Cryoablation+Ipilimumab+Nivolumab in Melanoma

Adult patients (age > 18) with unresectable melanoma who have progressed on immune checkpoint inhibitor therapy (pembrolizumab, nivolumab, nivolumab-relatimab, atezolizumab, ipilimumab) and for whom their treating physician plans to initiate dual ICI with ipilimumab and nivolumab. Progression on adjuvant PD-1 inhibition is permitted. PD-1 does not have to be the last therapy received. This is no limited on prior lines of ICI received. There is no wash-out period required from the time of their last therapy.

Patients are medically eligible for dual checkpoint inhibition (i.e. no untreated/uncontrolled intercurrent medical issue including ongoing immune-related adverse event or need for systemic steroids >10mg PO prednisone or its equivalent, ECOG PS ≤2) with ipilimumab 3mg/kg and nivolumab 1mg/kg by their treating physician

Must have a tumor amenable to percutaneous image-guided cryoablation based on routine Interventional Radiology criteria.

Patients must have measurable disease (by RECIST) independent of the lesion to be ablated. Measurable disease is defined as at least one lesion that can be accurately measured in at least one dimension (longest diameter to be recorded for non-nodal lesions and short axis for nodal lesions) as ≥20 mm with conventional techniques or as ≥10 mm with spiral CT scan, MRI, or calipers by clinical exam. See Section 11 (Measurement of Effect) for evaluation of measurable disease.
