Abstract

Provided are methods, kits and compositions related to toxicity associated with administration of cell therapy for the treatment of diseases or conditions, e.g., cancer, including methods for use in predicting and treating a toxicity. In some embodiments, the toxicity is a neurotoxicity or cytokine release syndrome (CRS), such as a severe neurotoxicity or a severe CRS. The methods generally involve detecting a parameter of a biomarker or individually a parameter of each biomarker in a panel of biomarkers, such as a concentration, amount or activity, and comparing the detected parameter to a reference value for the parameter to determine if the subject is at risk for developing the toxicity, such as neurotoxicity or CRS or severe neurotoxicity or severe CRS. In some embodiments, the methods further involve administering an agent or therapy for treating, ameliorating, preventing, delaying and/or attenuating the development of the toxicity, such as neurotoxicity or CRS, such as severe neurotoxicity or severe CRS.

First claim

The invention claimed is:

1. A method of ameliorating the development of toxicity in a subject, the method comprising administering an agent or therapy that is capable of treating, preventing, delaying, or attenuating the development of a toxicity to a subject, wherein the agent or therapy is a corticosteroid or is an anti-IL-6 receptor (anti-IL-6R) antibody or antigen-binding fragment thereof; and wherein the subject is determined to be at risk of developing the toxicity by a method comprising:
(a) detecting a concentration or relative concentration for a biomarker or, individually, for each biomarker in a panel of biomarkers in a biological sample, wherein:
the biomarker or one or more of the biomarkers in the panel of biomarkers, individually, is or comprises a cytokine selected from among transforming growth factor beta (TGF-beta), interleukin 6 (IL-6), interleukin 10 (IL-10), interleukin 15 (IL-15), interferon gamma (IFN-gamma) and monocyte chemoattractant protein-1 (MCP-1); and
the biological sample is obtained or has been obtained from the subject no more than 14 days after administration of a cell therapy comprising a dose of T cells expressing a chimeric antigen receptor (CAR) for treating a disease or condition in the subject, wherein the disease or condition is a non-Hodgkin lymphoma (NHL) or acute lymphoblastic leukemia (ALL) or chronic lymphocytic leukemia (CLL); and

(b) comparing the concentration or relative concentration detected for the biomarker, or for each of the biomarkers in the panel, individually, to a reference value, wherein the subject is one in which the comparison indicates that the subject is at risk of developing the toxicity, wherein the toxicity is severe neurotoxicity and/or is a grade 3 or higher neurotoxicity.

2. The method of claim 1 , wherein the biological sample is obtained or has been obtained from the subject no more than 3 days, no more than 2 days, or no more than 1 day after administration of a cell therapy for treating a disease or condition in the subject.

3. The method of claim 1 , wherein the method comprises detecting a concentration or relative concentration of each biomarker in a panel of biomarkers, wherein the panel of biomarkers comprises at least TGF-β and IL-6.

4. The method of claim 1 , wherein the biological sample is derived from the subject at a time at which the subject does or did not exhibit a physical sign or symptom of neurotoxicity or cytokine release syndrome (CRS).

5. The method of claim 1 , wherein the method comprises detecting a concentration or relative concentration of each biomarker in a panel of biomarkers, wherein the panel of biomarkers comprises at least IL-15 and IL-6.

6. The method of claim 1 , wherein the biomarker or panel of biomarkers comprises IL-6.

7. The method of claim 4 , wherein neurotoxicity a severe neurotoxicity.

8. The method of claim 1 , wherein the biomarker or panel of biomarkers comprise one or a combination of cytokines comprising at least one cytokine selected from among TGF-beta, IL-6 and IL-15 and the comparison indicates that the subject is at risk for developing the toxicity if the detected concentration or relative concentration for at least one of the cytokines meets a classification selected from: (i) for TGF-beta, less than a TGF-beta reference value; (ii) for IL-6, greater than a IL-6 reference value; and/or (iii) for IL-15, greater than a IL-15 reference value.

9. The method of claim 8 , wherein the biomarker or panel of biomarkers comprise a first and second cytokine selected from among: TGF-beta and IL-6, TGF-beta and IL-15, or IL-6 and IL-15, and the comparison indicates that the subject is at risk for developing the toxicity
if the detected concentration or relative concentration for each of the first and second cytokines, individually, meets the classification.

10. The method of claim 8 , wherein a concentration or relative concentration of each of TGF-beta, IL-6 and IL-15 are detected, and wherein:
if the detected concentration or relative concentration for all three cytokines meet the classification, then the comparison indicates the subject is at risk for the toxicity; or
if the detected concentration or relative concentration for at least two of the cytokines meet the classification, then the comparison indicates the subject is at risk for the toxicity.

11. The method of claim 8 , wherein:
the TGF-beta reference value is within a range from 5.5 pg/mL to 15.00 pg/mL (log 2 scale) or from 45 pg/mL to 33000 pg/mL;
the IL-6 reference value is within a range from 2.6 pg/mL to 5.4 pg/mL (log 2 scale) or from 6.00 pg/mL to 41.0 pg/mL; and/or
the IL-15 reference value is within a range from 6.1 pg/mL to 7.1 pg/mL (log 2 scale) or from 69.0 pg/mL to 135.0 pg/mL.

12. The method of claim 8 , wherein the disease or condition in the subject is a non-Hodgkin lymphoma (NHL).

13. The method of claim 1 , wherein the biomarker or panel of biomarkers comprise one or a combination of cytokines comprising at least one cytokine selected from among MCP-1, IL-6 and IL15, and the comparison indicates that the subject is at risk for developing the toxicity, if the detected concentration or relative concentration for at least one of the cytokines meets a classification selected from: (i) for MCP-1, greater than a MCP-1 reference value; (ii) for IL-6, greater than a IL-6 reference value; and/or (iii) for IL-15, greater than a IL-15 reference value.

14. The method of claim 13 , wherein
if the detected concentration or relative concentration for at least two of the cytokines or all three cytokines meet the classification, the comparison indicates the subject is at risk of the toxicity.

15. The method of claim 14 , wherein:
the IL-6 reference value is within a range, or is a range, from 2.0 pg/mL to 4.0 pg/mL (log 2 scale) or from 6.00 pg/mL to 12.0 pg/mL; and/or
the IL-15 reference value is within a range, or is a range, from 5.0 pg/mL to 6.5 pg/mL (log 2 scale) or from 40.0 pg/mL to 90.0 pg/mL; and/or
the MCP-1 reference value is within a range, or is a range, from 7.00 pg/mL to 12.0 pg/mL (log 2 scale) or from 700 pg/mL to 1400 pg/mL.

16. The method of claim 13 , wherein the disease or condition in the subject is acute lymphoblastic leukemia (ALL).

17. The method of claim 8 , further comprising:
detecting a concentration or relative concentration for IL-10 or IFN-gamma in a sample from the subject, wherein the biological sample is or has been derived from the subject no more than three days after the administration of the cells; and
