Full Consumer Medicine Information (CMI)
This leaflet provides important information about using QALSODY. You should also speak to your doctor or pharmacist if you would like further information
or if you have any concerns or questions about using QALSODY.
Where to find information in this leaflet:
1. Why am I using QALSODY?
2. What should I know before I use QALSODY?
1. Why am I being given QALSODY?
QALSODY contains the active ingredient tofersen.
QALSODY belongs to a group of medicines known as antisense oligonucleotides (ASOs).
QALSODY is used
in adults
to treat the type of amyotrophic lateral sclerosis (ALS) caused by an altered superoxide
dismutase 1 (SOD1) gene. This is a rare type of motor neuron disease.
The altered gene causes a build-up of toxic SOD1 protein. This causes loss of nerve
cells in the brain and spine, leading to weakness in muscles, including those used
for breathing and swallowing.
QALSODY works by reducing the build-up of SOD1 protein. This helps to prevent the
loss of nerve cells and may slow the loss of muscle strength.
2. What should I know before I am given QALSODY?
Warnings
Do not use QALSODY if:
you are allergic to tofersen, or any of the ingredients listed at the end of this
leaflet.
Always check the ingredients to make sure you can use this medicine.
Check with your doctor if you:
have any other medical conditions.
take any medicines for any other condition.
During treatment, you may be at risk of developing certain side effects. It is important
you understand these risks and how to monitor for them. See additional information
under Section
6. Are there any side effects?
Tests before treatment
You may have a urine test (to check your kidneys) and a blood test (to check that
your blood clots properly) before you start treatment. This is because other medicines
in the same group as QALSODY can affect the kidneys and the cells in the blood which
help clotting. These tests may not be needed every time you are given QALSODY.
Pregnancy and breastfeeding
If you are pregnant or breastfeeding, think you may be pregnant or are planning to
have a baby, ask your doctor for advice before you are given this medicine.
Pregnancy
QALSODY is not recommended to be used during pregnancy and in women of childbearing
potential not using contraception.
Breastfeeding
Your doctor will help you to decide whether you should continue breastfeeding or to
start treatment with QALSODY. Your doctor will consider the possible benefits of treatment
for you compared with the benefits of breastfeeding for your baby.
Children and adolescents
This medicine should not be given to children and adolescents under 18 years of age.
The use of this medicine in those under age 18 has not been studied.
3. What if I am taking other medicines?
Tell your doctor or pharmacist if you are taking any other medicines, including any
medicines, vitamins or supplements that you buy without a prescription from your pharmacy,
supermarket or health food shop.
Check with your doctor or pharmacist if you are not sure about what medicines, vitamins
or supplements you are taking and if these affect QALSODY.
4. How QALSODY is given?

How to use QALSODY
QALSODY is given by injection into the lower back. This injection, called a lumbar
puncture, is done by inserting a needle in the space around the spinal cord (intrathecal
space). This will be done by a doctor experienced in doing lumbar punctures.
If you miss a QALSODY injection
QALSODY should be used regularly. If you miss your dose at the usual time, speak to
your doctor so that it can be given as soon as possible.
If you are given too much QALSODY
No cases of overdose associated with QALSODY were reported in clinical trials.
Your doctor is trained to calculate the correct dose and administer your medicine.
If you think that you have been given too much QALSODY, you may need urgent medical
attention.
You should immediately:
phone the Poisons Information Centre
(by calling
13 11 26), or
contact your doctor, or
go to the Emergency Department at your nearest hospital.
You should do this even if there are no signs of discomfort or poisoning.
