TITLE IMPROVED GIP RECEPTOR AGONIST PEPTIDE COMPOUNDS AND USES THEREOF PRIORITY CLAIM
[0001] This application claims priority to U.S. Provisional Patent Application No.63 / 622,637,filed January 19, 2024, which is incorporated by reference in its entirety. TECHNICAL FIELD
[0002] The present disclosure relates to a novel improved peptide compound having an agonistaction on GIP receptors and use of the peptide compound as a medicament which may be dosed in a once weekly dosing regimen to prevent or treat emesis, and the symptoms of emesis, for example, nausea and / or vomiting. REFERENCE TO THE SEQUENCE LISTING
[0003] This application contains a Sequence Listing which has been submitted electronically inXML format and which is hereby incorporated by reference in its entirety. The XML copy, created on January 17, 2025, is named “223266-538623_Sequence-Listing.xml” and is 66 kilobytes in size. 59057274.1BACKGROUND
[0004] The statements in this section merely provide background information related to thepresent disclosure and may not constitute prior art.
[0005] Both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropicpolypeptide (GIP) are peptides called incretins. GLP-1 and GIP are secreted from small intestinal L cells and K cells, respectively.
[0006] GLP-1 acts via GLP-1 receptors and is known to have a glucose-dependentinsulinotropic action and a feeding suppressive action. On the other hand, GIP is known to have a glucose-dependent insulinotropic action via the GIP receptors (GIPr), although the effect of GIP alone on feeding (e.g., feeding suppression) is being determined.
[0007] Attempts have been made to search for peptides having GLP-1 receptor / GIP receptorcoagonist or glucagon receptor / GLP-1 receptor / GIP receptor triagonist activity and modifications thereof and develop these peptides as anti-obesity drugs, therapeutic drugs for metabolic diseases (e.g., diabetes, obesity), or therapeutic drugs for other disorders based on the structure of natural glucagon, GIP, or GLP-1. There is a need for novel peptide compounds having a selective activating action on GIP receptors of the present disclosure for the use in treating or preventing emesis and similar symptoms associated with nausea and vomiting. 59057274.1
[0008] Patients who experience nausea and vomiting are often unwilling or unable to take theirmedications regularly; several studies have shown that less frequent dosing results in higher degree of compliance and thus eventually better treatment of the patients. Therefore, there is an unmet need for longer acting preparations of antiemetic medicine. In particular there is a need for longer acting preparations of antiemetic GIP receptor agonist peptides that represent an alternative to twice per day (BID) dosing formulations in order to make a change in dosing regimen, frequency of medication or type of medication, more flexible. Extending the duration of action will also provide a benefit in diseases where the duration of emetic episodes is longer. SUMMARY
[0009] A GIP receptor agonist peptide compound can have a GIP receptor agonism action andcan be useful as a preventive / therapeutic agent for diabetes, obesity, and / or an antiemetic agent to prevent / treat diseases accompanied by vomiting or nausea.
[0010] The present disclosure provides GIPr agonist peptide compounds including a sequencerepresented by Formulae (I), (I-A) and / or (I-B). The GIPr agonist peptide compounds are useful as therapeutic agents for the prevention or treatment of emesis as described herein. Surprisingly, the compounds of Formulae (I), (I-A) and / or (I-B) exhibit excellent GIP receptor activation action, a longer ½ life of elimination and improved solubility (e.g., as compared to that of the native ligand, 59057274.1human native GIP peptide). In some instances, the peptides of Formulae (I), (I-A) and / or (I-B) relative to other known GIPr agonist peptides in the art possess improved properties in one or more of: (1) stability in serum; (2) half-life of elimination; and (3) solubility. In certain embodiments of this disclosure, the peptides of Formulae (I), (I-A) and / or (I-B) relative to other known GIPr agonist peptides that are dosed once per day to treat emesis, or which may be useful as preventative agents of nausea and / or vomiting and other symptoms of emesis, demonstrate an improved profile.

[0143] It should be understood that this disclosure is not limited to the particular methodology,protocols, and reagents, etc., described herein and as such can vary. The terminology used herein is for the purpose of describing particular embodiments only, and is not intended to limit the scope of the present disclosure, which is defined solely by the claims. Other features and advantages of 59057274.1the disclosure will be apparent from the following Detailed Description, the drawings, and the claims. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0144] The present disclosure provides a novel class of selective GIP receptor agonists. TheGIP receptor agonist peptide discussed herein can be used in the preparation of a composition or method for the prevention and / or treatment of a medical condition, or disorder, dosed subcutaneously once weekly (QW) for the rescue (e.g., on-demand rescue) and / or maintenance of nausea and vomiting, for example, treating Cyclic Vomiting Syndrome (CVS). The GIP receptor agonist peptide can be administered by any suitable means including parenteral, e.g., subcutaneous injection, intravenously, by inhalation (e.g., nasal spray), topically, or by oral delivery.
[0145] Most G protein-coupled receptors (GPCRs) undergo some degree of internalizationfollowing agonist binding. Internalization can play a role in downregulation of the GPCRs’ ability to signal at the membrane. Additionally, internalized GPCRs can engage novel signaling pathways inaccessible to GPCRs residing on the surface membrane. Thus, internalization of a GPCR in response to a ligand can be considered a form of signaling. GIP receptors exhibit variable internalization in response to an agonist, with some agonists promoting marked internalization and 59057274.1others being inactive.
