Abstract

Genetically modified compositions, such as non-viral vectors and T cells, for treating cancer are disclosed. Also disclosed are the methods of making and using the genetically modified compositions in treating cancer.

First claim

What is claimed is:

1. A method for treating a cancer in a subject, wherein said cancer comprises cancer cells that express a neoantigen, said method comprising: administering to said subject a pharmaceutical composition that comprises a population of ex vivo engineered primary lymphocytes that express an endogenous or exogenous T cell receptor (TCR), wherein said ex vivo engineered primary lymphocytes comprise a gene disruption in a target site in a region corresponding to exon 2 or exon 3 of the genome of the human cytokine inducible SH2-containing protein (CISH) of SEQ ID NO: 103, wherein said gene disruption is a targeted double strand break at the target site, and wherein said gene disruption is introduced by a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) system comprising a Cas9 nuclease and a guide ribonucleic acid (gRNA), wherein said gRNA is at least 15 contiguous base pairs complementary to 15 base pairs of exon 2 or exon 3 of the CISH genomic sequence, wherein said gRNA hybridizes to a CISH gene sequence that comprises a sequence having at least 80% identity to one of SEQ ID NOS: 75-86, and wherein said double strand break results in an efficiency of integration of an exogenous polynucleic acid at the CISH locus of human T cells of at least 60% as measured by tracking of indels by decomposition (TIDE) analysis.

2. The method of claim 1 , wherein said ex vivo engineered primary lymphocytes are autologous to said subject.

3. The method of claim 2 , wherein said ex vivo engineered primary lymphocytes are tumor infiltrating lymphocytes.

4. The method of claim 3 , further comprising expanding said tumor infiltrating lymphocytes to at least about 5×10 7 cells before the genomic disruption.

5. The method of claim 1 , wherein said gene disruption is within 10 base pairs of a first nucleotide of a protospacer adjacent motif (PAM) sequence.

6. The method of claim 1 , wherein said guide ribonucleic acid (gRNA) hybridizes to a CISH gene sequences that comprises a GA sequence or a GG sequence.

7. The method of claim 1 , wherein said guide ribonucleic acid (gRNA) hybridizes to a CISH gene sequence that comprises a sequence that has at least 80% identity to SEQ ID NO.: 82.

8. The method of claim 7 , wherein said guide ribonucleic acid (gRNA) hybridizes comprises a sequence that has at least 90% identity to SEQ ID NO.: 82.

9. The method of claim 1 , wherein 70% or more of said ex vivo engineered primary lymphocytes are viable.

10. The method of claim 1 , wherein said pharmaceutical composition comprises at least 1×10 9 of said ex vivo engineered primary lymphocytes.

11. The method of claim 1 , wherein said method further comprises administering cyclophosphamide, fludaribine, or a combination thereof, to said subject.

12. The method of claim 1 , further comprising expanding said ex vivo engineered primary lymphocytes using a Rapid Expansion Protocol (REP) for up to 2 weeks prior to said administering.

13. The method of claim 1 , wherein said cancer is selected from the group consisting of: melanoma, gastrointestinal cancer, breast cancer, prostate cancer, myeloma, lymphoma, sarcoma, pancreatic cancer, liver cancer, lung cancer, thyroid cancer, brain cancer, hematopoietic cancer, esophageal cancer, bone cancer, bladder cancer, cervical cancer, ovarian cancer, and any combination thereof.

14. The method of claim 13 , wherein said cancer is gastrointestinal cancer.

15. The method of claim 1 , wherein said cancer is a solid tumor cancer.

16. The method of claim 1 , wherein said subject is a human.

17. The method of claim 1 , wherein said ex vivo engineered primary lymphocytes comprise T cells.

18. A method for treating a solid tumor cancer in a human subject, wherein said solid tumor cancer comprises cancer cells that express a neoantigen, said method comprising: administering to said human subject a pharmaceutical composition that comprises a population of ex vivo engineered primary tumor infiltrating lymphocytes that express an endogenous or exogenous T cell receptor (TCR), wherein said ex vivo engineered primary tumor infiltrating lymphocytes comprise a gene disruption in a target site in a region corresponding to exon 2 or exon 3 of the genome of the human cytokine inducible SH2-containing protein (CISH) of SEQ ID NO: 103, wherein said gene disruption is a targeted double strand break at the target site, and wherein said gene disruption is introduced by a Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) system comprising a Cas9 nuclease and a guide RNA (gRNA), wherein said gRNA is at least 15 contiguous base pairs complementary to 15 base pairs of exon 2 or exon 3 of the CISH genomic sequence, wherein said gRNA hybridizes to a CISH gene sequence that comprises a GA sequence or a GG sequence having at least 80% identity to one of SEQ ID NOS: 75-86, and wherein said double strand break results in an efficiency of integration of an exogenous polynucleic acid at the CISH locus of human T cells of at least 60% as measured by tracking of indels by decomposition (TIDE) analysis.

19. The method of claim 18 , wherein said solid tumor cancer is gastrointestinal cancer.

20. The method of claim 18 , wherein said ex vivo engineered primary tumor infiltrating lymphocytes are autologous to said subject.

21. The method of claim 18 , wherein said guide ribonucleic acid (gRNA) hybridizes to a CISH gene sequence that comprises a sequence that has at least 80% identity to SEQ ID NO.: 82.

22. The method of claim 18 , wherein 70% or more of said ex vivo engineered primary tumor infiltrating lymphocytes are viable.

23. The method of claim 18 , wherein said method further comprises administering cyclophosphamide, fludaribine, or a combination thereof, to said subject.
