Abstract

Claims (19)

1. A method of treating a patient group in need of an anti-cancer treatment comprising administering to a patient within the patient group an effective amount of an anti-PD-1 antibody or antigen-binding portion thereof (“anti-PD-1 antibody”) or an effective amount of an anti-PD-L1 antibody or antigen-binding portion thereof (“anti-PD-L1 antibody”);

wherein the patient has been identified as having a cytokine score that is higher than an average cytokine score;

wherein the cytokine score is the sum of a point designated to the level of at least two cytokines in a sample obtained from the patient, wherein the point is 2 if the sample has a high concentration of a cytokine that is positively associated with overall survival of the patient following the administration of the anti-PD-1 antibody or the anti-PD-L1 antibody or a low concentration of a cytokine that is negatively associated with overall survival of the patient following the administration of the anti-PD-1 antibody or the anti-PD-L1 antibody, wherein the point is 0 if the sample has a low concentration of a cytokine that is positively associated with the overall survival of the patient following the administration of the anti-PD-1 antibody or the anti-PD-L1 antibody or a high concentration of a cytokine that is negatively associated with the overall survival of the patient following the administration of the anti-PD-1 antibody or the anti-PD-L1 antibody, and wherein the point is 1 if the sample has a medium concentration of a cytokine that is either negatively or positively associated with overall survival of the patient following the administration of the anti-PD-1 antibody or the anti-PD-L1 antibody;

wherein the positively associated cytokines comprise one or more of MIG, IL-1RA, and MMP-3;

wherein the negatively associated cytokines comprise one or more of IL-8, FRTN, ICAM, VWF, MICA, IP-10, CRP, IL-18, IL-6, and MIP1B;

wherein a high cytokine score is determined by measuring the expression of the cytokine in a sample obtained from each patient of the patient group prior to administering the anti-PD-1 antibody or the anti-PD-L1 antibody and dividing the sum of the individual cytokine expressions by the number of patients to obtain a median, wherein an expression level that is at least 1% higher than the median is characterized as a high cytokine score;

wherein an expression that is at least 1% lower than the median is characterized as a low cytokine score; and

wherein the average cytokine score is determined by measuring a cytokine score from a sample obtained from each patient of the patient group prior to administering the anti-PD-1 antibody or the anti-PD-L1 antibody and dividing the sum of the individual cytokine scores by the number of patients.

2. The method of claim 1 , further comprising measuring the cytokine score from the sample obtained from the patient prior to administering the anti-PD-1 antibody or the anti-PD-L1 antibody.

3. The method of claim 2 , wherein the cytokine score is at least about 1% higher than the average cytokine score.

4. The method of claim 1 , wherein the average cytokine score is any integer between 1 and 100.

5. The method of claim 1 , wherein the at least two cytokines comprise three cytokines.

6. The method of claim 1 , wherein the patient has lung cancer.

7. The method of claim 6 , wherein the lung cancer is non-small cell lung cancer.

8. The method of claim 1 , wherein the anti-PD-1 antibody is nivolumab.

9. The method of claim 1 , wherein the anti-PD-L1 antibody is selected from BMS-936559, MPDL3280A, MEDI4736, and MSB0010718C.

10. The method of claim 1 , wherein the anti-PD-1 antibody is pembrolizumab.

11. The method of claim 1 , wherein the at least two cytokines comprise four cytokines.

12. The method of claim 1 , wherein the at least two cytokines comprise five cytokines.
