Safety, Efficacy, Pharmacokinetics, Pharmacodynamics of ACZ885 in Patients With NALP3 Mutations and Clinical Symptoms


This study will investigate the clinical efficacy, safety, pharmacokinetics (PK) and pharmacodynamics (PD) of ACZ885, administered intravenously and subcutaneously to patients with NALP3 mutations whose clinical symptoms are either untreated or insufficiently treated and require medical intervention.

Clinical Trial Outcome Measures

Primary Measures

  • Response to treatment and time to relapse after ACZ885 administration according to monthly investigator’s clinical assessments, laboratory monitoring, and patient diaries.
    • Time Frame: Every month
