Description

The Pharmaceutical composition that contains factor VII polypeptides and factor XI, plasma thromboplastin antecedent polypeptide
Technical field
The present invention relates to contain the Pharmaceutical composition of factor VII or factor VII-dependency polypeptide and factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide.The invention still further relates to factor VII or factor VII-dependency polypeptide and combine with factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide and be used to prepare treatment and suffer from the experimenter of bleeding episodes, or prevent the purposes in the medicine of its outbreak.The invention still further relates to the method for treatment experimenter bleeding episodes and promote the experimenter to form the method for blood coagulation.The invention still further relates to the test kit that contains these chemical compounds.
Background technology
Hemostasis is exposed to after by vascular damaged in tissue factor (TF) in the blood circulation and the circulation starts to form complex between the FVIIa that exists corresponding to about 1% total FVII protein quality.This complex anchor on the cell that carries TF and on cell surface and FX to be activated into FXa and FIX is activated into FIXa.FXa activates into thrombin with thrombinogen, and the latter activates FVIII, FV, FXI and FXIII.In addition, the limited amount thrombin that forms in the hemostasis initial step also activates platelet.Work its alteration of form of back and expose the charged phospholipid on its surface of thrombin on platelet.This activated platelet surface forms the template that FX further activates and thrombin fully produces.By forming the FIXa-FVIIIa complex, make and further activate FX that FXa still is transformed into thrombin on this surface with thrombinogen then at activated platelet surface at activated platelet surface.Thrombin is transformed into fibrinogen insoluble and stablizes the fibrin of initial platelet thromboembolism then.This process is compartmentalization, promptly is confined to the site that TF expresses or exposes, thereby makes general activate the risk minimization of blood coagulation system.The thromboembolism that insoluble fibrin forms is crosslinked further stable by the catalytic fibrin fiber of FXIII-.
FVIIa mainly exists with the strand proenzyme in blood plasma, and this proenzyme is cracked into its double-stranded activated form, i.e. FVIIa by FXa.Developed reorganization activation factor VIIa (rFVIIa) as short hemostasis (pro-haemostatic) agent.Can not use rFVIIa among the hemorrhage hemophilia experimenter with suffering from of thrombin product treatment owing to form antibody, can produce rapidly and short efficiently hemostasis reaction.Also can successfully treat the hemorrhage experimenter who suffers from factor VII deficiency or have normal blood coagulation system but the too much hemorrhage experimenter of generation with FVIIa.In these researchs, do not find the adverse side effect (thromboembolism particularly occurring) of rFVIIa.
The thrombin that the extra exogenous FVIIa of using is increased on the activated platelet surface forms.This takes place in the hemophilia experimenter of the effective way that lacks that thereby FIX or FVIII forfeiture thrombin fully forms.In addition, have under the situation of functional defect in platelet counts reduction or platelet, extra FVIIa increases thrombin and forms.
The article of commerce of recombined human FVIIa is sold (Novo NordiskA/S, Denmark) with NovoSeven .Novoseven  indicates the bleeding episodes that is used for the treatment of hemophilia A and B patient.Novoseven  is the obtainable unique reorganization FVIIa that is used for effectively and reliably treating bleeding episodes on the market.
FXI is the component of intrinsic coagulation approach.FXI lack with particularly in tissue with highly local fibrinolytic activity slightly to arrive the hemorrhage disorder of moderate relevant.On the contrary, it is believed that high-caliber FXI is the risk factor of venous thrombosis.FXI is by FXIIa, the proenzyme of thrombin and the activated trypsin-like serine protease of FXIa.Activatory FXI (FXIa) participates in the activation of FIX, and the latter (combines with FVIII) again and further activates FX and therefore cause thrombin generation.
