Used in the treatment of autoimmune diseases such as psoriasis, psoriatic arthritis, and ankylosing spondylitis by neutralizing IL-17A, a pro-inflammatory cytokine involved in chronic inflammation. This antibody helps reduce inflammation, slow disease progression, and improve symptoms by blocking the interaction of IL-17A with its receptor. It serves as a reference in developing biosimilars and evaluating new anti-IL-17 therapies. Also utilized in preclinical research to study IL-17 pathway mechanisms and validate therapeutic targets.
