Ibrutinib (Maintenance)

Prof. Dr. M. Dreyling (co-chairman) · Phase 3 active Small molecule

Ibrutinib is a Bruton's tyrosine kinase (BTK) inhibitor that blocks BTK signaling in B cells and other immune cells, reducing their proliferation and survival.

Ibrutinib is a Bruton's tyrosine kinase (BTK) inhibitor that blocks BTK signaling in B cells and other immune cells, reducing their proliferation and survival. Used for Chronic lymphocytic leukemia (CLL) — maintenance therapy, Mantle cell lymphoma (MCL) — maintenance therapy, Waldenstrom macroglobulinemia — maintenance therapy.

Mechanism of action

Ibrutinib covalently binds to BTK, a key enzyme in the B-cell receptor signaling pathway. By inhibiting BTK, it prevents B-cell activation, proliferation, and migration, leading to reduced tumor cell survival in B-cell malignancies. In maintenance therapy, continued BTK inhibition helps prevent disease relapse and progression.
