If You Invested in Delcath Sys (DCTH)

Delcath Systems Inc (Nasdaq: DCTH) is an interventional oncology company focused on the treatment of primary and metastatic cancers of the liver. Operating in the surgical and medical instrument manufacturing industry within the broader manufacturing sector, Delcath develops and commercializes proprietary drug–device technologies designed to deliver high-dose chemotherapy directly to the liver while limiting systemic exposure and related side effects.

The company’s business centers on its hepatic delivery technologies, which are used in a procedure known as percutaneous hepatic perfusion (PHP). According to company disclosures, Delcath operates through a single reportable segment that encompasses the research, development, manufacture, and distribution of hepatic delivery systems for use in the treatment of specific liver-related conditions. The company conducts business in the United States and Europe.

Core products and technology

Delcath’s proprietary products are HEPZATO KIT™ and the CHEMOSAT® Hepatic Delivery System (HDS) for Melphalan. Both are designed to administer high-dose melphalan chemotherapy to the liver during a PHP procedure while controlling systemic exposure.

• HEPZATO KIT (HEPZATO (melphalan) for Injection/Hepatic Delivery System): In the United States, HEPZATO KIT is treated as a combination drug and device product and is regulated and approved for sale as a drug by the U.S. Food and Drug Administration (FDA. The kit combines the chemotherapeutic drug melphalan with Delcath’s proprietary Hepatic Delivery System (HDS).
• CHEMOSAT Hepatic Delivery System (HDS) for Melphalan: 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. It has been used at major medical centers in percutaneous hepatic perfusion procedures to treat a range of cancers of the liver.

The HDS component is used to isolate hepatic venous blood from the systemic circulation while simultaneously filtrating the hepatic venous blood during melphalan infusion and washout. Company materials state that this approach results in loco-regional delivery of a relatively high melphalan dose that can potentially induce a clinically meaningful tumor response with minimal hepatotoxicity and reduced systemic exposure.

Therapeutic focus and indications

Delcath’s primary therapeutic focus is on metastatic uveal melanoma (mUM) and other cancers involving the liver. The company describes itself as focused on the treatment of primary and metastatic liver cancers, with a particular emphasis on liver-dominant metastatic disease.

In the United States, HEPZATO KIT is approved as a liver-directed treatment for adult patients with metastatic uveal melanoma 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. The company notes that full prescribing information, including a boxed warning, applies to the product.

In Europe, CHEMOSAT has been used in PHP procedures at major medical centers to treat a wide range of cancers of the liver. Published data cited in company news releases describe use of CHEMOSAT in liver-dominant metastatic uveal melanoma and other liver metastases, with studies examining survival outcomes, disease control, and the role of repeated PHP cycles.

Clinical evidence and research activity

Delcath’s technologies are supported by a body of clinical and real-world evidence referenced in its public communications. The company highlights:

• A Phase 3 FOCUS study of Melphalan/Hepatic Delivery System in patients with unresectable metastatic uveal melanoma, which led to the FDA approval of HEPZATO. Subgroup analyses of this study have been published, assessing efficacy and safety across factors such as age, sex, geographic region, tumor burden, extent of liver involvement, extrahepatic lesions, baseline LDH, and prior therapies.
• The CHOPIN Phase 2 trial, sponsored by Leiden University Medical Center, evaluating CHEMOSAT with the immune checkpoint inhibitors ipilimumab and nivolumab in metastatic uveal melanoma. Company disclosures report a significant improvement in one-year progression-free survival for the combination versus CHEMOSAT alone.
• A 10-year single-center experience from Asklepios Hospital Barmbek in Hamburg, Germany, using CHEMOSAT for liver-dominant metastatic uveal melanoma, reporting safety and efficacy outcomes over multiple PHP procedures.
• A retrospective analysis from the University of Tübingen examining long-term survivors with liver metastases from uveal melanoma, which underscores the potential benefits of early use of liver-directed therapies, including PHP, in achieving long-term survival.
• An expert narrative review in the Journal of Vascular and Interventional Radiology summarizing the rationale, technique, patient selection, clinical outcomes, and research directions for PHP with melphalan using HEPZATO KIT, and emphasizing its role as an FDA-approved liver-directed therapy for unresectable hepatic metastases from uveal melanoma with limited extrahepatic disease.

These publications and analyses, as described in Delcath’s news releases, collectively present data on objective response rates, progression-free survival, overall survival, disease control rates, safety profiles, and the impact of tumor burden and treatment sequencing on outcomes in metastatic uveal melanoma and liver-dominant disease.
