Description
NOVEL USE OF INSULIN DERIVATIVES
FIELD OF THIS INVENTION
This invention relates to insulin derivatives having an extremely long duration of action. Said derivatives can be used to treat diabetes and aspects related thereto. In a preferred aspect, these derivatives are only administered around once weekly to the patients.
BACKGROUND OF THIS INVENTION
Insulin is a polypeptide hormone secreted by β-cells of the pancreas. Insulin consists of two polypeptide chains designated the A and B chains which are linked together by two inter-chain disulphide bridges. In human, porcine and bovine insulin, the A and B chains contains 21 and 30 amino acid residues, respectively. However, from species to species, there are variations among the amino acid residues present in the different positions in the two chains. The widespread use of genetic engineering has made it possible to prepare analogues of natural occurring insulins by exchanging, deleting and adding one of more of the amino acid residues.
Insulin is used for the treatment of diabetes and diseases connected therewith or resulting from it. Insulin is essential in maintaining normal metabolic regulation. Usually, insulin is administered by injections (subcutaneously). Unfortunately, many diabetics are unwilling to undertake intensive therapy due to the discomfort associated with the many injections required to maintain close control of blood glucose levels. In the last decades, it has turned out that it is extremely important for a diabetic patient to maintain close control of the blood glucose level.
For decades, insulin preparations with different duration of action have been developed and put on the market and general examples of such preparations are long-acting insulin preparations, medium acting insulin preparations and fast acting insulin preparations. Many patients take 2-4 injections per day. For example, before a meal, many patients take a fast acting insulin preparation which shall control the glucose level after the meal, such treatments being designated prandial treatment. However, in order to control the glucose level at other moments than close to the moments of eating, diabetics have to take an insulin preparation with a longer duration of action, e.g., before they go to sleep, and this can be designated basal treatment. Hence, many diabetics take one injection every evening before they go to sleep. Even though such insulin preparations are effective in controlling the glucose level for about one night and day, they are not sufficient for controlling the glucose level for more than one night and day. No basal insulin products are approved for other than
daily subcutaneous injection. The discomfort of a large number of daily injections can, for example, be diminished by using insulin derivatives having an extremely long duration of action.
Claim 1 in WO 2010/049488 mentions "administering ... effective dosages of the insulin derivative ... said dosages are administered at intervals longer than 24 hours".
According to the abstract in J. Controlled Release 104 (2005), 447-60, "When doses [of PEGylated human insulin encapsulated in PLGA] were given [to animals] at 7-day intervals, steady state drug levels were achieved after only 2 doses". Claim 25 in WO 98/05361 mentions "A method wherein ... effective doses of N-(Fmoc)2-insulin and N-(Fmoc)3-insulin are administered to the patient at 5-8 day intervals". In example 107 of WO 201 1/161 125, it is mentioned that acylated insulin derivatives of the invention (insulin derivatives having two or more cysteine substitutions to allow for one or more additional disulphide bonds) are administered to rats, plasma is collected at time points 0-96 hours after dosing and the plasma is assayed for glucose. WO 2009/1 15469 relates to acylated insulin analogues, that are able to give a satisfactory control of the blood glucose level following once daily administration, see page 2 line 15.
It is very desirable for the diabetics, if insulin preparations which are to be administered only say about once weekly and which would give a satisfactory basal treatment were available.
In 2007, there were 246 million diabetics in the world. In 2025, the number is expected to be about 380 million.

DEFINITIONS
As defined herein, the term "diabetes" or "diabetes mellitus" includes type 1 diabetes, type 2 diabetes, gestational diabetes (during pregnancy) and other states that cause hyperglycaemia. The term is used for a metabolic disorder in which the pancreas produces insufficient amounts of insulin, or in which the cells of the body fail to respond appropriately to insulin thus preventing cells from absorbing glucose. As a result, glucose builds up in the blood.
