Nexviazyme is a biologic therapy that is indicated to treat:

What Is Nexviazyme? 

Nexviazyme (avalglucosidase alfa-ngpt) is an enzyme replacement infusion therapy used for the treatment of patients 1 year of age and older with late-onset Pompe disease. 

How Nexviazyme Works  

Patients with late-onset Pompe disease (LOPD) lack or have a deficiency of the enzyme that breaks down glycogen in muscle cells, causing the glycogen to build up and result in muscle damage. 

Nexiazyme works by replacing the missing or deficient enzyme to bind to muscle cells and then enter the cells to help break down glycogen. 

What Is Nexviazyme Used For?  

Doctors order avalglucosidase alfa-ngpt to treat: 

  • Patients 1 year of age and older with late-onset Pompe disease. 

Nexviazyme Infusion Dosage and Administration  

Patients receive avalglucosidase alfa-ngpt intravenously. Treatment time for a Nexviazyme infusion at a medical clinic like IVX Health usually lasts between four and seven hours depending on dosage amount. 

Dosage and Frequency  

Before receiving their first intravenous infusion of avalglucosidase alfa-ngpt, the ordering physician determines the patient’s dose. This dose depends on the patient’s weight as well as the severity of the condition for which he or she is receiving treatment. 

Doses are typically administered once every two weeks. 

Administering Nexviazyme via IV Infusion  

  1. The nurse prepares the patient’s arm by using rubbing alcohol to sterilize the location that is being used to insert the IV needle. 
  2. Following needle insertion, the IV line is held in place with tape. 
  3. The nurse attaches the patient’s IV line to the line coming down from the bag of medication. 

Every half-an-hour, the patient’s nurse takes his or her vitals. 

Nexviazyme Infusion Side Effects  

As with all medications, side effects are possible. 

Common side effects include: 

  • Headache

  • Dizziness 
  • Muscle pain 
  • Itching

How To Prepare for a Nexviazyme Infusion

  • Have heart or lung issues 
  • Have an allergy to any of the ingredients in Nexviazyme

Before treatment, patients should get a good night’s sleep. In addition, they need to drink an adequate amount of fluid and eat a meal before their Nexviazyme IV infusion treatment at IVX Health.
