GSK’s meningitis B vaccine Bexsero receives Breakthrough Therapy Designation from US FDA for prevention of Invasive Meningococcal Disease in children 2-10 years of age

LONDON, UK I February 7, 2018 I GlaxoSmithKline plc (LSE/NYSE: GSK) today announced that it has received Breakthrough Therapy Designation from the U.S. Food and Drug Administration (FDA) for its meningitis B vaccine Bexsero [Meningococcal group B Vaccine (rDNA, component, adsorbed)] for the development of the vaccine in the prevention of Invasive Meningococcal Disease (IMD) caused by serogroup B in children 2-10 years of age.

Bexsero is the first vaccine in the world to receive the Breakthrough Therapy Designation (BTD) twice. In 2014, Bexsero received BTD for development in the prevention of IMD in individuals 10-25 years of age and was subsequently granted Accelerated Approval in January 2015.

GSK Vaccines Chief Scientist Rino Rappuoli, who spent more than 20 years developing Bexsero, said: “This designation emphasises the importance of tackling big scientific challenges like meningitis B and breaking new ground in disease prevention through approaches like reverse vaccinology. GSK is committed to the pursuit of innovative vaccines that help protect against serious diseases with significant unmet need.”

Breakthrough Therapy Designation is designed to expedite the development and review of drugs and vaccines that are intended to treat or prevent serious conditions and preliminary clinical evidence indicates that the drug or vaccine may demonstrate substantial improvement over available therapy on a clinically significant endpoint(s).1 Drugs and vaccines that receive Breakthrough Therapy Designation are eligible for all features of the FDA’s Fast Track designation, including more frequent communication with the FDA about the drug’s development plan and eligibility for Accelerated Approval and Priority Review, if relevant criteria are met.2 

GSK Vaccines Chief Medical Officer Dr Thomas Breuer said: “Thirty-five percent of all meningitis B cases in the US occur in children under 11 years old.3 This designation is an important step forward in meningococcal prevention and extending the protection provided by this vaccine to a vulnerable age group in the US. We look forward to continuing to work with regulators and public health partners to make this vaccine available for them.

About meningococcal serogroup B disease

Invasive meningococcal B disease is the leading cause of life-threatening meningitis in the industrialised world. Although not common, invasive meningococcal B disease develops rapidly, typically amongst previously healthy children and adolescents, and results in high morbidity and mortality. Initial symptoms can often resemble flu, making it difficult to diagnose. About one in 10 of those who contract the disease may die, even with appropriate treatment. Additionally, up to 20 percent of those who survive bacterial meningitis may suffer a major physical or neurological disability (limb loss, hearing loss or seizures).4,5
