The past year was one of significant growth for argenx, and we have seen the momentum maintained into the first months of 2017. We continued to build our proprietary pipeline and advanced both our lead programs, ARGX-113 and ARGX-110, through key safety and early efficacy inflection points. Our early studies guided us on the attributes of each drug and enabled us to choose the indications we believe were best-suited for Phase 2 study. By the end of the first quarter, we plan to launch four proof-of-concept Phase 2 studies: MG and ITP for ARGX-113, and AML and TCL for ARGX-110, commented Tim Van Hauwermeiren, CEO of argenx. We were also busy outside the clinic with the start of our collaboration with AbbVie for our novel immuno-oncology product, ARGX-115, under which we received an upfront payment of $40 million and through the expansion of our shareholder base with blue-chip U.S. investors resulting in a €46 million investment over the course of 2016.


  • Dosed first patient with ARGX-113 in Phase 2 proof-of-concept study for treatment of myasthenia gravis (MG).
  • Hosted workshop in conjunction with American Society of Hematology (ASH) Annual Meeting and provided updates on clinical data from multiple ascending dose (MAD) Phase 1 study with ARGX-113 in healthy volunteers showing comparable pharmacodynamics (PD) and pharmacokinetic (PK) patterns between lower dose (10 mg/kg) and higher dose (25 mg/kg).
  • Initiated Phase 1/2 clinical trial in combination with standard of care, azacytidine, in newly diagnosed acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS) patients.
  • Published new preclinical data in Journal of Experimental Medicine on CD70/CD27 pathway that provide further biological rationale for ARGX-110 therapy for treatment of AML.
  • Presented further efficacy and safety data from ongoing Phase 1b study in relapsed/refractory T-cell lymphoma (TCL) patients at ASH workshop.
  • Announced that Staten Biotech exercised its exclusive option to license ARGX-116, an anti-ApoC3 SIMPLE AntibodyTM with therapeutic potential in dyslipidemia.
  • Announced the extension of our strategic partnership with Shire for a further year until May 30, 2018.
