Abstract
The invention relates to methods for treating metabolic disorders, including diabetes by using a combination of an acylated glucagon analogue and an insulin analogue. The invention also features a kit that includes an acylated glucagon analogue and an insuline analogue.
Description
The présent invention relates to combinations of an acylated glucagon analogue with an insulin analogue and their medical use, for example, in the treatment of obesity and diabètes.
BACKGROUND OF THE INVENTION
Obesity and diabètes are globally increasing health problems and are associated with various diseases, particularly cardiovascular disease (CVD), obstructive sleep apnea, stroke, peripheral artery disease, microvascular complications and osteoarthritis.
There are 246 million people worldwide with diabètes, and by 2025 it is estimated that 380 million will hâve diabètes. Many hâve additional cardiovascular risk factors including high/aberrant LDL and triglycérides and low HDL.
Cardiovascular disease accounts for about 50% of the mortality in people with diabètes and the morbidity and mortality rates relating to obesity and diabètes underscore the medical need for efficacious treatment options.
Preproglucagon is a 158 amino acid precursor polypeptide that is differentially processed in the tissues to form a number of structurally related proglucagon-derived peptides, including glucagon (Glu), glucagon-like peptide-1 (GLP-1), glucagon-like peptide-2 (GLP-2), and oxyntomodulin (OXM). These molécules are involved in a wide variety of physiological functions, including glucose homeostasis, insulin sécrétion, gastric emptying and intestinal growth, as well as régulation of food intake.
Glucagon is a 29-amino acid peptide that corresponds to amino acids 53 to 81 of pre-proglucagon and has the sequence His-Ser-Gin-Gly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-ArgArg-Ala-GIn-Asp-Phe-Val-GIn-Trp-Leu-Met-Asn-Thr. Oxyntomodulin (OXM) is a 37 amino acid peptide which includes the complété 29 amino acid sequence of glucagon with an octapeptide carboxyterminal extension (amino acids 82 to 89 of pre-proglucagon, having the sequence Lys-ArgAsn-Arg-Asn-Asn-lle-Ala and termed “intervening peptide Γ or IP-1 ; the full sequence of human oxyntomodulin is thus His-Ser-GIn-Gly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-ArgArg-Ala-GIn-Asp-Phe-Val-GIn-Trp-Leu-Met-Asn-Thr-Lys-Arg-Asn-Arg-Asn-Asn-lle-Ala). The major biologically active fragment of GLP-1 is produced as a 30-amino acid, C-terminally amidated peptide that corresponds to amino acids 98 to 127 of pre-proglucagon.
Glucagon helps maintaîn the level of glucose in the blood by binding to glucagon receptors on hépatocytes, causing the liver to release glucose - stored in the form of glycogen - through glycogenolysis. As these stores become depleted, glucagon stimulâtes the liver to synthesize addltional glucose by gluconeogenesis. This glucose is released into the bloodstream, preventing the development of hypoglycemia. Additionally, glucagon has been demonstrated to increase lipolysis and decrease body weight.
GLP-1 decreases elevated blood glucose levels by improving glucose-stimulated insulin sécrétion and promûtes weight loss chiefly through decreasing food intake.
Oxyntomodulin is released into the blood in response to food ingestion and in proportion to meal calorie content. The mechanism of action of oxyntomodulin is not well understood. In particular, it is not known whether the effects of the hormone are mediated exclusively through the glucagon receptor and the GLP-1 receptor, or through one or more as-yet unidentifïed receptors.
Other peptides hâve been shown to bind and activate both the glucagon and the GLP-1 receptor (Hjort et al, Journal of Biological Chemistry, 269, 30121-30124,1994) and to suppress body weight gain and reduce food intake (WO 2006/134340; WO 2007/100535; WO 2008/101017, WO 2008/152403, WO 2009/155257 and WO 2009/155258).
Stabilization of peptides has been shown to provide a better pharmacokinetic profile for several drugs. In particular addition of one or more polyethylene glycol (PEG) or acyl group has been shown to prolong half-life of peptides such as GLP-1 and other peptides with short plasma stability.
In WO 00/55184A1 and WO 00/55119 are disclosed methods for acylation of a range of peptides, in particular GLP-1. Madsen et al (J. Med. Chem. 2007, 50, 6126-6132) describe GLP-1 acylated at position 20 (Liraglutide) and provide data on its stability.
Stabilization of OXM by PEGylation and C-terminal acylation has also been shown to improve the pharmacokinetic profile of selected analogues in W02007/100535, W008/071972 and in Endocrinology 2009, 150(4), 1712-1721 by Druce, M R et al.
It has recently been shown that PEGylation of glucagon analogues has a significant effect on the pharmacokinetic profile of the tested compounds (W02008/101017) but also interfères with the potency of these compounds.

DETAILED DESCRIPTION OF THE INVENTION
Throughout this spécification, the conventional one letter and three letter codes for naturally occurring amino acids are used, as well as generally accepted three letter codes for other amino acids, including Aib (α-aminoisobutyric acid), Orn (omithine), Dbu (2,4 diaminobutyric acid) and Dpr (2,3-diaminopropanoic acid).
Unless otherwise indicated, the L-isomeric forms of naturally occurring amino acids are reffered to.
The term “native glucagon refers to native human glucagon having the sequence H-His-Ser-GInGly-Thr-Phe-Thr-Ser-Asp-Tyr-Ser-Lys-Tyr-Leu-Asp-Ser-Arg-Arg-Ala-GIn-Asp-Phe-Val-GIn-Trp-LeuMet-Asn-Thr-OH.
Unless otherwise indicated, the L-isomeric forms of naturally occurring amino acids are referred to. The peptide sequence of a compound employed according to the invention differs from that of native glucagon at least at positions 18, 20, 24, 27, 28 and 29. In addition, it may differ from that of native glucagon at one or more of positions 12, 16 and 17.
