Delcath Resumes Enrollment in Phase III and Phase II Trials

NEW YORK--(HSMN NewsFeed)--Delcath Systems, Inc. (NASDAQ:DCTH ) announces that the U.S. Food and Drug Administration (FDA) has notified the Company that patient enrollment may resume in the Phase III and Phase II clinical trials of the Delcath System. Current and prospective clinical investigation sites have been notified that study accrual can be resumed immediately. This decision follows Delcath’s meeting with representatives of the U.S. Food and Drug Administration (FDA), along with the Principal Investigator at the National Cancer Institute (NCI).

Resumption of study accrual follows a voluntary enrollment deferral announced by the Company on October 23, 2007 in response to an FDA inquiry into certain gastrointestinal adverse events observed in four patients enrolled in the studies of the Delcath System prior to protocol changes enacted earlier this year. During the meeting at the FDA, which was attended by senior reviewers from both the Drug and Device arms of the Agency, the Principal Investigator presented an analysis of the previously reported gastrointestinal toxicities and of the changes incorporated into the trial protocols to prevent a recurrence of (GI) toxicities. These changes had been previously approved by the NCI Institutional Review Board (IRB) and were subsequently approved by the Data Safety Monitoring Board (DSMB) for the Phase III trial. The Company has been notified in writing by the FDA that the studies can proceed with the amended protocol.

“We are pleased with the Agency’s prompt response to and resolution of this issue. We are very appreciative of the timely assistance of the NCI which allowed us to respond to the Agency less than a week after receiving the letter and their presentation of the data contributed greatly to the unusually quick resolution of this matter. A thorough analysis of the clinical facts surrounding these episodes combined with the clinical benefits demonstrated by the Delcath System for these extremely ill patients allowed for a balanced evaluation of FDA safety concerns,” said Richard L. Taney, President and Chief Executive Officer of Delcath Systems.

“We look forward to recruiting additional oncology centers for the expansion of our clinical trials as we believe that use of the Delcath System for the targeted, region-specific delivery of high-dose chemotherapeutic agents can bring significant clinical benefit to late-stage cancer patients with very limited treatment options, and consequently, poor prognoses, ” concluded Mr. Taney.

The Phase III Trial

The Phase III study, now resuming enrollment at the NCI, is testing the Delcath System for the regional delivery of melphalan to the liver to treat patients with metastatic ocular and cutaneous melanoma who have unresectable tumors in the liver. The Delcath System isolates the blood flow within the patient’s liver in order to allow significantly higher doses of the anti-cancer drug to be administered while limiting the toxicities that result from current systemic chemotherapy treatments.

Patients in the Phase III trial initially are randomized into one of two treatment arms, including immediate treatment with melphalan via the Delcath System or treatment with best alternative care. The study is designed to evaluate the duration of tumor response in each of the two study arms. Following guidelines established by FDA under a Special Protocol Assessment, when disease progresses in patients enrolled in the best alternative care arm of the trial, they are permitted to “cross over” and receive treatment with the Delcath System.

The Phase II Trial

The Phase II clinical trial, also resuming enrollment at the NCI, is testing use of the Delcath System for the organ-specific delivery of the chemotherapeutic agent melphalan in patients with specific tumors in the liver, including primary liver cancer, metastatic neuroendocrine tumors, adenocarcinomas in the liver, and metastatic melanoma in the liver of patients who previously received isolated hepatic perfusion, but whose cancer has since returned.
