Description

PROTEASE STABILIZED, ACYLATED INSULIN ANALOGUES
FIELD OF THIS INVENTION
The present invention relates to novel acylated insulin analogues exhibiting resistance towards prote- ases, a method for the preparation of such insulin analogues, insulin preparations containing the insulin analogues of the invention and a method of treating diabetes melhtus using these insulin analogues
BACKGROUND OF THIS INVENTION Diabetes melhtus is a metabolic disorder in which the ability to utilize glucose is partly or completely lost About 5% of all people suffer from diabetes and the disorder approaches epidemic proportions Since the introduction of insulin in the 1920 s, continuous efforts have been made to improve the treatment of diabetes mellitus Since people suffering from diabetes are subject to chronic treatment over several decades, there is a major need for safe, convenient and life quality improving insulin for- mulations
The oral route is by far the most widely used route for drug administration and is in general very well accepted by patients, especially for chronic therapies Administration of therapeutic peptides or proteins is however often limited to parenteral routes rather than the preferred oral administration due to several barriers such as enzymatic degradation in the gastrointestinal (Gl) tract and intestinal mucosa, drug efflux pumps, insufficient and variable absorption from the intestinal mucosa, as well as first pass metabolism in the liver
Normally, insulin formulations are administered by subcutaneous injection However, administration by other routes, e g , orally or pulmonary, would be advantageous due to patient compliance, safety and convenience Some of the commercial available insulin formulations are characterized by a fast onset of action and other formulations have a relatively slow onset but show a more or less prolonged action It is vary important for diabetic patients that there is, on the market, a big variety of insulins with different durations of actions (profiles of actions) Briefly, insulins can be classified as being short-, intermediate- or long-acting
WO 2008/034881 relates to certain insulin analogues wherein at least two hydrophobic amino acids have been substituted with hydrophilic amino acids which insulin analogues are not acylated
EP 2008/060733 and EP 2008/060733 relate to certain acylated insulin analogues wherein the insulin analogue comprises an elongation with an amino acid or a peptide residue connected C ter- mianly to the A21 amino acid
EP 2008/060734 relates to certain acylated insulins wherein an acyl moiety is attached to the parent insulin and wherein said acyl moiety comprises repeating units of alkylene glycol containing amino acids ASPECTS OF THIS INVENTION

SUMMARY OF THE INVENTION
It has been discovered that insulins that are stabilised towards proteolytic degradation (by specific mutations) and acylated at the B29-lysine are efficacious and protracted and possess high potential as protracted insulins that can be administered pulmonary or orally. The acylation confers binding to serum albumin, and, consequently, protraction. In addition, the acylated insulins of the invention display substantial reduction of insulin receptor affinity, compared to similar acylated insulins that are not stabilised towards proteolytic degradation This reduction in insulin receptor affinity of albumin-bound insulins of the invention contributes to the protraction of the acylated insulin in circulation, since insulin is internalised and degraded upon receptor activation. Hence, clearance of the insulins of the invention is reduced. The reduction of insulin receptor affinity does probably not cause a loss of potency, e.g., as measured in the hyperinsulinaemic euglycaemic clamp as described herein The combination of high albumin binding affinity and low insulin receptor affinity is, thus, beneficial for obtaining long duration of action of the insulins (basal insulins). Furthermore, after oral administration, these acylated insulins have a higher degree of bioavailability than similar known acylated insulins, that are not stabilised towards proteolytic degradation. Hence, these acylated insulin analogues are valuable for oral admini- stration. Similarly, after pulmonary administration, these acylated protease stabilised insulins displays higher apparent potency and/or bioavailability than similar known acylated insulins, that are not stabilised towards proteolytic degradation. Furthermore, these acylated protease stabilised insulins displays protracted time-action profiles when administered pulmonary to mammals. Hence, these acylated insulin analogues are valuable for pulmonary administration. The above-mentioned insulins that are stabilised towards proteolytic degradation are herein designated protease stabilised insulins.
The protease stabilised insulin molecule has a limited number of the naturally occurring amino acid residues substituted with other amino acid residues relative to human insulin as explained in the detailed part of the specification.

Other embodiments of protease stabilised insulins are mentioned below A "protease" or a "protease enzyme" is a digestive enzyme which degrades proteins and peptides and which is found in various tissues of the human body such as e g the stomach (pepsin), the intestinal lumen (chymotrypsin, trypsin, elastase, carboxypeptidases, etc ) or mucosal surfaces of the Gl tract (aminopeptidases, carboxypeptidases, enteropeptidases, dipeptidyl peptidases, endopep- tidases, etc ), the liver (Insulin degrading enzyme, cathepsin D etc), and in other tissues

An alternative way of measuring proteolytical stability is to measure the relative stability towards a comparator, e g , human insulin The relative stability is defines as T1/2/T1/4(comparator), where TV. and T1/2(compatator) are the half-lives of the analogue and the comparator, respectively, in the degradation assay In the examples section, the relative stability of selected insulins of the invention towards an enzyme mixture extracted from duodemum from rats is given (relative to human insulin as well as relative to a protease-resistant insulin without acylation) Protease cleavage sites (herein also mentioned as protease sites) are to be understood as amino acid residues that are recognized by proteases and/or amino acid residues whose peptide bond is cleaved by proteases Protease cleavage sites may be determined by determining cleavage "hot- spots" by HPLC, MS or LC-MS analyses and/or by prediction based on enzyme specificity of the pro- tease enzyme for which the protease cleavage site is to be determined A skilled person in the art will know how to determine protease cleavage sites for example based on enzyme specificities as for example described in Handbook of Proteolytical Enzymes, 2nd ed , Barrett, A J , Rawlmgs, N D , Woes- ner, J F editors, Elsevier Academic Press 2004 For example chymotrypsin is predicted to cleave peptide bonds C-terminal to aromatic residues (Trp, Tyr, Phe or Leu), that are not followed by Pro Simi- larly, trypsin is predicted to cleave peptide bonds C-terminal to basic residues Lys or Arg that are not followed by Pro, elastase is predicted to cleave residues C-terminal to Ala, VaI, GIy or Ser and car- boxypeptidase A will remove any C-terminal amino acid, but not Arg, Lys or Pro Insulin-degrading enzyme (IDE) is predicted to cleave the following positions of human insulin B9-10, B10-11 , B13-14, B14-15, B24-25, B25-26, A13-14 and A14-15 The term substituting (an) amino acid "within or in close proximity" to a protease

