Official title

A Phase 1, Observer-Blind, Randomized, Active Controlled Trial to Evaluate the Safety and Reactogenicity of an Investigational Pneumococcal Vaccine in Toddlers 12 To 15 Months of Age Receiving a Single Booster Dose

Overview

The main purpose of this study is to assess the safety and reactogenicity of a single dose of the new pneumococcal vaccine (called Pn-MAPS30plus) in toddlers who have previously completed a two-dose primary vaccination series with PCV used in local immunization program. PCV20 will be used as a comparator for this study.

Interventions

  • Biological Pn-MAPS30plus
    Pn-MAPS30plus vaccine will be administered intramuscularly.
  • Combination product PCV20
    PCV20 vaccine will be administered intramuscularly.

Primary outcome measures

  • Number of Participants with Solicited Administration site Adverse Events (AEs) [Time frame: Day 1 to Day 7]
  • Number of Participants with Solicited Systemic Adverse Events (AEs) [Time frame: Day 1 to Day 7]
  • Number of Participants with Unsolicited AEs [Time frame: Day 1 to Day 30]
  • Number of Participants with Serious AEs (SAEs), Adverse Events of Special Interest (AESIs) and AEs Leading to Withdrawal [Time frame: Day 1 up to trial end (Month 6)]
  • Number of Participants with Hematological and Biochemical Laboratory Abnormalities [Time frame: On Day 8 compared to Day 1 (pre-vaccination)]

Eligibility criteria

Inclusion criteria

  • Participants' parent(s)/Legally acceptable representative \[LAR(s)\] who, in the opinion of the investigator, can and will comply with all protocol requirements.
  • Written or witnessed/thumb printed informed consent obtained from the participants' parent(s)/LAR(s) prior any study-specific procedure is performed.
  • A male or female between, and including, 12 to15 Months of age at the time of the study intervention administration.
  • Healthy participants or medically stable patients as established by medical history and clinical examination before entering the study.
  • To the best knowledge of the participant's parent(s)/LAR(s), the child has been eligible for pneumococcal vaccination and has completed a 2-dose primary series with PCV10.

Exclusion criteria

  • History of any reaction or hypersensitivity likely to be exacerbated by any component of the study intervention(s).
  • Hypersensitivity to latex.
  • History of microbiologically proven Invasive pneumococcal Disease (IPD).
  • Any confirmed or suspected immunosuppressive or immunodeficient condition, based on medical history and physical examination.
  • Major congenital defects, as assessed by the investigator.
  • Recurrent history or uncontrolled neurological disorders or any neuroinflammatory condition, congenital neurological conditions, encephalopathies, or seizures.
  • Condition that in the judgment of the investigator would make intramuscular injection unsafe.
  • Any other clinical condition that, in the opinion of the investigator, might pose additional risk to the participant due to participation in the study.
  • Use of any investigational or non-registered product (drug, vaccine, or invasive medical device) during the period beginning 30 days before the dose of study intervention(s), or their planned use during the trial period.
  • Previous vaccination with any pneumococcal vaccine other than PCV10.
  • Previous receipt of more than 2 pneumococcal vaccine doses (primary series or booster).
  • Planned administration/administration of any inactivated or otherwise non-live vaccine in the period starting 14 days before and ending 14 days after the dose of study intervention administration or planned administration/administration of any live vaccine in the period starting 28 days before and ending 28 days after the dose of study intervention administration, with the exception of inactivated influenza vaccine which may be administered but must be given at least 7 days before or 15 days after receipt of any study intervention.
  • Receipt of blood or plasma products or immunoglobulins, from 90 days before study intervention administration, or planned receipt up to 30 days of study intervention administration.
  • Chronic administration of immune-modifying drugs and/or planned use of long-acting immune-modifying treatments at any time up to the end of the study.
  • For corticosteroids: prednisone equivalent ≥0.5 mg/kg/day (maximum 20 mg/day) within 90 days prior for pediatric participants.
  • Inhaled and topical steroids are allowed.
  • Concurrent participation in another clinical study in which the participant has been or will be exposed to an investigational or non-investigational intervention.
  • Any child of trial personnel or their immediate dependents, family, or household members.
  • Child in care.
