On June 14, 2017 rgenx (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 presented updated data from its Phase 1b expansion study of ARGX-110 in patients with different subtypes of relapsed/refractory cutaneous T-cell lymphoma (CTCL) and various disease stages, at the International Conference of Malignant Lymphoma (ICML) in Lugano, Italy (Filing, 6-K, argenx, JUN 14, 2017, View Source [SID1234519530]).

“Analysis of the skin biopsies continues to strengthen the biological rationale of targeting CD70 with ARGX-110. Clinical activity was observed in patients across different CTCL subtypes (mycosis fungoides, Sézary syndrome, panniculitis-like TCL) and different disease stages whilst the drug shows a favorable safety and tolerability profile,” commented Nicolas Leupin, Chief Medical Officer of argenx. “Improved pruritis was observed in some of the patients and will be further monitored to explore ARGX-110 modes of action in skin of CTCL patients.”
The updated data from the currently ongoing Phase Ib study continue to show evidence of clinical and/or biological anti-tumor activity with ARGX-110. We observed partial response and stable disease, respectively, in three and seven out of 16 patients with highly relapsed/refractory CTCL and confirmed overexpression of CD70. Treatment-emerging adverse events were reported for six out of 16 patients. The poster presented at ICML can be accessed from the “Downloads” section of the argenx website.
In April 2017, argenx announced the initiation of a Phase II trial of ARGX-110 as a monotherapy in relapsed/refractory CTCL patients, in order to further examine the activity of the product candidate, using the optimal dose and biomarker panel determined during the Phase Ib trial.
About ARGX-110
ARGX-110 is a SIMPLE Antibody targeting CD70, an immune checkpoint target involved in hematological malignancies, several solid tumors and severe autoimmune diseases. ARGX-110 is designed to: i) block CD70, ii) kill cancer cells expressing CD70 through antibody-dependent cellular phagocytosis and iii) restore immune surveillance against solid tumors (Silence K. et al. mAbs 2014; 6 (2):523-532). ARGX-110 is currently being evaluated in patients with hematological and solid tumors. ARGX-110 is currently being evaluated in a Phase II trial in combination with azacitidine in patients with newly diagnosed acute myeloid leukemia (AML) and high-risk myelodysplastic syndrome (MDS) and a Phase II trial in patients with relapsed/refractory CTCL. Preclinical work on ARGX-110 in AML was performed in collaboration with the Tumor Immunology Lab of Prof. A. F. Ochsenbein at the University of Bern, who won, together with Prof. Manz from the University Hospital of Zürich, the prestigious 2016 Otto Naegeli Prize for his breakthrough research on CD70/CD27 signaling with therapeutic potential for cancer patients.
