1. What is Vimizim and what is it used for
Vimizim contains an enzyme called elosulfase alfa which belongs to a group of medicines known as enzyme replacement therapies. It is used to treat adults and children with mucopolysaccharidosis type IVA (MPS IVA disease, also known as Morquio A syndrome).
People with MPS IVA disease either completely lack or have very low levels of N-acetylgalactosamine-6-sulfatase, an enzyme that breaks down certain substances in the body, such as keratan sulfate, which are found in many tissues of the body, including cartilage and bone. As a result, these substances are not broken down or processed by the body as they should be. They build up in tissues, interfere with their normal function, and cause the symptoms of MPS IVA, such as difficulty walking, breathing problems, short stature, and hearing loss.
How Vimizim works
This medicine replaces the natural enzyme N-acetylgalactosamine-6-sulfatase that is lacking in patients with MPS IVA. It has been shown that treatment improves walking ability and reduces the levels of keratan sulfate in the body. This medicine may improve the symptoms of MPS IVA.

This information is intended only for healthcare professionals:
Vimizim should not be mixed with any other medicine in the same infusion, except for those mentioned below.
Each vial of Vimizim is for single use. Vimizim must be diluted with a 9 mg/ml (0.9%) sodium chloride solution for infusion using an aseptic technique. The diluted Vimizim solution should be administered to patients using an infusion set. An infusion set equipped with an in-line filter (0.2 μm) may be used.
Disposal of unused product and all materials that have come into contact with it should be in accordance with local requirements.
Preparation of Vimizim infusion (using an aseptic technique)
- The number of vials to be diluted will be determined based on the patient’s weight and will be removed from the refrigerator in advance to allow them to reach 23°C – 27°C. Do not heat the vials or place them in the microwave. The recommended dose is 2 mg/kg body weight administered once a week through a vein (intravenous infusion). Each infusion requires approximately 4 hours.
- Patient weight (kg) multiplied by 2 (mg/kg) = Patient dose (mg).
- Patient dose (mg) divided by 1 (mg/ml of Vimizim concentrate) = Total number of ml of Vimizim
- Total amount (ml) of Vimizim divided by 5 ml per vial = Total number of vials
- The total number of vials calculated should be rounded up to the next whole vial.
- Obtain an infusion bag containing 9 mg/ml (0.9%) sodium chloride solution for infusion suitable for intravenous administration. The total infusion volume will be determined based on the patient’s body weight.
- Patients weighing less than 25 kg should receive a total volume of 100 ml.
- Patients weighing 25 kg or more should receive a total volume of 250 ml.
- Before dilution, each vial should be inspected for particles and color changes. The clear to slightly opalescent and colorless to pale yellow solution should not contain visible particles. Do not shake the vials.
- Remove and discard a volume of the 9 mg/ml (0.9%) sodium chloride solution for infusion from a 100 ml or 250 ml infusion bag equivalent to the total volume of Vimizim to be added.
- Slowly withdraw the calculated volume of Vimizim from the appropriate number of vials, taking care to avoid excessive agitation.
- Slowly add the volume of Vimizim to the 9 mg/ml (0.9%) sodium chloride solution for infusion.
When diluted with 100 ml of 9 mg/ml (0.9%) sodium chloride solution for infusion:the initial rate will be 3 ml/h. The infusion rate will be increased every 15 minutes as follows: first increase the rate to 6 ml/h, then increase the rate every 15 minutes in increments of 6 ml/h until a maximum rate of 36 ml/h is reached.
When diluted with 250 ml of 9 mg/ml (0.9%) sodium chloride solution for infusion:the initial rate will be 6 ml/h. The infusion rate will be increased every 15 minutes as follows: first increase the rate to 12 ml/h, then increase the rate every 15 minutes in increments of 12 ml/h until a maximum rate of 72 ml/h is reached.
