QD DOSING OF GIP RECEPTOR AGONIST PEPTIDE COMPOUNDS AND USES THEREOF

Abstract

The present disclosure provides GIP receptor agonist peptide compounds suitable for once per day dosing (QD), said peptide compounds having an activating action on GIP receptors and use of the GIP receptor agonist peptide as a medicament for the treatment and/or prevention of emesis, or a symptom or condition associated with emesis. Specifically, a GIP receptor agonist peptide containing a sequence represented by any of the formulas (I)-(V) or a salt thereof, and a medicament comprising the same are provided.

Description

TECHNICAL FIELD

The present disclosure relates to a novel peptide compound having an activating action on GIP receptors and use of the peptide compound as a medicament which may be dosed in a once daily dosing regimen.

BACKGROUND

The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

Both glucagon-like peptide-1 (GLP-1) and glucose-dependent insulinotropic polypeptide (GIP) are peptides called incretin. GLP-1 and GIP are secreted from small intestinal L cells and K cells, respectively.

GLP-1 acts via GLP-1 receptors and is known to have a glucose-dependent insulinotropic 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), though an influence of GIP only on feeding is not clear.

Attempts have been made to search for peptides having GLP-1 receptor/GIP receptor coagonist or glucagon receptor/GLP-1 receptor/GIP receptor triagonist activity and modifications thereof and develop these peptides as anti-obesity drugs, therapeutic drugs for diabetes, or therapeutic drugs for neurodegenerative disorders based on the structure of natural glucagon, GIP, or GLP-1. However, the peptide compound and the compound having a selective activating action on GIP receptors of the present disclosure for the use in treating emesis and similar symptoms associated with nausea and vomiting have not been disclosed.

Patients who experience nausea and vomiting are often unwilling or unable to take their medication regularly; several studies have shown that a less frequent dosing results in higher degree of compliance and thus eventually better treatment of the patients. Therefore, there is an unmet need for long acting preparations of antiemetic medicine. In particular there is a need for long 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 benefit in diseases where the duration of emetic episodes is longer.

All publications, patents, and patent applications cited herein are incorporated herein by reference in their entirety.

SUMMARY

It is an object of the present invention to provide a GIP receptor agonist peptide compound which has a GIP receptor activation action and is useful as a preventive/therapeutic agent for diabetes, obesity, and/or an antiemetic agent to prevent/treat diseases accompanied by vomiting or nausea.

The present disclosure provides GIPr agonist peptide compounds comprising a sequence represented by formulae (I)-(V) that are useful as therapeutic agents for the prevention or treatment of emesis as described herein. Surprisingly, the compounds of formulae (I)-(V) exhibit excellent GIP receptor activation action, a longer ½ life of elimination and improved solubility. Unexpectedly, in some instances, the peptides of formulae (I)-(V) 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)-(V) 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, possess improved properties in one or more of: (1) stability in serum, (2) half-life of elimination and (3) solubility.

As used herein, “PEG moiety” refers to polyethylene glycol (PEG) or a derivative thereof, for example (methoxy)polyethylene glycol (PEG_m).

As used herein, “PEGylated peptide” refers to a peptide wherein at least one amino acid residue, 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 MPEG moiety is said to be “mono-PEGylated”.

As used herein, “Lys-PEG” and “Lys-PEG_m” refer respectively to lysine residues which have 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.

In the present specification, the term “human native GIP peptide” refers to the naturally occurring human GIP peptide. This human native GIP peptide (42 amino acids) has an amino acid sequence: YAEGTFISDYSIAMDKIHQ QDFVNWLLAQKGKKNDWKHNITQ (SEQ ID NO: 1) and 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.

“Percent (%) amino acid sequence identity” with respect to a reference polypeptide sequence 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.

As used herein, “treatment” (and variations such as “treat” or “treating”) refers to clinical intervention in an attempt to alter the natural course of the individual being treated, and can 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.

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 relative reduction of a side effect (i.e. nausea and/or vomiting) associated with a treatment for a condition or disease.

