Ibrutinib Powder Description

Ibrutinib powder is a type of drug which was used alone or with other drugs to treat adults with chronic lymphocytic leukemia, small lymphocytic lymphoma, or Waldenstrom macroglobulinemia (a type of non-Hodgkin lymphoma). It is also used alone to treat adults with mantle cell lymphoma or marginal zone lymphoma who have received at least one other treatment. It is also being studied in the treatment of other types of cancer. Ibrutinib powder blocks a protein called Bruton’s tyrosine kinase (BTK), which may help keep cancer cells from growing. It is a type of tyrosine kinase inhibitor. Also called Imbruvica.


Ibrutinib Powder Mechanism of Action

Ibrutinib powder is a potent and irreversible inhibitor of Bruton’s tyrosine kinase (BTK), an integral component of the B-cell receptor (BCR) and cytokine receptor pathways. Constitutive activation of B-cell receptor signaling is important for survival of malignant B-cells; BTK inhibition results in decreased malignant B-cell proliferation and survival.


Ibrutinib Powder Application

Ibrutinib powder is approved in Europe for treating three types of lymphoma.


♦ Mantle cell lymphoma

For people whose lymphoma has relapsed (come back) or has not responded to treatment (refractory lymphoma). Ibrutinib powder is given on its own.


♦ Chronic lymphocytic leukaemia (CLL)

For people who have not yet had treatment for their CLL (first-line treatment). Ibrutinib powder can be given on its own or in combination with rituximab  or obinutuzumab (antibody therapies). For people whose CLL has relapsed after treatment. For people with relapsed CLL, ibrutinib powder can be given on its own or with bendamustine (a chemotherapy drug) and rituximab.


♦ Waldenström’s macroglobulinaemia (WM)

For people who have previously received other treatments for WM. For people who can’t have chemo-immunotherapy (chemotherapy with antibody therapy) as first-line treatment.

European approval to use ibrutinib powder in CLL and mantle cell lymphoma was granted in November 2014. It was then extended to WM in May 2015. In 2016, the European Medicines Agency (EMA) expanded ibrutinib powder’s recommended uses for CLL.

Ibrutinib powder is being tested in further clinical trials in people with these types of lymphoma. This is to see if ibrutinib powder could work better in combination with other treatments, such as chemotherapy or antibody therapy (for example, rituximab). It is also being tested in other types of lymphoma. Use our searchable database to see if there’s a clinical trial that might be suitable for you at Lymphoma TrialsLink.
