1. What is Mepsevii and what is it used for
What is Mepsevii
Mepsevii contains a recombinant human enzyme called vestronidase alfa. This belongs to a group of medicines called "enzyme replacement therapies". It is given to adults and children of all ages with MPS VII to treat the non-neurological manifestations of the disease (mucopolysaccharidosis VII, also known as Sly syndrome).
What is MPS VII
MPS VII is a genetic inherited disease in which the body does not produce enough of an enzyme called beta-glucuronidase.
- This enzyme breaks down mucopolysaccharides, which are a type of sugar.
- Mucopolysaccharides are made by the body and help form bones, cartilage, skin, and tendons.
- These sugars are constantly being recycled: new ones are created and old ones are broken down.
- If there is not enough beta-glucuronidase, some of these sugars build up in cells, causing damage to the body.
How Mepsevii works
This medicine replaces beta-glucuronidase, helping to break down the sugars that build up in the tissues of people with MPS VII, preventing them from accumulating and causing symptoms of the disease.
- Treatment may improve some signs and symptoms of the disease, such as walking problems and fatigue.
If treatment is started in early childhood, it may slow down the progression of the disease and reduce permanent damage.
2. What you need to know before you receive Mepsevii
Do not receive Mepsevii
- if you are allergic to vestronidase alfa or any of the other ingredients of this medicine (listed in section 6).
Warnings and precautions
Talk to your doctor before receiving Mepsevii.
The effects of treatment with vestronidase alfa will be evaluated periodically, and if no clear benefits are seen (including stabilization of clinical manifestations of the disease), discontinuation of treatment will be considered. Stopping treatment may cause significant worsening of the patient's clinical condition.
You should know that administration of vestronidase alfa does not correct irreversible complications of the disease (e.g., bone deformities).
Examine the side effects
- You may experience a reaction to the administration of the drug known as "infusion reaction". This includes any side effect that occurs during infusion or the day after, including an allergic reaction (see section 4 "Possible side effects"). If you experience an infusion reaction, tell your doctor immediately.
- If you experience an allergic reaction during infusion, your doctor may slow down or stop the infusion. Your doctor may also give you other medicines to treat the allergic reaction, such as an antihistamine, a corticosteroid, or an antipyretic (a medicine that lowers fever).
Other symptoms you should examine
- If you experience neck or back pain, numbness in your arms or legs, or loss of control of sphincters, tell your doctor immediately.These symptoms could be signs of a disease caused by spinal cord compression.
Other medicines and Mepsevii
Tell your doctor if you are using, have recently used, or might use any other medicines.
