SUMMARY

Novartis Vaccines and Diagnostics, Inc. is requesting licensure of Meningococcal (Groups A, C, W-135 and Y) Oligosaccharide CRM197 Conjugate Vaccine (Menveo®).  Menveo® is copackaged as a vial containing lyophilized MenA Conjugate Component and a vial ---(b)(4)-- containing the liquid MenCWY Conjugate Component.  The selected final formulation contains 10-5-5-5 µg per oligosaccharide of N. meningitides serogroups A, C, W135 and Y, respectively, without adjuvant.  The pharmaceutical form is a powder and a solvent for solution for injection.  The dose is 0.5 mL (after reconstitution).  Menveo® consists of four drug substances: Meningococcal group A oligosaccharide to Corynebacterium diphtheriae CRM197 protein (MenA-CRM Conjugate), Meningococcal group C oligosaccharide to Corynebacterium diphtheriae CRM197 protein (MenC-CRM Conjugate), Meningococcal group W-135 oligosaccharide to Corynebacterium diphtheriae CRM197 protein (MenW-CRM Conjugate), and Meningococcal group Y oligosaccharide to Corynebacterium diphtheriae CRM197 protein (MenY-CRM Conjugate).  Each drug substance is prepared from materials purified from two starting products of bacterial fermentation origin: Corynebacterium diphtheriae Cross Reactive Material 197 (CRM197) and capsular polysaccharide (A, C, W-135 and Y obtained from Neisseria meningitidis serogroups A, C, W-135 and Y, respectively).  There are a total of ----------b(4)--------------------------------------------------------------------------------------------------------