In a preferred embodiment a protease stabilised insulin is acylated in the A1 position, at the alpha nitrogen position of A1, and the protease stabilized insulin is comprising the B29R mutation The protease stabilised insulins are produced by expressing a DNA sequence encoding the insulin in question in a suitable host cell by well known technique as disclosed in, e g , US patent No 6,500,645 The protease stabilised insulin is either expressed directly or as a precursor molecule which has an N-terminal extension on the B-chain This N-terminal extension may have the function of increasing the yield of the directly expressed product and may be of up to 15 amino acid residues long The N-terminal extension is to be cleaved of in vitro after isolation from the culture broth and will therefore have a cleavage site next to B1 N-terminal extensions of the type suitable in this invention are disclosed in U S Patent No 5,395,922, and European Patent No 765,395A
The polynucleotide sequence coding for the protease stabilised insulin may be prepared synthetically by established standard methods, e g , the phosphoamidite method described by Beaucage et al (1981) Tetrahedron Letters 22 1859-1869, or the method described by Matthes et al (1984) EMBO Journal 3 801-805 According to the phosphoamidite method, oligonucleotides are synthesized, e g , in an automatic DNA synthesizer, purified, duplexed and ligated to form the synthetic DNA construct A currently preferred way of preparing the DNA construct is by polymerase chain reaction (PCR) The polynucleotide sequences may also be of mixed genomic, cDNA, and synthetic origin For example, a genomic or cDNA sequence encoding a leader peptide may be joined to a genomic or cDNA sequence encoding the A and B chains, after which the DNA sequence may be modified at a site by inserting synthetic oligonucleotides encoding the desired amino acid sequence for homologous recombination in accordance with well-known procedures or preferably generating the desired sequence by PCR using suitable oligonucleotides
The recombinant method will typically make use of a vector which is capable of replicating in the selected microorganism or host cell and which carries a polynucleotide sequence encoding the protease stabilised insulin The recombinant vector may be an autonomously replicating vector, / e , a vector which exists as an extra-chromosomal entity, the replication of which is independent of chromosomal replication, e g , a plasmid, an extra-chromosomal element, a mini-chromosome, or an artificial chromosome The vector may contain any means for assuring self-replication Alternatively, the vector may be one which, when introduced into the host cell, is integrated into the genome and replicated together with the chromosome(s) into which it has been integrated Furthermore, a single vector or plasmid or two or more vectors or plasmids which together contain the total DNA to be introduced into the genome of the host cell, or a transposon may be used The vector may be linear or closed circular plasmids and will preferably contain an element(s) that permits stable integration of the vector into the host cell's genome or autonomous replication of the vector in the cell independent of the genome The recombinant expression vector is capable of replicating in yeast Examples of sequences which enable the vector to replicate in yeast are the yeast plasmid 2 μm replication genes REP 1-3 and origin of replication
The vector may contain one or more selectable markers which permit easy selection of transformed cells A selectable marker is a gene the product of which provides for biocide or viral resistance, resistance to heavy metals, prototrophy to auxotrophs, and the like Examples of bacterial se- lectable markers are the dal genes from Bacillus subtilis or Bacillus licheniformis or markers which confer antibiotic resistance such as ampicillin, kanamycin, chloramphenicol or tetracycline resistance Selectable markers for use in a filamentous fungal host cell include amdS (acetamidase), argB (ornithine carbamoyltransferase), pyrG (orotιdιne-5'-phosphate decarboxylase) and trpC (anthranilate synthase Suitable markers for yeast host cells are ADE2, HIS3, LEU2, LYS2, MET3, TRP1 , and URA3 A well suited selectable marker for yeast is the Schizosaccharomyces pompe TPI gene (Russell (1985) Gene 40 125-130)
In the vector, the polynucleotide sequence is operably connected to a suitable promoter sequence The promoter may be any nucleic acid sequence which shows transcriptional activity in the host cell of choice including mutant, truncated, and hybrid promoters, and may be obtained from genes encoding extra-cellular or intra-cellular polypeptides either homologous or heterologous to the host cell
Examples of suitable promoters for directing the transcription in a bacterial host cell, are the promoters obtained from the E coli lac operon, Streptomyces coelicolor agarase gene {dagA), Bacillus subtilis levansucrase gene (sacS) Bacillus licheniformis alpha-amylase gene (amyL), Bacillus stearothermophilus maltogenic amylase gene (amyM), Bacillus amyloliquefaciens alpha-amylase gene (amyQ), and Bacillus licheniformis penicillinase gene (penP) Examples of suitable promoters for directing the transcription in a filamentous fungal host cell are promoters obtained from the genes for Aspergillus oryzae TAKA amylase, Rhizomucor miehei aspartic proteinase, Aspergillus niger neutral alpha-amylase, and Aspergillus niger acid stable alpha-amylase In a yeast host, useful promoters are the Saccharomyces cerevisiae Ma1 , TPI, ADH or PGK promoters
The polynucleotide sequence encoding the protease stabilised insulin will also typically be op- erably connected to a suitable terminator In yeast a suitable terminator is the TPI terminator (Alber et al (1982) J MoI Appl Genet 1 419-434) The procedures used to hgate the polynucleotide sequence encoding the protease stabilised insulin, the promoter and the terminator, respectively, and to insert them into a suitable vector containing the information necessary for replication in the selected host, are well known to persons skilled in the art It will be understood that the vector may be constructed either by first preparing a DNA construct containing the entire DNA sequence encoding the insulins of this invention, and subsequently inserting this fragment into a suitable expression vector, or by sequentially inserting DNA fragments containing genetic information for the individual elements (such as the signal, pro-peptide, connecting peptide, A and B chains) followed by ligation
The vector comprising the polynucleotide sequence encoding the protease stabilised insulin is introduced into a host cell so that the vector is maintained as a chromosomal integrant or as a self- replicating extra-chromosomal vector The term "host cell" encompasses any progeny of a parent cell that is not identical to the parent cell due to mutations that occur during replication The host cell may be a unicellular microorganism, e g , a prokaryote, or a non-unicellular microorganism, e g , a eu- karyote Useful unicellular cells are bacterial cells such as gram positive bacteria including, but not limited to, a Bacillus cell, Streptomyces cell, or gram negative bacteria such as E coli and Pseudomo- nas εp Eukaryote cells may be mammalian, insect, plant, or fungal cells In one embodiment, the host cell is a yeast cell The yeast organism may be any suitable yeast organism which, on cultivation, produces large amounts of the single chain insulin of the invention Examples of suitable yeast organisms are strains selected from the yeast species Saccharomyces cerevisiae, Saccharomyces kluyveri, Schizosaccharomyces pombe, Sacchoromyces uvarum, Kluyveromyces lactis, Hansenula polymor- pha, Pichia pastons, Pichia methanolica, Pichia kluyveri, Yarrowia lipolytica, Candida sp , Candida utilis, Candida cacaoi, Geotnchum sp , and Geotrichum fermentans
The transformation of the yeast cells may for instance be effected by protoplast formation followed by transformation in a manner known per se The medium used to cultivate the cells may be any conventional medium suitable for growing yeast organisms The secreted insulin, a significant proportion of which will be present in the medium in correctly processed form, may be recovered from the medium by conventional procedures including separating the yeast cells from the medium by cen- tnfugation, filtration or catching the insulin precursor by an ion exchange matrix or by a reverse phase absorption matrix, precipitating the proteinaceous components of the supernatant or filtrate by means of a salt, e g , ammonium sulphate, followed by purification by a variety of chromatographic procedures, e g , ion exchange chromatography, affinity chromatography, or the like

