How Does Acthar Work? Treats autoimmune conditions across a variety of organ systems Appears to modulate the immune system and associated inflammatory response through binding to melanocortin receptors Activity extends beyond steroidogenesis – Acthar binds to all 5 melanocortin receptors (MC1R-5R) found on immune cells and cells in many of the targeted tissues (e.g., kidney podocytes) 1,3,5,6,8,9 – Acthar also triggers the production of cortisol and other adrenal compounds through binding to MC2R receptors found in the adrenal cortex Acthar components have yet to be fully characterized – ACTH is the primary active component in Acthar, but there may be others Mechanism(s) of action not yet fully understood Treats autoimmune conditions across a variety of organ systems Appears to modulate the immune system and associated inflammatory response through binding to melanocortin receptors Activity extends beyond steroidogenesis – Acthar binds to all 5 melanocortin receptors (MC1R-5R) found on immune cells and cells in many of the targeted tissues (e.g., kidney podocytes) 1,3,5,6,8,9 – Acthar also triggers the production of cortisol and other adrenal compounds through binding to MC2R receptors found in the adrenal cortex Acthar components have yet to be fully characterized – ACTH is the primary active component in Acthar, but there may be others Mechanism(s) of action not yet fully understood 1 Arnason et al.
