Abstract

The present disclosure relates to the identification and use of biomarkers (e.g., analytes, analyte profiles, or markers (e.g., gene expression and/or protein expression profiles)) with clinical relevance to cytokine release syndrome (CRS).

First claim

What is claimed is:

1. A method for treating a subject having a cancer, comprising:
administering to the subject a therapeutically effective dose of a CAR-expressing cell therapy, and
measuring the level or activity of soluble gp130 (sgp130) in a sample from the subject to determine a cytokine release syndrome (CRS) risk status comprising a measure of the level or activity of sgp130, wherein the CRS risk status is indicative of the subject's risk for developing CRS, wherein the subject is identified as being at risk of developing CRS if the level or activity of sgp130 is greater than a reference level or activity; and
responsive to a determination of the CRS risk status,
administering to the subject a second therapy comprising one or more of: an IL6 inhibitor, a vasoactive medication, an immunosuppressive agent, a corticosteroid, or mechanical ventilation if the level or activity of sgp130 is greater than the reference level or activity.

2. The method of claim 1 , wherein said CRS risk status further comprises a measure of the level or activity of IL6 receptor (IL6R) or soluble IL6 receptor (sIL6R).

3. The method of claim 1 , wherein:
(i) the CRS risk status is indicative of whether the subject is at high risk or low risk of developing severe CRS;
(ii) the CRS is of clinical grade 1-5;
(iii) the CRS is severe CRS; or
(iv) the CRS is severe CRS of clinical grade 4-5.

4. The method of claim 3 , wherein said measure of CRS risk status further comprises a measure of one, two, three, four, five, six, seven, eight, nine, ten, or all of the following:
(i) the level or activity of sgp130 or interferon-gamma (IFN-g), or a combination thereof;
(ii) the level or activity of sgp130, IFN-gamma, or IL1Ra, or a combination thereof;
(iii) the level or activity of sgp130, IFN-gamma, or MIP1-alpha, or a combination thereof;
(iv) the level or activity of sgp130, MCP1, or eotaxin, or a combination thereof;
(v) the level or activity of IL2, eotaxin, or sgp130, or a combination thereof;
(vi) the level or activity of IFN-gamma, IL2, or eotaxin, or a combination thereof;
(vii) the level or activity of IL10, or the level of disease burden in the subject, or a combination thereof;
(viii) the level or activity of IFN-gamma or IL-13, or a combination thereof;
(ix) the level or activity of IFN-gamma, IL-13, or MIP1-alpha, or a combination thereof;
(x) the level or activity of IFN-gamma or MIP1-alpha, or a combination thereof;
(xi) the level or activity of IFN-gamma, IL6, sIL6R or sgp130, or a combination thereof.

5. The method of claim 4 , wherein the subject at high risk of severe CRS is identified as having:
a greater level or activity of sgp130 and a greater level or activity of IFN-gamma;
a greater level or activity of sgp130 and a lower level or activity of IL1Ra;
a greater level or activity of IFN-gamma and a lower level or activity of IL1Ra;
a greater level or activity of sgp130, a greater level or activity of IFN-gamma, and a lower level or activity of IL1Ra;
a greater level or activity of sgp130 and bone marrow disease;
a greater level or activity of IFN gamma and bone marrow disease; or
a greater level or activity of sgp130, IFN gamma and bone marrow disease,
compared to a reference sample from a subject at low risk of severe CRS or a control level or activity.

6. The method of claim 4 , wherein the subject at high risk of severe CRS is identified as having:
a greater level or activity of sgp130 and a lower level or activity of MIP1-alpha;
a greater level or activity of IFN-gamma and a lower level or activity of M1P1-alpha;
a greater level or activity of sgp130, a greater level or activity of IFN-gamma, and a lower level or activity of MIP1-alpha;
a greater level or activity of sgp130 and a greater level or activity of MCP1;
a greater level or activity of sgp130 and a lower level or activity of eotaxin;
a greater level or activity of MCP1 and a lower level or activity of eotaxin; or
a greater level or activity of sgp130, a greater level or activity of MCP1, and a lower level or activity of eotaxin;
compared to a reference sample from a subject at low risk of severe CRS or compared to a control level or activity.

7. The method of claim 4 , wherein the subject at high risk of severe CRS is identified as having:
a greater level or activity of IL-2 and a lower level or activity of eotaxin;
a greater level or activity of IL-2 and a greater level or activity of sgp130;
a lower level or activity of eotaxin and a greater level or activity of sgp130;
a greater level or activity of IL-2, a lower level or activity of eotaxin, and a greater level or activity of sgp130;
a greater level or activity of IFN-gamma and a greater level or activity of IL-2;
a greater level or activity of IFN-gamma and a lower level or activity of eotaxin; or
a greater level or activity of IFN-gamma, a greater level or activity of IL-2, and a lower level or activity of eotaxin,
compared to a reference sample from a subject at low risk of severe CRS or compared to a control level or activity.

8. The method of claim 3 , further comprising the step of selecting a CAR-expressing cell therapy for the subject, based on the CRS risk status acquired, wherein:
(i) the CRS risk status acquired is that the subject is at high risk of severe CRS, and the therapy suggested is a subsequent dose of CAR-expressing cells that is at a lower dose than the previous dose of CAR-expressing cell therapy administered to the subject; or
(ii) the CRS risk status acquired is that the subject is at high risk of severe CRS, and the therapy suggested is a subsequent dose of CAR-expressing cells that comprises a different CAR or different cell type than the previous CAR-expressing cell therapy administered to the subject.

9. The method of claim 1 wherein the method is performed on a subject that does not have:
(i) a symptom of CRS;
(ii) a symptom of severe CRS;
(iii) low blood pressure or a fever; or
(iv) grade 4 organ toxicity or a need for mechanical ventilation.

10. The method of claim 1 , wherein the reference level or activity is from a subject at low risk of severe CRS or a healthy subject.

11. The method of claim 1 , wherein said CRS risk status further comprises a measure of the level or activity of IL6.

12. The method of claim 11 , wherein the level or activity of IL6 and/or sgp130 is at least 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 40, 50, 100, 500, 1000-fold or more greater, relative to the reference level or activity.

13. The method of claim 1 , wherein the measure of sgp130 evaluates the mRNA level or protein level.

14. The method of claim 1 , further comprising acquiring a measure of the level or activity of one, two, three, four, five, ten, twenty or more of a cytokine or cytokine receptor chosen from sTNFR2, IP10, sIL1R2, sTNFR1, M1G, VEGF, sILR1, TNFα, IFNα, GCSF, sRAGE, IL4, IL10, IL1R1, IFN-γ, IL8, sIL2Ra, sgp130, MCP1, MIP1α, M1β, or GM-CSF, or a combination thereof.
