PENBRAYA™ Description

(meningococcal groups A, B, C, W, and Y vaccine)

11 DESCRIPTION

PENBRAYA (Meningococcal Groups A, B, C, W, and Y Vaccine) is a suspension for intramuscular injection. PENBRAYA is supplied as a sterile Lyophilized MenACWY Component to be reconstituted with the sterile MenB Component.

The Lyophilized MenACWY Component consists of N. meningitidis serogroups A, C, W, and Y polysaccharides individually conjugated to TT. The polysaccharide for each group is grown in media containing dextrose, salt, and yeast extract, then purified by precipitation and filtration. The TT is produced by fermentation of Clostridium tetani in dextrose, salts, and tryptone N1 peptone followed by formalin detoxification, then purified by a series of physicochemical steps. The serogroups A and C polysaccharides are individually microfluidized, activated with 1-cyano-4(dimethylamino)-pyridinium tetrafluorobate (CDAP), derivatized with adipic acid dihydrazide (ADH), and then conjugated with TT in the presence of 1-ethyl-3-(3-dimethylaminopropyl)carbodiimide) (EDAC). The serogroups W and Y polysaccharides are individually microfluidized, activated with CDAP, and then conjugated with TT. The conjugates are purified by a series of physicochemical steps then sterile filtered. Trometamol/sucrose buffer is added, and the MenACWY-TT solution is lyophilized.

The MenB Component is a sterile suspension composed of 2 recombinant lipidated factor H binding protein (fHbp) variants from N. meningitidis serogroup B, 1 from fHbp subfamily A and 1 from fHbp subfamily B (A05 and B01, respectively). The proteins are individually produced in Escherichia coli. Production strains are grown to a specific density in chemically defined fermentation growth media without antibiotics or animal-derived components. The recombinant proteins are extracted from the production strains and purified through a series of column chromatography steps. Polysorbate 80 (PS80) is added and is present in the MenB Component.

Each approximately 0.5 mL dose of PENBRAYA contains N. meningitidis serogroup A, C, W, and Y polysaccharide (5 mcg each; 20 mcg total) conjugated to tetanus toxoid (44 mcg tetanus toxoid), 2 recombinant lipidated factor H binding protein variants from N. meningitidis serogroup B (60 mcg each; total of 120 mcg protein), L-histidine (0.78 mg) , trometamol (0.097 mg), sucrose (28 mg), aluminum phosphate (0.25 mg aluminum), sodium chloride (4.65 mg), and PS80 80 (0.018 mg) at pH 6.0.

PENBRAYA does not contain any preservatives.