Relevant with operation or the severe trauma experimenter who goes out hyperhematosis and need blood transfusion does not form more complication and knows than experiencing any hemorrhage experimenter.Yet the hemorrhage needs of moderate are used human blood or blood products (platelet, leukocyte, the concentrate that is used for the treatment of the blood plasma source of blood coagulation defective, Deng) also can cause and the relevant complication of danger of transmitting Human virus's (hepatitis, virus that HIV, parvovirus and other are unknown so far).The a large amount of blood transfusions of extensive hemorrhage needs can cause forming the depletion of a plurality of organs, comprise infringement lung and renal function.In case the experimenter forms these severe complications, the cascade event and the inflammatory reaction that relate to many cytokines just begin, make any treatment all very the difficulty and unfortunately all get nowhere usually.Therefore, the main target in operation and the treatment of serious tissue injury be avoid or minimize hemorrhage.For fear of or minimize this hemorrhagely, guarantee to form that to be not easy by the dissolved stabilization of solid tampon of fibrinoclase be important.And, importantly guarantee fast and effectively to form this thromboembolism or blood coagulation.
Now, the experimenter of experience bleeding episodes, comprise the wound victim and with the relevant hemorrhage experimenter of operation, treat with injection or infusion FVIIa several times usually, the hemostatic capability of certain level is kept in the administration more than need be once because of the half life of FVIIa short (2.5 hours).The quickening prevention is hemorrhage to have important benefits to this experimenter.It also is like this stopping minimizing hemorrhage and that keep the required administration number of times of hemostasis.
Japanese patent application 59-116213A relates to and contains the aerosol composition of coagulant as active ingredient as tissue adhesive.This coagulant is optional from thrombin I, II, III, IV, V, VII, VIII, IX, X, XI, XII, and XIII, prekallikrein, high polymer kininogen and thrombin.The combination of preferred F XIII and thrombin.
The compositions and being used for the treatment of that European patent 225.160 (Novo Nordisk) relates to FVIIa is not the method for the hemorrhagic disease that caused by thrombin defective or blood coagulation factor inhibitors.
The compositions that European patent 82.182 (Baxter Travenol Lab.) relates to factor VIIa in the experimenter to the purposes of anticoagulin defective or as the influence of inhibitor to thrombin.
International Patent Application WO 93/06855 (Novo Nordisk) relates to the topical application of FVIIa.
United States Patent (USP) 5,252,217 relate to the method that preparation is used for the treatment of people's factor XI, plasma thromboplastin antecedent concentrate of purposes.
This area still needs the experimenter of experience bleeding episodes is carried out the modified form treatment, comprises the bleeding episodes that is caused by following reason: by operation, and wound, or the tissue injury of other form causes; The induction type coagulopathy is included in the coagulopathy among the experimenter who repeatedly transfuses blood; Congenital or acquired blood coagulation or hemorrhagic disease comprise that liver function reduces (" hepatic disease "); Deficiency platelet function or number of platelets reduce; Main blood coagulation " chemical compound " (for example, platelet or Feng. von willebrand's factor albumen) shortage or unusual; Fibrinolysis increases; Anticoagulant therapy or thrombolytic therapy; Or stem cell transplantation.

Detailed Description Of The Invention
The too much hemorrhage and experimenter that therefore need transfuse blood who interrelates with operation or severe trauma does not form more complication than experiencing any hemorrhage experimenter.Yet, moderate is hemorrhage to give human blood or blood products (platelet at needs, leukocyte, the concentrate that is used for the treatment of the blood plasma source of blood coagulation defective, etc.) situation under also can cause complication because this with (for example transmit the Human virus, hepatitis, HIV, parvovirus, or other unknown so far virus) and the danger of non-viral pathogen relevant.The a large amount of blood transfusions of extensive hemorrhage needs can cause forming the depletion of a plurality of organs, comprise infringement lung and renal function.In case the experimenter forms these severe complications, the cascade event and the inflammatory reaction that relate to many cytokines just begin, make any treatment all very the difficulty and unfortunately all get nowhere usually.The patient that experience loses blood seriously is unstable clinically.There is the danger of experiencing auricular fibrillation in this patient, and it can cause that fatal cardiomotility stops; Impaired renal function; Or the lung intravenous extravasation (is also referred to as " wet lung " or ARDS).Therefore, the main target in operation and the treatment of serious tissue injury be avoid or minimize hemorrhage.For fear of or minimize this unwanted hemorrhagely, guarantee to form that to be not easy by the dissolved stabilization of solid tampon of fibrinoclase be important.And, importantly guarantee fast and effectively to form this thromboembolism or blood coagulation.
