1. What Lamzede is and what it is used for

Lamzede contains the active substance velmanase alfa which belongs to a group of medicines known as enzyme replacement therapies. It is used to treat patients with mild to moderate alpha-mannosidosis disease. It is given for the treatment of non-neurological symptoms of the disease.

Alpha-mannosidosis disease is a rare genetic disorder caused by a lack of an enzyme named alpha-mannosidase, which is needed to break down certain sugar compounds (called ‘mannose‑rich oligosaccharides’) in the body. When this enzyme is missing or does not work properly, these sugar compounds build up inside cells and cause the signs and symptoms of the disease. The typical manifestations of the disease include distinctive facial features, mental retardation, difficulty in controlling movements, difficulties in hearing and speaking, frequent infections, skeletal problems, muscle pain and weakness.

Velmanase alfa is designed to replace the missing enzyme, in patients with alpha-mannosidosis disease.

2. What you need to know before you use Lamzede
Do not use Lamzede:
  • if you are allergic to velmanase alfa or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before Lamzede is used.

Hypersensitivity reactions may occur with the administration of Lamzede. These reactions usually appear during or soon after the infusion and may manifest with several symptoms, such as localised or diffuse skin reactions, gastrointestinal symptoms or swelling of the throat, face, lips or tongue (see section 4 “Possible side effects”). If the hypersensitivity reaction is severe, immediate discontinuation of Lamzede is recommended and current medical standards for emergency treatment are to be followed. Less severe hypersensitivity reactions may be managed by temporary interruption of the infusion or by slowing down infusion rate; administration of medicines used to treat allergy may be considered by the physician.

If you are treated with Lamzede, you may experience a side effect during or immediately following the drip (infusion) used to give the medicine (see section 4 “Possible side effects”). This is known as an infusion-related reaction and can sometimes be severe.

  • Your doctor may decide to keep you under observation for one hour or longer after the infusion in relation to the infusion related reactions.
  • Infusion-related reactions include dizziness, headache, nausea, low or high blood pressure, tiredness and fever. If you experience an infusion-related reaction, you must tell your doctor immediately.
  • If you have an infusion-related reaction you may be given additional medicines to treat or help prevent future reactions. These medicines may include medicines used to treat allergies (antihistamines), medicines used to treat fever (antipyretics) and medicines to control inflammation (corticosteroids).
  • If the infusion-related reaction is severe, your doctor will stop the infusion immediately and start giving you appropriate medical treatment.
  • If the infusion-related reactions are severe and/or there is a loss of effect from this medicine, your doctor will perform a blood test to check for antibodies that might affect the outcome of your treatment.
  • Most of the time you can still be given Lamzede even if you experience an infusion-related reaction.

Antibodies may play a role in hypersensitivity and infusion related reactions observed with the use of Lamzede.

Although 24% of patients developed antibodies against Lamzede during its clinical development, no clear correlation was found between antibody titres and reduction in efficacy or occurrence of hypersensitivity reactions.

Other medicines and Lamzede

Tell your doctor if you are taking, have recently taken or might take any other medicines.

Pregnancy and breast-feeding

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor for advice before this medicine is used.

You should not take this medicine during pregnancy unless your doctor states it is clearly necessary. Your doctor will discuss that with you.

It is not known whether velmanase alfa passes into breast milk. Lamzede can be used during breast-feeding since the velmanase alfa will not be absorbed by a breast-fed child.

Driving and using machines

Lamzede has no or negligible influence on the ability to drive and use machines.

Lamzede contains sodium

This medicine contains less than 1 mmol sodium (23 mg) per dose unit, that is to say essentially ‘sodium-free’.

3. How to use Lamzede

This medicine is only to be used under the supervision of a doctor experienced in the treatment of alpha-mannosidosis or other similar diseases and should only be given by a healthcare professional.

Lamzede is only used under the supervision of a doctor who is knowledgeable in the treatment of Alpha Mannosidosis disease. Your doctor may advise that you can be treated at home provided you meet certain criteria. Please contact your doctor if you would like to be treated at home.


The recommended dose of Lamzede is 1 mg/kg of body weight given once every week.

Use in children and adolescents

Lamzede may be given to children and adolescents at the same dose and frequency as in adults.


Lamzede is supplied in a vial as a powder for infusion which will be made up with water for injections before being given. Once it has been made up, the medicine will be given by infusion pump (drip) into a vein over a period of at least 50 minutes under your doctor’s supervision.

If you have any further questions on the use of this medicine, ask your doctor, nurse or pharmacist.
