Johnson & Johnson, Pharmacyclics, Inc. Gets New Breakthrough-Therapy Designation for Ibrutinib
"Ibrutinib continues to demonstrate promise for patients living with B-cell malignancies, and we are pleased that the FDA has recognized its potential for people living with CLL and the del17p mutation," said Peter F. Lebowitz, M.D., Ph.D., Global Oncology Therapeutic Area Head, Janssen. "This third Breakthrough Therapy Designation reflects the potential importance of ibrutinib for patients diagnosed with a 17p deletion chromosomal abnormality in CLL/SLL, and we are committed to working with Pharmacyclics and the FDA to expedite development and review of ibrutinib as quickly as possible."
The implications of Breakthrough Therapy Designation cannot be determined at this time. Janssen and Pharmacyclics are working with the FDA to determine any potential implications of the Breakthrough Therapy Designation to the ongoing and planned development activities.
In February 2013, FDA granted Breakthrough Therapy Designations for ibrutinib as a monotherapy for two B-cell malignancies: in patients with relapsed or refractory Mantle cell lymphoma (MCL) who have received prior therapy, and in patients with Waldenstrom's macroglobulinemia (WM). Enacted as part of the 2012 FDA Safety and Innovation Act (FDASIA), Breakthrough Therapy Designation is intended to expedite the development and review time for a potential new medicine "to treat a serious or life-threatening disease or condition and preliminary clinical evidence indicates that the drug may demonstrate substantial improvement over existing therapies on one or more clinically significant endpoints, such as substantial treatment effects observed early in clinical development."[1]
About Chronic Lymphocytic Leukemia and Small Lymphocytic Lymphoma
Chronic Lymphocytic Leukemia (CLL) is a slow-growing cancer of the white blood cells (lymphocytes), most commonly B-cells. CLL is the most common adult leukemia.[2] The genetic mutation 17p occurs when part of chromosome 17has been lost. CLL patients with 17p deletion have poor treatment outcomes.[3]17p deletion is reported in seven percent of CLL cases at diagnosis,[4] with approximately 20 to 40% of relapsed or refractory patients harboring the mutation.[5]Small Lymphocytic Lymphoma (SLL) is a slow-growing lymphoma in which too many immature white blood cells cause lymph nodes to become larger than normal.[6]
About Ibrutinib
Ibrutinib was 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 microenvironment 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 30 trials are currently registered on clinicaltrials.gov.
Janssen Biotech, Inc. and Pharmacyclics entered a collaboration and license agreement in December 2011 to co-develop and co-commercialize ibrutinib.