In one aspect, the neutral cyclic amino acid residue designated AA1 is an amino acid containing a saturated 6-membered carbocyclic ring, optionally containing a nitrogen hetero atom, and preferably the ring is a cyclohexane ring or a piperidine ring Preferably, the molecular weight of this neutral cyclic amino acid is in the range from about 100 to about 200 Da
The acidic amino acid residue designated AA2 is an amino acid with a molecular weight of up to about 200 Da comprising two carboxylic acid groups and one primary or secondary ammo group Alterna- tively, acidic amino acid residue designated AA2 is an amino acid with a molecular weight of up to about 250 Da comprising one carboxylic acid group and one primary or secondary sulphonamide group
The neutral, alkyleneglycol-containing amino acid residue designated AA3 is an alkyleneglycol moiety, optionally an oligo- or polyalkyleneglycol moiety containing a carboxylic acid functionality at one end and a amino group functionality at the other end Herein, the term alkyleneglycol moiety covers mono-alkyleneglycol moieties as well as ohgo- alkyleneglycol moieties Mono- and oligoalkyleneglycols comprises mono- and oligoethyleneglycol based, mono- and oligopropyleneglycol based and mono- and oligobutyleneglycol based chains, i e , chains that are based on the repeating unit -CH2CH2O-, -CH2CH2CH2O- or -CH2CH2CH2CH2O- The alkyleneglycol moiety is monodisperse (with well defined length / molecular weight) Monoalkyleneglycol moieties comprise -OCH2CH2O-, -OCH2CH2CH2O- or -OCH2CH2CH2CH2O- containing different groups at each end As mentioned herein, the order by which AA1, AA2 and AA3 appears in the acyl moiety with the formula (I) (Acy-AA1n-AA2m-AA3p-) can be interchanged independently. Consequently, the formula Acy- AA1n-AA2m-AA3p- also covers moieties like, e.g., the formula Acy-AA2m-AA1n-AA3p-l the formula Acy- AA2-AA3n-AA2-, and the formula Acy-AA3p-AA2m-AA1n-, wherein Acy, AA1 , AA2, AA3, n, m and p are as defined herein.
As mentioned herein, the connections between the moieties Acy, AA1 , AA2 and/or AA3 are formally obtained by amide bond (peptide bond) formation (-CONH-) by removal of water from the parent compounds from which they formally are build. This means that in order to get the complete formula for the acyl moiety with the formula (I) (Acy-AA1n-AA2m-AA3p-, wherein Acy, AA1, AA2, AA3, n, m and p are as defined herein), one has, formally, to take the compounds given for the terms Acy, AA1 , AA2 and AA3 and remove a hydrogen and/or hydroxyl from them and, formally, to connect the building blocks so obtained at the free ends so obtained.

PHARMACEUTICAL COMPOSITIONS The acylated insulins of this invention may be administered subcutaneously, nasally, orally, or pulmonary
For subcutaneous administration, the acylated insulins of this invention are formulated analogously with the formulation of known insulins Furthermore, for subcutaneous administration, the acylated insulins of this invention are administered analogously with the administration of known insulins and, generally, the physicians are familiar with this procedure
Acylated insulins of this invention may be administered by inhalation in a dose effective to increase circulating insulin levels and/or to lower circulating glucose levels Such administration can be effective for treating disorders such as diabetes or hyperglycemia Achieving effective doses of insulin requires administration of an inhaled dose of more than about 0 5 μg/kg to about 50 μg/kg of acylated insulins of this invention A therapeutically effective amount can be determined by a knowledgeable practitioner, who will take into account factors including insulin level, blood glucose levels, the physical condition of the patient, the patient's pulmonary status or the like The acylated insulins of this invention may be delivered by inhalation to achieve slow absorption and/or reduced systemical clearance thereof Different inhalation devices typically provide similar pharmacokinetics when similar particle sizes and similar levels of lung deposition are compared
The acylated insulins of this invention may be delivered by any of a variety of inhalation devices known in the art for administration of a therapeutic agent by inhalation These devices include metered dose inhalers, nebulizers, dry powder generators, sprayers, and the like Preferably, the acylated insulins of this are delivered by a dry powder inhaler or a sprayer There are a several desirable features of an inhalation device for administering acylated insulins of this invention For example, delivery by the inhalation device is advantageously reliable, reproducible, and accurate The inhalation device should deliver small particles or aerosols, e g , less than about 10 μm, for example about 1-5 μm, for good respirability Some specific examples of commercially available inhalation devices suitable for the practice of this invention are Turbohaler™ (Astra), Rotahaler® (Glaxo), Diskus® (Glaxo), Spiros™ inhaler (Dura), devices marketed by Inhale Therapeutics, AERx™ (Aradigm), the Ultravent® nebulizer (Mallinckrodt), the Acorn II® nebulizer (Marquest Medical Products), the Ventolin® metered dose inhaler (Glaxo), the Spinhaler® powder inhaler (Fisons), or the like As those skilled in the art will recognize, the formulation of acylated insulins of this invention, the quantity of the formulation delivered and the duration of administration of a single dose depend on the type of inhalation device employed For some aerosol delivery systems, such as nebulizers, the frequency of administration and length of time for which the system is activated will depend mainly on the concentration of acylated insulins in the aerosol For example, shorter periods of administration can be used at higher concentrations of acylated insulins in the nebulizer solution Devices such as metered dose inhalers can produce higher aerosol concentrations and can be operated for shorter periods to deliver the desired amount of the acylated insulins Devices such as powder inhalers deliver active agent until a given charge of agent is expelled from the device In this type of inhaler, the amount of insulin acylated insulins of this invention in a given quantity of the powder determines the dose delivered in a single administration
The particle size of acylated insulins of this invention in the formulation delivered by the inhalation device is critical with respect to the ability of insulin to make it into the lungs, and preferably into the lower airways or alveoli Preferably the acylated insulins of this invention ion is formulated so that at least about 10% of the acylated insulins delivered is deposited in the lung, preferably about 10 to about 20%, or more It is known that the maximum efficiency of pulmonary deposition for mouth breathing humans is obtained with particle sizes of about 2 μm to about 3 μm When particle sizes are above about 5 μm, pulmonary deposition decreases substantially Particle sizes below about 1 μm cause pulmonary deposition to decrease, and it becomes difficult to deliver particles with sufficient mass to be therapeutically effective Thus, particles of the acylated insulins delivered by inhalation have a particle size preferably less than about 10 μm, more preferably in the range of about 1 μm to about 5 μm The formulation of the acylated insulins is selected to yield the desired particle size in the chosen inhalation device
Advantageously for administration as a dry powder an acylated insulin of this invention is pre- pared in a particulate form with a particle size of less than about 10 μm, preferably about 1 to about 5 μm The preferred particle size is effective for delivery to the alveoli of the patient's lung Preferably, the dry powder is largely composed of particles produced so that a majority of the particles have a size in the desired range Advantageously, at least about 50% of the dry powder is made of particles having a diameter less than about 10 μm Such formulations can be achieved by spray drying, milling, or critical point condensation of a solution containing the acylated insulin of this invention and other desired ingredients Other methods also suitable for generating particles useful in the current invention are known in the art
The particles are usually separated from a dry powder formulation in a container and then transported into the lung of a patient via a carrier air stream Typically, in current dry powder inhalers, the force for breaking up the solid is provided solely by the patient's inhalation In another type of inhaler, air flow generated by the patient's inhalation activates an impeller motor which deagglomerates the particles
Formulations of acylated insulins of this invention for administration from a dry powder inhaler typically include a finely divided dry powder containing the derivative, but the powder can also include a bulking agent, carrier, excipient, another additive, or the like Additives can be included in a dry powder formulation of acylated insulin, e g , to dilute the powder as required for delivery from the particular powder inhaler, to facilitate processing of the formulation, to provide advantageous powder properties to the formulation, to facilitate dispersion of the powder from the inhalation device, to stabilize the formulation (for example, antioxidants or buffers), to provide taste to the formulation, or the like Advan- tageously, the additive does not adversely affect the patient's airways The acylated insulin can be mixed with an additive at a molecular level or the solid formulation can include particles of the acylated insulin mixed with or coated on particles of the additive Typical additives include mono-, dι-, and polysaccharides, sugar alcohols and other polyols, such as, e g , lactose, glucose, raffmose, melezitose, lactitol, maltitol, trehalose, sucrose, manmtol, starch, or combinations thereof, surfactants, such as sorbitols, diphosphatidyl choline, or lecithin, or the like Typically an additive, such as a bulking agent, is present in an amount effective for a purpose described above, often at about 50% to about 90% by weight of the formulation Additional agents known in the art for formulation of a protein such as insulin analogue protein can also be included in the formulation
A spray including the acylated insulins of this invention can be produced by forcing a suspen- sion or solution of the acylated insulin through a nozzle under pressure The nozzle size and configuration, the applied pressure, and the liquid feed rate can be chosen to achieve the desired output and particle size An electrospray can be produced, e g , by an electric field in connection with a capillary or nozzle feed Advantageously, particles of insulin conjugate delivered by a sprayer have a particle size less than about 10 μm, preferably in the range of about 1 μm to about 5 μm Formulations of acylated insulins of this invention suitable for use with a sprayer will typically include the acylated insulins in an aqueous solution at a concentration of from about 1 mg to about 500 mg of the acylated insulin per ml of solution Depending on the acylated insulin chosen and other factors known to the medical advisor, the upper limit may be lower, e g , 450, 400, 350, 300, 250, 200, 150, 120, 100 or 50 mg of the acylated insulin per ml of solution The formulation can include agents such as an excipient, a buffer, an isotonicity agent, a preservative, a surfactant, and, preferably, zinc The formulation can also include an excipient or agent for stabilization of the acylated insulin, such as a buffer, a reducing agent, a bulk protein, or a carbohydrate Bulk proteins useful in formulating insulin conjugates include albumin, protamine, or the like Typical carbohydrates useful in formulating the acy- lated insulin include sucrose, mannitol, lactose, trehalose, glucose, or the like The acylated insulins formulation can also include a surfactant, which can reduce or prevent surface-induced aggregation of the insulin conjugate caused by atomization of the solution in forming an aerosol Various conventional surfactants can be employed, such as polyoxyethylene fatty acid esters and alcohols, and polyoxy- ethylene sorbitol fatty acid esters Amounts will generally range between about 0 001 and about 4% by weight of the formulation

