Used in the treatment of autoimmune and inflammatory diseases by targeting the interleukin-6 receptor, thereby inhibiting IL-6 signaling pathways involved in chronic inflammation and immune activation. Investigated for conditions such as rheumatoid arthritis, cytokine release syndrome, and certain cancers where IL-6 plays a role in disease progression. Enables modulation of excessive immune responses, making it a candidate for managing hyperinflammatory states, including those seen in severe infections or immunotherapies.
