2017 was a year of tremendous momentum for argenx as we made progress on our pipeline and increased value for our shareholders. As a result of this focused execution, we believe we are well-positioned to advance our pipeline through several key clinical milestones in the year ahead, commented Tim Van Hauwermeiren, CEO of argenx. In December, we announced positive clinical data from our Phase 2 trial of ARGX-113 for the treatment of generalized myasthenia gravis and plan to advance ARGX-113 to Phase 3 in this indication. This also marked the first dataset from our Phase 2 program aimed at evaluating the role of ARGX-113 in indications where the reduction of pathogenic autoantibodies may mediate disease. We continue to evaluate the asset in two additional Phase 2 indications, immune thrombocytopenia and pemphigus vulgaris, and expect to report data from both in the second half of 2018. We also advanced our lead oncology asset and reported interim data from our Phase 1/2 trial of ARGX-110 in acute myeloid leukemia, which we expect to transition into a Phase 2 trial this year. We feel that our achievements in 2017 have further validated our disciplined and differentiated approach to antibody development and look forward to providing updates on several important catalysts from our wholly-owned pipeline and strategic collaborations in 2018."
