Genta Completes Appeal of FDA Decision for Genasense...(months; P 0.05) A scientific report ...)

A scientific report of the safety and efficacy findings from this pivotal study was published earlier this year in the Journal of Clinical Oncology (25:1114, 2007).

Safety

Grade 3 or Grade 4 adverse events that occurred during treatment or within 30 days from last treatment in an increased percentage of patients in the Genasense group included, but were not limited to, thrombocytopenia, nausea, and intravenous-catheter complications. Adverse events resulted in discontinuation of therapy in an equal percentage of patients in both groups. Nine patients in the Genasense group and 5 patients in the chemotherapy-alone group had adverse events that resulted in death, including two patients in the Genasense group who died from complications associated with tumor lysis and infusion-related reactions.

About Chronic Lymphocytic Leukemia

CLL is the most common form of leukemia in adults. According to the American Cancer Society, approximately 8,000 patients will be diagnosed this year. More than 60,000 people in the U.S. currently have CLL. The disease arises in lymphocytes, a type of white blood cell that normally produces antibodies and serves important immune functions. Patients with CLL typically develop symptoms that may progress over a period of years, ultimately producing a generalized depression of immunity, marked increases in the size of spleen, liver and lymph nodes, and impaired production of other normal blood cells. Eventually, these problems may cause life-threatening complications, such as overwhelming infections and fatal bleeding. More information about CLL can be accessed at the website for the Lymphoma Research Foundation at: http://www.lymphoma.org.