[0146] It is believed that GIP receptors may also recruit arrestin to the plasma membrane. β-arrestins are multifunctional proteins that downregulate G protein signaling through direct interactions with GPCRs, as well as serving as scaffolds to recruit other signaling complexes to GPCRs.
[0147] The GIPr agonist peptides of Formulae (I), (I-A) and / or (I-B) as disclosed herein, andpharmaceutically acceptable salts thereof, show an improved profile in subjects dosed with the GIPr agonist. A dose can be a physiologically active or pharmacologically active dose. A physiologically active dose is a dose that is characteristic of or appropriate to the healthy or normal functioning of an organism (e.g., a subject, for example, a human). A pharmacologically active dose is a dose that provides an effect (beneficial or adverse) (e.g., beneficial effect) of a drug on living matter (e.g., a subject, for example, a human). In certain embodiments, a GIP receptor agonist peptide or pharmaceutically acceptable salt thereof, is dosed at physiologically active and pharmacologically active doses, (for example, 0.01 to 0.5 mg / kg / day, 0.1 to 5 mg / kg / day, 5 to 10 mg / kg / day (e.g., up to 5mg / kg / day or 1000nmol / kg), 10 to 20 mg / kg / day, 20 to 50 mg / kg / day, 10 to 100 mg / kg / day, 10 to 120 mg / kg / day, 50 to 100 mg / kg / day, 100 to 200 mg / kg / day, 200 to 300 mg / kg / day, 300 to 400 mg / kg / day, 400 to 500 mg / kg / day, 500 to 600 mg / kg / day, 600 to 700 59057274.1mg / kg / day, 700 to 800 mg / kg / day, 800 to 900 mg / kg / day, or 900 to 1000 mg / kg / day), or the human equivalent dose. The methods of the present disclosure permit administration of the GIP receptor agonist peptide or medicament to a subject in need thereof, for 1-5 days, 1-5 weeks, 1-5 months, or 1-5 years, and any time periods there between.

[0309] PEG is available in a variety of molecular weights based on the number of repeatingsubunits of ethylene oxide (i.e. —OCH2CH2—) within the molecule.PEG formulations are usually followed by a number that corresponds to their average molecular weight. For example, PEG-200 has a weight average molecular weight of 200 Daltons and may have a molecular weight range of 190-210 Daltons. Molecular weight in the context of a water-soluble polymer, such as PEG, can be expressed as either a number average molecular weight or a weight average molecular weight. Unless otherwise indicated, all references to molecular weight of PEG herein refer to the weight average molecular weight. Both molecular weight determinations, number average and weight average, can be measured using gel permeation chromatography or other liquid chromatography techniques. Other methods for measuring molecular weight values can also be used, such as the use of end-group analysis or the measurement of colligative properties (e.g., freezing-point 59057274.1depression, boiling-point elevation, or osmotic pressure) to determine number average molecular weight or the use of light scattering techniques, ultracentrifugation or viscometry to determine weight average molecular weight.
[0310] As used herein, "PEG moiety" refers to polyethylene glycol (PEG) or a derivativethereof, for example (methoxy)polyethylene glycol (mPEG).
[0311] As used herein, "PEGylated peptide" refers to a peptide wherein at least one amino acidresidue, for example, Lys, or Cys has been conjugated with a PEG moiety. By "conjugated", it is meant that the PEG moiety is either directly linked to said residue or is linked to the residue via a spacer moiety, for example a cross-linking agent. When said conjugation is at a lysine residue, that lysine residue is referred to herein as "PEGylated Lys". A peptide that is conjugated to only one PEG moiety is said to be "mono-PEGylated".
[0312] As used herein, "Lys-PEG" and "Lys-PEGm" refer respectively to lysine residues whichhave been conjugated with PEG. "Lys(epsilon-SSA-PEGn)" refers to a lysine residue wherein the epsilon-amino group has been cross-linked with MPEG using a suitably functionalized SSA.
[0313] In the present specification, the term “human native GIP peptide” refers to the naturallyoccurring human GIP peptide. This human native GIP peptide (42 amino acids) has an amino acid sequence: YAEGTFISDYSIAMDKIHQQDFVNWLLAQKGKKNDWKHNITQ (SEQ ID NO: 1) 59057274.1and is the functionally active molecule derived from the parent precursor described in National Center for Biotechnology Information (NCBI) Reference Sequence: NP_004114.1; REFSEQ: accession NM_004123.2 This full length precursor is encoded from the mRNA sequence of human gastric inhibitory polypeptide (GIP), mRNA; ACCESSION: NM_004123; VERSION; NM_004123.2.
[0314] "Percent (%) amino acid sequence identity" with respect to a reference polypeptidesequence is defined as the percentage of amino acid residues in a candidate polypeptide sequence that are identical with the amino acid residues in the reference polypeptide sequence, after aligning the sequences and introducing gaps, if necessary, to achieve the maximum percent sequence identity, and not considering any conservative substitutions as part of the sequence identity. Alignment for purposes of determining percent amino acid sequence identity can be achieved in various ways that are within the skill in the art, for instance, using publicly available computer software such as BLAST, BLAST-2, ALIGN or Megalign (DNASTAR) software. Those skilled in the art can determine appropriate parameters for aligning sequences, including any algorithms needed to achieve maximal alignment over the full length of the sequences being compared.
