Title:
Transcriptomic and immunophenotypic profiles of melanoma tissue from patients (pts) treated with anti-PD-1 +/- ipilimumab to define mechanisms of response and resistance.
Published date:

Excerpt:
141 melanoma biopsies from advanced melanoma pts treated with anti-PD-1 monotherapy (n= 54), or anti-PD1 + ipilimumab (n= 51) were classified as responders (CR/PR/SD > 6 mo) or non-responders (SD≤6 mo/PD) based on RECIST....Responders to monotherapy displayed increased expression of genes associated with a Type 1 interferon response, tissue-resident T-cells and drug targets (TIGIT, ADAR, ADORA2A, CD137, IDO1 and LAG3) (diff. p < 0.05).
