Study Summary
This phase II trial investigates how well biomarkers on PET/CT imaging drive early discontinuation of anti-PD-1 therapy in patients with stage IIIB-IV melanoma that cannot be removed by surgery (unresectable). Anti-PD-1 therapy has become a standard therapy option for patients with unresectable melanoma. This trial is being done to determine if doctors can safely shorten the use of standard of care anti-PD1 therapy for melanoma by using biomarkers seen on PET/CT imaging and tumor biopsy.
Primary Outcome
Event is defined as recurrence, progression or melanoma-specific death. The distribution of EFS will be evaluated using the method of Kaplan-Meier.