Native glucagon has Arg at position 18. The compound employed in accordance with the invention has the small hydrophobie residue Ala at position 18 which is believed to increase potency at both glucagon and GLP-1 receptors but particularly the GLP-1 receptor.
The residues at positions 27, 28 and 29 of native glucagon appear to provide significant selectivity for the glucagon receptor. The substitutions at these positions with respect to the native glucagon sequence, particularly the Ala at position 29, may increase potency at and/or selectivity for the GLP-1 receptor, potentially without significant réduction of potency at the glucagon receptor. Further examples which may be included in the compounds to be employed in the invention include Leu at position 27 and Arg at position 28. Furthermore, Arg at position 28 may be particularly preferred when there is a Glu at position 24 with which it can form an intramolecular bridge, since this may increase its effect on potency at the GLP-1 receptor.
Substitution of the naturally occurring Met residue at position 27 (e.g., with Leu, Lys or Glu) also reduces the potential for oxidation, thereby increasing the chemical stability of the compounds.
Substitution of the naturally-occurring Asn residue at position 28 (e.g., by Arg or Ser) also reduces the potential for deamidation in acidic solution, thereby increasing the chemical stability of the compounds.
Potency and/or selectivity at the GLP-1 receptor, potentially without significant loss of potency at the glucagon receptor, may also be increased by introducing residues that are likely to stabilise an alpha-helical structure in the C-terminal portion of the peptide. It may be désirable, but is not believed essential, for this helical portion of the molécule to hâve an amphipathtc character. Introduction of residues such as Leu at position 12 and/or Ala at position 24 may assist. Additionally or alternatively charged residues may be introduced at one or more of positions 16, 20, 24, and 28. Thus the residues of positions 24 and 28 may ail be charged, the residues at positions 20, 24, and 28 may ail be charged, or the residues at positions 16,20, 24, and 28 may ail be charged. For example, the residue at position 20 may be His or Arg, particularly His. The residue at position 24 may be Glu, Lys or Arg, particularly Glu. The residue at position 28 may be Arg, Introduction of an intramolecular bridge in this portion of the molécule, as discussed above, may also contribute to stabilising the helical character, e.g., between positions 24 and 28.
Substitution of one or both of the naturally-occurring Gin residues at positions 20 and 24 also reduces the potential for deamidation in acidic solution, so increasing the chemical stability of the compounds.
A substitution relative to the native glucagon sequence at position 12 (i.e., of Arg or Leu) may increase potency at both receptors and/or selectivity at the GLP-1 receptor.
C-terminal truncation of the peptide does not reduce potency of both receptors and/or selectivity of the GLP-1 receptor. In particular, truncation of position 29 or truncation of both position 28 and 29 does not reduce the receptor potency to any of the two receptors.
The side chain of one or more of the residues designated X (i.e., positions 16, 17, 20, 24, 27 and 28, and/or 30 if présent) is conjugated to a lipophilie substituent. It will be appreciated that conjugation of the lipophilie substituent to a particular side chain may affect (e.g., reduce) certain of the benefits which the unconjugated side chain may provide at that position. The inventors hâve found that compounds of the invention provide a balance between the benefits of acylation and the benefits of particular substitutions relative to the native glucagon sequence.
Compositions employed in accordance with the invention may further be compounded in, or attached to, for example through covalent, hydrophobie and electrostatic interactions, a drug carrier, drug delivery system and advanced drug delivery system in order to further enhance stability of the compound, increase bioavailability, increase solubility, decrease adverse effects, achieve chronotherapy well known to those skilled in the art, and increase patient compliance or any combination thereof. Examples of carriers, drug delivery Systems and advanced drug delivery Systems include, but are not limited to, polymers, for example cellulose and dérivatives, polysaccharides, for example dextran and dérivatives, starch and dérivatives, poly(vinyl alcohol), acrylate and méthacrylate polymers, polylactic and polyglycolic acid and block co-polymers thereof, polyethylene glycols, carrier proteins, for example albumin, gels, for example, thermogelling Systems, for example block co-polymerîc Systems well known to those skilled in the art, micelles, liposomes, microspheres, nanoparticulates, liquid crystals and dispersions thereof, L2 phase and dispersions there of, well known to those skilled in the art of phase behavlour in lîpid-water Systems, polymeric micelles, multiple émulsions, self-emulsifying, self-microemulsifyïng, cyclodextrins and dérivatives thereof, and dendrimers.
Other groups hâve attempted to prolong the half life of GluGLP-1 dual agonist compounds by derivatisation with PEG (W02008/101017). However such derivatisation appears to be most effective when applied to the C-terminus of the molécule rather than in the central core of the peptide backbone, and potency of these compounds is still decreased compared to the corresponding unmodifîed peptide.
By contrast, the compounds employed in the présent invention retain high potency at both the glucagon and GLP-1 receptors while having significantly protracted pharmacokinetic profiles compared to the corresponding unmodifîed peptides.
Native glucagon has Ser at position 16. Substitution with Ala, Gly or Thr has been shown to reduce adenylate cyclase activation at the glucagon receptor significantly (Unson et al., Proc. Natl. Acad. Sci. 1994, 91,454-458). Hence, derivatisation with a lipophilie substituent at position 16 would not hâve been expected to yield compounds retarning potency at the glucagon receptor, as is surprisingly shown by the compounds described in this spécification. In W02008/101017 a negatively charged residue was found to be désirable at position 16 to minimise loss of potency.
The presence of basic amino acids at positions 17 and 18 is generally believed to be necessary for full glucagon receptor activation (Unson et al., J. Biol. Chem. 1998, 273, 10308-10312). The présent inventors hâve found that, when position 18 is alanine, substitution with a hydrophobie amino acid in position 17 can still yield a highly potent compound. Even compounds in which the amino acid in position 17 is derivatised with a lipophilie substituent retain almost full potency at both glucagon and GLP-1 receptors, as well as displaying a significantly protracted pharmacokinetic profile. This is so even when a lysine at position 17 is derivatised, converting the basic amine side chain into a neutral amide group.
