Trastuzumab-pkrb 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-pkrb is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture. HERZUMA (trastuzumab-pkrb) 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 HERZUMA delivers 420 mg trastuzumab-pkrb, 839 mg α,α-trehalose dihydrate, 9.5 mg L-histidine HCl, 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-pkrb that delivers 20 mL (420 mg trastuzumab-pkrb), at a pH of approximately 6. If HERZUMA is reconstituted with SWFI without preservative, the reconstituted solution is considered single-dose. Each single-dose vial of HERZUMA delivers 150 mg trastuzumab-pkrb, 299.6 mg α,α-trehalose dihydrate, 3.4 mg L-histidine HCl, 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-pkrb that delivers 7.15 mL (150 mg trastuzumab-pkrb), at a pH of approximately 6.

Rituximab-abbs is a genetically engineered chimeric murine/human monoclonal IgG1 kappa antibody directed against the CD20 antigen. Rituximab-abbs has an approximate molecular weight of 145 kD. Rituximab-abbs is produced by mammalian cell (Chinese Hamster Ovary) suspension culture in a nutrient medium. TRUXIMA (rituximab-abbs) injection is a sterile, clear to opalescent, colorless to pale yellow, preservative-free solution for intravenous infusion. TRUXIMA is supplied at a concentration of 10 mg/mL in either 100 mg/10 mL or 500 mg/50 mL single-dose vials. Each mL of solution contains 10 mg rituximab-abbs, polysorbate 80 (0.7 mg), sodium chloride (9 mg), tri-sodium citrate dihydrate (7.35 mg), and Water for Injection, USP. The pH is 6.5.
