efgartigimod alfa and hyaluronidase human recombinant - Generic Medications

VYVGART HYTRULO is a fixed-combination drug product containing efgartigimod alfa and hyaluronidase (human recombinant). Efgartigimod alfa, a neonatal Fc receptor blocker, is a human immunoglobulin G1 (IgG1) -derived Fc fragment (fragment, crystallized) of the za allotype, produced in Chinese hamster ovary (CHO) cells. The efgartigimod alfa Fc fragment is a homodimer consisting of two identical peptide chains each consisting of 227 amino acids linked together by two interchain disulfide bonds with affinity for FcRn. The molecular weight of efgartigimod alfa is approximately 54 kDa. Hyaluronidase (human recombinant) is an endoglycosidase used to increase the dispersion and absorption of co-administered drugs when administered subcutaneously. Hyaluronidase (human recombinant) is a glycosylated single-chain protein produced by Chinese hamster ovary cells containing a DNA plasmid encoding for a soluble fragment of human hyaluronidase (PH20). Hyaluronidase (human recombinant) has a molecular weight of approximately 61 kDa. VYVGART HYTRULO (efgartigimod alfa and hyaluronidase-qvfc) injection is a sterile, preservative free, yellowish, clear to opalescent solution supplied in a single-dose prefilled syringe or vial for subcutaneous injection. Each 5 mL single-dose prefilled syringe contains 1,000 mg of efgartigimod alfa and 10,000 units of hyaluronidase (human recombinant). Each mL contains 200 mg of efgartigimod alfa, 2,000 units of hyaluronidase (human recombinant) and arginine hydrochloride (10.5 mg), histidine (1.4 mg), L-histidine hydrochloride monohydrate (2.2 mg), methionine (1.5 mg), polysorbate 80 (0.4 mg), sodium chloride (4.1 mg), sucrose (20.5 mg), and Water for Injection, USP, at a pH of 6.0. Each 5.6 mL single-dose vial contains 1,008 mg of efgartigimod alfa and 11,200 units of hyaluronidase (human recombinant). Each mL contains 180 mg of efgartigimod alfa, 2,000 units of hyaluronidase (human recombinant) and - histidine (1.4 mg), L- histidine hydrochloride monohydrate (2.2 mg), methionine (1.5 mg), polysorbate 20 (0.4 mg), sodium chloride (5.8 mg), sucrose (20.5 mg), and Water for Injection, USP, at a pH of 6.0 or - arginine hydrochloride (10.5 mg), histidine (1.4 mg), L- histidine hydrochloride monohydrate (2.2 mg), methionine (1.5 mg), polysorbate 80 (0.4 mg), sodium chloride (4.1 mg), sucrose (20.5 mg), and Water for Injection, USP, at a pH of 6.0.
