`ACYLATED GLP-1 COMPOUNDS
`
`FIELD OF THE INVENTION
`
`5
`
`This invention relates to the field of therapeutic peptides, i.e. to new protracted GLP-1
`
`compounds.
`
`BACKGROUND OF THE INVENTION
`
`10
`
`A range of different approaches have been used for modifying the structure of glucagon-like
`
`peptide 1 (GLP-1) compounds in order to provide a longer duration of action in vivo.
`
`WO 96/29342 discloses peptide hormone derivatives wherein the parent peptide hormone
`
`has been modified by introducing a lipophilic substituent in the C-terminal amino acid residue
`
`or in the N-terminal amino acid residue.
`
`15 WO 98/08871 discloses GLP-1 derivatives wherein at least one amino acid residue of the
`
`parent peptide has a lipophilic substituent attached.
`
`WO 99/43708 discloses GLP-1 (7-35) and GLP-1 (7-36) derivatives which have a lipophilic
`
`substituent attached to the C-terminal amino acid residue.
`
`WO 00/34331 discloses acylated GLP-1 analogs.
`
`20 WO 00/69911 discloses activated insulinotropic peptides to be injected into patients where
`
`they are supposed to react with blood components to form conjugates and thereby alledgedly
`
`providing longer duration of action in vivo.
`
`WO 02/46227 discloses GLP-1 and exendin-4 analogs fused to human serum albumin in
`
`order to extend in vivo half-life.
`
`25
`
`Many diabetes patients particularly in the type 2 diabetes segment are subject to so-called
`
`"needle-phobia", i.e. a substantial fear of injecting themselves. In the type 2 diabetes
`
`segment most patients are treated with oral hypoglycaemic agents, and since GLP-1
`
`compounds are expected to be the first injectable product these patients will be
`
`30
`
`administered, the fear of injections may become a serious obstacle for the widespread use of
`
`the clinically very promising GLP-1 compounds. Thus, there is a need to develop new GLP-1
`
`compounds which can be administered less than once daily, e.g. once every second or third
`
`day preferably once weekly, while retaining an acceptable clinical profile.

`
`DESCRIPTION OF THE INVENTION
`
`In the present specification, the following terms have the indicated meaning :
`
`The term "polypeptide" and "peptide" as used herein means a compound composed
`
`of at least five constituent amino acids connected by peptide bonds. The constituent amino
`
`acids may be from the group of the amino acids encoded by the genetic code and they may
`
`20
`
`be natural amino acids which are not encoded by the genetic code, as well as synthetic
`
`amino acids. Natural amino acids which are not encoded by the genetic code are e.g., y(cid:173)
`
`carboxyglutamate, ornithine, phosphoserine, D-alanine and O-glutamine. Synthetic amino
`
`acids comprise amino acids manufactured by chemical synthesis, i.e. O-isomers of the amino
`
`acids encoded by the genetic code such as D-alanine and O-leucine, Aib (a-aminoisobutyric
`
`25
`
`acid), Abu (a-aminobutyric acid), Tie (tert-butylglycine), ~-alanine, 3-aminomethyl benzoic
`
`acid, anthranilic acid.
`
`The 22 proteogenic amino acids are:
`
`Alanine, Arginine, Asparagine, Aspartic acid, Cysteine, Cystine, Glutamine, Glutamic acid,
`
`Glycine, Histidine, Hydroxyproline, lsoleucine, Leucine, Lysine, Methionine, Phenylalanine,
`
`30
`
`Praline, Serine, Threonine, Tryptophan, Tyrosine, Valine.
`
`Thus a non-proteogenic amino acid is a moiety which can be incorporated into a peptide via
`
`peptide bonds but is not a proteogenic amino acid. Examples are y-carboxyglutamate,
`
`ornithine, phosphoserine, the D-amino acids such as D-alanine and D-glutamine, Synthetic
`
`non-proteogenic amino acids comprise amino acids manufactured by chemical synthesis, i.e.
`
`35
`
`D-isomers of the amino acids encoded by the genetic code such as D-alanine and O-leucine,

