1. What is Voxzogo and what is it used for

What is Voxzogo

Voxzogo contains the active substance vosoritide. It is similar to a protein found in the body called C-type natriuretic peptide (CNP). Vosoritide is produced using recombinant technology, where modified bacteria are used to include the gene that produces the protein.

What Voxzogo is used for

This medicine is used to treat achondroplasia in patients aged 4 months and older whose bones are still growing. Achondroplasia is a genetic disorder that affects the growth of almost all bones in the body, including the bones of the skull, spine, arms, and legs, resulting in a significantly reduced height with a characteristic appearance.

This product is only indicated for achondroplasia caused by a mutation in the FGFR3 gene, confirmed by genetic testing.

How Voxzogo works

The active substance in Voxzogo works directly on the growth plates of the bones to promote the growth of new bone.

2. What you need to know before you or your child use Voxzogo

Do not use Voxzogo

• if you or your child are allergic to vosoritide or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before starting Voxzogo:

• if you or your child have significant heart or blood pressure problems;
• if you or your child are taking or have recently taken medicines to lower blood pressure.

If any of the above applies to you or your child, or if you are unsure, talk to your doctor before using Voxzogo.

Effects on blood pressure

Voxzogo may lower blood pressure. As a result, you may feel dizzy, tired, or nauseous. Usually, blood pressure returns to normal within 90 minutes after the Voxzogo injection. If these effects occur and are severe, tell your doctor.

Drinking plenty of fluids at the time of injection may reduce the likelihood of these effects. It is recommended that patients eat a snack and drink sufficient fluid (such as water, milk, or juice) about 30 minutes before the injection.

Children and adolescents

There is not enough information about the use of this medicine in children under 4 months, and therefore, its use is not recommended.

Other medicines and Voxzogo

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

Pregnancy and breastfeeding

If you or your daughter are receiving treatment with this medicine and you or your daughter are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

The use of this medicine is not recommended during pregnancy and breastfeeding.

Table 1: Single-dose volumes by body weight in ml and unit volumes (U)

You or your child should eat a snack and drink sufficient water, milk, or juice about 30 minutes before receiving the injection. This may reduce side effects such as dizziness, tiredness, or nausea.
