Trastuzumab-dkst is a humanized IgG1 kappa monoclonal antibody that selectively binds with high affinity to the extracellular domain of the human epidermal growth factor receptor 2 protein, HER2. Trastuzumab-dkst is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture. Ogivri (trastuzumab-dkst) for injection is a sterile, off-white to pale yellow, preservative-free lyophilized powder with a cake-like appearance, for injection, for intravenous administration. Each multiple-dose vial of Ogivri delivers 420 mg trastuzumab-dkst, D-sorbitol (322.6 mg), L-Histidine (6.0 mg), Histidine hydrochloride monohydrate (9.4 mg) and Polyethylene glycol 3350/Macrogol 3350 (94.1 mg). Hydrochloric acid or sodium hydroxide may be used to adjust the pH of the formulation buffer. Reconstitution with 20 mL of the appropriate diluent (BWFI or SWFI) yields a solution containing 21 mg/mL trastuzumab-dkst that delivers 20 mL (420 mg trastuzumab-dkst), at a pH of approximately 6. If Ogivri is reconstituted with SWFI without preservative, the reconstituted solution is considered single-dose. Each single-dose vial of Ogivri delivers 150 mg trastuzumab-dkst, D-sorbitol (115.2 mg), L-Histidine (2.16 mg), L-Histidine hydrochloride monohydrate (3.36 mg) and Polyethylene glycol 3350/Macrogol 3350 (33.6 mg). Hydrochloric acid or sodium hydroxide may be used to adjust the pH of the formulation buffer. Reconstitution with 7.4 mL of sterile water for injection (SWFI) yields a solution containing 21 mg/mL trastuzumab-dkst that delivers 7.15 mL (150 mg trastuzumab-dkst), at a pH of approximately 6.