Optimal alignment of sequences for comparison can be conducted, for example, by the local 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)).

One illustrative example of an algorithm that is suitable for determining percent sequence 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 analyses 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.

In addition to calculating percent sequence identity, the BLAST algorithm also performs 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.

Variants can also be synthetic, recombinant, or chemically modified polynucleotides or 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. The 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.

“Conservative amino acid substitutions” as referenced herein result from replacing one amino 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 acid (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.

In alternative embodiments, one can also select conservative amino acid substitutions encompassed 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, S 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.

As used herein, the term “selectivity” of a molecule for a first receptor relative to a second receptor refers to the following ratio: EC₅₀ of 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.

As is understood by one skilled in the art, reference to “about” a value or parameter herein 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”.

It is understood that aspect and embodiments of the disclosure described herein include “consisting” and/or “consisting essentially” of aspects and embodiments. As used herein, the singular form “a”, “an”, and “the” includes plural references unless indicated otherwise.

The N-hydroxysuccinimide ester (NHS) groups at either end of the mPEG 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 PEG 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.

The peptide synthesis method may be any of, for example, a solid phase synthesis process and a liquid phase synthesis process. That is, the object GIP receptor agonist peptide can be produced by repeating condensation of a partial peptide or amino acid capable of constituting the GIP receptor agonist peptide, and the remaining portion (which may be constituted by two or more amino acids) according to a desired sequence. When a product having the desirable sequence has a protecting group, the object GIP receptor agonist peptide can be produced by eliminating a protecting group. Examples of the condensing method and eliminating method of a protecting group to be known include methods described in the following (1)-(5).

Protection of a functional group that should not be involved in the reaction of a starting material and a protecting group, elimination of the protecting group, activation of a functional group involved in the reaction and the like can be appropriately selected from known protecting groups and known means.

In a method of preparing an amide of the peptide, it is formed by a solid phase synthesis using a resin for amide synthesis, or the α-carboxyl group of the carboxy terminal amino acid is amidated, and a peptide chain is elongated to a desired chain length toward the amino group side, thereafter a peptide wherein the protecting group for the N-terminal α-amino group of the peptide chain only removed and a peptide wherein the protecting group for the C-terminal carboxyl group only removed of the peptide chain are prepared, and the both peptides are condensed in a mixed solvent described above. For details about the condensation reaction, the same as above applies. After the protected peptide obtained by the condensation is purified, all protecting groups can be removed by the above-described method to yield a desired crude polypeptide. By purifying this crude peptide using various publicly known means of purification, and freeze-drying the main fraction, a desired amide of the peptide can be prepared.

New diagnostic criteria were reported by The Japan Diabetes Society in 1999 about the diagnostic criteria of diabetes.

According to this report, diabetes refers to a state that meets any of a fasting blood glucose 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”.

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.

According to these reports, diabetes refers to a state that meets a fasting blood glucose 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.

According to the above-mentioned reports, impaired glucose tolerance refers to a state that meets a fasting blood glucose level (glucose concentration in venous plasma) less than 126 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).

The GIP receptor agonist peptides of the present disclosure may also be used as an agent 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.

The GIP receptor agonist peptides of the present disclosure are also useful as an agent for 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 exceedingly important for preventing cardiovascular disease.

The diagnostic criteria of metabolic syndrome were announced by WHO in 1999 and 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).

More specifically, the GIP receptor agonist peptides of the present disclosure have an antiemetic action, and may inhibit or reduce the number and severity of the occurrence of nausea, and/or vomiting when associated with various stimuli disclosed herein, for example, when a subject has cyclic vomiting syndrome or is administered a chemotherapeutic drug, for example, a chemotherapeutic drug with emetic potential, such as platinum based chemotherapeutics such as cisplatin, oxaliplatin, and carboplatin; irinotecan and other topo isomerase inhibitors used in the treatment of cancer. The GIP receptor agonist peptides of the present disclosure have a high chemical stability and excellent persistence of the effects in vivo.