[0315] As used herein, "treatment" (and variations such as "treat" or "treating") refers toclinical intervention in an attempt to alter the natural course of the individual being treated, and 59057274.1can be performed either for prophylaxis or during the course of clinical pathology. Desirable effects of treatment include, but are not limited to, preventing occurrence or recurrence of a condition, alleviation of symptoms, diminishment of any direct or indirect pathological consequences of the condition or treatment, preventing emesis, i.e., by preventing the occurrence of symptoms in whole or in part associated with a condition or side-effects known to accompany a specific treatment, decreasing the rate of progression, amelioration or palliation of the symptoms associated with emesis, such as nausea and / or vomiting, and remission or improved prognosis. In some embodiments, GIP receptor agonist peptides of the disclosure are used to inhibit or delay development of emesis, i.e. nausea or vomiting or to slow the progression of emesis or the symptoms associated with emesis, or to prevent, delay or inhibit the development of emesis, nausea and / or vomiting related to the treatment of a different disease being actively treated.
[0316] By "reduce" or "inhibit" is meant the ability to cause an overall decrease of 20%, 30%,40%, 50%, 60%, 70%, 75%, 80%, 85%, 90%, 95%, or greater. In some embodiments, reduce or inhibit can refer to a relative reduction compared to a reference (e.g., reference level of biological activity (e.g., the number of episodes of nausea and / or vomiting after administration to a subject of a prescribed amount of chemotherapy, for example, a prescribed dose of a chemotherapeutic agent that is known to cause emesis). In some embodiments, reduce or inhibit can refer to the 59057274.1relative reduction of a side effect (i.e. nausea and / or vomiting) associated with a treatment for a condition or disease.
[0317] Optimal alignment of sequences for comparison can be conducted, for example, by thelocal homology algorithm of Smith and Waterman (Adv. Appl. Math. 2:482 (1981), which is incorporated by reference herein), by the homology alignment algorithm of Needleman and Wunsch (J. MoI. Biol.48:443-53 (1970), which is incorporated by reference herein), by the search for similarity method of Pearson and Lipman (Proc. Natl. Acad. Sci. USA 85:2444-48 (1988), which is incorporated by reference herein), by computerized implementations of these algorithms (e.g., GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.), or by visual inspection. (See generally Ausubel et al. (eds.), Current Protocols in Molecular Biology, 4th ed., John Wiley and Sons, New York (1999)).
[0318] One illustrative example of an algorithm that is suitable for determining percentsequence identity and sequence similarity is the BLAST algorithm, which is described by Altschul et al. (J. MoI. Biol. 215:403-410 (1990), which is incorporated by reference herein). (See also Zhang et al., Nucleic Acid Res. 26:3986-90 (1998); Altschul et al., Nucleic Acid Res. 25:3389- 402 (1997), which are incorporated by reference herein). Software for performing BLAST 59057274.1analyses is publicly available through the National Center for Biotechnology Information internet web site. This algorithm involves first identifying high scoring sequence pairs (HSPs) by identifying short words of length W in the query sequence, which either match or satisfy some positive-valued threshold score T when aligned with a word of the same length in a database sequence. T is referred to as the neighborhood word score threshold (Altschul et al. (1990), supra). These initial neighborhood word hits act as seeds for initiating searches to find longer HSPs containing them. The word hits are then extended in both directions along each sequence for as far as the cumulative alignment score can be increased. Extension of the word hits in each direction is halted when: the cumulative alignment score falls off by the quantity X from its maximum achieved value; the cumulative score goes to zero or below, due to the accumulation of one or more negative-scoring residue alignments; or the end of either sequence is reached. The BLAST algorithm parameters W, T, and X determine the sensitivity and speed of the alignment. The BLAST program uses as defaults a word length (W) of 11, the BLOSUM62 scoring matrix (see Henikoff and Henikoff, Proc. Natl. Acad. Sci. USA 89:10915-9 (1992), which is incorporated by reference herein) alignments (B) of 50, expectation (E) of 10, M=5, N=-4, and a comparison of both strands. 59057274.1
[0319] In addition to calculating percent sequence identity, the BLAST algorithm alsoperforms a statistical analysis of the similarity between two sequences (see, e.g., Karlin and Altschul, Proc. Natl. Acad. Sci. USA 90:5873-77 (1993), which is incorporated by reference herein). One measure of similarity provided by the BLAST algorithm is the smallest sum probability (P(N)), which provides an indication of the probability by which a match between two nucleotide or amino acid sequences would occur by chance. For example, an amino acid sequence is considered similar to a reference amino acid sequence if the smallest sum probability in a comparison of the test amino acid to the reference amino acid is less than about 0.1, more typically less than about 0.01, and most typically less than about 0.001.
[0320] Variants can also be synthetic, recombinant, or chemically modified polynucleotidesor polypeptides isolated or generated using methods well known in the art. Variants can include conservative or non-conservative amino acid changes, as described below. Polynucleotide changes can result in amino acid substitutions, additions, deletions, fusions and truncations in the polypeptide encoded by the reference sequence. Variants can also include insertions, deletions or substitutions of amino acids, including insertions and substitutions of amino acids and other molecules) that do not normally occur in the peptide sequence that is the basis of the variant, for example but not limited to insertion of ornithine which do not normally occur in human proteins. 59057274.1The term "conservative substitution," when describing a polypeptide, refers to a change in the amino acid composition of the polypeptide that does not substantially alter the polypeptide's activity. For example, a conservative substitution refers to substituting an amino acid residue for a different amino acid residue that has similar chemical properties. Conservative amino acid substitutions include replacement of a leucine with an isoleucine or valine, an aspartate with a glutamate, or a threonine with a serine.
