NLRC4-MAS Clinical Trial
Official title:
Multicenter, Double-blind, Placebo-controlled, Randomized Withdrawal Trial With Tadekinig Alfa (r-hIL-18BP) in Patients With IL-18 Driven Monogenic Autoinflammatory Conditions: NLRC4 Mutation and XIAP Deficiency
This is a Phase 3 study to assess the safety and efficacy of Tadekinig alfa in patients with monogenic, interleukin-18 (IL 18) driven autoinflammation due to Nucleotide-binding oligomerization domain, leucine-rich repeat and caspase recruiting domain (CARD domain) containing 4 (NLRC4) - Macrophage activation syndrome (MAS) mutation (NLRC4-MAS mutation) or X-linked inhibitor of apoptosis (XIAP) deficiency. Because of the likelihood for pathogenic IL-18 in certain monogenic diseases, patients known to harbor deleterious mutations in NLRC4-MAS or XIAP and who have a history of ongoing inflammation will be enrolled if they have ferritin ≥ 500 ng/mL or persistent C reactive protein (CRP) elevation ≥ 2 times the upper limit of normal (ULN) and the patients should have a Modified Autoinflammatory Disease Activity Index (mAIDAI) ≥ 4.
The study is designed with single-arm, open-label phase (SAOL) of Tadekinig alfa treatment duration for 18-week followed by an up to 16-week Randomized Withdrawal (RW) period for efficacy and safety evaluation, with no interruption between the two phases of treatment. The screening period will occur before the SAOL phase and before the first dose of Investigational Medicinal Product (IMP) ;
