We are pleased to share an important update from argenx regarding the treatment landscape for generalized myasthenia gravis (gMG).
The U.S. Food and Drug Administration (FDA) has approved a label expansion for VYVGART (efgartigimod alfa-fcab) and VYVGART Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) to include all adult patients living with gMG, regardless of antibody status. This means the therapies are now approved for patients who are anti-AChR antibody positive, anti-MuSK antibody positive, anti-LRP4 antibody positive, as well as those who are triple seronegative.
This approval is based on results from the Phase 3 ADAPT SERON study, which demonstrated rapid, statistically significant, and clinically meaningful improvements in daily functioning compared to placebo. Improvements were observed across symptoms impacting daily life, including speech, vision, swallowing, and physical function.
This milestone is particularly meaningful for individuals who do not have detectable AChR antibodies—a community that has historically faced limited inclusion in clinical research and fewer targeted treatment options.
We recognize the important role you play in supporting individuals living with MG and are committed to keeping you informed as new developments emerge.
Monica Seles Speaks Out About Living with Myasthenia Gravis and partners with argenx in the Go for Greater initiative
Posted by Giselle Murillo
Nine-time Grand Slam champion Monica Seles has revealed her diagnosis with myasthenia gravis (MG), which she has been living with since 2022.
She first noticed symptoms such as double vision and weakness in her arms and legs, which made everyday tasks difficult, and is now using her platform to educate and support others.
Partnering with argenx’s Go for Greater initiative, Seles hopes to raise awareness, connect patients with support resources, and inspire advocacy in the MG community. “I can raise awareness of this disease, empower patients to advocate for themselves, and help them connect with the MG community,” she says.
Argenx announces innovative pre-filled syringe self-injection option for adults with gMG
Posted by myasthenia
VYVGART Hytrulo prefilled syringe for self-injection (single-dose subcutaneous injection: 200 mg/mL of efgartigimod alfa and 2,000 U/mL of hyaluronidase) has been approved by the U.S. FDA for the treatment of adults with anti-AChR antibody-positive generalized myasthenia gravis (gMG). The VYVGART Hytrulo prefilled syringe is a self-injection that takes about 20-30 seconds.* It is injected under the skin (subcutaneously). Patients and/or their caregivers will receive in-person training at home or in their doctor’s office until they’re ready to inject on their own. They’ll also get a demonstration kit to help them practice.
argenx will provide support and educational resources to patients who are prescribed VYVGART Hytrulo through our My VYVGART Path Patient Support Program. Resources are available throughout the entire treatment journey and include: disease and product education, access to support and benefits verification, and financial assistance programs for eligible patients. If patients are self-injecting with the VYVGART Hytrulo prefilled syringe, a Nurse Case Manager can also provide additional educationalresources on self-injection.
On behalf of all of us at argenx, I personally want to thank you for your support. Your organization’s continued partnership has helped us bring this milestone to fruition for the gMG community. We are so honored to have you as an argenx advocacy partner.