Experimenter (platelet count or active the reduction) with thrombocytopenia also has impaired thrombin generation and fibrin bolt stabilisation defective, causes tampon dissolving too early easily.In addition, the experimenter who is subjected to severe trauma or organ injury and therefore often accepts blood transfusion has the platelet count of reduction and the fibrinogen of reduction, Factor IX and other blood coagulating protein level usually.The thrombin generation that these experimenters experience impaired (or reduction).Therefore, these experimenters have deficiency, or the lower hemostasis of efficient, cause forming easily and too early by the dissolved fibrin thrombosis of proteolytic enzyme, and this proteolytic enzyme further extensively discharges under the situation that with wound and organ injury on a large scale is feature.
Organize the hemorrhage hematoma that also can cause forming.The degree of injury of the size of hematoma (particularly between cranium and spinal column) and function of nervous system, the rehabilitation difficulty, and/or the seriousness of function of nervous system's permanent damage is closely related with degree after the rehabilitation.The serious consequence that hematoma when hematoma is arranged in brain, occurs, they in addition can cause death.
Therefore, the main purpose in treatments for bleeding is to stop blooding in the shortest time, keeps minimum thereby make to lose blood.
Therefore the invention provides composition beneficial, its purposes and the Therapeutic Method of treatment bleeding episodes in the experimenter of needs treatment.Said composition, purposes is relevant with some beneficial effects with method, it is less to lose blood before described effect is for example stopped blooding, and intra-operative needs blood less, and blood pressure maintains acceptable level before the hemostasis, the blood pressure stabilization quickening, the patient who is treated shortens recovery time, and patient's rehabilitation duration of being treated shortens, and comprises that the hematoma formation minimizing of hematoma in the brain or the hematoma that forms are less, hemorrhage termination is accelerated, and stops the hemorrhage administration number of times required with keeping hemostasis and reduces.
Factor VII or factor VII dependency polypeptide product, for example factor VIIa combines the clotting time of administration with separately with factor VIIa or factor XI, plasma thromboplastin antecedent administration the time with factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide product, blood coagulation hardness is compared with resistance provides the clotting time that shortens, bigger blood coagulation hardness and Fibrinolytic resistance increased.
Factor VII or factor VII dependency polypeptide product (for example factor VIIa) and factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide product are compared in conjunction with the situation of administration with separately with factor VIIa or factor XI, plasma thromboplastin antecedent administration the time, stop the hemorrhage required time to shorten, keep the required administration number of times of hemostasis and reduce.The invention provides simultaneously or the beneficial effect of the goods of the goods of administration factor XI, plasma thromboplastin antecedent successively or factor XI, plasma thromboplastin antecedent dependency polypeptide and factor VII or factor VII dependency polypeptide.Can be the form of single compositions or can be the kit form (test kit of assembling) of a plurality of components according to Pharmaceutical composition of the present invention.Compositions according to the present invention is used as therapeutic and preventative procoagulant in comprising such as the mammal of the mankind's primates.The present invention also provides the method for treatment in comprising human experimenter (comprise prophylactic treatment or prevent) bleeding episodes.
No matter when mention the first or second or the 3rd in this manual, etc., unit dose, it does not represent preferred order of administration, and only is for convenience.
The combination of factor VII or factor VII dependency polypeptide product and factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide product is to guarantee that clotting time shortens, and tampon forms and form a kind of useful product of stable tampon rapidly.The inventor has had been found that the combination of factor VII or factor VII dependency polypeptide and factor XI, plasma thromboplastin antecedent or factor XI, plasma thromboplastin antecedent dependency polypeptide is to guarantee that formation is hard, the useful product of tampon stable and that form fast.
