(vestronidase alfa-vjbk) may work
MEPSEVII is a formulation of the GUS enzyme
It was shown in animal studies to regularly replace the missing GUS enzyme.
How MEPSEVII may work
MEPSEVII may help to restore cell function by replacing an enzyme that is missing in people with MPS VII. This process of replacing the missing or deficient enzyme is called enzyme replacement therapy (ERT).
All patients treated with MEPSEVII experienced a reduction in urinary GAGs, which was sustained with continued treatment
- A severe allergic reaction called anaphylaxis has occurred with MEPSEVII treatment, as early as the first dose.
- Your doctor will monitor you closely for symptoms of an allergic reaction while you are receiving MEPSEVII and for 60 minutes after your injection.
- Your doctor will immediately discontinue the MEPSEVII infusion if you experience anaphylaxis.
- Your doctor should talk to you about the signs and symptoms of anaphylaxis and about getting medical treatment if you have symptoms after leaving the doctor’s office or treatment center.
- The most common side effects of MEPSEVII are:
- Leakage of MEPSEVII into the surrounding tissue during infusion
- Severe allergic reaction (anaphylaxis)
- Infusion site swelling
- Swelling around the infusion site
- Severe itching of the skin
- One patient experienced a seizure during a fever while taking MEPSEVII.
- are pregnant, think you may be pregnant, or plan to become pregnant. There is not enough experience to know if MEPSEVII may harm your unborn baby.
- are breastfeeding or plan to breastfeed. There is not enough experience to know if MEPSEVII passes into your breast milk. Talk with your doctor about the best way to feed your baby while you receive MEPSEVII.
These are not all the possible side effects of MEPSEVII. Call your doctor for medical advice about side effects.
