05/24/2021 - 06:45 AM
Pfizer Inc. (NYSE: PFE) today announced that the first enrolled subjects have received their immunizations as part of a new study in adults ages 65 or older exploring the coadministration of the company’s 20-valent pneumococcal conjugate vaccine (20vPnC) candidate following a booster dose of the Pfizer-BioNTech COVID-19 Vaccine, currently authorized by the Food and Drug Administration (FDA) under an Emergency Use Authorization (EUA). The primary objective in the trial is to describe safety when both vaccines are co-administered, with follow up six months after vaccination. Secondary objectives are to describe immune responses produced by each of the vaccines.
The trial will include 600 adults who will be recruited from the pivotal Phase 3 Pfizer-BioNTech COVID-19 Vaccine trial and will have received their second dose of the vaccine at least six months prior to entering the coadministration study. The participants are being randomized to one of three groups:
20vPnC plus Pfizer-BioNTech COVID-19 Vaccine booster, which is a third dose of the Pfizer-BioNTech COVID-19 Vaccine
20vPnC plus placebo
Pfizer-BioNTech COVID-19 Vaccine booster plus placebo