The présent inventors hâve also found that compounds with acylation at position 20 are still highly active dual agonists, despite indications from other studies that substitution in position 20 should be a basic amino acid having a side chain of 4-6 atoms in length to enhance GLP-1 receptor activity compared to glucagon (W02008/101017). The compounds described herein retain both GLP-1 and glucagon receptor activity when position 20 is substituted with lysine and acylated.
Peptide synthesis
The peptide component of the compounds of the invention may be manufactured by standard solid or liquid phase synthetic methods, recombinant expression Systems, or any other suitable method. Thus the peptides may be synthesized in a number of ways including for example, a method which comprises:
(a) synthesizing the peptide by means of solid phase or liquid phase methodology either stepwise or by fragment assembly , isolation and purification of the final peptide product;
(b) expressing a nucleic acid construct that encodes the peptide in a host cell and recovering the expression product from the host cell culture; or (c) effecting cell-free in vitro expression of a nucleic acid construct that encodes the peptide and recovering the expression product;
or any combination of methods of (a), (b), and (c) to obtain fragments of the peptide, subsequently ligating the fragments to obtain the peptide, and recovering the peptide.
It may be preferred to synthesize the analogues of the invention by means of solid phase or liquid phase peptide synthesis. In this context, reference is given to WO 98/11125 and, amongst many others, Fields, GB et al., 2002, “Principles and practice of solid-phase peptide synthesis. In: Synthetic Peptides (2nd Edition) and the examples herein.
Lipophilie substituent
One or more of the amino acid side chains in the compound employed in the invention is conjugated to a lipophilie substituent Z1. Without wishing to be bound by theory, it is thought that the lipophilie substituent binds albumin in the blood stream, thus shielding the compounds of the invention from enzymatic dégradation which can enhance the half-life of the compounds. It may also modulate the potency of the compound, e.g., with respect to the glucagon receptor and/or the GLP-1 receptor.
In certain embodiments, only one amino acid side chain is conjugated to a lipophilie substituent. In other embodiments, two amino acid side chains are each conjugated to a lipophilie substituent. In yet further embodiments, three or even more amino acid side chains are each conjugated to a lipophilie substituent. When a compound contains two or more lipophilie substituents, they may be the same or different.
The lipophilie substituent Z1 may be covalently bonded to an atom in the amino acid side chain, or alternatively may be conjugated to the amino acid side chain by a spacer Z2.
The term ‘‘conjugated is used here to describe the physical attachment of one identifiable chemical moiety to another, and the structural relationship between such moieties. It should not be taken to imply any particular method of synthesis.
The spacer Z2, when présent, is used to provide a spacing between the compound and the lipophilie moiety.
The lipophilie substituent may be attached to the amino acid side chain or to the spacer via an ester, a sulphonyl ester, a thioester, an amide or a sulphonamide. Accordingly it will be understood that preferably the lipophilie substituent includes an acyl group, a sulphonyl group, an N atom, an O atom or an S atom which forms part of the ester, sulphonyl ester, thioester, amide or sulphonamide. Preferably, an acyl group in the lipophilie substituent forms part of an amide or ester with the amino acid side chain or the spacer,
The lipophilie substituent may include a hydrocarbon chain having 10 to 24 C atoms, e.g. 10 to 22 C atoms, e.g. 10 to 20 C atoms. Preferably it has at least 11 C atoms, and preferably it has 18 C atoms or fewer. For example, the hydrocarbon chain may contain 12, 13, 14,15, 16,17 or 18 carbon atoms. The hydrocarbon chain may be linear or branched and may be saturated or unsaturated. From the discussion above it will be understood that the hydrocarbon chain is preferably substituted with a moiety which forms part of the attachment to the amino acid side chain or the spacer, for example an acyl group, a sulphonyl group, an N atom, an O atom or an S atom. Most preferably the hydrocarbon chain is substituted with acyl, and accordingly the hydrocarbon chain may be part of an alkanoyl group, for example a dodecanoyl, 2-butyloctanoyl, tetradecanoyl, hexadecanoyl, heptadecanoyl, octadecanoyl oreicosanoyl group.
As mentioned above, the lipophilie substituent Z1 may be conjugated to the amino acid side chain by a spacer Z2. When présent, the spacer is attached to the lipophilie substituent and to the amino acid side chain. The spacer may be attached to the lipophilie substituent and to the amino acid side chain independently by an ester, a sulphonyl ester, a thioester, an amide or a sulphonamïde. Accordingly, it may include two moieties independently selected from acyl, sulphonyl, an N atom, an O atom or an S atom. The spacer may consist of a linear Cmo hydrocarbon chain or more preferably a linear C^s hydrocarbon chain. Furthermore the spacer can be substituted with one or more substituents selected from alkyl, Ci.6 alkyl amine, Ci.6 alkyl hydroxy and Cv6 alkyl carboxy.
The spacer may be, for example, a residue of any naturally occurring or unnatural amino acid. For example, the spacer may be a residue of Gly, Pro, Ala, Val, Leu, Ile, Met, Cys, Phe, Tyr, Trp, His, Lys, Arg, Gin, Asn, D-Glu, D-Glu, ε-Lys, Asp, Ser, Thr, Gaba, Aib, D-Ala (i.e. 3-aminopropanoyl), 4aminobutanoyl, 5-aminopentanoyl, 6-aminohexanoyl, 7-aminoheptanoyl, 8-aminooctanoyl, 9aminononanoyl, 10-aminodecanoyl or 8-amino-3,6-dioxaoctanoyl. In certain embodiments, the spacer is a residue of Glu, D-Glu, ε-Lys, D-Ala (i.e. 3-aminopropanoyl), 4-aminobutanoyl, 8aminooctanoyl or 8-amino-3,6-dioxaoctanoyl. In the présent invention, D-Glu and isoGlu are used interchangeably.
