argenx SE, a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, announced that the U.S. Food and Drug Administration (FDA) approved a new option for patients to self-inject VYVGART® Hytrulo with a prefilled syringe (efgartigimod alfa and hyaluronidase-qvfc) for the treatment of adult patients with generalized myasthenia gravis (gMG) who are anti-acetylcholine receptor (AChR) antibody positive and adult patients with chronic inflammatory demyelinating polyneuropathy (CIDP).

“Today’s FDA approval provides a new self-injection option across both approved indications in the U.S. that is designed for patients who seek more independence with their treatment,” said Luc Truyen M.D., Ph.D., Chief Medical Officer, argenx. “We understand patients experience MG and CIDP in different ways, and our prefilled syringe is an important innovation that provides patients with more freedom and flexibility to self-administer VYVGART Hytrulo. Whether patients prefer to receive their treatment in a physician’s office, at home, or while traveling, they can experience treatment on their own terms and continue to benefit from VYVGART Hytrulo’s favorable safety profile and strong efficacy.”

VYVGART Hytrulo prefilled syringe for self-injection is approved as a 20-to-30-second subcutaneous injection administered by a patient, caregiver, or healthcare professional. Patients are able to self-inject after proper instruction in subcutaneous injection technique. The single dose prefilled subcutaneous injection was developed as part of argenx’s exclusive partnership with Halozyme’s ENHANZE® drug delivery technology, which enables rapid, high-volume delivery of biologics.

“I am excited to offer my patients living with gMG and CIDP the option of the new prefilled syringe for VYVGART Hytrulo,” said Dr. Beth Stein, M.D., Director of Neuromuscular Diseases, St. Joseph’s Health, Clifton, NJ. “This new self-injection option will lead to more convenient and flexible administration for patients, empowering them to decide when and where they receive treatment. A ready-to-use option enhances patient independence and reduces the time required for treatment, making disease management and control more seamless.”

The approval of VYVGART Hytrulo prefilled syringe for self-injection is supported by data from studies evaluating its bioequivalence to VYVGART Hytrulo in a vial. In addition, human factors validation studies demonstrated that participants with gMG or CIDP, or their caregivers, safely and successfully prepared and administered VYVGART Hytrulo with the prefilled syringe. Previous FDA approval of VYVGART Hytrulo for patients with gMG and CIDP was based on the global Phase 3 ADAPT, ADAPT-SC and ADHERE trials.

“argenx is a trusted partner in the MG patient community, continuously innovating to meet the evolving needs of patients. This new self-injection option is a natural progression, empowering individuals to take control of their treatment and working toward achieving a greater sense of normalcy in their lives,” said Samantha Masterson, President and CEO of the Myasthenia Gravis Foundation of America.
        
“The daily burden of CIDP from both the symptoms of the disease and interruption to daily life creates profound unseen challenges for patients,” said Lisa Butler, Executive Director, GBS-CIDP Foundation. “Effective new treatments that reduce the need for frequent clinic visits are a welcome option for active patients seeking to regain time and a sense of normalcy in their daily routine. Today’s news about the approval of argenx’s prefilled syringe for at-home self-injection is a significant step forward for those patients seeking a new treatment option.”
