    Nuclear IRF-1 expression as a mechanism to assess “Capability” to express PD-L1 and response to PD-1 therapy in metastatic melanoma by Mario Sznol, Harriet M. Kluger, Pok Fai Wong, James W. Smithy, David L. Rimm, Vasiliki Pelekanou, Lauren M. Moore, Jamaal Rehman, Patricia Gaule, Veronique M. Neumeister

    Published 2017-12-01
    “…Specifically, response is seen in tumors that do not express programmed death ligand 1 (PD-L1), highlighting the need for a more sensitive biomarker. We hypothesize that capacity to express PD-L1, as assessed by an assay for a PD-L1 transcription factor, interferon regulatory factor 1 (IRF-1), may better distinguish patients likely to benefit from anti-PD-1 immunotherapy.Methods Samples from 47 melanoma patients that received nivolumab, pembrolizumab, or combination ipilimumab/nivolumab at Yale New Haven Hospital from May 2013 to March 2016 were collected. …”
