If approved, the vaccine would provide the broadest serotype coverage of any pneumococcal conjugate vaccine in infants and children, and have the potential to help protect against more of the clinically significant remaining burden of disease
NEW YORK, NY, USA I January 06, 2023 I Pfizer Inc. (NYSE:PFE) today announced that the U.S. Food and Drug Administration (FDA) accepted for priority review a supplemental Biologics License Application (sBLA) for its 20-valent pneumococcal conjugate vaccine candidate (20vPnC) for the prevention of invasive pneumococcal disease (IPD) caused by the 20 Streptococcus pneumoniae (pneumococcus) serotypes contained in the vaccine in infants and children 6 weeks through 17 years of age, and for the prevention of otitis media caused by seven of the 20 Streptococcus pneumoniae serotypes contained in the vaccine.
Priority Review designation by the FDA reduces the standard sBLA review period by four months. The Prescription Drug User Fee Act (PDUFA) goal date for a decision by the FDA on the 20vPnC vaccine application is anticipated in April 2023. The FDA previously granted Pfizer’s 20vPnC Fast Track Designation in May 2017 and Breakthrough Therapy Designation in August 2020 for the pediatric indication for IPD.
“Today’s regulatory milestone further advances Pfizer’s commitment to the more than 20-year legacy of helping protect infants and children from invasive pneumococcal disease through conjugate vaccination,” said Annaliesa Anderson, Ph.D., Senior Vice President and Chief Scientific Officer, Vaccine Research and Development, Pfizer. “By offering the broadest serotype coverage by a pneumococcal conjugate vaccine against important serotypes causing pneumococcal disease in U.S. infants and children, 20vPnc, if approved, can help expand the protection for this vulnerable pediatric population.”
The regulatory submission is supported by results from the Phase 3 and Phase 2 clinical trial programs for the pediatric indication for 20vPnC. Three core Phase 3 pediatric studies contributed to data on the safety, tolerability, and immunogenicity of 20vPnC, including previously announced positive, top-line results of the pivotal U.S. Phase 3 study (NCT04382326). These studies collectively enrolled approximately 3,500 infants and 800 children of all ages. Further data from a Proof-of-Concept Phase 2 study (NCT03512288) in 460 U.S. infants that assessed the safety and immunogenicity of 20vPnC, with previously announced positive results, also supported the regulatory submission.
About 20vPnC
Pfizer’s 20vPnC pediatric vaccine candidate includes the 13 serotypes already included in Prevnar 13® – 1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F, and 23F. The seven new serotypes included in 20vPnC are global causes of IPD.1,2,3,4,5 and are associated with high case-fatality rates6,7,8,9 antibiotic resistance10,11 and or meningitis.12,13 Together, the 20 serotypes included in 20vPnC are responsible for the majority of currently circulating pneumococcal disease in the U.S. and globally.14,15,16,17,18,19,20
The supplemental Biologics License Application (sBLA) for 20vPnC includes for review indications in the following pediatric populations:
In September 2022, Pfizer announced positive top-line results from its pivotal Phase 3 study (NCT04546425) in infants in the European Union, and in November 2022, submitted the 20vPnC pediatric indication to the European Medicines Agency (EMA).
The FDA previously approved PREVNAR 20® (Pneumococcal 20-valent Conjugate Vaccine) on June 8, 2021, for the prevention of invasive disease and pneumonia caused by the 20 pneumococcus serotypes in the vaccine in adults ages 18 years and older.
