Official Title
A Phase 3, Randomized, Observer-Blinded, Placebo-Controlled Study to Evaluate the Efficacy, Safety, and Immunogenicity of a SARS-CoV-2 Recombinant Spike Protein Nanoparticle Vaccine (SARS-CoV-2 rS) With Matrix-M1™ Adjuvant in Adult Participants ≥ 18 Years With a Pediatric Expansion in Adolescents (12 to < 18 Years)
Brief Summary

This is a phase 3, randomized, observer-blinded, placebo-controlled study to evaluate the efficacy, safety, and immunogenicity of SARS-CoV-2 rS with Matrix-M1 adjuvant in adult participants and adolescent participants. Additionally providing a Booster Dose to fully vaccinated participants. A substudy is to be conducted at selected sites to evaluate the safety and immunogenicity of a fourth dose (second booster) of NVX-CoV2373 in adults and adolescents, previously fully vaccinated and subsequently boosted with a third dose (first booster)

Detailed Description

This is a Phase 3, randomized, observer-blinded, placebo-controlled study to evaluate the
efficacy, safety, and immunogenicity of SARS-CoV-2 rS with Matrix-M1 adjuvant in adult
participants ≥ 18 years of age (Adult Main Study) and adolescent participants 12 to <18 years
(Pediatric Expansion). Additionally, a Booster Amendment will allow for the evaluation of a
booster dose of SARS-CoV-2 rS with Matrix-M1 adjuvant in participants who completed the
primary series of active vaccine in the Adult Main Study or Pediatric Expansion, as well as
in participants who previously completed the primary series of an authorized/approved
COVID-19 vaccine. Additionally, a sub-study conducted at specific sites will allow for the
evaluation of a second booster dose of SARS-CoV-2 rS with Matrix-M1 adjuvant in participants
who completed the primary series of active vaccine in the Adult Main Study and Pediatric
Expansion as well as a booster dose in the Booster Amendment of the study.
