Chimeric antigen receptors targeting CD-19
The invention is directed to a chimeric antigen receptor (CAR) directed against CD19, which comprises an amino acid sequence of any one of SEQ ID NO: 1-SEQ ID NO: 13. The invention also provides T-cells expressing the CAR and methods for destroying malignant B-cells.
1. A method of treating or preventing a B-cell malignancy in a subject,
the method comprising administering to the subject an effective amount of one or more T cells or NK cells comprising a vector,
wherein the vector comprises a nucleic acid encoding a chimeric antigen receptor (CAR) directed against CD19, wherein the CAR comprises an amino acid sequence of SEQ ID NO: 1, SEQ ID NO: 2, SEQ ID NO: 3, SEQ ID NO: 4, SEQ ID NO: 5, SEQ ID NO: 6, SEQ ID NO: 7, SEQ ID NO: 8, SEQ ID NO: 9, SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12, or SEQ ID NO: 13, and
wherein the B-cell malignancy is leukemia, lymphoma, or multiple myeloma.
2. The method of claim 1 , wherein the CAR comprises an amino acid sequence of SEQ ID NO: 10.
3. The method of claim 1 , wherein the B-cell malignancy is multiple myeloma.
4. The method of claim 1 , wherein the B-cell malignancy is leukemia.
5. The method of claim 4 , wherein the leukemia is chronic lymphocytic leukemia.
6. The method of claim 1 , wherein the B-cell malignancy is lymphoma.
7. The method of claim 6 , wherein the lymphoma is follicular lymphoma, mantle-cell lymphoma, Burkitt lymphoma, diffuse large B-cell lymphoma, Hodgkin lymphoma, lymphoplasmacytic lymphoma, or marginal-zone lymphoma.
8. The method of claim 1 , wherein the method comprises administering to the subject an effective amount of the one or more T cells comprising the vector.
9. The method of claim 1 , wherein the method comprises administering to the subject an effective amount of the one or more NK cells comprising the vector.
10. The method of claim 1 , wherein the method is a method of treating a B-cell malignancy in a subject.
11. The method of claim 10 , wherein the CAR comprises an amino acid sequence of SEQ ID NO: 10.
12. The method of claim 10 , wherein the B-cell malignancy is multiple myeloma.
13. The method of claim 10 , wherein the B-cell malignancy is leukemia.
14. The method of claim 10 , wherein the B-cell malignancy is lymphoma.
15. The method of claim 11 , wherein the B-cell malignancy is multiple myeloma and wherein the method comprises administering to the subject an effective amount of the one or more T cells comprising the vector.
16. The method of claim 11 , wherein the B-cell malignancy is leukemia and wherein the method comprises administering to the subject an effective amount of the one or more T cells comprising the vector.
17. The method of claim 11 , wherein the B-cell malignancy is lymphoma and wherein the method comprises administering to the subject an effective amount of the one or more T cells comprising the vector.
18. The method of claim 11 , wherein the B-cell malignancy is multiple myeloma and wherein the method comprises administering to the subject an effective amount of the one or more NK cells comprising the vector.
19. The method of claim 11 , wherein the B-cell malignancy is leukemia and wherein the method comprises administering to the subject an effective amount of the one or more NK cells comprising the vector.
20. The method of claim 11 , wherein the B-cell malignancy is lymphoma and wherein the method comprises administering to the subject an effective amount of the one or more NK cells comprising the vector.
