccine-naïve infants to receive 3 doses of tOPV administered 28 days apart (Group 2)

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

1 month to 5 years (Child)

Accepts Healthy Volunteers

Yes

Description

Inclusion Criteria:

  1. Age:

    Group 1- Children aged 1-5 years, previously vaccinated with ≥ 3 doses of OPV. Group 2- Infants aged 6 weeks (-7 to +14 days) with no previous polio vaccinations.

  2. Healthy without obvious medical conditions that preclude the subject to be in the study as established by the medical history and physical examination.
  3. Written informed consent obtained from 1 or 2 parents or legal guardians as per Dominican Republic regulations.

Exclusion Criteria:

  1. Previous Vaccinations:

    Group 1: Previous vaccination against poliovirus outside of the national immunization schedule and any vaccine in the previous 4 weeks.

    Group 2: Any vaccination against poliovirus

  2. Group 2: Infants with birth weight (BW) < 2,500 gm.
  3. Any confirmed or suspected immunosuppressive or known immunodeficient condition including human immunodeficiency virus (HIV) infection.
  4. Family history of congenital or hereditary immunodeficiency.
  5. Major congenital defects or serious uncontrolled chronic illness (neurologic, pulmonary, gastrointestinal, hepatic, renal, or endocrine).
  6. Known allergy to any component of the study vaccines or to any antibiotics.
  7. Uncontrolled coagulopathy or blood disorder contraindicating intramuscular injections.
  8. Administration of immunoglobulins and/or any blood products since birth or planned administration during the study period.
  9. 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).
  10. Member of the subject's household (living in the same house or apartment unit) has received OPV in the last 3 months, or is scheduled to receive OPV during the study period.
  11. Subject who, in the opinion of the Investigator, is unlikely to comply with the protocol or is inappropriate to be included in the study for the safety or the benefit-risk ratio of the subject.

Experimental: Oral Polio Vaccine

Opvero™ (oral) is a trivalent, live attenuated poliomyelitis virus vaccine containing at least 6.0 log 50% cell culture infective dose (CCID50) of LS c2ab strain of live attenuated polio virus type 1, 5.0 log CCID50 of P712, Ch, 2ab strain of live attenuated polio virus type 2, 5.8 log CCID50 Leon I2aIb strain of polio virus type 3. Excipients: human albumin, HEPES buffer solution, magnesium chloride solution (containing polysorbate 80 and phenol red), hydrochloric acid or sodium hydroxide for pH adjustment.

The vaccine is presented as a suspension for oral administration. One dose of vaccine (0.1 ml) is contained in two drops which are delivered from the dropper supplied with the multidose container.
