Tesetaxel Results as Initial Chemotherapy for Women With Recurrent Breast Cancer to be Highlighted at ASCO
May 22, 2012 (GlobeNewswire via COMTEX) -- --Promising results for response and progression-free survival
--Company to proceed with randomized trial
BERKELEY HEIGHTS, N.J., May 22, 2012 (GLOBE NEWSWIRE) -- Genta Incorporated (GNTA) today announced results from the Company's Phase 2 clinical trial using tesetaxel as initial, single-agent chemotherapy in women with advanced breast cancer. The data will be formally presented at the upcoming annual meeting of the American Society of Clinical Oncology (ASCO) in Chicago, IL. Tesetaxel is the leading oral taxane in clinical development. The trial is lead by Memorial Sloan-Kettering Cancer Center, New York, NY, in collaboration with three other U.S. centers.
Women were eligible if they had not received chemotherapy for locally advanced or metastatic HER2-negative breast cancer. Prior adjuvant chemotherapy was allowed if the recurrence was at least 12 months from the last dose. Forty-six patients were accrued to the trial, and 44 are currently evaluable for response. Seventy percent of patients had received adjuvant chemotherapy; more than 80% of those regimens had included an injectable taxane. More than 50% of patients had received local radiotherapy, and approximately two-thirds had progressed on one or more hormonal therapies.
Major objective responses were observed in 20 of 44 patients (45%), including 1 complete response and 19 partial responses. Seven of the major responders cleared more than 75% of their measurable disease. The disease-control/clinical-benefit rate, which includes major responders and patients with stable disease, was 82%.
Exploratory analyses showed that 17 of 35 patients (49%) whose disease was estrogen receptor positive (ER+) had major responses. Median progression-free survival in the ER+ population was 7.3 months. In women with "triple-negative" disease, which is relatively insensitive to chemotherapy, 3 of 9 patients responded (33%).
Tesetaxel was generally well-tolerated. Neutropenia was the most common Grade 3-4 adverse event. The incidence of Grade 4 neutropenia was sharply reduced (from 32% to 11%) after dose escalation (from the starting level of 27 mg/m2 to 35 mg/m2) was discontinued -- a change that has now been incorporated into all protocols. Consistent with prior studies, no hypersensitivity reactions were observed.
"These data confirm results from our prior study, both of which show substantial activity for tesetaxel in patients with advanced, HER2-negative breast cancer", said Dr. Loretta M. Itri, Genta's President, Pharmaceutical Development, and Chief Medical Officer. "Genta is also exploring an alternate dosing schedule in this population using weekly treatment. Based on this favorable experience, and after conferring with regulatory authorities in the U.S. and EU, Genta plans to proceed with a new randomized trial of tesetaxel as initial, single-agent chemotherapy for patients with recurrent breast cancer."
About Tesetaxel
Taxanes (including paclitaxel and docetaxel) are the most widely used chemotherapy drug class in cancer medicine. However, these agents are associated with serious safety issues, particularly hypersensitivity reactions related to intravenous infusions that are occasionally fatal and that require careful premedication and observation. Other prominent side-effects of this drug class include myelosuppression (low blood counts) and peripheral neuropathy (disabling nerve damage).
Unlike standard taxanes that must be administered intravenously, tesetaxel is a capsule that is taken by mouth. Compared with the standard agents, clinical and preclinical data show that tesetaxel:
-- Is active in diseases that are resistant to standard taxanes
-- Is not associated with serious (occasionally fatal) hypersensitivity
reactions
-- Eliminates requirements for premedication (e.g., steroids,
antihistamines, etc.)
-- Reduces damage to peripheral nerves
-- Offers flexible and convenient dosing for patients
Thus, tesetaxel offers substantial opportunities to improve patient convenience, safety, and anticancer activity.
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 is developing tesetaxel, a novel, orally absorbed taxane that is in the same class of drugs as paclitaxel and docetaxel. As the leading oral taxane in clinical development, tesetaxel has been evaluated in a broad program of completed or ongoing Phase 2a/Phase 2b clinical trials. The Company has announced that gastric (stomach) cancer will be the lead indication for registration. Genta is exclusively marketing Ganite(R) (gallium nitrate injection) in the U.S, which is indicated for treatment of symptomatic patients with cancer-related hypercalcemia that is resistant to hydration. The Company has developed proprietary oral formulations of the active ingredient in Ganite(R) that are being evaluated as potential treatments for diseases associated with accelerated bone loss.
