Detailed Summary

This pilot phase II trial studies how well pembrolizumab works in treating patients with desmoplastic melanoma (DM) that can be removed by surgery (resectable) or cannot be removed by surgery (unresectable). Immunotherapy with monoclonal antibodies, such as pembrolizumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread.

Arms & Interventions

Cohort A (pembrolizumab, surgery)experimental

Patients receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 3 cycles. Patients with potentially resectable disease undergo surgery. Patients with tumor progression and unresectable disease may receive one additional cycle of pembrolizumab. Patients undergo CT scan and may undergo PET and MRI throughout the study. Patients also undergo blood sample collection at screening and tumor biopsy throughout the study.

Cohort B (pembrolizumab)experimental

Patients with unresectable disease receive pembrolizumab IV over 30 minutes on day 1. Treatment repeats every 21 days for up to 34 cycles in the absence of disease progression or toxicity. Patients undergo CT scan and may undergo PET and MRI throughout the study. Patients also undergo blood sample collection at screening and tumor biopsy throughout the study.
