August 1, 2019

Breda, the Netherlands / Ghent, Belgium
– argenx (Euronext & Nasdaq: ARGX), a clinical-stage biotechnology company developing a deep pipeline of differentiated antibody-based therapies for the treatment of severe autoimmune diseases and cancer, today announced its financial results for the first half of 2019 and provided its second quarter business update and the outlook for the remainder of the year.

"We continue to execute on accelerating and expanding our robust, late-stage innovative clinical development programs, as we invest in forward integration across our organization to maximize value. Efgartigimod is the most advanced and also the broadest FcRn antagonist program with four indications and both intravenous and subcutaneous formulations. Enrollment for the Phase 3 ADAPT trial in generalized myasthenia gravis is progressing as planned, and we are on track to initiate before the end of the year the first of two pivotal Phase 3 trials, ADVANCE, for our global primary immune thrombocytopenia program, as well as a Phase 2 trial in chronic inflammatory demyelinating polyneuropathy. Our Phase 2 trial of efgartigimod in pemphigus vulgaris remains a priority, and we expect to report topline data in the first half of 2020," commented Tim Van Hauwermeiren, CEO of argenx. "As we move towards becoming a fully-integrated biotechnology company, we continue to invest in commercial infrastructure with the build-out of our neuromuscular and hematology franchises and the expansion of our global supply chain through our longstanding collaboration with Lonza, which is expected to support the commercial launch of efgartigimod in generalized myasthenia gravis in 2021."

During its 2019 R&D Day in May, argenx announced its plan to become a fully integrated, global immunology company in accordance with its “argenx 2021” vision, which includes building two successful commercial franchises in neuromuscular and hematological disorders.

Efgartigimod (ARGX-113): Potential to be best-in-class with broad applicability
Efgartigimod is a human IgG1 Fc fragment engineered to increase affinity for FcRn versus endogenous IgG, whilst preserving characteristic pH-dependent binding, which may contribute to efgartigimod’s relatively long serum half-life and pharmacodynamic effect, and may promote tissue penetration. Treatment with efgartigimod results in a targeted reduction of IgG autoantibodies and is a rational approach to diseases where IgGs are directly pathogenic. argenx is evaluating efgartigimod as a potential treatment for four high-value indications, including:

  • Generalized Myasthenia Gravis (gMG)
    • Global, multi-center Phase 3 ADAPT clinical trial, including ADAPT+ one-year open-label extension study, currently ongoing
    • With current enrollment on track, topline data are expected in second half of 2020
    • Results from completed Phase 2 clinical trial were published in Neurology
  • Primary Immune Thrombocytopenia (ITP)
    • Global Phase 3 program to include two registration trials that will be run concurrently
      • First trial (ADVANCE) to evaluate 10 mg/kg intravenous (IV) efgartigimod on top of standard of care medication, with enrollment up to 158 patients; primary endpoint includes achieving sustained platelet count response of at least 50×109/L
      • Second trial to evaluate 10 mg/kg IV induction period followed by subcutaneous (SC) injections, all on top of standard of care medication, to evaluate potential of SC product to maintain clinical benefit
      • Phase 3 program was developed following consultation with key regulatory agencies
    • ADVANCE Phase 3 clinical trial expected to start in second half of 2019
  • Pemphigus Vulgaris (PV)
    • Phase 2 proof-of-concept clinical trial ongoing and currently enrolling patients in third cohort with extended dosing of efgartigimod
    • Data from Phase 2 clinical trial expected in first half of 2020
  • Chronic Inflammatory Demyelinating Polyneuropathy (CIDP)
    • Phase 2 clinical trial on track to start in second half of 2019
    • Key opinion leader (KOL) event planned for fourth quarter 2019 to discuss Phase 2 trial design and unmet needs in CIDP

argenx entered into a global collaboration with Halozyme in February 2019 to develop a SC formulation of efgartigimod using Halozyme’s proprietary ENHANZE® drug delivery technology, gaining exclusive rights to the technology for the FcRn target.

  • First subject dosed in Phase 1 healthy volunteer (HV) trial evaluating safety, pharmacokinetics, pharmacodynamics and bioavailability of ENHANZE® SC formulation of efgartigimod
  • Initiation of study triggered $5 million milestone payment to Halozyme
  • Data from Phase 1 HV trial are expected by end of 2019 after which argenx will disclose a path forward in patients for ENHANZE® SC formulation of efgartigimod

Cusatuzumab (ARGX-110): First-in-class opportunity in acute myeloid leukemia (AML)
Cusatuzumab is a first-in-class monoclonal antibody inhibiting CD70, a target that is uniquely present on both leukemic stem cells and AML blasts but not healthy cells. It is being developed under an exclusive global collaboration and license agreement with Janssen for the treatment of AML, high-risk myelodysplastic syndromes and other hematological malignancies.

