People who have a certain type of slow-growing non-Hodgkin's lymphoma may benefit from Bexxar. This medication works to slow down the progression of this cancer by binding to proteins on a certain type of white blood cell, marking the cells for destruction by the immune system. This drug is approved for use in adults age 18 and older.
What Is Bexxar Used For?Bexxar® (tositumomab) is a prescription medication approved to treat certain types of non-Hodgkin's lymphoma, a type of cancer that starts in lymphocytes (a type of white blood cell). This medication is reserved for use when the cancer has come back (relapsed) or is not responding to other treatment (refractory).
There are several different types of non-Hodgkin's lymphoma. The types can be characterized by the kind of lymphocyte affected -- B-cells or T-cells. B-cell lymphoma is more common than T-cell lymphoma.
The types of non-Hodgkin's lymphoma can also be divided based on how quickly the cancer grows and spreads. Aggressive lymphomas (also called high-grade) are fast-growing, requiring treatment early on. Indolent lymphomas (also called low-grade), on the other hand, grow more slowly and may not need to be treated for years.
In some cases, non-Hodgkin's lymphoma may change from a slow-growing to a fast-growing form. In these cases, the cancer is said to have transformed.
Bexxar is approved to treat people with slow-growing, follicular or transformed non-Hodgkin's lymphoma that expresses a certain antigen known as the CD20 antigen. Follicular lymphoma is a common form of slow-growing B-cell non-Hodgkin's lymphoma.
