[0005] The present invention relates to isolated polypeptides that are analogs of human amylin. The disclosed amylin analog polypeptides have advantageous physicochemical properties relative to endogenous amylin, such as a longer elimination half-life (t 1 / 2 ) and improved solubility and thermal stability. The present invention also relates to methods of using the amylin analog polypeptides disclosed herein in a variety of therapeutic indications, as well as methods of making the same. As explained in more detail below, the disclosed amylin analog polypeptides are particularly useful in treating metabolic diseases or conditions such as type 1 and type 2 diabetes and in providing methods of weight loss. Background Art
[0006] Human amylin, or islet amyloid polypeptide (IAPP), is a 37-residue polypeptide hormone. Amylin is co-secreted from pancreatic beta cells along with insulin at a ratio of approximately 100:1 (insulin:amylin). Pro-islet amyloid polypeptide (i.e., pro-IAPP) is produced in pancreatic beta cells as a 67 amino acid, 7404 dalton pro-peptide that undergoes post-translational modifications (including protease cleavage) to produce the 37-residue amylin. Loss of beta cell function, which occurs in patients with type 1 diabetes early in life and may occur in patients with type 2 diabetes late in life, leads to inadequate secretion of both insulin and amylin.
[0007] Amylin is part of the endocrine pancreas (the cells within the pancreas that synthesize and secrete hormones). Amylin contributes to blood sugar control; it is secreted from the pancreatic islets into the blood circulation and cleared by peptidases in the kidneys. Amylin's metabolic function is well characterized as an inhibitor of the appearance of nutrients such as glucose in the plasma. It thus acts as a co-partner to insulin, a peptide that regulates blood sugar levels and coordinates the body's distribution and uptake of glucose. Insulin's role in the body is, among other things, to prevent blood sugar levels from rising too high, especially after a meal.
[0008] Amylin is thought to play a role in blood sugar regulation by slowing gastric emptying and promoting satiety (i.e., a feeling of fullness), thereby preventing a postprandial (i.e., after a meal) spike in blood sugar levels. The overall effect is to slow the rate at which glucose appears in the blood after a meal. Amylin also reduces the secretion of glucagon by the pancreas. Glucagon's role in the body is, among other things, to prevent blood sugar levels from falling too low. This is important because, for example, some people with type 1 diabetes tend to secrete excess amounts of glucagon, which raises blood sugar levels, immediately after a meal.
[0009] For a number of reasons, human amylin, which has a half-life of approximately 13 minutes in serum, is not suitable for use as a therapeutic agent. Instead, pramlintide ( Pramlintide (developed by Amylin Pharmaceuticals, Inc., San Diego, CA, USA, and sold by AstraZeneca plc, Cambridge, UK) is a synthetic analog of human amylin for the treatment of patients with type 1 or type 2 diabetes who, despite optimal insulin therapy, are unable to achieve desired glycemic control using mealtime insulin. Pramlintide differs from human amylin in three of its 37 amino acids. These modifications provide pramlintide with a longer half-life of approximately 48 minutes in humans and reduce its tendency to aggregate, a characteristic found in human amylin.
[0010] For the treatment of patients with type 1 diabetes, pramlintide is administered up to four times daily via subcutaneous injection before meals as an adjunct to insulin therapy administered after meals. Pramlintide cannot be mixed with insulin; a separate syringe is used. Reported side effects of pramlintide include nausea and vomiting. Adverse reactions may include severe hypoglycemia, particularly in patients with type 1 diabetes. Therefore, for patients starting pramlintide, the mealtime insulin dose is reduced.
[0011] For the treatment of patients with type 2 diabetes, pramlintide is administered via subcutaneous injection before each meal at a recommended starting dose that is gradually increased to the target maintenance dose. The other investigational analog of human amylin, davalintide (AC2307; also being developed by Amylin Pharmaceuticals, Inc.), has a half-life of approximately 26 minutes.
[0012] Therefore, there is a need for improved amylin analog polypeptides that mimic the activity of amylin but have greater therapeutic potential than endogenous human amylin and existing amylin analogs such as pramlintide and davalintide. Summary of the Invention

[0034] Table 1: Naturally occurring amino acids
[0035]
[0036] Peptides can be naturally occurring, synthetically produced, or recombinantly expressed. Peptides can also contain additional groups that alter the amino acid chain, such as functional groups added via post-translational modification. Examples of post-translational modifications include, but are not limited to, acetylation, alkylation (including methylation), biotinylation, glutamylation, glycation, glycosylation, prenylation, lipidation, phosphopantetheinylation, phosphorylation, selenoylation, and C-terminal amidation. The term peptide also includes peptides containing modifications at the amino and / or carboxyl termini. Modifications of the terminal amino group include, but are not limited to, des-amino, N-lower alkyl, N-di-lower alkyl, and N-acyl modifications. Modifications of the terminal carboxyl group include, but are not limited to, amide, lower alkylamide, dialkylamide, and lower alkyl ester modifications (e.g., where the lower alkyl group is C1-C4 alkyl). The term peptide also includes modifications, such as, but not limited to, those described above, of the amino acids between the amino and carboxyl termini. In one embodiment, the peptide can be modified by the addition of a small molecule drug.
[0037] The terminal amino acid at one end of the peptide chain typically has a free amino group (i.e., the amino terminus). The terminal amino acid at the other end of the chain typically has a free carboxyl group (i.e., the carboxyl terminus). Typically, the amino acids that make up a peptide are numbered sequentially, starting from the amino terminus and increasing toward the carboxyl terminus of the peptide.
[0038] As used herein, the phrase "amino acid residue" refers to an amino acid that is incorporated into a peptide via an amide bond or an amide bond mimetic.
[0039] As used herein, the term "insulinotropic" generally refers to the ability of a compound (e.g., a peptide) to stimulate or affect the production and / or activity of insulin (e.g., insulinotropic hormone). Such compounds generally stimulate or otherwise affect the secretion or biosynthesis of insulin in a subject. Thus, an "insulinotropic peptide" is an amino acid-containing molecule that is capable of stimulating or otherwise affecting the secretion or biosynthesis of insulin.
[0040] The term "insulinotropic peptide" as used herein includes, but is not limited to, glucagon-like peptide 1 (GLP-1) and its derivatives and analogs; GLP-1 receptor agonists, such as exenatide, exenatide having the amino acid sequence of SEQ ID NO: 307, and its derivatives and analogs.
[0041] As used herein, the term "acylated" with respect to the disclosed polypeptides means that the disclosed polypeptides are each optionally substituted with one or more lipophilic substituents via a spacer, wherein "lipophilic substituent" and "spacer" are defined herein. Certain lipophilic substituents, each optionally via a spacer, can bind to albumin and impart an affinity for the resulting acylated polypeptide. The extent to which the lipophilic substituents, each optionally via a spacer, bind to albumin and impart an affinity for the resulting acylated polypeptide is variable and depends on numerous factors, including the identity of the lipophilic substituent, the optional spacer, the polypeptide, and the site of covalent attachment to the polypeptide.
[0042] As used herein, the term "linear" or "linear polypeptide" refers to a "non-acylated" polypeptide, in other words, a disclosed amylin analog polypeptide that does not each have a lipophilic substituent, optionally via a spacer, wherein "lipophilic substituent" and "spacer" are defined herein.
[0043] As used herein, the term "conjugated" or "conjugated polypeptide" refers to an "acylated" polypeptide, in other words, a disclosed amylin analog polypeptide, each having one or more lipophilic substituents, optionally via a spacer, wherein "lipophilic substituent" and "spacer" are defined herein.
[0044] As used herein, the term "pharmaceutically acceptable salt" refers to salts that are suitable for use in contact with the tissues of humans and lower animals without excessive toxicity, irritation, allergic reactions, etc., and that are commensurate with a reasonable benefit / risk ratio, within the scope of reasonable medical judgment. Pharmaceutically acceptable salts are well known in the art. For example, SM Berge et al. describe pharmaceutically acceptable salts in detail in J. Pharmaceutical Sciences, 1977, 66, 1-19, which are incorporated herein by reference. Pharmaceutically acceptable salts of the compounds of the present invention include those derived from suitable inorganic and organic acids and bases. Examples of pharmaceutically acceptable non-toxic acid addition salts are amino salts formed with inorganic acids such as hydrochloric acid, hydrobromic acid, phosphoric acid, sulfuric acid, and perchloric acid, or with organic acids such as acetic acid, trifluoroacetic acid (TFA), oxalic acid, maleic acid, tartaric acid, citric acid, succinic acid, or malonic acid, or by using other methods used in the art, such as ion exchange. Other pharmaceutically acceptable salts include adipate, alginate, ascorbate, aspartate, benzenesulfonate, benzoate, bisulfate, borate, butyrate, camphorate, camphorsulfonate, citrate, cyclopentanepropionate, digluconate, dodecylsulfate, ethanesulfonate, formate, fumarate, glucoheptonate, glycerophosphate, gluconate, hemisulfate, heptanoate, hexanoate, hydroiodide, 2-hydroxy-ethanesulfonate, lactobionate, lactate, laurate, lauryl sulfate, malate, maleate, malonate, methanesulfonate, 2-naphthalenesulfonate, nicotinate, nitrate, oleate, oxalate, palmitate, pamoate, pectinate, persulfate, 3-phenylpropionate, phosphate, pivalate, propionate, stearate, succinate, sulfate, tartrate, thiocyanate, p-toluenesulfonate, undecanoate, valerate, and the like.
[0045] Salts derived from appropriate bases include alkali metal salts, alkaline earth metal salts, ammonium salts and N+(C1-4 alkyl)4 salts. Representative alkali metal salts or alkaline earth metal salts include sodium salts, lithium salts, potassium salts, calcium salts, magnesium salts and the like. Other pharmaceutically acceptable salts include (where appropriate) non-toxic ammonium, quaternary ammonium and amine cations formed using counter ions (e.g., halide, hydroxide, carboxylate, sulfate, phosphate, nitrate, lower alkyl sulfonate and aryl sulfonate).
