Publication number: 20210171631Abstract: The present invention relates to the identification of fibrinogen like protein 1 (FGL1) as a prognostic biomarker for responsiveness to an immune checkpoint inhibitor in a cancer patient. More specifically it relates to methods of treating cancer in a human patient comprising administering an immune checkpoint inhibitory antibody specifically inhibiting the interaction of fibrinogen-like protein 1 (FGL1) with lymphocyte-activation gene 3 protein (LAG3), wherein the cancer is an FGL1 expressing cancer. Further, the invention relates to methods for assessing susceptibility or predicting the responsiveness to the treatment with an immune checkpoint inhibitory antibody specifically inhibiting the interaction of FGL1 with LAG3 in a cancer patient, comprising detecting FGL1 expression in a sample from said patient and to a kit for selecting a cancer patient that would benefit from an immune checkpoint inhibitory antibody specifically inhibiting the interaction of FGL1 with LAG3.Type: ApplicationFiled: June 10, 2019Publication date: June 10, 2021Inventors: Lieping CHEN, Jun WANG, David A.
