Definitions

  • the present invention relates to novel compounds that are agonists of the glucagon-like peptide 1 (GLP-1) receptor and the glucose-dependent insulinotropic polypeptide (GIP) receptor with a protracted profile of action, suitable for oral administration to humans.
  • GLP-1 glucagon-like peptide 1
  • GIP glucose-dependent insulinotropic polypeptide
  • Glucagon-like peptide 1 is a gut enteroendocrine cell-derived hormone and one of two prominent endogenous physiological incretins. GLP-1 improves glycemic control by stimulating glucose-dependent insulin secretion in response to nutrients (glucose), inhibits glucagon secretion from the pancreatic alpha-cells, slows gastric emptying, and induces body weight loss primary by decreasing food consumption.
  • Glucose-dependent insulinotropic polypeptide GIP
  • GIP the other prominent incretin, improves glycemic control by stimulation of insulin secretion in response to nutrients (fat, glucose). Furthermore, GIP appears to improve plasma lipid profile and to stimulate calcium accumulation in bones.
  • GIP analogs have been shown to lower body weight and improve glycemic control, though comparatively less potent than GLP-1 analogs to lower body weight in rodent models (Mroz et al, Mol Metab, 2019, 20: 51-62). Moreover, GIP analogs induce body weight loss by additive/synergistic action with GLP-1 analogs in dual administration (Finan et al, Sci Transl Med, 2013, 5 (209): 209ra151; N ⁇ rregaard et al, Diabetes Obes Metab, 2018, 20 (1): 60-68), and as such represent suitable candidates for amplification of GLP-1-based pharmacology.
  • GIPR agonism can be recruited as a non-redundant partner to GLP-1R agonism as a single molecule co-agonist to amplify GLP-1 metabolic benefits, as has been shown in preclinical animal models, most notably body weight loss and glycemic control (Finan et al, Sci Transl Med, 2013, 5 (209): 209ra151; Coskun et al, Mol Metab, 2018, 18: 3-14). Two different peptides with high potency dual incretin receptor agonism have advanced to multi-dose clinical studies.
  • GLP-1 derivatives have been investigated clinically in the form of a once-daily tablet of semaglutide and the permeation enhancer sodium N-[8-(2-hydroxybenzoyl)amino]caprylate (SNAC) (Hedrington & Davis, Exp. Opin. Pharmacother. 2019, 20 (2): 133-141) to improve the very low typical exposure and bioavailability of GLP-1 derivatives following oral administration.
  • SNAC sodium N-[8-(2-hydroxybenzoyl)amino]caprylate
  • GLP-1/GIP co-agonists and their potential medical uses are described in several patent applications such as WO 2010/011439, WO 2013/164483, WO 2014/192284, WO 2015/067715, WO 2015/022420, WO 2015/086728, WO 2015/086729, WO 2016/111971, WO 2020/023386, U.S. Pat. No. 9,745,360, US 2014/162945, and US 2014/0357552.

  • the present invention relates to single molecule co-agonists comprising a peptide and a substituent, which react with both the human GLP-1 and GIP receptors with high potency and are suitable for daily oral administration to humans. This is achieved by the combination of certain peptide sequence variants with substituents via a single site acylation with a diacid based fatty acid.

  • This application is a continuation of U.S. application Ser. No. 17/574,079, filed on Jan. 12, 2022, which is a continuation of International Application No. PCT/EP2021/070485, filed Jul. 22, 2021 and claims priority under 35 U.S.C. § 119 to U.S. Provisional Application 63/156,988, filed Mar. 5, 2021, U.S. Provisional Application 63/055,026, filed Jul. 22, 2020 and European Patent Application 20192414.9, filed Aug. 24, 2020; the contents of which are incorporated herein by reference.
    • TECHNICAL FIELD OF THE INVENTION
  • The present invention relates to novel compounds that are agonists of the glucagon-like peptide 1 (GLP-1) receptor and the glucose-dependent insulinotropic polypeptide (GIP) receptor with a protracted profile of action, suitable for oral administration to humans.
    • INCORPORATION-BY-REFERENCE OF THE SEQUENCE LISTING
  • The instant application contains a Sequence Listing which has been submitted in XML format via the USPTO patent electronic filing system and is hereby incorporated by reference in its entirety. Said XML file, created on Aug. 31, 2022, is named 200018US05.xml and is 98 kilobytes in size.
    • BACKGROUND
  • Glucagon-like peptide 1 (GLP-1) is a gut enteroendocrine cell-derived hormone and one of two prominent endogenous physiological incretins. GLP-1 improves glycemic control by stimulating glucose-dependent insulin secretion in response to nutrients (glucose), inhibits glucagon secretion from the pancreatic alpha-cells, slows gastric emptying, and induces body weight loss primary by decreasing food consumption. Glucose-dependent insulinotropic polypeptide (GIP), the other prominent incretin, improves glycemic control by stimulation of insulin secretion in response to nutrients (fat, glucose). Furthermore, GIP appears to improve plasma lipid profile and to stimulate calcium accumulation in bones. In contrast to GLP-1, the incretin effect of GIP is severely reduced in type 2 diabetes patients, though recent studies suggest that GIP efficiency can be regained in these patients after treatment to improve glucose control. Nonetheless, the role of GIP to regulate systemic metabolism beyond its direct effect at the endocrine pancreas remains controversial, particularly as it relates to GIP action to promote gain in fat mass in animal models. These results have fostered beliefs that GIPR antagonism can improve body weight. Thus, employment of compounds acting at GIP receptors, and specifically whether to agonize or antagonize, as a strategy to improve body weight remains a contentious subject of intense scientific investigation (Finan et al, TRENDS Mol Med, 2016, 22 (5): 359-376; Killion et al, Endo Rev, 2020, 41 (1): 1-21).