The inventor shows that the combination of factor VIIa and factor XI, plasma thromboplastin antecedent can more effectively shorten human normal plasma's clotting time than independent factor VIIa or factor XI, plasma thromboplastin antecedent.The combination that also shows factor VIIa and factor XI, plasma thromboplastin antecedent can more effectively strengthen blood coagulation hardness than independent factor VIIa or factor XI, plasma thromboplastin antecedent.Combine with also being in the factor XI, plasma thromboplastin antecedent of observing under the concentration that blood coagulation hardness no longer further increases by being in the factor VIIa observed under the concentration that blood coagulation hardness no longer further increases, the unexpected blood coagulation hardness of finding further strengthens.Shown that also the combination of factor VIIa and factor XI, plasma thromboplastin antecedent can more effectively prolong external blood coagulation dissolution time among the human normal plasma than independent factor VIIa or factor XI, plasma thromboplastin antecedent.Shown that also the combination of factor VIIa and factor XI, plasma thromboplastin antecedent can more effectively prolong half blood coagulation dissolution time among the human normal plasma than independent factor VIIa or factor XI, plasma thromboplastin antecedent.Shown that also the combination of factor VIIa and factor XI, plasma thromboplastin antecedent is than independent factor VIIa or factor XI, plasma thromboplastin antecedent more effectively anticoagulative fibrinolysis in the human normal plasma, the particularly fibrinolysis of tPA-mediation.
Therefore, by strengthening blood coagulation, can obtain hemorrhage more effective treatment to the experimenter.
Do not wish to be bound by theory, it is believed that abundant generation thrombin is to form hardly, stable tampon is necessary, and therefore is that to keep hemostasis necessary.The fibrin structure of this thrombosis depend on formation thrombin amount and begin to produce the speed of thrombin.Under the impaired condition of thrombin generation, form highly permeable porous fibrin thrombosis.The fibrinoclase that generally is present in the fibrin surface dissolves this fibrin thrombosis easily.Therefore the formation of stable fibrin thrombosis also depends on the existence of factor XIIIa, and factor XIIIa is by thrombin activation and also depend on thrombin and fully produce.In addition, the fibrinolysis inhibitor of the nearest thrombin activation of describing, promptly TAFI needs quite high thrombin amount be used for its activation.Therefore form under the sufficient inadequately situation at thrombin, TAFI is not activated, and the tampon that causes forming is than easier by the active normal dissolving of normal fiber protein dissolution.Under the situation that number of platelets reduces, i.e. thrombocytopenia, the extraneous factor VIIa of administration of exogenous can start thrombin generation faster.Yet even under high concentration, factor VIIa can not make overall thrombin generation normalization.
In experimenter that the plasma concentration of fibrinogen reduces (because many places wound or operation on a large scale repeatedly experimenter of blood transfusion) thrombin not taking place fully activates.And obtained more effective hemostasis by the administering drug combinations of factor VII and factor XI, plasma thromboplastin antecedent.
The experimenter who suffers from thrombocytopenia has impaired thrombin generation and fibrin thrombosis stabilisation defective, causes tampon dissolving too early easily.In addition, be subjected to the impaired and experimenter that therefore often accept blood transfusion of severe trauma or organ and have the platelet count of reduction and the fibrinogen of reduction usually, Factor IX and other blood coagulating protein level.These experimenters experience the thrombin generation of impaired (reduction).In addition, the activation of the fibrinogen levels negative sense interference factor XIII of its reduction.Therefore, these experimenters have the hemostasis deficiency, or hemostasis efficient is lower, and the fibrin thrombosis that causes forming is dissolved by proteolytic enzyme easily and prematurely, and this proteolytic enzyme is further extensively discharged under the situation that with wound and organ injury on a large scale is feature.
In order to help in the experimenter, to form abundant stable thrombosis, can use according to compositions of the present invention with the whole abilities of the hemostatic kept.Said composition is useful especially in the experimenter that the blood plasma level of experimenter that number of platelets reduces and fibrinogen and/or other blood coagulating protein reduces.
Under the condition that factor XI, plasma thromboplastin antecedent exists, but it is believed that the factor VIIa sufficient to guarantee of low concentration fully stops blooding.
