Outcome Measures
Primary Outcomes (1)
Intratumoral CXCL13⁺ CD8⁺ T-cell infiltration following Percutaneous Hepatic Perfusion (PHP)
Change in the percentage of CXCL13⁺ CD8⁺ T cells in tumor biopsies between Day 0 (pre-treatment) and Day 28-42 (approximately 3-4 weeks post-treatment), as measured by single-cell RNA sequencing.
3-4 weeks post treatment
Secondary Outcomes (5)
Antigen-presenting cell (APC) populations and their activation state in the tumor microenvironment.
28-42 day tumor biopsies
T-cell infiltration in tumor and adjacent hepatic parenchyma.
28-42 days post treatment
Single-cell RNA sequencing derived frequency of macrophages and myeloid-derived suppressor cells (MDSCs)
28-42 days post treatment
Single-cell RNA sequencing derived phenotype of macrophages and myeloid-derived suppressor cells (MDSCs)
28-42 days post treatment
Immune cell populations with molecular and biochemical features of tissue and peripheral blood.
28-42 days post treatment.

Eligibility Criteria
You may qualify if:
- Patient has histologically or cytologically confirmed diagnosis of uveal melanoma metastatic to the liver and is determined to be a candidate for percutaneous hepatic perfusion with melphalan
- The subject has read, signed and dated the Informed Consent Form (ICF), having been advised of the risks and benefits of the trial in a language understood by the subject.
- Age \> 18 years at date of informed consent signature having the ability to comply with the protocol.
- Contrast-enhanced cross-sectional imaging of the abdomen (either CT or MRI) obtained within two months prior to study enrollment
- Measurable metastatic disease. Subject must have at least one site of metastatic disease ≥ 1 cm in size and amenable to percutaneous image-guided biopsy
- Life expectancy \> 12 weeks.
- Eastern Cooperative Oncology Group (ECOG) Performance Status of 0 or 1
- Laboratory requirements:
- Absolute neutrophil count (ANC) \> 1 x 109/L
- Platelets \> 75 x 109/L
- Alanine aminotransferase (ALT) / Aspartate aminotransferase (AST) \< 5 x ULN
- Total bilirubin \<3 mg/dL
- International normalized ratio (INR) \<1.7
- Glomerular filtration rate (GFR) \>30 ml/min
You may not qualify if:
- Lesion to undergo biopsy cannot have undergone prior radiation therapy or other locoregional therapy
- Continued adverse events from a previously administered chemotherapeutic agents. Grade 1 adverse events and ongoing toxicities such as alopecia are exempt
- Treatment with systemic corticosteroids exceeding the equivalent of 10 mg/day of prednisone or other systemic immunosuppressive medications (including but not limited to prednisone, dexamethasone, cyclophosphamide, azathioprine, methotrexate, and anti-tumor necrosis factor \[anti-tumor necrosis factor (TNF)\] agents) within 2 weeks prior to Day 1, or anticipated requirement for systemic immunosuppressive medications exceeding the equivalent of 10 mg/day of prednisone during the trial
- Patients who receive acute, low-dose, systemic corticosteroid medications (e.g., a one-time dose of dexamethasone for nausea) or for prevention of hypersensitivity reactions to contrast agents may be enrolled in the trial.
- Anticoagulant or anti-platelet medication that cannot be interrupted prior to biopsy
- Pregnant or lactating
- Any other diseases, metabolic dysfunction, physical examination finding, or clinical laboratory finding giving reasonable suspicion of a disease or condition that contraindicated the use of an investigational drug or that could affect the interpretation of the results or render the patient at high risk from treatment complications.
- Treatment with systemic immunostimulatory agents (including but not limited to interferon(IFN)s, interleukin \[IL\]-2) within 6 weeks or five half- lives of the drug, whichever was shorter, prior to Day 1.
- Treatment with immune checkpoint blockade therapies, including anti-CTLA-4, anti-PD-1, and anti-PD-L1 therapeutic antibodies, anti-LAG-3 antibodies, within the past three months. Prior treatment with tebentafusp is allowed with no washout period required.
- Treatment with any investigational systemic medication within at least one month prior to biopsy. If an investigational agent is an immune checkpoint inhibitor, a three-month washout is required. Prior treatment with Darovasertib and Crizotinib is allowed with no washout period required.
- Signs or symptoms clinically significant of infection within 2 weeks prior to Day 1.
