The US Centers for Disease Control and Prevention (CDC) has issued a Health Advisory to let providers know that patients receiving Eculizumab (Soliris®) are at a high risk for invasive meningococcal disease despite vaccination.

Eculizumab is most commonly prescribed for treatment of 2 rare blood disorders: atypical hemolytic uremic syndrome (aHUS) and paroxysmal nocturnal hemoglobinuria (PNH). Through a request for data on meningococcal disease cases reported to state health departments, the CDC identified 16 cases of meningococcal disease in eculizumab recipients in the United States from 2008 through 2016; 11 (69%) of these were caused by nongroupable N. meningitidis. Meningococcal conjugate (MenACWY) vaccine targets serogroups A, C, W, and Y, and provides no protection against nongroupable N. meningitidis. Serogroup B meningococcal (MenB) vaccines are licensed specifically for protection against serogroup B meningococcal disease. Researchers have not assessed the extent of any potential cross protection for nongroupable N. meningitidis strains.

According to the CDC,

  • Eculizumab (Soliris®) recipients have a 1,000 to 2,000-fold greater risk of invasive meningococcal disease compared to the general U.S. population.
  • The Food and Drug Administration (FDA)-approved prescribing information for eculizumab includes a black box warning for increased risk of meningococcal disease, and the Advisory Committee on Immunization Practices (ACIP) recommends meningococcal vaccination for all patients receiving eculizumab.
  • Recent data show that some patients receiving eculizumab who were vaccinated with the recommended meningococcal vaccines still developed meningococcal disease, most often from nongroupable Neisseria meningitidis, which rarely causes invasive disease in healthy individuals.

Recommendations for Healthcare Providers:

  • Could consider antimicrobial prophylaxis for the duration of eculizumab therapy to potentially reduce the risk of meningococcal disease.
  • Should continue meningococcal vaccination of all patients who receive eculizumab.
  • Should administer meningococcal vaccines at least 2 weeks prior to administering the first dose of eculizumab, unless the risks of delaying eculizumab therapy outweigh the risks of developing a meningococcal infection, according to the product label.
  • Should maintain a high index of suspicion for meningococcal disease in patients taking eculizumab who present with any symptoms consistent with either meningitis or meningococcemia, even if the patient’s symptoms initially appear mild, and irrespective of the patient’s meningococcal vaccine or antimicrobial prophylaxis status.
