Criteria

Inclusion Criteria:

Subjects enrolled in the study must meet all of the following inclusion criteria to be eligible.

  1. Histopathologically-confirmed diagnosis of malignant melanoma that is metastatic or unresectable at Screening.
  2. Known BRAF mutation status; if BRAF V600 mutation positive, must have had prior treatment with a local Health Authority approved BRAF inhibitor, with or without mitogen-activated protein kinase inhibitor. Patients with BRAF V600 mutations who refuse a BRAF inhibitor will not be eligible.
  3. Refractory to PD-1 blockade either as monotherapy or in combination with other therapies, as defined by the following criteria:

    2. Have PD (according to RECIST v1.1) within 12 weeks of the last dose of a PD-1 blocking antibody, either as monotherapy or in combination with other agents.

    Evidence of confirmed PD must be established by investigator assessment at least 4 weeks after the initial date of PD. The second assessment may serve as the Baseline for this study if completed within 30 days before to the start of study treatment. NOTE: in subjects with histologically confirmed recurrence on or after adjuvant PD-1 blocking antibody, confirmatory imaging is not required.

    c. Documented disease progression in any lesion that was previously radiated in order to serve as a target lesion.

  5. Able to provide tissue from a core or excisional biopsy (fine needle aspirate is not sufficient). A fresh tissue biopsy (within 90 days before the start of study treatment) is preferred but an archival sample is acceptable if no intervening therapy was received.
  6. For tissue sampling details, please refer to the laboratory manual.
