Phase 2 Results of Genasense(R) Plus Chemotherapy in Advanced Prostate Cancer Reported at Cancer Conference

BERKELEY HEIGHTS, N.J., Feb. 23 (HSMN NewsFeed) -- Genta Incorporated (Nasdaq: GNTA ) announced preliminary results from a Phase 2 study of Genasense® (oblimersen sodium) Injection plus chemotherapy in patients with advanced prostate cancer. This randomized open-label trial was conducted by the European Organisation for Research and Treatment of Cancer (EORTC). Dr. Cora N. Sternberg, from the San Camillo Forlanini Hospital in Rome, Italy, presented the data this afternoon at The Prostate Cancer Symposium, a joint meeting of the American Society of Clinical Oncology, the Society of Urologic Oncology and the American Society for Therapeutic Radiology and Oncology, which is being held this week in Orlando, Florida.

Of 111 patients who were evaluable in this study, 24% had previously received estramustine (a combination of estrogen plus a chemotherapy agent), 26% had pretreatment elevation of serum lactate dehydrogenase (LDH), and 41% had previously progressed in each of three clinical parameters including prostate specific antigen (PSA), bone, and viscera. At baseline, more than 90% of patients had widely metastatic disease to bone and/or viscera. Following randomization, patients were treated with docetaxel (Taxotere®; sanofi aventis) either with (N= 54) or without Genasense (N=57).

For patients who received Genasense plus docetaxel versus docetaxel alone, there were similar response rates as measured by RECIST criteria in patients with measurable disease (24% vs. 19%) or by PSA (37% vs. 46%). Neither progression-free nor overall survival has yet been reported. Occurrence of Grade 3-4 neutropenia (80% vs. 83%) and febrile neutropenia (11% vs. 9%) was similar, whereas Genasense was associated with an increase in Grade 3 thrombocytopenia (9% vs. 0%).

"A patient population with metastases to bone and viscera, elevated LDH, and prior chemotherapy may not have been ideally suited for study", noted Dr. Sternberg. "Data that support the activity of Genasense in earlier-stage disease were not known when this study was designed, and this information probably would have substantially impacted its design. Further study with Genasense may be warranted in patients with hormone-refractory prostate cancer whose disease is limited to a rising PSA."
