Conference Call and Webcast Today at 4:30 p.m. ET -

QUEENSBURY, NY - May 8, 2013 - Delcath Systems, Inc. (NASDAQ: DCTH) today reported financial results and operational highlights for the fiscal first quarter ended March 31, 2013. Highlights for the quarter and recent weeks are as follows:

First Quarter Financial Results

For the three months ended March 31, 2013, Delcath recorded revenue of approximately $0.4 million, of which $0.3 million was related to the recognition of previously deferred revenue as a result of satisfying certain requirements of the Company's Research and Distribution agreement with Chi-Fu Trading Co. Ltd. in Taiwan. The remainder of the revenue was related to product sales. Operating loss was $10.2 million, which included approximately $0.7 million in non-cash stock-based compensation expense, as compared with an operating loss of $14.6 million, including $0.9 million in non-cash stock-based compensation expense, in the year ago period. Selling, general and administrative (SG&A) expenses in the first quarter of 2013 decreased to $6.1 million from $7.4 million for the same period in 2012. Research and development (R&D) expenses for the first quarter decreased to $4.5 million from $7.1 million for the same period in 2012. The decrease is primarily due to a significant reduction in expenses related to the Company's New Drug Application (NDA) submission to the FDA, as well as  the Company's overall cost management efforts.

Delcath raised approximately $20.9 million before related expenses through the Company's At-the-Market (ATM) equity offering program during the first quarter of 2013. In addition, the Company raised $9.0 million before related expenses through its Committed Equity Financing Facility (CEFF) program during the quarter. At March 31, 2013, cash and cash equivalents were $42.8 million, compared with $23.7 million at December 31, 2012. For the first quarter, cash utilization was $11.3 million, a 23 percent reduction compared to $14.7 million in the first quarter of 2012. The decrease in cash utilization was in part due to a reduction in NDA submission related costs and elimination of non-recurring one-time expenses related to the Company's initiating commercialization activities in Europe. The Company is implementing its previously announced program to reduce its quarterly cash burn to approximately $9-10 million in the second half of 2013, and is examining additional expense reduction strategies.

EU Commercialization Status

During the quarter, the Company continued commercialization of its Delcath Hepatic CHEMOSAT^® Delivery system for melphalan in the European Union.  The first center in the Netherlands was activated, with the first patients treated at the National Cancer Institute in Amsterdam. Revenue ramp was slower than anticipated as the Company continues to pursue permanent, compelling reimbursement for CHEMOSAT procedures in Europe.

 ODAC Outcome

On May 2, 2013, the Oncologic Drugs Advisory Committee (ODAC) to the US Food and Drug Administration voted 16 to 0 that the benefits of treatment with Melblez Kit do not outweigh the risks.  The Company is disappointed in the results of the ODAC vote and will continue to work with the FDA throughout its ongoing evaluation of the the Company's NDA for the Melblez Kit.  It should be noted that the ODAC vote was focused on data generated during the Phase 3 pivotal trial using the Generation One system.  The Company disagrees with the FDA characterization of the safety data during the conduct of the clinical trials on several important points:  FDA's views related to patient deaths due to treatment, effectiveness of the serious adverse event mitigation measures instituted in the protocol, and FDA's attribution of patient related deaths due to the filter. As a result of the ODAC outcome, the Company is currently evaluating strategies with regard to pursuing approval to market the Melblez Kit in the United States.

Clinical Development Program

During the quarter the Company held a productive discussion with the FDA on a trial design for a Phase 3 clinical trial in patients with hepatocellular carcinoma (HCC). Based on the positive efficacy signal seen during the Company's Phase 2 trial in HCC, and on the market potential in this tumor type, the Company is focusing its Clinical Development Program in this promising area. Subject to agreement with the FDA, the Company expects to begin enrolling patients in this global Phase 3 trial intended for U.S. registration by the end of 2013. The Company also continues to pursue data collection efforts inclusive of safety data via the U.S Expanded Access Program in metastatic melanoma.  Additionally, the Company has initiated a retrospective data collection trial and is initiating a prospective registry in the EU.
