argenx Highlights Data Showing Patient Impact Across Multiple Immunology Programs at 2024 American Association of Neuromuscular & Electrodiagnostic Medicine Annual Meeting and Myasthenia Gravis Foundation of America Scientific Sessions

Long-term and real-world data of VYVGART® (efgartigimod alfa-fcab) and VYVGART® Hytrulo (efgartigimod alfa and hyaluronidase-qvfc) demonstrate speed of onset, depth of response, and durability of response

VYVGART demonstrates consistent, favorable safety profile from follow-up safety data that totals >8,000 patient years; no vaccinations required and no impact on human serum albumin levels

Real-world data show more than 50 percent of gMG patients demonstrate substantial and sustained reduction in steroid use following VYVGART initiation

argenx continues to expand its reach in neurology through pipeline programs, including empasiprubart advancing in MMN and ARGX-119 in ALS and CMS

October 15, 2024 – 7:00am CET

Amsterdam, the Netherlands – argenx SE (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced the presentation of clinical and real-world data across its growing immunology pipeline at the 2024 American Association of Neuromuscular & Electrodiagnostic Medicine (AANEM) Annual Meeting and Myasthenia Gravis Foundation of America (MGFA) Scientific Sessions in Savannah, GA from October 15-18, 2024.

“VYVGART continues to deliver impactful benefits to patients in terms of safety, speed of onset, depth of response, and durability of response,” said Luc Truyen, M.D., Ph.D., Chief Medical Officer, argenx. “The robust data we are showing at AANEM and MGFA continue to confirm VYVGART as the leading innovative biologic with an established ability to reduce steroid usage, drive minimal symptom expression for gMG patients, and reduce CIDP symptoms quickly. In addition to VYVGART, we are excited to highlight our growing neurology pipeline, including empasiprubart and ARGX-119, through which we can advance our mission of delivering transformative outcomes for even more patients.”

VYVGART and VYVGART Hytrulo Demonstrate Rapid, Deep and Sustained Responses in gMG and CIDP

The data presented at AANEM continue to demonstrate the significant impact of VYVGART (including VYVGART Hytrulo), the first-in-class neonatal Fc receptor (FcRn) blocker for people living with generalized myasthenia gravis (gMG) and chronic inflammatory demyelinating polyneuropathy (CIDP). VYVGART is setting a new treatment standard in gMG and has shown rapid, deep and sustained responses, enabling a majority of patients to achieve minimal symptom expression (MSE) with a consistent and favorable safety profile and more than 8,000 patient years of safety data. Based on real- world data, more than half of patients can reduce steroid use by >5mg/day following VYVGART initiation. In CIDP, a majority of patients in the ADHERE trial responded to VYVGART Hytrulo and experienced reduced risk of relapse versus placebo and improvements in motor function and muscle strength, regardless of prior CIDP treatment.

Highlights from VYVGART data presented at AANEM and MGFA:

	·	Early Line Use and Meaningful Steroid Reduction: VYVGART demonstrates consistent improvement across gMG patient subtypes, including those on mestinon alone, indicating its efficacy in early line use. Real-world gMG data show that at one-year post VYVGART initiation, 55% of patients reduced corticosteroid use by ≥5 mg/day and 42% of patients had achieved steroid doses of ≤5mg/day.
	·	Expansion to Seronegative and Ocular MG: argenx is honoring its long-term commitment to the broader MG community with two Phase 3 studies ongoing in additional MG patient populations, including seronegative (ADAPT-SERON) and ocular MG (ADAPT-OCULUS). Seronegative (AChR-) gMG patients evaluated in VYVGART clinical studies experienced consistent and clinically meaningful MG-ADL improvements, including patients achieving MSE.
	·	Sustained Functional Benefit in CIDP: VYVGART Hytrulo showed sustained functional benefit in motor function and muscle strength, regardless of prior treatment, which was maintained through ADHERE and the open-label extension study (through week 24).
	·	Consistent, Favorable Safety Profile: VYVGART’s consistent and favorable safety profile has been established across multiple autoimmune diseases with no increase in the incidence of adverse events with increased exposure. The unique safety profile of VYVGART is further supported by no black box warnings, no labs or immunoglobulin (Ig) monitoring, and no vaccination requirements.

Advancing Immunology Pipeline Across Two First-in-Class Opportunities to Reach New Patients

argenx will also highlight two additional pipeline candidates, including Phase 2 ARDA data of empasiprubart (anti-C2 inhibitor) for the treatment of multifocal motor neuropathy (MMN), and clinical trial designs of ARGX-119 (muscle-specific kinase (MuSK) agonist) for the treatment of congenital myasthenic syndromes (CMS) and amyotrophic lateral sclerosis (ALS).

