1. What is Loargys and how is it used
Loargys contains the active ingredient pegzilarginase, which is a modified human enzyme produced by recombinant DNA technology. The medication is used to treat arginase 1 deficiency (ARG1-D), also known as hyperargininemia, in adults, adolescents, and children aged 2 years and older.
Patients with ARG1-D have low levels of an enzyme called arginase. This enzyme helps the body control arginine levels, an amino acid the body needs to produce proteins. If arginine is not controlled, it can accumulate in the body and cause symptoms, such as muscle control problems.
Loargys is used in combination with other forms of treatment. These may include:
- a low-protein diet
- food supplements with essential amino acids
- medications to treat other disease symptoms, such as medications that reduce ammonia levels in the body.
How Loargys works
The pegzilarginase, the active ingredient in Loargys, acts similarly to the natural arginase enzyme, which is lacking or not functioning correctly in patients with ARG1-D. This reduces blood arginine levels, thereby reducing disease symptoms.
2. What you need to know before starting Loargys
You should not receive Loargys
- if you have had a severe allergic reaction to pegzilarginase or any of the other components of this medication (listed in section6).
Warnings and precautions
Loargys may cause allergic reactions. This is more likely to occur after the first two doses.
Stop the injection immediately and contact your doctor or emergency services if you experience any of the following severe allergic reaction symptoms: hives, generalized itching, chest tightness, difficulty breathing, or low blood pressure. Your doctor may decide that you need additional medical treatment to prevent or treat an allergic reaction.
During your treatment, your doctor will perform blood tests to check what dose of Loargys is suitable for you.
Children and adolescents
The medication should not be used in children under 2 years of age, as it is not known if Loargys is safe and effective in this age group.

Inform your doctor if you are taking, have taken recently, or may need to take any other medication.

3. How Loargys is administered
Loargys will be administered by a healthcare professional. Your doctor will decide the amount of Loargys that you will receive.
The recommended initial dose of Loargys is 0.1 mg per kilogram of body weight, administered once a week. Your doctor may increase or decrease the dose to maintain arginine levels in the blood under control. Your doctor will prescribe periodic blood tests to check your arginine levels in the blood and adjust your dose as needed.
Loargys is administered through infusion (drip) directly into a vein or through subcutaneous injection, as your doctor considers appropriate.
Your doctor may decide that you can receive Loargys at home, in the form of a subcutaneous injection. After receiving training from your doctor or nurse, you may be able to administer Loargys yourself (see instructions in section7).
Always use this medication exactly as described in the present leaflet or as indicated by your doctor, pharmacist, or nurse. If in doubt, consult your doctor, pharmacist, or nurse.
If you receive more Loargys than you should
Your doctor will ensure that you receive the correct amount of Loargys. If you have received too much Loargys, your arginine level in the blood may become too low. Symptoms may include nausea, vomiting, diarrhea, and fatigue. If you or your doctor suspect that you have received more Loargys than you should, you will be closely monitored and receive the necessary treatment.
If you forget to use «Loargys»
If you have forgotten a dose of Loargys, contact your doctor to schedule the next dose as soon as possible. Do not receive a double dose to compensate for the missed doses, and at least 4 days should pass between doses.
If you interrupt treatment with Loargys
Your doctor will decide if you should stop using Loargys. If you stop treatment with Loargys, it is likely that your arginine level in the blood will increase again.
If you have any other questions about the use of this medication, ask your doctor or nurse.