The GIP receptor agonist peptides of the present disclosure may be used as a GIP receptor activator. In the present disclosure, the GIP receptor activator (GIP receptor agonist) means an agent having a GIP receptor activation action. Additionally, the GIP receptor selective activator (i.e. a GIP receptor agonist as used herein) specifically means an agent having an EC₅₀ for the GIP receptor of 1/1000 or less, or 1/10000 or less, times the EC₅₀ for the GLP-1 receptor, or in other words the ratio of EC₅₀ GLP1R/EC₅₀ GIPR is greater than 10, greater than 100, or greater than 1,000, or greater than 10,000, or from 100 to 1,000,000 or more.

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., human, bovine, horse, dog, cat, monkey, mouse, rat) as an agent for the prophylaxis or treatment of emesis.

“Treatment,” in the context of treating emesis by administering at least one of the GIP receptor 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 various embodiments, the subject, for example, a mammal, for example, humans, non-human primates, apes, monkeys, laboratory mammals for example, mice, rats, rabbits, guinea-pigs, ferrets, domesticated mammals, such as companion mammals, dogs, cats and horses, and farm mammals, such as cattle, pigs, sheep and goats purely as examples, but not intended to be an exhaustive list, may be treated with a GIP receptor agonist peptide of the present disclosure. In each of these cases, the methods of the present disclosure are provided to treat or prevent diabetes, obesity, or emesis in a subject in need thereof, to reduce or inhibit diabetes, obesity, or emesis, to reduce or inhibit a symptom associated with diabetes, obesity, or emesis, or to reduce or inhibit a pathological condition or symptom associated with diabetes, obesity, or emesis, for example, nausea and/or vomiting.

In order to prevent or treat emesis, an effective amount of one or more of the present compounds in a pharmaceutical composition is administered once per day 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.

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 this invention 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 invention 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 yohimbine, MK-912 and MK-467, and type IV cyclic nucleotide phosphodiesterase (PDE4) inhibitors, such as RS14203, CT-2450 and rolipram.

Examples of chemotherapeutic agents are described, for example, by D. J. Stewart in Nausea 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 opiod drug usage and/or withdrawal, e.g. morphine, heroin, oxycodone, and the like can also be prevented and/or treated.

The present compounds are administered to a patient in a quantity sufficient to treat or 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 described 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 present invention is useful in any mammal suffering from emesis, a preferred subject is a human.

In some embodiments, the selective GIPr agonists of the present disclosure may be administered 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.

Nausea is a subjective unpleasant feeling in the back of one's throat and stomach that may 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 the 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.

In various embodiments, the GIPR agonist peptide compounds may be dosed once per 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.

An estimated 80% of patients with cancer will experience chemotherapy-induced nausea 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.

Postoperative nausea and vomiting (PONV) is the phenomenon of nausea, vomiting or 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.

In an exemplary embodiment, the present disclosure provides for the prophylactic treatment 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, for example, a GIPR agonist peptide compound selected from compound 17, 25, 21, 48, 142, 14 and 20, in a therapeutically effective amount to a subject in need thereof.

The GIP receptor agonist peptides of the present disclosure may be used as a preventive/therapeutic agent, ie. prophylactic treatment or maintenance therapy for vomiting and/or nausea caused, for example, by clinical pathological conditions or causes described in the following

The GIP receptor agonist peptides of the present disclosure may be used as a preventive/therapeutic agent for vomiting and/or nausea caused, for example, by clinical pathological conditions or causes described in the following (1) to (10). Additionally, the GIP receptor agonist peptide of the present disclosure may be used as a preventive/therapeutic agent for chronic unexplained nausea and vomiting.

Peptide Cleavage and Purification:

1. The resin was washed with MeOH (30 mLtimes2) and dried under vacuum to get 3.5 g peptide resin. Then 30 mL of cleavage buffer (92.5% TFA/2.5%₀ 3-Mercaptopropionic acid/2.5% TIS/2.5% H2O) was added to the flask containing the side chainprotected peptide resin at 20° C. and the mixture was stirred for 2 h. The peptide was precipitated with cold tert-butyl methylether (250 mL) and centrifuged (3 min at 3000 rpm). Wash the peptide precipitation with tert-butyl methyl ether for two more times (120 mL). Dry the crude peptide (1.4 g) over vacuum for 2 h.

