ASLAN is a pharmaceutical company that develops novel medicines for global markets. The firm's portfolio is led by eblasakimab (ASLAN004), a potential human monoclonal antibody that binds to the IL-13 receptor a1 subunit (IL-13Ra1), blocking signaling of two pro-inflammatory cytokines, IL-4 and IL-13, which are central to triggering symptoms of atopic dermatitis, such as redness and itching of the skin. The company is conducting a Phase II b clinical trial investigating eblasakimab as a therapeutic antibody for moderate-to-severe atopic dermatitis (AD). The firm is also developing farudodstat (ASLAN003), an orally active, potent inhibitor of human dihydroorotate dehydrogenase (DHODH) that has the potential to be a therapy for autoimmune disease. The firm is also focused on developing antagonists of the aryl hydrocarbon receptor (AhR), an immune checkpoint inhibitor, through a joint venture.