`
`carboxylic acid, (1-aminocycloheptyl) carboxylic acid, or (1-aminocyclooctyl) carboxylic acid;
`
`The term "analogue" as used herein referring to a polypeptide means a modified
`
`peptide wherein one or more amino acid residues of the peptide have been substituted by
`
`10
`
`other amino acid residues and/or wherein one or more amino acid residues have been
`
`deleted from the peptide and/or wherein one or more amino acid residues have been deleted
`
`from the peptide and or wherein one or more amino acid residues have been added to the
`
`peptide. Such addition or deletion of amino acid residues can take place at the N-terminal of
`
`the peptide and/or at the C-terminal of the peptide. A simple system is often used to describe
`analogues : For example [Arg 34]GLP-1 (7-37)Lys designates a GLP-1 (7-37) analogue wherein
`
`15
`
`the naturally occurring lysine at position 34 has been substituted with arginine and wherein a
`lysine has been added to the terminal amino acid residue, i.e. to the Gly37
`
`. All amino acids for
`
`which the optical isomer is not stated is to be understood to mean the L-isomer. In
`
`embodiments of the invention a maximum of 17 amino acids have been modified. In
`
`20
`
`embodiments of the invention a maximum of 15 amino acids have been modified. In

`embodiments of the invention a maximum of 10 amino acids have been modified. In
`
`embodiments of the invention a maximum of 8 amino acids have been modified. In
`
`embodiments of the invention a maximum of 7 amino acids have been modified. In
`
`embodiments of the invention a maximum of 6 amino acids have been modified. In
`
`25
`
`embodiments of the invention a maximum of 5 amino acids have been modified. In
`
`embodiments of the invention a maximum of 4 amino acids have been modified. In
`
`embodiments of the invention a maximum of 3 amino acids have been modified. In
`
`embodiments of the invention a maximum of 2 amino acids have been modified. In
`
`embodiments of the invention 1 amino acid has been modified.
`
`30
`
`The term "derivative" as used herein in relation to a peptide means a chemically modified
`
`peptide or an analogue thereof, wherein at least one substituent is not present in the
`
`unmodified peptide or an analogue thereof, i.e. a peptide which has been covalently
`
`modified. Typical modifications are amides, carbohydrates, alkyl groups, acyl groups, esters
`and the like. An example of a derivative of GLP-1 (7-37) is NE26-((4S)-4-(hexadecanoylamino)-
`, Lys26]G LP-1-(7-37).

