argenx announces collaboration with Broteio Pharma to develop therapeutic antibody

argenx, 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 entered into a new collaboration with Broteio Pharma B.V. to develop an antibody against a novel target in the complement cascade with therapeutic potential in autoantibody- and complement-mediated indications including autoimmune haemolytic anaemia (AIHA) and antibody mediated rejection (AMR) following organ transplantation.

“This collaboration represents the latest success for our Innovative Access Program and aligns with our corporate mission to develop differentiated antibodies for cancer and severe autoimmune diseases. The novel antibody targets a component of the complement cascade with therapeutic potential in both orphan and large market indications like Ischemia/Reperfusion Injuries (IRI),” comments Tim Van Hauwermeiren, CEO of argenx. “This new therapeutic antibody has the potential to act alongside our lead product candidate ARGX-113 in a synergistic fashion. ARGX-113 targets FcRn in order to clear pathogenic IgG antibodies while our new complement-targeted antibody can also address IgM mediated autoimmune diseases. This transaction positions us to further build out the depth and breadth of our autoimmune disease pipeline.”

Under the terms of the agreement, argenx and Broteio will jointly develop the complement-targeted antibody to establish preclinical proof-of-concept using argenx’s proprietary suite of technologies. Upon successful completion of these studies, argenx may exercise an exclusive option to license the program and assume responsibility for further development and commercialization.