  • Protracted GIP analogs have been shown to lower body weight and improve glycemic control, though comparatively less potent than GLP-1 analogs to lower body weight in rodent models (Mroz et al, Mol Metab, 2019, 20: 51-62). Moreover, GIP analogs induce body weight loss by additive/synergistic action with GLP-1 analogs in dual administration (Finan et al, Sci Transl Med, 2013, 5 (209): 209ra151; Nørregaard et al, Diabetes Obes Metab, 2018, 20 (1): 60-68), and as such represent suitable candidates for amplification of GLP-1-based pharmacology. GIPR agonism can be recruited as a non-redundant partner to GLP-1R agonism as a single molecule co-agonist to amplify GLP-1 metabolic benefits, as has been shown in preclinical animal models, most notably body weight loss and glycemic control (Finan et al, Sci Transl Med, 2013, 5 (209): 209ra151; Coskun et al, Mol Metab, 2018, 18: 3-14). Two different peptides with high potency dual incretin receptor agonism have advanced to multi-dose clinical studies. The clinical results have demonstrated improvements in glycemic control and body weight that exceeds what is achieved with comparable dosing of benchmark GLP-1 specific agonists (Frias et al, Cell Metab, 2017, 26 (2): 343-352; Frias et al, Lancet, 2018, 392 (10160): 2180-2193), demonstrating the translational aspects and therapeutic benefits of co-targeting GLP-1 and GIP receptors.
  • Oral delivery of GLP-1 derivatives has been investigated clinically in the form of a once-daily tablet of semaglutide and the permeation enhancer sodium N-[8-(2-hydroxybenzoyl)amino]caprylate (SNAC) (Hedrington & Davis, Exp. Opin. Pharmacother. 2019, 20 (2): 133-141) to improve the very low typical exposure and bioavailability of GLP-1 derivatives following oral administration.
  • GLP-1/GIP co-agonists and their potential medical uses are described in several patent applications such as WO 2010/011439, WO 2013/164483, WO 2014/192284, WO 2015/067715, WO 2015/022420, WO 2015/086728, WO 2015/086729, WO 2016/111971, WO 2020/023386, U.S. Pat. No. 9,745,360, US 2014/162945, and US 2014/0357552. Patent applications disclosing oral delivery of GLP-1 derivatives are described in e.g. WO 2011/080103, WO 2012/080471, WO 2013/189988, and WO 2019/149880.
  • However, no co-agonistic products have so far obtained market approval.
    • SUMMARY
  • The present invention relates to single molecule co-agonists comprising a peptide and a substituent, which react with both the human GLP-1 and GIP receptors with high potency and are suitable for daily oral administration to humans. This is achieved by the combination of certain peptide sequence variants with substituents via a single site acylation with a diacid based fatty acid.

    • GLP-1/GIP Receptor Co-Agonist
  • The present invention relates to compounds that are GLP-1 receptor and the GIP receptor agonists, also referred to as GLP-1/GIP receptor co-agonists or simply co-agonists.
  • The term “compound” is used herein to refer to a molecular entity, and “compounds” may thus have different structural elements besides the minimum element defined for each compound or group of compounds. It follows that a compound may be a peptide or a derivative thereof, as long as the compound comprises the defined structural and/or functional elements.
  • The term “compound” is also meant to cover pharmaceutically relevant forms hereof, i.e. a compound as defined herein or a pharmaceutically acceptable salt, amide, or ester thereof.
  • The term “analogue” generally refers to a peptide, the sequence of which has one or more amino acid changes when compared to a reference amino acid sequence. An “analogue” may also include amino acid elongations in the N-terminal and/or C-terminal positions and/or truncations in the N-terminal and/or C-terminal positions.
  • In general, amino acid residues may be identified by their full name, their one-letter code, and/or their three-letter code. These three ways are fully equivalent.
  • Amino acids are molecules containing an amino group and a carboxylic acid group, and, optionally, one or more additional groups, often referred to as a side chain.
  • The term “amino acid” includes proteinogenic (or natural) amino acids (amongst those the 20 standard amino acids), as well as non-proteinogenic (or non-natural) amino acids. Proteinogenic amino acids are those which are naturally incorporated into proteins. The standard amino acids are those encoded by the genetic code. Non-proteinogenic amino acids are either not found in proteins, or not produced by standard cellular machinery (e.g., they may have been subject to post-translational modification). Non-limiting examples of non-proteinogenic amino acids are Aib (α-aminoisobutyric acid, or 2-aminoisobutyric acid), norleucine, norvaline as well as the D-isomers of the proteinogenic amino acids.

  • As further defined herein below the number of linker elements may be at most 3, referred to as—Z1-Z2-Z3- where Z1 is connected with the protractor (Prot) and the last Z element is connected with the peptide, in which case the substituent may be referred to as Prot-Z1-Z2-Z3-. The symbol*above thus indicates the attachment point to Z1, which when bound via an amide bond is a nitrogen. In an embodiment, where Z1 is a bond (see below), the symbol*indicates the attachment point to the nitrogen of the neighbouring Z element.

The stereoisomerism of the exemplified co-agonists is indicated in the experimental section, in the names as well as the structures, using standard nomenclature. Unless otherwise stated the invention relates to all stereoisomeric forms of the embodied derivative.
    • Functional Receptor Activation Activity
  • The functional activity of the GLP-1/GIP receptor agonists as described herein can be tested in vitro as described herein in Example 2.
