Study summary

This study is being done to see if combining HEPZATO KIT™ with nivolumab and relatlimab (Opdualag™) 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.

Read the detailed description

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • or cytologically confirmed melanoma with liver metastasis (LM). Liver positive for presence of melanoma metastases is required.

  • Evaluable/ according to 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

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.

Terms in these criteria, in plain language(9)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Metastases

Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.

Biopsy and archival tissue

A biopsy takes a small piece of tissue to examine. “Archival tissue” is a sample already taken, for example at diagnosis, and kept by the hospital.

Whether a stored sample will do depends on when it was taken, how much there is and what the study needs. Ask whether the study accepts your stored sample or needs a new biopsy.

PD-1, PD-L1 and checkpoint inhibitors

PD-1, PD-L1 and CTLA-4 are proteins that act as brakes on the immune system. Checkpoint inhibitors, such as pembrolizumab or nivolumab, block them so the immune system can attack a cancer.

PD-L1 can also be measured in a tumour sample. Some scores count stained tumour cells only (TPS); others also count certain immune cells (CPS). The study names the score and the minimum it uses.

Measurable disease

The amount of disease can be tracked with a defined measurement, so the study can see whether it shrinks or grows. It might be a tumour measured on a scan or, in some blood cancers such as myeloma, a marker measured in blood or urine.

The criteria or the study team say which measurement counts — having no tumour visible on a scan does not by itself rule you out.

RECIST

The standard rules for measuring tumours on CT or MRI scans, to tell whether a cancer is shrinking, stable or growing during treatment.

“Measurable disease per RECIST 1.1” usually means at least one tumour 10 mm or more at its longest on a CT scan, or a lymph node 15 mm or more across its short axis.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Brain metastases

Cancer deposits in the brain from a cancer that started elsewhere in the body (CNS metastases include the spinal cord).

Studies differ: some leave out any brain metastases, some accept ones treated and stable for some weeks. Check what this study allows.

Leptomeningeal disease

Cancer that has spread to the leptomeninges, the thin layers covering the brain and spinal cord, and the fluid between them. It is not the same as brain metastases.

Criteria often treat it separately, and many studies leave it out even where treated brain metastases are allowed.

    Participants with Metastatic Melanoma

    Drug: Nivolumab and Relatlimab · Device: Melphalan

Interventions

  • DrugNivolumab 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.

    Also known as: Opdualag

What researchers measure

Primary outcomes

  1. Incidence and Severity of Dose Limiting Toxicities (DLTs)

    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.

    Time frame: up to 12 weeks

  2. Incidence of Treatment-Emergent Adverse Events

    Time frame: up to 2 years

  3. Incidence of Serious Treatment-Emergent Adverse Events

    Time frame: up to 2 years

  4. Number of Participants that Discontinue Treatment due to Adverse Events

    Time frame: up to 2 years

  5. Overall Response Rate (ORR)

    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).

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

Secondary outcomes

  1. ORR in Hepatic and Non-Hepatic Lesions

    The proportion of all participants with confirmed PR or 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) in Hepatic and Non-Hepatic Target Lesions.

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

  2. Disease Control Rate (DCR)

    The disease control rate is the proportion of all subjects with SD for 8 weeks, or PR, or 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).

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

  3. Progression Free Survival (PFS)

    A measurement from the date of randomization until the criteria for disease progression is met as defined by RECIST 1.1 or death occurs. Participants who have not progressed will be right-censored at the date of the last disease evaluation.

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

  4. Overall Survival (OS)

    Overall survival is defined by the date of randomization to date of death from any cause.

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

  5. Duration of Response (DOR)

    Duration of overall response-the period measured from the time that measurement criteria are met for complete or partial response (whichever status is recorded first) until the date that recurrent or progressive disease is objectively documented (taking as reference for progressive disease the smallest measurements recorded since treatment started).

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

  6. Number of Participants with Tumor Reduction at any time

    Time frame: After treatment plus follow up for 2 years (up to 4 years)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
