Definitions

  • the present invention relates to compositions and methods useful for the modulation (e.g., promotion or inhibition) of angiogenesis and or cardiovascularization in mammals in need of such biological effect.
  • the present invention further relates to the diagnosis and treatment of disorders involving angiogenesis (e.g. , cardiovascular as well as oncological disorders).
  • Angiogenesis defined as the growth or sprouting of new blood vessels from existing vessels, is a complex process that primarily occurs during embryonic development. Under normal physiological conditions in adults, angiogenesis takes place only in very restricted situations such as hair growth and wounding healing (Auerbach,
  • Unregulated angiogenesis has gradually been recognized to be responsible for a wide range of disorders, including, but not limited to cardiovascular disease, cancer, rheumatoid arthritis, psoriasis and diabetic retinopathy (Folkman, 1995, Nat Med 1(1):27-31; Isner, 1999, Circulation 99(13): 1653-5; Koch, 1998,ArthritisRheum4l(6) 951-62; Wahb ⁇ l999, Rheumatology (Oxford) 38(2): ⁇
  • CHF congestive heart failure
  • At least four major compensatory mechanisms are activated in the setting of heart failure to boost cardiac output, including peripheral vasoconstriction, increased heart rate, increased cardiac contractility, and increased plasma volume. These effects are mediated primarily by the sympathetic nervous system and the renin-angiotensin system. See, Eichhorn, American Journal of Medicine, 104: 163-169 (1998). Increased output from the sympathetic nervous system increases vascular tone, heart rate, and contractility.
  • Angiotensin II elevates blood pressure by 1) directly stimulating vascular smooth muscle contraction, 2) promoting plasma volume expansion by stimulating aldosterone and antidiuretic hormone secretion, 3) stimulating sympathetic-mediated vascular tone, and 4) catalyzing the degradation of bradykinin, which has vasodilatory and natriuretic activity. See, review by Brown and Vaughan. Circulation.97: 1411-1420(1998). As noted below, angiotensin II may also have directly deleterious effects on the heart by promoting myocyte necrosis (impairing systolic function) and intracardiac fibrosis (impairing diastolic and in some cases systolic function). See, Weber, Circulation. 96: 4065-4082 (1998).
  • cardiac hypertrophy an enlargement ofthe heart that is activated by both mechanical and hormonal stimuli and enables the heart to adapt to demands for increased cardiac output. Morgan and Baker, Circulation. 83: 13-25 (1991).
  • This hypertrophic response is frequently associated with a variety of distinct pathological conditions such as hypertension, aortic stenosis, myocardial infarction, cardiomyopathy, valvular regurgitation, and intracardiac shunt, all of which result in chronic hemodynamic overload.
  • Hypertrophy is generally defined as an increase in size of an organ or structure independent of natural growth that does not involve tumor formation. Hypertrophy of the heart is due either to an increase in the mass of the individual cells (myocytes), or to an increase in the number of cells making up the tissue (hyperplasia), or both. While the enlargement of an embryonic heart is largely dependent on an increase in myocyte number (which continues until shortly after birth), post-natal cardiac myocytes lose their proliferative capacity. Further growth occurs through hypertrophy ofthe individual cells.
  • Adult myocyte hypertrophy is initially beneficial as a short term response to impaired cardiac function by permitting a decrease in the load on individual muscle fibers. With severe, long-standing overload, however, the hypertrophied cells begin to deteriorate and die.
  • non-myocytes On a cellular level, the heart is composed of myocytes and surrounding support cells, generically called non-myocytes. While non-myocytes are primarily fibroblast/mesenchyrnal cells, they also include endothelial and smooth muscle cells. Indeed, although myocytes make up most ofthe adult myocardial mass, they represent only about 30% ofthe total cell numbers present in heart. In response to hormonal, physiological, hemodynamic, and pathological stimuli, adult ventricular muscle cells can adapt to increased workloads through the activation of a hypertrophic process. This response is characterized by an increase in myocyte cell size and contractile protein content of individual cardiac muscle cells, without concomitant cell division and activation of embryonic genes, including the gene for atrial natriuretic peptide (ANP).
