The present invention relates to mutated factor (FX) polypeptides and uses thereof for the treatment of haemophilia. In particular, the present invention relates to a mutated factor X (FX) polypeptide which comprises a heavy chain wherein at least one amino acid residue at position 401 or 408 is mutated.

The present invention relates antidotes to anticoagulants targeting factor Xa. The antidotes are factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. The derivatives describe herein lack or have reduced intrinsic coagulant activity. Disclosed herein are methods of stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.

The present invention relates to methods and compositions for improving the productivity of recombinant vitamin K dependent protein expression in host cells.

The present disclosure relates to solutions and methods of preparing lyophilized formulations of factor Xa (fXa) antidotes. A suitable aqueous formulation suitable for lyophilization can include a fXa antidote, a solubilizing agent, a stabilizer, and a crystalline component, wherein the formulation does not collapse during lyophilization.

The present invention relates antidotes to anticoagulants targeting factor Xa. The antidotes are factor X and factor Xa protein derivatives that bind to the factor Xa inhibitors thereby substantially neutralizing them but do not assemble into the prothrombinase complex. The derivatives describe herein lack or have reduced intrinsic coagulant activity. Disclosed herein are methods of reversing anticoagulation, stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.

The present invention relates unit dose formulations of antidotes to anticoagulants targeting factor Xa. Disclosed herein are methods of stopping or preventing bleeding in a patient that is currently undergoing anticoagulant therapy with a factor Xa inhibitor.

The disclosure provides compositions and methods for counteracting the effects of direct activated Factor X (FXa) inhibitors in a subject by administering a variant of FXa.

The present invention relates to improved clotting compositions for producing high quality blood serum samples for analyte testing, such as for pathology testing and other biological assays. In particular, the present invention relates to the use of prothrombin activators in combination with stabilizing agents such as colloids for producing high quality blood serum samples. The present invention also relates to associated methods for preparing clotting compositions, tubes, kits and methods of diagnosis, prognosis and monitoring for responsiveness to therapy.

The present invention relates to mutated factor (FX) polypeptides and uses thereof for the treatment of haemophilia. In particular, the present invention relates to a mutated factor X (FX) polypeptide wherein the heavy chain comprises at least one mutation selected from the group consisting of: the mutation which consists of the substitution of the glutamic acid residue (E) at position 215 by a glutamine residue (Q), an asparagine residue (N), a serine residue (S), an alanine residue (A), or a tyrosine residue (Y); the mutation which consists of the substitution of the glutamic acid residue (E) at position 216 by a glutamine residue (Q); and the mutation which consists of the substitution of the glutamic acid residue (E) at position 218 by a glutamine residue (Q);

The present disclosure relates to solutions and methods of preparing lyophilized formulations of factor Xa (fXa) antidotes. A suitable aqueous formulation suitable for lyophilization can include a fXa antidote, a solubilizing agent, a stabilizer, and a crystalline component, wherein the formulation does not collapse during lyophilization.
