Delcath Expands Multi-Center Phase III Trial for Metastatic Melanoma

NEW YORK, NY--(Marketwire - June 24, 2008) - Delcath Systems, Inc. (NASDAQ: DCTH) announced today that the University of Texas Medical Branch at Galveston (UTMB), part of the University of Texas System, has joined Delcath's Phase III clinical trial for the treatment of inoperable metastatic melanoma in the liver using the Company's Percutaneous Hepatic Perfusion (PHP) System for the isolated, high-dose delivery of the anti-cancer agent melphalan. UTMB is the sixth center in this multi-center study testing the Delcath System.

Delcath and UTMB have entered into a clinical research agreement to conduct the Phase III National Cancer Institute (NCI) led study. Orhan S. Ozkan, MD, Associate Professor of Radiology and Director of Vascular and Interventional Radiology, will serve as the Principal Investigator of the study. On joining this study, Dr. Ozkan commented, "We are excited about being a part of this clinical trial and being the first center to offer this treatment modality to patients in this region of the US. This treatment offers tremendous promise for patients suffering from metastatic melanoma in the liver, and we are pleased to be able to offer this option to our patients."

Over the past two months, Delcath Systems has added five cancer centers to this Phase III trial, which needs fewer than sixty additional patients to reach full enrollment. On the addition of UTMB to this study, Richard Taney, President and CEO of Delcath, stated, "We continue our efforts to make this treatment option available at leading cancer centers throughout the United States. Dr. Ozkan's participation will provide patients in the southwest region of the country access to this trial and provides an important treatment option for inoperable metastatic melanoma to the liver. The interest in PHP by the physicians treating this fatal condition continues to grow and we continue working to expand the geographic availability of our technology."

The Phase III Study

The Phase III study is designed to test Delcath's proprietary PHP 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 is designed to deliver significantly higher doses of anti-cancer drugs to a patient's liver while preventing entry of the drugs to the rest of the patient's circulation. This isolation limits toxicities that result from 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 U.S. Food and Drug Administration (FDA) under a Special Protocol Assessment (SPA), 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 III study, which recently exceeded 33% enrollment, is expected to be completed in 2009, leading to an application to the US Food and Drug Administration (FDA) for commercial approval of the PHP System.