  • Phase 2 and registration-directed clinical trial in AML on track to start in second half of 2019
    • Trial to enroll up to 150 patients with previously untreated AML and who are not eligible for intensive chemotherapy
    • In this two-part trial, patients will first be randomized to receive one of two dose levels of cusatuzumab (10 mg/kg and 20 mg/kg) in combination with azacytidine (75 mg/m2) followed by an expansion cohort to evaluate efficacy of the selected dose of cusatuzumab

Early Development Programs

argenx announced during its R&D Day the expansion of its product pipeline with the addition of two new proprietary therapeutic candidates, ARGX-117 and ARGX-118. Both emerged from argenx’s Innovative Access Program, in which it collaborates closely with disease biology experts, bringing the argenx cutting-edge antibody discovery and engineering technologies to the heart of novel target research.

  • ARGX-117 is a complement-targeting antibody against C2, a component of both the classical and lectin pathways in the complement cascade
    • Potential therapeutic applications in multiple autoimmune diseases
    • argenx exercised its second exclusive license to Halozyme’s ENHANZE® technology for use with this molecule
    • Expected to file Clinical Trial Application (CTA) by end of 2019 with first-in-human trial expected to start in first quarter of 2020
  • ARGX-118 is a highly differentiated antibody against Galectin-10, the protein of Charcot-Leyden crystals (CLCs), which play a major role in severe asthma and the persistence of mucus plugs
    • Immunology breakthrough in airway inflammation
    • SIMPLE Antibody™ observed to have unique crystal-dissolving properties
    • Currently in final stages of lead optimization work
    • Data were published in Science by argenx collaborator Dr. Bart Lambrecht from VIB Inflammation Research Center supporting role of CLCs and potential of ARGX-118 in airway inflammation

Cash, cash equivalents and current financial assets at the end of the period
   944,283   338,852   

On June 30, 2019, cash, cash equivalents and current financial assets totaled €944.3 million, compared to €564.6 million on December 31, 2018. The increase in cash, cash equivalents and current financial assets resulted primarily from the closing of the exclusive global collaboration and license agreement for cusatuzumab with Janssen which resulted in a $300 million upfront payment and a $200 million equity investment in January 2019.

Total operating income increased by €30.8 million for the six months ended June 30, 2019 to reach €51.3 million, compared to €20.5 million for the six months ended June 30, 2018. The increase is primarily related to (i) a €16.0 million increase in the recognition of milestone payments following the initiation of a first-in-human clinical trial with ABBV-151 (formerly named ARGX-115) under the AbbVie collaboration, which triggered a $30 million milestone payment, (ii) an increase of €7.8 million related to the recognition of research and development service fees under the Janssen collaboration and (iii) an increase of €5.2 million, mainly driven by higher payroll tax rebates for employing certain research and development personnel.

Research and development expenses totaled €78.3 million and €34.4 million for the six months ended June 30, 2019 and 2018, respectively. The increase in the first six months of 2019 resulted primarily from higher external research and development expenses and personnel expenses, reflecting higher clinical trials costs and manufacturing expenses related to the development of argenx’s product candidate portfolio and the recruitment of additional employees to support research and development activities.

Selling, general and administrative expenses totaled €27.5 million and €11.5 million for the six months ended June 30, 2019 and 2018, respectively. The increase of €16.0 million in selling, general and administrative expenses for the six months ended June 30, 2019 primarily resulted from higher personnel expenses and consulting fees related to the preparation of a possible future commercialization of argenx’s lead product candidate efgartigimod.

For the six months ended June 30, 2019, financial income amounted to €7.2 million, compared to €1.3 million for the six months ended June 30, 2018. The increase of €5.9 million in the first six months of 2019 related primarily to an increase in the interest received on cash, cash equivalents and current financial assets.
Exchange gains totaled €2.5 million for the six months ended June 30, 2019, compared to the €4.0 million for the six months ended June 30, 2018 and were mainly attributable to unrealized exchange rate gains on argenx’s cash and current financial assets position in U.S. Dollars due to the favorable fluctuation of the EUR/USD exchange rate in the first six months of 2019.

The total comprehensive loss for the six months ended June 30, 2019 was €45.1 million, compared to €20.1 million for the six months ended June 30, 2018.

The 90 day average number of shares outstanding per June 30, 2019 was 38,026,040.

Financial Outlook
Based on the current objectives of the Company’s business plan, argenx expects that its existing cash, cash equivalents and investments will fund planned operating and capital expense requirements into 2021. With the launch of a second global Phase 3 trial for efgartigimod, the execution of the development plan for cusatuzumab, the build-out of the commercial organization, and the expansion of the Company’s ambition level within its growing business plan, argenx expects operating and capital expense requirements to continue to increase year-over-year.