The amino acid side chain to which the lipophilie substituent is conjugated is a side chain of a Glu, Lys, Ser, Cys, Dbu, Dpr or Orn residue. For example it may be a side chain of a Lys, Glu or Cys residue. Where two or more side chains carry a lipophilie substituent, they may be independently selected from these residues. Thus the amino acid side chain includes an carboxy, hydroxyl, thiol, amide or amine group, for forming an ester, a sulphonyl ester, a thioester, an amide or a sulphonamïde with the spacer or lipophilie substituent.
An example of a lipophilie substituent comprising a lipophilie moiety Z1 and spacer Z2 is shown in the formula below:
Here, the side chain of a Lys residue from the peptide of formula I is covalently attached to an y-Glu spacer (Z2) via an amide lînkage. A hexadecanoyl group (Z1) is covalently attached to the y-Glu spacer via an amide lînkage. This combination of lipophilie moiety and spacer, conjugated to a Lys residue, may be referred to by the short-hand notation K(Hexadecanoyl-y-Glu), e.g., when shown in formulae of spécifie compounds. γ-Glu can also be referred to as isoGlu, and a hexadecanoyl group as a palmitoyl group. Thus it will be apparent that the notation (Hexadecanoyl-y-Glu) is équivalent to the notations (isoGlu(Palm)) or (isoGlu(Palmitoyl)) as used for example in PCT/GB2008/004121.
The skilled person will be well aware of suitable techniques for preparing the compounds employed in the invention. For examples of suitable chemistry, see WO98/08871, WOOO/55184, WOOO/55119, Madsen et al (J. Med. Chem. 2007, 50, 6126-32), and Knudsen étal. 2000 (J. Med Chem. 43,1664-1669).
PEGylated and/or acylation hâve a short half-life (T%), which gives rise to burst increases of GluGLP-1 agonist concentrations. The glucagon receptor is thus being subjected to burst exposure to the glucagon agonism once (or twice) daily throughout the treatment period.
Without being bound to any theory repeated burst exposure of GluR to glucagon agonism seems to bring havoc to the lipid and free fatty acid trafficking between the liver and adipose tissue with the resuit that fat accumulâtes in the liver.
Constant exposure of GluR to glucagon agonism blocks accumulation of fat in the liver
It has thus been found, that repeated treatment with glucagon or short acting dual GluGLP-1 agonists give rise to enlarged liver due to fat and glycogen accumulation (Chan et al., 1984. Exp. Mol. Path. 40, 320-327).
Repeated treatment with long-actrng acylated dual GluGLP-1 agonists do not give rise to change in liver size (enlarged or shrunken) in normal weight subjects, but normalize liver lipid content (Day et al., 2009; Nat.Chem.Biol. 5, 749 - 57).
Efficacy
Binding of the relevant compounds to GLP-1 or glucagon (Glu) receptors may be used as an indication of agonist activity, but in general it is preferred to use a biological assay which measures intracellular signalling caused by binding of the compound to the relevant receptor. For example, activation of the glucagon receptor by a glucagon agonist will stimulate cellular cyclic AMP (cAMP) formation. Similarly, activation of the GLP-1 receptor by a GLP-1 agonist will stimulate cellular cAMP formation. Thus, production of cAMP in suitable cells expressing one of these two receptors can be used to monitor the relevant receptor activity. Use of a suitable pair of cell types, each expressing one receptor but not the other, can hence be used to détermine agonist activity towards both types of receptor.
The skilled person will be aware of suitable assay formats, and examples are provided below. The GLP-1 receptor and/or the glucagon receptor may hâve the sequence of the receptors as described in the examples. For example, the assays may make use the human glucagon receptor (GlucagonR) having primary accession number Gl: 4503947 (NP_000151.1 ) and/or the human glucagon-like peptide 1 receptor (GLP-1 R) having primary accession number Gl:166795283 (NP_002053.3). (Where sequences of precursor proteins are referred to, it should of course be understood that assays may make use of the mature protein, lacking the signal sequence).
ECm values may be used as a numerical measure of agonist potency at a given receptor. An ΕΟ50 value is a measure of the concentration of a compound required to achieve half of that compound's maximal activity in a particular assay. Thus, for example, a compound having ΕΟ50 [GLP-1 R] lower than the EC50 [GLP-1 R] of native glucagon in a particular assay may be considered to hâve higher potency at the GLP-1 R than glucagon.
The compounds described in this spécification are typically Glu-GLP-1 dual agonists, i.e,, they are capable of stimulating cAMP formation at both the glucagon receptor and the GLP-1 R. The stimulation of each receptor can be measured in independent assays and afterwards compared to each other.
By comparing the EC50 value for the glucagon receptor (EC50 [Glucagon-R]) with the ECso value for the GLP-1 receptor (ECæ [GLP-1 R]) for a given compound the relative glucagon selectivity (%) of that compound can be found:
Relative Glucagon-R selectivity [Compound] = (1/ECso [Glucagon-R])x100% / (I/EC50 [Glucagon-R] + 1/ECSo [GLP-1 R])
The relative GLP-1 R selectivity can likewise be found:
Relative GLP-1 R selectivity [Compound] = (1/ECm [GLP-1 R])x100% / (1/ECsq [Glucagon-R] + 1/ECS0 [GLP-1 R])
A compound’s relative selectivity allows its effect on the GLP-1 or glucagon receptor to be compared directly to its effect on the other receptor. For example, the higher a compound’s relative GLP-1 selectivity is, the more effective that compound is on the GLP-1 receptor as compared to the glucagon receptor.
Using the assays described below, we hâve found the relative GLP-1 selectivity for human glucagon to be approximately 5%.
The compounds employed in the invention hâve a higher relative GLP-1 R selectivity than human glucagon. Thus, for a particular level of glucagon-R agonist activity, the compound will display a higher level of GLP-1 R agonist activity (i.e., greater potency at the GLP-1 receptor) than glucagon. It will be understood that the absolute potency of a particular compound at the glucagon and GLP-1 receptors may be higher, lower or approximately equal to that of native human glucagon, as long as the appropriate relative GLP-1 R selectivity is achieved.
