Release Details

NEW YORK, Nov. 13, 2023 /PRNewswire/ -- Delcath Systems, Inc. (Nasdaq: DCTH) ("Delcath" or the "Company"), an interventional oncology company focused on the treatment of primary and metastatic cancers of the liver, today reported business highlights and financial results for the third quarter ended September 30, 2023.

Recent Business Highlights

• Received approval from the US Food and Drug Administration (FDA) for HEPZATO KIT™ (melphalan)/Hepatic Delivery System) as a liver-directed treatment for adult patients with metastatic uveal melanoma (mUM) with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease, or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation;
• Raised approximately $35 million through the exercise of all the Tranche A warrants issued as part the previously announced March 29, 2023, financing with up to an additional $25 million available upon the achievement of $10 million in quarterly revenue;
• Announced publication by independent investigators of a retrospective comparative study of CHEMOSAT^® Hepatic Delivery System for Melphalan percutaneous hepatic perfusion (PHP) and Selective Internal Radiation Therapy (SIRT) citing a statistically significant difference in median overall survival with 301 days for SIRT and 516 days for PHP;
• Announced that independent investigators at Leiden University recruited 55 of 76 planned patients in the CHOPIN trial studying the impact of CHEMOSAT and immune checkpoint inhibitor combination therapy in the treatment of metastatic uveal melanoma and expect the trial to be fully enrolled mid-2024. An interim futility analysis conducted in September resulted in the independent data monitoring committee recommending continuing the study without modification; and
• Partnered with seven clinical treatment sites to satisfy the initial training requirements to be able to treat their first commercial patient, subject to proctor availability and the sites' value analysis committee approvals, upon the planned launch in January.

"The Company has been preparing for a January launch of HEPZATO KIT by building our commercial team and engaging with potential treating centers," said Gerard Michel, Chief Executive Officer of Delcath. Mr. Michel added, "We have been encouraged by the reception that HEPZATO KIT has received from the medical oncologist community and are confident that by the end of 2024 at least 15 centers will be actively treating metastatic uveal melanoma patients with HEPZATO KIT."

Third Quarter 2023 Results

Total revenue for the three months ended September 30, 2023, was approximately $0.4 million, compared to $0.9 million for the prior year period, from our sales of CHEMOSAT in Europe.

Research and development expenses for the quarter were $4.7 million, compared to $4.1 million in the prior year quarter. The increase in R&D expense is primarily due to completing clinical trial activities and expenses related to the FDA inspection and other requests in advance of the approval received for HEPZATO.

Selling, general and administrative expenses for the quarter increased to $6.2 million, compared to $4.8 million in the prior year quarter primarily relating to activities to prepare for a commercial launch. The increase in fair value warrant liability adjustment during the quarter ended September 20, 20223 was a result of our final valuation for the Tranche A warrants exercised and outstanding Tranche B warrants.

About Delcath Systems, Inc., CHEMOSAT and HEPZATO KIT

Delcath Systems, Inc. is an interventional oncology company focused on the treatment of primary and metastatic liver cancers. The company's proprietary products, HEPZATO KIT (Hepzato (melphalan) for Injection/Hepatic Delivery System) and CHEMOSAT^® Hepatic Delivery System for Melphalan percutaneous hepatic perfusion (PHP) are designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects during a PHP procedure.

In the United States, HEPZATO KIT is considered a combination drug and device product and is regulated and approved for sale as a drug by the FDA. HEPZATO KIT is comprised of the chemotherapeutic drug melphalan and Delcath's proprietary Hepatic Delivery System (HDS). The HDS is used to surgically isolate the liver while simultaneously filtrating hepatic venous blood during melphalan infusion and washout. The use of the HDS results in loco-regional delivery of a relatively high melphalan dose, which can potentially induce a clinically meaningful tumor response with minimal hepatotoxicity and reduce systemic exposure. HEPZATO KIT is approved in the United States as a liver-directed treatment for adult patients with metastatic uveal melanoma (mUM) with unresectable hepatic metastases affecting less than 50% of the liver and no extrahepatic disease, or extrahepatic disease limited to the bone, lymph nodes, subcutaneous tissues, or lung that is amenable to resection or radiation. Please see the full Prescribing Information, including BOXED WARNING for the HEPZATO KIT.

In Europe, the device-only configuration of the HDS is regulated as a Class III medical device and is approved for sale under the trade name CHEMOSAT Hepatic Delivery System for Melphalan, or CHEMOSAT, where it has been used in the conduct of percutaneous hepatic perfusion procedures at major medical centers to treat a wide range of cancers of the liver.