Type 1 diabetes, also called insulin-dependent diabetes mellitus (IDDM) and juvenile-onset diabetes, is caused by B-cell destruction, usually leading to absolute insulin deficiency.

DETAILED DESCRIPTION OF THIS INVENTION
Human insulin consists of two polypeptide chains, interconnected by two cystine disulphide bridges. The primary amino acid sequence for the human insulin A chain (21 amino acids) is n-G I V E Q C C T S I C S L Y Q L E N Y C N-c (SEQ ID NO: 1 ). The primary amino acid sequence for the human insulin B chain (30 amino acids) is n-F V N Q H L C G D H L V E A L Y L V C G E R G F F Y T P K T-c (SEQ ID NO: 2).
It has, surprisingly, been found that insulin derivatives having the general formula I:
Acy-X-Yn-lns, have an extremely long duration of action. The insulin derivatives of formula I have a so retarded duration of action that, to many patients, it can be used as the only insulin product for basal administration and that it is sufficient to administer it only about once weekly. In formula I, "Ins" designates an analogue of human insulin, to which insulin analogue a side chain (designated Acy-X-Yn-) has been attached to the ε amino group present in the B29 lysine amino acid in said insulin analogue. In other words, "Ins" designates an insulin analogue as herein defined; and, according to formula I, a side chain (designated Acy-X-Yn-) has been attached to said insulin analogue, i.e., attached to the ε amino group present in the B29 lysine amino acid in said insulin analogue. Said insulin analogue is human insulin containing glutamic acid in the A14 position, histidine in the B25
position, optionally histidine in the B16 position and, optionally, the B27 and/or B30 amino acid(s) has/have been removed. In said side chain having the general formula II (and designated Acy-X-Yn-), Acy is a fatty diacid with 8-24 carbon atoms from which a hydroxyl group has been removed, X is yGlu wherein the amino residue has been connected to "Acy" and - if n is different from zero - the carbonyl group in yGlu has been connected to Y or - if n is zero - the gamma- (γ) carbonyl group in yGlu has been connected to the ε amino group in lysine in the B29 position in the insulin analogue, Y is -NH-(CH2)2-0-(CH2)2-0-CH2-CO- wherein the amino residue is connected to X and the carbonyl group is connected to the ε amino group in lysine in the B29 position in the insulin analogue, and n is 0 (zero), 1 , 2 or 3. Hence, this invention relates to insulin derivatives having the general formula I: Acy-X-Yn-lns, wherein Ins designates an insulin analogue and a side chain (designated Acy-X-Yn-) has been attached to the ε amino group present in the B29 lysine amino acid in said insulin analogue, said insulin analogue is human insulin containing glutamic acid in the A14 position, histidine in the B25 position, optionally histidine in the B16 position and, optionally, the B27 and/or B30 amino acid(s) has/have been removed, Acy is a fatty diacid with 8-24 carbon atoms from which a hydroxyl group has been removed, X is yGlu wherein the amino residue has been connected to "Acy" and - if n is different from zero - the carbonyl group in yGlu has been connected to Y or - if n is zero - the gamma-(Y) carbonyl group in yGlu has been connected to the ε amino group in lysine in the B29 position in the insulin analogue, Y is -NH- (CH2)2-0-(CH2)2-0-CH2-CO- wherein the amino residue is connected to X and the carbonyl group is connected to the ε amino group in lysine in the B29 position in the insulin analogue, and n is 0 (zero), 1 , 2 or 3.
A specific example of such an insulin derivative of formula I is A14E, B16H, B25H, B29K(N£-eicosanedioyl-YGIu-[2-(2-{2-[2-(2-aminoethoxy)ethoxy]acetylamino}ethoxy)ethoxy]- acetyl), desB30 human insulin (herein designated Compound 1 ). This compound can also be designated A14E, B16H, B25H, B29K(NE-eicosandioyl-YGIu-OEG-OEG), desB30 human insulin, or alternatively A14E, B16H, B25H, B29K(NE-eicosandioyl-YGIu-2xOEG), desB30 human insulin, and has the following formula:

The above compound is mentioned in example 33 in WO 2009/115469.
