  • Publication number: 20220251534
    Abstract: The present disclosure relates to protein sequences which can be used to generate factor Xa proteins and derivatives thereof. The protein sequences include a factor Xa light chain portion, a heavy chain catalytic domain portion, and an activation peptide C-terminal to the heavy chain catalytic domain portion. It is discovered that when an activation peptide (AP) is fused to the C-terminal end of the heavy chain of the factor Xa protein or derivative, the resulting protein can be more efficiently expressed, and the attachment of the activation peptide (AP) to the heavy chain does not affect the activity of the protein.

  • Publication number: 20220125894
    Abstract: The present disclosure relates to compositions and methods useful for assessing the efficacy in a patient having suffered from intracranial hemorrhage while undergoing an anticoagulation treatment with a factor Xa (fXa) inhibitor. The method can include administering to the patient a fXa derivative that has reduced catalytic activity as compared to the wild-type fXa protein, is capable of binding to the factor Xa inhibitor and cannot assemble into a prothrombinase complex; obtaining a blood sample from the patient following the administration; and measuring an anti-fXa activity in the sample, wherein the anti-fXa activity reflects the hemostatic efficacy in the patient. Once the assessment is made, suitable medical interventions can be implemented.
