Abstract
Methods for reducing relapse rate or preventing occurrence of tumor relapse in a subject treated with immunotherapy, in an absence of an incidence of immunotherapy-related toxicity or in a presence of immunotherapy-related toxicity. Methods for reducing a level of a cytokine or chemokine other than GM-CSF in a subject having an incidence of immunotherapy-related toxicity, the methods comprising administering a recombinant GM-CSF antagonist to the subject. Methods for treating or preventing immunotherapy-related toxicity in a subject, the methods comprising administering to the subject chimeric antigen receptor-expressing T-cells (CAR-T cells), the CAR-T cells having a GM-CSF gene knockout (GM-CSFk/o CAR-T cells), and a recombinant hGM-CSF antagonist.
