Other Information
The active ingredient of VPRIV is velaglucerase alfa, which is produced by gene activation technology in a human fibroblast cell line. Velaglucerase alfa is a glycoprotein of 497 amino acids; with a molecular weight of approximately 63 kDa. Velaglucerase alfa has the same amino acid sequence as the naturally occurring human enzyme, glucocerebrosidase. Velaglucerase alfa contains 5 potential N-linked glycosylation sites; four of these sites are occupied by glycan chains. Velaglucerase alfa contains predominantly high mannose-type N-linked glycan chains. The high mannose type N-linked glycan chains are specifically recognized and internalized via the mannose receptor present on the surface on macrophages, the cells that accumulate glucocerebroside in Gaucher disease. Velaglucerase alfa catalyzes the hydrolysis of the glycolipid glucocerebroside to glucose and ceramide in the lysosome.
VPRIV is a hydrolytic lysosomal glucocerebroside-specific enzyme. VPRIV is dosed by Units/kg, where one Unit of enzyme activity is defined as the quantity of enzyme required to convert one micromole of p-nitrophenyl ß-D-glucopyranoside to p-nitrophenol per minute at 37°C.
VPRIV is supplied as a sterile, preservative free, lyophilized powder in single-use vials, each containing 400 Units, for intravenous use. Following reconstitution with Sterile Water for Injection, USP, the solution contains the components listed in Table 2.

2.1 Dosing InformationThe maximum single recommended adult dose of Sumatriptan Succinate Injection for the acute treatment of migraine or cluster headache is 6 mg injected subcutaneously. For the treatment of migraine, if side effects are dose limiting, lower doses (1 mg to 5 mg) may be used [see Clinical Studies (14.1)]. For the treatment of cluster headache, the efficacy of lower doses has not been established.
The maximum cumulative dose that may be given in 24 hours is 12 mg, two 6-mg injections separated by at least 1 hour. A second 6-mg dose should only be considered if some response to a first injection was observed.
2.2 Administration Using the Autoinjector PenAn autoinjector device is available for use with 4- mg and 6-mg prefilled syringe cartridges. With this device, the needle penetrates approximately 1/4 inch (5 to 6 mm). The injection is intended to be given subcutaneously, and intramuscular or intravascular delivery must be avoided. Instruct patients on the proper use of the autoinjector pen and direct them to use injection sites with an adequate skin and subcutaneous thickness to accommodate the length of the needle.
2.3 Administration of Doses of Sumatriptan Succinate Other than 4 or 6 mgIn patients receiving doses other than 4 mg or 6 mg, use the 6-mg single-dose vial; do not use the autoinjector pen. Visually inspect the vial for particulate matter and discoloration before administration. Do not use if particulates and discolorations are noted.