Nevertheless, the compounds employed in this invention may hâve a lower ECS0 [GLP-1 R] than human glucagon. The compounds may hâve a lower ECso [GLP-1 R] than glucagon while maintaîning an EC50 [Glucagon-R] that is less than 10-fold higher than that of human glucagon, less than 5-fold higher than that of human glucagon, or less than 2-fold higher than that of human glucagon.
It may be désirable that ECSo of any given compound for both the Glucagon-R and GLP-1 R should be less than 1 nM.
The compounds employed in the invention may hâve an ECso [Glucagon-R] that is less than twofold that of human glucagon. The compounds may hâve an EC50 [Glucagon-R] that is less than two-fold that of human glucagon and hâve an EC» [GLP-1 R] that is less than half that of human glucagon, less than a fifth of that of human glucagon, or less than a tenth of that of human glucagon.
The relative GLP-1 selectivity of the compounds may be greater than 5% and less than 95%. For example, the compounds may hâve a relative selectivity of 5-20%, 10-30%, 20-50%, 30-70%, or 50-80%, or of 30-50%, 40-60%, 50-70% or 75-95%.
Improvinq circulating glucose levels, glucose tolérance or circulating cholestérol levels Normal blood sugar levels fluctuate depending on duration after last meal. A normal blood glucose level range for fasting individuals should be below 100 mg/dl and their level should be below 130140 mg/dl or so around an hour after eating.
Ideally the fasting blood glucose levels should be around 90 mg/dl. Diabètes are diagnosed when fasting blood glucose levels are approaching 120 mg/dl or higher.
Blood sugar levels outside the normal range may be an indicator of a medical condition. A persistently high level is referred to as hyperglycemia; low levels are referred to as hypoglycemia. Diabètes mellitus is characterized by persistent hyperglycemia from any of several causes, and is the most prominent disease related to failure of blood sugar régulation. A temporarily elevated blood sugar level may also resuit from severe stress, such as trauma, stroke, myocardial infarction, surgery, or illness. Intake of alcohol causes an initial surge in blood sugar, and later tends to cause levels to fall. Also, certain drugs can increase or decrease glucose levels.
If blood sugar levels drop too low, a potentially fatal condition called hypoglycemia develops. Symptoms may include lethargy, impaired mental functioning; irritability; shaking, twitching, weakness in arm and leg muscles; pale complexion; sweating; paranoid or aggressive mentality and loss of consciousness. Brain damage is even possible.
If levels remain too high, appetite is suppressed over the short term. Long-term hyperglycémie causes many of the long-term health problems associated with diabètes, including eye, kidney, heart disease and nerve damage.
Type 1 diabètes is a lifelong condition that can be controlled with lifestyle adjustments and medical treatments. Keeping blood glucose levels under control can prevent or minimïze complications. Insulin treatment is one component of a diabètes treatment plan for people with type 1 diabètes.
Insulin treatment replaces or suppléments the body's own insulin, restoring normal or near-normal blood sugar levels. Many different types of insulin treatment can successfully control blood sugar levels: the best option dépends upon a variety of individual factors. With a little extra planning, people with diabètes who take insulin can lead a full life and keep their blood sugar under control.
The central problem for those requiring external insulin is picking the right dose of insulin and the right timing.
Physiological régulation of blood glucose, as in the ηοπ-diabetic, would be best. Increased blood glucose levels after a meal is a stimulus for prompt release of insulin from the pancréas. The increased insulin level causes glucose absorption and storage in cells, reduces glycogen to glucose conversion, reducing blood glucose levels, and so reducing insulin release. The resuit is that the blood glucose level rises somewhat after eating, and within an hour or so, returns to the normal ’fasting' level. Even the best dîabetic treatment with synthetic human insulin or even insulin analogs, however administered, falls far short of normal glucose control in the non-diabetic.
Complicating matters is that the composition of the food eaten affects intestinal absorption rates. Glucose from some foods is absorbed more (or less) rapidly than the same amount of glucose in other foods. In addition, fats and proteins cause delays in absorption of glucose from carbohydrates eaten at the same time.
It is a well known fact that insulin causes weight gain in patients with type 2 diabètes. Insulin is a hormone secreted by the pancréas in response to glucose intake usually in the diet. Its rôle is to drive glucose into the cells of the body where it is used as a source of energy (measured in calories). Insulin therefore pumps calories into cells. If this energy (glucose) is not used by the cells or is more than is needed, it is converted into an energy storage form known as fat. Because of these actions insulin is called an anabolic hormone.
The word “anabolic means building up tissue. If a person is using his or her muscles and is physically active, the extra energy is converted into new (larger and/or stronger) muscles rather than fat. In a sense, a person who is sedentary, not using his muscles, getting more calories than he needs and taking insulin is in the midst of a “perfect (metabolîc) storm that will resuit in weight gain. The issue of insulin causing weight gain has long been a troubling aspect of the treatment for type 2 diabètes. It is not a problem in type 1 diabètes where patients have virtualJy no circulating insulin and need to receive it from an external source.
In type 2 diabètes the physiology is quite different. Here the body does make insulin, but the tissues are “résistant to its effects, In fact, in the early stages of type 2 diabètes insulin levels can actually be high. This occurs because the tissues are résistant to insulin and higher insulin levels become necessary to drive sugar (glucose) into the cells and thereby drop the sugar level in the blood. The cause of insulin résistance is complex and is still a very active area of research. It appears that a certain type of fat tissue, fat that is contained in the abdomen (also called viscéral adipose tissue), produces certain hormones and other substances that together cause insulin résistance. This was a major surprise in medicine when it was discovered only 10 or 15 years ago. Prior to that fat tissue was considered to be “metabolically inert, which means that it was just a storage tissue and didn’t affect metabolism. This was very far from the truth and viscéral fat Is now considered to be very active and complex metabolically. It produces a host of hormones (for example leptin, ghrelin and adiponectin) and other factors (cytokines) that have major influences on metabolism.
