Genta Incorporated Release: Genasense(R) Data in Melanoma to be Presented

BERKELEY HEIGHTS, N.J., Sept. 5 /PRNewswire-FirstCall/ - Genta Incorporated announced that data from the Company’s Phase 3 trial of Genasense(R) (oblimersen sodium) plus chemotherapy would be presented at the opening session of the first Worldwide Melanoma Center Meeting organized by the European Association of Dermato-Oncology (EADO). Genta, which is a Silver Level sponsor of the EADO meeting, will also host its key investigator meeting for European participants in the Company’s ongoing Phase 3 trial of Genasense in advanced melanoma. The Genasense clinical results will be presented by Dr. Claus Garbe, who is Chair of the Congress, and Professor of Dermatology and Head of the Division of Dermatooncology, Department of Dermatology, University Medical Center, Tubingen, Germany. The EADO, which is the lead international cooperative group for the current Phase 3 trial, is meeting this week in Barcelona, Spain.

The new Genasense trial, known as AGENDA, is a randomized, double-blind, placebo-controlled study in which patients are randomly assigned to receive Genasense plus dacarbazine (DTIC) or DTIC alone. AGENDA is designed to confirm the safety and efficacy of Genasense when combined with DTIC in patients who have not previously received chemotherapy. The trial will accrue approximately 300 patients who have been defined using a biomarker and will be conducted at approximately 100 sites worldwide, including North America, Europe and Australia. Patient enrollment into AGENDA has been initiated.

About Genasense in Advanced Melanoma

Genasense, Genta’s lead anticancer drug, is a novel targeted therapy that blocks the production of Bcl-2, a protein that appears to be a fundamental cause of cancer treatment resistance. By knocking down Bcl-2, Genasense may enhance the effectiveness of chemotherapy in patients with advanced melanoma. Genasense in melanoma has Orphan Drug designations in Australia and the U.S., along with Fast Track designation in the U.S.

In its initial Phase 3 trial, Genta performed the largest randomized controlled trial that has ever been conducted in patients with advanced melanoma. In that trial, 771 patients were randomly assigned to receive chemotherapy with DTIC alone or in combination with Genasense. A scientific article that describes efficacy and safety results from this study can be accessed at: http://www.jco.org/cgi/content/abstract/JCO.2006.06.0483v1.

In that trial, patients were prospectively stratified according to levels of a blood enzyme known as LDH. Further analysis of this study showed that maximum benefit accrued to patients whose LDH biomarker did not exceed 80% of the upper limit of normal. Efficacy results in this group of 274 patients, which are the focus of the confirmatory AGENDA trial, are displayed in the table below. (The hazard ratios indicate that the addition of Genasense to DTIC was associated with a 42% reduction in the risk of disease progression and a 36% reduction in risk of death.)

About Melanoma

Malignant melanoma is the most deadly form of skin cancer. The incidence of this disease is increasing by approximately 4% annually in the U.S. In 2004, the American Cancer Society estimates more than 55,000 cases of malignant melanoma will have been diagnosed. Melanoma is the number one cause of cancer death in women aged 25 to 29. More information about melanoma can be accessed at the Melanoma Research Foundation: http://www.melanoma.org.