  • The term half maximal effective concentration (EO50) generally refers to the concentration which induces a response halfway between the baseline and maximum, by reference to the dose response curve. EC50 is used as a measure of the potency of a compound and represents the concentration where 50% of its maximal effect is observed.
  • The in vitro potency of compounds may thus be determined as described herein and the EC50 determined. The lower the EC50 value, the better the potency.
  • In order to characterize such compounds, it may further be relevant to consider the in vitro potencies relative to the native hormones of each receptor.
  • The in vitro potency may, e.g., be determined in a medium containing membranes expressing the appropriate GLP-1 and/or GIP receptor, and/or in an assay with whole cells expressing the appropriate GLP-1 and/or GIP receptor.
  • For example, the functional response of the human GLP-1 and/or GIP receptor may be measured in a reporter gene assay, e.g. in a stably transfected BHK cell line that expresses the human GLP-1 and/or GIP receptor and contains the DNA for the cAMP response element (CRE) coupled to a promoter and the gene for firefly luciferase (CRE luciferase). When cAMP is produced as a result of activation of the GLP-1 and/or GIP receptor, this in turn results in luciferase being expressed. Luciferase may be determined by adding luciferin, which by the enzyme is converted to oxyluciferin and produces bioluminescence, which is measured as a reporter of the in vitro potency. One example of such an assay is described in Example 2 as described herein. Since the compounds may include a substituent designed to bind albumin, it is also important to note that the receptor activity may be affected by the presence or absence of human serum albumin (HSA) in the assay medium. A decrease in potency of the compound in the presence of HSA, indicated by an increase in EC50 compared to the EC50 in the absence of HSA, indicates interaction of the compounds with HSA and predicts a protracted time of action in vivo.
  • In one embodiment, the compounds have potent in vitro effects to activate the human GLP-1 and GIP receptors.
  • In one embodiment, the compounds are capable of activating the human GLP-1 and GIP receptors in vitro with an EC50 of less than 20 pM in CRE luciferase reporter assays as described in Example 2 herein, when performed without HSA.
  • In one embodiment, the compounds have an in vitro potency at the human GLP-1 and GIP receptors determined using the method of Example 2 corresponding to an EC50 at or below 100 pM, more preferably below 50 pM, or most preferably below 20 pM.
  • In one embodiment, the EC50 in human GLP-1 and GIP receptors assays are both 1-25 pM, such as 1-20 pM, such as 1-15 pM or such as 1-10 pM.
    • Pharmacokinetics Properties
  • The pharmacokinetic properties of the co-agonistic compounds may further be determined in vivo via pharmacokinetic (PK) studies. Animal models such as the mouse, rat, monkey, dog, or pig may be used to perform this characterization.
  • In such studies, animals are typically administered with a single dose of the drug, either intravenously, subcutaneously (s.c.), or orally (p.o.) in a relevant formulation. Blood samples are drawn at predefined time points after dosing, and samples are analysed for concentration of drug with a relevant quantitative assay. Based on these measurements, time-plasma concentration profiles for the compound of study are plotted and a so-called non-compartmental pharmacokinetic analysis of the data is performed. An important parameter is the terminal half-life as a long half-life indicates that less frequent administration of a compound may be possible. The terminal half-life (t½) in vivo may be measured using a suitable model, such as after i.v. administration in minipigs described in Example 3; or after p.o administration in dogs described in Example 4.
  • In one embodiment, the terminal half-life is half-life (t½) in vivo in minipigs after i.v. administration, e.g. as described in Example 3 herein.
  • In one embodiment, the terminal half-life in minipigs is at least 24 hours, such as at least 30 hours, or such as at least 40 hours.
  • In one embodiment, the terminal half-life is half-life (t½) in vivo in dogs after p.o. administration, e.g. as described in Example 4 herein.
  • In one embodiment, the terminal half-life in dogs is at least 24 hours, such as at least 40 hours, or such as at least 50 hours.
    • Pharmaceutically Acceptable Salts
  • In some embodiments, the co-agonists as described herein are in the form of a pharmaceutically acceptable salt. Salts are e.g. formed by a chemical reaction between a base and an acid, e.g.: 2NH3+H2SO4→(NH4)2SO4. The salt may be a basic salt, an acid salt, or it may be neither (i.e. a neutral salt). Basic salts produce hydroxide ions and acid salts hydronium ions in water. The salts of the co-agonists may be formed with added cations or anions between anionic or cationic groups, respectively. These groups may be situated in the peptide and/or in the substituent of the derivatives. Non-limiting examples of anionic groups include any free carboxylic acid groups in the substituent, if any, as well as in the peptide. The peptide may include a free carboxylic acid group at the C-terminus, if present, as well as any free carboxylic acid group of internal acidic amino acid residues such as Asp and Glu.
  • Non-limiting examples of cationic groups include any free amino groups in the substituent, if any, as well as in the peptide. The peptide may include a free amino group at the N-terminus, if present, as well as any free imidazole or amino group of internal basic amino acid residues such as His, Arg, and Lys.
  • In a particular embodiment, the peptide or derivative is in the form of a pharmaceutically acceptable salt.
    • Production Processes
  • The co-agonists may for instance be produced by classical peptide synthesis, e.g. solid phase peptide synthesis using t-Boc or Fmoc chemistry or other well established techniques, see e.g. Greene and Wuts, “Protective Groups in Organic Synthesis”, John Wiley & Sons, 1999; Florencio Zaragoza Dörwald, “Organic Synthesis on Solid Phase”, Wiley-VCH Verlag GmbH, 2000; and “Fmoc Solid Phase Peptide Synthesis”, Edited by W. C. Chan and P. D. White, Oxford University Press, 2000.
