Comparing treatment with the Delcath PHP System&#8482; with melphalan to Best Alternative Care (BAC), based on independent core lab review of patient scans, the statistical analysis revealed that the PHP patients had a statistically significant longer median hPFS of 214 days compared to 70 days in the BAC arm (p=0.001). This reflects a 144-day prolongation of hPFS over that of BAC control arm, with less than half the risk of progression and/or death in the PHP group compared to the BAC group (Hazard Ratio = 0.46). A copy of Delcath&#8217;s April 21, 2010 press release is included in Exhibit 99.1 to this Current Report on Form 8-K.</font></div>

Item 8.01 Other Events.
On April 21, 2010, Delcath Systems, Inc. issued a press release announcing that its Phase III National Cancer Institute (NCI)-led multi-center clinical trial has successfully met the study's primary endpoint of extended hepatic progression-free survival (hPFS) in patients with melanoma metastases to the liver based on an independently corroborated intent-to-treat analysis. Comparing treatment with the Delcath PHP System™ with melphalan to Best Alternative Care (BAC), based on independent core lab review of patient scans, the statistical analysis revealed that the PHP patients had a statistically significant longer median hPFS of 214 days compared to 70 days in the BAC arm (p=0.001). This reflects a 144-day prolongation of hPFS over that of BAC control arm, with less than half the risk of progression and/or death in the PHP group compared to the BAC group (Hazard Ratio = 0.46). A copy of Delcath's April 21, 2010 press release is included in Exhibit 99.1 to this Current Report on Form 8-K.
The Company will host a conference call today to discuss these results at 5:15 p.m. ET. Eamonn Hobbs, CEO, Dave McDonald, CFO, Dr. Kris Kandarpa, CMO, and Jason Rifkin, SVP of Clinical Affairs will host the call.
