Compositions and methods for treating cancer with anti-CD19 immunotherapy
Chimeric antigen receptors containing human CD19 antigen binding domains are disclosed. Nucleic acids, recombinant expression vectors, host cells, antigen binding fragments, and pharmaceutical compositions, relating to the chimeric antigen receptors are also disclosed. Methods of treating or preventing cancer in a subject, and methods of making chimeric antigen receptor T cells are also disclosed.
1. An isolated nucleic acid molecule encoding a chimeric antigen receptor (CAR), wherein the CAR comprises the amino acid sequence of SEQ ID NO: 20, 22, 24, 26, 28, 30, 32, or 34.
2. A chimeric antigen receptor (CAR) encoded by the isolated nucleic acid molecule of claim 1 .
3. A pharmaceutical composition comprising a population of isolated human T cells, wherein the isolated human T cells comprise a nucleic acid sequence that encodes the chimeric antigen receptor (CAR) of claim 2 and wherein the isolated human T cells are isolated from a human having a cancer.
4. The pharmaceutical composition of claim 3 , wherein the cancer is a hematological cancer.
5. The pharmaceutical composition of claim 4 , wherein the hematological cancer is leukemia or lymphoma.
6. The pharmaceutical composition of claim 5 , wherein the leukemia is chronic lymphocytic leukemia (CLL), acute lymphocytic leukemia (ALL), or chronic myelogenous leukemia (CML).
7. The pharmaceutical composition of claim 5 , wherein the lymphoma is mantle cell lymphoma, non-Hodgkin's lymphoma or Hodgkin's lymphoma.
8. The pharmaceutical composition of claim 4 , wherein the hematological cancer is multiple myeloma.

10. A vector comprising a nucleic acid molecule of claim 1 .
11. The vector of claim 10 , wherein the vector is selected from the group consisting of a DNA vector, an RNA vector, a plasmid vector, a cosmid vector, a herpes virus vector, a measles virus vector, a lentivirus vector, an adenoviral vector, a retrovirus vector, and a combination thereof.
12. The vector of claim 10 , further comprising a promoter.
13. The vector of claim 12 , wherein the promoter is an inducible promoter, a constitutive promoter, a tissue specific promoter, a suicide promoter or any combination thereof.
14. An isolated cell comprising the vector of claim 10 .
15. The isolated cell of claim 14 , wherein the isolated cell is a T cell.
16. The isolated cell of claim 14 , wherein the isolated T cell is a CD8+ T cell.
