USFDA announced today the approval of Trumenba, the first vaccine licensed
in the United States to prevent invasive meningococcal disease caused by
Neisseria meningitidis serogroup B in individuals 10 through 25 years of age.
Meningococcal
disease is a life-threatening illness caused by bacteria that infect
the bloodstream (sepsis) and the lining that surrounds the brain and
spinal cord (meningitis). N. meningitidis is a leading cause of
bacterial meningitis. The bacteria are transmitted from person to person
through respiratory or throat secretions (e.g., by coughing, kissing,
or sharing eating utensils). According to the Centers for Disease
Control and Prevention, about 500 total cases of meningococcal disease
were reported in the United States in 2012; of those cases, 160 were
caused by serogroup B.
Meningococcal disease can be treated with antibiotics to reduce the risk
of death or serious long-term problems, but immediate medical attention
is extremely important. Vaccination is the most effective way to
prevent meningococcal disease. Until today, meningococcal vaccines
approved for use in the United States have only covered four of the five
main serogroups of N. meningitidis bacteria that cause meningococcal disease: A, C, Y, and W.
The FDA used the accelerated approval regulatory pathway to approve
Trumenba. Accelerated approval allows the agency to approve products for
serious or life-threatening diseases based on evidence of a product’s
effectiveness that is reasonably likely to predict clinical benefit,
reducing the time it takes for needed medical products to become
available to the public. In the FDA’s evaluation for accelerated
approval, evidence of effectiveness was demonstrated by the ability of
Trumenba recipients’ antibodies to kill the four representative N. meningitidis
serogroup B test strains. As part of the accelerated approval process,
the manufacturer will conduct further studies to verify Trumenba’s
effectiveness against additional strains of N. meningitidis serogroup B.
Trumenba
was granted breakthrough therapy status, which is intended to expedite
the development and review of medical products that address a serious or
life-threatening condition. Working closely with the company, the FDA
was able to evaluate Trumenba’s safety and effectiveness and approve it
in well under six months, the usual timeframe for a priority review.
Trumenba is manufactured by Wyeth Pharmaceuticals Inc., a subsidiary of Pfizer Inc., Philadelphia, Pennsylvania.