Examples of other specific insulin derivatives of formula I are A14E, B16H, B25H, B29K(N£-hexadecandioyl-YGIu), desB30 human insulin (herein designated Compound 2); A14E, B16H, B25H, B29K(N£-eicosanedioyl-YGIu), desB30 human insulin (herein designated Compound 3); A14E, B25H, desB27, B29K(N£-(octadecandioyl-YGIu), desB30 human insulin (herein designated Compound 4); A14E, B25H, desB27, B29K(/\f-octadecanedioyl-YGIu- OEG-OEG), desB30 human insulin (herein designated Compound 5); and A14E, B25H, B29K(/\f-octadecandioyl-yGlu-OEG-OEG), desB30 human insulin (herein designated Compound 6). The formulae of the five last-mentioned compounds are stated in examples 27, 60, 151 , 57 and 9, respectively, in WO 2009/115469.
Some of the compounds of formula I are known compounds and the remaining compounds of formula I can be prepared in a manner known perse, e.g., as analogously as described in WO 2009/115469.
Biophysics studies show that Compound 1 has different behaviour than ordinary insulin molecules and, similarly, this is expected to apply for the other insulin derivatives of formula I.
The in vivo potency of Compound 1 in pigs and dogs was estimated to be approximately 200% relative to insulin glargine.
In vivo pharmacology of Compound 1 in pigs has shown that dosing of a 4.2 mM solution, the absolute bioavailability is 90% relative to intravenously administration of the same compound.
Pharmaceutical formulations containing an insulin derivative of formula I can be prepared in a manner known perse, i.e., by using the additives usually used in similar insulin formulations.
The insulin formulations are administered to the patients in a manner known per se, e.g., according to the general knowledge of the patient combined with the general knowledge of the physician. This invention is best used at the convenience of the patient. Therefore, specific administration intervals will be explored for each patient where dosages are administered less than daily. The final mode of use thus depends both on the product's capabilities and on the disposition and preference of the patient. This is due to the fact that the effect of any insulin product depends on the insulin need of the individual patient and the sensitivity to the pharmacodynamic actions of said insulin and lastly also to the preferences of the patient in a given situation. These conditions may change over time, both in terms of longer periods (years) and from day to day. The optimal dose level for any patient will depend on a variety of factors including 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 dosage regimen be determined for each individual patient by those skilled in the art in a similar way as for known insulin formulations, however taking into consideration the present teachings concerning dosage intervals.
For the convenience of the patients, it is presumed that they prefer that the time interval (time lag) from the administration of one derivative of formula I to the next administration of a derivative of formula I has the same length, or approximately the same length, counted in number of days. It can even be expected that the patients will prefer that the administration of a derivative of formula I takes place only once weekly, i.e., on the same day in the week, e.g. on every sunday. This will be an administration of a derivative of formula I every 7th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. For some patients, it may be desirable to administer a derivative of formula I every 6th day or approximately every 6th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. For other patients, it may be desirable to administer a derivative of formula I every 5th day or approximately every 5th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. For other patients, it may be desirable to administer a derivative of formula I every 4th day or approximately every 4th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. Even other patients may find it advantageous to administer a derivative of formula I only twice weekly, e.g., with an interval of about 3-4 days between each administration and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. For some patients, it may be desirable to administer a derivative of formula I every 3rd day or approximately every 3rd day and not more frequently on an average calculated for a period of
time of 1 month, 6 months or 1 year. For other patients, it may be desirable to administer a derivative of formula I every 2nd day or approximately every 2nd day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. For some patients, it may be desirable to administer a derivative of formula I every 8th day or approximately every 8th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. Even other patients may not administer the derivative of formula I with a time interval of precisely the same length (counted in days), week after week, month after month or year after year. Some patients may administer a derivative of formula I sometime in the time interval from every 6th to every 8th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. Other patients may administer a derivative of formula I sometime in the time interval from every 5th to every 7th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. Even other patients may administer a derivative of formula I sometime in the time interval from every 4th to every 8th day and not more frequently on an average calculated for a period of time of 1 month, 6 months or 1 year. The time intervals mentioned here are to be understood as average time intervals within a period of time of say weeks, months or years. Here, it is intended that the term "day" covers 24 hours (i.e., a day and night) and, for the sake of easiness, a number of hours which is not divisible by 24 is to be rounded up to a whole number of days. Hence, e.g., 30 hours corresponds to 1 day and 40 hours corresponds to 2 days. Obviously, the above intervals of administration are to be calculated for each person.