[0321] "Conservative amino acid substitutions" as referenced herein result from replacing oneamino acid with another having similar structural and / or chemical properties, such as the replacement of a leucine with an isoleucine or valine, an aspartate with a glutamate, or a threonine with a serine. Thus, a "conservative substitution" of a particular amino acid sequence refers to substitution of those amino acids that are not critical for polypeptide activity or substitution of amino acids with other amino acids having similar properties (e.g., acidic, basic, positively or negatively charged, polar or non-polar, etc.) such that the substitution of even critical amino acids does not reduce the activity of the peptide, (i.e. the ability of the peptide to penetrate the blood brain barrier (BBB)). Conservative substitution tables providing functionally similar amino acids are well known in the art. For example, the following six groups each contain amino acids that are conservative substitutions for one another: 1) Alanine (A), Serine (S), Threonine (T); 2) Aspartic 59057274.1acid (D), Glutamic acid (E); 3) Asparagine (N), Glutamine (Q); 4) Arginine (R), Lysine (K); 5) Isoleucine (I), Leucine (L), Methionine (M), Valine (V); and 6) Phenylalanine (F), Tyrosine (Y), Tryptophan (W). (See also Creighton, Proteins, W. H. Freeman and Company (1984), incorporated by reference in its entirety.) In some embodiments, individual substitutions, deletions or additions that alter, add or delete a single amino acid or a small percentage of amino acids can also be considered "conservative substitutions" if the change does not reduce the activity of the peptide. Insertions or deletions are typically in the range of about 1 to 5 amino acids. The choice of conservative amino acids may be selected based on the location of the amino acid to be substituted in the peptide, for example if the amino acid is on the exterior of the peptide and expose to solvents, or on the interior and not exposed to solvents.
[0322] In alternative embodiments, one can also select conservative amino acid substitutionsencompassed suitable for amino acids on the interior of a protein or peptide, for example one can use suitable conservative substitutions for amino acids is on the interior of a protein or peptide (i.e., the amino acids are not exposed to a solvent), for example but not limited to, one can use the following conservative substitutions: where Y is substituted with F, T with A or S, I with L or V, W with Y, M with L, N with D, G with A, T with A or S, D with N, I with L or V, F with Y or L, 59057274.1S with A or T and A with S, G, T or V. In some embodiments, non-conservative amino acid substitutions are also encompassed within the term of variants.
[0323] As used herein, the term "selectivity" of a molecule for a first receptor relative to asecond receptor refers to the following ratio: EC50of the molecule at the second receptor divided by the EC50 of the molecule at the first receptor. For example, a molecule that has an EC50 of 1 nM at a first receptor and an EC50 of 100 nM at a second receptor has 100-fold selectivity for the first receptor relative to the second receptor. EC50 is the concentration required to obtain 50% of an effect or response.
[0324] As is understood by one skilled in the art, reference to "about" a value or parameterherein includes (and describes) embodiments that are directed to that value or parameter per se or that have a variance plus or minus of that value ranging from less than 10%, or less than 9%, or less than 8%, or less 7%, or less than 6%, or less than 5%, or less than 4%, or less than 3%, or less than 2%, or less than 1%, or less than 0.1 % than the stated value. For example, description referring to "about X" includes description of "X".

The N-hydroxysuccinimide ester (NHS) groups at either end of the PEG spacer react specifically and efficiently with lysine and N-terminal amino groups at pH 7-9 to form stable amide bonds. Other homobifunctional, sulfhydryl-reactive crosslinkers that contain the maleimide group at either end of a PEG spacer may be used to couple PEG to a Cys amino acid of a GIP receptor agonist peptide. Heterofunctional crosslinking spacer arms may also be used when two different reactive groups are used as the linkage groups, e.g. an amine group and a sulfhydryl group. A sulfhydryl-reactive crosslinker that contains a PEG spacer arm, may be used to couple a PEG polymer to a GIP receptor agonist peptide. In some embodiments, a bismaleimide-activated PEG compound may be used for crosslinking between sulfhydryl (-SH) groups in proteins and other thiol molecules. The maleimide groups at either end of the PEG spacer may react specifically and efficiently with reduced sulfhydryls at pH 6.5-7.5 to form stable thioether bonds. In other embodiments, direct coupling of a PEG molecule to a GIP receptor agonist peptide may be accomplished using known methods in the art. For example, a well known technique whereby a peptide may be covalently modified with PEG groups requiring 59057274.1PEG compounds that contain a reactive or targetable functional group at one end. The simplest method to pegylate peptides, which are rich in surface primary amines, is to use a PEG compound that contains an NHS ester group at one end, for example, a methyl-(PEG)n-NHS ester. In a similar fashion, methyl-(PEG)n-maleimide (wherein n can be from 20-300) may be used to couple a PEG molecule to a Cys containing peptide of the present disclosure.