The discovery that insulin résistance was the central “lésion in type 2 diabètes led to a whole area of research that resulted in linking type 2 diabètes to high blood pressure, truncal or abdominal obesity, abnormal blood lipids (elevated triglycérides and low HDL cholestérol) and high waist to hip ratio (the “apple” body type).
Using insulin to treat type 2 diabètes is problematic. The person with type 2 diabètes is usually overweight and circulating insulin levels may already be high. Adding additional insulin will certainly cause weight gain and this can actually make the insulin résistance worse. The usual justification is that using insulin will protect the remarning insulin-producing beta cells in the pancréas from having to work overtime. However, only a few months ago this issue was reviewed by one of the leading diabètes authorities in the world: Dr. Ralph DeFronzo. DeFronzo recently gave the prestigious Banting Lecture and it was published in the April 2009 issue of Diabètes. DeFronzo suggests that the American Diabètes Association guidelines for treatment of type 2 diabètes may be misguided and in need of révision.
Regarding insulin-induced weight gain, he notes that when insulin is added to the treatment regimen, “ali of these insulin-based add-on studies have been associated with a high incidence of 28 hypoglycemia [low blood sugar] and major weight gain (range 4.2-19.2 Ibs, mean 8.5 Ibs within 612 months or less)....Moreover it is unclear why one would initiate insulin before exenatide [a newer non-insulin drug] since insulin rarely decreases A1C to <7% and is associated with significant weight gain... (Diabètes, Journal ofthe American Diabètes Association, April 2009, vol 58(4), page 786).Other potentially serious side-effects and related long term complications often associated with insulin treatment are well known. In particular, risk of developing hypoglycemia, allergy, résistance, and edema and related insulin side effects are well known short and longerterm side-effects of insulin treatment.
Glu-GLP-1 dual agonists of the présent invention activâtes the GLP-1 receptor, a membrane-bound cell-surface receptor coupled to adenylyl cyclase by the stimulatory G-protein, Gs, in pancreatic beta cells. Glu-GLP-1 dual agonists of the présent invention increases intracellular cyclic AMP (cAMP), leading to insulin release in the presence of elevated glucose concentrations. This insulin sécrétion subsides as blood glucose concentrations decrease and approach euglycemia, Glu-GLP1 dual agonists of the présent invention also decreases glucagon sécrétion in a glucose-dependent manner. The mechanism of blood glucose lowering also involves a delay in gastric emptying. GLP-1 (7-37) has a half-life of 1.5-2 minutes due to dégradation by the ubiquitous endogenous enzymes, dipeptidyl peptidase IV (DPP-IV) and neutral endopeptidases (NEP). Unlike native GLP1, Glu-GLP-1 dual agonists ofthe présent invention are stable against metabolic dégradation by both peptidases and has a prolonged plasma half-life after subcutaneous administration. The pharmacokinetic profile of Glu-GLP-1 dual agonists of the présent invention, which makes them suitable for once daily administration, is a resuit of self-association that delays absorption, plasma protein binding and stability against metabolic dégradation by DPP-IV and NEP.
Combination of Glu-GLP-1 dual agonists of the présent invention with insulin may hâve advantages over current type2 diabètes thérapies:
. The combination acts in a glucose-dependent manner, meaning it will stimulate insulin sécrétion only when blood glucose levels are higher than normal. Consequently, it shows negligîble risk of hypoglycemia.
• The combination has the potential for inhibiting apoptosis and stimulating régénération of beta cells (seen in animal studies).
• The combination decreases appetite and maintains body weight, as shown in a head-tohead study versus glimepiride.
• The combination lowers blood triglycéride levels.
• The combination has only mild and transient side effects, mainly gastrointestinal
For treatment of type 2 diabètes condition and in partîcular late stage type 2 diabètes condition, use of Glu-GLP-1 dual agonists in combination with insulin may further improve e.g. normalize circulating glucose levels, glucose tolérance or circulating cholestérol levels.
In one embodiment, the présent invention is directed to treatment of diabètes melitus where a GluGLP-1 dual agonists of the présent invention is co-administred with an insulin to improve the circulating glucose levels, glucose tolérance or circulating cholestérol levels.
In another embodiment, the présent invention is directed to treatment of type 2 diabètes where a Glu-GLP-1 dual agonists of the présent invention is co-administred with an insulin to improve the circulating glucose levels, glucose tolérance or circulating cholestérol levels.

The methods, kits, and compounds of the invention may use any insulin analogue known in the art.
Such insulin analogues comprise wild type insulin molécules, preferably of human genetic origin, as well as those which are modified chemically, e.g. by the exchange of single amino acids and/or the addition of side chains and/or the coupling with one or more medium sized molécules or polymers. Such insulin analogues also comprise compositions of such non-modified or modified insulins with other chemical substances which make them apt e.g. for the incorporation into spécifie medical compositions and/or mixtures with other insulin analogues.
In the context of this invention, human wildytype insulin is preferably produced recombinantly, which technique is per se known to the person skilled in the art. Such recombinant human insulins are also called Normal insulin.

Therapeutic uses
The methods, kits, and compounds of the invention may provide an attractive treatment option for metabolic diseases including obesity and diabètes mellitus (diabètes).
Diabètes comprises a group of metabolic diseases characterized by hyperglycemia resulting from defects in insulin sécrétion, insulin action, or both. Acute signs of diabètes include excessive urine production, resulting compensatory thirst and increased fluid intake, blurred vision, unexplained weight loss, lethargy, and changes in energy metabolism. The chronic hyperglycemia of diabètes is associated with long-term damage, dysfunction, and failure of various organs. notably the eyes, kidneys, nerves, heart and blood vessels. Diabètes is classified into type 1 diabètes, type 2 diabètes and gestational diabètes on the basis on pathogenetic characteristics.
Type 1 diabètes accounts for 5-10% of ail diabètes cases and is caused by auto-immune destruction of insulin-secreting pancreatic β-cells.
