Description of Business | Description of Business Delcath Systems, Inc. (“Delcath” or “the Company”) is an interventional oncology company focused on the treatment of cancers primary or metastatic to the liver. The Company’s lead product, the HEPZATO TM KIT (melphalan for Injection/Hepatic Delivery System), a drug/device combination product (“HEPZATO” or “HEPZATO KIT”), was approved by the US Food and Drug Administration (the “FDA”) on August 14, 2023, indicated as a liver-directed treatment for adult patients with 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 first commercial use of the HEPZATO KIT for the treatment of metastatic uveal melanoma (“mUM”) occurred in January 2024. In the United States, HEPZATO is considered a combination drug and device product and is regulated as a drug by the FDA. Primary jurisdiction for regulation of HEPZATO has been assigned to the FDA’s Center for Drug Evaluation and Research. The FDA has granted Delcath six orphan drug designations (five for melphalan in the treatment of patients with ocular (uveal) melanoma, cutaneous melanoma, intrahepatic cholangiocarcinoma, hepatocellular carcinoma, and neuroendocrine tumor indications and one for doxorubicin in the treatment of patients with hepatocellular carcinoma). The Company has sufficient raw material and component constituent parts of the HEPZATO KIT to meet anticipated demand and it intends to manage supply chain risk through stockpiled inventory and, where commercially reasonable, contracting with multiple suppliers for critical components. In Europe, the hepatic delivery system is a stand-alone medical device having the same device components as HEPZATO, but without the melphalan hydrochloride and is approved for sale under the trade name CHEMOSAT Hepatic Delivery System for Melphalan (“CHEMOSAT”), where it has been used at major medical centers to treat a wide range of cancers in the liver. On February 28, 2022, CHEMOSAT received Medical Device Regulation (“MDR”) certification under the European Medical Devices Regulation (EU) 2017/745, which may be considered by jurisdictions when evaluating reimbursement. To support the New Drug Application for HEPZATO the Company conducted the FOCUS Clinical Trial for Patients with metastatic hepatic dominant Uveal Melanoma (the “FOCUS Trial”), a global registration clinical trial that investigated objective response rate in patients with mUM. On May 6, 2024, the Company announced the publication of results from the pivotal FOCUS Trial in the journal Annals of Surgical Oncology. The current focus of the Company’s clinical development program is to generate clinical data for CHEMOSAT and HEPZATO either as monotherapy or in combination with immunotherapy. The Company expects that this will support increased clinical adoption of and reimbursement for CHEMOSAT in Europe, and to support reimbursement in various jurisdictions, including the United States. In addition to HEPZATO’s use to treat mUM, the Company believes that HEPZATO has the potential to treat other cancers in the liver, such as metastatic colorectal cancer, metastatic breast cancer, metastatic neuroendocrine tumors and intrahepatic cholangiocarcinoma. The Company’s IND application for a Phase 2 clinical trial evaluating HEPZATO in combination with standard of care (SOC) for mCRC was cleared by the FDA in December 2024. The Phase 2 trial will evaluate the safety and efficacy of HEPZATO in combination with trifluridine-tipiracil and bevacizumab compared to trifluridine-tipiracil and bevacizumab alone in patients with liver-dominant mCRC receiving third-line treatment. Approximately 90 patients will be enrolled in this randomized, controlled trial. The study will take place at more than 20 sites across the United States and Europe, with patient enrollment expected to begin in the second half of 2025. The trial’s primary endpoint, hepatic progression-free survival (hPFS), is anticipated to read out by the end of 2027, while overall survival (OS), a secondary endpoint, is expected in 2028. The Company estimates that the total addressable market (TAM) for liver-dominant mCRC receiving third-line treatment is between 6,000 and 10,000 patients annually in the United States. This market includes patients who present with significant liver disease burden, with liver-dominant status determined through radiological and clinical criteria. By targeting this patient population, the Company aims to provide a novel treatment option for those with limited therapeutic alternatives. The Company also plans to begin a study evaluating HEPZATO in combination with SOC for liver-dominant metastatic breast cancer in 2025. The Company believes that those and similar disease states are areas of unmet medical needs that represent significant market opportunities. Risks and Uncertainties The Company is subject to risks common to companies in the biopharmaceutical industry including, but not limited to, the risks associated with developing product candidates and successfully launching and commercializing its drug/device combination products, the Company’s ability to obtain regulatory approval of its such produ cts in the United States and other geography markets, the uncertainty of the broad adoption of its approved products by physicians and consumers, and significant competition. In addition, high rates of inflation have resulted in the United States Federal Reserve raising interest rates. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may further increase economic uncertainty and heighten these risks. Furthermore, if additional banks and financial institutions enter receivership or become insolvent in the future in response to financial conditions affecting the banking system and financial markets, the Company or its partners’ ability to access existing cash, cash equivalents and investments may be threatened and could have a material adverse effect on the Company’s business and financial condition, including the Company’s ability to access additional capital on favorable terms, or at all, which could in the future negatively affect the Company’s ability to pursue its business strategy. Liquidity The accompanying consolidated financial statements have been prepared on a basis which assumes that the Company will continue as a going concern and contemplates the realization of assets and the satisfaction of liabilities and commitments in the normal course of business. The substantial doubt previously disclosed has been alleviated due to the cash on hand, cash equivalents and investments held on December 31, 2024 and through the issuance of this Annual Report on Form 10-K. In 2024, due to the commercialization of HEPZATO and increased demand for CHEMOSAT, the Company was able to partially fund operations from the revenue produced by the sales of these products. Further increases of cash on hand, cash equivalents and investments were due to the sales of common stock through stock option exercises and the March 2024 PIPE plus exercises of Series E, Series E-1, Tranche B and prefunded warrants. On December 31, 2024, the Company had cash and cash equivalents totaling $32.4 million and short-term investments totaling $20.8 million, as compared to cash, cash equivalents and restricted cash totaling $12.7 million and short-term investments totaling $19.8 million at December 31, 2023. During the twelve months ended December 31, 2024, the Company used $18.7 million of cash in its operating activities and $10.6 million for principal payments. The Company believes that the current cash on hand, cash equivalents, investments and revenue produced by sales will be sufficient to support current operations through at least 12 months from the issuance of the consolidated financial statements included in this Annual Report on Form 10-K. Actual future liquidity and capital requirements will depend on numerous factors, including the initiation and progress of clinical trials and research and product development programs; obtaining regulatory approvals and complying with applicable laws and regulations; the timing and effectiveness of product commercialization activities, including marketing arrangements; the timing and costs involved in preparing, filing, prosecuting, defending and enforcing intellectual property rights; the resolution of any disputes with third parties; and the effect of competing technological and market developments. The Company’s capital commitments over the next twelve months include $6.1 million to satisfy accounts payable, accrued expenses, current lease liabilities and current medac settlement. Additional capital commitments beyond the next twelve months include (a) $1.3 million of lease liabilities; and (b) $0.8 million for settlement of litigation with medac. For more information on the medac settlement, see Note 15 - “Commitment and Contingencies - Litigation, Claims and Assessments - medac Matter”.
