Definitions

  • the present invention relates to the use of a plasminogen activator for the treatment of pulmonary disorders .
  • Pulmonary disorders are often life-threatening conditions complicating a number of underlying predisposing disease states.
  • mortality rate has remained high, reportedly above 50% (1,2) .
  • phar acologic regimes has been recommended, a recent review suggests a limited success in most approaches
  • RDS respiratory distress syndrome
  • RDS- HMD respira- tory distress syndrome-hyaline membrane disease
  • ARDS adult respiratory distress syndrome
  • septic shock septic shock
  • ARDS septic shock
  • 3-5 a substantial amount of literature, which, however, did not have any impact on presently recommended treatment regimes of ARDS (3-5) .
  • the alveolar space is without obstructing fibrin, and studies on normal bronchoalveolar lavage have demonstrated considerable amounts of active plasminogen activators, primarily of the urokinase type (6,7).
  • bronchoalveolar lavage of ARDS patients is characterized by multiple haemostatic abnormalities, including increased concentrations of procoagulant factors, high concentration of fibrinolytic inhibitors and no or only traceable fibrinolytic activity (6-9) . It has been demonstrated that ARDS is associated with micro-vascular injury causing microvascular thrombosis and accumulation of a protein-rich fluid containing coagulation factors in the extravascular space (7-12). Because of an excessive inhibition of alveolar fibrinolysis in ARDS, this may ultimately lead to formation of alveolar fibrin.
  • Hardaway and co-workers have previously administrated intravenous urokinase and tissue plasminogen activator in order to prevent ARDS in pigs (13) .
  • Jaques and co-workers have reported on healthy human subjects' inhalation of a heparin aerosol from an ultrasonic nebulizer with mask (14) .
  • Ambrus and Ambrus treated infants who had developed severe RDS with human urokinase activated plasmin intravenously in a four hour infusion and human urokinase activated plasmin by aerosol (15) . Harke has reported the endoscopic removal of blood clottings in the bronchial system due to post bleeding following tonsillectomia .
  • streptokinase was installated endoscopically in the lungs (16) .
  • the intravenous administration of urokinase, tissue plasminogen activator, and plasmin is a non-specific systemic treatment which may activate fibrinolysis anywhere in the body, also in areas where fibrinolyse is not wanted.
  • the administrated thrombolytic agents will attack the thrombosis from the face of the lung pointing toward the body not from the lung side. Since it is believed that it is the presence of the fibrin in the alveolar space that is crucial for the prognosis it takes more time before the symptoms are alleviated due to the fact that digestion of the thrombosis happens from the blood side .
  • an aerosol comprising plasmin may be detrimental to the patient as plasmin is an active unspecific serine protease digesting not only fibrin but also other proteinous items in the lungs.
  • the present invention aims at suggesting a new method for the treatment of pulmonary disorders without the above drawbacks .
  • the new method provides for local and relatively quick treatment of a pulmonary disorder caused by or related to the presence of fibrin by the production of plasmin in si tu through the action of a plasminogen activator.
  • the present invention relates to the use of a plasminogen activator for the manufacture of a pharmaceutical composition for pulmonary administration as an aerosol for the treatment of pulmonary disorders caused by or related to the presence of fibrin.
  • pulmonary administration means administration to one or both lungs.
  • the aerosol may be administrated through the oral, intra- nasal or intratracheal route.
  • pulmonary disorder refers herein to any abnormality in the functioning of the lung, which is caused by or related to the presence of fibrin. Examples of such disorders are RDS, RDS-HMD, ARDS, septic shock, and pneumonia.
  • the plasminogen activator is believed to be carried by the droplets of the aerosol to the relevant sites of the lungs, where the droplets are deposited.
  • the size of the droplets determines the area of the lung, wherein they are predominately deposited.
  • the physician may design the droplet size to reach the target areas of the lungs.
  • the fibrin is deposited in the alveoles.
  • the size of the droplets is designed to carry the droplets all the way through the bronchial tree before deposition.
  • the size of the droplets should preferably be in the range of 2-8 ⁇ m. If the droplets are to be deposited in the bronchial tree, the size should preferably be in the range of 10- 16 ⁇ m.
  • plasminogen activator Any suitable plasminogen activator may be used.
