Abstract

BACKGROUND: Approximately 75% of objective responses to anti-programmed death 1 (PD-1) therapy in patients with melanoma are durable, lasting for years, but delayed relapses have been noted long after initial objective tumor regression despite continuous therapy. Mechanisms of immune escape in this context are unknown. METHODS: We analyzed biopsy samples from paired baseline and relapsing lesions in four patients with metastatic melanoma who had had an initial objective tumor regression in response to anti-PD-1 therapy (pembrolizumab) followed by disease progression months to years later. RESULTS: Whole-exome sequencing detected clonal selection and outgrowth of the acquired resistant tumors and, in two of the four patients, revealed resistance-associated loss-of-function mutations in the genes encoding interferon-receptor-associated Janus kinase 1 (JAK1) or Janus kinase 2 (JAK2), concurrent with deletion of the wild-type allele. A truncating mutation in the gene encoding the antigen-presenting protein beta-2-microglobulin (B2M) was identified in a third patient. JAK1 and JAK2 truncating mutations resulted in a lack of response to interferon gamma, including insensitivity to its antiproliferative effects on cancer cells. The B2M truncating mutation led to loss of surface expression of major histocompatibility complex class I. CONCLUSIONS: In this study, 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.

  • Clinically relevant ICR mechanisms include B2M mutations causing MHC Class I loss, antigen presentation downregulation, and IFNγ-JAK/STAT mutations that impair response to T cell anti-tumor activity.

    “Clinically relevant mechanisms of include mutations in beta-2-microglobulin (B2M) resulting in loss of MHC Class I presentation, downregulation of the antigen presentation machinery, and mutations in the IFNγ-JAK/STAT pathway that impair response to T cell mediated anti-tumor activity7–9.”
  • Perturbations of B2M, HLA-A, JAK1, JAK2, STAT1, IFNGR1, and IFNGR2 conferred immune evasion, consistent with clinical resistance mechanisms.

    “perturbations of B2M, HLA-A, JAK1, JAK2, STAT1, IFNGR1 and IFNGR2 (Fig. 2d,e, Extended Data Fig. 3e,f, Supplementary Table 2) conferred immune evasion, consistent with clinical mechanisms of resistance to immunotherapy7–9.”
  • These findings are consistent with clinical data correlating resistance to checkpoint inhibitors with mutations in B2m and IFNγ pathways and with recent genome-wide CRISPR screening data.

    “These findings are consistent with emerging clinical data correlating resistance to checkpoint inhibitors with mutations in the B2m and IFNγ pathways (Gao et al., 2016; Zaretsky et al., 2016), and with recent genome-wide CRISPR screening data (Patel et al., 2017).”

  • Mutations in IFNGR1 and JAK, part of IFNγ signaling, have been found in patients who developed resistance to checkpoint inhibitors.

    “Mutations in IFNGR1 and JAK, a component of the IFNγ signaling pathway, have been found in patients presenting resistance to checkpoint inhibitors (Gao et al., 2016; Zaretsky et al., 2016).”

  • Tumor cells may evade immune recognition by downregulating tumor antigens or MHC class I.

    “Tumor cells may evade immune recognition directly by downregulating features that make them vulnerable such as tumor antigens or MHC class I (4–6).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
