Publication of Results from Pivotal FOCUS Study in Metastatic Uveal Melanoma Patients treated with HEPZATO KIT
Delcath Systems, an interventional oncology company, announced positive results from the pivotal Phase 3 FOCUS study of HEPZATO KIT in patients with unresectable metastatic Uveal Melanoma. The study showed a significantly higher Overall Response Rate of 36.3% compared to historical controls, with a Disease Control Rate of 73.6% and a Complete Response Rate of 7.7%. Secondary endpoints included Duration of Response, Progression-free Survival, and Overall Survival. The study also reported comparable safety and tolerability with no treatment-related deaths.
The FOCUS study demonstrated a significantly higher Overall Response Rate of 36.3% compared to historical controls, showcasing the efficacy of HEPZATO KIT in treating metastatic Uveal Melanoma patients.
The Disease Control Rate of 73.6% and Complete Response Rate of 7.7% further highlight the effectiveness of HEPZATO KIT in managing unresectable mUM.
The study showed encouraging secondary endpoints, including Duration of Response (14 months), Progression-free Survival (9 months), and Overall Survival (20.5 months), providing comprehensive data on the treatment's effectiveness.
Safety and tolerability of HEPZATO KIT were comparable to published clinical experience, with common adverse events effectively managed with standard supportive care and no treatment-related deaths observed.

The Food and Drug Administration (FDA) approved HEPZATO KIT on August 14, 2023 based on the results from the pivotal FOCUS study. A total of 91 patients with unresectable mUM were treated with HEPZATO KIT at 23 treatment centers in the US and
The FOCUS study was designed to provide a robust evaluation of efficacy and safety of HEPZATO KIT treatment, and enrolled a heterogeneous mUM patient population, including treatment-naïve and pretreated patients, patients with and without extrahepatic disease and patients with a range of baseline tumor burden.
The primary efficacy endpoint of the FOCUS study was Overall Response Rate (ORR), which was
Secondary efficacy endpoints included Duration of Response (DOR), median Progression-free Survival (mPFS) and median Overall Survival (mOS), which were 14, 9 and 20.5 months, respectively.
Safety and tolerability of HEPZATO KIT treatment reported in the FOCUS study was comparable with published clinical experience with Chemosat in
"My team at the Moffitt Cancer Center and I are very excited about the publication of results from the FOCUS study. The study results are consistent with data obtained from previous clinical studies, as well as our own experience with percutaneous hepatic perfusion (PHP) with more than 200 treatments performed at Moffitt over the past 15 years," said Dr. Jonathan Zager, MD Chief Academic Officer and Director of Regional Therapies at Moffitt Cancer Center. "Since HEPZATO KIT became available in January, the treatment has become the liver directed standard of care for appropriate patients with mUM at our institution."
"Results from the pivotal FOCUS study demonstrate that the PHP procedure, whether utilizing the FDA approved HEPZATO KIT or melphalan delivered by the Chemosat device available in
The vast majority of patients with mUM will have liver metastases, often leading to liver failure, and the National Comprehensive Cancer Network guidelines recommend liver-directed therapies be considered for the treatment of mUM. HEPZATO is the only liver-directed treatment for unresectable mUM patients approved by the FDA.
