ILARIS® is a recombinant human monoclonal IgG1/κ antibody that selectively neutralizes interleukin-1β (IL-1β), a proinflammatory cytokine central to innate immune dysregulation. By binding IL-1β, it inhibits interaction with IL-1 receptors, thereby attenuating inflammation. ILARIS does not cross-react with IL-1α or IL-1 receptor antagonist (IL-1ra). It is approved for autoinflammatory syndromes driven by excessive IL-1β activity, including CAPS, TRAPS, HIDS/MKD, FMF, Still’s disease, and acute gout flares refractory to conventional therapies.
ILARIS is supplied as a 150 mg/mL sterile solution for subcutaneous injection in single-dose vials. Dosing frequency varies by indication: every 8 weeks for CAPS, every 4 weeks for TRAPS/HIDS/MKD/FMF/Still’s disease, and as a single dose for gout flares (minimum 12-week interval between doses). Contraindications include hypersensitivity to canakinumab or excipients. Warnings emphasize serious infections (e.g., tuberculosis reactivation, opportunistic pathogens), hypersensitivity reactions (including DRESS), and avoidance of live vaccines. Pre-treatment screening for latent infections and close monitoring during therapy are critical.
