3 DELCATH SYSTEMS, INC Our Mission Concentrating the Power of Chemotherapy for Disease Control in the Liver We are a cancer therapy company Our technology offers the opportunity to gain control of tumors in the liver The liver is a site where uncontrolled disease is often life-limiting or leads to withdrawal of systemic treatments in favor of palliative care We plan on being a fully-integrated company and are building the infrastructure to develop and commercialize our products in Europe and North America o In Europe our first product is approved and we have begun selling it We believe that our first product, CHEMOSAT, may extend the lives of a large number of cancer patients

4 DELCATH SYSTEMS, INC Existing Liver Cancer Treatments Have Significant Limitations The Problem • Metastatic disease to the liver, brain or lungs is often the life- limiting location of solid tumors o In contrast to the brain and lungs, where systemic chemotherapy and radiation can exert some degree of local control, tumors in the liver are not particularly responsive to chemotherapy and radiation therapy • Existing treatments to control tumors in the liver include: Surgical resection Radioembolization (SIRT) Chemoembolization (TACE) Radiofrequency ablation (RFA), Microwave, Cryoablation Hepatic arterial infusion (HAI) Systemic chemotherapy

5 DELCATH SYSTEMS, INC Existing Liver Cancer Treatments Have Limitations Unmet Medical Need Exists for More Effective Liver Cancer Treatments Treatment Advantages Disadvantages Systemic – Non-invasive – Repeatable – Systemic toxicities – Limited efficacy in liver Regional (e.g., Isolated Hepatic Perfusion) – Therapeutic effect – Targeted – Invasive/limited repeatability – Multiple treatments are required but not possible Focal (e.g. surgery, radioembolization, chemoembolization, radio frequency ablation) – Partial removal or treatment of tumors – Only 10% to 20% resectable – Invasive and/or limited repeatability – Treatment is limited by tumor size, number of lesions and location – “See a tumor, treat a tumor”

6 DELCATH SYSTEMS, INC Concentrating the Power of Chemotherapy for Disease Control in the Liver Our Solution • Our proprietary CHEMOSAT system isolates the liver circulation, delivers an ultra-high concentration of chemotherapy (melphalan) to the liver and filters most of the chemotherapy out of the blood prior to returning it to the patient • The procedure typically takes approximately two hours to complete and involves a team including the interventional radiologist and perfusionist • CHEMOSAT (Gen 2) has demonstrated minimal systemic toxicities and impact to blood components in initial commercial use and may complement systemic therapy • CHEMOSAT has been used on approximately 200 patients to date through clinical development and early commercial launch

7 DELCATH SYSTEMS, INC Chemosaturation 1. ISOLATE 2. SATURATE 3. FILTRATE The Delcath CHEMOSAT System Improved disease control in the liver Treats entire liver (macro and micro) Controls systemic toxicities Allows for over 100x effective dose escalation at tumor site Repeatable & minimally invasive, Complements systemic therapy Minimally Invasive, Repeatable Liver Procedure That Could Complement Systemic Therapy Note: Image not to scale.

8 DELCATH SYSTEMS, INC Concentrating the Power of Chemotherapy for Disease Control in the Liver The Data • We conducted a randomized Phase 3 study under a Special Protocol Assessment (“SPA”) using Generation 1 of our chemosaturation system in patients with melanoma (ocular and cutaneous) metastatic to the liver • Melanoma liver metastases are relatively homogeneous regardless of origin • Liver metastases are typically the life-limiting aspect of the disease • Melanoma is notoriously insensitive to systemic chemotherapy and our study was a great demonstration of our technology’s potential in a challenging histology

9 DELCATH SYSTEMS, INC Phase III Clinical Trial Design Randomized to CS 92 patients: ocular or cutaneous melanoma Best Alternative Care (BAC) Investigator and patient decision (any and all treatments) CS/Melphalan Treat every 4 weeks x 4 rounds (responders can receive up to 6 rounds) Cross-over Primary Trial Endpoint • Statistically significant difference in Hepatic Progression Free Survival (“hPFS”): p < 0.05 (IRC) • Over 80% of Oncologic drugs approved by FDA between 2005 – 2007 on endpoints other than overall survival Modeled hPFS for Trial Success: 7.73 months (CS) vs. 4 months (BAC) Secondary Trial Endpoints • Investigator hPFS • Hepatic response and duration of hepatic response • Overall response and duration of overall response • Overall Survival – Diluted by Cross Over • SAP calls for analysis of various patient cohorts Pre-CS (Baseline) Post-CS (22+ Months) Hepatic Response – Metastatic Melanoma Fully Powered, 93 Patient, Randomized, Multi-Center NCI Led Study CS = ChemoSaturation (CHEMOSAT)
