Clin Transl Sci. 2019

In this first in-human phase I, double-blind, placebo-controlled trial, the Bruton’s tyrosine kinase (BTK) inhibitor evobrutinib was well-tolerated, showed linear and time-independent PK, induced long-lasting BTK inhibition, and was not associated with prolongation of QT/QTc interval in healthy subjects. Evobrutinib is an oral BTK inhibitor that has demonstrated efficacy in pre-clinical and autoimmune disease models. BTK is a key regulator of B cell receptor and Fc receptor signalling, an...

BTK is involved in both adaptive and innate immune responses and mediates signalling of several immune receptors of relevance to RA and SLE pathogenesis. Targeting BTK is a promising approach therefore for autoimmune disorders with aberrant B cell responses. Evobrutinib is a novel, highly specific, and irreversible BTK inhibitor. In vivo and animal models showed that evobrutinib modulated B cell and innate immune cell activation, was efficacious, and prevented joint damage. The potency of evob...
