Evidence summary
First oral small-molecule NLRP3 inhibitor to reach clinical trials. Directly binds NLRP3 NACHT domain, preventing inflammasome assembly. Phase I showed favorable safety profile without hepatotoxicity seen with MCC950. Could represent paradigm shift from injectable biologics to oral therapy if proven effective in CAPS.
