PRESS RELEASE: Delcath Voluntarily Defers Accrual in Clinical Trials

Delcath Voluntarily Defers Accrual in Clinical Trials

NEW YORK -- Oct 23, 2007 - Delcath Systems announced today that it received a letter late yesterday from the U.S. Food and Drug Administration (FDA) recommending that the Company temporarily suspend enrollment in the Phase III and Phase II trials of the Delcath System, and submit an analysis of adverse events in anticipation of a meeting with the Agency to discuss certain gastrointestinal (GI) safety concerns. The recommendation was issued by the Agency following reports of GI events submitted by the Company to the FDA that may have been related to the infusion of melphalan. Delcath plans to submit to the FDA its analysis of these adverse events and their relation to the Delcath System within the next fifteen days.

Delcath had previously reported four serious adverse events, two of which resulted in deaths, to the FDA and the National Cancer Institute (NCI) Institutional Review Board (IRB) as well as to the Data Safety Monitoring Board (DSMB) for the Phase III trial. Delcath worked with the Principal Investigator to amend the protocols to prevent future adverse events and those changes were approved by the NCI IRB and implemented into the trials. 

Delcath plans to meet with the FDA to address the issues raised by the Agency and to present changes that have already been made to the trial protocols that the Company believes will remedy the Agency's safety concerns. In addition, Delcath will present the Agency with current data from the clinical trials that will allow for the analysis of the clinical benefits of the Delcath System. It is hoped that the FDA will agree that the changes that have already been implemented in the protocol will mitigate, and possibly eliminate, the incidence of these GI events. Until then, the Company will voluntarily defer accrual of new patients in the Phase III and Phase II trials. The Company anticipates that patients currently enrolled in the trials will continue to receive their treatments under the approved protocols.

Richard L. Taney, President and Chief Executive Officer of Delcath, commented, "We are prepared to meet with the FDA as soon as possible, and will present a thorough analysis of these GI episodes. We will update our investors promptly on resolution of this issue."
