Mechanism of Action
In systemic lupus erythematosus, the body can produce a great amount of type 1 interferon, which activates the immune system excessively and creates problems for lupus patients. Anifrolumab acts to block IFN-1 from sending signals to other immune cells, which prevents the body from being attacked by itself.
