Additional details about the conference can be found at: http://www.hematology.org/About Multiple Myeloma Multiple myeloma is an incurable cancer of plasma cells, a type of white blood cell derived from B-lymphocytes, normally responsible for the production of antibodies. Malignant plasma cells accumulate in the bone marrow leading to bone lesions and interfering with the production of normal white blood cells. Median survival time from first treatment is 2½ to 5 years depending on disease stage at diagnosis. In the United States there are almost 20,000 newly diagnosed cases of multiple myeloma annually and a total of approximately 65,000 patients with the disease. Senesco was previously granted orphan drug status for SNS01-T, the Company’s lead drug candidate for treatment of multiple myeloma. About Senesco Technologies, Inc.
