BACKGROUND

In the United States, heart disease is the leading cause of death in both men and women. Several causative factors are implicated in the development of cardiovascular disease including hereditary predisposition to the disease, gender, lifestyle factors such as smoking and diet, age, hypertension, and hyperlipidemia, including hypercholesterolemia. Several of these factors, particularly hyperlipidemia and hypercholesteremia (high blood cholesterol concentrations) provide a significant risk factor associated with atherosclerosis.

Atherosclerosis is associated with an inflammatory response caused by the accumulation of low-density lipoprotein (LDL) molecules in blood vessels. It can be asymptomatic for years. Atherosclerosis causes hardening and narrowing of blood vessels. There are several treatments for atherosclerosis, such as lifestyle change, medication and medical procedures. Statins are a well-known treatment for atherosclerosis. Statins have proven to reduce cardiac risk however the withdrawal of statin therapy abrogrates the protective effect (Heeschen et al. Circulation. 105:1446-1452, 2002).

The current approach to treating atherosclerosis is to provide earlier intervention and life-long treatment. This approach is problematic as it requires identifying asymptomatic patients early in their life cycle and, since risk increases with age, maintaining therapy for the duration of their life. Further, the most efficacious currently available therapies are unable to prevent major cardiac events in all patients whether as primary or secondary interventions. Therefore, there is a need for therapies that can provide rapid benefit in reducing atherosclerosis and have long-term effects that do not require constant administration. The compositions and methods disclosed herein provide an atherosclerosis therapy with sustained therapeutic effects even after the treatment is withdrawn.

A residue of a chemical species, as used in the specification and concluding claims, refers to the moiety that is the resulting product of the chemical species in a particular reaction scheme or subsequent formulation or chemical product, regardless of whether the moiety is actually obtained from the chemical species. Thus, an ethylene glycol residue in a polyester refers to one or more —OCH₂CH₂O— units in the polyester, regardless of whether ethylene glycol was used to prepare the polyester. Similarly, a sebacic acid residue in a polyester refers to one or more —CO(CH₂)₈CO— moieties in the polyester, regardless of whether the residue is obtained by reacting sebacic acid or an ester thereof to obtain the polyester.

“Peptide” as used herein refers to any peptide, oligopeptide, polypeptide, gene product, expression product, or protein. A peptide is comprised of consecutive amino acids. The term “peptide” encompasses naturally occurring or synthetic molecules.

As used herein, the term “Apo E mimetic” is interchangeable with apolipoprotein-E mimicking peptide. Apo E mimetics are peptides that are related to, characteristic of, or mimic Apo E. Apo E mimetics include Apo E peptides (i.e. peptides derived from full length Apo E).

As used herein, “reverse oriented”, “reversed orientation”, “reverse analog” or “reverse sequence” refers to a peptide, or a portion of the peptide, has a reverse amino acid sequence as compared to a non-reverse oriented peptide (i.e., the original sequence is read (or written) from right to left). For example, if one peptide has the amino acid sequence ABCDE, its reverse analog or a peptide having its reverse sequence is as follows: EDCBA. In a dual domain peptide for example, Ac-hE-18A-NH2, either the hE sequence is read from right to left or the 18A sequence is read from right to left. For a reverse analog of, LRKLRKRLLR-DWLKAFYDKVAEKLKEAF (SEQ ID NO:1) can be RLLRKRLKRL-DWLKAFYDKVAEKLKEAF (SEQ ID NO:2) or LRKLRKRLLR-FAEKLKEAVKDYFAKLWD (SEQ ID NO:3).

For example, the peptide 18A-hE is exemplary of a domain switched peptide.

As used herein, “scrambled” “scrambled version”, or “scrambled peptide” is meant to mean that the composition of the amino acid sequence is the same as the unscrambled peptide, however the sequence of the amino acids is altered thus rendering the peptide unable to form either an α-amphipathic helix or does not possess lipid associating (or HSPG associating) properties. However, in some cases, as described in this invention, the scrambled peptide remains able to form a different helical structure, such as a i-helix. For example, if one peptide has the amino acid sequence ABCDE, the scrambled version of the peptide could have the amino acid sequence DEABC. Scrambled peptides are often denoted as having a “Sc” prior to the portion of the peptide that is scrambled. For example, Sc-hE-18A denoted that the hE portion of the peptide is scrambled.

As used herein, “sample” is meant to mean an animal; a tissue or organ from an animal; a cell (either within a subject, taken directly from a subject, or a cell maintained in culture or from a cultured cell line); a cell lysate (or lysate fraction) or cell extract; or a solution containing one or more molecules derived from a cell or cellular material (e.g. a polypeptide or nucleic acid), which is assayed as described herein.

Another example can be a six month treatment cycle followed by a six month rest phase and then a three month treatment cycle followed by a one year rest phase.

“Dose” or “dosage” as used herein refers to a specific quantity of a therapeutic agent, such as an Apo E mimetic, that is taken at specific times.

As used herein, “treat” is meant to mean administer one of the disclosed compositions to a subject, such as a human or other mammal (for example, an animal model), that has atherosclerosis, in order to prevent or delay a worsening of the effects of the disease or condition, or to partially or fully reverse the effects of the disease.

As used herein, “prevent” is meant to mean minimize the chance that a subject who has an increased susceptibility for developing atherosclerosis will develop atherosclerosis.

As used herein, the term “treatment cycle” refers to the administration of Apo E mimetics for an established period of time. A treatment cycle includes a wide range of dosages of Apo E mimetics as well as different lengths of time for administering the Apo E mimetics. For example, a treatment cycle can be a three month period wherein an Apo E mimetic is administered twice a week for the three month period.

As used herein, “effective amount” is meant to mean a sufficient amount of the composition or Apo E mimetic to provide the desired effect. For example, an effective amount of an Apo E mimetic can be an amount that provides a therapeutic affect and provides sustained therapeutic effects after withdrawal of the treatment. An effective amount of an Apo E mimetic is an amount that is able to cause a benefit illustrated by a decrease in atherosclerosis, a decrease in artery wall stiffness, a decrease in isolated systolic hypertension, a decrease in arterial inflammation, an increase in anti-oxidant capability of the HDL fraction and/or an improvement in myocardial function, as well as an amount that allows for a sustained therapeutic effect after withdrawal of the Apo E mimetic. The exact amount required will vary from subject to subject, depending on the species, age, and general condition of the subject, the severity of disease (or underlying genetic defect) that is being treated, the particular compound used, its mode of administration, and the like. Thus, it is not possible to specify an exact “effective amount.” However, an appropriate “effective amount” may be determined by one of ordinary skill in the art using only routine experimentation.

As used herein, “sustained therapeutic effect” is a therapeutic effect that persists after the therapeutic has been withdrawn. For example, the sustained therapeutic effect is maintained even after the acute cholesterol lowering effect is gone.

“Rest phase” as used herein refers to a period of time wherein an Apo E mimetic is not administered.

“Atherosclerotic burden” as used herein is the amount of atherosclerosis in the arteries of a patient. This may include the coronary, carotid, peripheral and other arteries. The atheroma may be complex lesions with a smooth muscle and collagen containing fibrous cap, areas of calcification, cholesterol crystals and cholesterol laden macrophages (foam cells) and/or less complex and more unstable lesions with less calcification and a thinner fibrous cap, and more foam cells and cholesterol (unstable lesions). The unstable lesions may intrude into the lumen of the artery or expand away from the lumen of the artery.

The phrase “lipid disorder” is meant to mean when a subject has an excess of lipids or increased inflammatory lipids in their blood. Lipids include, but are not limited to lipids such as ox-LDL (i.e., oxidized PAPC (1-palmitoyl 2-arachidonyl phophyatidyl choline)). Oxidation of PAPC or PLPC, the lipid components of LDL, produce oxidized lipids. Having a lipid disorder can make one more likely to develop inflammatory disease such as atherosclerosis and heart disease. Lipid disorders can be caused by genetic predispositions or diet.

As used herein, “lipoprotein” or “lipoproteins” is meant to mean a biochemical assembly that contains both proteins and lipids. The lipids or their derivatives may be covalently or non-covalently bound to the proteins. Many enzymes, transporters, structural proteins, antigens, adhesins, and toxins are lipoproteins. Examples include the high density and low density lipoproteins of the blood, the transmembrane proteins of the mitochondrion and the chloroplast, and bacterial lipoproteins

As used herein, “high-density lipoprotein” (HDL) is meant to mean a class of lipoproteins, varying somewhat in their size (8-11 nm in diameter), that can transport cholesterol. HDL cholesterol is cholesterol that is associated with HDLs. About one-fourth to one-third of blood cholesterol is carried by high-density lipoprotein (HDL). HDL cholesterol is known as “good” cholesterol, because high levels of HDL seem to protect against heart attack. Low levels of HDL (less than 40 mg/dL in men and less than 50 mg/dL in women) also increase the risk of heart disease. Medical experts think that HDL tends to carry cholesterol away from the arteries and back to the liver, where it is passed from the body. Some experts believe that that HDL removes excess cholesterol from arterial plaque, thus slowing its buildup

As used herein, “very Low Density Lipoproteins” (VLDL) is meant to mean a lipoprotein subclass. It is assembled in the liver from cholesterol and apolipoproteins. It is converted in the bloodstream to low density lipoprotein (LDL). VLDL particles have a diameter of 30-80 nm. VLDL transports endogenous products where chylomicrons transport exogenous (dietary) products.