[0046] As used herein, the phrase "incretin mimetics" includes, but is not limited to, GLP-1 peptides, GLP-1 receptor agonists, peptide derivatives of GLP-1, peptide analogs of GLP-1; exenatide, exenatide having the amino acid sequence of SEQ ID NO: 307, exenatide peptides, peptide derivatives of exenatide, and peptide analogs of exenatide. Examples of preferred incretin mimetics include exenatide, exenatide having the amino acid sequence of exendin-4 (a naturally occurring form of exenatide), exenatide-LAR, lixisenatide, GLP-1 (7-36), liraglutide, semaglutide, dulaglutide, albiglutide, and taspoglutide. Incretin mimetics are also referred to herein as "insulinotropic peptides." Incretin mimetics that target the GLP-1 receptor are also referred to in the literature as "GLP-1 receptor agonists" or "GLP-1 agonists," where both terms are used interchangeably herein.
[0047] The term "exenatide" as used herein includes, but is not limited to, exenatide, exenatide having the amino acid sequence of (HGEGTFTSDLSKQMEEEAVRLFIEWLKNGGPSSGAPPPS-NH2), SEQ ID NO: 307, natural incretin analog-4, exenatide peptide, exenatide peptide analogs, and exenatide peptide derivatives.
[0048] The term "GLP-1" refers to a polypeptide produced by L cells located primarily in the ileum and colon, and to a lesser extent in the duodenum and jejunum. GLP-1 is a regulatory peptide that binds to the extracellular region of the GLP-1 receptor (GLP-1R), a G-coupled protein receptor on beta cells, and stimulates the insulin response to nutrients absorbed from the intestine via adenylate cyclase activity and cAMP production [Baggio 2007, "Biology of incretins: GLP-1 and GIP", Gastroenterology, Vol. 132(6): 2131-57; Holst 2008, "The incretin system and its role in type 2 diabetes mellitus", Mol Cell Endocrinology, Vol. 297(1-2): 127-36]. The effects of GLP-1R agonism are multiple. GLP-1 maintains glucose homeostasis by enhancing endogenous glucose-dependent insulin secretion, rendering beta cells glucose competent and sensitive to GLP-1, inhibiting glucagon release, restoring first and second phase insulin secretion, slowing gastric emptying, reducing food intake, and improving satiety [Holst 2008 Mol. Cell Endocrinology; Kjems 2003 “The influence of GLP-1 on glucose-stimulated insulin secretion: effects on beta-cell sensitivity in type 2 and nondiabetic subjects”, Diabetes, 52(2): 380-86; Holst 2013 “Incretin hormones and the satiation signal”, Int J Obes (Lond), 37(9): 1161-69; Seufert 2014, “The extra-pancreatic effects of GLP-1 receptor agonists: a focus on the cardiovascular, gastrointestinal and central nervous systems”, Diabetes Obes Metab, Vol. 16(8):673-88]. Given the mode of action of GLP-1, the risk of hypoglycemia is minimal.
[0049] As described in more detail below, in some embodiments, the amylin analog polypeptides disclosed herein are provided as an adjunct to insulin therapy in methods for treating type 1 diabetes. As used herein, the term "insulin" refers to human insulin or any insulin analog. Exemplary non-limiting insulin analogs include those listed in Table 2:

[0051]
[0052]
[0053]
[0054] As used herein, the term "mealtime insulin" refers to a rapid-acting insulin formulation that reaches peak blood concentrations within about 45-90 minutes after administration and peak activity within about 1 to 3 hours, and is administered at or around mealtime.
[0055] As used herein, the term "vehicle" refers to a medium for carrying a compound, such as a drug or particles containing a drug. The vehicles of the present invention typically include components such as a polymer and a solvent. The suspension vehicles of the present invention typically include a solvent and a polymer for preparing a suspension formulation that also includes a drug particle formulation.
[0056] As used herein, the phrase "phase separation" refers to the formation of multiple phases (e.g., a liquid phase and a gel phase) in a suspension vehicle, for example, when the suspension vehicle contacts an aqueous environment. In some embodiments of the present invention, the suspension vehicle is formulated to exhibit phase separation upon contact with an aqueous environment having less than about 10% water.
[0057] As used herein, the phrase "single phase" refers to a solid, semisolid, or liquid homogeneous system that is physically and chemically uniform throughout.
[0058] As used herein, the term "disperse" refers to dissolving, dispersing, suspending, or otherwise distributing a compound, such as a drug particle formulation, in a suspension vehicle.
[0059] As used herein, the phrase "chemically stable" refers to formulations that produce an acceptable percentage of degradation products over a defined period of time by chemical pathways such as deamidation (usually by hydrolysis), aggregation, or oxidation.
[0060] As used herein, the phrase "physically stable" refers to a formulation that forms an acceptable percentage of aggregates (e.g., dimers and other higher molecular weight products). Additionally, a physically stable formulation does not change its physical state, e.g., from liquid to solid or from amorphous to crystalline form.
[0061] The term "viscosity" as used herein generally refers to a value determined from the ratio of shear stress to shear rate (see, e.g., Considine, DM and Considine, GD, Encyclopedia of Chemistry, 4th ed., Van Nostrand, Reinhold, NY, 1984), essentially as follows:
[0062] F / A = μ*V / L (Equation 1)
[0063] Where F / A = shear stress (force per unit area),
[0064] μ = proportionality constant (viscosity), and
[0065] V / L = velocity per layer thickness (shear rate).
[0066] In some embodiments, the viscosity of the suspension medium of the present invention is determined by the ratio of shear stress to shear rate. The measurement of shear stress and shear rate is usually determined using the parallel plate rheology carried out under selected conditions (such as a temperature of about 37°C). Other methods for determining viscosity include using a viscometer such as a Cannon-Fenske viscometer, a Ubbelohde viscometer (Ubbelohdeviscometer) (for Cannon-Fenske opaque solutions) or an Ostwald viscometer to measure kinematic viscosity. In general, the suspension medium of the present invention has the viscosity that is enough to prevent the particle preparation suspended therein from sedimenting during storage and in a delivery method such as in an implantable drug delivery device.
[0067] As used herein, the term "non-aqueous" refers to, for example, a total moisture content of a suspension formulation that is typically less than or equal to about 10 wt %, such as less than or equal to about 7 wt %, less than or equal to about 5 wt % and / or less than about 4 wt %. In addition, the particle formulations of the present invention contain less than about 10 wt %, such as less than about 5 wt % residual moisture.
[0068] As used herein, the term "subject" refers to any member of the subphylum Chordata, including but not limited to humans and other primates, including non-human primates such as rhesus macaques and other monkey species and chimpanzees and other ape species; livestock such as cattle, sheep, pigs, goats, and horses; domesticated mammals such as dogs and cats; laboratory animals including rodents such as mice, rats, and guinea pigs; birds including domesticated, wild, and game birds such as chickens, turkeys, and other quail, ducks, geese, and the like. The term does not indicate a specific age or sex. Thus, it is intended to encompass both adult and newborn individuals.
[0069] As used herein, the terms "treatment," "treat," and "treating" refer to reversing, alleviating, delaying the onset of, or inhibiting the progression of a disease or condition as described herein, or one or more symptoms thereof. In some embodiments, treatment may be administered after one or more symptoms have appeared. In other embodiments, treatment may be administered when symptoms are not present. For example, treatment may be administered to a susceptible individual before the onset of symptoms (e.g., based on a history of symptoms and / or based on genetic or other susceptibility factors). Treatment may also be continued after symptoms have resolved, for example, to prevent or delay their recurrence.
[0070] The term "osmotic delivery device" as used herein generally refers to a device for delivering a drug (e.g., a disclosed amylin analog polypeptide) to a subject, wherein the device includes, for example, a reservoir (e.g., made of a titanium alloy) having an inner cavity containing a suspension formulation comprising a drug (e.g., a disclosed amylin analog polypeptide) and an osmotic agent formulation. A piston assembly disposed in the inner cavity separates the suspension formulation from the osmotic agent formulation. A semipermeable membrane is disposed at a first distal end of the reservoir adjacent to the osmotic agent formulation, and a diffusion regulator (which defines a delivery orifice through which the suspension formulation exits the device) is disposed at a second distal end of the reservoir adjacent to the suspension formulation. Typically, the osmotic delivery device is implanted within a subject, e.g., subdermally or subcutaneously (e.g., in the inner, outer, or posterior portion of the upper arm and in the abdominal region). An exemplary osmotic delivery device is (ALZA Corporation, Mountain View, Calif.) delivery device. Examples of synonymous terms with "osmotic delivery device" include, but are not limited to, "osmotic drug delivery device," "osmotic drug delivery system," "osmotic device," "osmotic delivery device," "osmotic delivery system," "osmotic pump," "implantable drug delivery device," "drug delivery system," "drug delivery device," "implantable osmotic pump," "implantable drug delivery system," and "implantable delivery system." Other terms for "osmotic delivery device" are known in the art.
[0071] As used herein, the term "continuous delivery" generally refers to the substantially continuous release of a drug from an osmotic delivery device and entry into tissues near the implant site, such as the subdermal and subcutaneous tissues. For example, an osmotic delivery device releases a drug substantially at a predetermined rate based on the principle of osmosis. Extracellular fluid enters the osmotic delivery device through a semipermeable membrane and directly into an osmotic engine, which expands to drive a piston at a slow and consistent rate of travel. The movement of the piston causes the drug formulation to be released through the orifice of a diffusion regulator. Therefore, the release of the drug from the osmotic delivery device is at a slow, controlled, consistent rate.
