Dosing & Administering VPRIV
Before prescribing or administering VPRIV, please read the Full Prescribing Information and safety details. A typical administration of VPRIV includes a 60-minute IV infusion every other week.1
The recommended starting dose for treatment-naïve patients 4 years of age and older is 60 U/kg. Patients 4 years of age and older currently being treated on a stable dosage of imiglucerase for type 1 Gaucher disease may be switched to VPRIV by starting treatment with VPRIV at the previous imiglucerase dosage 2 weeks after the last imiglucerase dose.1
- VPRIV should be administered under the supervision of a healthcare professional1
- Dosage adjustments can be made on an individual basis, based on achievement and maintenance of therapeutic goals1
- Clinical studies have evaluated doses ranging from 15 U/kg to 60 U/kg every other week. The recommended dosage is 60 U/kg administered every other week as a 60-minute IV infusion1
- No routine requirement for pretreatment medication in clinical trials

Important Safety Information
Hypersensitivity reactions, including anaphylaxis have occurred. The most serious adverse reactions in patients treated with VPRIV (velaglucerase alfa for injection) were hypersensitivity reactions.
Hypersensitivity reactions were the most commonly observed adverse reactions in patients treated with VPRIV in clinical studies. Patients were not routinely pre-medicated prior to infusion of VPRIV. The most commonly observed symptoms of hypersensitivity reactions were: headache, dizziness, hypotension, hypertension, nausea, fatigue/asthenia, and pyrexia. Hypersensitivity reactions in the clinical trials include any event considered related to and occurring within up to 24 hours of VPRIV infusion, including one case of anaphylaxis. Generally the reactions were mild and, in treatment-naïve patients, onset occurred mostly during the first 6 months of treatment and tended to occur less frequently with time.
As with any intravenous protein product, hypersensitivity reactions are possible, therefore appropriate medical support, including personnel adequately trained in cardiopulmonary resuscitative measures and access to emergency measures should be readily available when VPRIV is administered. If anaphylactic or other acute reactions occur, immediately discontinue the infusion of VPRIV and initiate the appropriate medical treatment.
Management of hypersensitivity reactions should be based on severity of the reaction, such as slowing the infusion rate, treatment with medications such as antihistamines, antipyretics and/or corticosteroids, and/or stopping and resuming treatment with increased infusion time. In cases where patients have exhibited symptoms of hypersensitivity to the active ingredient or excipients in the drug product or to other enzyme replacement therapy, pre-treatment with antihistamines and/or corticosteroids may prevent subsequent reactions.
The most common adverse reactions during clinical studies (in ≥10% of patients) were hypersensitivity reactions, headache, dizziness, abdominal pain, nausea, back pain, joint pain, prolonged activated PTT, fatigue/asthenia, and pyrexia. In clinical studies, the overall frequency of adverse events was generally higher in the population naïve to ERT (enzyme replacement therapy) than in the population switched from imiglucerase to VPRIV.
VPRIV is classified as pregnancy category B.
The safety and efficacy profiles were similar in pediatric (ages 4 to 17) and adult patients. The safety of VPRIV has not been established in patients under 4 years of age. Adverse reactions more commonly seen in pediatric patients compared to adult patients include (>10% difference): rash, aPTT prolonged, and pyrexia.
The adverse reaction profile in elderly patients was consistent with that previously observed across pediatric and adult patients. In general, dose selection for an elderly patient should be approached cautiously, considering comorbid conditions.
As with all therapeutic proteins, there is a potential for immunogenicity. In clinical studies, 1 of 54 enzyme treatment-naïve patients treated with VPRIV developed IgG class antibodies (neutralizing in an in vitro assay). It is unknown if the presence of IgG antibodies to VPRIV is associated with a higher risk of infusion reactions. Patients with an immune response to other enzyme replacement therapies who are switching to VPRIV should continue to be monitored for antibodies to VPRIV.
