Another candidate, ANX009, is currently in Phase Ib studies for lupus nephritis. Additionally, ANX007 is progressing through Phase II clinical trials for the treatment of geographic atrophy, an eye disease. Further investigational assets include ANX105, a monoclonal antibody being developed for neurodegenerative indications, and ANX1502, an oral small molecule under investigation for specific autoimmune conditions.
