ADZYNMA is a purified bivariant human recombinant “A disintegrin and metalloproteinase with thrombospondin motifs 13” (rADAMTS13) expressed in Chinese Hamster Ovary (CHO) cells using recombinant DNA technology (a mixture of Native rADAMTS13 Q23 and Variant rADAMTS13 R23 with a controlled range of the two variants ratio). ADZYNMA is produced and formulated without the addition of any exogenous raw materials of human or animal origin in the cell culture, purification, or formulation of the final product. The purification process for rADAMTS13 does not include use of a monoclonal antibody reagent. To enhance viral safety, the production process also incorporates two dedicated viral clearance steps – a solvent/detergent treatment step for inactivation and a 20 nm filtration step for removal of viruses. Recombinant ADAMTS13 has a molecular weight of approximately 172 kDa. Proteins that may be present in the final product, other than rADAMTS13, are trace quantities of host cell (CHO) proteins. ADZYNMA (rADAMTS13) is a sterile, nonpyrogenic, preservative free, white powder supplied in single-dose vials for IV use after reconstitution. Each single-dose vial contains nominally 500 IU or 1500 IU of rADAMTS13, sodium chloride (9.4 mg), calcium chloride dihydrate (1.6 mg), L-histidine (16.7 mg), mannitol (161.4 mg), sucrose (53.8 mg), and polysorbate 80 (2.7 mg). Each vial of ADZYNMA is labeled with the specific number of units of ADAMTS13 potency expressed in IU as measured with a fluorescence resonance energy transfer (FRET) assay using a synthetic 73-amino-acid peptide (FRETS-VWF73). The potency assignment employs an ADAMTS13 concentrate standard that is referenced to a WHO (World Health Organization) international standard for ADAMTS13 concentrates and is evaluated by appropriate methodology to ensure accuracy of the results. After reconstitution with 5 mL of Sterile Water for Injection, USP, the 500 IU and the 1500 IU vials result in a nominal potency of 100 IU/mL and 300 IU/mL, respectively. All dosage strengths yield a clear, colorless solution, free from particles with a pH of approximately 7.0.
