What treatment with PALYNZIQ looks like

PALYNZIQ® (pegvaliase-pqpz) Injection is a daily at-home injectable treatment.

Here are a few things to know about how you will take PALYNZIQ:

  • You will give yourself daily injections just under the skin (subcutaneously) while at home
  • PALYNZIQ comes in prefilled syringes that can be injected in a few steps

PALYNZIQ is available in 3 dosage strengths:

PALYNZIQ uses a subcutaneous injection, which is inserted into the fatty tissue just under the layer of skin. It does not go as far into the body as an intramuscular injection.

Finding a dose to meet your treatment goals

Your clinic team will slowly adjust the dose of your PALYNZIQ to find a dose that works for you.

You will start by injecting PALYNZIQ once a week. Then, your healthcare provider will adjust your dose based on how you’re responding to therapy.

Here is an example of how dosing with PALYNZIQ may look:

Additional time may be required prior to each dosage escalation based on patient tolerability.

Individualize treatment to the lowest effective and tolerated dosage. Consider increasing to 40 mg once daily in patients who have not achieved a response with 20 mg once daily continuous treatment for at least 24 weeks. Consider increasing to a maximum of 60 mg once daily in patients who have not achieved a response with 40 mg once daily continuous treatment for at least 16 weeks.

PALYNZIQ should be discontinued if patients have not achieved an adequate response after 16 weeks of continuous treatment at the maximum dosage of 60 mg once daily.

 

Everyone responds differently to PALYNZIQ and finding the right dose for you will take time.

The reason PALYNZIQ is introduced slowly and over time is to allow your immune system to get used to the medication.

Overcoming Injection Fear
Ease your fear of needles and injections with a brief overview of the product education and support that you’ll receive with PALYNZIQ.

Before injecting PALYNZIQ, talk to your healthcare provider right away if you cannot or will not use auto-injectable epinephrine to treat a severe allergic reaction. If you are pregnant or plan to become pregnant while taking PALYNZIQ, talk to your healthcare provider to discuss the risks and benefits of taking PALYNZIQ during pregnancy to you and your unborn baby. If you are breastfeeding or plan to breastfeed, talk to your healthcare provider to discuss the risks and benefits of taking PALYNZIQ while breastfeeding for you and your baby.

 

You’re not alone—when you start taking PALYNZIQ, your clinic team will:

  • Show you how to properly inject PALYNZIQ
  • Be present as you give yourself your first injection
  • Confirm your ability to self-administer PALYNZIQ
  • Teach you about the signs and symptoms of anaphylaxis, and what to do if you have anaphylaxis
  • Instruct you on how to use auto-injectable epinephrine in case it’s needed due to anaphylaxis
    • You must carry your auto-injectable epinephrine with you at all times

Side effects can occur with PALYNZIQ

PALYNZIQ can cause a severe allergic reaction (anaphylaxis) that may be life threatening and can happen at any time during treatment with PALYNZIQ.

Your clinic team will train you to recognize the signs and symptoms so you’ll be ready and well-prepared to manage this reaction, should it occur. These include:

  • Fainting (passing out)
  • Dizziness or lightheadedness
  • Sudden confusion
  • Trouble breathing or wheezing
  • Chest discomfort or chest tightness
  • Fast heart rate
  • Swelling of your face, lips, eyes, or tongue
  • Throat tightness
  • Flushed skin
  • Skin rash, itching, or raised bumps on skin
  • Nausea, vomiting, or diarrhea
  • Losing control of urine or stools

10% of patients (29 of 285) experienced anaphylaxis in clinical studies

 
  • Of the 10% of patients who experienced anaphylaxis in PALYNZIQ studies, 72% of them were able to return to treatment with PALYNZIQ under the supervision of their clinic team
  • Of those patients who returned to treatment, the majority (71%) did not experience anaphylaxis again
  • All anaphylaxis episodes in the trial ended without further health consequences for the patients

For your safety, your clinic team will prescribe auto-injectable epinephrine. Keep the auto-injectable epinephrine with you at all times during treatment with PALYNZIQ.


Common side effects when patients in clinical studies were starting (induction) and increasing (titration) their PALYNZIQ dose (N=285).

About joint pain

While most patients taking PALYNZIQ experienced some form of joint pain, episodes went away after just over 2 weeks. Half (50%) of joint pain episodes lasted 3 days or fewer.

About injection site reactions

Injection site reactions can happen at any time when taking PALYNZIQ and typically go away within 10 days. Half (50%) of injection site reactions lasted 2 days or fewer.

 
  • During maintenance (ongoing), common side effects were similar to those seen when starting therapy and while increasing therapy
  • It’s also important to know that while most patients in clinical studies experienced a side effect while taking PALYNZIQ, only 15% of people stopped treatment due to side effects

Most side effects seen with PALYNZIQ in clinical studies were considered mild to moderate and generally decreased over time—many of which can be managed.