  • APN atrial natriuretic peptide
  • non-myocyte supporting cells may additionally be involved in the development of cardiac hypertrophy, and various non-myocyte derived hypertrophic factors, such as, leukocyte inhibitory factor (LIF) and endothelin, have been identified.
  • LIF leukocyte inhibitory factor
  • Metcalf Growth Factors.
  • cardiac hypertrophy varies depending on the underlying cardiac disease.
  • Catecholamines, adrenocorticosteroids, angiotensin, prostaglandins, LIF, endothelin (including endothelin-1, -2, and -3 and big endothelin), and CT-1 are among the factors identified as potential mediators of hypertrophy.
  • beta-adrenergic receptor blocking drugs e.g., propranolol, timolol, tertalolol, carteolol, nadolol, betaxolol, penbutolol, acetobutolol, atenolol, metoprolol, carvedilol, etc.
  • verapamil have been used extensively in the treatment of hypertrophic cardiomyopathy.
  • the beneficial effects of beta-blockers on symptoms (e.g., chest pain) and exercise tolerance are largely due to a decrease in the heart rate with a consequentprolongation of diastole and increased passive ventricular filling.
  • Nifedipine and diltiazem have also been used occasionally in the treatment of hypertrophic cardiomyopathy. Lorell et al, Circulation. 65: 499-507 (1982); Betocchi et al, Am. J. Cardiol.. 78: 451-457 (1996).
  • nifedipine may be harmful, especially in patients with outflow obstruction.
  • Disopyramide has been used to relieve symptoms by virtue of its negative inotropic properties. Pollick, N. Engl. J. Med..307: 997-999 (1982). In many patients, however, the initial benefits decrease with time. Wigle et al, Circulation. 92: 1680-1692 (1995).
  • Antihypertensive drug therapy has been reported to have beneficial effects on cardiac hypertrophy associated with elevated blood pressure.
  • drugs used in antihypertensive therapy are calcium antagonists, e.g. , nitrendipine; adrenergic receptor blocking agents, e.g., those listed above; angiotensin converting enzyme (ACE) inhibitors such as quinapril, captopril, enalapril, ramipril, benazepril, fosinopril, and lisinopril; diuretics, e.g., chlorothiazide, hydrochloro iazide,hydroflumemazide,memylchlot azide,benzthiazide, dichlorphenamide, acetazolamide, and indapamide; and calcium channel blockers, e.g., diltiazem, nifedipine, verapamil, and nicardipine.
  • ACE angio
  • CHF CHF. Another treatment modality is heart transplantation, but this is limited by the availability of donor hearts.
  • Endothelin is a vasoconstricting peptide comprising 21 amino acids, isolated from swine arterial endothelial culture supernatant and structurally determined. Yanagisawa et al, Nature. 332: 411-415 (1988). Endothelin was later found to exhibit various actions, and endothelin antibodies as endothelin antagonists have proven effective in the treatment of myocardial infarction, renal failure, and other diseases. Since endothelin is present in live bodies and exhibits vasoconstricting action, it is expected to be an endogenous factor involved in the regulation of the circulatory system, and may be associated with hypertension, cardiovascular diseases such as myocardial infarction, and renal diseases such as acute renal failure.
  • Endothelin antagonists are described, for example, in U.S. Pat. No. 5,773,414; JP Pat. Publ. 3130299/1991, EP 457,195; EP 460,679; and EP 552,489.
  • a new endothelin B receptor for identifying endothelin receptor antagonists is described in U.S. Pat. No. 5,773,223.
  • ACE angiotensin-converting enzyme
  • ACE inhibitors have functional class III heart failure.
  • ACE inhibitors An alternative to ACE inhibitors is represented by specific ATI receptor antagonists.
  • Clinical studies are planned to compare the efficacy of these two modalities in the treatment of cardiovascular and renal disease.
  • animal model data suggests that the ACE/Ang II pathway, while clearly involved in cardiac hypertrophy, is not the only, or even the primary pathway active in this role.
  • Mouse genetic "knockout" models have been made to test individual components ofthe pathway. In one such model, the primary cardiac receptor for Ang II, AT sub IA, has been genetically deleted; these mice do not develop hypertrophy when Ang II is given experimentally (confirming the basic success ofthe model in eliminating hypertrophy secondary to Ang II).