A composition for nasal administration of an acylated insulins of this invention may, e g , be prepared as described in European Patent No 272,097 Oral preparations containing an acylated protease stabilised insulin of this inventions can be prepared in a manner known perse One way of making preparations containing an acylated protease stabilised insulin of this invention which can conveniently be administered orally is by using a procedure which is analagous to the process described in WO 2008/145728 Another way of preparing oral preparations containing an acylated protease stabilised insulin of this invention is to prepare a water-free liquid or semisolid pharmaceutical compositions comprising an acylated protease stabilised insulin of this invention (a), at least one polar organic solvent (b) for the acylated protease stabilised insulin, at least one lipophilic component (c), and optionally a surfactant (d) and/or at least one solid hydrophilic component (e) This could be in the form of an oily solu- tion Alternatively, the at least one solid hydrophilic component (d) is at least one solid hydrophilic polymer Alterantively, the pharmaceutical composition comprising at least one solid hydrophilic component is free of surfactant, wherein said surfactant has an HLB value which is at least 8, i e there is no surfactant, which has an HLB value which is at least 8, present in the composition
For example, a pharmaceutical composition contining an acylated protease stabilised insulin may be a water-free oily solution and/or a SEDDS or SMEDDS pharmaceutical composition
Alternatively said pharmaceutical composition is a self emulsifying drug delivery system (herein designated SEDDS)
It is believed that the high solubility of an acylated protease stabilised insulin in the polar organic solvent of the pharmaceutical composition resulting in the relatively low total amount of polar organic solvent needed in said pharmaceutical composition may improve compatibility of the pharmaceutical composition with capsule materials
The pharmaceutical composition may contain a carrier that comprises a lipophilic component, a surfactant and a polar organic solvent and optionally a solid hydrophilic component (e) If there is a solid hydrophilic component present, at least one of the components selected from the group con- sisting of a lipophilic component and a surfactant is liquid or semi-solid If there is a liquid hydrophilic component (e) present, both the lipophilic component and the surfactant may be solid For example, the surfactant is liquid or semisolid In one aspect, a solid hydrophilic component is present
As used herein, the term "carrier" refers to the pharmaceutically acceptable vehicle that transports the therapeutically active water-soluble polypeptide across the biological membrane or within a biological fluid The carrier comprises a lipophilic component and a polar organic solvent, and optionally a solid hydrophilic component and/or a surfactant The carrier is capable of spontaneously producing an emulsion or colloidal structures, when brought in contact dispersed, or diluted, with an aqueous medium, e g , water, fluids containing water, or in vivo media in mammals, such as the gastric juices of the gastrointestinal tract The colloidal structures can be solid or liquid particles including domains, droplets, micelles, mixed micelles, vesicles and nanoparticles
For example, when the pharmaceutical composition is brought into contact with an aqueous medium, an emulsion, such as a microemulsion, spontaneously forms In particular, an emulsion or microemulsion forms in the digestive tract of a mammal when the delivery system is orally ingested In addition to the aforementioned components, the spontaneously dispersible preconcentrate can also optionally contain other excipients, such as buffers, pH adjusters, stabilizers and other adjuvants recognized by one of ordinary skill in the art to be appropriate for such a pharmaceutical use
The term "water-free" as used herein refers to a composition to which no water is added during preparation of the pharmaceutical composition The acylated protease stabilised insulin and/or one or more of the excipients in the pharmaceutical composition may have small amounts of water bound to it before preparing a pharmaceutical composition Fore example, a water-free pharmaceutical composition comprises less than 10% w/w water, for example, less than 5% w/w water, for example, less than 4% w/w water, for example, less than 3% w/w water, for example, less than 2% w/w water, for example, less than 1% w/w water As used herein, the term "microemulsion preconcentrate" means a composition, which spontaneously forms a microemulsion, e g , an oιl-ιn-water microemulsion, in an aqueous medium, e g , in water or in the gastrointestinal fluids after oral application The composition self-emulsifies upon dilution in an aqueous medium for example in a dilution of 1 5, 1 10, 1 50, 1 100 or higher
Due to the high solubility of the acylated protease stabilised insulin, the total amount of polar organic solvent in the SEDDS can be kept low which on the one hand improves compatibility of the formulation with capsule materials and on the other hand gives more design space for the composition
The pharmaceutical composition comprises a lipophilic component, and an organic polar component The components of the drug delivery system can be present in any relative amounts For example, the drug delivery system can comprises up to 40% polar organic component by weight of the composition of the carrier, e g , less than 30%, 20%, 15% or 10% In another aspect, the drug delivery system comprises from 5% to 40% by weight polar organic solvent of the total composition of the carrier In yet a further aspect, the drug delivery system comprises from 10% to 30 % by weight polar organic solvent of the total composition of the carrier The pharmaceutical composition may be in the form of a non-powder composition, i e in a semi-solid or liquid form
As used herein, the term "liquid" means a component or composition that is in a liquid state at room temperature ("RT"), and having a melting point of, for example, below 20°C As used herein room temperature (RT) means approximately 20-25°C As used herein, the term "semi-solid" relates to a component or composition which is not liquid at room temperature, e g , having a melting point between room temperature and about 40°C A semisolid can have the qualities and/or attributes of both the solid and liquid states of matter As used- herein, the term "solidify" means to make solid or semi-solid
Examples of semi-solid or liquid compositions are pharmaceutical compositions in the form of, e g , oils, solutions, liquid or semisolid SMEDDS and liquid or semisolid SEDDS