[0072] As used herein, the term "substantially steady-state delivery" generally refers to the delivery of a drug at or near a target concentration over a defined period of time, wherein the amount of drug delivered from an osmotic delivery device is substantially zero-order. Substantially zero-order delivery of an active agent (e.g., a disclosed amylin analog polypeptide) means that the rate of drug delivery is constant and independent of the drug available in the delivery system; for example, for zero-order delivery, if the drug delivery rate is plotted against time and a line is fit to the data, the line has a slope of about zero, as determined by standard methods (e.g., linear regression).
[0073] As used herein, the phrase "drug half-life" refers to the time it takes for a drug to eliminate half of its concentration from the plasma. When a drug is administered via injection or intravenously, the half-life of a drug is typically measured by monitoring how the drug degrades. Drugs are typically detected using, for example, radioimmunoassays (RIA), chromatographic methods, electrochemiluminescence (ECL) assays, enzyme-linked immunosorbent assays (ELISAs), or immunoenzymatic sandwich assays (IEMAs).
[0074] The terms "μg" and "mcg" and "ug" are to be understood to mean "microgram." Similarly, the terms "μl" and "uL" are to be understood to mean "microliter," and the terms "μM" and "uM" are to be understood to mean "micromolar."
[0075] The term "serum" is intended to refer to any blood product in which a substance can be detected. Thus, the term serum includes at least whole blood, serum, and plasma. For example, "the amount of [substance] in a subject's serum" would encompass "the amount of [substance] in a subject's plasma."
[0076] Baseline was defined as the last assessment on the day of initial placement of the osmotic delivery device (containing drug or placebo) or the day before.
[0077] 3. Endogenous amylin, related peptides, and amylin receptors
[0078] Human amylin (a 37-residue polypeptide hormone) is co-secreted with insulin from pancreatic beta cells. Loss of beta cell function, which occurs early in type 1 diabetes and may occur late in type 2 diabetes, leads to insufficient secretion of both insulin and amylin. Amylin is thought to play a role in blood glucose regulation by slowing gastric emptying and promoting satiety, thereby preventing post-meal spikes in blood glucose levels. The overall effect is to slow the rate at which glucose appears in the blood after a meal.
[0079] The amino acid sequence of amylin is most closely related to that of calcitonin gene-related peptide (CGRP). CGRP also shares similarly positioned disulfide bonds and an amidated C-terminus. This is also true for calcitonin, adrenomedullin, and adrenomedullin 2. Collectively, these peptides form a small family united by these characteristic features. Consequently, there is some overlap in the cognate receptors bound by each peptide and in their pharmacological activities. Figure 1 The table illustrates a comparative sequence alignment of amylin and certain related reference polypeptides.
[0080] Peptides commonly referred to as members of the calcitonin (CT) peptide family include calcitonin gene-related peptide (CGRP), calcitonin (CT), amylin (AMY), adrenomedullin 1, and adrenomedullin 2 / mesotropin (ADM1, ADM2, respectively). Two G protein-coupled receptor proteins (calcitonin receptor; CTR, and calcitonin receptor-like receptor; CALCRL) and three receptor activity-modifying proteins (RAMP1, RAMP2, RAMP3) constitute the pharmacologically distinct receptors of the entire peptide family (CTR, AMY1, AMY2, AMY3, CGRPR, AM1, AM2). There appear to be at least five different receptors (AMY1, AMY2, AMY3, CTR, CGRPR) to which amylin binds with significant affinity. CTR dimerizes with RAMP 1, 2, or 3 to reconstitute AMY1, AMY2, or AMY3 receptors that are pharmacologically selective for amylin relative to calcitonin. In the absence of RAMPs, CTR pharmacology becomes selective for calcitonin relative to amylin. Dimerization of CALCRL with RAMP1 generates CGRPR with high affinity for CGRP and reduced affinity for all other peptide family members, including amylin. CALCRL and RAMP2 or RAMP3 reconstitute the pharmacology of AM1 and AM2, respectively, with very low to no affinity for amylin.
[0081] Amylin analog polypeptides with binding affinity for the amylin receptor complex have been developed. For example, pramlintide was developed by Amylin Pharmaceuticals and approved by the U.S. Food and Drug Administration (FDA) as a synthetic analog of human amylin for treating patients with type 1 and type 2 diabetes who use mealtime insulin but, despite optimal insulin therapy, are unable to achieve desired glycemic control. Pramlintide is an amylin mimetic that is at least as effective as human amylin. It is also a 37-amino acid polypeptide and differs from the amino acid sequence of human amylin in the amino acid substitution of proline at positions 25 (alanine), 28 (serine), and 29 (serine). Due to these substitutions, pramlintide is soluble, non-adhesive, and non-aggregating, thereby overcoming the various physicochemical tendencies of natural human amylin. The half-life of pramlintide in humans is approximately 48 minutes, which is longer than natural human amylin (approximately 13 minutes). Pramlintide requires frequent and inconvenient administration.
[0082] For the treatment of patients with type 1 diabetes, pramlintide is administered up to four times daily via subcutaneous injection in the thigh or abdomen before meals as an adjunct to insulin therapy administered after meals. Pramlintide cannot be mixed with insulin; a separate syringe is used. Pramlintide is administered with or before each meal or snack consisting of at least 250 calories or 30 grams of carbohydrates. The typical starting dose for patients with type 1 diabetes is 15 μg of subcutaneous pramlintide before each meal, subsequently titrated to a target dose of 60 μg before each meal. Reported side effects of pramlintide include nausea and vomiting. Particularly for patients with type 1 diabetes, adverse reactions can include severe hypoglycemia. Therefore, for diabetic patients starting pramlintide, the dose of mealtime insulin is reduced.
[0083] For the treatment of patients with type 2 diabetes, pramlintide is administered via subcutaneous injection at a recommended starting dose of 60 μg, with a target maintenance dose of 120 μg before each meal.
[0084] Davalintide (AC2307) is another analog of human amylin. Davalintide is an investigational compound with a half-life of approximately 26 minutes. Similar to pramlintide, davalintide will similarly require frequent administration via injection.
[0085] Certain disclosed amylin analog polypeptides, including those in Table 3 below, exhibit one or more of the following: superior solubility, stability, biological activity, and specificity, and a longer half-life compared to endogenous human amylin and known synthetic amylin analog polypeptides. Certain disclosed amylin analog polypeptides are developed to accommodate less frequent administration than required for pramlintide. Certain disclosed amylin analog polypeptides are developed for administration via weekly or monthly injections. Certain disclosed amylin analog polypeptides are developed for administration via implantation of a delivery device comprising the amylin analog polypeptide, wherein the delivery device comprises a dosage of the amylin analog polypeptide for up to 3 months, 6 months, 9 months, one year, 18 months, or two years.

[0458] 5. Conjugation of a lipophilic substituent to either peptide, optionally via a spacer
[0459] In some embodiments, any one of the disclosed polypeptides is each optionally substituted with one or more lipophilic substituents via a spacer, wherein "lipophilic substituent" and "spacer" are defined herein. In some embodiments, any one of the disclosed polypeptides (comprising an amino acid sequence selected from the group consisting of the amino acid sequence represented by any one of the common sequences of SEQ ID NO: 1 to SEQ ID NO: 143) each optionally comprises one or more lipophilic substituents via a spacer, or can be modified or further modified by each optionally covalently linking one or more lipophilic substituents via a spacer. In some embodiments, the lipophilic substituent can be linked to an amino group of the polypeptide (e.g., the ε-amino group of a lysine residue) by means of a carboxyl group of the lipophilic substituent or, optionally, an amino group of the spacer, wherein the carboxyl group of the spacer forms an amide bond with the ε-amino group of the lysine residue.
[0460] Lipophilic substituents
[0461] Each optionally via a "spacer", one or more "lipophilic substituents" are conjugated to any of the disclosed polypeptides of the present invention in order to prolong the effect of the polypeptide by promoting binding to serum albumin and delaying the renal clearance of the conjugated polypeptide. As used herein, "lipophilic substituents" include: substituents comprising 4 to 40 carbon atoms, 8 to 25 carbon atoms, 12 to 22 carbon atoms, or 6 to 20 carbon atoms. The lipophilic substituent can be linked to an amino group of the polypeptide (e.g., the ε-amino group of a lysine residue) via a carboxyl group of the lipophilic substituent or, optionally, an amino group of a spacer, which in turn forms an amide bond with the amino group of the amino acid (e.g., lysine) residue to which it is attached. In some embodiments, the polypeptide comprises three, two, or preferably one lipophilic substituent, each with or without an optional spacer, as defined in more detail below.
[0462] In some embodiments, the lipophilic substituent comprises a straight or branched alkyl group. In some embodiments, the lipophilic substituent is an acyl group of a straight or branched fatty acid. In some embodiments, the lipophilic substituent is an acyl group of a straight or branched fatty acid further substituted with one or more carboxylic acid and / or hydroxamic acid groups.
[0463] In some embodiments, the polypeptide comprises three, two, or preferably one lipophilic substituent, each without an optional spacer. In some embodiments, the lipophilic substituent is a monovalent group of formula I:
[0464] -CO-(CH2) m -Z
[0465] Formula I
[0466] in
[0467] Z is -CH3 or -CO2H; and
[0468] m is 4 to 24,
[0469] The lipophilic substituent forms an amide bond between an amino group of the disclosed polypeptide (eg, the epsilon-amino group of lysine) and the CO-group of the lipophilic substituent.
[0470] In some embodiments, m is selected from the group consisting of 4-20, 8-20, 12-20, 14-20, 16-20, 14, 16, 18, and 20.
[0471] In some embodiments, Z is -CO2H and the lipophilic substituent has the formula -CO-(CH2) m -CO2H. In some embodiments, -CO-(CH2) m-Z is selected from the group consisting of: -CO-(CH2)4-CO2H, -CO-(CH2)5-CO2H, -CO-(CH2)6-CO2H, -CO-(CH2)7-CO2H, -CO-(CH2)8-CO2H, -CO-(CH2)9-CO2H, -CO-(CH2) 10 -CO2H, -CO-(CH2) 11 -CO2H, -CO-(CH2) 12 -CO2H, -CO-(CH2) 13 -CO2H, -CO-(CH2) 14 -CO2H, -CO-(CH2) 15 -CO2H, -CO-(CH2) 16 -CO2H, -CO-(CH2) 17 -CO2H, -CO-(CH2) 18 -CO2H, -CO-(CH2) 19 -CO2H, -CO-(CH2) 20 -CO2H.