  • Alternatively, the compounds may be produced by recombinant methods, e.g. by culturing a host cell containing a DNA sequence encoding the peptide sequence and capable of expressing the peptide, in a suitable nutrient medium under conditions permitting the expression of the peptide. Non-limiting examples of host cells suitable for expression of these peptides are: Escherichia coli, Saccharomyces cerevisiae, as well as mammalian BHK or CHO cell lines.
  • The co-agonists that include non-natural amino acids and/or covalently attached substituents may be produced as described in the experimental part.
  • Specific examples of methods of preparing a number of co-agonists are included in the experimental part.
  • A further aspect of the invention relates to a method for preparing the peptides described herein.
  • A further aspect of the invention relates to a method for preparing the GLP-1/GIP co-agonists described herein.
  • In one embodiment, the method for preparing a compound as described herein comprises a step of solid phase peptide synthesis. The substituent may be built sequentially as part of the solid phase peptide synthesis or produced separately and attached via the lysine residue after peptide synthesis.
  • In one embodiment, the compounds are produced by a two-step process whereby two peptide fragments are ligated after attachment of the substituent to one of the peptide fragments.
    • Pharmaceutical Compositions
  • In a further aspect the invention relates to a pharmaceutical composition comprising a GLP-1/GIP receptor co-agonist as described herein. Compositions comprising the compound or a pharmaceutically acceptable salt hereof, and optionally one or more a pharmaceutically acceptable excipients may be prepared as is known in the art.
  • The term “excipient” broadly refers to any component other than the active therapeutic ingredient(s). The excipient may be an inert substance, an inactive substance, and/or a not medicinally active substance. The excipient may serve various purposes, e.g. as a carrier, vehicle, filler, binder, lubricant, glidant, disintegrant, flow control agent, crystallization inhibitor, solubilizer, stabilizer, coloring agent, flavoring agent, surfactant, emulsifier or combinations thereof and/or to improve administration, and/or to improve absorption of the active substance. The amount of each excipient used may vary within ranges conventional in the art. Techniques and excipients which may be used to formulate oral dosage forms are described in Handbook of Pharmaceutical Excipients (e.g. 8th edition, Sheskey et al., Eds., American Pharmaceuticals Association and Pharmaceutical Press, publications department of the Royal Pharmaceutical Society of Great Britain (2017), and any later editions); and Remington: The Science and Practice of Pharmacy (e.g. 22nd edition, Remington and Allen, Eds., Pharmaceutical Press (2013), and any later editions).
  • In one embodiment, the pharmaceutical composition may be a solid formulation, e.g. a freeze-dried or spray-dried composition, which may be used as is, or whereto the physician or the patient adds solvents, and/or diluents prior to use. In a further embodiment, the pharmaceutical composition may be a solid formulation consisting of the active ingredient, a salt of N-[8-(2-hydroxybenzoyl)amino]caprylate, and one or more further excipients as is known in the art, e.g. using any one or more of the formulations described in WO 2012/080471, WO 2013/189988, or WO 2019/149880.
  • Alternatively, the pharmaceutical composition is a liquid formulation, such as an aqueous formulation. Liquid compositions, suitable for injection, can be prepared using conventional techniques of the pharmaceutical industry which involve dissolving and mixing the ingredients as appropriate to give the desired end product. Thus, according to one procedure, a GLP-1/GIP co-agonist as described herein is dissolved in a suitable buffer at a suitable pH. The composition may be sterilized, for example, by sterile filtration.

  • Methods for solid phase peptide synthesis (SPPS methods, including methods for de-protection of amino acids, methods for cleaving the peptide from the resin, and for its purification), as well as methods for detecting and characterising the resulting peptide (LCMS methods) are described here below.
  • Resins employed for the preparation of C-terminal peptide amides were H-Rink Amide-ChemMatrix resin (loading e.g. 0.5 mmol/g). The Fmoc-protected amino acid derivatives used, unless specifically stated otherwise, were the standard recommended: Fmoc-Ala-OH, Fmoc-Arg(Pbf)-OH, Fmoc-Asn(Trt)-OH, Fmoc-Asp(OtBu)-OH, Fmoc-Cys(Trt)-OH, Fmoc-Gln(Trt)-OH, Fmoc-Glu(OtBu)-OH, Fmoc-Gly-OH, Fmoc-His(Trt)-OH, Fmoc-Ile-OH, Fmoc-Leu-OH, Fmoc-Lys(Boc)-OH, Fmoc-Met-OH, Fmoc-Phe-OH, Fmoc-Pro-OH, Fmoc-Ser(tBu)-OH, Fmoc-Thr(tBu)-OH, Fmoc-Trp(Boc)-OH, Fmoc-Tyr(tBu)-OH, Fmoc-Val-OH, Fmoc-Lys(Mtt)-OH, Fmoc-Aib-OH, etc. supplied from e.g. AAPPTEC, Anaspec, Bachem, Chemlmpex, Iris Biotech, Midwest Biotech, Gyros Protein Technologies or Novabiochem. Where nothing else is specified, the natural L-form of the amino acids are used. The N-terminal amino acid was Boc protected at the alpha-amino group, either by using a reagent with the Boc group pre-installed (e.g. Boc-Tyr(tBu)-OH for peptides with Tyr at the N-terminus) or by exchanging the N-terminal Fmoc protective group for the Boc protective group after installation of the amino acid at the peptide N-terminus.
