Therapeutic Use of Tadekinig Alfa in Adult-onset Still's Disease

Summary

The objective of this study is to assess safety, tolerability and early signs of efficacy of the investigational drug Tadekinig alfa in Adult-onset Still's disease, a rare polygenic auto-inflammatory disorder for which treatment remains empirical. This disease is characterized by a daily spiking fever, arthralgia / arthritis, and skin rashes with frequent components of sore throat, lymphadenopathies and neutrophilic leukocytosis. The etiology is unknown. In addition to the above-mentioned clinical features, the diagnosis includes some laboratory components that reflect the systemic inflammation: high erythro-sedimentation rate, C-reactive protein, high serum ferritin and high levels of interleukin 18 (IL-18). Tadekinig alfa is the drug name for recombinant human interleukin-18 binding protein (IL-18BP). This investigational drug was tested in healthy volunteers, psoriasis and rheumatoid arthritis patients in phase I studies. It demonstrated good safety and tolerability profile with only mild adverse events in the injection site.
