Immune cell modulators are a novel therapeutic class with the potential to deliver differentiated outcomes in autoimmune and inflammatory diseases including dermatology, gastroenterology, and rheumatology
-
Targeting co-inhibitory receptors may drive broad immunological outcomes to bring the immune system back to homeostasis
-
Rosnilimab (PD-1 depleter and agonist) specifically targets activated T cells:
- Depleting PD-1high T cells
- Reduce T cell migration, proliferation & cytokine secretion
- Reduce plasma cell generation & autoantibody levels
-
Membrane-proximal binding epitope and optimized Fc receptor binding affinity enables tight immune synapse and best-in-class potency