[0472] In some embodiments, the lipophilic substituent is -CO-(CH2) 18 -CO2H.
[0473] In some embodiments, Z is -CH3, and the lipophilic substituent has the formula -CO-(CH2) m -CH3.

[0930] GLP-1, including three forms of the peptide, GLP-1 (1-37), GLP-1 (7-37), and GLP-1 (7-36) amide, as well as peptide analogs of GLP-1, have been shown to stimulate insulin secretion (i.e., to be insulinotropic), which induces glucose uptake into cells and leads to a decrease in serum glucose concentration (see, e.g., Mojsov, S., Int. J. Peptide Protein Research, 40:333-343 (1992)).
[0931] Numerous GLP-1 receptor agonists (e.g., GLP-1 peptide derivatives and peptide analogs) that exhibit insulinotropic effects are known in the art (see, e.g., U.S. Patent Nos. 5,118,666; 5,120,712; 5,512,549; 5,545,618; 5,574,008; 5,574,008; 5,614,492; 5,958,909; 6,191,102; 6,268,343; 6,329,336; 6,451,974; 6,458,924; 6,514,500; 6,593, 295; 6,703,359; 6,706,689; 6,720,407; 6,821,949; 6,849,708; 6,849,714; 6,887,470; 6,887,849; 6,903,186; 7,022,674; 7,041,646; 7,084,243; 7,101,843; 7,138,486; 7,141,547; 7,144,863; and 7,199,217) and in clinical trials (e.g., tasirolid and albiglutide). An example of a GLP-1 receptor agonist in the practice of the present invention is (Novo Nordisk A / S, Bagsvaerd DK) (liraglutide; U.S. Patent Nos. 6,268,343, 6,458,924, and 7,235,627). Once-daily injectable (liraglutide) is commercially available in the United States, Europe and Japan. Another example of a GLP-1 receptor agonist is (Novo Nordisk A / S, Bagsvaerd DK) (semaglutide). For ease of reference herein, the family of GLP-1 receptor agonists, GLP-1 peptides, GLP-1 peptide derivatives, and GLP-1 peptide analogs having insulinotropic activity are collectively referred to as "GLP-1."
[0932] The molecule exenatide has the amino acid sequence of incretin analog-4 (Kolterman OG et al., J. Clin. Endocrinol. Metab. 88(7):3082-9 (2003)) and is produced by chemical synthesis or recombinant expression. For ease of reference herein, the family of exenatide peptides (e.g., including incretin analog-3, incretin analog-4, and incretin analog-4-amide), exenatide peptide derivatives, and exenatide peptide analogs are collectively referred to as "exenatide."
[0933] Peptide YY (PYY) is a 36 amino acid residue peptide amide. PYY inhibits intestinal motility and blood flow (Laburthe, M., Trends Endocrinol Metab. 1(3): 168-74 (1990), regulates intestinal secretion (Cox, HM et al., Br J Pharmacol 101(2): 247-52 (1990); Playford, RJ et al., Lancet 335(8705): 1555-7 (1990)), and stimulates net absorption (MacFayden, RJ et al., Neuropeptides 7(3): 219-27 (1986)). Two major in vivo variants, PYY(1-36) and PYY(3-36), have been identified (e.g., Eberlein, GA et al., Peptides 10(4), 797-803 (1989). The sequences of PYY and its peptide analogs and peptide derivatives are known in the art (eg, US Pat. Nos. 5,574,010 and 5,552,520).
[0934] Oxyntomodulin is a naturally occurring 37-amino acid peptide hormone found in the colon that has been found to suppress appetite and promote weight loss (Wynne K et al., Int J Obes (Lond) 30(12):1729-36 (2006)). The sequences of oxyntomodulin and its peptide analogs and peptide derivatives are known in the art (e.g., Bataille D et al., Peptides 2(Suppl 2):41-44 (1981); and U.S. Patent Publication Nos. 2005 / 0070469 and 2006 / 0094652).
[0935] Gastric inhibitory peptide (GIP) is an insulinotropic peptide hormone (Efendic, S. et al., Horm Metab Res. 36: 742-6 (2004)) and is secreted by the mucosa of the duodenum and jejunum in response to absorbed fats and carbohydrates that stimulate the pancreas to secrete insulin. GIP circulates as a biologically active 42 amino acid peptide. GIP is also known as glucose-dependent insulinotropic protein. GIP is a 42 amino acid gastrointestinal regulatory peptide that stimulates insulin secretion from pancreatic beta cells in the presence of glucose (Tseng, C. et al., PNAS 90: 1992-1996 (1993)). The sequences of GIP and its peptide analogs and peptide derivatives are known in the art (e.g., Meier JJ, Diabetes Metab Res Rev. 21 (2): 91-117 (2005) and Efendic S., Horm Metab Res. 36 (11-12): 742-6 (2004)).
[0936] Glucagon is a peptide hormone produced by the alpha cells of the pancreas that increases glucose concentration in the bloodstream. Its action is opposite to that of insulin, which lowers glucose concentration. When blood glucose concentrations are too low, the pancreas releases glucagon. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High blood glucose levels stimulate the release of insulin. Insulin allows insulin-dependent tissues to take up and use glucose. Thus, glucagon and insulin are part of a feedback system that keeps blood glucose levels stable.

[0966] The particles are typically sized so that they can be delivered via an implantable osmotic delivery device. The uniform shape and size of the particles typically contribute to providing a consistent and uniform release rate from such a delivery device; however, particle preparations with an abnormal particle size distribution profile may also be used. For example, in a typical implantable osmotic delivery device with a delivery orifice, the size of the particles is about 30% smaller than the delivery orifice diameter, more preferably about 20% smaller, more preferably about 10% smaller. In one embodiment of a particle preparation for an osmotic delivery system, wherein the delivery orifice diameter of the implant is about 0.5 mm, the particle size may be, for example, less than about 150 microns to about 50 microns. In one embodiment of a particle preparation for an osmotic delivery system, wherein the delivery orifice diameter of the implant is about 0.1 mm, the particle size may be, for example, less than about 30 microns to about 10 microns. In one embodiment, the orifice is about 0.25 mm (250 microns) and the particle size is about 2 microns to about 5 microns.
[0967] Those skilled in the art will appreciate that particle populations follow the principles of particle size distribution. Widely used, art-recognized methods for describing particle size distribution include, for example, mean diameter and D values, such as D50 values, which are commonly used to represent the mean diameter of a range of particle sizes for a given sample.
[0968] The particles of the particle formulation have a diameter between about 2 microns and about 150 microns, such as less than 150 microns in diameter, less than 100 microns in diameter, less than 50 microns in diameter, less than 30 microns in diameter, less than 10 microns in diameter, less than 5 microns in diameter, and about 2 microns in diameter. Preferably, the particles have a diameter between about 2 microns and about 50 microns.
[0969] The particles of the particle formulation comprising the isolated amylin analog polypeptide have an average diameter between about 0.3 microns and about 150 microns. The particles of the particle formulation comprising the isolated amylin analog polypeptide have an average diameter between about 2 microns and about 150 microns, for example, an average diameter less than 150 microns, an average diameter less than 100 microns, an average diameter less than 50 microns, an average diameter less than 30 microns, an average diameter less than 10 microns, an average diameter less than 5 microns, and an average diameter of about 2 microns. In some embodiments, the particles have an average diameter between about 0.3 microns and 50 microns, for example, between about 2 microns and about 50 microns. In some embodiments, the particles have an average diameter between 0.3 microns and 50 microns, for example, between about 2 microns and about 50 microns, wherein each particle has a diameter of less than about 50 microns.
[0970] Typically, when incorporated into a suspension vehicle, at the delivery temperature, the particles of the particle formulation will not settle in less than about 3 months, preferably will not settle in less than about 6 months, more preferably will not settle in less than about 12 months, more preferably will not settle in less than about 24 months, and most preferably will not settle in less than about 36 months at the delivery temperature. The suspension vehicle typically has a viscosity of about 5,000 to about 30,000 poise, preferably about 8,000 to about 25,000 poise, more preferably about 10,000 to about 20,000 poise. In one embodiment, the suspension vehicle has a viscosity of about 15,000 poise ± about 3,000 poise. In general, smaller particles tend to have a lower sedimentation rate in a viscous suspension vehicle than larger particles. Therefore, micron to nanometer sized particles are generally required. In viscous suspension formulations, based on simulation modeling studies, particles of about 2 microns to about 7 microns of the present invention will not settle for at least 20 years at room temperature. In one embodiment of the particle formulation of the present invention for use in an implantable osmotic delivery device, particles having a size less than about 50 microns, more preferably less than about 10 microns, and more preferably in the range of about 2 microns to about 7 microns are included.
[0971] In summary, the disclosed polypeptides or pharmaceutically acceptable salts thereof are formulated into dry powders in the form of solid particles that retain maximum chemical and biological stability of the drug. The particles provide long-term storage stability at high temperatures and thus allow for the delivery of stable and biologically effective drugs to subjects for extended periods of time. The particles are suspended in a suspension vehicle for administration to a patient.
[0972] Particle suspension in vehicle
[0973] In one aspect, the suspension vehicle provides a stable environment in which the drug particle formulation is dispersed. The drug particle formulation is chemically and physically stable in the suspension vehicle (as described above). The suspension vehicle typically comprises one or more polymers and one or more solvents that form a solution having a viscosity sufficient to uniformly suspend the drug-containing particles. The suspension vehicle may comprise other components, including but not limited to surfactants, antioxidants, and / or other compounds soluble in the vehicle.