Polar organic solvents may be selected from solvent wherein the acylated proteases stabilised insulin show better solubility in said polar organic solvents than in other solvents Hence, the acylated proteases stabilised insulin can be dissolved to a high degree in a water-free pharmaceutical acceptable polar organic solvent such as propylene glycol, glycerol and PEG200 For example, at least 20% (w/w) of the acylated proteases stabilised insulin dissolve in a water-free pharmaceutical acceptable polar organic solvent, i e when adding 20% w/w of the acylated proteases stabilised insulin to the polar organic solvent, a clear solution is obtained In another aspect at least 25%, 30%, 40% or 50% (w/w) of the acylated proteases stabilised insulin dissolve in a water- free pharmaceutical acceptable polar organic solvent
The polar organic solvent may thus refer to a hydrophilic, water miscible carbon-containing solvent that contains an O-H or N-H bond, or mixtures thereof The polarity is reflected in the dielectric constant or the dipole moment of a solvent The polarity of a solvent determines what type of com- pounds it is able to dissolve and with what other solvents or liquid compounds it is miscible Typically, polar solvents dissolve polar compounds best and non-polar solvents dissolve non-polar compounds best "like dissolves like" Strongly polar compounds like inorganic salts (e g sodium chloride) dissolve only in very polar solvents

When using the term "pH optimized" it is herein meant that the acylated protease stabilsed insulin has been dehydrated at a target pH which is at least 1 pH unit from the pi of the acylated protease stabilsed insulin in aqueous solution Thus, the target pH is more than 1 pH unit above the isoelectric point of the acylated protease stabilised insulin Alternatively, the target pH is more than 1 pH unit below the isoelectric point of the acylated protease stabilised insulin Hence, the target pH could be more than 1 5 pH units above or below the pi, for example, 2 0 pH units or more above or below the pi, for example, 2 5 pH units or more above or below the pi of the acylated protease stabil- sed insulin
The term "dehydrated" as used herein in connection with an acylated protease stabilsed insulin refers to a denvatized acylated protease stabilsed insulin which has been dried from an aqueous solution The term "target pH" as used herein refers to the aqueous pH which will establish when the dehydrated acylated protease stabilsed insulin is rehydrated in pure water to a concentration of ap- proximately 40 mg/ml or more The target pH will typically be identical to the pH of the aqueous solution of the acylated protease stabilsed insulin from which the acylated protease stabilsed insulin was recovered by drying However, the pH of the acylated protease stabilsed insulin solution will not be identical to the target pH, if the solution contains volatile acids or bases It has been found that the pH history of the acylated protease stabilsed insulin will be determinant for the amount of the acylated protease stabilsed insulin, which can be solubilized in the polar organic solvent
The term "the pi of the polypeptide" as used herein refers to the isoelectric point of a polypeptide
The term "isoelectric point" as used herein means the pH value where the overall net charge of a macromolecule such as a peptide is zero In peptides there may be several charged groups, and at the isoelectric point the sum of all these charges is zero At a pH above the isoelectric point the overall net charge of the peptide will be negative, whereas at pH values below the isoelectric point the overall net charge of the peptide will be positive
The pi of a protein can be determined experimentally by electrophoresis techniques such as electrofocusing A pH gradient is established in an anticonvective medium, such as a polyacrylamide gel
When a protein is introduced in to the system it will migrate under influence of an electric field applied across the gel Positive charged proteins will migrate to the cathode Eventually, the migrating protein reaches a point in the pH gradient where its net electrical charge is zero and is said to be focused This is the isoelectric pH (pi) of the protein The protein is then fixed on the gel and stained The pi of the protein can then be determined by comparison of the position of the protein on the gel relative to marker molecules with known pi values
The net charge of a protein at a given pH value can be estimated theoretically by a person skilled in the art by conventional methods In essence, the net charge of protein is the equivalent to the sum of the fractional charges of the charged amino acids in the protein aspartate (β-carboxyl group), glutamate (δ-carboxyl group), cysteine (thiol group), tyrosine (phenol group), histidine (imidazole side chains), lysine (ε-ammonium group) and arginine (guanidimum group) Additonally, one should also take into account charge of protein terminal groups (α-NH2 and α-COOH) The fractional charge of the ionisable groups can be calculated from the intrinsic pKa values The drying, i e , dehydration of the acylated protease stabilised insulin can be performed by any conventional drying method such, e g , by spray-, freeze-, vacuum-, open - and contact drying For example, the acylated protease stabilsed insulin solution is spray dried to obtain a water content below about 10%, for example, below about 8%, below about 6%, below about 5%, below about 4%, below about 3%, below about 2% or below about 1% calculated on/measured by loss on drying test (gravimetric) as stated in the experimental part
Fore example, the acylated protease stabilised insulin is spray dried or freeze-dned Compositions containing acylated protease stabilised insulins of this invention can be used in the treatment of states which are sensitive to insulin Thus, they can be used in the treatment of type 1 diabetes, type 2 diabetes and hyperglycaemia for example as sometimes seen in seriously injured persons and persons who have undergone major surgery The optimal dose level for any patient will depend on a variety of factors including the efficacy of the specific insulin derivative employed, the age, body weight, physical activity, and diet of the patient, on a possible combination with other drugs, and on the severity of the state to be treated It is recommended that the daily dosage of the acylated insulin of this invention be determined for each individual patient by those skilled in the art in a similar way as for known insulin compositions

