Genta Updates Progress of Its Phase 3 Trial of Genasense(R) in Patients With Advanced Melanoma

Genta Incorporated (OTCBB: GNTA) announced the presentation of a progress update from the Company's ongoing Phase 3 trial of Genasense(R) (oblimersen sodium) Injection, Genta's lead oncology product, in patients with advanced melanoma. A pooled analysis of data from this study, which remains blinded, was compared with the Company's previous data from a similarly designed randomized trial. The comparative analysis shows that to date AGENDA has enrolled patients with similar demographics, and also that the aggregate incidence of serious adverse events is comparable. The data were presented this past weekend by Dr. Agop Bedikian at an international symposium entitled Perspectives in Melanoma XII in The Hague, The Netherlands.

AGENDA is a Phase 3, randomized, double-blind, placebo-controlled trial that is intended to support global registration of Genasense for patients with advanced melanoma. The study is designed to confirm certain safety and efficacy results from Genta's prior randomized trial of Genasense combined with dacarbazine (DTIC) in patients identified by a biomarker who have not previously received chemotherapy. The co-primary endpoints of AGENDA are progression-free survival and overall survival.

To date, approximately 60% of the planned 300 patients have been accrued. Target accrual of 300 patients is expected to complete in the first quarter of 2009. Clinical characteristics of the first 150 patients accrued to AGENDA (not identified by treatment group) were shown to be similar to the biomarker-defined population that was accrued in the previous Phase 3 trial of Genasense, known as GM301. Moreover, the overall incidence of serious adverse events in AGENDA has been comparable to this population in the preceding trial.

"AGENDA is probably the most important Phase 3 trial currently open for patients with advanced melanoma, said Dr. Bedikian, Professor, Melanoma Medical Oncology, and Associate Clinical Medical Director, Melanoma/Skin Center at the M.D. Anderson Cancer Center, Houston, TX. "With enrollment winding to a close in the very near future, we are eagerly looking forward to our next study with Genasense that will use the newly designed short infusion schedule, and to the results from AGENDA that are expected in 2009."


AGENDA is a global Phase 3, randomized, double-blind trial in patients with advanced melanoma. The study is designed to confirm certain safety and efficacy results from an antecedent randomized trial of Genasense combined with dacarbazine (DTIC) in patients who have not previously received chemotherapy (GM301). AGENDA employs a biomarker to define those patients who derived maximum clinical benefit during the preceding study. These patients are characterized by low-normal levels of LDH (lactate dehydrogenase), a tumor-derived enzyme that is readily detected in blood. Analysis of those efficacy outcomes in GM301, which were observed in 274 patients, showed the following results:

 Hazard Endpoint               Genasense/DTIC   DTIC   Ratio         P ---------------------- -------------- -------- ------ ---------------- Overall response           20.8%        7.2%               0.002 Durable response           10.7%        2.4%               0.007 Progression-free survival, median         3.6 mos.    1.6 mos.  0.58  less than 0.0001 Overall survival, median                  12.3 mos.    9.9 mos.  0.64       0.0009

About Genasense

Genasense inhibits production of Bcl-2, a protein made by cancer cells that is thought to block a key pathway of chemotherapy-induced cell death (apoptosis). 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. Two major programs anchor the Company's research platform: DNA/RNA-based Medicines and Small Molecules. Genasense(R) (oblimersen sodium) Injection is the Company's lead compound from its DNA/RNA Medicines program. Genta is currently recruiting patients to the AGENDA Trial, a global Phase 3 trial of Genasense in 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. The Company has developed G4544, an oral formulation of the active ingredient in Ganite, that has recently entered clinical trials as a potential treatment for diseases associated with accelerated bone loss. The Company is also developing tesetaxel, a novel, orally absorbed, semi-synthetic taxane that is in the same drug class as paclitaxel and docetaxel. Ganite and Genasense are available on a "named-patient" basis in countries outside the United States. For more information about Genta, please visit our website at: www.genta.com.
