Management to host conference call today at 2:30 pm CEST (8:30 am ET)

“We’ve had a strong start to 2021 with the acceptance for review of the BLA and J-MAA for efgartigimod in gMG by the regulatory agencies in the U.S. and Japan. The submissions in China and the EU are on track and we are well-positioned for a global launch of our first-in-class FcRn antagonist. We are building an exceptional team with significant launch experience in neurology and rare disease and hope to reach patients this year,” said Tim Van Hauwermeiren, Chief Executive Officer of argenx.   

“Efgartigimod has the potential to help people living with gMG as well as several other severe autoimmune diseases mediated by IgG autoantibodies. Our team is advancing registrational trials across four indications with plans to start enrollment in two additional efgartigimod indications this year. We are also broadening our reach within autoimmunity with our first-in-class C2 inhibitor, ARGX-117, from which we will have Phase 1 data mid-year. To complement our clinical pipeline, we continue to invest in our discovery capabilities through our Immunology Innovation Program and strategic technology partnerships that position us well to generate long-term value for shareholders. We are closer each day to building an integrated, innovative, global immunology organization with the goal of impacting the lives of patients,” concluded Mr. Van Hauwermeiren.

FIRST QUARTER 2021 FINANCIAL RESULTS (CONSOLIDATED)

DETAILS OF THE FINANCIAL RESULTS 

As of January 1, 2021, the Company changed its functional and presentation currency from euro to U.S. dollars, which results in reporting its financial highlights in U.S. dollar as compared to euro in prior periods. Historical financials have been converted at the average exchange rate of the related period. 

Cash, cash equivalents and current financial assets totaled $2,907.4 million on March 31, 2021, compared to $1,996.5 million on December 31, 2020. The increase in cash, cash equivalents and current financial assets resulted primarily from (i) the closing of a global offering, which resulted in the receipt of $1,092.1 million in net proceeds in February 2021, (ii) the net receipt of a $73.1 million non-creditable, non-refundable development cost-sharing payment in the form of newly issued Zai Lab shares received as part of the strategic collaboration for efgartigimod in Greater China, partially offset by (iii) the payment of $98.0 million related to the purchase of a priority review voucher from Bayer HealthCare Pharmaceuticals and other net cash flows used in operating activities.

Total operating income increased by $141.6 million for the three months ended March 31, 2021 to $167.4 million, compared to $25.8 million for the three months ended March 31, 2020. The increase was primarily due to the closing of the strategic collaboration for efgartigimod with Zai Lab, resulting in the recognition of $151.9 million in collaboration revenue.

Research and development expenses increased by $17.7 million for the three months ended March 31, 2021 to $122.3 million, compared to $104.7 million for the three months ended March 31, 2020. The increase in the first three months of 2021 resulted primarily from higher external research and development expenses, mainly related to the efgartigimod program in multiple indications and other clinical and preclinical programs. Furthermore, the research and development personnel expenses increased due to a planned increase in headcount and the increased costs of the share-based payment compensation plans related to the grant of stock options.

Selling, general and administrative expenses totaled $56.3 million for the three months ended March 31, 2021, compared to $27.6 million for the three months ended March 31, 2020. The increase resulted primarily from higher personnel expenses, including the costs of the share-based payment compensation plans related to the grant of stock options, and consulting fees linked to the preparation of a possible future commercialization of efgartigimod.

The increase in fair value on non-current financial assets amounted to $11.2 million for the three months ended March 31, 2021, which is the result of the closing of a Series B financing round of AgomAb Therapeutics, 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.

Exchange losses totaled $28.8 million for the three months ended March 31, 2021, compared to an exchange gain of $23.0 million for the three months ended March 31, 2020. As a result of the change in the Company’s functional and presentation currency, the exchange losses for the three months ended March 31, 2021 are reflecting the unfavorable change in euro/U.S. dollar exchange rate, mainly attributable to unrealized exchange rate losses on cash, cash equivalents and current financial asset position in euro.

FINANCIAL GUIDANCE 

Based on current plans to fund anticipated operating expenses and capital expenditures, argenx continues to expect its 2021 cash burn to approximately double from 2020. The increased spend will support the Company’s transition to an integrated immunology company, including the build-out of global commercial infrastructure and drug product inventory ahead of the expected launch of efgartigimod in gMG in the U.S, the advancement of its clinical-stage pipeline, including seven expected global trials of efgartigimod, and the continued investment in its Immunology Innovation Program.
