TREMFYA® is the first and only fully-human, dual-acting monoclonal antibody approved to treat PsA that blocks IL-23 while also binding to CD64, a receptor on cells that produce IL-23. IL-23 is a cytokine secreted by activated monocyte/macrophages and dendritic cells that is known to be a driver of immune-mediated diseases including active PsA. Editor's Notes: a) ACR20 response is defined as both at least 20 percent improvement from baseline in the number of tender and number of swollen joints, and a 20 perc ...
