1. What is Naglazyme and what is it used for

Naglazyme is used to treat patients with MPS VI (Mucopolysaccharidosis VI).

People with MPS VI have low or no levels of an enzyme called N-acetylgalactosamine 4-sulfatase that breaks down specific substances (glycosaminoglycans) in the body. As a result, these substances are not broken down and processed by the body as they should be. They accumulate in many tissues in the body, causing the symptoms of MPS VI.

HowNaglazyme works

This medicine contains a recombinant enzyme called galsulfase that can replace the natural enzyme that is missing in patients with MPS VI. It has been shown that treatment improves walking and stair-climbing ability, and reduces the levels of glycosaminoglycans in the body. This medicine may improve the symptoms of MPS VI.

Pregnancy and breastfeeding

This medicine has been authorised under “exceptional circumstances”.

This means that due to the rarity of your disease, it has not been possible to obtain complete information on this medicine.

The European Medicines Agency will review any new information that becomes available every year and this leaflet will be updated as necessary.

<-------------------------------------------------------------------------------------------------------------------------

This information is intended only for healthcare professionals:

Naglazyme should not be mixed with any other medicine in the same infusion, except for those mentioned below.

Each vial of Naglazyme is for single use. The concentrate for solution for infusion must be diluted with a sodium chloride 9 mg/ml (0.9%) solution for infusion using an aseptic technique. It is recommended that the diluted Naglazyme solution be administered to patients using an infusion set equipped with an in-line filter (0.2 μm).

Disposal of unused medicine and all materials that have come into contact with it should be done in accordance with local regulations.

Preparation of Naglazyme infusion (using 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 approximately 20 minutes before to allow them to reach room temperature.

Prior to dilution, each vial will be visually inspected for the presence of particles or color changes. The solution, which varies from transparent to slightly opalescent and from colorless to pale yellow, should be free of visible particles.

A volume of sodium chloride 9 mg/ml (0.9%) solution for infusion will be withdrawn from a 250 ml infusion bag and discarded, equal to the total volume of Naglazyme to be added. The use of 100 ml infusion bags may be considered in patients sensitive to fluid volume overload and weighing less than 20 kg; in such cases, the infusion rate (ml/min) will be reduced so that the total duration is not less than 4 hours. If 100 ml bags are used, the volume of Naglazyme may be added directly to the infusion bag.

The volume of Naglazyme will be added slowly to the sodium chloride 9 mg/ml (0.9%) solution for infusion.

The solution will be gently mixed for infusion.

The solution will be visually inspected for particles before use. Only clear and colorless solutions without visible particles should be used.
