Rozanolixizumab is under clinical development with the aim of improving the lives of people with pathogenic IgG-autoantibody-driven autoimmune diseases, including ITP, myasthenia gravis (MG) and chronic inflammatory demyelinating polyneuropathy (CIDP), by driving removal of pathogenic IgG autoantibodies.
Rozanolixizumab, an investigational monoclonal antibody, was granted orphan drug designation for the treatment of ITP by the US Food and Drug Administration on 30 April 2018 and by the European Commission on 11 January 2019.(12,13) The safety and efficacy of rozanolixizumab has not been established; it is not currently approved by any regulatory authority worldwide.
About UCB in Rare Diseases
At UCB, we don't just see patients or population sizes, we see people in need. Through decades of serving the neurology and immunology communities, we have improved lives with impactful medicines and by enhancing the social and emotional well-being of patients. As a continuation of our heritage, we are now expanding our efforts to tackle rare neurological and immunologic diseases where current options offer little hope, including investigational treatments for primary immune thrombocytopenia (ITP), myasthenia gravis (MG), chronic inflammatory demyelinating polyneuropathy (CIDP) and progressive supranuclear palsy (PSP).
UCB, Brussels, Belgium (www.ucb.com) is a global biopharmaceutical company focused on the discovery and development of innovative medicines and solutions to transform the lives of people living with severe diseases of the immune system or of the central nervous system.