[0974] The viscosity of the suspension vehicle is generally sufficient to prevent sedimentation of the drug particle formulation during storage and use in a delivery method, such as an implantable osmotic delivery device. The suspension vehicle is biodegradable because the suspension vehicle disintegrates or breaks down over a period of time in response to the biological environment while the drug particles dissolve in the biological environment and absorb the active pharmaceutical ingredient (i.e., drug) in the particles.
[0975] In embodiments, the suspension vehicle is a "single-phase" suspension vehicle, which is a solid, semisolid, or liquid homogeneous system that is physically and chemically uniform throughout.
[0976] The solvent in which the polymer is dissolved can affect the characteristics of the suspension formulation, such as the behavior of the drug particle formulation during storage. The solvent can be selected in combination with the polymer so that the resulting suspension vehicle exhibits phase separation upon contact with an aqueous environment. In some embodiments of the present invention, the solvent can be selected in combination with the polymer so that the resulting suspension vehicle exhibits phase separation upon contact with an aqueous environment having less than approximately 10% water.
[0977] The solvent may be an acceptable solvent that is not miscible with water. The solvent may also be selected so that the polymer is soluble in the solvent at high concentrations, for example, at a polymer concentration greater than about 30%. Examples of solvents that can be used in the practice of the present invention include, but are not limited to, lauryl alcohol, benzyl benzoate, benzyl alcohol, lauryl lactate, decanol (also known as decyl alcohol), ethyl hexyl lactate, and long-chain (C8 to C24) aliphatic alcohols, esters, or mixtures thereof. The solvent used in the suspension vehicle may be "dry" in that it has a low moisture content. Preferred solvents for preparing the suspension vehicle include lauryl lactate, lauryl alcohol, benzyl benzoate, and mixtures thereof.
[0978] Examples of polymers for preparing suspension vehicles of the present invention include, but are not limited to, polyesters (e.g., polylactic acid and polylactic polyglycolic acid), pyrrolidone-containing polymers (e.g., polyvinyl pyrrolidone having a molecular weight in the range of about 2,000 to about 1,000,000), esters or ethers of unsaturated alcohols (e.g., vinyl acetate), polyoxyethylene polyoxypropylene block copolymers, or mixtures thereof. Polyvinyl pyrrolidone can be characterized by its K value (e.g., K-17), which is a viscosity index. In one embodiment, the polymer is a polyvinyl pyrrolidone having a molecular weight of 2,000 to 1,000,000. In a preferred embodiment, the polymer is polyvinyl pyrrolidone K-17 (typically having an approximate average molecular weight range of 7,900-10,800). The polymer used in the suspension vehicle may include one or more different polymers or may include different grades of a single polymer. The polymer used in the suspension vehicle may also be dry or have a low moisture content.
[0979] In general, the composition of the suspension vehicle used in the present invention can vary based on the desired performance characteristics. In one embodiment, the suspension vehicle can comprise from about 40 wt% to about 80 wt% polymer and from about 20 wt% to about 60 wt% solvent. Preferred embodiments of the suspension vehicle include vehicles formed from polymer and solvent combined in the following ratios: about 25 wt% solvent and about 75 wt% polymer; about 50 wt% solvent and about 50 wt% polymer; about 75 wt% solvent and about 25 wt% polymer. Thus, in some embodiments, the suspension vehicle can comprise, and in other embodiments consist essentially of, the selected components.
[0980] Suspension vehicles can exhibit Newtonian behavior. Suspension vehicles are typically formulated to provide a viscosity that maintains a uniform dispersion of particle preparations for a predetermined time period. This helps facilitate the adjustment of suspension formulations to provide controlled delivery of the drug contained in the pharmaceutical particle preparation. The viscosity of the suspension vehicle can vary depending on the desired application, the size and type of particle preparation, and the loading of the particle preparation in the suspension vehicle. The viscosity of the suspension vehicle can be varied by changing the type or relative amount of the solvent or polymer used.
[0981] The suspension vehicle may have a viscosity ranging from about 100 poise to about 1,000,000 poise, preferably from about 1,000 poise to about 100,000 poise. In a preferred embodiment, the suspension vehicle typically has a viscosity of between about 5,000 and about 30,000 poise at 33°C, preferably between about 8,000 and about 25,000 poise, and more preferably between about 10,000 and about 20,000 poise. In one embodiment, the suspension vehicle has a viscosity of about 15,000 poise ± about 3,000 poise at 33°C. Viscosity can be measured using a parallel plate rheometer at a shear rate of 10-4 / sec at 33°C.
[0982] When in contact with an aqueous environment, the suspension vehicle may exhibit phase separation; however, typically the suspension vehicle exhibits substantially no phase separation as a function of temperature. For example, at temperatures in the range of about 0°C to about 70°C and after temperature cycling, e.g., from 4°C to 37°C to 4°C, the suspension vehicle typically exhibits no phase separation.
[0983] Suspension vehicles can be prepared by combining polymers and solvents under dry conditions, for example, in a drying oven. Polymers and solvents can be combined at high temperatures, for example, at about 40°C to about 70°C, and liquefied and formed into a single phase. The ingredients can be blended under vacuum to remove the bubbles produced by the dry ingredients. Conventional mixers, such as double helical blades or similar mixers, set at a speed of about 40rpm can be used to combine the ingredients. However, higher speeds can also be used to mix the ingredients. Once a liquid solution of the ingredients is obtained, the suspension vehicle can be cooled to room temperature. Differential scanning calorimetry (DSC) can be used to verify that the suspension vehicle is a single phase. In addition, the components of the vehicle (such as solvents and / or polymers) can be processed to substantially reduce or substantially remove peroxides (such as by treating with methionine; referring to, for example, U.S. Patent Application Publication No. 2007-0027105).
[0984] The drug particle formulation is added to the suspension vehicle to form a suspension formulation. In some embodiments, the suspension formulation may comprise, and in other embodiments consist essentially of, the drug particle formulation and the suspension vehicle.
[0985] Suspension preparations can be prepared by dispersing the particle preparations in a suspension vehicle. The suspension vehicle can be heated and the particle preparations can be added to the suspension vehicle under dry conditions. The ingredients can be mixed under vacuum at high temperatures, for example, at about 40°C to about 70°C. The ingredients can be mixed at a sufficient speed, for example, at about 40rpm to about 120rpm, and for a sufficient amount of time, for example, about 15 minutes, to obtain a uniform dispersion of the particle preparations in the suspension vehicle. The mixer can be a double helical blade or other suitable mixer. The resulting mixture can be removed from the mixer, sealed in a dry container to prevent water from contaminating the suspension preparation, and cooled to room temperature before further use, for example, being loaded into an implantable drug delivery device, a unit dose container, or a multidose container.
[0986] Suspension formulations typically have a total moisture content of less than about 10 wt%, preferably less than about 5 wt%, and more preferably less than about 4 wt%.
[0987] In preferred embodiments, the suspension formulations of the present invention are substantially homogeneous and flowable to provide for delivery of the drug particle formulation from an osmotic delivery device to a subject.
[0988] In summary, the components of the suspension vehicle provide biocompatibility. The components of the suspension vehicle provide suitable chemical and physical properties to form a stable suspension of the drug particle formulation. These properties include (but are not limited to) the following: viscosity of the suspension; purity of the vehicle; residual moisture of the vehicle; density of the vehicle; compatibility with dry powders; compatibility with implantable devices; molecular weight of the polymer; stability of the vehicle; and hydrophobicity and hydrophilicity of the vehicle. These properties can be manipulated and controlled, for example, by varying the vehicle composition and manipulating the ratios of the components used in the suspension vehicle.
[0989] Suspension formulations described herein can be used in implantable osmotic delivery devices to provide zero-order, continuous, controlled and sustained delivery of a compound over an extended period of time, such as over several weeks, several months, or up to about a year or longer. Such implantable osmotic delivery devices are typically capable of delivering a suspension formulation comprising a drug at a desired flow rate over a desired time period. Suspension formulations can be loaded into an implantable osmotic delivery device by conventional techniques.
[0990] Implantable delivery
[0991] The dose and delivery rate can be selected to achieve a desired blood concentration of the drug, generally within less than about 6 half-lives of the drug in the subject following implantation of the device. The blood concentration of the drug is selected to obtain the optimal therapeutic effect of the drug while avoiding undesirable side effects that may be induced by excessive concentrations of the drug, while at the same time avoiding peaks and troughs that may induce side effects associated with peak or trough plasma concentrations of the drug.
[0992] An implantable osmotic delivery device generally includes a reservoir having at least one orifice through which a suspension formulation is delivered. The suspension formulation can be stored within the reservoir. In a preferred embodiment, the implantable drug delivery device is an osmotic delivery device, wherein drug delivery is driven by osmosis. Some osmotic delivery devices and their components have been described, for example delivery device or similar device (see, e.g., U.S. Pat. Nos. 5,609,885; 5,728,396; 5,985,305; 5,997,527; 6,113,938; 6,132,420; 6,156,331; 6,217,906; 6,261,584; 6,270,787; 6,287,295; 6,375,978; 6,395,292; 6,508,808; 6,544, 252; 6,635,268; 6,682,522; 6,923,800; 6,939,556; 6,976,981; 6,997,922; 7,014,636; 7,207,982; and 7,112,335; 7,163,688; U.S. Patent Publication Nos. 2005 / 0175701, 2007 / 0281024, 2008 / 0091176, and 2009 / 0202608).
[0993] Osmotic delivery devices typically consist of a cylindrical reservoir containing an osmotic engine, a piston, and a drug formulation. The reservoir is capped at one end by a rate-controlled semipermeable membrane and at the other end by a diffusion regulator that releases a suspension formulation containing the drug from the drug reservoir. The piston separates the drug formulation from the osmotic engine and utilizes a seal to prevent water in the osmotic engine chamber from entering the drug reservoir. The diffusion regulator is designed to be combined with the drug formulation to prevent body fluids from entering the drug reservoir through the orifice.
