Abstract

Summ a r yImmune checkpoint inhibitors have improved clinical outcomes associated with numerous cancers, but high-grade, immune-related adverse events can occur, particularly with combination immunotherapy.We report the cases of two patients with melanoma in whom fatal myocarditis developed after treatment with ipilimumab and nivolumab.In both patients, there was development of myositis with rhabdomyolysis, early progressive and refractory cardiac electrical instability, and myocarditis with a robust presence of T-cell and macrophage infiltrates.Selective clonal T-cell populations infiltrating the myocardium were identical to those present in tumors and skeletal muscle.Pharmacovigilance studies show that myocarditis occurred in 0.27% of patients treated with a combination of ipilimumab and nivolumab, which suggests that our patients were having a rare, potentially fatal, T-cell-driven drug reaction.(Funded by Vanderbilt-Ingram Cancer Center Ambassadors and others.)I mmune checkpoint inhibitors have transformed the treatment of several cancers by releasing restrained antitumor immune responses.1 Ipilimumab, an anti-cytotoxic T-lymphocyte-associated antigen 4 (CTLA-4) antibody, and nivolumab, an anti-programmed death-1 (PD-1) antibody, have individually improved survival in patients with melanoma, and early results suggest that their combination further enhances antitumor activity and survival.[2][3][4][5] Other adverse events associated with these agents include dermatitis, endocrinopathies, colitis, hepatitis, and pneumonitis, which are all thought to arise from aberrant activation of autoreactive T cells.6,7 These toxic effects are more frequent and severe when ipilimumab and nivolumab are used in combination.4 Here, we report two cases of lethal myocarditis accompanied by myositis in patients treated with a combination of nivolumab and ipilimumab.

  • Following ICI therapy, 40% of patients with myocarditis experience concomitant myositis, confirmed in mouse models.

    “Following ICI therapy, 40% of patients with myocarditis experience concomitant myositis, confirmed in mouse models. 41,42,46,68,282”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [46]

    The Introduction and Results report two patients who developed both myocarditis and myositis after combination immune checkpoint therapy. They do not establish that this occurs in 40% of patients with myocarditis. The Discussion cites mouse models for mechanisms of myocarditis, not confirmation of the claimed co-occurrence rate. Page numbers are unavailable in our copy. (LLM, conf=0.88)

  • T cells targeting both heart and tumor antigens are involved in ICI myocarditis development.

    “indicating the involvement of T cells targeting both heart and tumor antigens in myocarditis development.”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [46]

    The Results report shared, expanded T-cell receptor sequences in heart and tumor tissue from two patients with checkpoint-inhibitor myocarditis. The Discussion presents T cells targeting shared or cross-reactive antigens as possible mechanisms, but also says the shared sequences could have different antigen specificities. It does not establish that the T cells targeted both heart and tumor antigens. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • The discovery of α-MyHC-specific T cells in ICI myocarditis suggests potential involvement of autoreactive T cells targeting α-MyHC in the initiation and progression of other forms of myocarditis.

    “This discovery suggests a potential involvement of autoreactive T cells targeting α -MyHC in the initiation and progression of other forms of myocarditis.”

    From Autoimmune Myocarditis, Old Dogs and New Tricks. (2024) · cites this paper as [46]

    The Results report T-cell infiltration and shared T-cell receptor sequences in the hearts, skeletal muscle, and tumors of two patients with ICI myocarditis. The Discussion suggests that understanding this toxicity may offer insight into idiopathic myocarditis, but says the antigens recognized by those T cells remain unidentified. It does not report a discovery of α-MyHC-specific T cells or implicate that antigen in other forms of myocarditis; page numbers were not available in our copy. (LLM, conf=0.88)

  • Recent cases of ICI myocarditis have expanded insights into the role of α-MyHC-specific T cells in myocarditis development.

    The Results report T-cell infiltration and shared T-cell receptor sequences in the myocardium, skeletal muscle, and tumors of two patients with ICI myocarditis. But the Discussion says the antigens recognized by those T cells remain unidentified; our copy does not establish that they were α-MyHC-specific. (LLM, conf=0.88)

    From irAE-GPT: leveraging large language models to identify immune-related adverse events in electronic health records and clinical trial datasets (2026) · cites this paper as [5]

    The Introduction (page unavailable) lists colitis, hepatitis, pneumonitis, dermatitis, and endocrinopathies as side effects, and reports two cases of myocarditis, supporting the colon, liver, lungs, skin, endocrine system, and heart portions of the claim. The supplied passages and a search for neurological adverse events do not support the nervous-system portion. (LLM, conf=0.88)

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.
