BERKELEY HEIGHTS, N.J., Feb. 2 /PRNewswire-FirstCall/ -- Genta Incorporated today announced that the Company has completed its response to the 180-day List of Outstanding Issues from the European Medicines Agency (EMEA) regarding its Marketing Authorization Application (MAA) for Genasense(R) (oblimersen sodium), its lead anticancer product, for treatment of patients with advanced melanoma. The Company currently anticipates that EMEA's Committee on Human Medicinal Products (CHMP) will complete its review and issue its opinion regarding approval within the next 90 days. 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 resistance to cancer treatment. By knocking down Bcl-2 in cancer cells, Genasense may enhance the effectiveness of chemotherapy in patients with advanced melanoma. A summary of data from the final analysis of the pivotal Phase 3 trial of Genasense appears below. Efficacy The MAA is based on long-term data derived from the largest randomized controlled trial that has ever been conducted in patients with advanced melanoma. In this trial, which was conducted at 139 sites in 9 countries, 771 patients were randomly assigned to receive chemotherapy with dacarbazine (DTIC) alone or in combination with Genasense. The submission includes data compiled after 24-months of minimum follow-up on all patients. Unless otherwise noted, these results were based on an intent-to-treat analysis: Endpoint Genasense/DTIC DTIC P Overall response 13.5 % 7.5 % 0.007 Complete response 2.8 % 0.8 % 0.03 Durable response 7.3 % 3.6 % 0.03 Progression-free survival, 2.6 mos. 1.6 mos. 0.0007 median Overall survival, median 9.0 mos. 7.8 mos. 0.077 Prior to randomization, patients were prospectively stratified according to certain risk factors, including elevated blood levels of an enzyme known as LDH -- a factor that previous studies have shown is strongly associated with poor outcome. The final analysis has shown that LDH was the sole stratification factor significantly associated with a treatment interaction. When this treatment effect was evaluated, the efficacy of Genasense was significantly superior for all major efficacy outcomes in patients who had normal LDH at baseline, a group that comprised approximately two-thirds of patients in the trial (N=508). In this group, the following efficacy results were observed: Endpoint Genasense/DTIC DTIC P Overall response 17.2 % 9.3 % 0.009 Complete response 3.4 % 0.8 % 0.04 Durable response 9.6 % 4.0 % 0.014 Progression-free survival, 3.1 mos. 1.6 mos. 0.0007 median Overall survival, median 11.4 mos. 9.7 mos. 0.018 Safety In the randomized trial, the most frequent serious adverse events that occurred in greater than or equal to 5% of patients were fever and disease progression (6.2% vs. 2.8%, and 5.1% vs. 4.7%, respectively, for Genasense/DTIC compared with DTIC alone). The most frequent Grade 3 or 4 adverse events that occurred in greater than or equal to 5% of patients were neutropenia (21.3% vs. 12.5%), thrombocytopenia (15.9% vs. 6.4%), leukopenia (7.5% vs. 3.9%), anemia (7.3% vs. 4.7%), and nausea (6.7% vs. 2.5%). Although there was an increase in discontinuations due to adverse events in the Genasense arm (19% vs. 11%), there was no difference in the number of fatal, treatment-emergent adverse events (i.e., events that lead to a death on study or within 30 days from last study treatment). Data from this trial were recently published in the Journal of Clinical Oncology and can be accessed at: . About Malignant Melanoma Malignant melanoma is the most deadly form of skin cancer. Melanoma is responsible for more than 90% of all skin cancer deaths. The European Network of Cancer Registries estimates that more than 60,000 cases of melanoma are diagnosed each year. The incidence of this disease is increasing by approximately 4 percent annually in the U.S., where it is the number one cause of cancer deaths for women aged 25 to 29. Additional information about melanoma can be accessed at: . 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. About Genta Genta Incorporated is a biopharmaceutical company with a diversified product portfolio that is focused on delivering innovative products for the treatment of patients with cancer. The Company's research platform is anchored by two major programs that center on oligonucleotides (RNA- and DNA- based medicines) and small molecules. Genasense(R) (oblimersen sodium) Injection is the Company's lead compound from its oligonucleotide program. Genta has completed a pending Marketing Authorization Application to the European Medicines Agency (EMEA) for use of Genasense plus dacarbazine for treatment of patients with advanced melanoma. The leading drug in Genta's small molecule program is Ganite(R) (gallium nitrate injection), which the Company is exclusively marketing in the U.S. for treatment of symptomatic patients with cancer related hypercalcemia that is resistant to hydration.