[0994] Osmotic devices release drugs at a predetermined rate based on the principle of osmosis. Extracellular fluid enters the osmotic delivery device through a semipermeable membrane and directly enters a salt engine that can swell and drive a piston at a slow and steady delivery rate. The piston motion causes the drug formulation to be released or leave the orifice at a predetermined shear rate. In one embodiment of the invention, the reservoir of the osmotic device is loaded with a suspension formulation, wherein the device can deliver a suspension formulation to the subject at a predetermined therapeutically effective delivery rate over a prolonged period of time (e.g., about 1, about 3, about 6, about 9, about 10, and about 12 months).
[0995] The rate of release of the drug from an osmotic delivery device generally provides a predetermined target dose of the drug to the subject, such as a therapeutically effective daily dose delivered over the course of a day; that is, the rate of release of the drug from the device provides substantially steady-state delivery of therapeutic concentrations of the drug to the subject.
[0996] Typically, for osmotic delivery devices, the volume of the beneficial agent chamber containing the beneficial agent formulation is between about 100 μl and about 1000 μl, more preferably between about 120 μl and about 500 μl, and even more preferably between about 150 μl and about 200 μl.
[0997] Typically, for example, an osmotic delivery device is implanted subdermally or subcutaneously in a subject to provide subcutaneous drug delivery. The device can be implanted subdermally or subcutaneously in either or both arms (e.g., on the inside, outside, or back of the upper arm) or in the abdomen. A preferred location in the abdominal region is under the abdominal skin in an area extending below the ribs and above the waistline. In order to provide multiple locations for implanting one or more osmotic delivery devices in the abdomen, the abdominal wall can be divided into the following four quadrants: a right upper quadrant extending at least 2-3 cm below the ribs on the right side, e.g., at least about 5-8 cm below the ribs on the right side and at least 2-3 cm to the right of the midline, e.g., at least about 5-8 cm to the right of the midline; a right lower quadrant extending at least 2-3 cm above the waistline, e.g., at least about 5-8 cm above the waistline and at least 2-3 cm to the right of the midline, e.g., at least about 5-8 cm to the right of the midline; a left upper quadrant extending at least 2-3 cm below the ribs on the left side, e.g., at least about 5-8 cm below the ribs on the left side and at least 2-3 cm to the left of the midline, e.g., at least about 5-8 cm to the left of the midline; and a left lower quadrant extending at least 2-3 cm above the waistline, e.g., at least about 5-8 cm above the waistline and at least 2-3 cm to the left of the midline, e.g., at least about 5-8 cm to the left of the midline. This provides multiple available locations for implantation of one or more devices on one or more occasions. Implantation and removal of osmotic delivery devices are generally performed by a medical professional using local anesthesia (eg, lidocaine).
[0998] Termination of treatment by removing the osmotic delivery device from the subject is straightforward and offers the important advantage of immediately ceasing delivery of the drug to the subject.
[0999] Preferably, the osmotic delivery device has a fail-safe mechanism to prevent the unintentional excessive or high-dose delivery of medicine in the theoretical situation of blocking or obstructing the outlet (diffusion regulator) of the pharmaceutical preparation. In order to prevent the unintentional excessive or high-dose delivery of medicine, the osmotic delivery device is designed and constructed so that the pressure required for partly or completely removes or discharges the diffusion regulator from the reservoir exceeds the pressure required for partly or completely removes or discharges the semipermeable membrane, to the necessary degree of reservoir decompression. In this case, pressure will be built in the device until it will outwardly push the semipermeable membrane at the other end, thus releasing osmotic pressure. The osmotic delivery device will become static subsequently and no longer deliver pharmaceutical preparation, and its condition is that piston and reservoir are sealing relationship.
[1000] Suspension formulations can also be used in infusion pumps, e.g. (DURECT Corporation, Cupertino, Calif.) osmotic pumps, which are small infusion pumps used for continuous drug delivery in laboratory animals such as mice and rats.
[1001] Example
[1002] The following examples are set forth so as to provide one of ordinary skill in the art with a complete disclosure and description of how to practice the invention and are not intended to limit the scope of what the inventors regard as their invention. Efforts have been made to ensure accuracy with respect to the numbers used (e.g., amounts, temperatures, and percentage changes), but some experimental errors and deviations should be considered. Unless otherwise indicated, temperatures are in degrees Celsius and pressures are at or near atmospheric.
[1003] Example 1: Generation of Amylin Analog Peptides
[1004] Amylin analog polypeptides of the present invention as provided in Table 3 were synthesized in N,N-dimethylformamide (DMF) using a solid-phase method using the Fmoc strategy with N-[(dimethylamino)-1H-1,2,3-triazolo-[4,5-b]pyridin-1-ylmethylene]-N-methylmethanium hexafluorophosphate N-oxide (HATU) or 2-(6-chloro-1-H-benzotriazol-1-yl)-1,1,3,3-tetramethylammonium hexafluorophosphate (HCTU) activation (5-fold molar excess of amino acid) on a Prelude peptide synthesizer (Protein Technologies Inc., Tucson, AZ). 20% piperidine / DMF solution was used for Fmoc deprotection. The resin used was Rink Amide MBHA LL (Novabiochem) with a loading of (0.30-0.40) mmol / g on a (20-400) μmol scale.
[1005] The peptide was deprotected and cleaved from the solid support by treating the resin with (92.5% TFA, 2.5% phenol, 2.5% water, and 2.5% triisopropylsilane) for 2-3 hours. Cold diethyl ether was used to precipitate the cleavage peptide. The diethyl ether was decanted, and the solid was wet-ground with cold diethyl ether again and pelletized by centrifugation. The crude solid was then dissolved in a 1:1 solution of ACN / water and 0.01% TFA. Disulfide bridge formation was obtained by adding a solution of iodine / acetic acid (35 mg / ml) to the crude product until the solution color uniformly became amber. The reaction solution was stirred until the reaction was complete as indicated by LC / MS analysis. A 2% solution of ascorbic acid in H2O was added until the solution became clear. The final crude product solution was lyophilized in preparation for final purification.
[1006] The lyophilized solid was redissolved in a 1:1 solution of acetonitrile / water and 0.1% TFA (10-15 mL) and analyzed by reverse phase HPLC on a Waters XBridge TM BEH 130, CIS, 10pm, Purification was performed on a 30 x 250 mm ID column using a 30 gradient ranging from 5-75% acetonitrile / water with 0.1% TFA over 30-45 minutes at a flow rate of 30 mL / min, λ-215 nm.
[1007] Example 2: Purification and characterization of amylin analog polypeptides, i.e., linear polypeptides without any lipophilic substituents and optional spacers
[1008] The purified product was lyophilized and analyzed by ESI-LC / MS and analytical HPLC and proved to be pure (>98%).The mass results were all consistent with the calculated values.
[1009] Characterization of the peptide analogs was performed via C18 HPLC and LC / MS analysis (Acquity SQD Waters Corp, Milford, MA) and UV detection provided by dual absorbance signals at 215 nm and 280 nm using one of Method A, Method B, Method C, or Method D.
[1010] Method A, LC / MS conditions: using Phenomenex UPLC Aeris TM Peptide XB C18 35 column, 1.7 μm, 2.1×100 mm or ACQUiTY BEH300 or BEH130 CT8 column, 1.77 μm, 2.1×100 mm, using 5-65% acetonitrile / water with 0.05% TFA over 30 minutes at a flow rate of 0.5 mL / min, λ-215 nm, 280 nm.
[1011] Method B, C18 HPLC conditions: UPLC analysis was performed on an Acquity BEH130, C18 column, 1.7 μm, 100×2.10 mm, at 25° C., 5-65% acetonitrile / water containing 0.05% TFA over 30 minutes, at a flow rate of 0.5 mL / min, at 1215 nm, 1280 nm.
[1012] Method C, UPLC conditions: UPLC analysis was performed on an Acquity BEH130, C18 column, 1.7 μm, 100×2.10 mm, at 25° C., 5-65% acetonitrile / water containing 0.05% TFA over 20 minutes, at a flow rate of 0.5 mL / min, at 1215 nm and 1280 nm.
[1013] Method D, UPLC conditions: UPLC analysis was performed on an Acquity BEH130, C18 column, 1.7 μm, 100×2.10 mm, at 25° C. using 5-65% acetonitrile / water containing 0.05% TFA over 10 minutes at a flow rate of 0.5 mL / min at 1215 nm and 1280 nm. 5.0 μL of sample was injected using the PLNO (partial loop with needle overfilled) injection mode.
[1014] Table 3 provides exemplary amylin analog polypeptides of the invention.
[1015] Polypeptide analogs without lipophilic substituents and optional spacers are sometimes referred to herein as "linear polypeptides." Polypeptide analogs with at least one covalently bound lipophilic substituent and optional spacer are sometimes referred to herein as "conjugated polypeptides."
[1016] Example 3: Synthesis of amylin analog polypeptide intermediates
[1017] Synthesis of polypeptides with modifications at positions such as D-Lys16 or L-Lys16 (Compounds B2, A129, B4, and B8)
[1018] After the synthesis of the linear peptide described in Example 1 was completed, the resin was washed with dichloromethane (DCM) and dried under vacuum for 30 minutes. For analogs containing an allyloxycarbonyl protecting group, its removal was facilitated by Pd(PPh3)3 in a solution of (chloroform / acetic acid / n-methylmorpholine, 37:2:1). The deprotected resin was washed with 2% sodium diethyldisulfide dicarbamate trihydrate / DMF (6 x 30 seconds), 2% DIEA / DMF (6 x 30 seconds), and finally DMF (6 x 30 seconds). Extension of the spacer region was performed in a stepwise manner with manual addition of each building block under pre-activated conditions. To 1 ml of a 200 mmol solution of Fmoc-γGlu-(OH)-OtBu in DMF was added 0.5 ml of DIEA (800 mmol), followed by 0.5 ml of HCTU (400 mmol), and the resulting reaction solution was stirred for 5 minutes, where it was added to the deprotected residue on the linear sequence. Under nitrogen, stirred reaction mixture 30 minutes. Discharge resin and wash with DMF (6 × 30 seconds). Use 20% piperidines / DMF to promote the subsequent removal of Fmoc protecting group, then carry out final washing with DMF (6 × 30 seconds). Carry out final deprotection and the cracking of peptide from solid support by treating resin 2-3 hour with (95% TFA, 2% water, 2% thioanisole and 1% triisopropylsilane). Along with using the method described above to be incorporated to each structural unit, separate and characterize each intermediate via HPLC / MS.