As used herein, “low-density lipoprotein” or “LDL” is meant to mean a lipoprotein that varies in size (approx. 22 nm) and can contain a changing number of triglycerides and cholesteryl esters they actually have a mass and size distribution. Each native LDL particle contains a single apolipoproteinB-100 molecule (Apo B-100, a protein with 4536 amino acid amino acid residues) and a phospholipid coat that circles the triglycerides and cholesteryl esters, keeping them soluble in the aqueous environment. LDL is commonly referred to as bad cholesterol. LDL cholesterol is cholesterol that is associated with LDLs. When too much LDL cholesterol circulates in the blood, it can slowly build up in the inner walls of the arteries that feed the heart and brain. Together with other substances, it can form plaque, a thick, hard deposit that can narrow the arteries and make them less flexible. This condition is known as atherosclerosis. If a clot forms and blocks a narrowed artery, then heart attack or stroke can result.

Cholesterol cannot dissolve in the blood. It has to be transported to and from the cells by carriers called lipoproteins. LDLs and HDLs along with triglyceride-rich lipoproteins (VLDL) and Lp(a) cholesterol, make up your total cholesterol count, which can be determined through a blood test.

The phrase “nucleic acid” as used herein refers to a naturally occurring or synthetic oligonucleotide or polynucleotide, whether DNA or RNA or DNA-RNA hybrid, single-stranded or double-stranded, sense or antisense, which is capable of hybridization to a complementary nucleic acid by Watson-Crick base-pairing. Nucleic acids of the invention can also include nucleotide analogs (e.g., BrdU), and non-phosphodiester internucleoside linkages (e.g., peptide nucleic acid (PNA) or thiodiester linkages). In particular, nucleic acids can include, without limitation, DNA, RNA, cDNA, gDNA, ssDNA, dsDNA or any combination thereof

Apolipoprotein E-mimicking peptides have both direct cholesterol lowering effects by providing an alternative ligand for receptors on the liver to clear atherogenic Apolipoprotein B containing lipoproteins (LDL, VLDL, and β-VLDL), and direct beneficial effects on the artery wall. New, more effective methods of imaging coronary atherosclerosis allow for direct measurement of benefits to the artery wall (Van Velzen, et al. Hellenic J Cardiol 50: 245-263, 2009). The Apo E-mimicking peptides can enhance the removal of cholesterol from the artery wall, working in conjunction with HDL, increasing the formation of lipid poor preβ-HDL that accept cholesterol from macrophages. The Apo E-mimicking peptides can stimulate macrophage-mediated clearance of dead and dying cells in the artery wall (efferocytosis), improve the quality of HDL by increasing PON-1 levels and bringing down plasma lipid hydroperoxide levels, decrease macrophage content in atherosclerotic lesions resulting in more stable lesions, and decrease inflammation in the artery wall. As a result, the Apo E-mimicking peptides reduce the size of atherosclerotic lesions more rapidly than apoA-I mimetic peptides and more rapidly than the statins (HMG-CoA reductase inhibitors). Atherosclerotic lesion regression persists in Apo E-mimicking peptides treated animals even when cholesterol levels are the same as in saline treated animals. Thus, the effects cannot be simply explained by cholesterol lowering.

1. Apolipoprotein E

Apolipoprotein E (Apo E) plays an important role in the metabolism of triglyceride-rich lipoproteins, such as very low density lipoprotein (VLDL) and chylomicrons. Apolipoprotein E mediates the high affinity binding of Apo E-containing lipoproteins to the low density lipoprotein (LDL) receptor (Apo B, E receptor) and the members of its gene family, including LDL receptor related protein (LRP), very low density lipoprotein receptor (VLDLR) and the Apo E2 receptor (Apo E2R) (Mahley, R. W., (1988) Science 240, 622-630). The putative and complex role of Apo E in atherosclerosis has been emphasized by several observations: (i) mice that over express human Apo E have lower levels of total plasma cholesterol levels (Shimono, H. N., et al., (1992) Eur. J. Clin. Invest. 90, 2084-2991), (ii) intravenous injection of human Apo E into cholesterol-fed rabbits protects these animals from atherosclerosis (Yamada, et al., (1989) Proc. Natl. Acad. Sci. U.S.A. 86, 665-669), and (iii) loss of the Apo E gene in mice produces spontaneous atherosclerosis (Zhang, S. H., et al., (1992) Science 258, 468-471) which is ameliorated when macrophage-specific apo E expression is initiated in Apo E-deficient mice (Spangenberg, J., et al., (1997) Biochem. Biophys. Acta 1349, 109-121).

Apo E is a protein that binds lipid and has two major domains (Mahley, R. W., et al. J. Lipid Res. 1999, 40:622-630). The 22 kDa amino terminal domain has been shown by X-ray crystallographic studies to be a 4-helix bundle (Wilson, C., et al. Science 1991; 252:1817-1822) and to contain a positively-charged receptor binding domain. For this region to mediate very low-density lipoprotein (VLDL) binding to its receptors, the apolipoprotein must associate with the lipoprotein surface; this is enabled by the C-terminal amphipathic helical region. If the 4-helix bundle that contains the positively charged receptor-binding domain does not open up on the lipoprotein surface, then the VLDL is defective in binding to receptors. Thus, the positively charged arginine (Arg)-rich cluster domain of the Apo E and the C-terminal amphipathic helical domain, are both required for the enhanced uptake of atherogenic Apo E-containing lipoproteins.

Apo E is secreted as a 299 amino acid residue protein with a molecular weight of 34,200. Based on thrombin cleavage of Apo E into two fragments, a two-domain hypothesis was initially suggested to explain the fact that the C-terminal region of Apo E (192-299) is essential for its binding to hypertriglyceridemic VLDL and the N-terminal 22 kDa domain (1-191), binds to the LDL-R (Bradley, W. A., et al., (1986) J. Lipid Res. 27, 40-48). Additional physical-chemical characterization of the protein and its mutants have extended this concept and have shown that the region 192-211 binds to phospholipid while the amino terminal domain (1-191) is a globular structure that contains the LDL receptor binding domain in the 4-helix bundle (Wilson, C., et al., (1991) Science 252, 1817-1822). Studies with synthetic peptides (Sparrow et al. Biochemistry 31(4):1065-8, 1992) and monoclonal antibodies pinpointed the LDL receptor binding domain of apo E between residues 129-169, a domain enriched in positively charged amino acids, Arg and Lys (Rall, S. C., Jr., et al., (1982) PNAS USA 79, 4696-4700; Lalazar, A., et al., (1988) J. Biol. Chem. 263, 3542-2545; Dyer, C. A., et al., (1991) J. Biol. Chem. 296, 22803-22806; and Dyer, C. A., et al., (1991) J. Biol. Chem. 266, 15009-15015).

To test the hypothesis that a minimal arginine-rich Apo E receptor binding domain (141-150) was sufficient to enhance low density lipoprotein (LDL) and very low density lipoprotein (VLDL) uptake and clearance when covalently linked to a class A amphipathic helix, a peptide was synthesized in which the receptor binding domain of human Apo E, LRKLRKRLLR (SEQ ID NO:4) (hApo E[141-150] also referred to as “hE”), was linked to 18A, a well characterized high affinity lipid-associating peptide (DWLKAFYDKVAEKLKEAF (SEQ ID NO:5), also referred to as “18A”) to produce a peptide denoted as hApo E[141-150]-18A (also referred to as “hE-18A”) (see U.S. Pat. No. 6,506,880, which is hereby incorporated by reference in its entirety for its teaching of specific Apo E mimetics and their uses). Also synthesized was an end protected analog of hE-18A, denoted Ac-hE18A-NH2. The importance of the lysine residues and the role of the hydrophobic residues in the receptor binding domain were also studied using two analogs, LRRLRRRLLR (SEQ ID NO:11)-18A (also referred to as “hE(R)-18A”) and LRKMRKRLMR (SEQ ID NO:7)-18A (also referred to as “mE18A”), whereby the receptor binding domain of human Apo E was modified to substitute arginine (R) residues for lysine (K) residues at positions 143 and 146 (LRRLRRRLLR; SEQ ID NO:11) and whereby the receptor binding domain of mouse Apo E (LRKMRKRLMR; SEQ ID NO:7), were linked to 18A, respectively. The effect of the dual character peptides on the uptake and degradation of human LDL/VLDL by cells was then determined.