General procedure for the solid phase synthesis of acylation reagents of the general formula (II):
(II) Acy-AA1n-AA2m-AA3p-Act,
wherein Acy, AA1 , AA2, AA3, n, m, and p are as defined above and Act is the leaving group of an active ester, such as Λ/-hydroxysuccιnιmιde (OSu), or 1-hydroxybenzotrιazole, and wherein carboxylic acids within the Acy and AA2 moieties of the acyl moiety are protected as fe/t-butyl esters
Compounds of the general formula (II) according to the invention can be synthesised on solid support using procedures well known to skilled persons in the art of solid phase peptide synthesis This procedure comprises attachment of a Fmoc protected amino acid to a polystyrene 2-chlorotπtylchlorιde resin The attachment can, e g , be accomplished using the free N-protected amino acid in the presence of a tertiary amine, like triethyl amine or Λ/,Λ/-dιιsopropylethylamιne (see references below) The C-terminal end (which is attached to the resin) of this amino acid is at the end of the synthetic sequence being coupled to the parent insulins of the invention After attachment of the Fmoc amino acid to the resin, the Fmoc group is deprotected using, e g , secondary amines, like piperidine or diethyl amine, followed by coupling of another (or the same) Fmoc protected amino acid and deprotection The synthetic sequence is terminated by coupling of mono-fert-butyl protected fatty (α, ω) diacids, like hexadecanedioic, heptadecanedioic, octadecanedioic or eicosanedioic acid mono-fert-butyl esters Cleavage of the compounds from the resin is accomplished using diluted acid like 0 5-5% TFA/DCM (trifluoroacetic acid in dichloromethane), acetic acid (e g , 10% in DCM, or HOAc/triflouroethanol/DCM 1 1 8), or hecafluoroisopropanol in DCM (See , e g , "Organic Synthesis on Solid Phase", F Z Dor- wald, Wiley-VCH, 2000 ISBN 3-527-29950-5, "Peptides Chemistry and Biology", N Sewald & H -D Jakubke, Wiley-VCH, 2002, ISBN 3-527-30405-3 or The Combinatorial Cheemistry Catalog" 1999, Novabiochem AG, and references cited therein) This ensures that fert-butyl esters present in the compounds as carboxylic acid protecting groups are not deprotected Finally, the C-terminal carboxy group (liberated from the resin) is activated, e g , as the /V-hydroxysuccinimide ester (OSu) and used either directly or after purification as coupling reagent in attachment to parent insulins of the invention This procedure is illustrated in example 9
Alternatively, the acylation reagents of the general formula (II) above can be prepared by solution phase synthesis as described below
Mono-fert-butyl protected fatty diacids, such as hexadecanedioic, heptadecanedioic, octadecanedioic or eicosanedioic acid mono-fert-butyl esters are activated, e g , as OSu-esters as described below or as any other activated ester known to those skilled in the art, such as HOBt- or HOAt-esters This active ester is coupled with one of the amino acids AA1 , mono-fert-butyl protected AA2, or AA3 in a suit- able solvent such as THF, DMF, NMP (or a solvent mixture) in the presence of a suitable base, such as DIPEA or triethylamine The intermediate is isolated, e g , by extractive procedures or by chromatographic procedures The resulting intermediate is again subjected to activation (as described above) and to coupling with one of the amino acids AA1 mono-fert-butyl protected AA2, or AA3 as described above This procedure is repeated until the desired protected intermediate Acy-AA1n-AA2m-AA3p-OH is obtained This is in turn activated to afford the acylation reagents of the general formula (II) Acy- AA1n-AA2m-AA3p-Act This procedure is illustrated in example 21
The acylation reagents prepared by any of the above methods can be (fert-butyl) de-protected after activation as OSu esters This can be done by TFA treatment of the OSu-activated fert-butyl protected acylation reagent After acylation of any protease stabilised insulin, the resulting unprotected acylated protease stabilised insulin of the invention is obtained This is illustrated eg in example 16 below
If the reagents prepared by any of the above methods are not (ferf-butyl) de-protected after activation as OSu esters, acylation of any protease stabilised insulin affords the corresponding fert-butyl pro- tected acylated protease stabilised insulin of the invention In order to obtain the unprotected acylated protease stabilised insulin of the invention, the protected insulin is to be de-protected This can be done by TFA treatment to afford the unprotected acylated protease stabilised insulin of the invention This is illustrated, e g , in examples 1 and 2 below
If acylation of a lysine residue (in the epsilon position) of an insulin is desired, acylation is performed at alkaline pH (eg at pH 10, 10 5, or 11 ) This is, e g , illustrated in examples 1 and 2 below
If acylation of the A-chain N-terminal position (A1) of an insulin is desired, acylation is performed at neutral pH (eg at pH 7, 7 5, 8, or 8 5) This is, e g , illustrated in examples 38, and 44 below

Example 178, Insulin receptor affinity of selected insulin derivatives of the invention
The affinity of the acylated insulin analogues of this invention for the human insulin receptor is deter- mined by a SPA assay (Scintillation Proximity Assay) microtiterplate antibody capture assay SPA- PVT antibody-binding beads, anti-mouse reagent (Amersham Biosciences, Cat No PRNQ0017) are mixed with 25 ml of binding buffer (100 mM HEPES pH 7 8 100 mM sodium chloride, 10 mM MgSO4, 0 025% Tween-20) Reagent mix for a single Packard Optiplate (Packard No 6005190) is composed of 2 4 μl of a 1 5000 diluted purified recombinant human insulin receptor (either with or without exon 11), an amount of a stock solution of A14Tyr[125l]-human insulin corresponding to 5000 cpm per 100 μl of reagent mix, 12 μl of a 1 1000 dilution of F12 antibody, 3 ml of SPA-beads and binding buffer to a total of 12 ml A total of 100 μl reagent mix is then added to each well in the Packard Optiplate and a dilution series of the insulin derivative is made in the Optiplate from appropriate samples The samples are then incubated for 16 hours while gently shaken The phases are the then separated by centπfu- gation for 1 mm and the plates counted in a Topcounter The binding data were fitted using the nonlinear regression algorithm in the GraphPad Prism 2 01 (GraphPad Software, San Diego CA) and affinities are expressed relative (in pertcentage (%)) to the affinity of human insulin
A related assay is also used wherein the binding buffer also contains 4 5%HSA in order to mimic physiological conditions

Example 179, Hydrophobics of the insulin derivatives of the invention
The hydrophobicity of an insulin derivative is found by reverse phase HPLC run under isocratic conditions The elution time of the insulin derivative is compared to that of human insulin (herein designated HI) or another derivative with a known hydrophibicity under the same conditions The hydrophobicity, k'rel, is calculated as k'relderiv - ((tdenv-to)/(trerto))*k'relref Using HI as reference k'relref = k'relHι = 1 The void time of the HPLC system, to, is determined by injecting 5 μl of 0 1 mM NaNO3 Runing conditions
Column Lichrosorb RP-C18, 5μm, 4 x 250 mm Buffer A 0 1 M natrium phosphate pH 7 3, 10 vol% CH3CN Buffer B 50 vol% CH3CN Injection volume 5 μl Run time max 60 minutes
After running an initial gradient, the isocratic level for running the derivative and reference (for example HI) is chosen, and the elution times of the derivative and reference under isocratic conditions are used in the above equation to calculate k'reldeπv

