Delcath Systems, Inc. (Nasdaq: DCTH) (the “Company” or “Delcath”), an interventional oncology company specializing in the treatment of primary and metastatic liver cancers, today announced the publication of a retrospective study by independent investigators in the Annals of Surgical Oncology. The study, titled “Hepatic and Overall Progression-Free Survival After Percutaneous Hepatic Perfusion (PHP) as First-Line or Second-Line Therapy for Metastatic Uveal Melanoma,” was conducted by researchers at Moffitt Cancer Center in Tampa, Florida. The 30-patient study reported that Delcath’s HEPZATO KIT™ (melphalan/Hepatic Delivery System (HDS)) provided better disease control in the liver and improved progression-free survival in patients with hepatic metastases from uveal melanoma, compared to both immunotherapy and other liver-directed therapies.
Key Findings from the Study:
- Overall Survival (OS): The study reported median OS of 22.4 months for patients treated with HEPZATO KIT as a first-line therapy (N=17) and 18.4 months as a second-line therapy (N=6).
- Hepatic Progression-Free Survival (hPFS): Patients receiving HEPZATO KIT as first-line therapy had a median hPFS of 17.6 months (N=17), compared to 8.8 months (N=6) for immunotherapy and 9.2 months (N=7) for other liver-directed therapies. When used as a second-line therapy, HEPZATO KIT resulted in a median hPFS that was not reached (N=6), showing better outcomes than immunotherapy (14.7 months, N=5) and other liver-directed therapies (7.5 months, N=3) in this patient cohort.
- Progression-Free Survival (PFS): The median overall PFS was 15.4 months (N=17) for patients receiving HEPZATO KIT as first-line therapy, compared to 8.8 months (N=6) for immunotherapy and 9.2 months (N=7) for other liver-directed therapies. In the second-line setting, HEPZATO KIT resulted in a median PFS of 22.2 months (N=6), compared to 14.7 months (N=5) for immunotherapy and 7.5 months (N=3) for other liver-directed therapies, reflecting longer disease control in this group.
Jonathan Zager, MD Chief Academic Officer and Director of Regional Therapies at Moffitt Cancer Center, remarked, “The findings from this study reaffirm the critical role of melphalan/HDS in managing liver-dominant metastatic uveal melanoma. These results highlight the potential benefits melphalan/HDS offers to patients, particularly in the context of first- and second-line treatments. My team is committed to further exploring the potential of combining melphalan/HDS with systemic therapies to continue improving patient outcomes.”