[0462] New diagnostic criteria were reported by The Japan Diabetes Society in 1999 aboutthe diagnostic criteria of diabetes. 59057274.1
[0463] According to this report, diabetes refers to a state that meets any of a fasting bloodglucose level (glucose concentration in venous plasma) of 126 mg / dl or more, a 2-hr value (glucose concentration in venous plasma) of 200 mg / dl or more in the 75 g oral glucose tolerance test (75 g OGTT), and a casual blood glucose level (glucose concentration in venous plasma) of 200 mg / dl or more. Also, a state that does not apply to the above-mentioned diabetes, and is not a state exhibiting “a fasting blood glucose level (glucose concentration in venous plasma) less than 110 mg / dl or a 2-hr value (glucose concentration in venous plasma) less than 140 mg / dl in the 75 g oral glucose tolerance test (75 g OGTT)” (normal type) is called “borderline type”.
[0464] Moreover, new diagnostic criteria were reported by American Diabetes Association(ADA) in 1997 and by World Health Organization (WHO) in 1998 about the diagnostic criteria of diabetes.
[0465] According to these reports, diabetes refers to a state that meets a fasting bloodglucose level (glucose concentration in venous plasma) of 126 mg / dl or more and a 2-hr value (glucose concentration in venous plasma) of 200 mg / dl or more in the 75 g oral glucose tolerance test.
[0466] According to the above-mentioned reports, impaired glucose tolerance refers to astate that meets a fasting blood glucose level (glucose concentration in venous plasma) less than 59057274.1126 mg / dl and a 2-hr value (glucose concentration in venous plasma) of 140 mg / dl or more and less than 200 mg / dl in the 75 g oral glucose tolerance test. According to the report of ADA, a state exhibiting a fasting blood glucose level (glucose concentration in venous plasma) of 110 mg / dl or more and less than 126 mg / dl is called IFG (Impaired Fasting Glucose). On the other hand, according to the report of WHO, a state of the IFG (Impaired Fasting Glucose) exhibiting a 2-hr value (glucose concentration in venous plasma) less than 140 mg / dl in the 75 g oral glucose tolerance test is called IFG (Impaired Fasting Glycemia).
[0467] The GIP receptor agonist peptides of the present disclosure may also be used as anagent for the prophylaxis or treatment of diabetes determined according to the above-mentioned new diagnostic criteria, borderline type diabetes, impaired glucose tolerance, IFG (Impaired Fasting Glucose) and IFG (Impaired Fasting Glycemia). Moreover, the GIP receptor agonist peptides of the present disclosure can prevent progress of borderline type, impaired glucose tolerance, IFG (Impaired Fasting Glucose) or IFG (Impaired Fasting Glycemia) into diabetes.
[0468] The GIP receptor agonist peptides of the present disclosure are also useful as an agentfor the prophylaxis or treatment of metabolic syndrome. The incidence of cardiovascular disease is significantly high in metabolic syndrome patients, compared with patients with a single lifestyle-related disease. Thus, the prophylaxis or treatment of metabolic syndrome is 59057274.1exceedingly important for preventing cardiovascular disease.
[0469] The diagnostic criteria of metabolic syndrome were announced by the WHO in 1999and by NCEP in 2001. According to the diagnostic criteria of WHO, an individual having hyperinsulinemia or abnormal glucose tolerance as a requirement and two or more of visceral obesity, dyslipidemia (high TG or low HDL) and hypertension is diagnosed as having metabolic syndrome (World Health Organization: Definition, Diagnosis and Classification of Diabetes Mellitus and Its Complications. Part I: Diagnosis and Classification of Diabetes Mellitus, World Health Organization, Geneva, 1999). According to the diagnostic criteria of the Adult Treatment Panel III of the National Cholesterol Education Program (guideline of ischemic heart disease) in USA, an individual having three or more of visceral obesity, hypertriglyceridemia, low HDL- cholesterolemia, hypertension and abnormal glucose tolerance is diagnosed as having metabolic syndrome (National Cholesterol Education Program: Executive Summary of the Third Report of National Cholesterol Education Program (NCEP) Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults (Adults Treatment Panel III). The Journal of the American Medical Association, Vol.285, 2486-2497, 2001).

[0472] The GIP receptor agonist peptides of the present disclosure have low toxicity (e.g.,acute toxicity, chronic toxicity, genetic toxicity, reproductive toxicity, cardiac toxicity, carcinogenicity), shows a few side effects, and can be safely administered to a mammal (e.g., 59057274.1human, bovine, horse, dog, cat, monkey, mouse, rat) as an agent for the prophylaxis or treatment of emesis.
[0473] "Treatment," in the context of treating emesis by administering at least one of the GIPreceptor agonist peptides disclosed herein, includes both prophylactic treatment and the treatment of emesis after a subject experiences emesis. Prophylactic treatment includes administration of a GIP receptor agonist peptide before a subject experiences emesis, such as when the subject experiences nausea, as well as administration of the GIP receptor agonist peptide before the subject is exposed to a substance, agent, or event, or before the subject contracts a condition, which results in or is likely to result in the subject experiencing emesis. As used herein, "therapeutically effective amount" refers to an amount of the GIP receptor agonist peptide sufficient to elicit the desired biological response. In the present disclosure, the desired biological response is treating and / or preventing an abnormal glucose metabolism in a subject, for example, in a subject in need thereof, including diabetes and obesity, or the prevention and / or treatment of emesis in a subject in need thereof.

[0475] In order to prevent or treat emesis, an effective amount of one or more of the presentcompounds in a pharmaceutical composition is administered once per day, for example, once per 59057274.124 hours, to a subject / patient (used interchangeably herein) in need thereof. A subject is determined to be in need of treatment with the present GIP receptor agonist peptide either through observation of vomiting by the subject, or through a subject's self-reporting of emesis (in the case of a human subject). A patient is determined to be in need of preventative therapy by assessing that the patient is at risk of experiencing emesis due to another medical condition or due to exposure to an agent known to be associated with emesis, such as an infection by a virus or bacteria or chemical agent or radiation.