It was determined that in MEF 1 cells with induced LDL receptors, LDL internalization was enhanced three, five and seven times by Ac-mE-18A-NH₂, Ac-hE-18A-NH₂, and Ac-hE(R)-18A-NH₂respectively. All three peptides increased degradation of LDL by 100 percent. Both Ac-hE-18A-NH₂and the control peptide Ac-18A-NH₂interacted with VLDL to cause a displacement of apo E from VLDL. However, only Ac-hE-18A-NH₂-associated VLDL enhanced the uptake of VLDL six fold and degradation three fold compared to VLDL alone in spite of the absence of apoE. The LDL binding to fibroblasts in the presence of these peptides was not saturable, however, over the LDL concentration range studied.

Furthermore, a similar enhancement of LDL internalization independent of the presence of the LDL receptor related protein (LRP) or LDL receptor or both was seen. Pretreatment of cells with heparinase and heparitinase however abolished greater than 80% of enhanced peptide-mediated LDL uptake and degradation by cells. The data indicated that the dual-domain peptides enhanced LDL uptake and degradation by binding to the LDL through the amphipathic lipid binding domain (18A). However, the minimal 141-150 Arg-rich domain did not decrease LDL levels but did so only in combination with 18A lipid associating domain, did not confer LDL-receptor binding but directed the LDL-peptide complex to the HSPG pathway for uptake and degradation by fibroblasts.

The receptor binding domain peptide for the synthetic Apo E mimetics can also be the LDL receptor (LDLR) binding domain of apolipoprotein B (ApoB). The LDL receptor (LDLR) binding domain of ApoB can have the sequence RLTRKRGLK. ApoB-100 is a 550,000 Da glycoprotein with nine amino acids (3359-3367) serving as the binding domain for the LDL receptor (Segrest et al., J. Lipid. Res. 42, pp. 1346-1367 (2001)). Upon binding to LDLR in clathrin coated pits, LDL is internalized via endocytosis and moves into the endosome where a drop in pH causes the receptor to dissociate from the LDL. The receptor is recycled back to the surface of the cell while the LDL is moved into the lysosome where the particle is degraded (Goldstein et al., Ann. Rev. Cell Biol. 1, pp. 1-39 (1985)). The LDL receptor (LDLR) binding domain of ApoB when used with the disclosed peptides can also be altered and/or modified as described throughout this application for Apo E. For example, LDL receptor (LDLR) binding domain of ApoB can be used with the disclosed lipid-associating peptides, wherein the LDL receptor (LDLR) binding domain of ApoB is covalently linked to said lipid-associating peptide. In addition, the LDL receptor (LDLR) binding domain of ApoB can be scrambled, reverse-oriented, can be part of a domain switched peptide as described below.

ii. Lipid-Associating Peptides

Lipid-associating peptides can be used alone or in combination with the Apo E-mimicking peptides. The lipid associating peptide for these synthetic Apo E mimetics can be, but are not limited to, class A amphipathic helical peptides, class A amphipathic helical peptide mimetics of apoA-I having aromatic or aliphatic residues in the non-polar face, small peptides including pentapeptides, tetrapeptides, tripeptides, dipeptides and pairs of amino acids, Apo-J (G* peptides), and peptide mimetics, e.g., as described below.

a. Class A Amphipathic Helical Peptides

In one aspect, the lipid-associating peptides for use in the disclosed methods include class A amphipathic helical peptides, e.g. as described in U.S. Pat. No. 6,664,230, and PCT Publications WO 02/15923 and WO 2004/034977. It was discovered that peptides comprising a class A amphipathic helix (“class A peptides”), are capable of mitigating one or more symptoms of atherosclerosis as well as treating other disorders.

Class A peptides are characterized by formation of an α-helix that produces a segregation of polar and non-polar residues thereby forming a polar and a nonpolar face with the positively charged residues residing at the polar-nonpolar interface and the negatively charged residues residing at the center of the polar face (see, e.g., Anantharamaiah (1986) Meth. Enzymol, 128: 626-668). It is noted that the fourth exon of apo A-I, when folded into 3.667 residues/turn produces a class A amphipathic helical structure.

One class A peptide, designated 18A (see, e.g., Anantharamaiah (1986) Meth. Enzymol, 128: 626-668) was modified as described herein to produce peptides orally administrable and highly effective at inhibiting or preventing one or more symptoms of atherosclerosis and/or other indications described herein. Without being bound by a particular theory, it is believed that the disclosed peptides can act in vivo by picking up seeding molecule(s) that mitigate oxidation of LDL.

Increasing the number of Phe residues on the hydrophobic face of 18A can increase lipid affinity as determined by the computation described by Palgunachari et al. (1996) Arteriosclerosis, Thrombosis, & Vascular Biol. 16: 328-338. Theoretically, a systematic substitution of residues in the nonpolar face of 18A with Phe could yield six peptides. Peptides with an additional 2, 3 and 4 Phe would have theoretical lipid affinity (2) values of 13, 14 and 15 units, respectively. However, the λ values jumped four units if the additional Phe were increased from 4 to 5 (to 19λ units). Increasing to 6 or 7 Phe would produce a less dramatic increase (to 20 and 21λ units, respectively).

A number of these class A peptides were made including, the peptide designated 4F, D4F, 5F, and D5F, and the like. Various class A peptides inhibited lesion development in atherosclerosis-susceptible mice and rabbits. In addition, the peptides show varying, but significant degrees of efficacy in mitigating one or more symptoms of the various pathologies described herein. A number of such peptides are illustrated in Table 2.

*Linkers are underlined; NMA is N-Methyl Anthranilyl

In certain aspects, the peptides include variations of 4F (D-W—F—K-A-F—Y-D-K—V-A-E-K—F—K-E-A-F (SEQ ID NO:16) in Table 2), also known as L-4F, where all residues are L form amino acids) or D-4F where one or more residues are D form amino acids). In any of the peptides described herein, the C-terminus, and/or N-terminus, and/or internal residues can be blocked with one or more blocking groups as described herein.

While various peptides of Table 2, are illustrated with an acetyl group or an N-methylanthranilyl group protecting the amino terminus and an amide group protecting the carboxyl terminus, any of these protecting groups may be eliminated and/or substituted with another protecting group as described herein. The peptides can comprise one or more D-form amino acids as described herein. In certain aspects, every amino acid (e.g., every enantiomeric amino acid) of the peptides of Table 2 is a D-form amino acid.

It is also noted that Table 2 is not fully inclusive. Using the teachings provided herein, other suitable class A amphipathic helical peptides can routinely be produced (e.g., by conservative or semi-conservative substitutions (e.g., D replaced by E), extensions, deletions, and the like). Thus, for example, one embodiment utilizes truncations of any one or more of peptides shown herein (e.g., peptides identified as 2F, 3F, 3F¹⁴, 4F, 5F, 6F, or 7F—in Table 2). Thus, for example, A-F—Y-D-K—V-A-E-K-L-K-E-A-F (amino acids 5-18 of SEQ ID NO:5) illustrates a peptide comprising 14 amino acids from the C-terminus of 18A comprising one or more D amino acids, while others illustrate other truncations.

Longer peptides are also suitable. Such longer peptides may entirely form a class A amphipathic helix, or the class A amphipathic helix (helices) can form one or more domains of the peptide. In addition, this invention contemplates multimeric versions of the peptides (e.g., concatamers). Thus, for example, the peptides illustrated herein can be coupled together (directly or through a linker (e.g., a carbon linker, or one or more amino acids) with one or more intervening amino acids). Illustrative polymeric peptides include 18A-Pro-18A and the peptides in the following table (Table 2B), in certain embodiments comprising one or more D amino acids, more preferably with every amino acid a D amino acid as described herein and/or having one or both termini protected.

b. Class A Amphipathic Helical Peptide Mimetics of apoA-I Having Aromatic or Aliphatic Residues in the Non-Polar Face.

Also disclosed are modified class A amphipathic helix peptides. Certain preferred peptides incorporate one or more aromatic residues at the center of the nonpolar face, e.g., 3F^Cπ, (as present in 4F), or with one or more aliphatic residues at the center of the nonpolar face, e.g., 3F^Iπ, see, e.g., Table 3. Without being bound to a particular theory, the central aromatic residues on the nonpolar face of the peptide 3F^Cπ, due to the presence of π electrons at the center of the nonpolar face can allow water molecules to penetrate near the hydrophobic lipid alkyl chains of the peptide-lipid complex, which in turn would enable the entry of reactive oxygen species (such as lipid hydroperoxides) shielding them from the cell surface. The peptides with aliphatic residues at the center of the nonpolar face, e.g., 3F^Iπ, can act similarly but not quite as effectively as 3F^Cπ.

In one aspect, the peptides can convert pro-inflammatory HDL to anti-inflammatory HDL or make anti-inflammatory HDL more anti-inflammatory, and/or decrease LDL-induced monocyte chemotactic activity generated by artery wall cells equal to or greater than D4F or other peptides shown in Table 2.

c. Other Class A and Some Class Y Amphipathic Helical Peptides.

