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.

Abstract: Methods of inhibiting or reducing the incidence or the severity of immunotherapy-related toxicity in a subject, the method comprising a step of administering a recombinant hGM-CSF antagonist to the subject, wherein said administering inhibits or reduces the incidence or the severity of immunotherapy-related toxicity in said subject, are provided. An hGM-CSF antagonist for use in methods of inhibiting or reducing the incidence or the severity of immunotherapy-related toxicity in a subject also are provided.

Abstract: This invention concerns a dosage form comprising a therapeutically effective amount of A19-144 or A2-73 and a therapeutically effective amount of at least one AED. This invention further encompasses a method of treating a subject in need of such treatment comprising administering a therapeutically effective amount of A19-144 or A2-73 in conjunction with an therapeutically effective amount of an AED.
