Trastuzumab-anns 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-anns is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture containing the antibiotic geneticin. Geneticin is not detectable in the final product. KANJINTI (trastuzumab-anns) for injection is a sterile, white to pale yellow, preservative-free lyophilized powder with a cake-like appearance, for intravenous administration. Each multiple-dose vial of KANJINTI delivers 420 mg trastuzumab-anns, 381.8 mg α,α-trehalose dihydrate, 9.5 mg L-histidine HCl monohydrate, 6.1 mg L-histidine, and 1.7 mg polysorbate 20. Reconstitution with 20 mL of the appropriate diluent (BWFI or SWFI) yields a solution containing 21 mg/mL trastuzumab-anns that delivers 20 mL (420 mg trastuzumab-anns), at a pH of approximately 6. If KANJINTI is reconstituted with SWFI without preservative, the reconstituted solution is considered single-dose. Each single-dose vial of KANJINTI delivers 150 mg trastuzumab-anns, 136.2 mg α,α-trehalose dihydrate, 3.4 mg L-histidine HCl monohydrate, 2.2 mg L-histidine, and 0.6 mg polysorbate 20. Reconstitution with 7.4 mL of Sterile Water for Injection (SWFI) yields a solution containing 21 mg/mL trastuzumab-anns that delivers 7.15 mL (150 mg trastuzumab-anns), at a pH of approximately 6.
