Olipudase alfa-rpcp is a hydrolytic lysosomal sphingomyelin-specific enzyme consisting of 570 amino acids produced in a Chinese hamster ovary cell line by recombinant DNA technology. The molecular weight of olipudase alfa-rpcp is approximately 76 kDa. XENPOZYME (olipudase alfa-rpcp) for injection is supplied as a sterile, preservative-free, white to off-white lyophilized powder for reconstitution and dilution to be administered via intravenous infusion. XENPOZYME is supplied in single-dose vials. Each 4 mg vial contains 4 mg olipudase alfa-rpcp, dibasic sodium phosphate (0.89 mg), methionine (14.92 mg), monobasic sodium phosphate (1.63 mg), and sucrose (50 mg). After reconstitution with 1.1 mL of Sterile Water for Injection, USP, the final concentration is 4 mg/mL [see Dosage and Administration (2.6) ] . Each 20 mg vial contains 20 mg olipudase alfa-rpcp, dibasic sodium phosphate (4.47 mg), methionine (74.6 mg), monobasic sodium phosphate (8.17 mg), and sucrose (250 mg). After reconstitution with 5.1 mL of Sterile Water for Injection, USP, the final concentration is 4 mg/mL [see Dosage and Administration (2.6) ] . The pH is 6.5 after reconstitution.
