First of Several Abstracts on CHEMOSAT to be Presented at Major Medical Meetings in Autumn 2015

NEW YORK, Sept. 28, 2015 /PRNewswire/ -- Delcath Systems, Inc. (NASDAQ: DCTH), a specialty pharmaceutical and medical device company focused on oncology with an emphasis on the treatment of primary and metastatic liver cancers, announces that data from two EU treatment centers supporting treatment of patients with liver metastases from ocular melanoma with the Delcath Hepatic CHEMOSAT® Delivery System  (CHEMOSAT) will be presented as a poster at the European Cancer Congress (ECCO) annual meeting, being held in Vienna, Austria from September 25-29, 2015.

The study entitled, "Treating Unresectable Liver Metastases of Uveal Melanoma with (Percutaneous) Isolated Hepatic Perfusion with Melphalan: Results from Two Experienced Centers," by E.M. De Leede, M.C. Burgmans, et al., was a retrospective study conducted by investigators at Leiden University Medical Center (LUMC) and Erasmus Medical Center (EMC) in the Netherlands. Investigators compared patients with uveal (ocular) melanoma liver metastases treated with isolated hepatic perfusion (IHP), an open surgical procedure that can be performed only once, with patients treated with repeatable percutaneous hepatic perfusion  (PHP) using the CHEMOSAT system with an aim to treat patients twice with a six week interval. Treatment characteristics, complications, toxicity, progression free and overall survival of both therapeutic approaches were analyzed. Both IHP and PHP treatments were performed with melphalan.

In the IHP cohort (30 patients treated between March 1999 and April 2009) progression free survival was 6 months and recurrence was mainly in the liver, and overall survival was 10 months. In the PHP cohort (9 patients who received 15 PHP treatments since February 2014), the maximum follow-up period was 14 months. Eight patients are still alive, seven without progression of disease. A decrease in red and white blood cell count and thrombocytes after the procedure was observed, and 3 patients needed blood transfusions or platelet infusion. Treatment was overall well tolerated. Investigators concluded that "percutaneous hepatic perfusion appears to be an effective and safe procedure in selected patients with unresectable liver metastases of colorectal cancer or uveal melanoma and can be repeated."

"With eight out of nine patients still alive at 14 months in this retrospective analysis, this is an encouraging signal for PHP and we look forward to seeing the final data," said Jennifer Simpson, Ph.D., MSN, CRNP, President and CEO of Delcath Systems. "This study is the first of several scheduled posters on the clinical merits of CHEMOSAT to be presented at major medical meetings this fall. We expect this growing body of clinical data will advance the continued adoption of CHEMOSAT in Europe and will support our ongoing reimbursement efforts in those territories."

The abstract of this study is available on the ECCO 2015 website.

About Delcath Systems

Delcath Systems, Inc. is a specialty pharmaceutical and medical device company focused on oncology with an emphasis on the treatment of primary and metastatic liver cancers. Our proprietary Melphalan Hydrochloride for Injection for use with the Delcath Hepatic Delivery System (Melphalan/HDS) is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure. In April 2012 we obtained authorization to affix a CE Mark to our second-generation system, which is currently marketed in Europe as a device under the trade name Delcath Hepatic CHEMOSAT® Delivery System for Melphalan (CHEMOSAT). In the U.S. the Melphalan/HDS system is considered a combination drug and device product, and is regulated as a drug by the U.S. Food and Drug Administration (FDA). The Melphalan/HDS system has not been approved for sale in the U.S. We have commenced a global Phase 2 clinical trial in Europe and the U.S. to investigate the Melphalan/HDS system for the treatment of primary liver cancer (HCC) and intrahepatic cholangiocarcinoma (ICC), and expect to initiate a global Phase 3 trial in ocular melanoma (OM) that has metastasized to the liver.
