Trumenba is a sterile suspension composed of two recombinant lipidated factor H binding protein (fHbp) variants from N. meningitidis serogroup B, one from fHbp subfamily A and one from subfamily B (A05 and B01, respectively).1 The proteins are individually produced in E. coli. Production strains are grown in defined fermentation growth media to a specific density. The recombinant proteins are extracted from the production strains and purified through a series of column chromatography steps. Polysorbate 80 (PS80) is added to the drug substances and is present in the final drug product.
Each 0.5 mL dose contains 60 micrograms of each fHbp variant (total of 120 micrograms of protein), 0.018 mg of PS80 and 0.25 mg of Al3+ as AlPO4 in 10 mM histidine buffered saline at pH 6.0.
