Description: Ibrutinib, also known as PCI-32765, is a potent and orally active BTK inhibitor. Ibrutinib binds to and inhibits BTK activity, preventing B-cell activation and B-cell-mediated signaling and inhibiting the growth of malignant B cells that overexpress BTK. Ibrutinib was approved by the US FDA on November 13, 2013 for the treatment of mantle cell lymphoma.

Additional Information

Ibrutinib is a potent covalent kinase inhibitor that targets BTK. BTK, or Bruton's tyrosine kinase, is an obvious target for therapy of B cell diseases because inactivating mutations lead to B cell aplasia in humans and the disease X-linked agammaglobulinemia. Ibrutinib has modest cytotoxicity against CLL cells in vitro but also blocks trophic stimuli from the microenvironment. As with other inhibitors of the BCR pathway, ibrutinib causes rapid nodal reduction and response associated with rapid increase in lymphocytosis, which then returns to baseline over time. The ORR of ibrutinib in relapsed refractory CLL is 67 % with PFS 88 % at 15 months. In a cohort of untreated patients 65 years and over, the estimated 15 month PFS is 96 %. Registration trials have been initiated, and the difficult task that remains is to determine where in the course of CLL therapy this drug will have the greatest impact and benefit for patients.
