Abstract

Official abstract text for this publication.

Nucleic acid molecules that include a nucleotide sequence encoding a chimeric antigen receptor (CAR) and a nucleotide sequence encoding a protease sensitive scFv, wherein the chimeric antigen receptor comprises: an scFv targeting a tumor antigen, a spacer, a transmembrane domain, a co-stimulatory domain, and a CD3ζ signaling domain; and the protease-sensitive scFv and the scFv target the same tumor antigen are described.

First claim

Opening claim text (preview).

What is claimed is: 1. A nucleic acid molecule comprising: (a) a nucleotide sequence encoding a chimeric antigen receptor (CAR) comprising amino acids 23 to 665 of SEQ ID NO: 31 and (b) a nucleotide sequence encoding a protease sensitive scFv comprising, from amino to carboxy terminus, a VH domain comprising SEQ ID NO: 33 and a VL domain SEQ ID NO:34 joined by a protease-sensitive linker that is sensitive to MMP-2 or MMP-9. 2. An expression vector comprising the nucleic acid molecule of claim 1 . 3. A viral vector comprising the nucleic acid molecule of claim 1 . 4. A population of human T cells transduced by a vector comprising the nucleic acid molecule of claim 1 . 5. A method of treating cancer in a patient comprising administering a population of autologous or allogeneic human T cells transduced by a vector comprising the nucleic acid molecule of claim 1 . 6. The method of claim 5 , wherein MMP-2 or MMP-9 is present in the tumor microenvironment. 7. The nucleic acid molecule of claim 1 , wherein the protease sensitive scFv comprises the amino acid sequence of SEQ ID NO: 38 or SEQ ID NO: 39.
