Abstract

The invention relates to human targets of interest (TOI), anti-TOI ligands, kits compositions and method.

Claims

1. A method of treating a solid tumor;

melanoma;

renal cell carcinoma;

non small-cell lung cancer;

bladder cancer;

Hodgkin'"'"'s lymphoma;

or gastric cancer;

in a human, the method comprising administering to said human an anti-PD-L1 antibody or antibody fragment that specifically binds to a human PD-L1 that is expressed by a PD-L1 nucleotide sequence comprising a variation selected from the group consisting of;

rs148141792;

rs369350813;

rs10481593;

rs2282055;

rs2297135;

rs2297136;

rs2297137;

rs3780395;

rs7023227;

rs34028061;

rs7041009;

rs148170925;

rs10114060;

rs1536926; and

rs7042084;

wherein the antibody or antibody fragment that specifically binds to human PD-L1 comprises a human gamma-1 heavy chain constant region that comprises an amino acid selected from the group consisting of;

an Asp corresponding to position 204 of SEQ ID NO;

42 and a Leu corresponding to position 206 of SEQ ID NO;

42; and

wherein said human comprises;

(i) an IGHG1*01 human heavy chain constant region gene segment, or the human expresses antibodies comprising human gamma-1 heavy chain constant regions comprising said selected amino acid; and

(ii) a PD-L1 nucleotide sequence comprising said selected variation.

2. The method of claim 1, wherein said human is homozygous for said variation.

3. The method of claim 1, wherein the antibody or antibody fragment that specifically binds to human PD-L1 comprises an IGHG1*01 human heavy chain constant region.

4. The method of claim 1, wherein the cancer is a solid tumor.

5. The method of claim 1, comprising, before said administering, selecting a human comprising said PD-L1 nucleotide sequence of (ii), wherein the human is the human of claim 1.

6. The method of claim 1, wherein the human has been determined to comprise said PD-L1 nucleotide sequence of (ii).

7. The method of claim 1, comprising the step of determining that the human comprises said PD-L1 nucleotide sequence of (ii), optionally, wherein the determining step is performed before administration of the antibody or antibody fragment that specifically binds to human PD-L1 to the human.

8. The method of claim 7, wherein the step of determining comprises assaying a biological sample from the human for a PD-L1 nucleotide sequence comprising said selected variation.

9. The method of claim 8, wherein the assaying comprises contacting the biological sample with

a. at least one oligonucleotide probe comprising a sequence of at least 10 contiguous nucleotides that can specifically hybridize to and identify in the biological sample a nucleotide sequence comprising said selected variation or that specifically hybridizes to an antisense of said sequence, wherein said nucleic acid hybridizes to said selected variation or hybridizes to an antisense sequence thereby forming a complex when at least one nucleotide sequence comprising said selected variation is present;

and/or

b. at least one oligonucleotide probe comprising a sequence of at least 10 contiguous nucleotides of a nucleotide sequence comprising said selected variation or comprising an antisense sequence of said contiguous nucleotides, wherein said sequence of contiguous nucleotides comprises said selected variation thereby forming a complex when the nucleotide sequence comprising said selected variation is present; and

detecting the presence or absence of the complex, wherein detecting the presence of the complex determines that the human comprises a PD-L1 nucleotide sequence comprising said selected variation.

10. The method of claim 8, wherein the assaying comprises nucleic acid amplification and optionally one or more methods selected from sequencing, next generation sequencing, nucleic acid hybridization, and allele-specific amplification and/or wherein the assaying is performed in a multiplex format.

11. The method of claim 1, wherein said human is or has been further determined to be substantially resistant a PD-L1 or PD-1 treatment.

12. The method of claim 1, wherein said human is receiving or has received a PD-L1 or PD-1 treatment or has reduced responsiveness to a PD-L1 or PD-1 treatment.

13. The method of claim 8, wherein said biological sample comprises serum, blood, faeces, tissue, a cell, urine and/or saliva of said human.

14. The method of claim 1, wherein said antibody or antibody fragment that specifically binds to human PD-L1 is administered by intravenous or subcutaneous injection and/or is comprised in an injectable preparation.

15. The method of claim 1, wherein the antibody or antibody fragment that specifically binds to human PD-L1 is a human antibody or antibody fragment.
