Definitions

  • the present invention relates to novel vaccine therapies, and prophylactic treatments of atherosclerotic diseases. Accordingly there is provided, immunogens capable of inducing an immune response against specific epitopes of Apolipoprotein C-III (ApoCIII).
  • the vaccines of the present invention comprising said immunogens, are potent in the prevention, or reduction, of atherosclerotic plaque formation over prolonged periods of time, thereby reducing the potential of atherosclerosis leading to coronary or cerebrovascular disease.
  • methods of treating or preventing atherosclerosis by passive vaccination through administration to a patient of an antibody that is capable of binding to the specific fragments of ApoCIII.
  • Specific monoclonal antibodies and their use in therapy of atherosclerosis are provided.
  • the epitopes of ApoCIII which form the basis of the immunogens of the present invention, and also consist of the targets for the passive immunotherapy aspects of the present invention, are encompassed within the regions between amino acid numbers 12-35 and between amino acid numbers 45-76 (particularly 45-65) of the mature form of human ApoCIII.
  • Atherosclerosis is the leading cause of death and disability in the developed world, and is the major cause of coronary and cerebrovascular deaths, with approximately 7.2 and 4.6 million deaths per year worldwide respectively (Atherosclerosis is generally described in Harrison's Principles of Internal Medicine (14 th Edition, McGraw Hill, pl345-1352), Ralph, J.
  • Atherosclerosis of the coronary arteries commonly causes angina pectoris and myocardial infarction.
  • atherosclerosis of the arteries supplying the central nervous system frequently provokes transient cerebral ischemia and strokes.
  • atherosclerosis can cause intermittent claudication and gangrene and can jeopardise limb viability.
  • Involvement of the splanchnic circulation can cause mesenteric ischemia and bowel infarction.
  • Atherosclerosis can affect the kidney directly (eg causing renal artery stenosis), and in addition, the kidney is a frequent site of atheroembolic disease.
  • Atherogenesis in humans typically occurs over many years, usually many decades.
  • the slow build up of athero genie plaques in the lining of the vasculature can lead to chronic clinical expressions through blood flow restriction (such as stable effort-induced angina pectoris or predictable and reproducible intermittent claudication).
  • a much more dramatic acute clinical event such as a myocardial infarction or cerebrovascular accident can occur after plaque rupture.
  • the way in which atherosclerosis affects an arterial segment also varies, an additional feature of the heterogeneity and complexity of this disease.
  • Atheromas are usually thought of as stenotic lesions, or plaques, which can limit blood flow, however, atherosclerosis can also cause ectasia and development of aneurysmal disease with an increase in lumen caliber. This expression of atherosclerosis frequently occurs in the aorta, creating a predisposition to rupture or dissection rather than to stenosis or occlusion.
  • LDL Low-density lipoprotein
  • oxidised and glycated lipoproteins then contribute to many of the subsequent events of lesion development.
  • the chemical modifications attract macrophages within the vessel walls, which internalise the oxidised LDL and become foam cells which initiate lesions called plaques.
  • plaques It is the atherosclerotic plaques which are responsible for the clinical manifestations of atherosclerosis, either they limit blood flow, or allow aneurism, or may even rupture provoking the coronary or cerebrovascular attacks.
  • the development of atherosclerosis is a long process which may occur over decades, which is initiated by an imbalance between atherogenic and protective lipoproteins.
  • cholesterol associated with high-density lipoproteins or HDL serum and low-density lipoproteins or LDL (so called “bad” cholesterol) levels in the circulation are thought to be markers of increased probability of atherosclerosis (Harrison's Principles of Internal Medicine (14 th Edition, McGraw Hill, pl345-1352)).
  • Cholesterol, cholesterol esters, triacylglycerols and other lipids are transported in body fluids by a series of lipoproteins classified according to their increasing density: chylomicrons, Very Low, Low, Intermediate and High density lipoproteins (CM, VLDL, LDL, IDL and HDL respectively). These lipoprotein-complexes consist of a core of hydrophobic lipids surrounded by polar lipids and then by a shell of
  • Apolipoproteins There are at least twelve types of apolipoproteins known, A-I, A-II, A-IV, A-V, B, CI, CII, CIII, D, E, H and J. There are at least two functions of these apolipoproteins which are common to all lipoprotein complexes, first they are responsible for the solubilisation of the hydrophobic lipid cores that they carry, and second they are also involved in the regulation of cholesterol lipoprotein uptake by specific cells.
  • the different types of lipoproteins may have different functions, for example LDL (which are rich in cholesterol esters) are thought to be associated with the transport of cholesterol to peripheral tissues for new membrane synthesis.
  • apolipoprotein C-III is a 79 amino acid protein produced in the liver and intestine (Brewer et al., J. Biol. Chem. (1974), 249 : 4975-4984; Protter, A.A., et al., 1984, DNA, 3:449-456; Frachart, J.C. et al, 1996, Drugs Affecting Lipid Metabolism, (Eds. Gotto, A.M. et al.), Kluwer Academic Publishers and Fordazione Giovanni Lorenzini, Netherlands, p631-638; Claveny, V.
  • Apo CIII is a component of CM, VLDL, LDL (Lenich et al., 0,., J. Lip. Res. (1988) 29, 755-764), and also HDL, and exists as three isoforms : apo CIII0, apo CIII1 and apo CIII2.
  • Apo CIII0 is not glycosylated, however apo CIII1 and apo CIII2 are glycosylated and have respectively one and two sialic acid residues (Ito et al., 1989 J.lipd. Res. Nov 30:11 1781-1787).
  • the sugar moiety consists of disaccharide ⁇ - D galactosyl (1-3) ⁇ -N-Acetyl-D-Galactosamine attached to threonine 74 of protein chain by O-glycosidic binding (Assman et al, 1989, BBA 541 :234-240).
  • apo C ⁇ iO In human normolipidemic plasma apo C ⁇ iO, apo CIII1 and apo CIII2 represent 14%, 59% and 27% of total apo CIII respectively. Mutagenesis of the glycosylation site of human apo CIII doesn't affect its secretion and lipid binding (Roghani et al., 1988 JBC 34:17925-32).
  • Mature Human ApoCIII has the following amino acid sequence: iSEAEDASLLSFMQGYMKHATKTAKDALSSVQESQVAQQARGWVTDGFSSL KDYWSTVKDKFSEFWDLDPEVRPTSAVAA 79 (SEQ ID.NO. 1).
  • Plasma concentration of apo CIII is positively correlated with levels of plasma triglycerides (Schonfeld et al, Metabolism (1979) 28 : 1001-1010; Kaslyap et al, J. Lip. Res. (1981) 22 : 800-810). Liver perfusion studies demonstrate that apo CIQ inhibits the hepatic uptake of triglyceride-rich lipoproteins (TRL) and their remnants (Shelburne et al, J. Clin. hives., (1980) 65 : 652-658, Windier et al, J. Lip. Res.

