Low Side Effects Seen in Treatment With Delcath Systems, Inc.'s Second Generation Hemofiltration Cartridge

NEW YORK, April 26, 2012 /PRNewswire/ -- Delcath Systems, Inc. (NASDAQ: DCTH) announced today that doctors from the European Institute of Oncology (Instituto Europeo di Oncologia IEO) presented preliminary data showing reduced side effects in the first treatment using the Company's second generation Hepatic CHEMOSAT® Delivery System as compared to a prior treatment with the first generation system.

The comparison was presented at a sponsored symposium entitled Chemosaturation Therapy Initial European Experiences hosted by Delcath at the Third European Conference on Interventional Oncology (ECIO, April 25-28) heldin Florence, Italy. The session was moderated by Dr. Ricardo Lencioni, Director of Imaging and Diagnostic Intervention at the University of Pisa, and featured presentations by Dr. Pier Francesco Ferrucci, Director of Translational Research on Melanoma and medical oncologist at the IEO, Dr. Franco Orsi, Director of Interventional Radiology at the IEO, and Dr. Thomas J. Vogl, Director of the Institute of Diagnostic and Interventional Radiology at the J.W. Goethe University Hospital in Frankfurt, Germany.

Dr. Ferrucci presented the comparison of side-effect profiles in two CHEMOSAT treatments performed in a single patient. Treatment with the second-generation CHEMOSAT system showed brief mild bone marrow suppression and no significant related toxicities. In the prior treatment of the same patient, which was conducted with the first generation CHEMOSAT system, moderate to severe bone marrow suppression and related toxicities were noted.

"Though we are just beginning to explore the potential of the CHEMOSAT system, we are very encouraged by our initial experiences," said Dr. Ferrucci. "If the side-effect profile seen in our first case with the second generation system can be consistently repeated in subsequent treatments, it would suggest that the second generation CHEMOSAT is a real step forward in the development of this important therapeutic approach for cancers in the liver."

"We believe that data from this initial case validates the confidence we have in our Gen Two CHEMOSAT system as a result of our in vivo testing," said Eamonn P. Hobbs, President and CEO of Delcath Systems. "We are encouraged by the initial results and although this is only the first case, we're now even more confident that Gen Two will deliver the melphalan removal efficiency shown in our research, resulting in the improved side-effect profile demonstrated in this initial case. As more centers in Europe become familiar with the CHEMOSAT system's potential, we believe it will be adopted as an important new element in the treatment of patients with cancers in the liver."
