The present invention provides chimeric FVII molecules comprising FVII an XTEN polypeptide and an antibody and antigen binding molecules thereof which specifically bind the a and/or ß subunits of the non active form of the GPIIb/IIIIa receptor. The antibodies and antigen binding molecules can be genetically fused and/or conjugated to heterologous moieties half life extending moiety. The invention also includes methods of producing and using the chimeric molecules.
