Inclusion Criteria:

  • In order to be eligible for participation in this trial, the subject must meet all the following:

    1. Pathologically documented unresectable melanoma, AJCC Stage III or IV. Subjects must have histological or cytological confirmed diagnosis of unresectable melanoma with progressive locally advanced or metastatic disease.
    2. Subjects must be refractory to anti-PD-1 monoclonal antibodies (pembrolizumab or nivolumab either as monotherapy or in combination with other approved checkpoint inhibitors or targeted therapies according to their approved label) and subjects must meet all of the following criteria:

      1. Received at least 4 doses of anti-PD1 mAb (minimum dose of 2 mg/kg or fixed dose of 200 mg given Q3W for pembrolizumab; minimum dose of 240 mg given Q2W for nivolumab in monotherapy; minimum dose of 1 mg/kg given Q3W for nivolumab in combination with ipilimumab)
      2. Progressive disease after anti-PD1 mAb will be defined according to RECIST v1.1.
      3. Documented disease progression within 24 weeks of the last dose of anti-PD1 mAb.
    3. Resolution/improvement of anti-PD1 mAb-related AEs

      1. No history of common toxicity criteria adverse events (CTCAE) Grade 4 irAEs from anti-PD1 mAb.
      2. No history of CTCAE Grade 3 requiring steroid treatment (>10 mg/day prednisone or equivalent dose) for >12 weeks or CTCAE Grade 2 pneumonitis regardless of steroid treatment.
      3. Minimum of 4 weeks (washout period) from the last dose of anti PD1 mAb.
    4. Prior treatment with an approved BRAF inhibitor if BRAF V600 mutation-positive.
    5. Age ≥ 18 years of age on day of signing informed consent.
    6. Has a performance status of 0 or 1 on the ECOG Performance Scale.
    7. Have measurable disease based on RECIST v1.1, with at least one anatomically distinct lesion. Lesion or lesions must meet all the following baseline criteria:

      1. Accessible for electroporation,
