Positive Top-line Results of Pfizers Phase 3 Study of PREVNAR 20

Pfizer Inc today announced positive top-line results from a Phase 3 study (B7471004) evaluating the safety and immunogenicity of PREVNAR 20 (Pneumococcal 20-valent Conjugate Vaccine) in adults 65 years of age or older when administered at the same time as the seasonal influenza vaccine (SIIV, Fluad Quadrivalent [adjuvanted], 2020/2021 strains). Responses elicited by PREVNAR 20 for all 20 serotypes and by seasonal influenza vaccine when given together were noninferior (the study’s primary immunogenicity objectives) to those elicited by the vaccines when administered one month apart. The safety profile of PREVNAR 20 was similar when the vaccines were coadministered as compared to when each vaccine was administered separately, one month apart.

“We are encouraged by these results showing that these two vaccines can be administered at the same time without affecting the immune protection provided by either vaccine or changing the safety profile,” said Kathrin U. Jansen, Ph.D., Senior Vice President and Head of Vaccine Research & Development, Pfizer. “This study adds to the body of evidence further supporting that pneumococcal conjugate vaccines may be coadministered with influenza vaccines, this time studied with the adjuvanted influenza vaccine. We are committed to vaccine development to help address needs across many respiratory diseases.”

Across 66 investigator sites in the United States, a total of 1,796 participants were enrolled and randomized, with 1,727 of participants completing the study.

“Both PREVNAR 20 and the influenza vaccine are important for helping protect adults against pneumococcal pneumonia and the flu respectively; however, vaccination rates decline when someone needs to make multiple appointments to receive these vaccines,” said Luis Jodar, Ph.D., Senior Vice President and Chief Medical Officer, Pfizer Vaccines. “The results of this trial supports current CDC clinical guidance allowing coadministration during a single doctor or pharmacy appointment, so that more adults are able to help protect themselves against both of these respiratory diseases.”

Pfizer will seek to present and publish detailed outcomes from this clinical trial at a future date. Additionally, in May 2021, Pfizer announced the initiation of a Phase 3 clinical trial exploring coadministration of PREVNAR 20 and a booster dose of COMIRNATY (COVID-19 Vaccine, mRNA) in adults ages 65 or older.

About PREVNAR 20
PREVNAR 20 is Pfizer’s next-generation pneumococcal conjugate vaccine that includes capsular polysaccharide conjugates for the 13 serotypes (1, 3, 4, 5, 6A, 6B, 7F, 9V, 14, 18C, 19A, 19F and 23F) already included in Prevnar 13 (Pneumococcal 13-valent Conjugate Vaccine [Diphtheria CRM197 Protein]). The vaccine also contains capsular polysaccharide conjugates for seven additional serotypes (8, 10A, 11A, 12F, 15B, 22F and 33F) that cause invasive pneumococcal disease (IPD), and have been associated with high case-fatality rates, antibiotic resistance, and/or meningitis PREVNAR 20 contains the broadest serotype coverage and helps protect against more strains of the bacteria that cause pneumococcal pneumonia than any other conjugate vaccine available.

On June 8, 2021, Pfizer announced the U.S. Food and Drug Administration (FDA) approved, based on accelerated approval and priority review, PREVNAR 20 for the prevention of invasive disease and pneumonia in adults age 18 years or older. On February 26, 2021, the European Medicines Agency (EMA) accepted for review Pfizer’s Marketing Authorization Application (MAA) for the 20-valent pneumococcal conjugate vaccine candidate, as submitted for the prevention of invasive disease and pneumonia caused by S. pneumoniae serotypes in the vaccine in adults ages 18 years and older. The formal review process by the EMA’s Committee for Medicinal Products for Human Use (CHMP) currently is ongoing.

PREVNAR 20 U.S. Indications

  • PREVNAR 20 is a vaccine indicated for active immunization for the prevention of pneumonia and invasive disease caused by Streptococcus pneumoniae serotypes 1, 3, 4, 5, 6A, 6B, 7F, 8, 9V, 10A, 11A, 12F, 14, 15B, 18C, 19A, 19F, 22F, 23F, and 33F in adults 18 years of age and older
  • This indication for the prevention of pneumonia caused by S. pneumoniae serotypes 8, 10A, 11A, 12F, 15B, 22F, and 33F is approved under accelerated approval based on immune responses as measured by opsonophagocytic activity (OPA) assay. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.

IMPORTANT SAFETY INFORMATION

  • PREVNAR 20 should not be given to anyone with a history of severe allergic reaction to any component of PREVNAR 20 or any diphtheria toxoid–containing vaccine
  • Some adults with weakened immune systems may have a lower response to PREVNAR 20. Safety data are not available for these groups. Your healthcare provider can tell you if PREVNAR 20 is right for you
