argenx reports third quarter 2017 financial results and

Breda, the Netherlands / Ghent, Belgium argenx (Euronext Brussels & 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 financial results and provided a business update for the third quarter ended September 30, 2017.

We made strong progress during the third quarter launching the Phase 2 study of ARGX-113 in pemphigus vulgaris (PV) and delivering on our promise to expand the ARGX-113 program into new, carefully selected indications. With data readouts expected in 2018 from the Phase 2 studies in myasthenia gravis (MG), immune thrombocytopenia (ITP) and now PV, we will evaluate ARGX-113 in indications where disease progression is driven by pathogenic autoantibodies of the Immunoglobulin G (IgG) type, commented Tim Van Hauwermeiren, CEO of argenx. We are also progressing well with our lead oncology candidate, ARGX-110, and expect interim data from both our Phase 1/2 trial in acute myeloid leukemia (AML) and Phase 2 trial in cutaneous T-cell lymphoma (CTCL) by the 2017 American Society of Hematology (ASH) Annual Meeting (December, 2017). Between our wholly-owned pipeline and our programs partnered with AbbVie, Leo Pharma and through our Innovative Access Program, we believe we are very well-positioned for a catalyst-rich 2018.

  • Completed enrollment for Phase 2 clinical trial of MG.

  • Announced orphan drug designation by U.S. Food and Drug Administration for ARGX-113 for the treatment of MG.
