Genta Incorporated Receives Special Protocol Assessment From FDA For Confirmatory Trial Of Genasense(R) Plus Chemotherapy In Chronic Lymphocytic Leukemia

BERKELEY HEIGHTS, N.J., July 26 /PRNewswire-FirstCall/ -- Genta Incorporated announced that the Company's proposal for a confirmatory trial of Genasense(R) (oblimersen sodium) Injection in patients with chronic lymphocytic leukemia (CLL) has completed Special Protocol Assessment (SPA) by the Food and Drug Administration (FDA). The SPA documents FDA's agreement regarding the trial's design and planned analyses to fulfill commitments that may be required under provisions related to SubPart H regulations regarding accelerated approval. Genta has filed a New Drug Application (NDA) under SubPart H for Genasense plus chemotherapy, which is currently under review by FDA. The NDA has a target action date for a marketing approval decision by October 29, 2006 under the Prescription Drug User Fee Act (PDUFA).

The trial, which will be conducted in symptomatic patients who have not previously received chemotherapy, will randomize patients to receive fludarabine plus rituximab (Rituxan(R); Genentech, Inc.) with or without Genasense. The pivotal trial in the pending NDA employed a combination of fludarabine plus cyclophosphamide with or without Genasense in patients with relapsed or refractory CLL.

"Data from our previous randomized trials have suggested that extensive prior treatment may introduce other mechanisms of acquired drug resistance," said Dr. Loretta M. Itri, Genta's Chief Medical Officer and President, Pharmaceutical Development. "This study targets treatment-naïve patients with a regimen that is still considered investigational, but which includes the most widely prescribed drugs for CLL in the U.S. With this trial, we reaffirm our commitment to patients with this illness, and we are very pleased with FDA's review of this next-step proposal."
