Targeting modules for universal chimeric antigen receptor expressing immune cells and use in the treatment of cancer infections and autoimmune disorders
The present invention relates to a targeting module comprising a chemically synthesized peptide binding moiety specific for a human cell surface protein or protein complex, a kit comprising the targeting module and a vector or a cell comprising a nucleic acid encoding a universal chimeric antigen receptor and the use for the treatment of cancer, infections and autoimmune disorders.
1. A targeting module comprising:
a glutamate-urea-lysine motif,
a chelator, and
a tag, wherein the tag comprises a human nuclear La protein epitope selected from SEQ ID NOs: 25 and 27.
2. The targeting module according to claim 1 , selected from
which contains SEQ ID NO: 28, and
which contains SEQ ID NO: 27,
wherein Z is a chelator
n is an integer
is 2 or more.
3. A pharmaceutical composition comprising a targeting module according to claim 1 .
4. A method for the treatment of a prostate specific membrane antigen expressing cancer comprising administering to a patient the targeting module according to claim 1 and a vector or a cell comprising a nucleic acid encoding a universal chimeric antigen receptor that comprises:
a tag-binding domain comprising
a variable region heavy chain comprising SEQ ID NO: 21 and a variable region light chain comprising SEQ ID NO: 22, or
a variable region heavy chain comprising SEQ ID NO: 23 and a variable region light chain comprising SEQ ID NO: 24;
an extracellular hinge and a transmembrane domain; and
a signal transduction domain.
5. The method of claim 4 , wherein the targeting module has a structure selected from
which contains SEQ ID NO: 25, and
which contains SEQ ID NO: 27

The method of claim 4 , wherein the signal transduction domain is selected from the group consisting of cytoplasmic regions of CD28, CD137 (4-1BB), CD134 (OX40), DAP10 and CD27, programmed cell death-1 (PD-1), cytotoxic T-lymphocyte antigen 4 (CTLA-4), cytoplasmic regions of CD3 chains, DAP12, and activating Fc receptors.
8. The method of claim 4 , wherein the nucleic acid comprises a nucleotide sequence according to SEQ ID NO: 1, 9, 13 or 16 encoding for a universal chimeric antigen receptor with an amino acid sequence according to SEQ ID NO: 17, 18, 19, or 20.
9. A kit comprising
a) a targeting module according to claim 1 and
b) a vector or a cell comprising a nucleic acid encoding a universal chimeric antigen receptor that comprises:
a tag-binding domain comprising
a variable region heavy chain comprising SEQ ID NO: 21 and a variable region light chain comprising SEQ ID NO: 22, or
a variable region heavy chain comprising SEQ ID NO: 23 and a variable region light chain comprising SEQ ID NO: 24;
an extracellular hinge and a transmembrane domain; and
a signal transduction domain.
10. The kit according to claim 9 , wherein the extracellular hinge and transmembrane domain is selected from hinge and transmembrane domains of human CD28 molecule, CD8a chain NK cell receptors parts of the constant region of an antibody, and combinations thereof.
11. The kit according to claim 9 , wherein the signal transduction domain is selected from the group consisting of cytoplasmic regions of CD28, CD137 (4-1BB), CD134 (OX40), DAP10 and CD27, programmed cell death-1 (PD-1), cytotoxic T-lymphocyte antigen 4 (CTLA-4), cytoplasmic regions of CD3 chains, DAP12, and activating Fc receptors.
12. The kit according to claim 9 , wherein the nucleic acid comprises a nucleotide sequence according to SEQ ID NO: 1, 9, 13 or 16 encoding for a universal chimeric antigen receptor with an amino acid sequence according to SEQ ID NO: 17, 18, 19, or 20.
