The U.S. Food and Drug Administration today expanded the approved use of Imbruvica (ibrutinib) to treat patients with chronic lymphocytic leukemia (CLL) who carry a deletion in chromosome 17 (17p deletion), which is associated with poor responses to standard treatment for CLL. Imbruvica received a breakthrough therapy designation for this use.
The FDA is also approving new labeling to reflect that Imbruvica’s clinical benefit in treating CLL has been verified. In February 2014, Imbruvica received accelerated approval to treat CLL based on its effect on overall response rate. New clinical trial results examining progression-free survival and overall survival have confirmed the drug’s clinical benefit.
A type of non-Hodgkin lymphoma, CLL is a rare blood and bone marrow disease that usually gets worse slowly over time, causing a gradual increase in white blood cells called B lymphocytes, or B cells. The National Cancer Institute estimates that 15,720 Americans will be diagnosed and 4,600 will die from CLL in 2014. Imbruvica works by blocking the enzyme that allows cancer cells to grow and divide.
