• PENBRAYA™ provides the broadest serogroup coverage (meningococcal groups A, B, C, W and Y) of any meningococcal vaccine available in the U.S. and has the potential to help simplify complex vaccination schedule in the U.S.
• The FDA’s decision is based on data from Phase 2 and Phase 3 trials, which demonstrated that PENBRAYA has robust immunogenicity non-inferior to Trumenba^® + Menveo^® for all serogroups and was well-tolerated with a favorable safety profile
• The vaccine further advances Pfizer’s vaccine portfolio and builds on more than 20 years of expertise and knowledge in the prevention of meningococcal disease

Pfizer Inc. (NYSE: PFE) announced today that the U.S. Food and Drug Administration (FDA) has approved PENBRAYA™ (meningococcal groups A, B, C, W and Y vaccine), the first and only pentavalent vaccine that provides coverage against the most common serogroups causing meningococcal disease in adolescents and young adults 10 through 25 years of age. PENBRAYA combines the components from two meningococcal vaccines, Trumenba^® (meningococcal group B vaccine) and Nimenrix^® (meningococcal groups A, C, W-135, and Y conjugate vaccine) to help protect against the five most common meningococcal serogroups that cause the majority of invasive meningococcal disease (IMD) globally.¹

“As a pioneer in vaccines, one of our goals is to deliver vaccines that evolve the paradigm and help simplify the standard of care in the U.S.,” said Annaliesa Anderson, Ph.D., Senior Vice President and Head, Vaccine Research and Development, Pfizer. “Today marks an important step forward in the prevention of meningococcal disease in the U.S. In a single vaccine, PENBRAYA has the potential to protect more adolescents and young adults from this severe and unpredictable disease by providing the broadest meningococcal coverage in the fewest shots.”

Meningococcal disease is an uncommon but serious illness that can lead to death within 24 hours and, for survivors, can result in life-altering, significant long-term disabilities.² PENBRAYA reduces the total number of doses needed for individuals to be fully vaccinated against the five most common serogroups, thereby streamlining the standard of care and potentially increasing the number of adolescents and young adults vaccinated.³ According to the U.S. Centers for Disease Control and Prevention (CDC), combining vaccines into fewer shots may mean that more adolescents and young adults get their recommended vaccines on time, resulting in fewer delays in protection against serious diseases.⁴ Routine use of PENBRAYA could also reduce IMD cases and associated mortality, the rate of long-term consequences of infection (sequelae) in survivors and costs associated with controlling outbreaks.⁵

“Nearly 9 out of 10 adolescents have incomplete protection against invasive meningococcal disease caused by the leading serogroups⁶,” said Jana Shaw, MD, Pediatrics Infectious Disease Specialist, Upstate Golisano Children's Hospital in Syracuse, NY. “For the first time, we have a single vaccine that helps protect against the five most common serogroups and has the potential to improve coverage and increase protection among adolescents and young adults.”

The FDA’s decision is based on the positive results from the Phase 2 and Phase 3 trials, including a randomized, active-controlled and observer-blinded Phase 3 trial assessing the safety, tolerability, and immunogenicity of the pentavalent vaccine candidate compared to currently U.S. licensed meningococcal vaccines, with the goal of determining immunologic noninferiority. The Phase 3 trial (NCT04440163) evaluated more than 2,400 patients from the U.S. and Europe.

The CDC Advisory Committee on Immunization Practices (ACIP) will meet on October 25, 2023, to discuss recommendations for the appropriate use of PENBRAYA in adolescents and young adults.

About PENBRAYA Regulatory Review

In September 2022, Pfizer announced positive results from a randomized, active-controlled and observer-blinded Phase 3 trial assessing the safety, tolerability, and immunogenicity of the PENBRAYA compared to currently licensed meningococcal vaccines, with the goal of determining immunologic noninferiority. The Phase 3 trial (NCT04440163) evaluated more than 2,400 patients from the U.S. and Europe. This trial was followed by the FDA’s acceptance of PENBRAYA’s Biologics License Application (BLA) in December 2022.

Indication for PENBRAYA

PENBRAYA is indicated for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroups A, B, C, W, and Y. PENBRAYA is approved for use in individuals 10 through 25 years of age.

PENBRAYA is administered as a two-dose series given six months apart.

Important Safety Information for PENBRAYA

• Fainting may happen after getting injectable vaccines, including PENBRAYA. Precautions should be taken to avoid falling and injury due to fainting
• Some individuals with weakened immune system may have reduced immune responses to PENBRAYA
• Individuals with certain complement deficiencies and individuals receiving treatment that inhibits terminal complement activation are at increased risk for invasive disease caused by N. meningitidis groups A, B, C, W, and Y, even if they develop antibodies following vaccination with PENBRAYA
• Vaccination with PENBRAYA may not protect all who receive the vaccine against N. meningitidis group A, B, C, W, and Y infections
• Vaccination with PENBRAYA does not substitute for vaccination with a tetanus toxoid–containing vaccine to prevent tetanus
• Guillain-Barré syndrome (GBS) has been reported following administration of other meningococcal vaccines. Ask your healthcare provider about the risks and benefits of PENBRAYA if you have a history of GBS
• The most common adverse reactions were pain at the injection site, fatigue, headache, injection site redness, muscle pain, injection site swelling, joint pain, and chills.
• Tell your healthcare provider if you are pregnant or plan to become pregnant

U.S. Indication for TRUMENBA^® (meningococcal group B vaccine)

TRUMENBA^® (meningococcal group B vaccine) is indicated for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroup B in individuals aged 10 through 25 years of age. Approval of TRUMENBA^® is based on the demonstration of immune response, as measured by serum bactericidal activity against four serogroup B strains representative of prevalent strains in the United States. The effectiveness of TRUMENBA^® against diverse serogroup B strains has not been confirmed.
