NEW YORK, Aug. 22, 2011 /PRNewswire/ -- Delcath Systems, Inc. (NASDAQ: DCTH) reported encouraging top-line results from the hepatobiliary cohort of the Phase II clinical trial of the Delcath chemosaturation system with melphalan in the treatment of patients with unresectable liver cancer. This study, conducted at the National Cancer Institute (USA), included four patient cohorts: hepatobiliary cancers, and metastatic cancers of neuroendocrine, ocular or cutaneous melanoma, and colorectal (adenocarcinoma) origins.
There were nine patients with tumors of hepatobiliary origin: five hepatocellular carcinomas (HCC) and four cholangiocarcinomas. HCC is the most common primary cancer of the liver, with approximately 500,000 new cases diagnosed worldwide annually. Both groups had positive efficacy signals. The responses were especially encouraging in the HCC cohort and consisted of confirmed partial response or durable stable disease. The safety profile of the chemosaturation system was consistent with that previously reported for the Company's Phase 3 melanoma trial.
"The disease control and anti-tumor activity seen in the HCC arm of this Phase II study is very encouraging for primary liver cancer patients who currently face limited treatment options," said Eamonn P. Hobbs, President and CEO of Delcath System, Inc. "We believe these results show a strong signal of efficacy, and support our plan to initiate Phase III and Phase IV trials for HCC in the second half of 2012."
Mr. Hobbs added, "We expect to announce additional data from this Phase II trial in the near future, and look forward to presenting detailed results from the metastatic neuroendocrine arm of this trial at the Cardiovascular and Interventional Radiological Society of Europe and European Society for Medical Oncology scientific meetings in September."
The trial's primary objectives were to determine the response rate and duration of response to intrahepatic infusion of melphalan with subsequent venous hemofiltration. Secondary objective measures included patterns of recurrence, progression-free survival and overall survival. Additional secondary objectives were to evaluate safety and tolerability in this patient population, and assess filter characteristics including melphalan pharmacokinetics and filtration of cytokines and clotting factors.
About Hepatocellular CarcinomasHepatocellular carcinoma (HCC) is a primary cancer of the liver and one of the most deadly forms of cancer. HCC ranks as the fifth most common solid tumor cancer, with an annual incidence of approximately 20,000 cases per year in the United States, approximately 40,000 cases per year in Europe and approximately 500,000 cases per year worldwide, due to the high prevalence of Hepatitis B and C in developing countries. Usually seen in people aged 50 – 60, this type of cancer occurs more often in men than women. Treatment options of HCC and prognosis are dependent on many factors including tumor size and location, the underlying functional capacity of the liver, and the stage of the disease. High-grade tumors will have a poor prognosis, while low-grade tumors may go unnoticed for many years. Hepatocellular carcinoma is potentially curable by surgical resection, but surgery is the treatment of choice for only the small fraction of patients with localized disease. The usual outcome is poor, because only 10-20% of HCC can be removed completely using surgery. If the cancer cannot be completely removed, the disease is usually deadly within 6 months.
About Delcath SystemsDelcath Systems, Inc. is a development stage specialty pharmaceutical and medical device company focused on oncology. Delcath's proprietary system for chemosaturation is designed to administer high dose chemotherapy and other therapeutic agents to diseased organs or regions of the body, while controlling the systemic exposure of those agents. The Company's initial focus is on the treatment of primary and metastatic liver cancers. In 2010, Delcath concluded a Phase III metastatic melanoma study, and the Company recently completed a multi-arm Phase II trial to treat other liver cancers. The Company obtained authorization to affix a CE Mark for the Hepatic CHEMOSAT delivery system in April 2011. The Company has not yet received FDA approval for commercial sale of its system in the United States. For more information, please visit the Company's website at http://www.delcath.com/.
