20 DELCATH SYSTEMS, INC CIRSE 2016 Secondary Resectability of Ocular Melanoma Liver Metastases (OMLM) Following Percutaneous Hepatic Perfusion (PFP) by M. Zeile, et al. Asklepios Barmbek Clinic (Hamburg, Germany) • evaluated 7 patients with unresectable ocular melanoma liver metastases treated with CHEMOSAT • ORR after 1-2 treatments was 71.4%; PFS was 9.9 months, HPFS was 11.2 months • Median survival for the study has not yet been reached, but is higher than 16.9 months. • Two patients showed secondary resectability on imaging after completing two treatments and remain alive for over 26 months following resections • no adverse events of grade 3 or higher • Conclusions - CHEMOSAT is safe to use in these patients; significant downsizing of OM liver metastases can be achieved; “if these promising results were further validated it may lead to a new standard of therapy for the treatment of patients with OM liver metastases.” Percutaneous Isolated Hepatic Perfusion (Chemosaturation) In Patients With Primary Or Secondary Liver Tumours: Experience In 20 Patients, by S. Marquardt et al., of Hanover Medical School in Hanover, Germany • Retrospective analysis of 20 pts with advanced disease from primary or metastatic liver cancers • local response rate (stable disease or partial response) was 80% • Mean PFS was 3.2 months • Investigators reported no major complications and that bone marrow suppression was common but controllable • Conclusion - patients with primary or secondary liver tumors that have disease progression under standard therapy “may profit from PHP with Melphalan,” that technical execution is problem-free, and complications are manageable.

21 DELCATH SYSTEMS, INC 6 th European Post-Chicago 2016 Chemosaturation Via Percutaneous Hepatic Perfusion – An Update on A Single Centre Experience of Treating Metastatic Uveal Melanoma Southampton University (United Kingdom) Methods – A retrospective evaluation of 27 patients treated with CHEMOSAT over 4 years; analysis of survival, tumor response, time to progression and treatment related adverse events; 25 patients received 43 treatments, 24 were evaluable Results - 14 patients remained alive after median 290 days o 1 complete response (4%), 5 partial responses (21%), 12(50%) stable disease >90 days o Progression free survival for patients who had progressed was 181 days at the time of data cut off o 11/17 patients alive >1 year following their first treatment with projected OS of 511 o 11 deaths from disease progression occurred median 264 days following first treatment; no treatment related deaths Adverse Events (AEs) - treatment overall was well tolerated o Non-hematological AEs were rare (6) o Most common adverse events was transient, mild grade 2 transaminitis (64%) and thrombocytopenia (88%); grade 3 anemia seen in 36% of patients, grade 2-4 neutropenia was seen in 24% patients Conclusion – PHP achieves “unprecedented progression free and overall survival,” and can be used safely by an experienced multidisciplinary team to administer liver directed therapy in select UM patients.