[1019] For example, synthesis of polypeptides with modifications at the N-terminus (A130, B22, and B23)
[1020] The synthesis of the linear sequence was carried out as described in Example 1. The addition of the albumin binding moiety was promoted by removing the N-terminal Fmoc protecting group via a 20% solution of piperidine / DMF. The resin was washed with DMF and the incorporation of the side chain building block was carried out in a stepwise manner under pre-activation conditions. 0.5 ml of DIEA (800 mmol) was added to a 200 mmol solution of 1 ml of Fmoc-γGlu-(OH)-OtBu in DMF, followed by 0.5 ml of HCTU (400 mmol). The resulting reaction solution was stirred for 5 minutes, wherein it was added to the deprotected linear sequence. The reaction mixture was stirred under nitrogen for 30 minutes. The resin was discharged and washed with DMF (6 × 30 seconds). The final deprotection and cleavage of the peptide from the solid support were carried out by treating the resin with (95% TFA, 2% water, 2% thioanisole and 1% triisopropylsilane) for 2-3 hours. Each intermediate was separated and characterized via HPLC / MS. The chemical data of both the internally modified polypeptide and the N-terminally modified polypeptide intermediate are recorded in Table 5 below.

[1022]
[1023] Example 4: Covalent attachment of a lipophilic substituent and an optional spacer to an amylin analog polypeptide, ie, conversion of a linear polypeptide into a conjugated polypeptide
[1024] The synthesis of amylin analog polypeptides conjugated to one or more albumin binding lipophilic substituents and an optional spacer was performed with modifications to the synthetic method described in Example 1 .
[1025] After the synthesis of the linear polypeptide as described in Example 1 is completed, the resin is washed with dichloromethane (DCM) and dried under vacuum for 30 minutes. For analogs containing allyloxycarbonyl protecting groups, their removal is achieved via a solution of Pd(PPh3)3 in (chloroform / acetic acid / n-methyl-morpholine, 37:2:1). For analogs containing BOC-Lys(Fmoc)-OH, the Fmoc protecting group is removed using 20% piperidine / DMF. The resulting deprotected resin is washed with DMF (6×30 seconds). Next, the extension of the spacer region is performed by manually adding each structural unit under pre-activation conditions in a stepwise manner. The addition of lipophilic substituents (also referred to as "acyl chains") is performed under normal SPPS conditions without a pre-activation step. The final deprotection and cleavage of the peptide from the solid support are performed by treating the resin with (95% TFA, 2% water, 2% thioanisole and 1% triisopropylsilane) for 2-3 hours. The cleavage peptide is precipitated using cold diethyl ether. The diethyl ether was decanted and the solid was triturated again with cold diethyl ether and pelletized by centrifugation.
[1026] The crude product was then dissolved in a solution of ACN / H2O, 0.1% TFA. A solution of iodine / acetic acid (35 mg / mL) was added to each crude peptide product solution until the solution color uniformly changed to amber. The reaction solution was stirred until LC / MS analysis indicated the desired disulfide bridges had formed. A 2% solution of ascorbic acid in H2O was added to the reaction solution until the solution became clear. The solution was frozen and lyophilized. Purification was achieved by the method described in Example 1.
[1027] An exemplary synthesis of conjugated peptides is described. Synthesis of A109: The synthesis of the linear sequence was performed as described in Example 1. The addition of the albumin binding moiety was facilitated by removing the N-terminal Fmoc protecting group via a 20% solution of piperidine / DMF. The resin was then washed with DMF and the incorporation of the side chain building blocks was performed in a stepwise manner under pre-activated conditions. To a 200mmol solution of 1ml Fmoc-γGlu-(OH)-OtBu in DMF was added 0.5ml DIEA (800mmol) followed by 0.5ml HCTU (400mmol). The resulting reaction solution was stirred for 5 minutes, whereupon it was added to the deprotected linear sequence. The reaction mixture was stirred under nitrogen for 30 minutes. Next, the resin was drained and washed with DMF (6×30 seconds). The Fmoc protecting group of γGlu was removed by 20% piperidine / DMF. This was followed by coupling with octadecanedioic acid (C18) (200 mmol) in DMF using HATU (400 mmol) and DIEA (800 mmol) under normal solid phase conditions.
[1028] Cleavage was achieved using a solution of 95% TFA / 2% water / 2% thioanisole / 1% TIPS. The crude product was then dissolved in a solution of ACN / H2O, 0.1% TFA. A solution of iodine / acetic acid (35 mg / mL) was added to the crude peptide product until the solution color became uniformly amber. The reaction solution was stirred until LC / MS analysis indicated that the desired disulfide bridges had formed. A 2% solution of ascorbic acid in H2O was added to the reaction solution until the solution became clear.
[1029] The crude product was lyophilized to give an off-white solid, which was purified via the method described in Example 2.
[1030] Example 5: Stability of Amylin Analog Polypeptides
[1031] Several amylin analog polypeptides described herein were tested for stability as trifluoroacetate salts in DMSO (i.e., an organosulfur solvent) or in 1 mg / ml aqueous solution (i.e., in deionized water). These analog polypeptides were incubated at 37° C., and samples were withdrawn at various time intervals and analyzed by LC / MS and HPLC to determine the purity and quality of the parent peptide and the extent of any degradation products. The purity results of these analyses are shown in Tables 6A and 6B and are considered indicative of stability.

[1041] Example 7: Functional Assays: Human Calcitonin Receptor and Amylin 3 Receptor
[1042] Activation of the human calcitonin receptor (hCTR) or the human amylin 3 receptor (hAMY3R) results in an increase in cellular cyclic adenosine monophosphate (cAMP). Accumulated cAMP can be measured in vitro using common detection methods in the presence of the nonspecific cAMP / cGMP phosphodiesterase inhibitor 3-isobutyl-1-methylxanthine (IBMX). Therefore, it is possible to estimate the in vitro potency (pEC50) of peptides for activating each of these receptors using fitted dose-response curves of cAMP accumulation.
[1043] Cells, culture, and cAMP assays
[1044] HEK293-CNG cells stably expressing human calcitonin receptor (hCTR) or co-expressed human calcitonin receptor and human receptor activity modifying protein 3 (hAMY3R) (Codex Biosolutions #CB-80200-258 and #CB-80-200-271, respectively) were grown in 90% DMEM, 10% FBS, 250 μg / ml G418, and 1 μg / ml puromycin (hCTR cells) or 90% DMEM, 10% FBS, 250 μg / ml G418, 1 μg / ml puromycin, 150 μg / ml hygromycin B (hAMY3R cells). Cells were maintained in growth medium for no more than 10 passages before testing.
[1045] On the day of the assay, cells expressing hCTR or hAMY3R were counted and plated at 500 cells per well in white 384-well OptiPlates (PerkinElmer #6007299) in 5 mcL of stimulation buffer consisting of 1X HBSS, 5 mM HEPES, 0.5 mM IBMX, and 0.1% bovine serum albumin (BSA) or 1X HBSS, 5 mM HEPES, 0.5 mM IBMX, and 0.1% casein with 0%, 0.1%, or 4% human serum albumin (HSA).
[1046] Peptides were serially diluted in the same buffer as above for each given assay condition. Two assay control solutions consisting of 50 mcM forskolin (cAMP system maximum) or assay buffer alone (cAMP system minimum) were also prepared in the appropriate stimulation buffer. Five microliters of each peptide concentration or assay control were added to triplicate wells and incubated at room temperature for thirty minutes. During this incubation step, 4× europium-labeled cAMP tracer solution and 4× tau were prepared according to the manufacturer's protocol (PerkinElmer LANCE Ultra cAMP kit). - Anti-cAMP solution (made with Ulight TMThe plate was incubated in an Envision fluorescent plate reader (PerkinElmer) for 60 minutes.
[1047] Data Analysis
[1048] Test values were first normalized to the mean and system minimum cAMP system values induced by forskolin using the following formula in Excel: (test value - mean system minimum) / (mean system maximum - mean system minimum) × 100. Normalized test values represent the baseline-corrected percentage of the maximum system cAMP response induced by forskolin. Normalized data were analyzed from triplicate assays and used to estimate the EC50 for each peptide at each receptor. Data were fit using a 4-parameter logistic curve model in GraphPad Prism software (v7.04): Y = bottom + (top - bottom) / (1 + 10^((LogEC50 - X))). Hill slope was constrained to 1.0. EC50 values were converted to pEC50 values using the following formula: pEC50 = -Log(EC50).
[1049] Data Description
[1050] For a given receptor, in vitro potency estimates in the absence of HSA (pEC50) were comparable across all peptides because they reflected albumin-independent binding (free peptide) values (0% HSA, Table 8). However, in the presence of albumin (BSA or HSA), potency measurements across the acylated peptides were not readily comparable (Table 8). This is due to the variability in albumin-acyl peptide binding efficiency, which generally depends on the amino acid sequence, acyl binding motif, attachment site, and linker length engineered into each peptide. However, for a given conjugated polypeptide, decreased potency (decreased pEC50 values) in the presence of HSA relative to the absence of HSA qualitatively indicates an albumin-peptide interaction (Table 8, Table 8). Figure 2A and Figure 2B In contrast, linear peptides (pramlintide, human calcitonin) were not affected by the presence of HSA (Table 8, Figure 2C and Figure 2D ), reflecting its poor albumin binding efficiency.

