FDA Accepts Oblimersen's Amended New Drug Application

BERKELEY HEIGHTS, N.J., July 14 /PRNewswire-FirstCall/ -- Genta Incorporated (BULLETIN BOARD: GNTA) announced that the Food and Drug Administration (FDA) has accepted the Company's amendment to its New Drug Application (NDA) for Genasense(R) (oblimersen sodium) Injection as a "complete response". The NDA proposed the use of Genasense plus chemotherapy for patients with relapsed or refractory chronic lymphocytic leukemia (CLL). The recent submission was based on new information from the Company's completed, randomized Phase 3 trial that showed, among other findings, a significant increase in overall survival for patients who achieved a complete or partial response when treated with Genasense plus chemotherapy compared with patients treated with chemotherapy alone.

The amendment responds to a communication received in March 2008 from FDA's Center for Drug Evaluation and Research (CDER) that denied Genta's appeal of a prior "non-approvable" decision of the Genasense NDA in December 2006. That communication described a regulatory path forward that included but was not limited to determination of long-term survival in patients who entered the study. FDA has informed the Company that it considers Genta's complete response as a Class 2 resubmission with a Prescription Drug User Fee Act (PDUFA) goal date of December 3, 2008.

"We are pleased that the FDA will formally review this new information, and we look forward to working with FDA's Division of Oncology Drug Products during their consideration of this amendment," commented Dr. Loretta M. Itri, Genta's President, Pharmaceutical Development, and Chief Medical Officer.

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/.

About Genasense
Genasense inhibits production of Bcl-2, a protein made by cancer cells that is thought to block chemotherapy-induced apoptosis (programmed cell death). By reducing the amount of Bcl-2 in cancer cells, Genasense may enhance the effectiveness of current anticancer treatment. Genta is pursuing a broad clinical development program with Genasense evaluating its potential to treat various forms of cancer.
