RNA engineered T cells for the treatment of cancer
View Patent ↗The present invention relates to compositions and methods for generating RNA Chimeric Antigen Receptor (CAR) transfected T cells. The RNA-engineered T cells can be used in adoptive therapy to treat cancer.
1. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the RNA is transcribed from an in vitro transcription vector, wherein the vector comprises the nucleic acid sequence of SEQ ID NO: 4.
2. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the DNA from which the RNA is transcribed comprises a sequence selected from the group consisting of SEQ ID NO: 6 and SEQ ID NO: 8.
3. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the RNA is transcribed from an in vitro transcription vector, wherein the vector comprises the nucleic acid sequence of SEQ ID NO: 5.
4. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the DNA from which the RNA is transcribed comprises a sequence selected from the group consisting of SEQ ID NO: 7, SEQ ID NO: 9, SEQ ID NO: 19, SEQ ID NO: 20, SEQ ID NO: 21, SEQ ID NO: 22, SEQ ID NO: 23 and SEQ ID NO: 24.
5. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the RNA is transcribed from an in vitro transcription vector, wherein the vector comprises the nucleic acid sequence of SEQ ID NO: 28.
6. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA, wherein the RNA comprises a nucleic acid sequence encoding an extracellular domain, a transmembrane domain, a costimulatory signaling region, and a signaling domain of CD3-zeta, and wherein the DNA from which the RNA is transcribed comprises a sequence selected from the group consisting of SEQ ID NO: 10, SEQ ID NO: 11, SEQ ID NO: 12 and SEQ ID NO: 13.
7. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA encoding a chimeric antigen receptor (CAR), wherein the RNA is transcribed from an in vitro transcription vector, wherein the vector comprises the nucleic acid sequence of SEQ ID NO: 27.
8. An activated T cell comprising a transfected in vitro transcribed RNA or synthetic RNA, wherein the RNA comprises a nucleic acid sequence encoding an extracellular domain, a transmembrane domain, a costimulatory signaling region, and a signaling domain of CD3-zeta, and wherein the DNA from which the RNA is transcribed comprises a sequence selected from the group consisting of SEQ ID NO: 14, SEQ ID NO: 15, SEQ ID NO: 16, SEQ ID NO: 17 and SEQ ID NO: 18.