Class A amphipathic helical peptides that have an amino acid composition identical to one or more of the class A amphipathic helical peptides described above. Thus, for example, in certain embodiments this invention contemplates peptides having an amino acid composition identical to 4F. Thus, in certain embodiments, this invention includes active agents that comprise a peptide that consists of 18 amino acids, where the 18 amino acids consist of 3 alanines (A), 2 aspartates (D), 2 glutamates (E), 4 phenylalanines (F), 4 lysines (K), 1 valine (V), 1 tryptophan (W), and 1 tyrosine (Y); and where the peptide forms a class A amphipathic helix; and protects a phospholipid against oxidation by an oxidizing agent. In various embodiments, the peptides comprise least one “D” amino acid residue; and in certain embodiments, the peptides comprise all “D: form amino acid residues. A variety of such peptides are illustrated in Table 4. Reverse (retro-), inverse, retro-inverso-, and circularly permuted forms of these peptides are also contemplated. Table 4 provides the sequences and identifier names for representative 18 amino acid length class A amphipathic helical peptides with the amino acid composition comprising 3 alanines (A), 2 aspartates (D), 2 glutamates (E), 4 phenylalanines (F), 4 lysines (K), 1 valine (V), 1 tryptophan (W), and 1 tyrosine (Y).

It is possible to readily identify biologically active and useful peptides. Thus, for example, the following peptides have been accurately identified as active: 3F1; 3F2; 4F the reverse (retro) forms thereof and the retro-inverso forms thereof. Lipid-associating peptides can comprise a peptide that is 18 amino acids in length and forms a class A amphipathic helix where the peptide has the amino acid composition 2 aspartates, 2 glutamates, 4 lysines, 1 tryptophan, 1 tyrosine, no more than one leucine, no more than 1 valine, no less than 1 and no more than 3 alanines, and with 3 to 6 amino acids from the group: phenylalanine, alpha-naphthalanine, beta-naphthalanine, histidine, and contains either 9 or 10 amino acids on the polar face in a helical wheel representation of the class A amphipathic helix including 4 amino acids with positive charge at neutral pH with two of the positively charged residues residing at the interface between the polar and non-polar faces and with two of the four positively charged residues on the polar face that are contiguous and on the non-polar face two of the amino acid residues from the group: phenylalanine, alpha-naphthalanine, beta-naphthalanine, histidine are also contiguous and if there are 4 or more amino acids from this group on the non-polar face there are also at least 2 residues from this group that are not contiguous. In some instances, all of the acidic amino acids are glutamic acid rather than having two aspartic acids and two glutamic acids. In some aspects, the lipid associating peptide can be 18A, wherein each of the acidic amino acids of 18A are Glu residues.

Certain class Y as well as class A amphipathic helical peptides are disclosed. Class Y amphipathic helical peptides are known to those of skill in the art (see, e.g., Segrest et al. (1992) J. Lipid Res. 33: 141-166; Oram and Heinecke (2005) Physiol Rev. 85: 1343-1372, and the like). These peptides include, but are not limited to, an 18 amino acid peptide that forms a class A amphipathic helix or a class Y amphipathic helix described by formula I:

(SEQ ID NO: 367)

D X X K Y X X D K X Y D K X K D Y X (I)

where the D's are independently Asp or Glu; the Ks are independently Lys or Arg; the Xs are independently Leu, nor Leu, Val, Ile, Trp, Phe, Tyr, β-Nal, or α-Nal and all X residues are on the non-polar face (e.g., when viewed in a helical wheel diagram) except for one that can be on the polar face between two K residues; the Y's are independently Ala, His, Ser, Gln, Asn, or Thr non-polar face (e.g., when viewed in a helical wheel diagram) and the Y's are independently one Ala on the polar face, one His, one Ser, one Gln one Asn, or one Thr on the polar face (e.g., when viewed in a helical wheel diagram), where no more than two K are be contiguous (e.g., when viewed in a helical wheel diagram); and where no more than 3 D's are contiguous (e.g., when viewed in a helical wheel diagram) and the fourth D is be separated from the other D's by a Y. Representative peptides of this kind which include peptides with histidine, and/or alpha- and/or beta-napthalanine are shown in Table 5. Reverse (retro-), inverse, retro-inverso-, and circularly permuted forms of these peptides are also contemplated.

iii. Scrambled Peptides

Also disclosed are synthetic Apo E-mimicking peptides, consisting of: a receptor binding domain of apolipoprotein E and a lipid-associating peptide, wherein said receptor binding domain is covalently linked to said lipid-associating peptide, wherein the receptor binding domain of apolipoprotein E is scrambled. For example, disclosed is a synthetic apolipoprotein E-mimicking peptide, consisting of: a receptor binding domain of apolipoprotein E comprising the amino acid sequence of D-W-L-K-A-F—V—Y-D-K—V—F—K-L-K-E-F—F (SEQ ID NO:69); and a lipid-associating peptide, wherein said receptor binding domain is covalently linked to said lipid-associating peptide. Also disclosed are synthetic Apo E-mimicking peptides, consisting of: a receptor binding domain of apolipoprotein B and a lipid-associating peptide, wherein said receptor binding domain is covalently linked to said lipid-associating peptide, wherein the receptor binding domain of apolipoprotein B is scrambled.

iv. Linkages

Any suitable linker can be used in accordance with the present invention. The peptide linkages can be selected from the group consisting of: —CH₂NH—, —CH₂S—, —CH₂—CH₂—, —CH═CH—(cis and trans), —COCH₂—, —CH(OH)CH₂—, —CH₂SO—, etc. by methods known in the art and further described in the following references: Spatola (1983) p. 267 in Chemistry and Biochemistry of Amino Acids, Peptides, and Proteins, B. Weinstein, eds., Marcel Dekker, New York; Spatola (1983) Vega Data 1(3) Peptide Backbone Modifications. (general review); Morley (1980) Trends Pharm Sci pp. 463-468 (general review); Hudson et al. (1979) Int J PeptProt Res 14:177-185 (—CH₂NH—, CH₂CH₂—); Spatola et al. (1986) Life Sci 38:1243-1249 (—CH₂—S); Hann, (1982) J ChemSoc Perkin Trans I 307-314 (—CH—CH—, cis and trans); Almquist et al. (1980) J Med. Chem. 23:1392-1398 (—COCH₂—); Jennings-White et al. (1982) Tetrahedron Lett. 23:2533 (—COCH₂—); Szelke et al., European Appln. EP 45665 (1982) CA: 97:39405 (1982) (—CH(OH)CH2-); Holladay et al. (1983) Tetrahedron Lett 24:4401-4404 (—C(OH)CH₂—); and Hruby (1982) Life Sci., 31:189-199 (—CH₂—S—)).

One particularly preferred non-peptide linkage is —CH₂NH—. Such peptide mimetics may have significant advantages over polypeptide embodiments, including, for example: more economical production, greater chemical stability, enhanced pharmacological properties (half-life, absorption, potency, efficacy, etc.), reduced antigenicity, and others.

In one aspect, the linker is a cleavable linker. To give but a few examples, cleavable linkers include protease cleavable peptide linkers, nuclease sensitive nucleic acid linkers, lipase sensitive lipid linkers, glycosidase sensitive carbohydrate linkers, pH sensitive linkers, hypoxia sensitive linkers, photo-cleavable linkers, heat-labile linkers, enzyme cleavable linkers (e.g., esterase cleavable linker), ultrasound-sensitive linkers, x-ray cleavable linkers, etc.

5. Variants

The receptor binding domain or the lipid-associating peptide can be modified or altered as described above. For example, the receptor binding domain or the lipid-associating peptide can be mutated, scrambled, and/or reverse-oriented. Any other modifications or alterations disclosed herein for the dual-domain polypeptides can also be used for the single-domain peptides.

Numerous other variants or derivatives of the peptides disclosed herein are also contemplated. For example, scrambled peptides can also be reverse-oriented, or can be in a switched orientation. Additionally, reverse-oriented peptides can be in a switched orientation. All other combinations of the disclosed peptides are also contemplated. Non-limiting examples of the peptides have been described herein (see Tables 1-5, for example). As used herein, the term “analog” is used interchangeably with “variant” and “derivative.” Variants and derivatives are well understood to those of skill in the art and can involve amino acid sequence modifications. Such, amino acid sequence modifications typically fall into one or more of three classes: substantial; insertional; or deletional variants. Insertions include amino and/or carboxyl terminal fusions as well as intrasequence insertions of single or multiple amino acid residues. Insertions ordinarily are smaller insertions than those of amino or carboxyl terminal fusions, for example, on the order of one to four residues. These variants ordinarily are prepared by site-specific mutagenesis of nucleotides in the DNA encoding the protein, thereby producing DNA encoding the variant, and thereafter expressing the DNA in recombinant cell culture. Techniques for making substitution mutations at predetermined sites in DNA having a known sequence are well known, for example M13 primer mutagenesis and PCR mutagenesis. Amino acid substitutions are typically of single residues, but can occur at a number of different locations at once. Substitutions, deletions, insertions or any combination thereof may be combined to arrive at a final derivative or analog. Substitutional variants are those in which at least one residue has been removed and a different residue inserted in its place. Such substitutions generally are made in accordance with Tables 11 and 12 and are referred to as conservative substitutions.