  • thrombolytic agents e.g., streptokinase, urokinase, and in particular tissue plasminogen activator (t-PA) have significantly increased the survival of patients who suffered myocardial infarction.
  • t-PA tissue plasminogen activator
  • t-PA may also be administered as a single bolus, although due to its relatively short half-life, it is better suited for infusion therapy. Tebbe et al, Am. J. Cardiol., 64: 448-453 (1989).
  • TNK t-PA a T103N, NI 17Q, KHRR(296-299)AAAA t-PA variant, Keyt et al, Proc. Natl. Acad. Sci. USA.91: 3670-3674 (1994)

  • vascular endothelial cell growth and angiogenesis in many diseases and disorders, it is desirable to have a means of reducing or inhibiting one or more of the biological effects causing these processes. It is also desirable to have a means of assaying for the presence of pathogenic polypeptides in normal and diseased conditions, and especially cancer. Further, in a specific aspect, as there is no generally applicable therapy for the treatment of cardiac hypertrophy, the identification of factors that can prevent or reduce cardiac myocyte hypertrophy is of primary importance in the development of new therapeutic strategies to inhibit pathophysiological cardiac growth. While there are several treatment modalities for various cardiovascular and oncologic disorders, there is still a need for additional therapeutic approaches.

  • cardiovascular, endothelial and angiogenic disorder cardiac, endothelial and angiogenic disorder
  • cardiac, endothelial and angiogenic dysfunction cardiac, endothelial or angiogenic disorder
  • cardiovascular, endothelial or angiogenic dysfunction cardiac, endothelial or angiogenic dysfunction
  • cardiac, endothelial or angiogenic dysfunction refers in part to systemic disorders that affect vessels, such as diabetes mellitus, as well as diseases ofthe vessels themselves, such as ofthe arteries, capillaries, veins, and/or lymphatics. This would include indications that stimulate angiogenesis and or cardiovascularization, and those that inhibit angiogenesis and/or cardiovascularization.
  • Such disorders include, for example, arterial disease, such as atherosclerosis, hypertension, inflammatory vasculitides, Reynaud's disease and Reynaud's phenomenon, aneurysms, and arterial restenosis; venous and lymphatic disorders such as thrombophlebitis, lymphangitis, and lymphedema; and other vascular disorders such as peripheral vascular disease, cancer such as vascular tumors, e.g.
  • hemangioma capillary and cavernous
  • glomus tumors telangiectasia
  • bacillary angiomatosis hemangioendothelioma
  • angiosarcoma haemangiopericytoma
  • Kaposi's sarcoma lymphangioma
  • lymphangiosarcoma tumor angiogenesis
  • trauma such as wounds, bu s, and other injured tissue
  • implant fixation scarring, ischemia reperfusion injury, rheumatoid arthritis
  • cerebrovascular disease renal diseases such as acute renal failure, and osteoporosis.
  • renal diseases such as acute renal failure, and osteoporosis.
  • “Hypertrophy”, as used herein, is defined as an increase in mass of an organ or structure independent of natural growth that does not involve tumor formation. Hypertrophy of an organ or tissue is due either to an increase in the mass ofthe individual cells (true hypertrophy), or to an increase in the number of cells making up the tissue
  • cardiac hypertrophy is defined as an increase in mass of the heart, which, in adults, is characterized by an increase in myocyte cell size and contractile protein content without concomitant cell division.
  • the character ofthe stress responsible for inciting the hypertrophy (e.g., increased preload, increased afterload, loss of myocytes, as in myocardial infarction, or primary depression of contractility), appears to play a critical role in determining the nature ofthe response.
  • the early stage of cardiac hypertrophy is usually characterized morphologically by increases in the size of myofibrils and mitochondria, as well as by enlargement of mitochondria and nuclei.
  • cardiac hypertrophy is used to include all stages ofthe progression of this condition, characterized by various degrees of structural damage ofthe heart muscle, regardless ofthe underlying cardiac disorder. Hence, the term also includes physiological conditions instrumental in the development of cardiac hypertrophy, such as elevated blood pressure, aortic stenosis, or myocardial infarction.
