Abstract
The invention provides conjugates comprising a coagulating agent conjugated to an antibody, where the antibody specifically binds an extracellular domain epitope of a mammalian PLVAP protein. These agents specifically target HCC tumors and treat the HCC. The invention also provides methods of using these conjugates, such as methods of treating HCC by administering the conjugates provided by the invention or compositions provided by the invention, such as pharmaceutical compositions.
Claims9
A conjugate comprising a tissue factor (TF) having an amino acid sequence at least 80% identical to SEQ ID NO:1 conjugated to an antibody, wherein the antibody comprises:
- a) complementarity determining regions (CDR) 1-3 of the heavy chain variable region (HCVR) comprising the amino acid sequence of SEQ ID NO:3, and CDRs 1-3 of the light chain variable region (LCVR) comprising the amino acid sequence of SEQ ID NO:
- 4, and wherein the antibody specifically binds to an extracellular domain epitope of a mammalian plasmalemma vesicle associated protein (PLVAP) having the sequence set forth in SEQ ID NO:25;
- or b) CDRs 1-3 of the HCVR comprising the amino acid sequence of SEQ ID NO:5, and CDRs 1-3 of the LCVR comprising the amino acid sequence of SEQ ID NO:6, and wherein the antibody specifically binds to an extracellular domain epitope of a mammalian PLVAP having the sequence set forth in SEQ ID NO:26.
A conjugate comprising a tissue factor (TF) having an amino acid sequence at least 90% identical to SEQ ID NO:1 conjugated to an antibody that binds an extracellular domain epitope of human plasmalemma vesicle associated protein (PLVAP), wherein the antibody comprises:
- a) complementarity determining regions (CDR) 1-3 of the heavy chain variable region (HCVR) comprising the amino acid sequence of SEQ ID NO:3, and CDRs 1-3 of the light chain variable region (LCVR) comprising the amino acid sequence of SEQ ID NO:4;
- or
- b) CDRs 1-3 of the HCVR comprising the amino acid sequence of SEQ ID NO:5, and CDRs 1-3 of the LCVR comprising the amino acid sequence of SEQ ID NO:6.
