herceptin hylecta - Medication Listings

HERCEPTIN HYLECTA is a combination of trastuzumab and hyaluronidase. Trastuzumab 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 is produced by recombinant DNA technology in a mammalian cell (Chinese Hamster Ovary) culture. Trastuzumab has a molecular weight of approximately 148 kDa. Hyaluronidase (recombinant human) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. It is a glycosylated single-chain protein produced by mammalian (Chinese Hamster Ovary) cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase (recombinant human) has a molecular weight of approximately 61 kDa. HERCEPTIN HYLECTA (trastuzumab and hyaluronidase) injection is a sterile, preservative-free, colorless to yellowish, clear to opalescent solution supplied in single-dose vials for subcutaneous administration. HERCEPTIN HYLECTA is supplied as 600 mg trastuzumab and 10,000 units hyaluronidase per 5 mL in single-dose vials. Each mL of solution contains trastuzumab (120 mg), hyaluronidase (2,000 units), L-histidine (0.39 mg), L-histidine hydrochloride monohydrate (3.67 mg), L-methionine (1.49 mg), polysorbate 20 (0.4 mg), α,α-trehalose dihydrate (79.45 mg), and Water for Injection.
