Hepzato Kit and Opdualag for Metastatic Melanoma and Liver Metastasis
What this study is about
This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) in the first line setting in patients with metastatic melanoma with liver metastasis is safe, tolerable, and will have a synergistic effect leading to improved clinical outcomes compared to the historic group of participants of patients with liver metastasis treated with combination immune checkpoint inhibitor therapy.
View original scientific description
This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) in the first line setting in patients with metastatic melanoma with liver metastasis is safe, tolerable, and will have a synergistic effect leading to improved clinical outcomes compared to the historic cohort of patients with liver metastasis treated with combination immune checkpoint inhibitor therapy.
Interventions
DRUG
Nivolumab and Relatlimab
Relatlimab is a human IgG4 LAG-3 blocking antibody. Nivolumab is a human IgG4 PD-1 blocking antibody. Nivolumab 480 mg and relatlimab 160 mg in a fixed-dose combination will be administered on Day 1 of each 28-day cycle that the participant is on treatment and will be given for up to 2 years from start of treatment.
DEVICE
Melphalan
The recommended HEPZATO dose is 3 mg/kg based on ideal body weight (IBW), infusion every 6 to 8 weeks for up to 2 total infusions
Primary outcome measures
Incidence and Severity of Dose Limiting Toxicities (DLTs)
Time frame: up to 12 weeks
A DLT is defined as any grade 4+ non-hematologic event lasting greater than 3 days (despite appropriate medical management) considered possibly related to study treatment (HEPZATO KIT™ or Opdualag™) within 12 weeks of Cycle 1 Day 1.
Incidence of Treatment-Emergent Adverse Events
Time frame: up to 2 years
Incidence of Serious Treatment-Emergent Adverse Events
Time frame: up to 2 years
Number of Participants that Discontinue Treatment due to Adverse Events
Time frame: up to 2 years
Overall Response Rate (ORR)
Time frame: After treatment plus follow up for 2 years (up to 4 years)
The objective response rate is the proportion of all participants with confirmed Partial Response (PR) or Complete Response (CR) according to RECIST 1.1, from the start of treatment until disease progression/recurrence (taking as reference for progressive disease the smallest measurements recorded since the start of treatment).
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Histologically or cytologically confirmed metastatic melanoma with liver metastasis (LM). Liver biopsy positive for presence of melanoma metastases is required.
- Systemic treatment naïve in the unresectable/metastatic setting - prior adjuvant anti-programmed cell death-1 (anti-PD-1) and BRAF/MEK targeted therapy is allowed but must be greater than 6 months from the last treatment.
- Evaluable/measurable disease according to RECIST v1.1.
- Demonstrate adequate organ function; all screening labs to be obtained within 28 days prior to registration.
- Patients must weigh greater than or equal to 35 kilograms (due to possible size limitations with respect to percutaneous catheterization of the femoral artery and vein using the Delcath Hepatic Delivery System).
Exclusion criteria
- Prior treatment with HEPZATO KIT™ or nivolumab and relatlimab (Opdualag™)
- Radiotherapy is permitted within 30 days prior to C1D1 as long as radiation is given with palliative intent and towards a non-target lesion.
- History of hypersensitivity or treatment discontinuation due to grade 3+ immune-related adverse events (irAEs) from prior anti-PD-(L)1 therapy. Patients who are able to successfully resume immune checkpoint therapy without recurrence of grade 3 irAEs are eligible to participate.
- Symptomatic or uncontrolled brain metastases, leptomeningeal disease, or spinal cord compression not definitively treated with surgery or radiation.
- Prednisone use greater than or equal to 10 mg/d or equivalent
- Organ transplant recipients
Where
- Madison, Wisconsin

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