Substantial changes in function or immunological identity are made by selecting substitutions that are less conservative than those in Table 11, i.e., selecting residues that differ more significantly in their effect on maintaining (a) the structure of the polypeptide backbone in the area of the substitution, for example as a sheet or helical conformation, (b) the charge or hydrophobicity of the molecule at the target site, or (c) the bulk of the side chain. The substitutions which in general are expected to produce the greatest changes in the protein properties are those in which: (a) the hydrophilic residue, e.g. seryl or threonyl, is substituted for (or by) a hydrophobic residue, e.g., leucyl, isoleucyl, phenylalanyl, valyl or alanyl; Tryptophan, Tyrosinyl (b) a cysteine or proline is substituted for (or by) any other residue; (c) a residue having an electropositive side chain, e.g., lysyl, arginyl, or hystidyl, is substituted for (or by) an electronegative residue, e.g. glutamyl or aspartyl; or (d) a residue having a bulky side chain, e.g., phenylalanine, is substituted for (or by) one not having a side chain, e.g., glycine, in this case, or (e) by increasing the number of sites for sulfation and/or glycosylation.

It is understood that one way to define the variants and derivatives of the disclosed proteins herein is to define them in terms of homology/identity to specific known sequences. Specifically disclosed are variants of synthetic Apo E mimetics and other proteins or peptides herein disclosed which have at least, 70% or at least 75% or at least 80% or at least 85% or at least 90% or at least 95% homology to the synthetic Apo E mimetics specifically recited herein. Those of skill in the art readily understand how to determine the homology of two proteins.

The polypeptides can be modified by either natural processes, such as posttranslational processing, or by chemical modification techniques which are well known in the art. Modifications can occur anywhere in the polypeptide, including the peptide backbone, the amino acid side-chains and the amino or carboxyl termini. The same type of modification can be present in the same or varying degrees at several sites in a given polypeptide. Also, a given polypeptide can have many types of modifications. Modifications include, without limitation, acetylation, acylation, ADP-ribosylation, amidation, covalent cross-linking or cyclization, covalent attachment of flavin, covalent attachment of a heme moiety, covalent attachment of a nucleotide or nucleotide derivative, covalent attachment of a lipid or lipid derivative, covalent attachment of a phosphytidylinositol, disulfide bond formation, demethylation, formation of cysteine or pyroglutamate, formylation, gamma-carboxylation, glycosylation, GPI anchor formation, hydroxylation, iodination, methylation, myristolyation, oxidation, pegylation, proteolytic processing, phosphorylation, prenylation, racemization, selenoylation, sulfation, and transfer-RNA mediated addition of amino acids to protein such as arginylation. (See Proteins—Structure and Molecular Properties 2nd Ed., T. E. Creighton, W.H. Freeman and Company, New York (1993); Posttranslational Covalent Modification of Proteins, B. C. Johnson, Ed., Academic Press, New York, pp. 1-12 (1983)).

Variants can also include peptidomimetics. As used herein, “peptidomimetic” means a mimetic of a function of a protein which includes some alteration of the normal peptide chemistry. Peptidomimetics typically are short sequences of amino acids that in biological properties mimic one or more function(s) of a particular protein. Peptide analogs enhance some property of the original peptide, such as increases stability, increased efficacy, enhanced delivery, increased half-life, etc. Methods of making peptidomimetics based upon a known polypeptide sequence is described, for example, in U.S. Pat. Nos. 5,631,280; 5,612,895; and 5,579,250. Use of peptidomimetics can involve the incorporation of a non-amino acid residue with non-amide linkages at a given position. One embodiment of the present invention is a peptidomimetic wherein the compound has a bond, a peptide backbone or an amino acid component replaced with a suitable mimic Some non-limiting examples of unnatural amino acids which may be suitable amino acid mimics include β-alanine, L-α-amino butyric acid, L-γ-amino butyric acid, L-α-amino isobutyric acid, L-ε-amino caproic acid, 7-amino heptanoic acid, L-aspartic acid, L-glutamic acid, N-ε-Boc-N-α-CBZ-L-lysine, N-ε-Boc-N-α-Fmoc-L-lysine, L-methionine sulfone, L-norleucine, L-norvaline, N-α-Boc-N-δCBZ-L-omithine, N-δ-Boc-N-α-CBZ-L-ornithine, Boc-p-nitro-L-phenylalanine, Boc-hydroxyproline, and Boc-L-thioproline.

6. Nucleic Acids

As this specification discusses various peptide sequences it is understood that the nucleic acids that can encode those polypeptide sequences are also disclosed. This would include all degenerate sequences related to a specific polypeptide sequence, i.e. all nucleic acids having a sequence that encodes one particular polypeptide sequence as well as all nucleic acids, including degenerate nucleic acids, encoding the disclosed variants and derivatives of the protein sequences. Thus, while each particular nucleic acid sequence may not be written out herein, it is understood that each and every sequence is in fact disclosed and described herein through the disclosed polypeptide sequences.

7. Blocking/Protecting Groups and D Residues

The disclosed compositions can comprise an acetyl group followed by a protecting group. The protecting group can be, but is not limited to, a fatty acid. The fatty acids can be saturated, unsaturated or essential fatty acids. Fatty acids can include but are not limited to DHA, EPA, linoleic acid, or any other saturated amino acid such as myristic acid.

While the various compositions described herein may be shown with no protecting groups, in certain embodiments (e.g., particularly for oral administration), they can bear one, two, three, four, or more protecting groups. The protecting groups can be coupled to the C- and/or N-terminus of the peptide(s) and/or to one or more internal residues comprising the peptide(s) (e.g., one or more R-groups on the constituent amino acids can be blocked). Thus, for example, in certain embodiments, any of the peptides described herein can bear, e.g., an acetyl group protecting the amino terminus and/or an amide group protecting the carboxyl terminus. One example of such a “dual protected peptide” is Ac-LRKLRKRLLRDWLKAFYDKVAEKLKEAF-NH₂(SEQ ID NO:1) with blocking groups), either or both of these protecting groups can be eliminated and/or substituted with another protecting group as described herein. Without being bound by a particular theory, it was a discovery of this invention that blockage, particularly of the amino and/or carboxyl termini of the subject peptides of this invention can improve oral delivery and can also increase serum half-life.

A wide number of protecting groups are suitable for this purpose. Such groups include, but are not limited to acetyl, amide, and alkyl groups with acetyl and alkyl groups being particularly preferred for N-terminal protection and amide groups being preferred for carboxyl terminal protection. For example, the protecting groups can include, but are not limited to alkyl chains as in fatty acids, propeonyl, formyl, and others. Carboxyl protecting groups include amides, esters, and ether-forming protecting groups can also be used. For example, an acetyl group can be used to protect the amino terminus and an amide group can be used to protect the carboxyl terminus. These blocking groups enhance the helix-forming tendencies of the peptides. Additional blocking groups include alkyl groups of various lengths, e.g., groups having the formula: CH₃(CH₂)_nCO where n ranges from about 1 to about 20, preferably from about 1 to about 16 or 18, more preferably from about 3 to about 13, and most preferably from about 3 to about 10.

Additionally, the protecting groups include, but are not limited to alkyl chains as in fatty acids, propeonyl, formyl, and others. For example, carboxyl protecting groups can include amides, esters, and ether-forming protecting groups. These blocking groups can enhance the helix-forming tendencies of the peptides. Blocking groups can include alkyl groups of various lengths, e.g., groups having the formula: CH₃(CH₂)_nCO where n ranges from about 3 to about 20, preferably from about 3 to about 16, more preferably from about 3 to about 13, and most preferably from about 3 to about 10.

Other protecting groups include, but are not limited to Fmoc, t-butoxycarbonyl (t-BOC), 9-fluoreneacetyl group, 1-fluorenecarboxylic group, 9-florenecarboxylic group, 9-fluorenone-1-carboxylic group, benzyloxycarbonyl, Xanthyl (Xan), Trityl (Trt), 4-methyltrityl (Mtt), 4-methoxytrityl (Mmt), 4-methoxy-2,3,6-trimethyl-benzenesulphonyl (Mtr), Mesitylene-2-sulphonyl (Mts), 4,4-dimethoxybenzhydryl (Mbh), Tosyl (Tos), 2,2,5,7,8-pentamethyl chroman-6-sulphonyl (Pmc), 4-methylbenzyl (MeBzl), 4-methoxybenzyl (MeOBzl), Benzyloxy (BzlO), Benzyl (Bzl), Benzoyl (Bz), 3-nitro-2-pyridinesulphenyl (Npys), 1-(4,4-dimentyl-2,6-diaxocyclohexylidene)ethyl (Dde), 2,6-dichlorobenzyl (2,6-DiCl-Bzl), 2-chlorobenzyloxycarbonyl (2-Cl—Z), 2-bromobenzyloxy-carbonyl (2-Br—Z), Benzyloxymethyl (Bom), cyclohexyloxy (cHxO), t-butoxymethyl (Bum), t-butoxy (tBuO), t-Butyl (tBu), Acetyl (Ac), and Trifluoroacetyl (TFA).

