Retrospective Analysis of Changes in Patients with Metastatic Uveal Melanoma treated with Chemosat Hepatic Delivery System
Results Support that Utilizing Delcath's HDS to Administer High-Dose Melphalan to the Liver Is Well Tolerated by Patients
NEW YORK, Dec. 7, 2023 /PRNewswire/ -- Delcath Systems, Inc. (Nasdaq: DCTH), an interventional oncology company focused on the treatment of primary and metastatic cancers of the liver, today announced the publication of a clinical study in the journal Melanoma Research. The publication, entitled "Quality of Life After Melphalan Hepatic Perfusion for Uveal Melanoma", was based on an independent clinical study conducted by investigators from University Hospital Southampton, UK and focused on the impact of melphalan percutaneous hepatic perfusion treatment on the quality of life (QoL) of patients with metastatic uveal melanoma. Melphalan Hepatic Perfusion, also known as Percutaneous Hepatic Perfusion (PHP), utilizes CHEMOSAT, Delcath's proprietary European CE Marked Hepatic Delivery System (HDS), to administer high-dose melphalan to the liver, while controlling systemic exposure and associated side effects.
Uveal melanoma usually shows a liver-dominant metastatic spread and is often treated with liver directed therapies. While the safety and efficacy profile of utilizing Delcath's HDS to administer high-dose melphalan to the liver is favorable and well established based on results from several clinical studies, the impact of this treatment on QoL has not been widely investigated. When assessing the value of a treatment, clinicians often weigh its efficacy and effect on overall survival against any negative impact of the treatment on QoL.
Investigators used the FACT-G (Functional Assessment of Cancer Therapy – General) questionnaire which has been specifically developed for and validated in oncology patients. The FACT-G questionnaire consists of 4 subdomains: physical (PWB), social (SWB), emotional (EWB) and functional (FWB) wellbeing.
The study included 20 patients with metastatic uveal melanoma treated at the University Hospital Southampton between August 2020 and January 2023. The FACT-G questionnaire was administered pre-treatment and post-treatment on day 1, day of discharge, day 7, 14 and 28. Immediately following treatment, PWB and FWB decreased relative to baseline; by day 14 no residual significant difference was observed and on day 28 overall scores were almost at baseline. Interestingly, an improvement over baseline in EWB was observed by day 28.
The authors conclude their results support the growing body of evidence that utilizing Delcath's HDS to administer high-dose melphalan to the liver is well tolerated by patients does not negatively effect their quality of life. A link to the publication's abstract can be found here.
"The publication of these results by independent investigators supports the rationale for the percutaneous hepatic perfusion procedure, whether utilizing melphalan delivered by Delcath's CE marked Chemosat or the FDA approved HEPZATO KIT, as an important treatment option for patients with liver-dominant uveal melanoma," said Dr. Vojo Vukovic, Delcath's Chief Medical Officer. "We look forward to making this treatment option available to patients in the US in January 2024."
About Chemosat and HEPZATO KIT
CHEMOSAT Hepatic Delivery System for Melphalan percutaneous hepatic perfusion (PHP) is designated a class lll medical device under the Medical Device Regulation for use in Europe and the United Kingdom. The Hepatic Delivery System (HDS) is designed to administer high-dose chemotherapy to the liver while controlling systemic exposure and associated side effects during a PHP procedure. The use of the HDS allows a healthcare provider team to surgically isolate the liver while the hepatic venous blood is filtered during melphalan infusion and subsequent washout during a Percutaneous Hepatic Perfusion (PHP) procedure. PHP, which can only be performed with Delcath's HDS, results in loco-regional delivery of a relatively high melphalan dose. For more information regarding CHEMOSAT and its use, please visit Chemosat.com.
HEPZATO KIT (melphalan for Injection/Hepatic Delivery System), approved for use in the United States by FDA, is a combination drug/device product which administers HEPZATO (melphalan) directly to the liver through the HDS, which permits higher drug exposure in target tissues while limiting systemic toxicity.
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.
