EU approves expanded indication for Nimenrix (meningococcal group A, C, W-135, and Y conjugate vaccine) against meningococcal disease- Pfizer

Pfizer announced the European Commission (EC) has approved an expanded indication for Nimenrix (meningococcal group A, C, W-135, and Y conjugate vaccine) for active immunization against invasive meningococcal disease (IMD) caused by Neisseria meningitidis serogroups A, C, W-135, and Y (MenACWY) in infants as early as six weeks of age. Nimenrix is now the first and only MenACWY conjugate vaccine in the European Union (EU) that can be administered from six weeks of age with no upper age limit.

The EU approval is based upon results from a Phase III, open-label, randomized, controlled study (study MenACWY-TT-083) in which the immunogenicity and safety of Nimenrix was evaluated in over 1,000 healthy infants from six weeks of age. Based on clinical evidence, Nimenrix was approved for administration in infants as a two dose primary series, with the first dose given from six weeks of age and with an interval of two months between doses, followed by a booster dose at 12 months. The six confirmatory co-primary objectives of the study were met.
