Patient Accrual Completed into Phase 3 Trial of Genasense(R) in Patients with Acute Myeloid Leukemia

Large Cooperative Group Study Tests Efficacy in Previously Untreated Patients

BERKELEY HEIGHTS, N.J., Oct. 31 (HSMN NewsFeed) -- Genta Incorporated (Nasdaq: GNTA ) announced that target patient accrual has been completed into a randomized Phase 3 trial of Genasense plus chemotherapy in previously untreated patients with acute myeloid leukemia (AML). The trial was conducted by the Cancer and Leukemia Group B (CALGB), the largest U.S. oncology cooperative group, and was sponsored by the National Cancer Institute (NCI).

"There is a pressing need to identify new effective treatments in AML, particularly for high-risk patients, and we are highly gratified by the support of the clinical community in completing rapid accrual onto this trial," commented Loretta M. Itri, M.D., President of Pharmaceutical Development and Chief Medical Officer at Genta. "The Company believes a positive result from this trial may be sufficiently robust to support worldwide regulatory applications in AML. We look forward to evaluating these results with our colleagues in CALGB."

In this trial, all patients received standard chemotherapy with daunorubicin and cytarabine (ARA-C), and they were randomly assigned to receive Genasense or no additional therapy. Genasense was given during initial therapy (i.e., "induction") and in two additional chemotherapy cycles ("consolidation") after achieving complete remission (CR). This trial enrolled patients over the age of 59 who had not previously received chemotherapy. Due to the accumulation of additional genetic mutations, these patients are known to have an inferior outcome with standard chemotherapy, achieving lower rates of CR that result in shorter survival. The primary endpoint in the trial is a comparison of overall survival; secondary endpoints include percent CR, remission duration, safety, and other assessments. The CALGB has also conducted a number of correlative laboratory tests in this trial, including measurements of Bcl-2, the biochemical target of Genasense. A minimum target of 500 patients was prospectively specified for accrual, a goal that has now been reached. Data from this trial are expected in 2007.

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.