2. The residue was purified by prep-HPLC (TFA condition; 30° C., A: 0.07500 TFA/1H2O, B: CH3CN) and then was second purified by prep-HPLC (HOAc condition; 30° C., A: 0.5% HOAc/H2O, B: CH3CN) to give the product to give the compound 14 (79.8 mg, 6.22% yield, 96.4% purity, HOAC) as a white solid.

Biological Examples

Methods for performing GIP and GLP receptor binding assays, assays for inhibition of emesis, vomiting and nausea, caused by various stimuli, including from drug or chemotherapy induced emesis are specifically described in Applicant's International PCT Application No. PCT/JP2018/013540, filed on Mar. 30, 2018, ranging from pages 213 to 255, and are specifically incorporated herein by reference in their entirety.

Example 8-Evaluation of Peptide Agonist Activity on Human GIPR and Human GLP1R by Measuring Intracellular cAMP Accumulation

GIPR Assay

HEK-293T cells overexpressing full-length human GIPR with a sequence identical to GenBank accession number NM_000164 with an N-terminal FLAG tag are purchased from Multispan, Inc (Hayward, Calif.). Cells are cultured per the manufacturer's protocol in DMEM with 10% fetal bovine serum and 1 μg/mL puromycin and stored in frozen aliquots to be used as assay ready cells. On the day of the assay, cells are removed from frozen storage, washed two times in 1× Kreb's Ringer Buffer (Zenbio, Research Triangle Park, N.C.), and re-suspended to a concentration of 4×10⁵ cells/mL in 1× Kreb's Ringer Buffer. 50 nL of test compound in 100% DMSO spanning a final concentration range of 3×10⁻¹⁰-5.08×10⁻¹⁵ M are acoustically dispensed in low volume, white, 384-well polypropylene plates (Corning, Tewksbury, Mass.), followed by the addition of 4×10³ cells per well in total volume of 10 μL. Cells are incubated with test compound for 1 hr at room temperature in the dark, and cAMP accumulation is measured using the Cisbio HiRange cAMP assay kit (Bedford, Mass.) per the manufacturer's protocol. Anti-cAMP antibody and d2-cAMP tracer reagents diluted in lysis/detection buffer are incubated in the dark for 1 hr, and results are measured on an Envision plate reader (Perkin Elmer, Waltham, Mass.). Data is normalized using 1 nM GIP as 100% activity, and DMSO alone as 0% activity.

HEK-293T cells overexpressing full-length human GLP-1R with a sequence identical to GenBank accession number NM_002062 with an N-terminal FLAG tag may be purchased from Multispan, Inc (Hayward, Calif.). Cells are cultured per the manufacturer's protocol in DMEM with 100 fetal bovine serum and 1 μg/mL puromycin and stored in frozen aliquots to be used as assay ready cells. On the day of the assay, cells are removed from frozen storage, washed two times in 1× Kreb's Ringer Buffer (Zenbio, Research Triangle Park, N.C.), and re-suspended to a concentration of 4×10⁵ cells/mL in 1× Kreb's Ringer Buffer. 50 nL of test compound in 100% DMSO spanning a final concentration range of 1×10⁻⁶-1.69×10⁻¹¹ M are acoustically dispensed in low volume, white, 384-well polypropylene plates (Corning, Tewksbury, Mass.), followed by the addition of 4×10³ cells per well in total volume of 10 μL. Cells are incubated with test compound for 1 hr at room temperature in the dark, and cAMP accumulation is measured using the Cisbio HiRange cAMP assay kit (Bedford, Mass.) per the manufacturer's protocol. Anti-cAMP antibody and d2-cAMP tracer reagents diluted in lysis/detection buffer are incubated in the dark for 1 hr, and results are measured on an Envision plate reader (Perkin Elmer, Waltham, Mass.). Data is normalized using 1 nM GLP-1 as 100% activity, and DMSO alone as 0% activity.