  • In case of modular albumin binding moiety attachment using SPPS, the following suitably protected building blocks such as but not limited to Fmoc-8-amino-3,6-dioxaoctanoic acid (Fmoc-Ado-OH), Boc-Lys(Fmoc)-OH, Fmoc-Glu-OtBu, hexadecanedioic acid mono-tert-butyl ester, octadecanedioic acid mono-tert-butyl ester, nonadecanedioic acid mono-tert-butyl ester, eicosanedioic acid mono-tert-butyl ester, tetradecanedioic acid mono-tert-butyl ester, or 4-(9-carboxynonyloxy) benzoic acid tert-butyl ester were used. All operations stated below were performed within a 0.1-0.2 mmol synthesis scale range.
  • 1. Synthesis of Resin-Bound Protected Peptide Backbone:
  • Method: SPPS_A
  • SPPS was performed using Fmoc based chemistry on a Protein Technologies SymphonyX solid phase peptide synthesizer, using the manufacturer supplied protocols with minor modifications. Mixing was accomplished by occasional bubbling with nitrogen. The step-wise assembly was performed using the following steps: 1) pre-swelling of resin in DMF; 2) Fmoc-deprotection by the use of 20% (v/v) piperidine in DMF for two treatments of 10 min each; 3) washes with DMF to remove piperidine; 4) coupling of Fmoc-amino acid by the addition of Fmoc-amino acid (12 equiv) and Oxyma Pure® (12 equiv) as a 0.6 M solution each in DMF, followed by addition of DIC (12 equiv) as a 1.2 M solution in DMF, followed by the addition of DMF to reduce the final concentration of each component to 0.3 M, then mixing for 0.5-4 h; 4) washes with DMF to remove excess reagents; 5) final washes with DCM at the completion of the assembly. Some amino acids such as, but not limited to, those following a sterically hindered amino acid (e.g. Aib) were coupled with an extended reaction time (e.g. 4 h) to ensure reaction completion.
  • Method: SPPS_B
  • The protected peptidyl resin was synthesized according to the Fmoc strategy on an Applied Biosystems 431A solid-phase peptide synthesizer using the manufacturer supplied general Fmoc protocols. Mixing was accomplished by vortexing and occasional bubbling with nitrogen. The step-wise assembly was done using the following steps: 1) activation of Fmoc-amino acid by dissolution of solid Fmoc-acid acid (10 equiv) in CI-HOBt (10 equiv) as a 1 M solution in NMP, then addition of DIC (10 equiv) as a 1 M solution in NMP, then mixing simultaneous to steps 2-3; 2) Fmoc-deprotection by the use of 20% (v/v) piperidine in NMP for one treatment of 3 min then a second treatment of 15 min; 3) washes with NMP to remove piperidine; 4) addition of activated Fmoc-amino acid solution to resin, then mixing for 45-90 min; 4) washes with NMP to remove excess reagents; 5) final washes with DCM at the completion of the assembly. The standard protected amino acid derivatives listed above were supplied in pre-weighed cartridges (from e.g. Midwest Biotech), and non-standard derivatives were weighed by hand. Some amino acids such as, but not limited to, those following a sterically hindered amino acid (e.g. Aib) were “double coupled” to ensure reaction completion, meaning that after the first coupling (e.g. 45 min) the resin is drained, more reagents are added (Fmoc-amino acid, DIC, CI-HOBt), and the mixture allowed to react again (e.g. 45 min).
  • Method: SPPS_C
  • SPPS was performed using Fmoc based chemistry on a PreludeX solid phase peptide synthesizer, using the manufacturer supplied protocols with minor modifications. Mixing was accomplished by shaking at 350 rpm and occasional bubbling with nitrogen. The step-wise assembly was performed using the following steps: 1) pre-swelling of resin in DMF; 2) Fmoc-deprotection by the use of 20% (v/v) piperidine in DMF for one treatment of 3 min at 70° C.; 3) washes with DMF to remove piperidine; 4) coupling of Fmoc-amino acid by the addition of Fmoc-amino acid (12 equiv) and Oxyma Pure® (12 equiv) as a 0.4 M solution each in DMF, followed by addition of DIC (12 equiv) as a 1.2 M solution in DMF, then mixing for 5 min at 70° C.; 4) washes with DMF to remove excess reagents; 5) final washes with DCM at the completion of the assembly. Some amino acids such as, but not limited to, those following a sterically hindered amino acid (e.g. Aib) were coupled with an extended reaction time (e.g. 15 min) to ensure reaction completion.
  • 2. Attachment of Substituent to Resin-Bound Protected Peptide Backbone
  • Method: SC_A
  • The N-epsilon-lysine protection Mtt protection group was removed by washing the resin with 30% HFIP in DCM for two treatments of 45 min each, following by washing with DCM and DMF. Acylation was performed on a Protein Technologies SymphonyX solid phase peptide synthesizer using the protocols described in method SPPS_A using stepwise addition of building blocks, such as, but not limited to, Boc-Lys(Fmoc)-OH, Fmoc-8-amino-3,6-dioxaoctanoic acid, Fmoc-Glu-OtBu, hexadecanedioic acid mono-tert-butyl ester, octadecanedioic acid mono-tert-butyl ester, and eicosanedioic acid mono-tert-butyl ester.
