cerliponase alfa - Generic Medications

Cerliponase alfa is a purified human enzyme produced by recombinant DNA technology in a Chinese hamster ovary cell line. The active substance is a recombinant human tripeptidyl peptidase-1 (rhTPP1), a lysosomal exopeptidase. The primary activity of the mature enzyme is the cleavage of N-terminal tripeptides from a broad range of protein substrates. Cerliponase alfa contains 544 amino acids with an average molecular mass of 59 kDa. The mature enzyme is 368 amino acids in length. There are 5 consensus N-glycosylation sites on rhTPP1 that contain high mannose, phosphorylated high mannose and complex glycosylation structures. BRINEURA (cerliponase alfa) Injection and Intraventricular Electrolytes Injection are administered by intraventricular infusion. The solutions are sterile, nonpyrogenic, and free of foreign particulates. BRINEURA is a clear to slightly opalescent and colorless to pale yellow solution. Intraventricular Electrolytes is a clear to colorless solution. BRINEURA and Intraventricular Electrolytes Injection are packaged in 10 mL clear Type 1 single-dose glass vials [see How Supplied/Storage and Handling (16) ]. Each vial of BRINEURA provides 5 mL of solution containing 150 mg cerliponase alfa. Each vial of Intraventricular Electrolytes Injection provides 5 mL of solution. Both BRINEURA and Intraventricular Electrolytes Injection are formulated with the following excipients: calcium chloride dihydrate (1.05 mg); magnesium chloride hexahydrate (0.8 mg); potassium chloride (1.1 mg); sodium chloride (43.85 mg); sodium phosphate, dibasic, heptahydrate (0.55 mg); sodium phosphate, monobasic, monohydrate (0.4 mg); and Water for Injection, USP. The pH of the solution is between 6.2 to 6.8 for BRINEURA, and between 6.0 to 7.0 for Intraventricular Electrolytes Injection. Each vial contains: sodium: 0.76 mEq, and potassium: 0.015 mEq.
