Study of Investigational Pneumococcal Vaccine in Healthy Adults, Toddlers and Infants

Safety and Immunogenicity of Pneumococcal Protein Vaccine (PPrV) in Healthy Adults, Toddlers and Infants in Bangladesh

This study is designed to explore the safety and tolerability of an investigational pneumococcal vaccine through a step-down enrollment.

Primary Objective:

• To evaluate the safety and tolerability of an investigational pneumococcal vaccine.

Secondary Objective:

• To evaluate the immunogenicity of an investigational pneumococcal vaccine.

Study Overview

• Status: Completed
• Conditions: Pneumonia; Pneumococcal Infections; Streptococcus Pneumoniae Infections
• Intervention / Treatment: Biological: Pneumococcal Vaccine High Dose (Formulation 1); Biological: Tris buffered saline (Placebo); Biological: Pneumococcal Vaccine Low Dose (Formulation 2); Biological: Pneumococcal Vaccine Middle Dose (Formulation 3); Biological: Pneumococcal Vaccine Middle Dose (Formulation 4)

Detailed Description

All adult participants will receive a single injection of study vaccine or placebo. After satisfactory safety evaluation, toddler participants will receive a single injection of study vaccine or placebo. After satisfactory safety evaluation, infant participants will receive 3 injections of study vaccine or placebo in dose-ascending order (low, medium, and high dose), with a safety evaluation after each dose level before the study proceeds to the next higher dose. All participants will undergo immunogenicity testing and monitoring for safety.

• Accepts Healthy Volunteers: No
• Genders Eligible for Study: All

Description

Inclusion Criteria:

Adults:

• Aged 18 to 50 years on the day of inclusion.
• Informed consent form has been signed and dated. If the subject is unable to read the informed consent form, a site-defined standard procedure will be followed to ensure subject understanding of the process and will be marked by the subject and signed by a witness.
• Able to attend all scheduled visits and to comply with all trial procedures.

Infants and Toddlers:

• Aged 6 to 7 weeks (42 to 49 days) for infants and 12 to 13 months for toddlers on the day of inclusion
• Born at full term of pregnancy (≥37 weeks) and having a weight ≥ 60% of the median weight for Bangladesh as measured by the "weight-to-length" index.
• Informed consent form has been signed and dated by the parent(s) or other legally acceptable representative (and by an independent witness if required by local regulations). If the subject's parent(s) or other legally acceptable representative is unable to read the informed consent form, a procedure will be followed to ensure his/her understanding of the process and will be marked by the subject's parent(s) or other legally acceptable representative and signed by a witness.
• Subject and parent/guardian are able to attend all scheduled visits and to comply with all trial procedures.

Exclusion Criteria:

• (Adults only): Subject is pregnant, or lactating, or of childbearing potential (to be considered of non-childbearing potential, a female must be pre-menarche or post-menopausal for at least 1 year, surgically sterile, or using an effective method of contraception or abstinence from at least 4 weeks prior to vaccination and until at least 4 weeks after vaccination).
• Participation or planned participation in another clinical trial investigating a vaccine, drug, medical device, or medical procedure in the 4 weeks preceding the first trial vaccination except if non-interventional follow-up for an earlier study (e.g., long-term surveillance).
• Receipt of any vaccine in the 4 weeks preceding the first trial vaccination, or planned receipt of any vaccine in the 4 weeks following the trial vaccination.
• Previous vaccination against S. pneumoniae (in the previous 5 years).
• History of pneumococcal infection (confirmed microbiologically) within 5 years.
• Receipt of blood or blood-derived products in the past 3 months, which might interfere with assessment of the immune response.
• Known or suspected congenital or acquired immunodeficiency; or receipt of immunosuppressive therapy such as anti-cancer chemotherapy or radiation therapy within the preceding 6 months; or long-term systemic corticosteroid therapy (prednisone or equivalent for more than 2 consecutive weeks within the past 3 months).
• Known systemic hypersensitivity to any of the vaccine components, or history of a life-threatening reaction to the vaccine used in the trial or to a vaccine containing any of the same substances.
• Bleeding disorder, including thrombocytopenia contraindicating intramuscular (IM) vaccination, or receipt of anticoagulants in the 3 weeks preceding inclusion.
• Deprived of freedom by an administrative or court order, or in an emergency setting, or hospitalized involuntarily.
• Current alcohol abuse or drug addiction.
• Chronic illness that, in the opinion of the Investigator, is at a stage where it might interfere with trial conduct or completion.
• (Adults only): Identified as employees of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, as well as family members (i.e., immediate, husband, wife and their children, adopted or natural) of the employees or the Investigator.
• (Infants and Toddlers only): Parents or guardians identified as employees of the Investigator or study center, with direct involvement in the proposed study or other studies under the direction of that Investigator or study center, as well as family members (i.e., immediate, husband, wife and their children, adopted or natural) of the employees or the Investigator.
• Febrile illness (temperature ≥38.0°C) or moderate or severe acute illness/infection (according to Investigator judgment) on the day of vaccination.
• Receipt of oral or injected antibiotic therapy within 72 hours prior to any blood draw (for immunogenicity assessment).