  • Method: SC_B
  • The N-epsilon-lysine protection Mtt protection group was removed by washing the resin with 30% HFIP in DCM for two treatments of 45 min each, following by washing with DCM and DMF. Acylation was performed on an Applied Biosystems 431A solid-phase peptide synthesizer using the protocols described in method SPPS_B using stepwise addition of building blocks, such as, but not limited to, Boc-Lys(Fmoc)-OH, Fmoc-8-amino-3,6-dioxaoctanoic acid, Fmoc-Glu-OtBu, hexadecanedioic acid mono-tert-butyl ester, octadecanedioic acid mono-tert-butyl ester, and eicosanedioic acid mono-tert-butyl ester.
  • Method: SC_C
  • The N-epsilon-lysine protection Mtt protection group was removed by washing the resin with 30% HFIP in DCM for two treatments of 45 min each, following by washing with DCM and DMF. Acylation was performed on a Protein Technologies PreludeX solid phase peptide synthesizer using the protocols described in method SPPS_C using stepwise addition of building blocks, such as, but are not limited to, Boc-Lys(Fmoc)-OH, Fmoc-8-amino-3,6-dioxaoctanoic acid, Fmoc-Glu-OtBu, hexadecanedioic acid mono-tert-butyl ester, octadecanedioic acid mono-tert-butyl ester, and eicosanedioic acid mono-tert-butyl ester.
  • 3. Cleavage of Resin Bound Peptide and Purification:
  • Method: CP_A
  • Following completion of the sidechain synthesis, the peptidyl resin was washed with DCM and dried, then treated with TFA/water/TIS (95:2.5:2.5 v/v/v) for approximately 2 h, followed by precipitation with diethyl ether. The precipitate was washed with diethyl ether, dissolved in a suitable solvent (e.g. 2:1 water/MeCN), and let stand until all labile adducts decomposed. Purification was performed by reversed-phase preparative HPLC (Waters 2545 binary gradient module, Waters 2489 UV/Visible detector, Waters fraction collector III) on a Phenomenex Luna C8(2) column (10 μM particle size, 100 Å pore size, 250×21.2 mm dimensions). Separation of impurities and product elution was accomplished using an increasing gradient of MeCN in water containing 0.1% TFA. Relevant fractions were checked for identity and purity by analytical LCMS. Fractions containing the pure desired product were pooled and freeze-dried to afford the peptide TFA salt as a white solid.
  • 4. Salt Exchange from TFA to Sodium Salt:
  • Method: SX_A
  • The freeze-dried peptide isolated from method CP_A was dissolved to 5-20 mg/mL in an appropriate aqueous buffer (e.g. 4:1 water/MeCN, 0.2 M sodium acetate) and adjusted to pH 7-8 with 1 M NaOH if necessary to achieve full solubility. The buffered solutions containing the peptide were salt-exchanged using a Sep-Pak C18 cartridge (0.5-2 g): The cartridge was first equilibrated with 4 column volumes of isopropanol, then 4 column volumes of MeCN, then 8 column volumes of water. The peptide solution was applied to the cartridge, and the flow through was reapplied to ensure complete retention of peptide. The cartridge was washed with 4 column volumes of water, then 10 column volumes of a buffer solution (e.g. pH 7.5) containing such as, but not limited to, NaHCO3, NaOAc, or Na2HPO4. The column was washed with 4 column volumes of water, and the peptide was eluted with 5-10 column volumes of 50-80% MeCN in water. The peptide-containing eluent was freeze-dried to afford the peptide sodium salt as a white solid, which was used as such.

    • Example 2: In Vitro Functional Potency (CRE Luciferase; Whole Cells)
  • The purpose of this example is to test the functional activity, or potency, of the compounds in vitro at the human GLP-1 and GIP receptors. The in vitro functional potency is the measure of target receptor activation in a whole cell assay. The potencies of derivatives of Example 1 were determined as described below. Human GLP-1(7-37) and human GIP were included in appropriate assays for comparison.
    • Principle
  • In vitro functional potency was determined by measuring the response of the target receptor in a reporter gene assay in individual cell lines. The assay was performed in stably transfected BHK cell lines that expresses one of the following G-protein coupled receptors: human GLP-1 receptor or human GIP receptor; and where each cell line contains the DNA for the cAMP response element (CRE) coupled to a promoter and the gene for firefly luciferase (CRE luciferase). When the respective receptor is activated, it results in the production of cAMP, which in turn results in expression of the luciferase protein. When assay incubation is completed, luciferase substrate (luciferin) is added resulting in the enzymatic conversion of luciferin to oxyluciferin and producing bioluminescence. The luminescence is measured as the readout for the assay.
    • Cell Culture and Preparation
  • The cells lines used in these assays were BHK cells with BHKTS13 as a parent cell line. The cell lines were derived from a clone containing the CRE luciferase element and were established by further transfection with the respective human receptor to obtain the relevant cell line: BHK CRE luc2P hGLP-1R or BHK CRE luc2P hGIPR. The cells were cultured at 37° C. with 5% CO2 in Cell Culture Medium. They were aliquoted and stored in liquid nitrogen. The cells were kept in continuous culture and were seeded out the day before each assay.
    • Materials
  • The following chemicals were used in the assay: Pluronic F-68 10% (Gibco 2404), human serum albumin (HSA; Sigma A9511), 10% fetal bovine serum (FBS; Invitrogen 16140-071), chicken egg white ovalbumin (Sigma A5503), DMEM w/o phenol red (Gibco 21063-029), DMEM (Gibco 12430-054), 1 M Hepes (Gibco 15630), Glutamax 100× (Gibco 35050), G418 (Invitrogen 10131-027), hygromycin (Invitrogen 10687-010), and steadylite plus (PerkinElmer 6016757).