Protecting/blocking groups are well known to those of skill as are methods of coupling such groups to the appropriate residue(s) comprising the peptides of this invention (see, e.g., Greene et al., (1991) Protective Groups in Organic Synthesis, 2nd ed., John Wiley & Sons, Inc. Somerset, N.J.). For example, acetylation can be accomplished during the synthesis when the peptide is on the resin using acetic anhydride. Amide protection can be achieved by the selection of a proper resin for the synthesis.

The compositions disclosed herein can also comprise one or more D-form (dextro rather than levo) amino acids as described herein. For example, at least two enantiomeric amino acids, at least 4 enantiomeric amino acids or at least 8 or 10 enantiomeric amino acids can be in the “D” form amino acids. Additionally, every other, or even every amino acid (e.g., every enantiomeric amino acid) of the peptides described herein is a D-form amino acid.

Additionally, at least 50% of the enantiomeric amino acids can be “D” form, at least 80% of the enantiomeric amino acids are “D” form, at least 90%, or even all of the enantiomeric amino acids can be in the “D” form amino acids.

FMOC-Aha can be added to the growing chain as the last amino acid using the normal amino acid chain extension procedure (use of HOBt+DCC or HBTU as condensing agents). After the removal of the FMOC group using 20% piperidine in DMF, the NH2 can be acetylated using either excess of acetic anhydride under basic conditions or by condensing acetic acid using amino acid condensing agents used for peptide chain elongation.

H. Monoclonal Antibodies

Disclosed are monoclonal antibodies that specifically bind to any one of the synthetic ApoE-mimicking peptides described herein.

I. Dosing Regimens

Disclosed are dosing regimens comprising at least one treatment cycle of an effective amount of any of the disclosed Apo E-mimicking peptides followed by a rest phase. The rest phase of the dosing regimen is a period of time where the Apo E-mimicking peptide is not administered. The ApoE-mimicking peptide can be, but is not limited to, Ac-Aha-hE18A-NH₂or Ac-Aha-[R]hE18A-NH₂.

Disclosed are dosing regimens comprising at least one treatment cycle followed by a rest phase, wherein the treatment cycle comprises administering an effective amount of an Apo E-mimicking peptide to allow for a sustained therapeutic effect after withdrawal of the Apo E-mimicking peptide, wherein the Apo E-mimicking peptide is not administered during the rest phase. Not only does an effective amount of Apo E-mimicking peptide result in sustained therapeutic effects, but it is also an amount sufficient to cause an acute beneficial effect. Thus, the effects of the Apo E-mimicking peptide can be measured and seen during the treatment cycle, at the end of the treatment cycle and during the rest phase. The sustained therapeutic effects are the therapeutic effects seen even after an acute cholesterol lowering effect is gone.

Disclosed herein are dosing regimens comprising at least one treatment cycle followed by a rest phase, wherein the treatment cycle comprises administering an effective amount of an Apo E-mimicking peptide to allow for a sustained therapeutic effect after withdrawal of the Apo E mimetic, wherein the Apo E-mimicking peptide is not administered during the rest phase, wherein the treatment cycle comprises administration of an effective amount of the Apo E-mimicking peptide once a week for three months or wherein the treatment cycle comprises administration of an effective amount of the Apo E-mimicking peptide once every two weeks for up to 12 weeks.

In one aspect, dosing regimens can comprise at least one treatment cycle followed by a rest phase, wherein the treatment cycle comprises administering an effective amount of a synthetic ApoE-mimicking peptide comprising a receptor binding domain of ApoE and a lipid-associating peptide to allow for a sustained therapeutic effect after withdrawal of the Apo E-mimicking peptide, wherein the Apo E-mimicking peptide is not administered during the rest phase, wherein the synthetic ApoE-mimicking peptide comprises an Ac-Aha.

Dosing regimens can further include a second treatment cycle after the rest phase. A second rest phase can occur after the second treatment cycle. In some instances a third, fourth, fifth, sixth, seventh, eighth, ninth or tenth treatment cycle can be administered wherein each treatment cycle is followed by a rest phase. In one aspect, the dosing regimen includes infinite treatment cycles, each followed by a rest phase. For example, a subject may be prescribed a dosing regimen that involves consecutive treatment cycles followed by rest phases for the duration of their life.

In one aspect, a second dosing regimen can be prescribed based on the re-occurrence of atherosclerotic lesions or other atherosclerosis factors. The second dosing regimen can be administered 1, 2, 3, 4, 5 years or more than 5 years after the initial dosing regimen was administered. The second dosing regimen can be the same as the initial dosing regimen or can be different. For example, the initial dosing regimen can be a three month treatment cycle followed by a one year rest phase. After the one year rest phase the subject can be tested and if atherosclerotic lesions are building up again then a second dosing regimen consisting of another three month treatment cycle followed by a rest phase or a six month treatment cycle followed by a rest phase can be prescribed. The dose of Apo E mimetic can vary between the initial dosing regimen and any additionally prescribed dosing regimens.

In some instances, the second dosing can be administered based on vasoresponsiveness, presence of isolated systolic hypertension, or exercise-induced angina determined in the subject after the first treatment. In some instances, the second dose can be administered based on the amount of plasma cholesterol. The frequency of administration can be altered depending on the need for reducing plasma cholesterol to minimize or eliminate the risk for any of the disorders disclosed herein.

1. Treatment Cycle

Treatment cycles can include the administration of different dosages of ApoE-mimicking peptide as well as administration at different time points. The ApoE-mimicking peptide can be administered for varying amounts of time for up to 6 months. In some instances, the administration can occur for up to one, two, three, four, five or six months. For example, the ApoE-mimicking peptide can be administered once a week for 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, or 24 weeks.

The length of time for each treatment cycle can vary depending on the amount of ApoE-mimicking peptide administered per dosage. A treatment cycle can include the administration of ApoE-mimicking peptide once, twice or three times a week. In some aspects, the ApoE-mimicking peptide can be administered daily. In some aspects, the ApoE-mimicking peptide can be administered once every two weeks or even once a month. In some instances, the Apo E mimetic can be administered every two weeks for 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, or 24 weeks. For example, the treatment cycle can include administering an ApoE-mimicking peptide once a week for four weeks or once every two weeks for up to six months. Thus, each treatment cycle includes an established length of time for administration as well as an established dosing schedule during that time frame.

In one aspect, more than one ApoE-mimicking peptide can be administered during the treatment cycles. The more than one ApoE-mimicking peptide can be formulated together or in separate compositions. In some instances, one or more Apo E mimetic is administered in combination with one or more other therapeutic agents, such as cholesterol lowering drugs.

2. Rest Phase

The disclosed dosing regimens can include at least one treatment cycle followed by a rest phase. The rest phase is a period of time wherein ApoE-mimicking peptide is not administered and the length of the period of time can vary. The length of the rest phase is dependent on how long the sustained therapeutic effects of the Apo E mimetic administered during the treatment cycle last. In some instances the rest phase can be at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months. In some instances the rest phase can be at least 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 years. For example, the rest phase can be at least four weeks (one month).

One way to determine how long the rest phase should last is to test the subject to determine the progression of the atherosclerosis burden in the subject's arteries. If the atherosclerosis burden has progressed to a level that increases the risk of cardiovascular disease, then the subject can be prescribed a second dosing regimen. If the atherosclerosis burden is stable then the rest phase can be prolonged. The length of the reset phase can also be based on VLDL reduction, LDL reduction, glucose reduction, inflammation reduction, vasoresponsiveness, presence of isolated systolic hypertension, or exercise-induced angina, or amount of plasma cholesterol. Subjects can be tested on a regular basis. For example, a subject can be tested every 3, 6, 9, 12, 18, 24, 30 or 36 months.

In one aspect, the rest phase can be decreased or extended depending on the dose of ApoE-mimicking peptide administered and the reduction in atherosclerosis achieved during the treatment cycle. For example, the rest phase can be extended if the dose of ApoE-mimicking peptide during the treatment cycle is increased and the atherosclerosis burden is substantially reduced. The length of the rest phase can also vary based on the length of the treatment cycle. For instance, if a subject receives a certain dose of ApoE-mimicking peptide once a week for three months then the rest phase may be shorter than a subject that receives the same dose of Apo E mimetic once a week for six months.