[0476] The present GIP receptor agonist peptides are beneficial in the therapy of acute,delayed or anticipatory emesis, including emesis induced by chemotherapy, radiation, toxins, viral or bacterial infections, pregnancy, vestibular disorders (e.g. motion sickness, vertigo, dizziness and Meniere's disease), surgery, pain, opioid use and withdrawal, migraine, and variations in intracranial pressure. The uses of the compounds disclosed herein are of benefit in the therapy of emesis induced by radiation, for example during the treatment of cancer, or radiation sickness, and in the treatment of post-operative nausea and vomiting. Most especially, use of the compounds disclosed herein is beneficial in the therapy of emesis induced by antineoplastic (cytotoxic) agents including those routinely used in cancer chemotherapy, emesis induced by other pharmacological agents, for example, alpha-2 adrenoceptor antagonists, such as 59057274.1yohimbine, MK-912 and MK-467, and type IV cyclic nucleotide phosphodiesterase (PDE4) inhibitors, such as RS14203, CT-2450 and rolipram.
[0477] Examples of chemotherapeutic agents are described, for example, by D. J. Stewart inNausea and Vomiting: Recent Research and Clinical Advances, ed. J. Kucharczyk et al., CRC Press Inc., Boca Raton, Fla., USA, 1991, pages 177-203, especially page 188. Commonly used chemotherapeutic agents include cisplatin, carboplatin, oxaliplatin, cyclophosphamide, dacarbazine (DTIC), dactinomycin, mechlorethamine (nitrogen mustard), streptozocin, cyclophosphamide, carmustine (BCNU), irinotecan, and other topoisomerase inhibitors, lomustine (CCNU), doxorubicin (adriamycin), daunorubicin, procarbazine, mitomycin, cytarabine, etoposide, methotrexate, 5-fluorouracil, vinblastine, vincristine, bleomycin, paclitaxel and chlorambucil (R. J. Gralle et al. in Cancer Treatment Reports, 1984, 68, 163-172). Emesis due to other chemical agents, such as the toxins soman or sarin, or opioid drug usage and / or withdrawal, e.g. morphine, heroin, oxycodone, and the like can also be prevented and / or treated.
[0478] The present compounds are administered to a patient in a quantity sufficient to treator prevent the symptoms and / or underlying etiology associated with emesis in the patient. In a preferred embodiment, the GIP receptor agonist peptides are administered prior to administration of an agent which is likely to cause emesis, such as one or more of the chemotherapeutic agents 59057274.1described above. The present GIP receptor agonist peptides can also be administered in combination with such agents, either in physical combination or in combined therapy through the administration of the present compounds and agents in succession (in any order). Although the presently disclosed compounds and forms thereof are useful in any mammal suffering from emesis, a preferred subject is a human.
[0479] In some embodiments, the selective GIPr agonists of the present disclosure may beadministered to treat emesis when a subject is concomitantly being treated for diabetes and / or obesity. Several known anti-diabetic medicaments are known for causing emesis, for example, Metformin (Glucophage, Glumetza, others), sulfonylureas, meglitinides, thiazolidinediones, DPP-4 inhibitors, SGLT2 inhibitors, and GLP-1 receptor agonists. In some embodiments, methods for treating emesis in a subject, for example in a subject in need thereof, may include administering an effective amount of a GIP receptor agonist peptide to a subject that does not have type-2 diabetes mellitus or a subject that is not taking a medicament to treat type-2 diabetes mellitus while experiencing emesis.
[0480] Nausea is a subjective unpleasant feeling in the back of one’s throat and stomach thatmay lead to vomiting. There are many words that describe nausea including, but not limited to: sick to my stomach, queasy, or upset stomach. Nausea can have other symptoms that happen at 59057274.1the same time, such as increased saliva (spit), dizziness, light-headedness, trouble swallowing, skin temperature changes, and a fast heart rate. Vomiting is also described as “throwing up.” When one vomits, one’s stomach muscles contract (squeeze) and push the contents of one’s stomach out through their mouth. One might or might not feel nauseated. Retching is when one tries to vomit without bringing anything up from one’s stomach. Other words used to describe retching are gagging or dry heaves. Nausea and vomiting often happen at the same time, but they can be 2 different conditions that may be mutually exclusive or mutually associated. Some chemotherapy drugs are more likely to cause nausea and vomiting than others. Doctors classify chemotherapy drugs according to their emetogenic potential (how likely the drug will cause nausea or vomiting) as high, moderate, low, or minimal risk.
[0481] In various embodiments, the GIPR agonist peptide compounds may be dosed onceper day to provide treatment and prophylactic treatment against emesis and emesis related symptoms. The peptide compounds of the present disclosure may be used to preferentially treat cyclic vomiting syndrome (CVS); chemotherapy induced nausea and vomiting (CINV) and post- operative nausea and vomiting (PONV). Cyclic vomiting syndrome (CVS) is a chronic functional gastrointestinal disorder that is being increasingly recognized in adults. It is characterized by episodic nausea and vomiting and is associated with significant morbidity. 59057274.1
[0482] An estimated 80% of patients with cancer will experience chemotherapy-inducednausea and vomiting (CINV). The term CINV includes emesis and nausea, which can involve a loss of appetite and result in decreased oral intake of fluids and calories. Five different types of CINV have been defined and include acute, delayed, breakthrough, anticipatory, and refractory CINV.
