argenx reaches 50% enrollment in Phase 2 clinical trial of ARGX-113 in immune thrombocytopenia

 

argenx (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 announced that it has recruited 50% of the immune thrombocytopenia (ITP) patients in the Phase 2 proof-of-concept study of ARGX-113.

"We are pleased to have reached the 50% recruitment milestone in this study, which is enrolling on schedule," commented Nicolas Leupin, Chief Medical Officer of argenx. "We remain on track, and look forward to presenting top-line data from the ARGX-113 clinical trial in ITP in the second half of 2018, which will be our second indication with Phase 2 top-line data from ARGX-113."



The double-blind, placebo controlled Phase II study will enroll up to 36 ITP patients with platelet levels lower than 30 million per milliliter. ARGX-113 will be dosed on top of current standard of care, including corticosteroids and/or immunomodulatory agents and/or TPO-R agonists. The primary endpoints of the trial are safety and tolerability, and secondary endpoints are effect on platelet count and use of rescue treatment, and an assessment of pharmacokinetics (PK) and pharmacodynamic (PD) markers.



The ITP clinical trial was initiated in March 2017. ARGX-113 is also being studied in a Phase 2 proof-of-concept study for the treatment of myasthenia gravis (MG), which was initiated in January 2017.

Note

About ARGX-113
ARGX-113 is an investigational therapy for treatment of IgG-mediated autoimmune diseases. ARGX-113 is the Fc-portion of an antibody that has been modified by the argenx proprietary ABDEG(TM) technology to increase its affinity for FcRn beyond that of normal IgG antibodies. As a result, ARGX-113 blocks antibody recycling and leads to fast depletion of the autoimmune disease-causing IgG autoantibodies. The development work on ARGX-113 is done in close collaboration with Prof. E. Sally Ward (University of Texas Southwestern Medical and Texas A&M University Health Science Center, a part of Texas A&M University (TAMHSC)).



About argenx
argenx is a clinical-stage biotechnology company developing a deep pipeline of differentiated antibody-based therapies for the treatment of severe autoimmune diseases and cancer. We are focused on developing product candidates with the potential to be either first-in-class against novel targets or best-in-class against known, but complex, targets in order to treat diseases with a significant unmet medical need. Our ability to execute on this focus is enabled by our suite of differentiated technologies. Our SIMPLE Antibody(TM) Platform, based on the powerful llama immune system, allows us to exploit novel and complex targets, and our three antibody engineering technologies are designed to enable us to expand the therapeutic index of our product candidates.