Table 4 provides the selective binding activity of the GIPR agonist peptides of the present disclosure. As can be seen, the peptide compounds provided here have a human GLP1R cAMP EC₅₀/human GIPR cAMP EC₅₀ ratios ranging from about 800 to about 10,000,000, thus indicating incredibly selective GIPR agonist binding activity. Most of the GIPR agonist peptide compounds display Human GLP1R cAMP EC₅₀/Human GIPR cAMP EC₅₀ ratios of greater than 1,000, or greater than 5,000, or greater than 10,000, or greater than 50,000, or greater than 100,000, or greater than 500,000.

Example 9. Oral Glucose Tolerance Test

An oral glucose tolerance test (OGTT) was carried out using C57BL/6J mice with a glucose load of 2.5 g/kg by oral administration. Testing concentrations of 0.1, 0.3 or 3 nmol/kg were selected depending on the peptide. Each peptide or a vehicle (control group) was subcutaneously administered 30 mi before glucose loading and the blood glucose levels were measured at 15, 30, 60 and 120 min post oral glucose administration to evaluate the action of the compound. The action of the compound was calculated by the calculation formula below and expressed as the 0% drop in glucose as measured over 120 min using AUC.

% inhibition=(1−(AUC cpd/AUC vehicle))×100.

Results are shown in Table 5. As shown in Table 5, it is verified that the compounds of the present invention suppress increase in blood glucose level caused by oral glucose loading.

Example 10: PYY-1119-Induced Vomiting in Dogs

Effects of single subcutaneous administration of the GIPR agonist compounds of the present disclosure on Neuropeptide Y2 receptor (Y2R) agonist compound PYY-1119 (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 were evaluated in dogs. The GIPR agonist peptide compounds of the present disclosure or vehicle (0.09% [w/v] Tween 80/10% DMSO/PBS) was administered subcutaneously (sc) at different doses to female beagle dogs (10 months old), followed by sc injections with Y2R agonist ((4-imidazolecarbonyl-Ser-D-Hyp-Iva-Pya(4)-Cha-Leu(Me)-Asn-Lys-Aib-Thr-Arg-Gln-Arg-Cha-NH2), 10 μg/kg), 10 μg/kg) at 1 hour or specified hours in the table postdose. Emetic episodes were counted for 2 hours after administration (by blinded analysis).

Table 6 shows the compounds suppressed the PYY-1119-induced emetic symptoms. In the below table, results are shown as percent inhibition (%) at the dose of compound (nmol/kg) shown, at the hour(s) postdose of PYY-1119, calculated as (1−(number of emetic episodes with peptide compound/number of emetic episodes with vehicle))×100.

Example 12: Vomiting Suppression Test in Ferrets

1. Effect of subcutaneously administered GIP receptor agonist peptide in morphine-induced acute emetic model.

To evaluate the antiemetic effect, the GIP receptor agonist peptides compounds 25, 14, 142, 48, 17 and 20 other than natural human GIP are subcutaneously administered into male ferrets 30 minutes before morphine administration. Up to 60 minutes after morphine administration, the condition of the ferrets is monitored to record the frequencies and time points of abdominal contraction motions, vomiting behaviors, licking with the tongue, and fidgety behavior occurring.

GIP receptor agonist peptide compounds of the present disclosure are dosed at 0.1-10 nmol/kg to attenuate the morphine (0.6 mg/kg, s.c.)-induced emesis in the ferrets.

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 are subcutaneously administered to ferrets (4 in each group), respectively. At the time of each of 4 hours, after administration, 0.6 mg/kg of morphine is subcutaneously administered. Up to 60 minutes after morphine administration, the condition of the ferrets is 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.

Results from the above morphine induced emesis example, clearly illustrate that Compounds 14 (SEQ ID NO: 15), Compound 48 (SEQ ID NO:), Compound 25 (SEQ ID NO: 26), and Compound 142 (SEQ ID NO: 143) are effective in inhibiting the frequency of emetic events, including frequency of both retching and vomiting events in ferrets dosed with morphine.

