About Delcath Systems

•

A specialty pharmaceutical and medical device oncology company with a

principal therapeutic focus on the treatment of primary liver cancer and other

cancers that have metastasized to the liver

•

Proprietary system isolates the liver from circulation, delivers a substantially

higher concentration of chemotherapy (melphalan) compared with systemic

doses, and filters most of the chemotherapy out of the blood prior to returning

it to the patient

•

In late-stage clinical development in the U.S. with initial commercial activities

underway in Europe

•

Initially pursuing orphan indications in metastatic ocular melanoma, 

hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma

•

Cancers of the liver remain a major unmet medical need

o

Large

population

–

approximately

1.2

million*

patients

diagnosed annually with primary or metastatic liver cancer

o

The liver is often the life-limiting organ for cancer patients and one of the

leading causes of cancer death

o

Prognosis after liver involvement is poor, with overall survival generally

less than 12 months

•

7DELCATH SYSTEMS, INC

Concentrating the Power of Chemotherapy for Disease Control in the Liver

Our Solution:  Whole Organ-Focus Disease Control

•

Our proprietary system isolates the liver circulation, delivers a

high concentration of chemotherapy (melphalan) and filters

most of the chemotherapy out of the blood prior to returning it

to the patient

•

The procedure typically takes approximately 2-3 hours to

complete and involves a team including the interventional

radiologist and perfusionist

•

We believe more than 200 treatments with improved device

and procedure in the U.S. and EU provide confidence safety

can be validated in a controlled setting

Clinically Differentiated Results

•

Phase 1, 2 and 3 trials produced positive results in multiple histologies

•

Melanoma Liver Mets

o

Positive Phase 3

results in hepatic metastatic melanoma

o

n=93 (90% ocular melanoma, 10% cutaneous melanoma)

•

Neuroendocrine Tumor (NET) Liver Mets

o

mNET cohort in Phase 2

trial showed encouraging 42% objective response rate

(ORR) vs. ~10% for approved targeted therapy

o

Median overall survival of ~32 months on ITT basis

•

Hepatocellular Carcinoma (HCC)

o

Positive signal with high-dose melphalan in HCC cohort of Phase 2

trial (5/8 patients)

is encouraging when approved systemic therapies have modest efficacy and

challenges with tolerability

•

Colorectal Cancer (CRC) Liver Mets

o

Data from surgical Isolated Hepatic Perfusion (IHP) with melphalan indicates strong

potential in well-defined patient population with earlier stage CRC yielding ~50-60%

median response rate and median OS of 17.4-24.8 mos

•

Analysis of 20 patients who received 34 treatments at Southampton

University Hospital

o

Eleven patients remain alive after a median of 280 days with one complete

response ongoing at >1 year

o

From the diagnosis of liver metastases, 11 patients (55%) survived to one year and

3 (15%) for >2 years; no procedure related deaths were seen

o

2 patients (10%) demonstrated stable disease for >3 months, 13 patients (65%)

had a partial response, 2 patients (10%) demonstrated complete response

o

Nine deaths from disease progression occurred after a median of 264 days from

the first procedure

•

Adverse Events

o

Early AEs often expected with percutaneous hepatic perfusion (PHP) were

observed including coagulopathy, electrolyte disturbances and transient

transaminases (elevated liver enzymes).

Rare late AEs (1 patient each) included

hair loss, skin rash, myelosuppression

and persistent transaminases (elevated liver

enzymes)

o

AEs seen were grade 1 (n=12), 2 (n=13), 3 (n=5) and 4 (n=1)

o

Grade 4 complication was pulmonary edema due to fluid overload

23DELCATH SYSTEMS, INC

melanoma treated

with Melphalan/HDS (n=10), chemoembolization

(CE, n=12), and yttrium-90 (Y90,

o

Study showed significant difference in hepatic progression free survival (HPFS) for

Melphalan/HDS (310 days), CE (80 days), Y-90 (54 days)

o

Median overall survival (OS) longest for Melphalan/HDS (736 days) vs

Y90 (285