The patients may have a daily basal insulin requirement of above about 0.2 lU/kg/day and below about 1 lU/kg/day and, furthermore, the patients may have a total (i.e., basal plus prandial) daily insulin requirement of above about 1 lU/kg/day. However, these ranges may vary considerably from patient to patient and may for several patients be somewhat outside the ranges mentioned here.
Diseases and conditions which are the primary targets for this invention are diabetes mellitus (type 1 or 2) or other conditions characterized by hyperglycaemia, but also metabolic diseases and conditions in general where the metabolic effects of insulin has a clinical relevance or are of interest, such as pre-diabetes, impaired glucose tolerance, metabolic syndrome, obesity, cachexia, in vivo beta-cell loss/death, excessive appetite, and
inflammation. All these types of conditions are known to or believed to benefit from a stable metabolic state in the subject who has the disease or condition. At any rate, any therapeutic regimen where administration of insulin is included may be modified by implementing the
current teachings, meaning that such therapies will include administration of prolonged- profile-of -action insulins according to the teachings provided herein.
In order to exercise this invention, an insulin preparation may be administered parenterally to patients in need of such a treatment. Parenteral administration may be performed by subcutaneous, intramuscular or intravenous injection by means of a syringe, optionally a pen-like syringe. Alternatively, parenteral administration can be performed by means of an infusion pump. Further options are to administer the insulin composition nasally or pulmonary, preferably in compositions, powders or liquids, specifically designed for the purpose.
Embodiments of the method of this invention include those wherein administration of an insulin derivative of formula I is supplemented with more frequent administrations of a fast-acting naturally occurring insulin, insulin analogue or insulin derivative and/or
administration of a non-insulin anti-diabetic drug. In one embodiment of this invention, administration of an insulin derivative of formula I is supplemented with administration of a non-insulin anti-diabetic drug, such as metformin.

Example 1
Effect of subcutaneously administered insulin analogue of the invention on blood glucose, C-peptide, and HbA1 c versus NPH insulin and vehicle in Sprague Dawley rats
Rats were allowed free access to food and water prior to the experiment. At time 0 min, 200 μΙ_ tongue blood was drawn. The rats (groups of 6 animals) were injected either with vehicle, NPH insulin (12 nmol/animal), and A14E, B16H, B25H, B29K(N£-eicosanedioyl- YGIu-[2-(2-{2-[2-(2-aminoethoxy)ethoxy]acetylamino}ethoxy)ethoxy]acetyl), desB30 human insulin (Compound 1 ) (50, 100, and 200 nmol/animal) s.c in the neck skin. At following time points, blood samples were drawn: 2, 4, 6, 8, 24, 32, 48, 72, and 96 hours. Blood samples were analysed for insulin exposure, C-peptide, plasma glucose, and HbA1 c (HbA1 c only 96 h time point). The results are presented in Figures 1 -4:
Fig. 1 shows the plasma concentration levels following dosing of 3 different doses of Compound 1 (50, 100 and 200 nmol/animal) to rats within the time interval of 1-4 days.
