Abstract
Tirabrutinib
(Velexbru®) is an orally administered, small molecule, Bruton's
tyrosine kinase (BTK) inhibitor being developed by Ono Pharmaceutical and its
licensee Gilead Sciences for the treatment of autoimmune disorders and
haematological malignancies. Tirabrutinib irreversibly and covalently binds to
BTK in B cells and inhibits aberrant B cell receptor signalling in B
cell-related cancers and autoimmune diseases. In March 2020, oral tirabrutinib
was approved in Japan for the treatment of recurrent or refractory primary
central nervous system lymphoma. Tirabrutinib is also under regulatory review
in Japan for the treatment of Waldenström's
macroglobulinemia and lymphoplasmacytic lymphoma. Clinical development is
underway in the USA, Europe and Japan for autoimmune disorders, chronic
lymphocytic leukaemia, B cell lymphoma, Sjogren's syndrome, pemphigus and
rheumatoid arthritis. This
article summarizes the milestones in the development of tirabrutinib leading to
the first approval of tirabrutinib for the treatment of recurrent or refractory
primary central nervous system lymphoma in Japan.
