Lymphoma is cancer of the lymphatic system that begins with a change in the lymphocytes, impairing the ability of the body's immune system to fight infection. Lymphomas are divided into two categories: Hodgkin lymphoma and non-Hodgkin lymphoma. Most non-Hodgkin lymphomas are B-cell lymphomas, which are further classified into 14 different sub-types based on the stage of cell development during which the B cell has been affected. The rest are T-cell lymphomas, which affect another type of white blood cell. There are approximately 66,000 new cases of lymphoma and nearly 20,000 deaths each year in the United States according to the National Cancer Institute.

Results of the first clinical study examining the use of fostamatinib disodium, an investigational treatment that targets a protein called SYK (spleen tyrosine kinase), showed that the new agent represents a safe and novel therapeutic approach that should be further developed for the treatment of B-cell non- Hodgkin lymphoma. In the study, fostamatinib disodium, administered as a tablet, produced significant responses in patients who had failed previous treatments for diffuse large B-cell lymphoma, chronic lymphocytic leukemia, and small lymphocytic lymphoma, as well as prolonged stable disease in patients with follicular lymphoma.
Following a phase I dose-limiting study of 13 patients, the regimen of a 200 mg twice-daily dose of fostamat