Example 13: Apomorphine Induced Emesis in Dog

Dogs are transferred to an observation cage (700 mm W×700 mm D×700 mm H [W×D×H], without food) on 1 day before each apomorphine challenge. The dogs are weighed by using an electronic balance then test articles will be administrated via the subcutaneous route. Apomorphine is challenged at 8 hr after the administration and emetic events will be monitored for 1 h by video recording. The second apomorphine challenge will be 72 hr after the administration and emetic events will be recorded by the same protocol. Emesis symptoms are continuously recorded using a video camera and stored on a blue ray disc. Observations of symptoms include 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 (1 h 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.

Example 14: Serum Half-Life and Percentage Remaining at 48 Hours

Serum Half-Life Analysis

Human plasma (mixed gender: sodium heparin is used as anti-coagulant; pre-adjusted to pH 7.4—NB alternative species may be used) is spiked with each test peptide (500 nM) and incubated ·cn=3) at 37° C. for 48 hours in a 5% CO2 environment. Aliquots are taken at 0. 1, 2, 4, 7, 24 and 46 hours and pH adjusted to pH 3 with 20% formic acid prior to analysis. Appropriate positive control compounds will be incubated in parallel, in addition to a no plasma control, sampled at 0 and 8 hours. All samples will be treated with ice-cold acetonitrile/methanol (4:1 (v/v)) containing internal standard prior to centrifugation at 2000 g and 4° C. for 10 minutes and subjected to LC-MS/MS analysis.

Sample Analysis

The samples are analyzed by LC-MS/MS using a 6500 (or equivalent) triple quadrupole mass 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 optimisation. 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.

Table 15 provides two data points related to the pharmacokinetic activity of the GIPR agonist peptides of the present disclosure. Optimum values for the use of the GIPR agonist peptides of the present disclosure range between a serum T½ (half life) of 10-20 hours for once daily dosing. As can be seen from Table 15, when the T½ in serum approaches 30 hours and greater, the amount remaining after 48 hours exceeds 30%, which indicates that the peptide is accumulating and not being made available to exert its pharmacological activity.

Example 15: Human Plasma Protein Binding (PPB)

Stock Solutions

Stock solutions: (1000 μM) of the peptides are prepared in DMSO.

Plasma Protein Binding (PPB) Analysis

Human plasma (mixed gender; 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 (1000 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 ultracentrifugation tubes and centrifuged (n=3) at −450,000 g and 4° C. for 3 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 3 hours and then sampled for analysis. At the point of sampling, all samples are matrix-matched, treated with ice-cold acetonitrile/methanol (4:1 (vfv)) containing internal standard, centrifuged al 2000 g 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; control plasma is also centrifuged to generate samples for matrix-matching. Fraction unbound (Fu) values is determined by comparison of the analyte response in plasma to the analyte response in the supernatant, determined via peak area response ratios.

Plasma Stability Analysis

Human plasma (mixed gender: sodium heparin is used as anti-coagulant; pre-adjusted to pH 7.4—NB alternative species may be used) is spiked with each test peptide (500 nM) and incubated ·cn=3) at 37° C. for 48 hours in a 5% CO2 environment. Aliquots are taken at 0. 1, 2, 4, 7, 24 and 46 hours and pH adjusted to pH 3 with 20% formic acid prior to analysis. Appropriate positive control compounds will be incubated in parallel, in addition to a no plasma control, sampled at 0 and 8 hours. All samples will be treated with ice-cold acetonitrile/methanol (4:1 (v/v)) containing internal standard prior to centrifugation at 2000 g and 4° C. for 10 minutes and subjected to LC-MS/MS analysis.

Dog PPB values presented below are obtained essentially as described for Human PPB samples, with the difference being that dog serum is used instead of human serum. Table 16 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.