Protocol:
The test substance will be dosed pulmonary by the drop instillation method In brief, male Wistar rats (app 250 g) are anaesthesized in app 60 ml fentanyl/dehydrodenzperιdol/-dormιcum given as a 6 6 ml/kg sc primingdose and followed by 3 maintainance doses of 3 3 ml/kg sc with an interval of 30 mm Ten minutes after the induction of anaesthesia, basal samples are obtained from the tail vein (t = -20 mm) followed by a basal sample immediately prior to the dosing of test substance (t=0) At t=0, the test substance is dosed intra tracheally into one lung A special cannula with rounded ending is mounted on a syringe containing the 200 ul air and test substance (1 ml/kg) Via the orifice, the cannula is introduced into the trachea and is forwarded into one of the main bronchi - just passing the bifurcature During the insertion, the neck is palpated from the exterior to assure intratracheal positioning The content of the syringe is injected followed by 2 sec pause Thereafter, the cannula is slowly drawn back The rats are kept anaesthesized during the test (blood samples for up to 4 or 8 hrs) and are euthanized after the experiment Figs 8 and 9 show blood glucose lowering effects and plasma insulin concentrations, respectively, from intratracheal drop instillation of an insulin of the invention (example 9) compared with a similar, but non-protease resistant insulin of the prior art (example 183)
Example 181, Pulmonary delivery of insulin derivatives to mini-pigs
Protocol: The pigs were instrumented with central venous catheters for intravenous injections and blood sampling The pigs are fasted prior to the pulmonary experiment, i e the day before dosing, the leftovers from the afternoon feeding is removed approximately one hour after feeding and on the day of dosing, the pigs are not fed The patency of the catheters is checked prior to the experiment with saline added 10 IU/ml heparin
After pulmonary dosing, a glucose solution should be ready for i v injection to prevent hypoglycaemia, i e 4-5 syringes (20 ml) are filled with sterile 20 % glucose, ready for use Diagnosis of hypoglycemia is based on clinical symptoms and blood glucose measurements on a glucometer (Glucocard X-meter) Treatment consists of slow i v injection 50-100 ml 20% glucose (10-20 g glucose) The glucose is given in fractions over 5-10 minutes until effect
The pigs are fasted during the first part of the experiment (until 24 h), but with free access to water After the 16 h blood sample catheters are closed with 5000 IU/ml heparin, placed in the pockets and the pigs are released After the 24 h blood sample the pigs are fed with double ration of food and apples Pigs are not fasted from 24 h to 48 h
Compound and pulmonary dosing
Powder for pulmonary dosing The insulin powders are weighed into 8 separate powder chamber of the dry powder device (PennCentury™ Model DP-4, custom made porcine device) the day before the experiment All chambers are kept protected from light and humidity by keeping them on a desiccating material in a container with aluminumfoil around in a temperature and humidity controlled laboratory until dosing
Based on the most recent individual animal weight, the delivery device was preloaded with 25 nmol/kg as some powder retention was expected
Loading dose = (Weight of powder + (weight of device and powder - weight of devιce))/2 Anaesthesia
By an i v injection of Domitor® Vet inj (medetomidein 1 mg/ml), 0 15 ml/10 kg = 0 4 ml/pig, the pig is sedated
Immediately after, Rapmovet Vet inj (propofol 10 mg/ml) is injected slowly i v until sufficient depth of anaesthesia is obtained In general, 2-3 ml/10 kg is enough, but it may be necessary to supplement with 1-2 ml at a time until intubation is possible Atropin (1 mg/ml) is injected i m at 0 5 ml/pig and allowed to work mm 5 minutes before intubation
For intubation the pig is placed in ventral position with slightly elevated front, local anaesthetics Xylocaine® kutanspray (lidocain 10 mg/dosis) is sprayed onto the epiglottis, and the pigs are intubated using a laryngoscope and a disposable tube size 8 0 mm (ID) The two parts of the tube are pressed tightly together
Device position during pulmonal dosing
The position of the PennCentury™ device during dosing should be just outside the end of the endotracheal tube and this should be measured on the device before intubation (remember the connecting L-piece when measuring this) During dosing the tip of the PennCentury™ device should positioned in the trachea just below the bronchus that goes to lobus cranialis dexter, which is confirmed with the bronchoscope
Artificial respiration
The respiration frequency is set to 10/min and the respiration depth to 250 ml/breath. The respirator is mounted with "baby" bag to optimise timing of dosing The anaesthesia apparatus is connected to a filter that is connected to the endotracheal tube via a L-piece The PennCentury™ device is introduced through the L-piece, which will allow control over the respiration depth and frequency during dosing
Dosing technique The PennCentury™ device should be placed as described above The pigs are dosed (one at a time) with the PennCentury™ device by manual administration during inhalation using the adjustable PennCentury air pump (Model AP-1 ) Each pig is given 8 air sprays (air pump set to 4 mL) during 8 consecutive respirator-forced inhalations to ensure that the entire dose is given The chamber is gently tapped between sprays to avoid sticking of the powder to the device A new delivery tube is used for each pig The timing in relation to the inhalation is very important, and the air sprays should be given in the very beginning of the inhalation (aim for start at 50 mL inhalation)
To counteract the effect of Domitor, Antisedan® Vet inj (atipamezol 5 mg/ml) will be injected as an intramuscular injection (0.4 ml/pig) immediately after dosing, and the pigs will be taken back to their pens and allowed to wake up from anaesthesia
Retention analysis
The emitted dose should be the entire content of the chamber and after dosing the device is weighed again with any residual powder, and the retained powder is extracted with 9 ml of 0 01 N HCI med 0 05 % (w/v) Tween 80 extraction buffer and sent to analysis
Blood sampling
After the dosing, blood samples will be taken from a central venous catheter at the following time points
-10, 0, 10, 20, 40, 60, 90, 120, 150, 180, 240 (4 h), 300 (5 h), 360 (6 h), 8 h, 10 h, 12 h, 14 h, 16 h, 24 h, 32 h and 48 h
Samples are taken with a 3-way stop-cock, waste blood is injected back into the animal Sample size is: 0.8 ml of blood collected in a tube coated with EDTA After each blood sample the catheter is flushed with 5 ml of sterile 0 9 % NaCI with 10 IU/ml heparin The tube is tilted gently a minimum of 8 times to ensure sufficient mixing of blood and anticoagulant (EDTA) and after one minute it is placed on wet ice The tubes are spun for 10 mm at 3000 rpm and 40C within 1 hour after sampling The samples are stored on wet ice until pipetting
Closure of the catheters after the experiment
A single intravenous treatment with Ampicillin (10 mg/kg = 0 1 ml/kg of a 100mg/ml solution) dissolved in sterile saline (1 g Ampicillin in 10 ml = 100 mg/ml) is given via the catheter that has been used for blood sampling Both catheters are flushed with 4-5 ml of sterile 0 9 % NaCI added heparin to a concentration to 10 IU/ml The catheters are closed with a new luer-lock with latex injection membrane 4-5 ml sterile 0 9% NaCI is injected through the membrane Finally 0 8 ml of heparin, 5000 IU/ml, is injected through the catheter as a lock Aseptic technique is demanded to avoid bacterial growth in the catheter with increased risk of clotting
Analysis of blood samples
10 μl of plasma is pippetted into 500 μl of EBIO buffer solution for measurements of glucose concentration in plasma in the Biosen autoanalyser
Plasma samples are also assayed for exogenous insulin by immunoassays to calculate PK parameters Pulmonary dosing of the insulin of example 9 to mini-pigs according to the protocol above Figs 10 and 11 shows the pharmacokinetic profile of the insulin of example 9 compared to the same insulin but without the protease stabilising A14E and B25H mutations (insulin of prior art) The data are from the same experiment, Fig 10 is shown with the data from the first 250 minutes, and Fig 11 is shown with the full 24 hour (1440 minutes) time-course
Pharmacokinetic data for the insulin of example 9 compared to the same insulin but without the prote- ase stabilising A14E and B25H mutations (insulin of prior art) The data are from the same experiment, half-life (Ty2) and bioavailability (Flt) relative to intravenous administration

