Definitions
- the present invention relates to stents containing blood coagulation factor Xa, processes for producing these stents and their use, in particular for the treatment and / or prophylaxis of thromboses and / or restenoses.
- Atherosclerotic coronary diseases are treated, among other things, with the now common method of percutaneous transluminal coronary angioplasty (PTCA).
- PTCA percutaneous transluminal coronary angioplasty
- a balloon catheter is inserted into the narrowed or closed
- the risk of acute restenosis can be reduced by adding platelet aggregation inhibitors.
- the coronary wall can be mechanically supported by a usually cylindrical and expandable braid (stent) which is introduced into the diseased vessel and deployed at the site of the stenosis in order to open the narrowed area and to keep it open by supporting the blood vessel wall , Even if this method can slightly reduce the risk of restenosis, there is currently no convincing therapy available for subacute restenosis.
- Anticoagulants such as heparin are currently used; Platelet aggregation inhibitors such as, for example, aspirin, clopidogrel (Plavix) or ticlopidine (ticlid); or glycoprotein III / ⁇ ia antagonists such as, for example, abciximab, are used systemically in stent treatment.
- Platelet aggregation inhibitors such as, for example, aspirin, clopidogrel (Plavix) or ticlopidine (ticlid); or glycoprotein III / ⁇ ia antagonists such as, for example, abciximab, are used systemically in stent treatment.
- a more recent option for treating restenosis is to administer the active ingredient locally by means of a stent which releases the active ingredient.
- the combination of Active ingredient and stent enable drug treatment and mechanical stabilization in one application.
- stents with anticoagulants enables a high local concentration of active ingredient without the undesirable systemic side effects (e.g. bleeding or stroke).
- stents can be coated with coating materials containing active ingredient.
- the active ingredient is released by diffusion from the paint or by degradation of the paint when using biodegradable paint systems.
- drug-containing stents can be melted by embedding the drug in a polymeric carrier e.g. with the help of injection molding processes.
- the active ingredient is usually released by diffusion.
- Blood coagulation factor Xa inhibitors are particularly suitable as active substances for the treatment and / or prophylaxis of thromboses and restenoses after the PTCA.
- the blood coagulation factor Xa plays a role in the proliferation of vascular smooth muscle cells (VSMC, vascular s ooth muscle cells).
- VSMC vascular smooth muscle cells
- the migration and proliferation of VSMC due to an injury to the endothelium and the resulting formation of a neointima mainly contribute to the formation of restenosis and atherosclerosis in. Platelets, thrombi and other components of the thrombotic process are important factors in the formation of neointima.
- the serine protease thrombin the formation of which is modulated by the blood coagulation factor Xa, has, in addition to its effect in the plasma coagulation system, further cell effects via its specific receptor. Through this mechanism, it activates platelets and acts as a strong mitogen for endothelial cells, VSMC, connective tissue cells and macrophages.
- the mitogenic effect of the blood coagulation factor Xa occurs indirectly via the platelet-based growth factor (PDGF)
- Receptor tyrosine kinase pathway and leads to the activation of the mitogen-activated protein kinases (MAPK, mitogen-activated protein kinases), which are intracellular mediators of cell proliferation.
- MAPK mitogen-activated protein kinases
- VSMC proliferation modulated by the blood coagulation factor Xa influences the reclosure of vessels and the restenosis after angioplasty.
- intimal hyperplasia after vascular endothelial damage and thus the restenosis rate after successful angioplasty can be reduced by reducing the mitogenic effects of blood coagulation factor Xa itself and / or by reducing the formation of the potent mitogen thrombin ( MM Samama, JM Walenga, B. Kaiser, J. Fareed, Specific Factor Xa Inhibitors, in: M. Verstraete, V. Fuster, EJ Topol (ed.), Cardiovascular Thrombosis: Thrombocardiology and Thromboneurology, Philadelphia 1998, pp. 175- 176).
