How Long Does Vyvgart® Last?

If you’re living with generalized myasthenia gravis, you may look fine on the outside, but inside, you could be struggling to pick up everyday items, walk, or even breathe or swallow normally.

If you’re living with generalized myasthenia gravis, you may look fine on the outside, but inside, you could be struggling to pick up everyday items, walk, or even breathe or swallow normally.

However, according to an Argenx study, 68% of patients who added Vyvgart® (efgartigimod alfa-fcab) infusion treatments to their current oral gMG medication saw significant improvement in their ability to perform daily living activities. What is the treatment cycle like, and how long can you expect the relief from Vyvgart to last?

How Long Does Each Vyvgart Cycle Last?

Vyvgart is administered in cycles where you receive one infusion dose per week for four weeks. How long Vyvgart lasts is different for each person, but researchers for the European Medicines Agency found that patients in one study experienced the following results:

  • 11% felt benefits for five weeks
  • 32% for six to seven weeks
  • 23% for eight to 11 weeks
  • 34% for 12 weeks or more

When your symptoms return, your doctor may order another Vyvgart treatment cycle. Argenx reported that the average wait time from the initial infusion of the first treatment cycle was between 72 and 94 days, depending on how well patients responded to the medication.

How Soon Before Vyvgart Starts Working?

Vyvgart can start working quickly for some people. Most patients receiving Vyvgart infusions in the Argenx study started feeling better during their first four-week treatment cycle.

Some people reported improved muscle strength as early as one to two weeks after starting Vyvgart. Others may take a little longer. How fast it works can depend on your symptoms and how your body responds. You might notice:

  • Less muscle weakness
  • Better ability to speak, chew, or swallow
  • Less drooping in your eyelids
  • Improved breathing or less fatigue

Relief tends to build during the treatment cycle. Your doctor will check your progress to decide when you need another round.

After your doctor prescribes a Vyvgart cycle, you will usually receive the treatments in a medical setting like an outpatient infusion center. Each infusion lasts about one hour, followed by an additional hour of monitoring for potential reactions. There are a few steps you can take to make the infusion process go more smoothly, if not more quickly:

  1. Drink plenty of water and eat as you normally would
  2. Get a full night’s sleep before your infusion
  3. Wear loose, comfortable clothes
  4. Arrive at least 15 minutes early for your appointment

It’s also important to discuss any changes in how you’re feeling with the infusion specialist while you’re receiving the dose so that they can identify and manage potential adverse reactions.

Tell Your Doctor How Long Vyvgart Lasts

Every gMG patient is different. Monitoring your symptoms and communicating how long Vyvgart lasts in your case is essential so you and your doctor can plan additional treatment cycles to manage your condition.