Cohort 1 data from the Phase 2 ARDA study will be presented in a poster, showing treatment with empasiprubart for MMN reduced the risk of IVIg retreatment by 91% (HR: 0.09 [95% CI: 0.02–0.44]) and demonstrated significant improvement in grip strength in both hands as compared to placebo. Data from a Patient Global Impression of Change scale show 94.4% of patients said they improved on empasiprubart from the start of the study, compared to 11.1% of placebo patients. As part of its commitment to the MMN community, argenx initiated the iMMersioN longitudinal study of ~150 patients to collect data on the impact of disease and burden of current treatment options on clinical outcomes and quality of life measures. A Phase 3 study of empasiprubart in MMN will start by the end of 2024.

About VYVGART

VYVGART is a human IgG1 antibody fragment that binds to the neonatal Fc receptor (FcRn), resulting in the reduction of circulating IgG autoantibodies. It is the first approved FcRn blocker in the United States, EU, China and Canada for the treatment of adults with generalized myasthenia gravis (gMG) who are anti- acetylcholine receptor (AChR) antibody positive and in Japan for the treatment of adults with gMG who do not have sufficient response to steroids or non-steroidal immunosuppressive therapies (ISTs).

About VYVGART^®Hytrulo

VYVGART Hytrulo is a subcutaneous combination of efgartigimod alfa, a human IgG1 antibody fragment marketed for intravenous use as VYVGART^®, and recombinant human hyaluronidase PH20 (rHuPH20), Halozyme’s ENHANZE^® drug delivery technology to facilitate subcutaneous injection delivery of biologics. In binding to the neonatal Fc receptor (FcRn), VYVGART Hytrulo results in the reduction of circulating IgG. It is the first-and-only approved FcRn blocker administered by subcutaneous injection.

VYVGART Hytrulo is the proprietary name in the U.S. for subcutaneous efgartigimod alfa and recombinant human hyaluronidase PH20. It may be marketed under different proprietary names following approval in other regions.

About Generalized Myasthenia Gravis (gMG)

Generalized myasthenia gravis (gMG) is a rare and chronic autoimmune disease where IgG autoantibodies disrupt communication between nerves and muscles, causing debilitating and potentially life-threatening muscle weakness. Approximately 85% of people with MG progress to gMG within 24 months,1 where muscles throughout the body may be affected. Patients with confirmed AChR antibodies account for approximately 85% of the total gMG population.

About Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)

Chronic inflammatory demyelinating polyneuropathy (CIDP) is a rare and serious autoimmune disease of the peripheral nervous system. Although confirmation of disease pathophysiology is still emerging, there is increasing evidence that IgG antibodies play a key role in the damage to the peripheral nerves. People with CIDP experience fatigue, muscle weakness and a loss of feeling in their arms and legs that can get worse over time or may come and go. These symptoms can significantly impair a person's ability to function in their daily lives. Without treatment, one-third of people living with CIDP will need a wheelchair.

About Empasiprubart

Empasiprubart (ARGX-117) is a first-in-class humanized monoclonal antibody that binds C2 and blocks activation of both the classical and lectin pathways of the complement cascade, leaving the alternative pathway intact for its antimicrobial properties. By blocking complement activity upstream of C3 and C5, empasiprubart has the potential to reduce tissue inflammation and cellular damage, representing a broad pipeline opportunity across multiple severe autoimmune indications. In addition to multifocal motor neuropathy, argenx is evaluating empasiprubart in delayed graft function following kidney transplant, dermatomyositis and chronic inflammatory demyelinating polyneuropathy.

About Multifocal Motor Neuropathy

Multifocal motor neuropathy (MMN) is a rare, severe, chronic autoimmune disease of the peripheral nervous system. The disease is characterized by slowly progressive, asymmetric muscle weakness mainly of the hands, forearms and lower legs. MMN is often associated with the presence of anti-GM1 IgM autoantibodies, leading to activation of the classical complement pathway, driving subsequent axon damage. High-dose IVIg is the only approved treatment for MMN and patients typically experience disease progression despite therapy, indicating an unmet need for efficacious and better tolerated therapeutic options.

About ARGX-119

ARGX-119 is a humanized agonistic monoclonal antibody (mAb) that targets and activates muscle- specific kinase (MuSK) to promote maturation and stabilization of the neuromuscular junction (NMJ). MuSK is a receptor kinase that has a critical role in the structure and function of the NMJ. ARGX-119 is being developed as a potential therapy for patients with neuromuscular disease.

About Congenital Myasthenic Syndromes (CMS)

Congenital Myasthenic Syndromes (CMS) are a heterogenous group of rare genetic disorders of the neuromuscular junction (NMJ) that lead to muscle weakness. CMS cases are classified into subtypes depending on the underlying genetic mutation. While clinical features vary widely across and within subtypes, the predominant manifestation of CMS is fatigable weakness. Age of onset varies widely; while many patients are diagnosed in infancy or early childhood, patients with milder phenotypes may not present or be diagnosed until adulthood.

About Amyotrophic Lateral Sclerosis (ALS)

ALS is a neurodegenerative disorder of the brain and spinal cord leading to deteriorating muscle function, weakness and atrophy. The multisystemic nature can have impacts throughout the body with specific signs and symptoms associated with lower motor neuron and upper motor neuron loss. Life expectancy is typically 2.5-5 years from diagnosis.