    • Buffers
  • GLP-1R Cell Culture Medium consisted of DMEM medium with 10% FBS, 500 μg/mL G418, and 300 μg/mL hygromycin. GIPR Cell Culture Medium consisted of DMEM medium with 10% FBS, 400 μg/mL G418, and 300 μg/mL hygromycin. Assay Buffer consisted of DMEM w/o phenol red, 10 mM Hepes, 1× Glutamax. 1% ovalbumin, and 0.1% Pluronic F-68 with the addition of HSA at twice the final assay concentration. The Assay Buffer was mixed 1:1 with an equal volume of the test compound in Assay Buffer to give the final assay concentration of HSA.
  • Procedure
      • 1) Cells were plated at 5000 cells/well and incubated overnight in the assay plate.
      • 2) Cells were washed once in DPBS.
      • 3) Stocks of the test compounds and reference compounds in concentrations ranging from 100-300 pM were diluted 1:150 in Assay Buffer. Compounds were then diluted 1:10 in column 1 of a 96 deep well dilution plate and then carried across the row creating a 3.5 fold, 12 point dilution curve.
      • 4) Assay Buffer (50 μl aliquot) with or without HSA was added to each well in the assay plate.
      • 5) A 50 μl aliquot of compound or blank was transferred from the dilution plate to the assay plate containing the Assay Buffer with or without HSA.
      • 6) The assay plate was incubated for 3 h in a 5% CO2 incubator at 37° C.
      • 7) The cells were washed once with DPBS.
      • 8) A 100 μl aliquot of DPBS was added to each well of the assay plate.
      • 9) A 100 μl aliquot of steadylite plus reagent (light sensitive) was added to each well of the assay plate.
      • 10) Each assay plate was covered with aluminum foil to protect it from light and shaken at 250 RPM for 30 min at room temperature.
      • 11) Each assay plate was read in a microtiter plate reader.
    Calculations and Results
  • The data from the microtiter plate reader was first regressed in an Excel in order to calculate the x-axis, log scale concentrations based on the individual test compound's stock concentration and the dilutions of the assay. This data was then transferred to GraphPad Prism software for graphing and statistical analysis. The software performs a non-linear regression (log(agonist) vs response). EC50 values which were calculated by the software and reported in pM are shown in Tables 1-3 below. A minimum of two replicates was measured for each sample. The reported values are averages of the replicates.

  • The compounds of the present invention display potent functional activation of the human GLP-1R and human GIPR receptors under the given conditions. Alteration of the peptide and/or the substituent resulted in unpredictable changes in the measured potencies at each of the two receptors, as well as the ratio of potencies between the two receptors, for each compound.
    • Example 3: Pharmacokinetic Study in Minipigs
  • The purpose of this example is to determine the half-life in vivo of the derivatives of the present invention after i.v. administration to minipigs, i.e. the prolongation of their time in the body and thereby their time of action. This is done in a pharmacokinetic (PK) study, where the terminal half-life of the derivative in question is determined. By terminal half-life is generally meant the period of time it takes to halve a certain plasma concentration, measured after the initial distribution phase.
    • Study
  • Female Gottingen minipigs were obtained from Ellegaard Gottingen Minipigs (Dalmose, Denmark) approximately 7-14 months of age and weighing from approximately 16-35 kg were used in the studies. The minipigs were housed individually and fed restrictedly once daily with SDS minipig diet (Special Diets Services, Essex, UK).
  • After at 3 weeks of acclimatisation two permanent central venous catheters were implanted in vena cava caudalis in each animal. The animals were allowed 1 week recovery after the surgery, and were then used for repeated pharmacokinetic studies with a suitable wash-out period between successive derivative dosing.
  • The animals were fasted for approximately 18 hours before dosing and from 0 to 4 hours after dosing but had ad libitum access to water during the whole period.
  • The sodium salts of compounds of Examples 1 were dissolved to a concentration of 20-40 nmol/mL in a buffer containing 0.007% polysorbate 20, 50 mM sodium phosphate, 70 mM sodium chloride, pH 7.4. Intravenous injections (the volume corresponding to usually 1.5-2 nmol/kg, for example 0.1 mL/kg) of the compounds were given through one catheter, and blood was sampled at predefined time points for up to 14 days post dosing (preferably through the other catheter). Blood samples (for example 0.8 mL) were collected in 8 mM EDTA buffer and then centrifuged at 4° C. and 1942 g for 10 minutes.
    • Sampling and Analysis
  • Plasma was pipetted into Micronic tubes on dry ice and kept at −20° C. until analysed for plasma concentration of the compounds using ELISA, or a similar antibody-based assay, or LCMS. Individual plasma concentration-time profiles were analysed by a non-compartmental model in Phoenix WinNonLin ver. 6.4. (Pharsight Inc., Mountain View, Calif., USA), and the resulting terminal half-lives (harmonic mean) determined.

  • The tested compounds of the present invention have very long half-lives as compared to the half-lives of hGLP-1 and hGIP measured in man to be approximately 2-4 min and 5-7 min, respectively (Meier et al., Diabetes, 2004, 53(3): 654-662). The measured half-lives in minipigs predict half-lives in humans sufficient for at least once-weekly administration via liquid injection or at least once-daily administration via oral tablet. Unexpectedly, alterations to the peptide sequence led to appreciable differences in half-lives between co-agonists tested herein even though these co-agonists incorporate the same substituent.
    • Example 5: Pharmacokinetic Study in Dogs
  • The purpose of this example is to determine the half-life and plasma exposure in vivo of the compounds of the present invention after p.o. administration to beagle dogs, i.e. the terminal half-life and concentration of test substance that reaches circulation with time. This is done in a pharmacokinetic (PK) study, where these parameters of the compound in question are determined. By terminal half-life is generally meant the period of time it takes to halve a certain plasma concentration, measured after the initial distribution phase.
