Developing a New Approach to Treat Rare, Autoimmune Conditions

Plasmacytoid dendritic cells or pDCs are immune cells that help the body fight infections but in certain chronic autoimmune condition these cells can become continuously activated and cause the body to attack itself. Horizon Therapeutics is developing an experimental monoclonal antibody known as daxdilimab that can get certain immune cells to deplete the pDC and shut down chronic inflammation in these conditions. We spoke to Jodi Karnell, senior director of Research at Horizon Therapeutics, about the role of pDCs in certain autoimmune conditions, how daxdilimab works, and why it may offer a way to address a range of rare autoimmune condition for which there are no approved therapies or that are poorly addressed by existing treatment options.