Type 2 diabètes accounts for 90-95% of diabètes cases and is a resuit of a complex set of metabolic disorders. Type 2 diabètes is the conséquence of endogenous insulin production becoming insufficient to maintain plasma glucose levels below the diagnostic thresholds.
Gestational diabètes refers to any degree of glucose intolérance identifîed during pregnancy.
Pre-diabetes includes impaired fasting glucose and impatred glucose tolérance and refers to those states that occur when blood glucose levels are elevated but below the levels that are established for the clinical diagnosis for diabètes.
A large proportion of people with type 2 diabètes and pre-diabetes are at increased risk of morbidity and mortality due to the high prevalence of additional metabolic risk factors including abdominal obesity (excessive fat tissue around the abdominal internai organs), atherogenic dyslipidemia (blood fat disorders including high triglycérides, low HDL cholestérol and/or high LDL cholestérol, which foster plaque buildup in artery walls), elevated blood pressure (hypertension) a prothrombotic state (e.g., high fibrinogen or plasminogen activator inhibitor—1 in the blood), hypertriglyceridemia, hypercholesterolemia and proinflammatory state (e.g., elevated C-reactive protein in the blood).
Conversely, obesity confers an increased risk of developing pre-diabetes, type 2 diabètes as well as, e.g., certain types of cancer, obstructive sleep apnea and gall-blader disease.
Dyslipidaemia is associated with increased risk of cardîovascular diasese. High Density Lipoprotein (HDL) is of clinical importance since an inverse corrélation exists between plasma HDL concentrations and risk of atherosclerotic disease. The majority of cholestérol stored in atherosclerotic plaques originates from LDL and hence elevated concentrations Low Density Lipoproteins (LDL) is closely associated with atherosclerosis. The HDL/LDL ratio is a clinical risk indictor for atherosclerosis and coronary atherosclerosis in partîcular.
Without wishing to be bound by any partîcular theory, it is believed that the compounds employed in the invention act as GluGLP-1 dual agonists. The dual agonist may combine the effect of glucagon, e.g., on fat metabolism with the effect of GLP-1, e.g., on blood glucose levels and food intake. They might therefore act to accelerate élimination of excessive adipose tissue, induce sustainable weight loss, and improve glycaemic control. Dual GluGLP-1 agonists might also act to 45 reduce cardiovascular risk factors such as high cholestérol and LDL-cholesterol. Dual GluGLP-1 agonists might also act to reduce circulating triacylglycerol levels and lowering circulating free fatty acids.
The compounds employed in the présent invention can therefore be used as pharmaceutical agents for preventing weight gain, promoting weight loss, reducing excess body weight or treating obesity (e.g., by control of appetite, feeding, food intake, calorie intake, and/or energy expenditure), including morbid obesity, as well as associated diseases and health conditions including but not limited to obesity linked inflammation, obesity linked gallbladder disease and obesity induced sleep apnea. The compounds employed in the invention may also be used for treatment of insulin résistance, glucose intolérance, pre-diabetes, increased fasting glucose, type 2 diabètes, hypertension, dyslipidemia (or a combination of these metabolîc risk factors), atherosclerois, arteriosclerosis, coronary heart disease, peripheral artery disease and stroke. These are ail conditions which can be associated with obesity. However, the effects of the compounds of the invention on these conditions may be mediated in whole or in part via an effect on body weight, or may be independent thereof.

Animais
Eighty (80) db/db (BKS.Cg-m +/+ Lepr^/S) female mice aged 7 weeks were obtained from Charles River, US. The mice were acclimatized in their new environment and ailowed free access to normal chow (Altromin 1324, Brogaarden A/S, Gentofte, Denmark) and domestic quality tap water added citric acid to pH -3.6, except as indicated. The mice were group-housed with 3-4 mice per 1 The équation used to calculate the molar équivalents of peptide is: npepHdB = (mlyophliwa canpound * (% purity/100) * (% peptide content/lOOfj/MWpgpwv· cage in a light-, température-, and humidity-controlled room (12-hour light: 12-hourdark cycle, with lights on at 06.00 AM to 06.00 PM hour; 24°C; 50% relative humidity).
Procedure
Pre-screen
Prior to treatment, in weeks 1-3, a tail-blood sample for the détermination of blood glucose was obtained on non-fasted animais to détermine diabetic state and to identify outliers, which were excluded. The inclusion criteria of BG > 16 mM glucose was applied,
Stratification
Stratification of the animais was based on HbA1c levels (primary) and BW as measured at baseline (day -4). Thus, on day -3, the 66 mice were selected based on the pre-screen and baseline measurements into 6 study groups of 11 mice (3-4 mice/cage).
Dosing, body weight, food, and water intake
Ail mice were mock treated for at 3 days (BID, SC, 100 μΙ vehicle) to acclimatize the animais to handling and injections. Dosing (day 0, mice at âge 12 weeks as in pilot study) started in the afternoon on that day, and the mice were treated twice daily with 2 SC injections according to Table 1 for a total of 21 days (4 injections per day). Thus, last day of dosing was day 21 in the morning. The daily injections took place between 7:00 and 8:00 and between 14:00 and 15:00 with fresh solutions prepared in the morning (only Compound X). Insulin was kept in the refrigerator.

Dosing solutions of Compound X for the weekend were prepared the Friday before. One vial was prepared for every dosing. Injection volume (Compound X or PBS): 5 ml/kg. Throughout the study (day -2 to day 21 ) body weights (BW) were recorded daily and used to administer the body weightcorrected doses of substances. Food and water intake (Fl, Wl) was measured every day (day -3 to day 21 ) as cage averages.
Blood samples
On day -4 (before starting treatment) in 8h fasted mice, a blood sample (150 μΙ) was obtained from the orbital plexus using an EDTA coated micro-pipette taken into EDTA coated tubes kept on ice. From that sample, a drop was used for analysis of blood glucose (BG) (sticks).