[0483] Postoperative nausea and vomiting (PONV) is the phenomenon of nausea, vomitingor retching experienced by a patient in the Post Anesthesia Care Unit (PACU) or 24-hours following a surgical procedure. It is an unpleasant complication that affects about 10% of the population undergoing general anaesthesia each year.
[0484] In an exemplary embodiment, the present disclosure provides for the prophylactictreatment or maintenance therapy for cyclic vomiting syndrome (CVS); chemotherapy induced nausea and vomiting (CINV) and post-operative nausea and vomiting (PONV), comprising administering one or more GIPR agonist peptide compounds of the present disclosure.

[0607] Example 6 - PYY-1119-Induced Emesis in Dogs
[0608] Female beagle dogs (20-43 months old) are fasted for approximately 16 hours andtransferred to an observation cage without food before each emetogen challenge. The dogs are weighed with an electronic balance, then test articles are administered via the subcutaneous route. The effects of single subcutaneous administration of the GIPR agonist compounds of the present disclosure on Neuropeptide Y2 receptor (Y2R) agonist compound PYY-1119 (PYY; 4- imidazolecarbonyl-Ser-D-Hyp-Iva-Pya(4)-Cha-Leu(Me)-Asn-Lys-Aib-Thr-Arg-Gln-Arg-Cha-NH2;10 μg / kg [about 5 nmol / kg]; s.c.) induced emesis are evaluated in dogs. The GIPR agonist peptidecompounds of the present disclosure and vehicles (1: 0.09% [w / v] Tween 80 / 10% DMSO / PBS; 2: 59057274.10.01mol / L PBS) are administered subcutaneously (sc) at different doses to dogs, followed by sc injections with PYY-1119 at 8 & 72 hours post-dose. Emesis symptoms are continuously recorded using a video camera and observations of symptoms include retching (a rhythmic contraction of the abdomen) and vomiting (vomiting behavior, including the elimination of vomitus or similar behavior). The combination of retching and vomiting is defined as emesis, and the number of episodes, latency (time elapsed from PYY administration until the onset of the first emesis symptom), duration (time elapsed between the onset of the first and final episodes of emesis), and frequency (number of animals showing emesis / number of experimental animals) of each of these symptoms was calculated. The latency in cases where emesis symptoms are not noted is taken as the maximum value (8 hours for PYY challenge) at the end of observation. When the duration of the emesis symptoms is less than 1 min, the duration is recorded, for convenience, as 1 min.
[0609] Emetic episodes (sum of retching and vomiting) are counted for 2 hours afteradministration (by blinded analysis).
[0610] The indicated compounds are each administered at 30 nmol / kg, all s.c.(subcutaneously), and the number of emetic events are indicated. In Table 4, each value represents the mean ± S.D. (n=4). The latency of a dog that did not show emetic response is considered as 120 min. The duration shown is the cumulative total duration of vomiting response. 59057274.1The vehicle is provided at 0.01 mol / L PBS 0.5 mL / kg, s.c. The compounds disclosed herein inhibit PYY-1119-induced emesis, including symptoms of vomiting.
[0611] Example 7: Morphine-Induced Emesis in Ferrets
[0612] 1. Effect of subcutaneously administered GIP receptor agonist peptide in morphine-induced acute emetic model.
[0613] The ferrets are weighed using an electronic balance and transferred to an observation cagewithout food and water approximately 30 minutes (min) after feeding. Approximately 30 min later, morphine was administered. Thereafter, for 1 hour post-administration, their emesis symptoms are macroscopically observed. At the same time, these symptoms are continuously recorded using a video camera. Observation symptoms included retching (rhythmic contraction of the abdomen), vomiting (vomiting behavior, including elimination of vomitus or similar behavior), licking (licking chops), and fidgeting (fidgety movements). The number of episodes and occurrences of these symptoms are recorded. In addition, the combination of retching and vomiting is defined as emesis, and the number of episodes, latency (time elapsed from morphine administration until the onset of the first emesis symptom), duration (time elapsed between the onset of the first and final episodes of emesis), and frequency (number of animals showing emesis / number of experimental animals) of each of these symptoms are calculated. The latency in cases where emesis symptoms are not noted 59057274.1is taken as the maximum value (30 min) at the end of observation. When the duration of the emesis symptoms is less than 1 min, the duration is recorded, for convenience, as 1 min.
[0614] GIP receptor agonist peptides are dissolved with a vehicle (0.09 w / v% tween 80 / 10%DMSO / saline), respectively, to prepare test solutions.0.5 mg / kg of the test solutions and the vehicle were subcutaneously administered to ferrets (4 in each group), respectively. At a time of 0.5 to 2 hours after administration, 0.6 mg / kg of morphine is subcutaneously administered. Up to 60 minutes after morphine administration, the condition of the ferrets was monitored to record the number of animals that did not vomit, the number of emetic episodes, the latency period in minutes to observe the emetic episodes, the duration of the observed emesis if any.
