“The approval of TRUMENBA reflects our dedication to advancing novel vaccines that can help protect adolescents and young adults, a population at an increased risk for meningococcal disease caused by MenB,” said Luis Jodar, Chief Medical and Scientific Affairs Officer, Medicines Development, Scientific and Clinical Affairs, Pfizer Vaccines. “Though uncommon, MenB disease is unpredictable, can progress rapidly and is associated with a significant risk of death and long-term disability, demonstrating the value of immunization as a preventive measure.”

Meningococcal Group B (MenB) is Responsible for 60 Percent of Meningococcal Disease Cases in Adolescents and Young Adults in Europe

Early symptoms can be misinterpreted as the flu, but meningococcal disease can lead to death within 24 hours.3 Despite antibiotic treatment, 10 to 15 percent of people with meningococcal disease will die.3 Of those adolescents who survive, three in five experience significant physical and mental disabilities.4 Adolescents remain a very important group for vaccination, as up to a quarter may be asymptomatic carriers of Neisseria meningitidis.5

“We are steadfast in our commitment to progress and shape the future of vaccines to help address serious health threats worldwide and make the greatest public impact,” said Susan Silbermann, President and General Manager, Pfizer Vaccines. “We are also focused on consistent, reliable supply for all the vaccines we manufacture, including a full 36-month shelf life with TRUMENBA. With the EC approval of TRUMENBA, Pfizer now has a comprehensive portfolio of vaccines to help prevent five of the most common disease-causing meningococcal serogroups in this region.”

Pfizer continues to invest significantly in manufacturing processes and facilities to ensure a sufficient supply of TRUMENBA in Europe, where the majority of meningococcal disease cases (60 percent) among adolescents and young adults are caused by serogroup B.1

The EC decision is based on results from a clinical development program in which more than 20,000 adolescents and adults were evaluated, approximately 15,000 of whom received TRUMENBA.6,7,8,9,10,11,12 The data demonstrate that TRUMENBA induces protective serum bactericidal antibody responses to diverse MenB test strains that are representative of disease causing strains, and the vaccine has an established safety profile.13 In clinical studies, the most common adverse reactions observed were injection site pain, redness and swelling at the vaccination site, headache, fatigue, chills, diarrhea, muscle pain, joint pain and nausea. The posology includes both two- and three-dose schedules, providing flexibility for healthcare professionals to administer the vaccine depending on individuals’ risk of exposure and susceptibility to MenB. The marketing authorization granted by the EC is valid in all European Union (EU) member states, plus Iceland, Liechtenstein and Norway. Additional marketing authorization application reviews for TRUMENBA are under way in other countries.

Pfizer’s Meningococcal Vaccines portfolio includes vaccines that help protect against five of the most common disease-causing serogroups — A, B, C, W, and Y (approvals varying by country) — which can threaten the health of people at various points in their lives.14 Since its first approval in the U.S. in 2014, TRUMENBA has been administered to an estimated 600,000 adolescents and young adults.15 The risk of contracting meningococcal disease varies year to year, by age group, and by the country one travels to or lives in.16

TRUMENBA® (Meningococcal Group B Vaccine) is a vaccine indicated for individuals 10 through 25 years of age for active immunization to prevent invasive disease caused by Neisseria meningitidis group B.

The effectiveness of the two-dose schedule of TRUMENBA against diverse Neisseria meningitidis serogroup B strains has not been confirmed.

U.S. Important Safety Information

TRUMENBA® (Meningococcal Group B Vaccine) should not be given to anyone with a history of a severe allergic reaction after a previous dose of TRUMENBA.

Individuals with weakened immune systems may have a reduced immune response.

The most common adverse reactions in adolescents and young adults were pain at the injection site, fatigue, headache, and muscle pain.

Data are not available on the safety and effectiveness of using TRUMENBA and other meningococcal group B vaccines interchangeably to complete the vaccination series.

Tell your healthcare provider if you are pregnant, or plan to become pregnant.

Ask your healthcare provider about the risks and benefits of TRUMENBA. Only a healthcare provider can decide if TRUMENBA is right for you or your child.

You are encouraged to report negative side effects of vaccines to the U.S. Food and Drug Administration (FDA) and the Centers for Disease Control and Prevention (CDC). Visit www.vaers.hhs.gov or call 1-800-822-7967.

About TRUMENBA® (Meningococcal Group B Vaccine)

TRUMENBA® (Meningococcal Group B Vaccine) was first introduced in the United States in October 2014 for active immunization to prevent invasive disease caused by Neisseria meningitidis serogroup B in individuals 10 through 25 years of age.

TRUMENBA is a sterile suspension composed of two recombinant lipidated factor H binding protein (fHBP) variants from N. meningitidis serogroup B, one from fHBP subfamily A and one from subfamily B (A05 and B01, respectively). fHBP is one of many proteins found on the surface of meningococci and contributes to the ability of the bacterium to avoid host defenses. fHBPs can be categorized into two immunologically distinct subfamilies, A and B.17 The susceptibility of serogroup B meningococci to complement-mediated, antibody-dependent killing following vaccination with TRUMENBA is dependent on both the antigenic similarity of the bacterial and vaccine fHBPs, as well as the amount of fHBP expressed on the surface of the invading meningococci.18

As with any vaccine, TRUMENBA may not prevent disease in all vaccinated individuals. The frequency of meningococcal disease caused by serogroup B varies geographically, and could influence the ability to evaluate effectiveness of the vaccine in any given country. Based on the low incidence of meningococcal disease, placebo-controlled clinical trials for TRUMENBA were considered unfeasible due to the size of the study that would be required and were not performed. Licensure of TRUMENBA was based on demonstration of immune responses measured using a serum bactericidal assay with human complement (hSBA).

About Meningococcal Disease

Meningococcal disease can affect anyone, at any age. The reported incidence of invasive meningococcal disease (IMD) varies by region, ranging from less than 0.5 cases per 100,000 in North America and just under 1 case per 100,000 in Europe, and up to 10-1,000 cases per 100,000 during epidemic years in Africa.19 The majority of invasive meningococcal disease cases worldwide can be attributed to six Neisseria meningitidis serogroups (A, B, C, W-135, X and Y).19 Together serogroups A, B, C, W-135, and Y account for 90% of all invasive meningococcal disease.14

Meningococcal disease can progress rapidly, and symptoms are difficult to distinguish from other more common infections, with flu-like symptoms such as headache, nausea and vomiting among the earliest signs.3 The most common clinical presentations of meningococcal disease are meningitis and septicemia.3