Although an Apo E mimetic is not administered during the rest phase, an atherosclerosis therapeutic other than an Apo E mimetic can be administered during the rest phase. The atherosclerosis therapeutic other than an Apo E mimetic can be a conventional lipid lowering therapy, such as a statin, a bile acid sequestrant or a fibrate, or a novel anti-atherosclerosis therapeutic like a CETP inhibitor, a VLDL synthesis inhibitor, a PCSK9 inhibitor, and/or an arterial inflammation inhibitor. In other words, the atherosclerosis therapeutic other than an Apo E mimetic can be a conventional LDL lowering therapeutic or a HDL elevating therapeutic.

In some instances, the beneficial effects of the Apo E mimetic can still be present in a subject even after the treatment cycle is complete. In one instance, the half-life of the Apo E mimetic is less than 1, 2, 3, 4, 5, 10, 15, 20, 25, or 30 days. In some instances the Apo E mimetic is no longer detectable in a subject after the treatment cycle is complete. Thus, the long-term therapeutic effects are not from residual Apo E mimetic.

3. Dose

The dose or dosage of ApoE-mimicking peptide can vary depending on many factors, such as but not limited to, age, condition, sex and extent of the disease in the patient, route of administration, length of treatment cycle, or whether other drugs are included in the regimen, and can be determined by one of skill in the art.

Effective dosages can be determined empirically, and making such determinations is within the skill in the art. The dosage ranges for the administration of the compositions are those large enough to produce the desired effect in which the disease is treated. For example, the dosage can be an amount effective to provide therapeutic effects and provide or allow for sustained therapeutic effects even after the treatment (i.e. ApoE-mimicking peptide) is withdrawn. The therapeutic effects can be, but are not limited to, a reduction in atherosclerotic lesions, decrease in arterial stiffness, decrease in isolated systolic hypertension, increase in vasoresponsiveness or improvement in cardiac function. The therapeutic effects can be measured by markers of arterial inflammation such as, but not limited to, C-reactive protein. The therapeutic effects can be measured by atherosclerosis imaging techniques, including MRI, intravascular ultrasound, ultrafast imaging CT scans, B-mode ultrasonography, virtual histology intravascular ultrasound, optical coherence tomography, or other known methods.

The dosage should not be so large as to cause adverse side effects, such as unwanted cross-reactions, anaphylactic reactions, and the like. The dosage can be adjusted by the individual physician in the event of any counter-indications. Dosage can vary, and can be administered in one or more dose administrations daily, for one or several days. Guidance can be found in the literature for appropriate dosages for given classes of pharmaceutical products.

Suitable dosages include, but are not limited to amounts between 0.01 mg/kg and 20 mg/kg. For example, disclosed herein are methods involving administering one or more of the disclosed ApoE-mimicking peptide to a subject, wherein the ApoE-mimicking peptide is administered in an amount of about 0.01 mg/kg to about 20 mg/kg. For example, the concentration of the ApoE-mimicking peptide can be 0.01, 0.1, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, or 20 mg/kg.

The ApoE-mimicking peptide dose can be administered as a bolus injection or as an infusion over one or more hours.

The ACS therapeutic other than an Apo E-mimicking peptide can be a conventional LDL lowering therapy or HDL elevating therapy. A conventional LDL lowering therapy can be, but is not limited to, a statin. An HDL elevating therapy can be, but is not limited to, Apo A1 elevating drug, a CETP inhibitor, a phospholipase A2 inhibitor, an Apo A1 Milano, or an Apo A1 mimetic.

Disclosed herein are methods of treating atherosclerosis comprising administering to a subject an effective amount of an Apo E mimetic for at least one treatment cycle, wherein the treatment cycle comprises administering an effective amount of an Apo E mimetic to allow for a sustained therapeutic effect after withdrawal of the Apo E mimetic, wherein the Apo E mimetic consists of the Ac-Aha-hE18A-NH₂or Ac-Aha-[R]hE18A-NH₂peptide, wherein the treatment cycle is followed by a rest phase, wherein Apo E mimetic is not administered during the rest phase.

The disclosed methods of treating can occur at different times depending on the subject. In particular, treatment can occur in a subject considered to be of high, or high residual risk of a cardio- or cerebrovascular event. In one instance, the treatment can be initiated after a subject is stabilized following an acute coronary event. In one instance, the treatment can be initiated immediately after the acute coronary event, or 3, 6, 9, or 12 months after the acute coronary event. The treatment can be initiated following acute interventional cardiology procedures such as coronary artery bypass surgery (CABG), percutaneous coronary intervention (angioplasty, PCI), or implant of a stent into a coronary artery. Subjects considered as high risk can be those individuals that have homozygous familial hypercholesterolemia (FH), severe refractory FH, diabetes or an individual following acute coronary syndrome (ACS). In high risk subjects, treatment can be extended.

1. Treatment Cycle

The treatment cycle, as previously described with respect to the dosing regimens, can vary in length of time. The treatment cycle can be at least four weeks but can last up to six months. In one instance, the disclosed methods have a treatment cycle that involves the administration of an effective amount of an ApoE-mimicking peptide once a week for one month (four weeks), three months (12 weeks) or six months (24 weeks). A treatment cycle can include the administration of ApoE-mimicking peptide once, twice or three times a week. In some aspects, the ApoE-mimicking peptide can be administered daily. In some aspects, the ApoE-mimicking peptide can be administered once every two weeks or even once a month. In some instances, the ApoE-mimicking peptide can be administered every two weeks for 4, 6, 8, 10, 12, 14, 16, 18, 20, 22, or 24 weeks. Each treatment cycle can include an established length of time for administration as well as an established dosing schedule during that time frame.

The methods can further include a second treatment cycle after the rest phase. In one aspect, the second treatment cycle can be administered after a four week rest phase. In another aspect, the second treatment cycle can be administered at least one year from the beginning of the initial treatment cycle.

2. Rest Phase

The rest phase, as previously described with regards to the dosing regimen, can be at least four weeks but can last for several years. The ApoE-mimicking peptide is not administered during the rest phase.

The length of the rest phase is dependent on how long the sustained therapeutic effects of the ApoE-mimicking peptide administered during the treatment cycle last. In some instances the rest phase can be at least 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, or 12 months. In some instances the rest phase can be at least 1, 2, 3, 4, 5, 6, 7, 8, 9, or 10 years. For example, the rest phase can be at least four weeks (one month).

In one aspect, the rest phase can be decreased or extended depending on the dose of ApoE-mimicking peptide administered during the treatment cycle. For example, the rest phase can be extended if the dose of ApoE-mimicking peptide during the treatment cycle is increased. The length of the rest phase can also vary based on the length of the treatment cycle. For instance, if a subject receives a certain dose of ApoE-mimicking peptide once a week for three months then the rest phase may be shorter than a subject that receives the same dose of ApoE-mimicking peptide once a week for six months.

Although an ApoE-mimicking peptide is not administered during the rest phase, an atherosclerosis therapeutic other than an ApoE-mimicking peptide can be administered during the rest phase. The atherosclerosis therapeutic other than an Apo E mimetic can be a conventional lipid lowering therapy, such as a statin, or bile acid sequestrant, and/or a therapeutic such as a PCSK9 inhibitor, a VLDL synthesis inhibitor and/or a CETP inhibitor.

3. Atherosclerosis

The combination of LDL accumulation in a vessel wall and an inflammatory response to the LDL's is responsible for initiating atherosclerosis. The LDL within the vessel wall becomes oxidized which damages the vessel wall and triggers an immune response. Immune cells, such as macrophages, are not able to process the oxidized-LDL and eventually rupture which leads to more oxidized cholesterol in the artery wall. This cycle continues which causes more and more damage to the vessel walls. The increase in cholesterol leads to plaques which ultimately results in hardening and narrowing of the vessel wall. The disclosed methods are useful for treating atherosclerosis and other lipid disorders.

K. Delivery

In the methods described herein, administration or delivery of the ApoE-mimicking peptides can be via a variety of mechanisms. As defined above, disclosed herein are methods of treating, dosing regimens and methods of using those dosing regimens to treat. The dosing regimens and methods include compositions containing any one or more of the polypeptides or nucleic acids described herein that can also include a carrier such as a pharmaceutically acceptable carrier. For example, disclosed are pharmaceutical compositions, comprising the ApoE-mimicking peptide disclosed herein, and a pharmaceutically acceptable carrier.

The disclosed ApoE-mimicking peptide can be in solution or in suspension (for example, incorporated into microparticles, liposomes, or cells). These compositions can be targeted to a particular cell type via antibodies, receptors, or receptor ligands. One of skill in the art knows how to make and use such targeting agents with the disclosed compositions. A targeting agent can be a vehicle such as an antibody conjugated liposomes; receptor mediated targeting of DNA through cell specific ligands, and highly specific retroviral targeting of cells in vivo. Any such vehicles can be part of the compositions herein. For example, targeting agents that direct the ApoE-mimicking peptide to the blood vessel walls can be included in the compositions.

