Phase 2b Study of a Respiratory Syncytial Virus and Human Metapneumovirus (RSV+HMPV) Protein Vaccine Candidate in Adults 60 Years of Age and Older
A Phase 2b, Randomized, Placebo-controlled, Observer-blind Study in Adults 60 Years of Age and Older to Evaluate the Efficacy, Safety, and Immunogenicity of a Bivalent Protein Vaccine Candidate Against Respiratory Syncytial Virus (RSV) and Human Metapneumovirus (HMPV)
Study VCA25397 is a Phase 2b, observer-blind, randomized, placebo-controlled, parallel, case-driven proof of concept study that will enroll approximately 8000 adults aged 60 years and older to assess the clinical efficacy, safety, and immunogenicity of a single IM (intramuscular) injection of the bivalent RSV+HMPV protein vaccine candidate.
The study will include a Safety Lead-in Cohort that will be enrolled first and will comprise 200 participants aged 60 years and older randomized in a 1:1 ratio to receive either RSV+HMPV protein vaccine or placebo (100 participants per arm).
The enrollment of the Main Cohort will start after the completion of the ESDR (Early Safety Data Review), pending a positive outcome. For the Main Cohort, 7800 participants (3900 participants per arm) will be randomized in a 1:1 ratio to receive either RSV+HMPV protein vaccine or placebo.

説明
Inclusion Criteria:
- Aged 60 years or older on the day of inclusion
- Participants who, as determined by medical evaluation including medical history, physical examination, and clinical judgment of the Investigator are eligible for inclusion
Exclusion Criteria:
- Known/suspected immunodeficiency; immunosuppressive therapy/immunomodulators in past 6 months; long-term systemic corticosteroids (eg, prednisone for more than 2 weeks in past 3 months); history of immune-mediated neurological disease. Of note, persons living with stable HIV are not excluded
- Known systemic hypersensitivity to any of the study intervention components or history of a life-threatening reaction to the study interventions used in the study or to a product containing any of the same substances
- Chronic illness that, in the opinion of the investigator, is at a stage where it might interfere with study conduct or completion
- Previous history of Guillain-Barré Syndrome (GBS)
- Previous vaccination against RSV and/or HMPV (with a licensed or investigational vaccine either as a monovalent vaccine or any combination of the antigens) or previous receipt of RSV and/or HMPV monoclonal antibody
The above information is not intended to contain all considerations relevant to a participant's potential participation in a clinical trial.
