Tocilizumab-aazg is a recombinant humanized anti-human interleukin 6 (IL-6) receptor monoclonal antibody of the immunoglobulin IgG1 κ (gamma 1, kappa) subclass with a typical H 2 L 2 polypeptide structure. Each light chain and heavy chain consists of 214 and 448 amino acids (excluding the C-terminal lysine), respectively. The four polypeptide chains are linked intra- and inter-molecularly by disulfide bonds. Tocilizumab-aazg has a molecular weight of approximately 148 kDa. The antibody is produced in mammalian (Chinese hamster ovary) cells. Intravenous Infusion TYENNE (tocilizumab-aazg) injection is a sterile, clear and colorless to pale yellow, histidine buffered preservative-free solution with a pH of approximately 6 for further dilution prior to intravenous infusion. Each single-dose vial is available at a concentration of 20 mg/mL containing 80 mg/4 mL, 200 mg/10 mL, or 400 mg/20 mL of TYENNE. Each mL of solution contains arginine (17.4 mg), histidine (3.1 mg), lactic acid (0.9 mg), polysorbate 80 (0.2 mg), sodium chloride (0.6 mg), and Water for Injection, USP. Hydrochloric acid and sodium hydroxide are added to adjust the pH. Subcutaneous Injection TYENNE (tocilizumab-aazg) injection is a sterile, clear, colorless to pale yellow, preservative-free, histidine buffered solution with a pH of approximately 6 for subcutaneous use. It is supplied in a ready-to-use, single-dose 0.9 mL prefilled syringe (PFS) with a needle safety device or in a ready-to-use, single-dose 0.9 mL autoinjector that delivers 162 mg tocilizumab-aazg, arginine (16.7 mg), histidine (2.0 mg), lactic acid (0.9 mg), polysorbate 80 (0.2 mg), sodium chloride (0.6 mg), and Water for Injection, USP. Hydrochloric acid and sodium hydroxide are added to adjust the pH.