  • Atherosclerosis may be prevented or ameliorated by active or passive immunotherapy, by reducing or blocking the function of ApoCIII.
  • the active or passive immunotherapies of the present invention can be advantageously carried out using epitopes of ApoCIII.
  • the use of peptides of ApoCIII comprising useful epitopes can focus the immune response to parts of the human ApoCIII molecule without triggering a general response to the whole molecule.
  • this can not only reduce non-preventative immune reactions against human ApoCIII, it can also be used as a means of distinguishing parts of ApoCIII that are surface exposed on LDL and not HDL, thus focusing the immune response against carriers of "bad cholesterol", whilst not effecting the positive role of ApoCIII in HDL.
  • the active or passive immunotherapies of the present invention target an epitope found within the region between amino acid number 12 and 35, or an epitope found within the region between amino acids 45 and 76 of the human ApoCIII molecule as it exists in the circulation of a human, in addition it is preferred that the immunotherapy targets the epitope that is found within the region between amino acid 12 to 21 or 45 to 65 of human ApoCIII.

Abstract

La présente invention se rapporte à de nouvelles thérapies vaccinales et à des traitements prophylactiques de maladies artériosclérotiques. On prévoit des immunogènes contenant des fragments ou dérivés spécifiques de l'Apolipoproteine C-III (ApoCIII). Les vaccins de cette invention, renfermant les immunogènes, sont puissants en terme de prévention, ou de réduction, de la formation de plaque artériosclérotique sur des périodes prolongées, ce qui a pour effet de réduire le risque que l'artériosclérose n'entraîne des maladies coronaires ou cérébrovasculaires. Font également l'objet de cette invention des méthodes de traitement ou de prévention de l'artériosclérose par vaccination active, ou vaccination passive, au moyen d'administration à un patient d'un anticorps apte à se lier à des fragments spécifiques de ApoCIII. Des anticorps monoclonaux spécifiques et leur utilisation dans la thérapie de l'artériosclérose font également l'objet de cette invention. L'invention concerne par ailleurs l'utilisation des immunogènes de cette invention dans le domaine médical, et leurs procédés de production. Les fragments d'ApoCIII formant la base des immunogènes de cette invention ainsi que les cibles d'immunothérapie passive se trouvent au sein des zones entre les nombres 45-76 d'acides aminés et, plus particulièrement, entre 12-35 de la forme adulte de l'ApoCIII humaine.