[1066] Example 12: Method for preparing plasma samples for pharmacokinetic studies
[1067] Protein precipitation
[1068] A 60 μL aliquot of each plasma sample was placed in a 96-well plate. 6 μL of 0.5% Tween-20 was added to each well. The plate was then vortexed at 1200 rpm for 10 minutes, after which 180 μL of 0.1% TFA / 2:1 ethanol:acetonitrile containing the appropriate internal standard was added to each well. The plate was vortexed at 1300 rpm for 5 minutes and then centrifuged at 2844 × g for 10 minutes. The supernatant (180 μL) was placed in a clean 96-well plate and evaporated at 45° C. under a stream of nitrogen. The residue was reconstituted in 80 μL of 20% acetonitrile (aqueous solution) containing 0.1% formic acid.
[1069] Solid Phase Extraction
[1070] A 60 mL aliquot of each plasma sample was diluted with 180 mL of 10 mM ammonium acetate (pH 6.8) containing the appropriate internal standard and loaded onto an Oasis WCX microElution plate (Waters Corporation, Milford, MA) that had been preconditioned with 200 mL of methanol and 200 mL of deionized water. The sample was washed sequentially with 200 mL of 5% ammonium hydroxide (aqueous) and 200 mL of 20% acetonitrile in water. The analyte was eluted with 200 mL of 5% formic acid / 75:25 acetonitrile:water. The eluent was dried under a stream of nitrogen. The residue was reconstituted in 80 μL of 20% acetonitrile (aqueous) containing 0.1% formic acid.

[1072] All calibration standards were prepared in control rat plasma containing K2EDTA and a protease inhibitor cocktail.
[1073] The HPLC-MS / MS was performed using a CTC HTS PAL autoinjector (Leap, Carrboro, NC), an Agilent Infinity 1290 system with a column oven (Palo Alto, CA), a Valco switching valve (Houston, TX), and an AB Sciex API 5600 TripleTOF TM Samples and standards were analyzed by TurboIonSpray™ UPLC-MS / MS using a system consisting of a 4000QTrap mass spectrometer (Framingham, MA) or a Sciex API 4000QTrap mass spectrometer (Framingham, MA). Samples were injected onto a 2.1×50 mm reverse-phase C18 analytical column, typically a Waters CORTECS UPLC C18+, 1.6 μm (Waters Corporation, Milford, MA) or similar column. Chromatographic separations were achieved using a gradient method using water (A) containing 0.1% formic acid and acetonitrile (B) containing 0.1% formic acid as the mobile phases. Initial conditions consisted of 90% A and 10% B. The organic component was increased to 95% B over a period of 3-4 minutes, depending on the peptide. A typical flow rate was 600 μL / min. The column temperature was kept constant at 40 or 50°C. Peptides were quantified by monitoring one or more product ions generated by multiple injections of the parent ion.
[1074] Example 14: In vivo efficacy of amylin analog polypeptides with food intake inhibition in rats
[1075] Acute food intake was continuously measured for a 72-hour period using the BioDAQ food monitoring system (Research Diets, New Brunswick, NJ) to determine the amount of food intake inhibition exhibited by these amylin analog polypeptides. Long Evans rats, approximately 8 weeks old, were obtained. Rats were individually housed and acclimated to a 45% high-fat diet for at least 2 weeks prior to dosing. After a 1-week acclimation period, all rats were individually housed in BioDAQ cages (Research Diets, New Brunswick, NJ) and maintained at a constant temperature (approximately 22° C.) and 30-70% relative humidity with a 12-hour light / dark cycle (lights on from 7:00 AM to 7:00 PM). Rats had ad libitum access to water and pelleted chow (Research Diets D12451i, 45 kcal% fat, Research Diets, New Brunswick, NJ). All procedures were performed in accordance with the USDA Animal Welfare Act and approved by the Mispro Institutional Animal Care and Use Committee. Animals were randomly assigned to treatment groups based on body weight (n=8 rats / group). Animals were dosed (SC bolus injection) with a specified concentration of amylin analog polypeptide or vehicle control (saline) and administered between 6:00 and 6:30 before lights out, with the hopper gated while the animals were being dosed. The hopper gate was opened and continuous data collection began immediately after dosing was completed. Data were analyzed using BioDAQ Viewer software (version 2.3.07) and, if necessary, round filters were set to reduce data noise associated with non-feeding behavior. All data were expressed as % inhibition compared to vehicle control and summarized as mean values. The statistical significance of the data was analyzed using Microsoft Excel (Redmond, WA) by a 2-sample t-test. P values < 0.05 were considered to indicate significant differences between treatment groups. The results of % inhibition of acute food intake for amylin analog polypeptide compared to vehicle control are shown in Table 10.

[1080] Example 15: In vivo efficacy and body weight changes in LE DIO rats after 13 days
[1081] A chronic (13 day) in vivo dose-response efficacy study was conducted in a rodent model of obesity (Long Evans (LE) diet-induced obesity (DIO) rats) to investigate the efficacy and durability of amylin analog peptides on weight loss. Male LE DIO rats (Envigo Laboratories, Inc., Indianapolis, IN) were used and were fed a high-fat diet (Teklad TD 95217, 40% kcal fat, Harlan Laboratories, Madison, WI) starting at weaning. Rats were 15-17 weeks of age at the start of the study. One rat was housed per cage and given ad libitum access to a high-fat diet (Harlan TD.95217, 4.3 kcal / g) and water, maintained on a 12 hour light / dark cycle from 5:00 AM to 5:00 PM at 21° C. and 50% relative humidity, and acclimated for at least 10 days prior to surgery. All procedures were performed in accordance with the USDA Animal Welfare Act and approved by the Mispro Institutional Animal Care and Use Committee. Body weight measurements were taken twice a week starting three days before surgery. Baseline fat mass and fat-free mass measurements were taken three days before starting peptide infusion using a QMR instrument (Echo Medical Systems, Houston, TX). Rats were randomly assigned to treatment groups (n=4-6 rats / group) based on their body fat mass percentage and / or body weight. Alzet mini-osmotic pumps (2 weeks; Model 2002, Durect Corporation, Cupertino, CA) were filled with vehicle or peptide under sterile conditions the day before surgery. On the day of surgery, rats were anesthetized under isoflurane and the dorsal skin surface was shaved and cleaned. Rats were injected SC with Flunexin (2.5 mg / kg). A 1-2 cm surgical incision was made between the shoulder blades. Blunt dissection was used to create a 2-3 cm subcutaneous tunnel into which a sterile, filled, mini-osmotic pump was introduced. The skin opening was closed with skin staples. Depending on its treatment group, one or two osmotic pumps containing vehicle or peptide were implanted in each rat. Data were analyzed using one-way ANOVA comparing each group to the appropriate control group in Excel and / or Prism (GraphPad Software, Inc., La Jolla, CA). P values < 0.05 were considered to indicate significant differences between treatment groups. The mean weight loss (%) compared to baseline and vehicle control (ΔΔ) from the 13-day study is shown in Table 9.
[1082] Example 16: Weight Loss Efficacy of Amylin Analog Peptides Combined with Exenatide in LE DIO Rats
[1083] A chronic study was conducted to determine the effects and persistence of continuous administration of an amylin analog polypeptide in combination with exenatide (a GLP-1 receptor agonist) on body weight after 27 days of treatment in LE DIO rats. 18-week-old male LE DIO rats (14 weeks on a high-fat diet) were subcutaneously (SC) implanted with two Alzet osmotic mini-pumps containing the indicated doses of an amylin analog polypeptide and / or exenatide (10 mcg / kg / d = ED50 for weight loss) or vehicle (20% DMSO in water) (n = 8 animals / treatment group). PK support for every-other-day dosing (eod) of an amylin analog polypeptide was given by SC injection every other day rather than mini-pump administration. All other procedures were the same as described for the previous example. The mean weight loss (%) results from the chronic combination study of exenatide compared to baseline and vehicle control (ΔΔ) are shown in Table 11.
[1084] Example 17: Antidiabetic Efficacy of Amylin Analog Peptides Combined with Exenatide in ZDF Rats
[1085] A chronic study was conducted to determine the antidiabetic effect of a combination of amylin analog peptide and exenatide on HbA1c (a primary antidiabetic parameter) after 27 days of treatment in Zucker diabetic fatty (ZDF) rats. Six-week-old male ZDF rats were obtained (Charles River, Raleigh, NC) and used for the study at 8 weeks of age. Upon receipt, rats were housed one animal per cage with free access to Purina 5008 chow (Lab Diet, St. Louis, MO) and water, maintained on a 12-hour light / dark cycle from 5:00 AM to 5:00 PM at 21° C. and 50% relative humidity, and acclimated for 9 days prior to the start of the study. Blood samples were obtained as prebleeds (day -3) via the tail vein to measure glucose levels and HbA1c. ZDF rats were randomly assigned to treatment groups (n=10 / group) with similar mean HbA1c and glucose. They were implanted subcutaneously (SC) with Alzet osmotic mini-pumps (2 pumps / animal) containing the indicated doses of amylin analog polypeptide and / or exenatide (10 mcg / kg / day) or vehicle (20% DMSO in water) (n=10 animals / treatment group). PK support was given by SC injection every other day rather than mini-pump administration of the amylin analog polypeptide administered every other day (eod). All other procedures were the same as described for the previous example. Blood samples were obtained again on days 14 and 27 (end of study) to measure glucose levels and HbA1c. A final whole blood sample (day 27) was collected by cardiac puncture under isoflurane anesthesia. HbA1c analysis was performed using a Carolina Chemistries CLC720i clinical chemistry analyzer (Mindray Inc., Mahwah, NY) using the protocol and method parameters described by the manufacturer. HbA1c results expressed as mean % change from baseline and vehicle control (ΔΔ) from the exenatide chronic combination study are shown in Table 11.