Rat pharmacokinecics:
Intravenous rat PK
Anaesthetized rats are dosed intravenously (/ v ) with insulin analogs at various doses and plasma concentrations of the employed compounds are measured using immunoassays or mass spectrometry at specified intervals for 4 hours or more post-dose Pharmacokinetic parameters are subsequently calculated using WinNonLin Professional (Pharsight lnc , Mountain View, CA, USA)
Non-fasted male Wistar rats (Taconic) weighing approximately 200 gram are used
Body weight is measured and rats are subsequently anaesthetized with Hypnorm/Dormicum (each compound is separately diluted 1 1 in sterile water and then mixed, prepared freshly on the experimental day). Aanaesthesia is initiated by 2 ml/kg Hypnorm/Doricum mixture sc followed by two maintenance doses of 1 ml/kg sc at 30 min intervals and two maintenance doses of 1 ml/kg sc with 45 min intervals. If required in order to keep the rats lightly anaesthetised throughout a further dose(s) 1-2 ml/kg sc is supplied. Weighing and initial anaesthesia is performed in the rat holding room in order to avoid stressing the animals by moving them from one room to another.
Peroral rat PK. Gavage:
Conscious rats are p.o dosed with insulin analogs Plasma concentrations of the employed com- pounds as well as changes in blood glucose are measured at specified intervals for 4-6 hours post- dosing. Pharmacokinetic parameters are subsequently calculated using WinNonLin Professional (Pharsight Inc., Mountain View, CA, USA)
Male Sprague-Dawley rats (Taconic), weighing 250-300 g are fasted for -18 h and p o dosed with test compound or vehicle
The composition of the formulation used for the oral qavaqe dosing is the following (in weight %): 45% Propylene glycol (Merck)
33% Capmul MCM C10 (Abitec) 11 % Poloxamer 407 (BASF)
11 % Polyethyleneglycol 3350 Ultra (Fluka)
The amount of added insulin is subtracted equaly from Capmul MCM C10, Poloxamer 407 and PEG 3350 and not from propylene glycol in order to keep the amount of propylene glycol independent of the drug load constant at 45%.
Neutral insulin (freeze-dried from pH 7.4) is dissolved in propylene glycol at RT under gentle agitation. Depending on the insulin and the amount of insulin it can take a few hours to dissolve in propylene glycol. The resulting solution should be clear. The other additives, Capmul, poloxamer and PEG3350 are mixed and melted together at 58 C and should also result in a clear, slightly yellowish solution. Then the insulin propylene glycol solution is warmed up to 35 0C and the melted additives are added portionwise under magnetic stirring. The resulting mixture should be clear and homogenously at 35 °C and results in a semi solid after storage in the fridge. After preparation the SEDDS composition is cooled down to 5 °C in order to solidify.
Blood samples for the determination of whole blood glucose concentrations are collected in hepaπ- nised 10 μl capillary tubes by puncture of the capillary vessels in the tail tip. Blood glucose concentrations are measured after dilution in 500 μl analysis buffer by the glucose oxidase method using a Bio- sen autoanalyzer (EKF Diagnostic Gmbh, Germany). Mean blood glucose concentration courses (mean ± SEM) are made for each compound.
Samples are collected for determination of the plasma insulin concentration. 100 μl blood samples are drawn into chilled tubes containing EDTA. The samples are kept on ice until centrifuged (7000 rpm, 4°C, 5 min), plasma is pipetted into Micronic tubes and then frozen at 200C until assay. Plasma concentrations of the insulin analogs are measured in the Assay and Technology dept. using an immunoassay which is considered appropriate or validated for the individual analog.
Blood samples are drawn at t=-10 (for blood glucose only), at t=-1 (just before dosing) and at specified intervals for 4-6 hours post-dosing
lntraintestinal injection:
Anaesthetized rats are dosed intraintestinally (into jejunum) with insulin analogs. Plasma concentrations of the employed compounds as well as changes in blood glucose are measured at specified ιn- tervals for 4 hours or more post-dosing Pharmacokinetic parameters are subsequently calculated using WinNonLin Professional (Pharsight Inc., Mountain View, CA, USA).
Male Sprague-Dawley rats (Taconic), weighing 250-300 g, fasted for —18 h are anesthetized using Hypnorm-Dormicum s.c (0 079 mg/ml fentanyl citrate, 2.5 mg/ml fluanisone and 1.25 mg/ml mida- zolam) 2 ml/kg as a priming dose (to timepoint -60 min prior to test substance dosing), 1 ml/kg after 20 min followed by 1 ml/kg every 40 min
The insulins to be tested in the intraintestinal injection model are formulated as formulated for the ga- vage model above
The anesthetized rat is placed on a homeothermic blanket stabilized at 37°C. A 20 cm polyethylene catheter mounted a 1-ml syringe is filled with insulin formulation or vehicle. A 4-5 cm midline incision is made in the abdominal wall. The catheter is gently inserted into mid-jejunum ~ 50 cm from the caecum by penetration of the intestinal wall. If intestinal content is present, the application site is moved ± 10 cm. The catheter tip is placed approx 2 cm inside the lumen of the intestinal segment and fixed without the use of ligatures. The intestines are carefully replaced in the abdominal cavity and the abdominal wall and skin are closed with autoclips in each layer. At time 0, the rats are dosed via the catheter, 0.4 ml/kg of test compound or vehicle
Blood samples for the determination of whole blood glucose concentrations are collected in hepari- nised 10 μl capillary tubes by puncture of the capillary vessels in the tail tip. Blood glucose concentrations are measured after dilution in 500 μl analysis buffer by the glucose oxidase method using a Bio- sen autoanalyzer (EKF Diagnostic Gmbh, Germany) Mean blood glucose concentration courses (mean ± SEM) are made for each compound Samples are collected for determination of the plasma insulin concentration. 100 μl blood samples are drawn into chilled tubes containing EDTA. The samples are kept on ice until centrifuged (7000 rpm, 4°C, 5 min), plasma is pipetted into Micronic tubes and then frozen at 20°C until assay. Plasma con- centrations of the insulin analogs are measured in a immunoassay which is considered appropriate or validated for the individual analog.
Blood samples are drawn at t=-10 (for blood glucose only), at t=-1 (just before dosing) and at specified intervals for 4 hours or more post-dosing.