  • Heart failure refers to an abnormality of cardiac function where the heart does not pump blood at the rate needed for the requirements of metabolizing tissues.
  • the heart failure can be caused by a number of factors, including ischemic, congenital, rheumatic, or idiopathic forms.
  • CHF Congestive heart failure
  • Myocardial infarction generally results from atherosclerosis of the coronary arteries, often with superimposed coronary thrombosis. It may be divided into two major types: transmural infarcts, in which myocardial necrosis involves the full thickness ofthe ventricular wall, and subendocardial (nontransmural) infarcts, in which the necrosis involves the subendocardium, the intramural myocardium, or both, without extending all the way through the ventricular wall to the epicardium. Myocardial infarction is known to cause both a change in hemodynamic effects and an alteration in structure in the damaged and healthy zones of the heart.
  • myocardial infarction reduces the maximum cardiac output and the stroke volume of the heart. Also associated with myocardial infarction is a stimulation of the DNA synthesis occurring in the interstice as well as an increase in the formation of collagen in the areas of the heart not affected.
  • cardiac hypertrophy has long been associated with "hypertension".

  • “Stringency” of hybridization reactions is readily determinable by one of ordinary skill in the art, and generally is an empirical calculation dependent upon probe length, washing temperature, and salt concentration. In general, longer probes require higher temperatures for proper annealing, while shorter probes need lower temperatures. Hybridization generally depends on the ability of denatured DNA to reanneal when complementary strands are present in an enviromnent below their melting temperature. The higher the degree of desired homology between the probe and hybridizable sequence, the higher the relative temperature that can be used. As a result, it follows that higher relative temperatures would tend to make the reaction conditions more stringent, while lower temperatures less so.

  • the CDRs in each chain are held together in close proximity by the FR regions and, with the CDRs from the other chain, contribute to the formation of the antigen-binding site of antibodies. See, Kabat et al, NHI Publ, No.91-3242. Vol. I, pages 647-669 (1991).
  • the constant domains are not involved directly in binding an antibody to an antigen, but exhibit various effector functions, such as participation ofthe antibody in antibody-dependent cellular toxicity.
  • Antibody fragments comprise a portion of an intact antibody, preferably the antigen-binding or variable region of the intact antibody.
  • antibody fragments include Fab, Fab', F(ab') 2 , and Fv fragments; diabodies; linear antibodies (Zapata et al. , Protein Eng..8(10): 1057-1062 (1995)); single-chain antibody molecules; and multispecific antibodies formed from antibody fragments.
  • Papain digestion of antibodies produces two identical antigen-binding fragments, called “Fab” fragments, each with a single antigen-binding site, and a residual "Fc” fragment, whose name reflects its ability to crystallize readily. Pepsin treatment yields an F(ab') 2 fragment that has two antigen-combining sites and is still capable of cross-linking antigen.
  • Fv is the minimum antibody fragment that contains a complete antigen-recognition and -binding site. This region consists of a dimer of one heavy- and one light-chain variable domain in tight, non-covalent association. It is in this configuration that the three CDRs of each variable domain interact to define an antigen-binding site on the surface of the V H -V L dimer. Collectively, the six CDRs confer antigen-binding specificity to the antibody. However, even a single variable domain (or half of an Fv comprising only three CDRs specific for an antigen) has the ability to recognize and bind antigen, although at a lower affinity than the entire binding site.
  • the Fab fragment also contains the constant domain of the light chain and the first constant domain (CHI) of the heavy chain.
  • Fab' fragments differ from Fab fragments by the addition of a few residues at the carboxy terminus ofthe heavy chain CHI domain including one or more cysteines from the antibody hinge region.
  • Fab'-SH is the designation herein for Fab' in which the cysteine residue(s) ofthe constant domains bear a free thiol group.

Furthermore, in contrast to conventional (polyclonal) antibody preparations that typically include different antibodies directed against different determinants (epitopes), each monoclonal antibody is directed against a single determinant on the antigen. In addition to their specificity, the monoclonal antibodies are advantageous in that they are synthesized by the hybridoma culture, uncontaminated by other immunoglobulms.
