Biological Activity

Orelabrutinib (ICP-022) is a potent, selective, orally active, and irreversible Bruton's tyrosine kinase (BTK) inhibitor with IC50 of 1.6 nM.
Orelabrutinib (ICP-022) displays high selectivity at 1 μM against a panel of 456 kinases, only targets BTK with >90% inhibition lacking inhibition on many additional kinases, including EGFR, TEC, and bone marrow tyrosine kinase.
Orelabrutinib (ICP-022) inhibited B cell lymphoma cell proliferation in vitro (TMD8 cell, IC50=0.08 uM).
Orelabrutinib (ICP-022) lacked inhibition on cellular ITK compared with ibrutinib.
Orelabrutinib (ICP-022) preserved rituximab-mediated cytotoxicity, the combination of orelabrutinib and rituximab treatment enhanced NK-cell-mediated ADCC.
Orelabrutinib (ICP-022) combined with rituximab effectively inhibited tumor growth in animal models.
