  • Registrational ALKIVIA trial of SC efgartigimod on track to start in third quarter of 2022 for three subtypes of idiopathic inflammatory myopathies (myositis), including immune-mediated necrotizing myopathy, anti-synthetase syndrome and dermatomyositis; interim analysis planned of first 30 patients of each subtype

• Hematology franchise

  • Enrollment expanded in second registrational ADVANCE-SC trial of SC efgartigimod for primary immune thrombocytopenia (ITP) based on key learnings from positive ADVANCE-IV trial; topline data now expected in second half of 2023

Creation of OncoVerity
argenx, the University of Colorado Anschutz Medical Campus and UCHealth created an asset-centric spin-off, OncoVerity, Inc., focused on optimizing and advancing the development of cusatuzumab, a novel anti-CD70 antibody, in acute myeloid leukemia (AML). OncoVerity will be an entity of co-creation, combining the extensive translational biology insights from Dr. Clayton Smith, M.D. from the University of Colorado with the experience from argenx on the CD70/CD27 pathway. OncoVerity is the fourth spin-off company from argenx’s Immunology Innovation Program.

SECOND QUARTER 2022 FINANCIAL RESULTS

ARGENX SE
UNAUDITED CONDENSED CONSOLIDATED INTERIM STATEMENT OF PROFIT OR LOSS

DETAILS OF THE FINANCIAL RESULTS

Total operating income for the second quarter and year-to-date in 2022 was $85.2 million and $116.7 million, respectively, compared to $320.1 million and $498.6 million for the same periods in 2021, and consists of:

• Product net sales from the sales of VYVGART for the three months ended June 30, 2022 were $74.8 million compared to $21.2 million for three month ended March 31, 2022, following the approval of VYVGART by the U.S. Food and Drug Administration (FDA) on December 17, 2021 and Pharmaceuticals and Medical Devices Agency (PMDA) in Japan on January 20, 2022. No product net sales were recognized during the same period in 2021.

• Collaboration revenue for the second quarter and year-to-date in 2022 was $0.4 million and $2.6 million, respectively, compared to $312.2 million and $470.4 million for the same periods in 2021. The collaboration revenue for the three and six months ended June 30, 2021 was primarily attributable to the recognition of the transaction price as a consequence of the termination of the collaboration agreement with Janssen, resulting in the recognition of $311 million in collaboration revenue.

• Other operating income for the second quarter and year-to-date in 2022 was $10.0 million, and $18.1 million, respectively, compared to $7.8 million and $28.2 million for the same periods in 2021. During the three months ended June 30, 2022, the fair value of the argenx profit share in AgomAb Therapeutics NV increased by $4.3 million. The increase is a result of the extension of a Series B financing round by AgomAb for which the Company maintains a profit share in exchange for granting the license for the use of HGF-mimetic antibodies from the SIMPLE Antibody™ platform.
  
  

Total operating expenses for the second quarter and year-to-date in 2022 were $259.7 million and $513.9 million, respectively, compared to $224.9 million and $403.5 million for the same periods in 2021, and consists of:

• Cost of sales for the second quarter and year-to-date in 2022 was $5.0 million and $6.4 million, respectively. The cost of sales were recognized with respect to the sale of VYVGART during the first half of 2022. There were no cost of sales recognized in the comparable prior year periods.

• Research and development expenses for the second quarter and year-to-date in 2022 were $126.9 million and $278.9 million, respectively, compared to $151.6 million and $273.9 million for the same periods in 2021. The research and development expenses mainly relate to external research and development expenses and personnel expenses incurred in the clinical development of efgartigimod in various indications and the expansion of our other clinical and preclinical pipeline candidates.

• Selling, general and administrative expenses for the second quarter and year-to-date in 2022 were $127.8 million and $228.7 million, respectively, compared to $73.3 million and $129.6 million for the same periods in 2021. The selling, general and administrative expenses mainly relate to professional and marketing fees linked to the commercialization of VYVGART in the U.S. and Japan and personnel expenses.
  
  

Exchange losses for the second quarter and year-to-date in 2022 were $46.2 million and $53.4 million, respectively, compared to exchange gains of $10.4 million and exchange loss of $18.4 million for the same periods in 2021. Exchange losses are mainly attributable to unrealized exchange rate losses on our cash, cash equivalents and current financial assets position in Euro.

Income tax for the second quarter and year-to-date in 2022 was $8.2 million and $11.1 of tax income, respectively, compared to $1.7 million and $12.8 million of tax expense for the same periods in 2021. Tax income for the three months ended June 30, 2022 consists of $2.7 million of income tax expense and $10.9 million of deferred tax income, compared to $3.2 million of income tax expense and $1.5 million of deferred tax income for the same period in 2021.

Net loss for the second quarter and year-to-date in 2022 was $208.7 million and $435.9 million, respectively, compared to net profit of $103.6 million and $63.2 million for the same periods in 2021.

Cash, cash equivalents and current financial assets totaled $2,597.4 million as of June 30, 2022, compared to $2,336.7 million as of December 31, 2021. The increase in cash and cash equivalents and current financial assets resulted primarily from the closing of a global offering of shares, including a U.S. offering and a European private placement, which resulted in the receipt of $761.0 million in net proceeds in March 2022, partially offset by net cash flows used in operating activities.

FINANCIAL GUIDANCE
Based on current plans to fund anticipated operating expenses and capital expenditures, argenx continues to expect its 2022 cash burn to be up to $1 billion. This will support the global VYVGART launches, clinical development of efgartigimod in 10 indications and ARGX-117 in two indications, investment in the global supply chain, and continued focus on pipeline expansion through the Immunology Innovation Program.
