Inclusion Criteria
  • Men and women, at least 18 years of age;
  • World Health Organization (WHO) Performance Status 0 or 1;
  • Histologically confirmed, stage pT3-4 cutaneous melanoma (Breslow thickness >2.0mm; according to AJCC criteria 8th edition);
  • Having ≥44% risk for SN positivity as assessed by the MIA Sentinel Node Metastasis Risk prediction tool (melanomarisk.org.au/SNLForm)1;
  • Excision of primary melanoma took place ≤4 weeks prior to informed consent;
  • Naïve for re-excision of the primary melanoma site and for sentinel node procedure;
  • No other solid, distantly metastasized malignancies, no hematological malignancies and no malignancies for which systemic treatment is administered within 6 months prior to study inclusion;
  • No prior immunotherapy targeting CTLA-4, PD-1, PD-L1 or LAG-3;
  • No prior targeted therapy with BRAF/MEK inhibition;
  • No immunosuppressive medications within 6 months prior to study inclusion (steroids equivalent to prednisolone ≤10 mg are allowed);
  • Screening laboratory values must meet the following criteria: WBC ≥2.0x109/L, neutrophils ≥1.5x109/L, platelets ≥100x109/L, hemoglobin ≥5.5 mmol/L, creatinine ≤1.5xupper limit of normal (ULN), AST ≤1.5x ULN, ALT ≤1.5x ULN, bilirubin ≤1.5x ULN (except for subjects with Gilbert syndrome who must have a total bilirubin <3.0 mg/dL)
  • LDH level ≤ULN;
  • Women of childbearing potential (WOCP) must use appropriate method(s) of contraception, i.e. methods with a failure rate of <1% per year when used consistently and correctly, to avoid pregnancy for 23 weeks post last ipilimumab + nivolumab infusion;
  • Patient willing and able to understand the protocol requirements and comply with the treatment schedule, scheduled visits, electronic patient outcome reporting, tumor biopsies and extra blood withdrawal during screening, and other requirements of the study;
Exclusion Criteria
  • Acral, uveal/ocular, mucosal or or lentigo maligna melanoma;
  • A concurrent second, primary melanoma;
  • Regionally or distantly metastasized melanoma, including in-transit metastases and macroscopic lymph node metastases;
  • No suspect lymph nodes detectable by ultrasound in the draining lymph node region(s);
  • Subjects with any active autoimmune disease or a documented history of autoimmune disease, or history of syndrome that required systemic steroids or immunosuppressive medications. Subjects with resolved childhood asthma/atopy, type I diabetes mellitus, residual hypothyroidism due to autoimmune thyroiditis only requiring hormone replacement, skin disorders (such as vitiligo, psoriasis, or alopecia) not requiring systemic treatment, are permitted to enroll;
  • Prior surgery, including prior sentinel node procedure or lymph node dissection, in the affected lymph node region(s);
  • Prior radiotherapy targeting the affected lymph node region(s);
  • Subjects will be excluded if they test positive for hepatitis B virus surface antigen (HBsAg) or hepatitis C virus ribonucleic acid (HCV antibody), indicating acute or chronic infection. Subjects treated and being at least one year free from HCV are allowed to participate;
  • Subjects will be excluded if they have known history of testing positive for human immunodeficiency virus (HIV) or known acquired immunodeficiency syndrome (AIDS);
  • Subjects with history of allergy to study drug components or history of severe hypersensitivity reaction to monoclonal antibodies;
  • Subjects with underlying medical conditions or active infection that, in the investigator's opinion, will make the administration of study drug hazardous or obscure the interpretation of toxicity or adverse events;
  • Women who are pregnant or breastfeeding;
  • Concurrent medical condition requiring the use of immunosuppressive medications, or immunosuppressive doses of systemic or absorbable topical corticosteroids >10 mg prednisolone daily equivalent;
  • Use of other investigational drugs before study drug administration 30 days or 5 half-times before study inclusion;
  • Psychological, familial, sociological, or geographical conditions that potentially hamper compliance with the study protocol and follow-up schedule; those conditions should be discussed with the subject before registration in the trial.

Primary Outcome Measures
NameTimeMethod
Feasibility of application of studytreatmentUp to 100 days after treatment

Feasibility as measured by the adherence to the timelines in the study protocol. A treatment arm will be declared as not feasible if 3/11 or 6/24 patients cannot adhere to the planned time of surgery due to treatment-related adverse events.

Rate of effectiveness of the studytreatmentUp to 5 years after randomization

Pathological response as assessed by blinded central review, adapted from the INMC criteria, including pCR, near-pCR, or pPR (0-50% residual viable tumor in resection material), or sentinel node negativity for melanoma.

Secondary Outcome Measures
NameTimeMethod
treatment-related adverse eventsUp to 5 years after randomization

Frequency and duration of all grade and grade 3-5, treatment-related adverse events according to CTCAE 5.0;.

EFSUp to 5 years after start of treatment

defined as time from start of treatment to melanoma progression (irresectable stage II or III, or stage IV disease), melanoma recurrence, treatment-related death, or melanoma-related death, whichever occurs first;

DMFSUp to 5 years after randomization

defined as time between date of surgery (re-excision and SN-procedure) and date of first distant metastasis, treatment-related death or melanoma-related death, whichever occurs first;

OSUp to 5 years after start of treatment

defined as time between date of start of treatment and date of death;
