“Caplacizumab Resistance in Immune Thrombotic Thrombocytopenic Purpura (iTTP) Associated with VWF A1 Domain Missense Variant
This landmark first report describes caplacizumab resistance in an iTTP patient caused by a VWF A1 domain missense variant (P1266L) that impairs drug binding, revealing a novel genetic mechanism of treatment failure beyond premature therapy discontinuation.”