[0615] Example 8: Apomorphine Induced Emesis in Dogs
[0616] This Example shows the results of the administration of exemplary GIPR agonistcompounds (10, 30 and 100 nmol / kg, s.c., respectively) on apomorphine (0.1 mg / kg, s.c.)-induced emesis in dogs. The vehicle is provided at 0.01 mol / L PBS 0.5 mL / kg, s.c. In this study, dogs (8- 12 months old; n = 4) were transferred to an observation cage without food on 1 day before each emetogen challenge. The dogs are weighed by using an electronic balance then test articles will be administrated via the subcutaneous route. The GIPR agonist peptide compounds of the present disclosure and vehicle (0.01mol / L PBS) is administered subcutaneously (sc) at different doses to 59057274.1female beagle dogs followed by sc injections with apomorphine is challenged at 8 & 72 hours in the table post-dose. Emetic events were monitored for 1 h by video recording. Emesis symptoms are continuously recorded using a video camera and observations of symptoms included retching (a rhythmic contraction of the abdomen) and vomiting (vomiting behavior, including the elimination of vomitus or similar behavior). Besides, the combination of retching and vomiting is defined as emesis, and the number of episodes, latency (time elapsed from morphine administration until the onset of the first emesis symptom), duration (time elapsed between the onset of the first and final episodes of emesis), and frequency (number of animals showing emesis / number of experimental animals) of each of these symptoms is calculated. The latency in cases where emesis symptoms are not noted is taken as the maximum value (8 hours for apomorphine challenge) at the end of observation. When the duration of the emesis symptoms is less than 1 min, the duration is recorded, for convenience, as 1 min.
[0617] The compounds suppressed the apomorphine-induced emetic symptoms. In this tablebelow, results are shown as percent inhibition (%) at the dose of compound (nmol / kg) shown, at the hour(s) postdose of apomorphine, calculated as (1- (number of emetic episodes with peptide compound / number of emetic episodes with vehicle)) X 100.

[0619] Example 9: Human and Dog Plasma Protein Binding (PPB)
[0620] Stock Solutions
[0621] Stock solutions: (2000 µM) of the peptides are prepared in DMSO.
[0622] Plasma Protein Binding (PPB) Analysis
[0623] Human plasma (male; containing K2-EDTA as anti-coagulant; pre-adjusted to pH 7.4 -NB alternative species may be used) is spiked individually with each test peptide (2000 nmol / L), sampled for analysis and then incubated (n=4) at 37°C in a water bath for 30 minutes. Following the incubation period, the plasma is sampled for analysis, then transferred to ultracentifugation tubes and centrifuged (n=3) at -155,000g and 4°C for 4 hours, after which the supernatant is sampled for analysis. An additional aliquot of the supernatant is taken at the end of the centrifugation period to determine the total protein concentration. An aliquot of the incubated plasma will be stored at 4°C for 4 hours and then sampled for analysis. At the point of sampling, all samples are matrix-matched, treated with 4% phosphoric acid in water (1:1 (vfv)) containing internal standard, centrifuged at 2000g and 4°C for 10 minutes and stored prior to LC-MS / MS analysis. An appropriate positive control compound control will be incubated and centrifuged in parallel. Fraction unbound (Fu) values is determined by comparison of the analyte response in plasma to the analyte response in the 59057274.1supernatant, determined via peak area response ratios.
[0624] Sample Analysis
[0625] The samples are analyzed by LC-MS / MS using a 6500 (or equivalent) triple quadrupolemass spectrometer (AB Sciex) coupled to an appropriate Liquid Chromatography (LC) system. Protein binding and stability values are determined via peak area ratios using multiple reaction monitoring (MRM) parameters following compound optimization. Multiple reaction monitoring (MRM) is a highly sensitive method of targeted mass spectrometry (MS) that can be used to selectively detect and quantify peptides based on the screening of specified precursor peptide-to- fragment ion transitions.
[0626] Dog PPB values presented below are obtained essentially as described for Human PPBsamples, with the difference being that dog plasma was used instead of human serum. Table 8 is provided with the values of (Fu, plasma) as fraction unbound expressed as a percentage compared to the percent bound i.e. if the value is 0.0123, then the fraction unbound is (0.0123 / 100)%, which is 1.23% of the peptide is unbound and 98.77% is bound in plasma.
[0627] The GIPR agonist peptides of the present disclosure provide a percent of unbound oractive drug for antiemetic activity, which ranges from about 0.1% to about 10%. The efficacy of the GIPR agonist peptide will be related to the exposure to the amount of unbound drug in plasma, 59057274.1i.e. the proportion of free peptide to penetrate into surrounding tissues. The bound peptide in plasma can also serve as a reservoir for free peptide removed by various elimination processes thus prolonging the duration of action. GIPR agonist peptides of the present disclosure provide an optimum range of peptide unbound to plasma protein for once daily dosing to human subjects between 1-10% unbound. It is believed that GIPR agonist peptides of the present disclosure having a free fraction of about 1% to about 10% translates to a peptide having a desirable PK profile, demonstrating fast absorption and fast elimination to prevent excessive accumulation.
[0628] Example 10: Solubility of the GIPR Agonist Compounds
[0629] 3 mg of peptides are weighted out in a small glass vial. 100uL of 200mM Phosphatebuffer pH 7.4 are added and the vial is sonicated / vortexed as necessary for a maximum of 1 min. A visual inspection is performed, If the sample is fully dissolved, the solubility is recorded as 30mg / mL. If insoluble material is observed in the tube the addition of 100uL of buffer and mixing is repeated until complete dissolution. If the peptide is not soluble in 500uL of buffer, it is labeled as solubility < 6mg / mL.
