VPRIV® (velaglucerase alfa for injection) is a hydrolytic lysosomal glucocerebroside-specific enzyme indicated for long-term enzyme replacement therapy (ERT) for pediatric and adult patients with type 1 Gaucher disease.
Important Safety Information
The most serious adverse reactions in patients treated with VPRIV were hypersensitivity reactions. Appropriate medical support should be available when VPRIV is administered. If a severe reaction occurs, medical standards for emergency treatment are to be followed.
Treatment with VPRIV should be used with caution in patients who have exhibited symptoms of hypersensitivity to the active ingredient, drug product excipients, or to other enzyme replacement therapies.
Infusion-related reactions were the most commonly observed adverse reactions in patients treated with VPRIV in clinical studies. The most commonly observed symptoms of infusion-related reactions were: headache, dizziness, hypotension, hypertension, nausea, asthenia/fatigue, and pyrexia. Generally the infusion-related 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.
Management of infusion-related 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.
Other commonly observed adverse reactions in ≥10% of ERT-naïve or imiglucerase-switched patients were: headache, dizziness, abdominal pain, nausea, back pain, joint pain, upper respiratory tract infection, activated PTT prolonged, infusion-related reactions, pyrexia, and asthenia/fatigue.
All adult adverse reactions to VPRIV are considered relevant to pediatric patients (ages 4 to 17 years). Adverse reactions more common in pediatric patients (>10% difference) included upper respiratory tract infection, rash, aPTT prolonged, and pyrexia. The safety of VPRIV has not been established in pediatric patients younger than 4 years of age.
As with all therapeutic proteins, there is a potential for immunogenicity. In clinical studies, 1 of 54 treatment-naïve patients treated with VPRIV (who received a 45 Units/kg dose) 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.
