Abstract

The invention provides a chimeric antigen receptor (CAR) comprising an antigen binding domain comprising SEQ ID NOs: 1-6, a transmembrane domain, and an intracellular T cell signaling domain. Nucleic acids, recombinant expression vectors, host cells, populations of cells, antibodies, or antigen binding portions thereof, and pharmaceutical compositions relating to the CARs are disclosed. Methods of detecting the presence of cancer in a mammal and methods of treating or preventing cancer in a mammal are also disclosed.

Claims (18)

1. A chimeric antigen receptor (CAR) comprising an antigen binding domain comprising the amino acid sequences of SEQ ID NOs: 1-6, a transmembrane domain, and an intracellular T cell signaling domain.

2. The CAR according to claim 1 , wherein the antigen binding domain comprises a light chain variable region comprising an amino acid sequence comprising SEQ ID NO: 7.

3. The CAR according to claim 1 , wherein the antigen binding domain comprises a heavy chain variable region comprising an amino acid sequence comprising SEQ ID NO: 8.

4. The CAR according to claim 1 , wherein the antigen binding domain comprises an amino acid sequence comprising SEQ ID NO: 9.

5. The CAR according to claim 1 , wherein the antigen binding domain comprises a linker comprising SEQ ID NO: 11.

6. The CAR according to claim 1 , further comprising a leader sequence comprising SEQ ID NO: 10.

7. The CAR according to claim 1 , wherein the transmembrane domain comprises i) a transmembrane portion of a CD8 and/or ii) a transmembrane portion of a CD28.

8. The CAR according to claim 1 , wherein the transmembrane domain comprises an amino acid sequence comprising SEQ ID NO: 12 or 18 and/or an amino acid sequence comprising SEQ ID NO: 15.

9. The CAR according to claim 1 , wherein the intracellular T cell signaling domain comprises one or more of i) an intracellular signaling portion of a CD28, ii) an intracellular signaling portion of a CD137, and iii) an intracellular signaling portion of a CD3 zeta.

10. The CAR according to claim 1 , wherein the intracellular T cell signaling domain comprises an amino acid sequence comprising SEQ ID NO: 16 or 19.

11. The CAR according to claim 1 , wherein the intracellular T cell signaling domain comprises an amino acid sequence comprising SEQ ID NO: 13 or 20.

12. The CAR according to claim 1 , wherein the intracellular T cell signaling domain comprises an amino acid sequence comprising SEQ ID NO: 14, 17 or 21.

13. The CAR according to claim 1 , comprising an amino acid sequence comprising any one of SEQ ID NOs: 22-24.

14. The CAR according to claim 1 , wherein the intracellular T cell signaling domain comprises an intracellular signaling portion of a CD28 or comprises an intracellular signaling portion of a CD137 and wherein the CAR does not comprise an intracellular signaling portion of both a CD28 and a CD137.

15. The CAR according to claim 14 , wherein the CAR does not comprise an intracellular signaling domain of more than one T cell costimulatory molecule.

16. The CAR of claim 1 , comprising and amino acid sequence comprising SEQ ID NO: 22.

17. The CAR of claim 1 , comprising and amino acid sequence comprising SEQ ID NO: 23.

18. The CAR of claim 1 , comprising and amino acid sequence comprising SEQ ID NO: 24.