Any suitable route of administration can be used for the disclosed compositions. Suitable routes of administration can, for example, include topical, enteral, local, systemic, or parenteral. For example, administration can be epicutaneous, inhalational, enema, conjunctival, eye drops, ear drops, alveolar, nasal, intranasal, enteral, oral, intraoral, transoral, intestinal, rectal, intrarectal, transrectal, injection, infusion, intravenous, intraarterial, intramuscular, intracerebral, intraventricular, intracerebroventricular, intracardiac, subcutaneous, intraosseous, intradermal, intrathecal, intraperitoneal, intravesical, intracavernosal, intramedullar, intraocular, intracranial, transdermal, transmucosal, transnasal, inhalational, intracisternal, epidural, peridural, intravitreal, etc. The disclosed compositions can be used in and with any other therapy.

Unlike typical peptide formulations, the peptides of this invention comprising D-form amino acids can be administered, even orally, without protection against proteolysis by stomach acid, etc. Nevertheless, in certain embodiments, peptide delivery can be enhanced by the use of protective excipients. This is typically accomplished either by complexing the polypeptide with a composition to render it resistant to acidic and enzymatic hydrolysis or by packaging the polypeptide in an appropriately resistant carrier such as a liposome. Means of protecting polypeptides for oral delivery are well known in the art (see, e.g., U.S. Pat. No. 5,391,377 describing lipid compositions for oral delivery of therapeutic agents).

Elevated serum half-life can be maintained by the use of sustained-release protein “packaging” systems. Such sustained release systems are well known to those of skill in the art. In one preferred embodiment, the ProLease biodegradable microsphere delivery system for proteins and peptides (Tracy (1998) Biotechnol. Prog., 14: 108; Johnson et al. (1996) Nature Med. 2: 795; Herbert et al. (1998), Pharmaceut. Res. 15, 357) a dry powder composed of biodegradable polymeric microspheres containing the active agent in a polymer matrix that can be compounded as a dry formulation with or without other agents.

The ProLease microsphere fabrication process was specifically designed to achieve a high encapsulation efficiency while maintaining integrity of the active agent. The process consists of (i) preparation of freeze-dried drug particles from bulk by spray freeze-drying the drug solution with stabilizing excipients, (ii) preparation of a drug-polymer suspension followed by sonication or homogenization to reduce the drug particle size, (iii) production of frozen drug-polymer microspheres by atomization into liquid nitrogen, (iv) extraction of the polymer solvent with ethanol, and (v) filtration and vacuum drying to produce the final dry-powder product. The resulting powder contains the solid form of the active agents, which is homogeneously and rigidly dispersed within porous polymer particles. The polymer most commonly used in the process, poly(lactide-co-glycolide) (PLG), is both biocompatible and biodegradable.

Encapsulation can be achieved at low temperatures (e.g., −40° C.). During encapsulation, the protein is maintained in the solid state in the absence of water, thus minimizing water-induced conformational mobility of the protein, preventing protein degradation reactions that include water as a reactant, and avoiding organic-aqueous interfaces where proteins may undergo denaturation. A preferred process uses solvents in which most proteins are insoluble, thus yielding high encapsulation efficiencies (e.g., greater than 95%).

In another embodiment, one or more components of the solution can be provided as a “concentrate”, e.g., in a storage container (e.g., in a premeasured volume) ready for dilution, or in a soluble capsule ready for addition to a volume of water.

The foregoing formulations and administration methods are intended to be illustrative and not limiting. It will be appreciated that, using the teaching provided herein, other suitable formulations and modes of administration can be readily devised.

1. Combination Therapy

In one aspect of the disclosed methods, the Apo E mimetics can be administered alone or in combination with one or more additional therapeutic agents. The additional therapeutic agents are selected based on the disease or symptom to be treated. A description of the various classes of suitable pharmacological agents and drugs may be found in Goodman and Gilman, The Pharmacological Basis of Therapeutics, (11th Ed., McGraw-Hill Publishing Co.) (2005). For example, pharmaceutical compositions containing Apo E mimetics can be administered in combination with one or more known therapeutic agents for treating atherosclerosis. Therapeutic agents for treating atherosclerosis include, but are not limited to, cholesterol-lowering agents, HDL elevating agents, blood pressure-lowering agents, blood thinning agents (i.e. medicines that prevent blood clots), anti-inflammatory agents, and anti-atherogenic agents. Examples of cholesterol-lowering agents include, but are not limited to, a cholesterol absorption inhibitor, a bile acid sequestrant, a fibrate, a PCSK9 inhibitor, a microsomal triglyceride transfer protein inhibitor, an apolipoprotein B synthesis inhibitor, or a CETP inhibitor.

The Apo E mimetics can be administered in conjunction with or followed by any of the disclosed additional therapeutics. The treatments can be administered in conjunction with or followed by LDL apheresis.

The combination therapies can include administering the Apo E mimetic and an additional therapeutic agent during the treatment cycle of a dosing regimen. The combination therapies can also include administering the Apo E mimetic during the treatment cycle and an additional therapeutic agent during the rest phase.

EXAMPLES

It is understood that the disclosed method and compositions are not limited to the particular methodology, protocols, and reagents described as these may vary. It is also to be understood that the terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present invention which will be limited only by the appended claims.

Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific embodiments of the method and compositions described herein. Such equivalents are intended to be encompassed by the following claims.

Example 1: Preparation and Analysis of Synthetic ApoE-Mimicking Peptides Analogs

The synthetic ApoE-mimicking peptides used in the studies described in FIGS. 3-14 were prepared were prepared by standard Fmoc solid-phase peptide synthesis techniques. Various peptides and the rationale for preparation are shown in FIG. 1. Representative analytical HPLC profiles of the synthesized peptides are shown in FIGS. 2A-2G.

Example 2: Effect of AEM Analogs in ApoE Null Mice

Studies showing the effects of various synthetic ApoE-mimicking peptides on plasma cholesterol levels are shown in FIGS. 3-14.

Example 3: Effect of AEM Analogs in High-Sucrose Fed Rats

Male Sprague-Dawley rats were purchased from Charles River and fed a diet containing 65% sucrose for two weeks. The lipoprotein profile (FIG. 15) showed an increase of triglycerides. The rats weighed 370+/−2 Og at the time of administration of peptides. The peptides administered (5 mg/kg tail vein) were as follows: Ac-hE18A-NH₂, Ac—[R]hE18A-NH₂and Ac-Aha-[R]hE18A-NH₂where hE refers to LRKLRKRLLR (SEQ ID NO:4) and [R]hE refers to LRRLRRRLLR (SEQ ID NO:6) and Aha refers to H₂N—(CH₂)₅—COOH. Blood was drawn at the times indicated in graphs and after separating cells, plasma was analyzed for cholesterol, triglycerides and glucose levels. Plasma triglycerid levels at different time points are shown in FIG. 16. Data were also obtained at 48 h post-administration of the peptide for plasma triglyceride (FIG. 17), cholesterol levels (FIG. 18), and plasma glucose levels (FIG. 19).

Example 4: Preparation and Analysis of Fatty Acid Containing Peptides

The following peptides were prepared: (1) octanoyl-LRRLRRRLLR-18A-NH₂(SEQ ID NO:625); (2) myristoyl-LRRLRRRLLR-18A-NH₂(SEQ ID NO:628); (3) oleoyl-LRRLRRRLLR-18A-NH₂(SEQ ID NO:634); (4) palmitoyl-LRRLRRRLLR-18A-NH₂(SEQ ID NO:629); and (5) Fish oil-LRRLRRRLLR-18A-NH₂(SEQ ID NO:647), in which fish oil was principally a mixture of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), with other components in small amounts.

The peptides were synthesized on a Rink amide resin (5 mM of the functional group present on 10 g of the resin was used). Suitable FMOC-amino acid derivatives were added using HBTu method of condensation (three couplings for each amino acid at 5×, 3×, and 2× for three couplings). After the last amino acid leucine (L) was added, the resin weighed approximately 40 g, indicating quantitative yield for the coupling of amino acids. Resin (2 g) was taken for each fatty acid and each fatty acid was added two times with 10× and 5× couplings using HBTu in DMF. The peptide was released from the resin using TFA:water:anisole:ethylenedithiol (95:2:2:1 by volume, 10 ml/G of the reagent) for 3.5 hr at room temperature. After filtration of the resin, the peptide was precipitated by adding ether, washed by centrifugation with ether three times. Peptide was first dialyzed and then purified by HPLC. Since fish oil derivative is known to contain mixture that was very difficult to purify, this was not purified but the ability of this peptide to reduce plasma cholesterol in apoE null mice was compared with other dialyzed peptides. Purification of peptides was achieved using C18 silica gel column, and FIGS. 20A-20E shows representative analytical HPLC profiles of the peptides (C-18 Vydac column-250×4.6 mm; solvent system was a gradient of water/acetonitrile (0.1% TFA), 35-70% in 12 minutes).

Example 5: Effect of Fatty Acid Containing Peptides in ApoE Null Mice

The effects of synthetic ApoE-mimicking peptides comprising a fatty acid moiety at the N-terminus of the peptide on plasma cholesterol are shown in FIGS. 21-31.
