About Ofirnoflast (HT-6184)

关于Ofirnoflast（HT-6184）

Ofirnoflast is Halia's first-in-class, oral, allosteric NEK7 inhibitor designed to modulate NLRP3 inflammasome activation upstream of inflammatory signaling. By targeting NEK7 before NLRP3 assembly, ofirnoflast prevents inflammasome formation and disrupts a key pathway implicated in ineffective hematopoiesis.