  • Preferred plasminogen activators are selected among the group consisting of streptokinase, urokinase, tissue type plasminogen activator (t-PA) , recombinant tissue type plasminogen activator (rt-PA) , anisoylated plasminogen activator complex (APSAC) , single-chain urokinase plasminogen activator (SCUPA) , or combinations thereof.
  • a plasminogen activator which has fibrin affinity in order to be able to promote the conversion of plasminogen to plasmin.
  • the fibrin specific properties of the plasminogen activator leads to the formation of plasmin only in such areas wherein the plasmin is required. Thus, the potential detrimental effects of the presence of plasmin in areas not involved in the deposition of fibrin are avoided.
  • the affinity to fibrin also means that the generation of significant amounts of plasmin is slowed down when fibrin is digested.
  • a plasminogen activator requiring fibrin as a co-factor is i.a. rt-PA (17, 18).
  • Another plasminogen activator with fibrin specific properties is SCUPA (19) .
  • plasminogen activators e.g. t-PA and SCUPA
  • the non-genuine plasminogen activators may be regarded as non-self by the immunological system and a harmful immunological response may evolve in the lungs.
  • plasminogen activator as an aerosol to the lungs may provide for the destruction of the fibrin deposited within the lung
  • a pharmaceutical composition comprising a plasminogen activator intravenously.
  • the activation of plasmin in the blood will lead to the digestion of an obstructing micro-thrombosis in the blood vessels.
  • plasminogen activator is co-administrated intravenously, the thrombosis will be attacked not only from the lung side but also from the blood side.
  • the intravenously administrated plasminogen activator may be given in any appropriate amount, e.g. in an amount of 5-100 mg/dosage, preferably 10-40 mg/dosage .
  • thrombin which may be inhibited by a heparinoid, e.g. heparin, or a thrombin inhibitor, e.g. hirudin or antithrombin.
  • a heparinoid e.g. heparin or a thrombin inhibitor, e.g. hirudin or antithrombin is administrated simultaneously or subsequent to the plasminogen activator.
  • the agents for preventing further deposits of fibrin are preferably administrated as an aerosol, e.g. in an amount of 5,000-50,000 IU/24 h, preferably
  • the administration may take place as continuous inhaltion of the agent.
  • the pharmaceutical composition for pulmonary administration as an aerosol may be of the solid or the liquid type. If the pharmaceutical composition is of the solid type, the aerosol contains solid particles, which are administrated to the patient. If the pharmaceutical composition is of the liquid type, the plasminogen activator is typically dissolved in an aqueous medium, e.g. an isotonic solution.
  • the amount of administrated plasminogen activator depends on a number of factors, such as the severity of the disorder, the condition, file history, age, sex ect . of the patient.
  • the amount of plasminogen activator in a dosage may be in the range of 5-300 mg, preferably 10-60 mg .
  • a single administration should be sufficient, however, the treatment may be repeated or administrated continously, if desired.
  • the effect of the pulmonary administration of a plasminogen activator, as an aerosol, to a patient in need thereof is visible within hours.
  • the condition of the patient is rapidly improved, which is shown by the rapid decline in the demand for oxygen supply.
  • the case study reported in the following example shows that the demand for oxygen supply (FIO 2 ) declined from 0.85 to 0.40 within 5 hours.
  • the plasminogen activator containing solution may be nebulized according to any technique known in the art. If the patient is connected to a respirator, it may be convenient to nebulize the solution through the nebulizing means of the respirator. If the pulmonary disorder occurs in remote geographical areas or during war actions, the solution may be nebulized through a handy device.
  • the present invention also comprises a device for pulmonary administration of a pharmaceutical composition as an aerosol, wherein the device is provided with a container containing a liquid solution of a plasminogen activator and means for nebulizing the liquid solution.
  • Chest roentgenogram demonstrated bilateral infiltrations of the lungs, probably caused by aspiration. Due to respiratory insufficiency the patient was intubated and volume controlled ventilation was initi- ated with a Servo 900 C respirator (Siemens Elema, Sweden) applying a FIO2 of 0.4. The patient was treated with antibiotics, forced alkalinized diuresis, intravenous Acetylcystein (Muccocyst ® ) 600 mg per day, and as thrombo-prophylaxis subcutaneous Tinzapa ⁇ n (Innohep ® ) 3,500 anti X a units once per day.