`
`The term "GLP-1 peptide" as used herein means GLP-1 (7-37) (SEQ ID No 1 ), a
`
`GLP-1 (7-37) analogue, a GLP-1 (7-37) derivative or a derivative of a GLP-1 (7-37) analogue.
`
`In one embodiment the GLP-1 peptide is an insulinotropic agent.
`
`The term "insulinotropic agent" as used herein means a compound which is an
`
`5
`
`agonist of the human GLP-1 receptor, i.e. a compound which stimulates the formation of
`
`cAMP in a suitable medium containing the human GLP-1 receptor (one such medium
`
`disclosed below). The potency of an insulinotropic agent is determined by calculating the
`
`ECso value from the dose-response curve as described below.
`
`Baby hamster kidney (BHK) cells expressing the cloned human GLP-1 receptor
`
`10
`
`(BHK- 467-12A) were grown in DMEM media with the addition of 100 IU/ml penicillin, 100
`
`µg/ml streptomycin, 5% fetal calf serum and 0.5 mg/ml Geneticin G-418 (Life
`
`Technologies). The cells were washed twice in phosphate buffered saline and harvested with
`
`Versene. Plasma membranes were prepared from the cells by homogenisation with an
`
`Ultraturrax in buffer 1 (20 mM HEPES-Na, 10 mM EDTA, pH 7.4). The homogenate was
`
`15
`
`centrifuged at 48,000 x g for 15 min at 4 ° C. The pellet was suspended by homogenization in
`
`buffer 2 (20 mM HEPES-Na, 0.1 mM EDTA, pH 7.4), then centrifuged at 48,000 x g for 15
`
`min at 4°C. The washing procedure was repeated one more time. The final pellet was
`
`suspended in buffer 2 and used immediately for assays or stored at -80 ° C.
`
`The functional receptor assay was carried out by measuring cyclic AMP (cAMP) as
`
`20
`
`a response to stimulation by the insulinotropic agent. cAMP formed was quantified by the
`
`AlphaScreen™ cAMP Kit (Perkin Elmer Life Sciences). Incubations were carried out in half(cid:173)
`
`area 96-well microtiter plates in a total volume of 50 µL buffer 3 (50 mM Tris-HCI, 5 mM
`
`HEPES, 10 mM MgCl2, pH 7.4) and with the following addiditions: 1 mM ATP, 1 µM GTP, 0.5
`
`mM 3-isobutyl-1-methylxanthine (IBMX), 0.01 % Tween-20, 0.1 % BSA, 6 µg membrane
`
`25
`
`preparation, 15 µg/ml acceptor beads, 20µg/ml donor beads preincubated with 6 nM
`
`biotinyl-cAMP. Compounds to be tested for agonist activity were dissolved and diluted in
`
`buffer 3. GTP was freshly prepared for each experiment. The plate was incubated in the dark
`
`with slow agitation for three hours at room temperature followed by counting in the Fusion™
`
`instrument (Perkin Elmer Life Sciences). Concentration-response curves were plotted for the
`
`30
`
`individual compounds and ECso values estimated using a four-parameter logistic model with
`
`Prism v. 4.0 (GraphPad, Carlsbad, CA).
`The term "OPP-IV protected" as used herein referring to a polypeptide means a
`
`polypeptide which has been chemically modified in order to render said compound resistant to
`
`the plasma peptidase dipeptidyl aminopeptidase-4 (OPP-IV). The OPP-IV enzyme in plasma is
`
`35
`
`known to be involved in the degradation of several peptide hormones, e.g. GLP-1, GLP-2,
`
`Exendin-4 etc. Thus, a considerable effort is being made to develop analogues and derivatives

`
`5
`
`of the polypeptides susceptible to OPP-IV mediated hydrolysis in order to reduce the rate of
`
`degradation by OPP-IV. In one embodiment a OPP-IV protected peptide is more resistant to
`
`OPP-IV than GLP-1 (7-37) or Exendin-4(1-39).
`
`Resistance of a peptide to degradation by dipeptidyl aminopeptidase IV is determined by the
`
`5
`
`following degradation assay :
`
`Aliquots of the peptide (5 nmol) are incubated at 37 QC with 1 µL of purified dipeptidyl
`
`aminopeptidase IV corresponding to an enzymatic activity of 5 mU for 10-180 minutes in 100
`
`µL of 0.1 M triethylamine-HCI buffer, pH 7.4. Enzymatic reactions are terminated by the
`
`addition of 5 µL of 10% trifluoroacetic acid, and the peptide degradation products are
`
`10
`
`separated and quantified using HPLC analysis. One method for performing this analysis is :
`
`The mixtures are applied onto a Vydac C18 widepore (30 nm pores, 5 µm particles) 250 x
`
`4.6 mm column and eluted at a flow rate of 1 ml/min with linear stepwise gradients of
`
`acetonitrile in 0.1 % trifluoroacetic acid (0% acetonitrile for 3 min, 0-24% acetonitrile for 17
`
`min, 24-48% acetonitrile for 1 min) according to Siegel et al., Regul. Pept. 1999;79:93-102
`
`15
`
`and Mentlein et al. Eur. J. Biochem. 1993;214:829-35. Peptides and their degradation
`
`products may be monitored by their absorbance at 220 nm (peptide bonds) or 280 nm
`
`(aromatic amino acids), and are quantified by integration of their peak areas related to those
`
`of standards. The rate of hydrolysis of a peptide by dipeptidyl aminopeptidase IV is estimated
`
`at incubation times which result in less than 10% of the peptide being hydrolysed.
`
`20
`
`The term "C1_5-alkyl" as used herein means a saturated, branched, straight or cyclic
`
`hydrocarbon group having from 1 to 6 carbon atoms. Representative examples include, but
`
`are not limited to, methyl, ethyl, n-propyl, isopropyl, butyl, isobutyl, sec-butyl, tert-butyl, n(cid:173)
`
`pentyl, isopentyl, neopentyl, tert-pentyl, n-hexyl, isohexyl, cyclohexane and the like.
`
`The term "pharmaceutically acceptable" as used herein means suited for normal
`
`25
`
`pharmaceutical applications, i.e. giving rise to no adverse events in patients etc.
`
`The term "excipient" as used herein means the chemical compounds which are normally
`
`added to pharmaceutical compositions, e.g. buffers, tonicity agents, preservatives and the
`
`like.
`
`30
`
`The term "effective amount" as used herein means a dosage which is sufficient to be
`
`effective for the treatment of the patient compared with no treatment.
`
`The term "pharmaceutical composition" as used herein means a product comprising an
`
`active compound or a salt thereof together with pharmaceutical excipients such as buffer,
`
`preservative, and optionally a tonicity modifier and/or a stabilizer. Thus a pharmaceutical

