Mechanism of action

ACE-536 binds to activin type II receptors, blocking activin signaling which normally suppresses red blood cell production. By inhibiting this negative regulator of erythropoiesis, the drug stimulates the bone marrow to produce more red blood cells, thereby increasing hemoglobin and reducing anemia. This mechanism is distinct from traditional erythropoiesis-stimulating agents (ESAs) as it works through a different pathway.