  • Preparation of Tablet Compositions
  • Tablet compositions comprising the test substance and SNAC (sodium N-(8-(2-hydroxybenzoyl)amino)caprylate) were prepared according to methods known to the person skilled in the art by mixing test substance with roller compacted SNAC and magnesium stearate as e.g. described in WO 2019/149880. The amount of SNAC in the tablet composition was 100-300 mg, the amount of magnesium stearate in the tablet composition was 7.7 mg, and the target amount of each test substance in the tablet composition was 3-4 mg.
  • Animals, Dosing, and Sampling
  • Male beagle dogs, 1-7 years of age and weighing 9-17 kg during the study period, were included in the study. The dogs were dosed in a fasting state. The dogs were group housed in pens (12 hours light: 12 hours dark), and fed individually and restrictedly once daily with Royal Canin Medium Adult dog food (Royal Canin Products, China Branch, or Brogaarden A/S, Denmark). The dogs were used for repeated PK studies with a suitable wash-out period between successive dosing. An appropriate acclimatization period was given prior to initiation of the first PK study. All handling, dosing, and blood sampling of the animals were performed by trained and skilled staff. Before the studies, the dogs were fasted overnight and from 0 to 4 hours after dosing. The dogs were restricted to water 1 hour before dosing until 4 hours after dosing, but otherwise had ad libitum access to water during the whole period.
  • The compositions were administered by a single oral dosing to the dogs in groups of 6-8 dogs. The tablets were administered in the following manner: 10 min prior to tablet administration, the dogs may be dosed subcutaneously with approximately 3 nmol/kg of SEQ ID NO: 48, then tablets were placed in the back of the mouth of the dog to prevent chewing. The mouth was then closed, and 10 mL of tap water was given by syringe or gavage to facilitate swallowing of the tablet.
  • One blood sample was drawn before dosing, and additional samples were drawn at predefined time points after dosing for up to 240 hours, such as up to 10 hours, to adequately cover the full plasma concentration-time absorption profile of the test substance. For each blood sample time point, approximately 0.8 mL of whole blood was collected in a 1.5 mL EDTA-coated tube, which was gently turned to mix the sample with EDTA. Blood samples were collected in EDTA buffer (8 mM) and then centrifuged at 4° C. 2000 g for 10 minutes. Plasma was pipetted into Micronic tubes on dry ice, and kept at −20° C. or lower until analysis. Blood samples were taken as appropriate, for example from a venflon in the cephalic vein in the front leg for the first 2 hours and then with syringe from the jugular vein for the rest of the time points. The first few drops were allowed to drain from the venflon to avoid heparin saline from the venflon in the sample.
  • All blood samples were collected into test tubes containing EDTA for stabilisation and kept on ice until centrifugation. Plasma was separated from whole blood by centrifugation and the plasma was stored at −20° C. or lower until analysis.
  • Analysis and Calculations
  • The plasma was analysed for test substance using LC-MS (Liquid Chromatography-Mass Spectrometry) as known to the person skilled in the art. The system consisted of either: a Thermo Fisher QExactive mass spectrometer equipped with a 10-valve interface module TurboFlow system, CTC HTS PAL autosampler, Accela 1250 pumps, and Hot Pocket column oven; or a Thermo Fisher QExactive Plus mass spectrometer equipped with a valve interface module TurboFlow system, TriPlus RSI autosampler, Dionex UltiMate 3000 pumps, and Hot Pocket column oven. RP-HPLC separation was achieved using a linear gradient of 1:1 acetonitrile/methanol in 1% aqueous formic acid using either: a Phenomenex Onyx Monolithic C18 column (50×2.0 mm) and a flow rate of 0.8 mL/min at 30° C.; or an Agilent Poroshell 120 SB-C18 column (50×2.1 mm, 2.7 μm) at a flow rate of 0.4 mL/min at 60° C. The mass spectrometer was operated in either positive ionization SIM mode or positive ionization PRM mode.
  • For each individual animal, a plasma concentration-time profile was analysed by a non-compartmental model in Pharsight Phoenix WinNonLin ver. 6.4 software or other relevant software for PK analysis, and the resulting terminal half-life (t1/2), maximum plasma concentration per dose (Cmax/D), time for maximum plasma concentration (tmax), and area under the curve to infinity per dose (AUC/D) were determined. Summary statistics of pharmacokinetic results were presented as median (for tmax), hormonic mean (t1/2), or arithmetic mean (Cmax, AUC).

  • The tested compounds of the present invention demonstrate oral bioavailability in this model, as concentrations of the compound in plasma were detected (Cmax/D>0 and AUC/D>0) following oral administration. Furthermore, the tested compounds of the present invention further have very long half-lives as compared to the half-lives of hGLP-1 and hGIP measured in man to be approximately 2-4 min and 5-7 min, respectively (Meier et al., Diabetes, 2004, 53(3): 654-662). Alterations to the peptide sequence led to unpredictable differences in t1/2, Cmax/D and AUC/D between co-agonists even when the same substituent was incorporated. Additionally, an unexpectedly large difference in t1/2 was observed depending on the position of the amino acid attached to the substituent, such as eg., Compound No. 43 compared to all other compounds tested herein.
  • While certain features of the invention have been illustrated and described herein, many modifications, substitutions, changes, and equivalents will now occur to those of ordinary skill in the art. It is, therefore, to be understood that the appended embodiments are intended to cover all such modifications and changes as fall within the true spirit of the invention.
