Announcing four new efgartigimod indications to be initiated in 2022: membranous nephropathy, lupus nephritis, Sjogren’s syndrome, COVID-19 mediated postural orthostatic tachycardia syndrome (POTS)

Anticipate clinical development programs in 12 autoimmune conditions across four therapeutic franchises by end of 2022

BREDA, The Netherlands I January 07, 2022 I argenx (Euronext & Nasdaq: ARGX), a global immunology company committed to improving the lives of people suffering from severe autoimmune diseases, today announced its strategic priorities for 2022 and highlighted recent achievements from its broad immunology pipeline. Additionally, the Company provided financial guidance for 2022.

“We enter 2022 very excited about the year ahead, having achieved our first FDA approval and initiated our commercial launch of VYVGART in the United States. With these accomplishments, we are well on our way to realizing our goal to become a leading, multi-product immunology company and believe we have the right team, a differentiated pipeline, and a sustainable innovation engine to support our vision,” commented Tim Van Hauwermeiren, Chief Executive Officer of argenx.

“Beyond this launch, we are focused on expanding and accelerating the clinical development of our efgartigimod portfolio. Toward that end, we expect to report data from five registrational trials by the end of the first quarter of 2023 and to initiate trials in four new indications this year through partnership agreements with Zai Lab and IQVIA. We believe our leadership in neonatal Fc receptor (FcRn) blockade, along with our robust immunology pipeline, position 2022 to be a transformational year for argenx,” continued Mr. Van Hauwermeiren.

Strategic Priorities

  • Dermatology franchise
          ADDRESS: Topline data of SC efgartigimod for pemphigus foliaceous and vulgaris expected in fourth quarter of 2022

Efgartigimod development portfolio to expand to ten high-need autoimmune conditions by end of 2022, solidifying argenx’s leadership position in FcRn blockade

  • Trial designs finalized in fifth and sixth potential indications following regulatory consultation
    • BALLAD: Registrational trial initiated at end of 2021 of SC efgartigimod for bullous pemphigoid; interim analysis planned of first 30 patients
    • ALKIVIA: Registrational trial of SC efgartigimod for idiopathic inflammatory myopathy (myositis) to initiate in first quarter of 2022; interim analysis planned of first 30 patients of each subtype (immune-mediated necrotizing myopathy, anti-synthetase syndrome and dermatomyositis)
  • Through partnership agreement, Zai Lab to launch proof-of-concept trials in two new kidney conditions in 2022: lupus nephritis and membranous nephropathy
    • argenx to lead any global registrational program for each potential indication
  • argenx entered into strategic partnership with IQVIA to leverage its global clinical development capabilities and accelerate expansion of efgartigimod into additional potential indications
    • Proof-of-concept trials to initiate in two autoimmune conditions:
      • Primary Sjogren’s syndrome in second half of 2022
      • COVID-19-mediated postural orthostatic tachycardia syndrome (POTS) in mid-2022, which is increasingly reported in patients who continue to have long-lasting symptoms after complete recovery of COVID-19 infection

ARGX-117, a novel C2 inhibitor, has potential to be second pipeline-in-a-product for multiple autoimmune indications

  • Proof-of-concept trial initiated at end of 2021 in multifocal motor neuropathy
  • Second proof-of-concept trial to initiate in second half of 2022 for prevention of delayed graft function and/or allograft failure after kidney transplantation

Continued investment in Immunology Innovation Program to broaden autoimmune pipeline for sustained value creation opportunities

  • Phase 1 dose-escalation trial of ARGX-119, an agonist SIMPLE Antibody™ to the muscle-specific kinase receptor (MuSK), to start after Clinical Trial Application filing in fourth quarter of 2022
    • Trial will evaluate safety, tolerability, pharmacokinetics and pharmacodynamics in healthy volunteers, and also early signal detection in patients

Financial Guidance

As of December 31, 2021, argenx had approximately $2.3 billion in cash, cash equivalents and current financial assets. Based on current plans to fund anticipated operating expenses and capital expenditures, argenx expects to utilize approximately half of its available cash in 2022. The increased spend will support the global VYVGART launches, clinical development of efgartigimod and ARGX-117 in 12 total indications, investment in the global supply chain, and continued focus on pipeline expansion through the Immunology Innovation Program.
