ITEM 1.01. ENTRY INTO A MATERIAL DEFINITIVE AGREEMENT On March 29, 2007, Delcath Systems, Inc. (the "Company") announced that it entered into a five-year extension of its Cooperative Research and Development Agreement (the "CRADA") with the National Cancer Institute ("NCI"), which enhances and expands the initial agreement between the Company and NCI that expired in December 2006. Under the revised CRADA, the Company and NCI agreed that the parties will collaborate in the joint development and evaluation of the Delcath System device to deliver high-dose Melphalan to patients and to evaluate the advisability of developing additional commercial agents for use with the Delcath System, the Company's percutaneous perfusion technology for region-specific delivery of chemotherapeutic and other therapeutic agents. The revised CRADA also established that NCI's Surgery Branch will work towards completion of Delcath System's ongoing Phase III trial and will serve as the coordinating center when this study expands to a multi-center trial. The Phase III trial is treating patients with melanoma (ocular or cutaneous) metastatic to the liver using the Delcath System and the drug Melphalan. ITEM 9.01.

          DELCATH SYSTEMS EXTENDS COOPERATIVE RESEARCH AND DEVELOPMENT
                  AGREEMENT WITH THE NATIONAL CANCER INSTITUTE

    5-YEAR AGREEMENT PROVIDES FOR EXPANDED DEVELOPMENT OF DELCATH'S REGIONAL
                                 CANCER THERAPY

STAMFORD, CT, MARCH 29, 2007-Delcath Systems, Inc. (Nasdaq: DCTH) today
announced that the Company has signed a five year extension to its Cooperative
Research and Development Agreement ("CRADA") with the National Cancer Institute
("NCI"). This extension enhances and expands the initial CRADA that expired in
December 2006. The new five year extension provides for the Company and the NCI
to collaborate in the joint development and evaluation of the Delcath Systems
device to deliver high-dose Melphalan to patients, and to evaluate the
advisability of developing additional commercial agents for use with the Delcath
System, the Company's percutaneous perfusion technology for region-specific
delivery of chemotherapeutic and other therapeutic agents.

Under the new agreement, the Surgery Branch of the NCI will work towards
completion of Delcath System's pivotal ongoing Phase III trial for patients with
metastatic melanoma in the liver using the drug Melphalan, and is expected to
serve as the coordinating center when this study expands to a multi-center
trial. The Phase III study is treating patients with ocular and cutaneous
melanoma who have unresectable tumors in the liver, using the Delcath System to
deliver the drug. The Delcath System is designed to isolate the patient's liver
in order to allow significantly higher dosing of Melphalan while limiting the
systemic toxicities that result from current intravenous chemotherapy
treatments.

Patients in the Phase III trial are randomly assigned to one of two initial
treatment arms, for immediate treatment with Melphalan via the Delcath System,
or alternatively, treatment with best alternative care. The study is designed to
evaluate the duration of tumor response in each of the two arms of the study.
Following the guidelines established by the FDA for this trial under a Special
Protocol Assessment, when the disease progresses (tumor grows) in patients
receiving best alternative care, they are allowed to "cross over" and receive
treatment with the Delcath System. The FDA has approved expansion of the trial
to include up to 15 centers. Upon appropriate NCI Institutional Review Board
("IRB") approval (currently pending), this trial will be expanded to a
multi-center trial.

The NCI will continue conducting the Phase II clinical study of Melphalan in
patients with primary and metastatic hepatic malignancies using the Delcath
System. One of the arms of this multi-histology study was recently expanded to
include twenty-five patients after showing tumor response in 75% of the patients
treated to date. These results generated significant interest among cancer
researchers when they were presented at a recent international cancer symposium
this past February. The NCI will also conduct pharmacokinetic analyses of
patient samples in the Phase II and Phase III clinical trials to characterize
the pharmacokinetic advantage of Melphalan delivered to the liver using the
Delcath System, will provide and perform primary database management and
statistical analysis for the Melphalan trials, and will conduct ongoing
hematological biocompatibility and extraction testing of Melphalan in human
plasma and whole blood.

In addition, the NCI may perform preclinical animal and filter testing to
provide the basis for supporting Phase I trials for additional
chemotherapeutics. Investigating different chemotherapeutics such as
Oxaliplatin, along with development of additional protocols utilizing the
Delcath System for the isolated treatment of cancers in other body regions (such
as colorectal, limb and pancreatic), may be conducted by mutual agreement of
Delcath and the NCI.

Richard L. Taney, Chief Executive Officer of Delcath Systems, commented on the
agreement, "We are very pleased to have reached an expanded CRADA with the NCI.
This is a significant milestone for Delcath as it allows us to continue our
collaboration with the world's premier oncology researchers and clinicians in
order to advance the clinical development of the Delcath System, thereby
bringing regional cancer therapy to patients with limited treatment options.
Importantly, it provides for the expected expansion of the current Phase III
trial into a multi-center trial, which should accelerate patient recruitment and
propel the Delcath System toward commercialization."

"The breadth of this five-year agreement underscores the potential for our organ
or region-specific delivery of therapeutic agents to better treat cancer
patients. This enhanced collaboration allows for the potential expansion of our
platform perfusion technology to other approved chemotherapeutics via the
Delcath System, a goal which remains a primary strategic objective of our
company" concluded Mr. Taney.
