## Abstract

Materials and methods for identifying subjects as being likely or not likely to respond to an interleukin-1β receptor antagonist (IL-1RA) therapy for a seizure disorder, as well as materials and methods for treating subjects identified as being likely to respond to an IL-1RA therapy for a seizure disorder, are provided herein.

## Claims

### Claim 1

A method for treating a subject having a seizure disorder, said method comprising determining that the subject has decreased IL-1RA function as compared to the level of IL-1RA function in corresponding normal subjects who do not have the seizure disorder, and administering to the subject a treatment that attenuates IL-1R inflammatory signaling, wherein said treatment comprises one or more of anakinra, EBI-005, and MEDI-8968.

### Claim 2 (depends on 1)

The method of claim 1, wherein the treatment comprises anakinra.

### Claim 3 (depends on 1)

The method of claim 1, wherein the seizure disorder is FIRES, PASS, DIRA, or MRE.

### Claim 4 (depends on 1)

The method of claim 1, wherein the subject is a human child.

### Claim 5 (depends on 1)

The method of claim 1, wherein the determining comprises measuring IL-1RA activity in a biological sample from the subject, wherein the biological sample comprises serum, serum microvesicles, or CSF, and determining that the IL-1RA activity in the biological sample is decreased relative to a corresponding control level of IL-1RA activity.

### Claim 6 (depends on 1)

The method of claim 1, wherein the determining comprises measuring an inflammatory response in primed and stimulated neutrophils, monocytes, or PBMCs isolated from the subject, and determining that the measured inflammatory response is higher than an inflammatory response for control primed and stimulated neutrophils, monocytes, or PBMCs from subjects who do not have the seizure disorder.

### Claim 7 (depends on 6)

The method of claim 6, comprising determining that the measured inflammatory response is at least two standard deviations higher than the inflammatory response for control primed and stimulated neutrophils, monocytes, or PBMCs from subjects who do not have the seizure disorder.

### Claim 8 (depends on 6)

The method of claim 6, wherein the inflammatory response comprises secretion of IL-1β, IL-1RA, IL-18, IL-33, IL-36, IL-37, or IL-38 from the neutrophils, monocytes, or PBMCs after stimulation.

### Claim 9 (depends on 6)

The method of claim 6, comprising priming the neutrophils, monocytes, or PBMCs with LPS.

### Claim 10 (depends on 6)

The method of claim 6, comprising stimulating the neutrophils, monocytes, or PBMCs with ATP.

### Claim 11 (depends on 1)

The method of claim 1, wherein the determining comprises measuring the relative amounts of IL-1RA (protein) or IL1RN (mRNA) isoforms in a biological sample from the subject, and determining that the subject has a ratio of soluble IL-1RA: intracellular IL-1RA that is increased relative to a control ratio of soluble IL-1RA: intracellular IL-1RA.

### Claim 12 (depends on 11)

The method of claim 11, wherein the control ratio of soluble IL-1RA: intracellular IL-1RA is the ratio of soluble IL-1RA: intracellular IL-1RA in control subjects not having the seizure disorder.

### Claim 13

A method for treating a subject having a seizure disorder, comprising identifying the subject as having a level of functional IL-1RA antagonism that is decreased below a predetermined threshold level of functional IL-1RA antagonism, and administering to the subject a treatment that attenuates IL-1R inflammatory signaling, wherein said treatment is selected from the group consisting of anakinra, EBI-005, and MEDI-8968.

### Claim 14 (depends on 13)

The method of claim 13, wherein the treatment comprises anakinra.

### Claim 15 (depends on 13)

The method of claim 13, wherein the seizure disorder is FIRES, PASS, DIRA, or MRE.

### Claim 16 (depends on 13)

The method of claim 13, wherein the subject is a human child.

### Claim 17 (depends on 13)

The method of claim 13, wherein the threshold level is 10% of the level of functional IL-1RA antagonism in corresponding control subjects who do not have the seizure disorder.