As can be seen in Table 16, the GIPR agonist peptides of the present disclosure provide a percent of unbound or active drug for antiemetic activity, which ranges from about 0.1% to about 7.3%. The efficacy of the GIPR agonist peptide will be related to the exposure to the amount of unbound drug in plasma, i.e. the proportion 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. These GIPR agonist peptides also demonstrate that due to the high proportion of the drug being bound (98.9% to 92.7%), the duration of action can be extended for longer periods of time. GIPR agonist peptides of the present disclosure provide an optimum range of unbound to plasma protein for once daily dosing to human subjects between 1-5% unbound. It is believed that GIPR agonist peptides of the present disclosure having a free fraction of about 1% to about 5% translates to a peptide having a desirable pK profile, demonstrating fast absorption and fast elimination to prevent excessive accumulation. Several compounds in Table 16 demonstrate optimum free unbound peptide, for example, compounds 14, 16, 18, 19, 21, 22, 24, 25, and 30.

Example 16: Solubility of the GIPR Agonist Compounds

3 mg of peptides are weighted out in a small glass vial. 100 uL of 200 mM Phosphate buffer 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 30 mg/mL. If insoluble material is observed in the tube the addition of 100 uL of buffer and mixing is repeated until complete dissolution. If the peptide is not soluble in 500 uL of buffer, it is labeled as solubility <6 mg/mL. The solubility can be confirmed by RP-HPLC after filtration on 0.2 μm filter on an Agilent 1200 system with a Kinetex column form Phenomenex® (2.6 μm EVO C18 100 Å, LC Column 50×3.0 mm) kept at 40° C., the eluent A is 0.05% TFA in Water, B is 0.035% TFA in Acetonitrile at a 0.6 ml/min flow rate. The gradient was from 20 to 70 over 5 min, the column is then washed for 1 min at 90% B. UV monitoring at 215 nm was used to monitor peptide concentration.

As shown in Table 17, several of the tested GIPR agonist peptides demonstrate high solubility in physiological buffer (Phosphate buffer at pH 7.4) of 15 mg/mL and above. Compounds 1-189 exhibit a solubility in phosphate buffer at pH 7.4 of 15 mg/mL or greater, which are the preferred compounds for dosing in volumes that facilitate once per day or QD dosing. Compounds having a solubility of less than 15 mg/mL, for example less than 15 mg/mL, or from 10 mg/mL to 15 mg/mL are less preferred, and peptide compounds having less than 10 mg/mL solubility as described in Example 16 are excluded from the GIPR agonist peptides that are suitable for QD dosing. In some embodiments, GIPR agonist peptide compounds of the present disclosure having less than 15 mg/mL solubility as described in Example 16 are excluded from the GIPR agonist peptides that are suitable for QD dosing.

Example 17: Summary of Pharmacokinetic (PK) and Pharmacodynamic (PD) Studies of Selective GIP Receptor Agonist Peptides

Pharmacokinetic (PK) were conducted in dog in order to determine the half-life after IV and SC dosing. The peptide was dissolved in 10% DMSO/0.09% Polysorbate/PBS pH 7.4 to a concentration of 3 nmol/mL and the animal were dose with a volume of 1 mL/kg SC or IV. Blood sample were collected at 0, 0.0330, 0.0830, 0.250, 0.500, 1.00, 2.00, 4.00, 6.00, 8.00, 12.0, 24.0, 48.0 hours for IV dosing and 0.250, 0.500, 1.00, 2.00, 4.00, 6.00, 8.00, 12.0, 24.0, 48.0 for SC dosing, EDTA-K2 was used as anticoagulant. The plasma concentration of the peptide was measured using LCMS. Allometric scaling of lipidated peptide pharmacokinetics including T½ and MRT is known in the art for rodent to dog and mini pig and to humans. In one illustrative embodiment, a lipidated peptide was shown to have MRT=16.5 hrs following s.c. dosing in dog and is dosed QD in humans. See for example, Discovery and Development of Liraglutide and Semaglutide. Knudsen, L. B.; Lau, J. Frontiers in Endocrinology, 2019, vol 10, Article 155.
