Background

Branebrutinib is a covalent inhibitor of Bruton’s tyrosine kinase (BTK; IC₅₀ = 0.1 nM).¹ It is greater than 5,000-fold selective for BTK over a panel of 240 kinases but does inhibit the additional Tec family kinases Tec, BMX, and TMX (IC₅₀s = 0.9, 1.5, and 5 nM, respectively). Branebrutinib inhibits calcium flux in Ramos B cells induced by B cell receptor (BCR) stimulation (IC₅₀ = 7.2 nM), as well as BCR stimulation-induced proliferation of, and CD86 surface expression in, peripheral B cells (IC₅₀s = 0.04 and 0.3 nM, respectively). It inhibits TNF-α production in human peripheral blood mononuclear cells (PMBCs) induced by Fcγ receptor stimulation (IC₅₀ = 0.3 nM). Branebrutinib (0.5 mg/kg) is completely protective against bone destruction in a mouse model of collagen-induced arthritis. It also reduces proteinuria and glomerular IgG immune complex deposition and increases survival in an NZB/W lupus-prone mouse model.
