TL;DR: In this paper, the authors provide clarification and correction to their article "Genetic Basis for Clinical Response to CTLA-4 Blockade in Melanoma" (Dec. 4, 2014, issue).
Journal ArticleDOI
Genomic and transcriptomic features of response to anti-pd-1 therapy in metastatic melanoma
Willy Hugo,Jesse M. Zaretsky,Lu Sun,Chunying Song,Blanca Homet Moreno,Siwen Hu-Lieskovan,Beata Berent-Maoz,Jia Pang,Bartosz Chmielowski,Grace Cherry,Elizabeth Seja,Shirley H. Lomeli,Xiangju Kong,Mark C. Kelley,Jeffrey A. Sosman,Douglas B. Johnson,Antoni Ribas,Roger S. Lo +17 more
TL;DR: It is found that overall high mutational loads associate with improved survival, and tumors from responding patients are enriched for mutations in the DNA repair gene BRCA2, suggesting that attenuating the biological processes that underlie IPRES may improve anti-PD-1 response in melanoma and other cancer types.
Journal ArticleDOI

TL;DR: Acquired resistance to PD-1 blockade immunotherapy in patients with melanoma was associated with defects in the pathways involved in interferon-receptor signaling and in antigen presentation.
Journal ArticleDOI
Interferon Receptor Signaling Pathways Regulating PD-L1 and PD-L2 Expression.

Lo,Antoni Ribas +18 more
TL;DR: Analysis of biopsy specimens from patients with melanoma confirmed interferon signature enrichment and upregulation of gene targets for STAT1/STAT2/STAT3 and IRF1 in anti-PD-1-responding tumors.
Journal ArticleDOI
Primary Resistance to PD-1 Blockade Mediated by JAK1/2 Mutations.
Daniel Sanghoon Shin,Jesse M. Zaretsky,Helena Escuin-Ordinas,Angel Garcia-Diaz,Siwen Hu-Lieskovan,Anusha Kalbasi,Catherine S. Grasso,Willy Hugo,Salemiz Sandoval,Davis Y. Torrejon,Nicolaos Palaskas,Gabriel Abril Rodriguez,Giulia Parisi,Ariel M. Azhdam,Bartosz Chmielowski,Grace Cherry,Elizabeth Seja,Beata Berent-Maoz,I. Peter Shintaku,Dung Thi Le,Drew M. Pardoll,Luis A. Diaz,Paul C. Tumeh,Thomas G. Graeber,Roger S. Lo,Begoña Comin-Anduix,Antoni Ribas +26 more
TL;DR: It is proposed that JAK1/2 loss-of-function mutations are a genetic mechanism of lack of reactive PD-L1 expression and response to interferon gamma, leading to primary resistance to PD-1 blockade therapy.
