About Mantle Cell LymphomaMCL is an aggressive type of B-cell non-Hodgkin lymphoma (NHL) that usually occurs in older adults. The disease typically begins in the lymph nodes but can spread to other tissues, such as bone marrow and liver. Ibrutinib targets the B-cell receptor pathway an important pathway in malignant B-cell growth and proliferation. In the United States there are approximately 5,000 new cases of MCL each year.
About Waldenstrom's macroglobulinemia Waldenstrom's macroglobulinemia is rare type of lymphoma. The disease begins with a malignant change to the B-cell during its maturation so that it continues to reproduce more malignant B-cells resulting in an overproduction of monoclonal immunoglobulin M antibody (IgM). WM is a hematologic malignancy for which no established standard of care - or approved therapeutic exists. In the United States there are approximately 1,500 new cases each year.
About IbrutinibIbrutinib is an investigational drug designed to specifically target and selectively inhibit an enzyme called Bruton's tyrosine kinase (BTK). BTK is a key mediator of at least three critical B-cell pro-survival mechanisms occurring in parallel – regulating apoptosis, adhesion, and cell migration and homing. Through these multiple actions, BTK helps to direct malignant B-cells to lymphoid tissues, thus allowing access to a micro environment necessary for survival.The effectiveness and safety of ibrutinib alone or in combination with other treatments is being studied in several B-cell malignancies, including chronic lymphocytic leukemia/small lymphocytic lymphoma, mantle cell lymphoma, diffuse large B-cell lymphoma, follicular lymphoma, Waldenstrom's macroglobulinemia and multiple myeloma. To date five Phase III trials have been initiated with ibrutinib and a total of 27 trials are currently registered on clinicaltrials.gov.
