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 hGMCSF 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 hGMCSF antagonist for use in methods of inhibiting or reducing the incidence or the severity of immunotherapy-related toxicity in a subject also are provided.

Method of increasing the efficacy of CAR-T immunotherapy using lenzilumab

Methods for reducing blood-brain barrier disruption in a subject treated with immunotherapy, the method comprising administering a recombinant GM-CSF antagonist to the subject. Methods for preserving blood-brain barrier integrity in a subject treated with immunotherapy, the method comprising administering a recombinant hGM-CSF antagonist to the subject. Methods for decreasing or preventing CAR-T cell therapy-induced neuroinflammation in a subject in need thereof, the method comprising administering a recombinant GM-CSF antagonist to the subject. Methods for preventing or reducing blood-brain barrier disruption in a subject treated with immunotherapy, the method comprising administering CAR-T cells having a GM-CSF gene knockout (GM-CSFCAR-T cells) to the subject.

Methods of treating CART-T cell therapy-induced neuroinflammation using a GM-CSF antagonist

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-CSFCAR-T cells), and a recombinant hGM-CSF antagonist.

Method of reducing tumor relapse rate in immunotherapy by administration of lenzilumab

Method of reducing the level of non-GM-CSF cytokines/chemokines in immunotherapy-related toxicity

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.
