NEW YORK, May 21, 2015 /PRNewswire/ -- Delcath Systems, Inc. (NASDAQ: DCTH) announces that the intrahepatic cholangiocarcinoma (ICC) study cohort of its expanded Global Phase 2 Clinical Trial Program of Melphalan/HDS for use in the treatment of patients with unresectable hepatocellular carcinoma (primary liver cancer, or HCC) has opened for patient enrollment. The ICC study will be conducted at the same hospitals in Europe participating in the Company's Phase 2 HCC trial, and ICC enrollment is now open at Goethe University Hospital in Frankfurt, the Medical School Hannover and Jena University Hospital. Additional centers in Germany as well as centers in the United Kingdom are expected to open for enrollment in the coming weeks.
ICC is a tumor in the bile duct that arises within the liver. It is the second most common primary liver tumor and represents approximately 15% of new HCC cases diagnosed annually. Surgical resection, the standard of care, is not possible for an estimated 80% to 90% of patients diagnosed with ICC.
The ICC cohort of the Phase 2 trial will investigate the safety and efficacy of Melphalan/HDS treatment in patients with unresectable ICC confined to the liver. This cohort will evaluate tumor response (objective response rate) as measured by modified Response Evaluation Criteria in Solid Tumor (mRECIST), and will assess progression-free survival and safety. Additional analyses will be conducted to characterize the systemic exposure of melphalan administered by Melphalan/HDS, as well as to assess patient-reported clinical outcomes, or quality-of-life.
"We believe our Melphalan/HDS treatment may offer significant clinical benefit for ICC patients who face limited treatment options," said Jennifer Simpson, Ph.D., Interim President and CEO of Delcath Systems. "A positive efficacy signal may provide a regulatory pathway to a U.S. registration trial, and consolidated safety data from the HCC and ICC cohorts of this global Phase 2 trial will offer valuable information for us to provide to the FDA."
About Delcath Systems Delcath Systems, Inc. is a specialty pharmaceutical and medical device company focused on oncology with a principal focus 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. Melphalan/HDS is considered a combination drug and device product, and is regulated as a drug by the U.S. Food and Drug Administration (FDA). Melphalan/HDS 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 Melphalan/HDS for the treatment of primary liver cancer (hepatocellular carcinoma or HCC), and we are initiating a cohort within the global phase 2 clinical trial to evaluate patients with intrahepatic cholangiocarcinoma (ICC). We are also advancing plans to conduct a global Phase 3 trial in ocular melanoma that has metastasized to the liver.
