argenx announces efficacy and expanded safety data from Phase 1 trial of ARGX-111
- Additional preclinical data support potential of ARGX-111 in targeting tumor microenvironment
Breda, the Netherlands/Ghent, Belgium –argenx (Euronext Brussels: ARGX), a clinical-stage biopharmaceutical company focused on creating and developing differentiated therapeutic antibodies to treat cancer and severe autoimmune diseases, today announced data published in conjunction with the American Society of Clinical Oncology (ASCO) 2016 Annual Meeting (Chicago, USA) presenting efficacy and safety data from its ARGX-111 Phase 1 expansion study in patients with MET amplified tumors. The data confirm ARGX-111 to have a favorable safety profile and to continue to show signs of anti-tumor activity. The abstract can be accessedhere.
In addition, data from preclinical studies demonstrate depletion of MET-positive myeloid-derived suppressor cells (MDSCs) by ARGX-111. These data provide an exciting new perspective for therapeutic intervention in MET cancer biology in targeting both the tumor cells and the tumor microenvironment.
About ARGX-111
ARGX-111 is a Met-targeting human monoclonal SIMPLE Antibody™ that modulates all known mechanisms of action of the receptor. ARGX-111 benefits from POTELLIGENT®-enhanced Antibody Dependent Cellular Cytotoxicity (ADCC), which drives the immune system to destroy
c-MET positive cells of the primary tumor and the circulating tumor cells that are responsible for metastasis; and from NHance®, which is thought to drive tissue penetration. This unique combination results in a potentially best-in-class drug candidate for c-Met therapies. ARGX-111 is tested in a Phase 1 safety expansion cohort in MET-amplified patients.
