Trastuzumab-qyyp 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-qyyp is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture. TRAZIMERA (trastuzumab-qyyp) for injection is a sterile, white, preservative-free lyophilized powder with a cake-like appearance, for intravenous administration. Each multiple-dose vial of TRAZIMERA delivers 420 mg trastuzumab-qyyp, 7.9 mg L-histidine, 9.5 mg L-histidine HCl monohydrate, 1.7 mg polysorbate 20, and 386 mg sucrose. Reconstitution with 20 mL of the appropriate diluent (BWFI or SWFI) yields a solution containing 21 mg/mL trastuzumab-qyyp that delivers 20 mL (420 mg trastuzumab-qyyp), at a pH of approximately 6. If TRAZIMERA is reconstituted with SWFI without preservative, the reconstituted solution is considered single-dose. Each single-dose vial of TRAZIMERA delivers 150 mg trastuzumab-qyyp, 2.8 mg L-histidine, 3.4 mg L-histidine HCl monohydrate, 0.6 mg polysorbate 20, and 138 mg sucrose. Reconstitution with 7.4 mL of SWFI yields a solution containing 21 mg/mL trastuzumab-qyyp that delivers 7.15 mL (150 mg trastuzumab-qyyp), at a pH of approximately 6.