`The term "treatment of a disease" as used herein means the management and care of a
`
`patient having developed the disease, condition or disorder. The purpose of treatment is to
`
`combat the disease, condition or disorder. Treatment includes the administration of the active
`
`compounds to eliminate or control the disease, condition or disorder as well as to alleviate
`
`5
`
`the symptoms or complications associated with the disease, condition or disorder.
`
`In another aspect the present invention relates to an acylated GLP-1 analogue that can bind
`
`to albumin and the GLP-1 receptor simultaneously.
`
`In another aspect the present invention relates to an acylated GLP-1 analogue that bind to
`
`the GLP-1 receptor with an affinity below 1 00nM, preferable below 30 nM in the presence of
`
`10
`
`2% albumin.
`
`In another aspect the present invention relates to an acylated GLP-1 analogue which affinity
`
`to the GLP-1 receptor is only partly decreased when comparing the affinity in the presence of
`
`very low concentration (e.g. 0.005% to 0.2%) of human albumin to the affinity in the presence
`
`of 2% human albumin. The shift in binding affinity under these conditions is less than 50 fold,
`
`15
`
`preferable below 30 fold and more preferable below 10 fold.
`
`The term "albumin binding moiety" as used herein means a residue which binds non-covalently
`
`to human serum albumin. The albumin binding residue attached to the therapeutic polypeptide
`
`typically has an affinity below 10 µM to human serum albumin and preferably below 1 µM. A
`
`20
`
`range of albumin binding residues are known among linear and branched lipohophillic moieties
`
`containing 4-40 carbon atoms having a distal acidic group.
`
`The term "hydrophilic linker" as used herein means a spacer that separates a peptide and an
`
`albumin binding residue with a chemical moiety which comprises at least 5 non-hydrogen
`atoms where 30-50% of these are either Nor 0.
`
`25
`
`The term "acidic groups" as used herein means organic chemical groups which are fully or
`
`partly negatively charged at physiological pH. The pKa value of such groups is below 7,
`
`preferable below 5. This includes but is not limited to carboxylic acids, sulphonic acids,
`
`phosphoric acids or heterocyclic ring systems which are fully or partly negatively charged at
`
`physiological pH.

`
`In the below structural formula II the moiety U is a di-radical may be attached to the terminal
`
`groups B and the aminogroup of the lysine amino acid in the peptide in two different ways. In
`
`embodiments of the invention the U in formula II is attached with the group B attached at the
`
`end of the alkyl chain and the peptide at the other end.