Also, 30 μΙ sample of blood was transferred to a new tube fortesting of HbA1c. Stored samples for HbA1c analysis were kept at 4 °C for no more than 48 hours before analysis. The remaining blood was centrifuged, and the resulting plasma (approximately 50 μΙ) was stored (at -80°C) for later analysis of plasma insulin level.
On day 21 (before termination) in 8h fasted mice a blood sample (350 μΙ) was taken, and BG, HbA1c, and p-insulin were measured as described above. In addition a plasma sample (at least 100 μI) was stored (at -80°C) for later analysis of exposure.
Termination
The study was terminated on day 21. Ail animais were sacrificed immediately following the last blood sampling by CO2 anesthésia followed by cervical dislocation.
Analysis
The whole blood glucose level was analyzed on tail-blood samples by the immobilized glucose oxidase method (Elite Auto analyser, Bayer, Denmark) following the manufacturées protocol. Blood samples (sample size 30 pl) were analyzed for HbA1c using the Cobas c111 analyzer (Roche Diagnostics, Mannheim, Germany) in single déterminations by Department of Molecular Pharmacology. Plasma (sample size 5 μΙ) and insulin content was measured using an insulin alpha-LISA assay in triplicate by Department of Molecular Pharmacology. A measure of peptide exposure in plasma (sample size 100 μΙ) will be determined by the Department of Bioanalysis and Pharmacokinetics.
Data analysis
Statistical analyses will be performed using GraphPad Prism version 5. The measured parameters will be compared using a one way and/or two-way ANOVA and relevant post-hoc analyses will be conducted. Différences will be considered statistically significant at p < 0.05. Possible outliers will be evaluated by Grubbs outlier test.
Génération of cell lines expressinq human qlucaqon- and GLP-1 receptors
The cDNA encoding either the human glucagon receptor (Glucagon-R) (primary accession number P47871) orthe human glucagon-like peptide 1 receptor (GLP-1 R) (primary accession number P43220) were cloned from the cDNA clones BC104854 (MGC:132514/lMAGE:8143857) or BC112126 (MGC:138331/IMAGE:8327594), respectively. The DNA encoding the Glucagon-R or the GLP-1 R was amplified by PCR using primers encoding terminal restriction sites for subcloning. The 5'-end primers additionally encoded a near Kozak consensus sequence to ensure efficient translation. The fidelity of the DNA encoding the Glucagon-R and the GLP-1 R was confirmed by DNA sequencing. The PCR products encoding the Glucagon-R or the GLP-1 R were subcloned into a mammalian expression vector containing a neomycin (G418) résistance marker.
The mammalian expression vectors encoding the Glucagon-R or the GLP-1 R were transfected into HEK293 cells by a standard calcium phosphate transfection method. 48 hr after transfection cells were seeded for limited dilution cloning and selected with 1 mg/ml G418 in the culture medium. Three weeks later 12 surviving colonies of Glucagon-R and GLP-1 R expressing cells were picked, propagated and tested in the Glucagon-R and GLP-1 R efficacy assays as described below. One Glucagon-R expressing clone and one GLP-1 R expressing clone were chosen for compound profiling.
Glucagon receptor and GLP-1 Receptor efficacv assays
HEK293 cells expressing the human Glucagon-R, or human GLP-1 R were seeded at 40,000 cells per well in 96-well microtiter plates coated with 0.01 % poly-L-lysine and grown for 1 day in culture in 100 pl growth medium. On the day of analysis, growth medium was removed and the cells washed once with 200 μΙ Tyrode buffer. Cells were incubated in 100 μΙ Tyrode buffer containing increasing concentrations of test peptides, 100 μΜ IBMX, and 6 mM glucose for 15 min at 37° C. The reaction was stopped by addition of 25 μΙ 0.5 M HCl and incubated on ice for 60 min. The cAMP content was estimated using the FlashPIate® cAMP kit from Perkin-Elmer. EC5q and relative efficacies compared to reference compounds (glucagon and GLP-1) were estimated by computer aided curve fitting.
In Vivo: female db/db mice aged 10-11 weeks were treated for 21 days with bi-daily s.c. injections. Groups: vehicle (PBS), Lantus (3U), Levemir{6U), COMPOUND X (10nmol/kg), Lantus (3U)+COMPOUND X (10nmol/kg), Levemir (6U)+COMPOUND X (10nmol/kg). Fasting blood glucose (BG) was measured before and after 21 days of treatment.
EXAMPLES
Example 1: Réduction of weight gain by the compound Compound X in mice receiving insulin analogues
As shown in Figure 1, we observed a significant increase in body weight in mice treated with either Lantus or Levemir, while treatment with Compound X caused a significant decrease in BW.
Interestingly, BW in mice treated with both Compound X and Lantus or Levemir was similar to that of vehicle control. Our results indicate that combination of a long-acting insulin and GluGLP-1 dual agonist Compound X may improve glycémie control while avoiding the undesirable weight gain of conventional insulin treatment, or promote a overall weight-loss while improving glycémie control.
Food intake was reduced in mice receiving Compound X in combination with either Lantus or Levemir as compared to mice receiving Lantus or Levemir alone alone, as shown in Figure 2. Similarly, intake of water in mice receiving Compound X combination with either Lantus or Levemir was reduced, as compared to mice receiving either Latnus or Levemire alone. These results are shown in Figure 3.
Example 2: Efficacy on GLP-1 and Glucagon receptors
Figure 4 shows the delta-BG. When mice were treated with Lantus alone or in combination with the glucagon-GLP-1 dual agonist Compound X, in contrast to vehicle control we observed a decrease in delta-BG over the course of the 21-day experiment (mM, -9.6±1.9 vs. -10.9±1.1, Lantus vs.
Lantus+ Compound X; p=ns). In animais treated with Levemir, we also observed a decrease in delta-BG, which was more pronounced when combined with Compound X (mM, -2.1 ±1.6 vs. 9.8±2.8, Levemir vs. Levemir+ Compound X, p<0.05).
