`
`FIELD OF THE INVENTION
`
`This invention relates to the field of therapeutic peptides,
`i.e. to new protracted GLP-1 compounds.
`
`BACKGROUND OF THE INVENTION

`
`35
`
`A range of different approaches have been used for modi
`fying the structure of glucagon-like peptide 1 (GLP-1) com
`pounds 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.
`WO98/08871 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.
`WO 00/699.11 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.
`Many diabetes patients particularly in the type 2 diabetes
`segment are subject to so-called “needle-phobia’, i.e. a Sub
`stantial 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 administered, the
`fear of injections may become a serious obstacle for the
`widespread use of the clinically very promising GLP-1 com
`pounds. Thus, there is a need to develop new GLP-1 com
`50
`pounds 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.

`The invention provides a method for increasing the time of
`action in a patient of a GLP-1 analog, characterised in acy
`lating said GLP-1 analog with a moiety B U" as disclosed in
`any of the preceding claims, on the lysine residue in position
`26 of said GLP-1 analog.
`
`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 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-carboxyglutamate,
`ornithine, phosphoserine, D-alanine and D-glutamine. Syn
`thetic amino acids comprise amino acids manufactured by
`chemical synthesis, i.e. D-isomers of the amino acids
`encoded by the genetic code such as D-alanine and D-leucine,
`Aib (CL-aminoisobutyric acid), Abu (CL-aminobutyric acid),
`Tle (tert-butylglycine), B-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, Isoleucine, Leucine, Lysine, Methionine,
`Phenylalanine, Proline, 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-ala
`nine and D-glutamine, Synthetic non-proteogenic amino
`acids comprise amino acids manufactured by chemical Syn
`thesis, i.e. D-isomers of the amino acids encoded by the
`genetic code such as D-alanine and D-leucine, Aib (CL-ami
`noisobutyric acid), Abu (CL-aminobutyric acid), Tle (tert-bu
`tylglycine), 3-aminomethyl benzoic acid, anthranilic acid,
`des-amino-Histidine, the beta analogs of amino acids such as
`B-alanine etc. D-histidine, desamino-histidine, 2-amino-his
`tidine, B-hydroxy-histidine, homohistidine, N-acetyl-histi
`dine, C-fluoromethyl-histidine, C.-methyl-histidine, 3-py
`ridylalanine,
`2-pyridylalanine
`or
`4-pyridylalanine,
`(1-aminocyclopropyl) carboxylic acid, (1-aminocyclobutyl)
`carboxylic acid, (1-aminocyclopentyl) carboxylic acid,
`(1-aminocyclohexyl) carboxylic acid, (1-aminocycloheptyl)
`carboxylic acid, or (1-aminocyclooctyl) carboxylic acid;
`The term “analogue' as used herein referring to a polypep
`tide means a modified peptide wherein one or more amino
`acid residues of the peptide have been substituted by 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'IGLP
`1 (7-37)Lys designates a GLP-1 (7-37) analogue wherein 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 Gly. Allamino acids
`for which the optical isomer is not stated is to be understood
`to mean the L-isomer. In embodiments of the invention a

`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.
`The term "derivative' as used herein in relation to a peptide
`means a chemically modified peptide oran analogue thereof,
`wherein at least one Substituent is not present in the unmodi
`fied 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 N'-((4S)-4-
`(hexadecanoylamino)-carboxy-butanoyl)|Arg,
`Lys?
`GLP-1-(7-37).
`The term “GLP-1 peptide' as used herein means GLP-1 (7-
`37) (SEQID 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 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 insulino
`tropic 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 (BHK-467-12A) were grown in
`DMEM media with the addition of 100 IU/mL penicillin, 100
`ug/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
`centrifuged at 48,000xg for 15 min at 4°C. The pellet was
`45
`suspended by homogenization in buffer 2 (20 mM HEPES
`Na, 0.1 mM EDTA, pH 7.4), then centrifuged at 48,000xg 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 measur
`ing cyclic AMP (cAMP) as a response to stimulation by the
`insulinotropic agent. cAMP formed was quantified by the
`AlphaScreenTM cAMP Kit (Perkin Elmer Life Sciences).
`Incubations were carried out in half-area 96-well microtiter
`plates in a total volume of 50 uL buffer 3 (50 mM Tris-HCl, 5
`mM HEPES, 10 mM MgCl, pH 7.4) and with the following
`addiditions: 1 mM ATP, 1 uM GTP, 0.5 mM 3-isobutyl-1-
`methylxanthine (IBMX), 0.01% Tween-20, 0.1% BSA, 6 ug
`membrane preparation, 15 ug/mL acceptor beads, 20 g/mL
`60
`donor beads preincubated with 6 nM biotinyl-cAMP. Com
`pounds to be tested for agonist activity were dissolved and
`diluted in buffer 3. GTP was freshly prepared for each experi
`ment. The plate was incubated in the dark with slow agitation
`for three hours at room temperature followed by counting in
`65
`the FusionTM instrument (PerkinElmer Life Sciences). Con
`centration-response curves were plotted for the individual

`
`4
`compounds and ECso values estimated using a four-param
`eter logistic model with Prism v. 4.0 (GraphPad, Carlsbad,
`Calif.).
`The term “DPP-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 (DPP-IV).
`The DPP-IV enzyme in plasma is 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 of the polypeptides Sus
`ceptible to DPP-IV mediated hydrolysis in order to reduce the
`rate of degradation by DPP-IV. In one embodiment a DPP-IV
`protected peptide is more resistant to DPP-IV than GLP-1 (7-
`37) or Exendin-4(1-39).
`Resistance of a peptide to degradation by dipeptidyl ami
`nopeptidase IV is determined by the following degradation
`assay:
`Aliquots of the peptide (5 nmol) are incubated at 37° C.
`with 1 uL of purified dipeptidyl aminopeptidase IV corre
`sponding to an enzymatic activity of 5 mU for 10-180 minutes
`in 100 uL of 0.1 M triethylamine-HCl buffer, pH 7.4. Enzy
`matic reactions are terminated by the addition of 5 uL of 10%
`trifluoroacetic acid, and the peptide degradation products are
`separated and quantified using HPLC analysis. One method
`for performing this analysis is: The mixtures are applied onto
`aVydac C18 widepore (30 nm pores, 5um particles) 250x4.6
`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 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.
`The term "Ce-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-pentyl, isopentyl, neopentyl,
`tert-pentyl, n-hexyl, isohexyl, cyclohexane and the like.
`The term “pharmaceutically acceptable' as used herein
`means Suited for normal 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.
`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 composition is also known
`in the art as a pharmaceutical formulation.
`The term “treatment of a disease' as used herein means the
`management and care of a patient having developed the dis
`ease, 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