Fig. 2 shows the blood glucose levels following dosing of NPH insulin (12
nmol/animal), of 3 different doses of Compound 1 (50, 100, and 200 nmol/animal) and of vehicle to rats within the time interval of 1-4 days.
Fig. 3 shows the C-peptide levels following dosing of NPH insulin (12 nmol/animal) and of 3 different doses of Compound 1 (50, 100, and 200 nmol/animal) to rats within the time interval of 1-4 days.
Fig. 4 shows the level of HbA1 c 4 days after administration of NPH insulin (12 nmol/animal) and of 3 different doses of Compound 1 (50, 100, and 200 nmol/animal) to rats 4 days after administration.
The conclusion from these figures is that one single dosing of Compound 1 to normal non-diabetic rats is enough to:
• Lower blood glucose for 2-3 days
· Lower C-peptide for at least 4 days
• Significantly lower HbA1 c in non-diabetic rats.
The importance of the data given for the compound of this invention is illustrated by comparison with the data for the NPH insulin which is, generally, considered a long-acting preparation.
Example 2
Pharmacokinetic profiles after intravenously (i.v.) dosing were made in Beagle dogs (weighing approximately 12 kg) to evaluate the pharmacokinetic properties of insulin degludec (Insulin degludec is a once-daily basal insulin analogue with an ultra-long duration of action described in e.g. WO 2005/012347), and to evaluate the pharmacokinetic properties of a compound of formula 1 , i.e., A14E, B16H, B25H, B29K(N£-eicosanedioyl-YGIu-[2-(2-{2- [2-(2-aminoethoxy)ethoxy]acetylamino}ethoxy)ethoxy]acetyl), desB30 human insulin
(Compound 1 ). It was also desirable to be able to calculate the bioavailability after extravascular dosing. The animals were dosed i.v., 1 .0 or 1.6 nmol/kg of insulin degludec or Compound 1 , respectively, blood samples were collected and plasma analysed using sandwich immunoassay.
Pharmacokinetic profiles after subcutaneous (s.c.) profile were made in Beagle dogs (approximately 12 kg), to evaluate the pharmacokinetic properties after s.c. dosing. 4.1 or 17 nmol/kg of insulin degludec or Compound 1 , respectively, were injected subcutaneously.
Blood samples were drawn and the plasma concentration of insulin degludec and of Compound 1 , respectively, were measured.
All studies were single dose studies. The calculations were performed using the software WinNonlin Professional 5.3 (Pharsight Inc., Mountain View, CA, USA). The data obtained are presented in Tables 1 -2 below.
As can be deduced from the data obtained from MRT after s.c. dosing (7.7 hours versus 92 hours), it indicates that in dog the duration of action of Compound 1 is at least 7 times longer than the duration of action of insulin degludec, which in turn has been shown to be a true once daily insulin in humans.

weekly to humans with similar flat steady state plasma concentration profile as insulin degludec injected every day.
The simulation was performed using the software WinNonlin Professional 5.3 (Pharsight Inc., Mountain View, CA, USA). A simple one compartment model with first order elimination and absorption rate was used to simulate insulin degludec dosing once daily (every 24 hour) and Compound 6, dosing once daily (every 24 hour) and in addition twice weekly (every 84 h). Average pharmacokinetic parameters from human studies were used for insulin degludec (absorption rate constant = 0.031 h"1 and elimination rate constant = 0.25 h"1 corresponding to absorption half-life of 22 hours and elimination half-life of 2.8 hours). For Compound 6, average parameters from human studies were used for the elimination rate constant, but as the absorption rate constant after subcutaneous dosing was not known for humans, the absorption rate constant for insulin degludec was used instead (elimination rate constant = 0.013 h"1 corresponding to elimination half-life of 52 hours).
From the simulated steady state levels of both insulin analogues the maximum plasma concentration and the minimum plasma concentration achieved from plasma concentration vs time profiles was recorded. The fluctuation at steady state was then calculated as the maximum plasma concentration divided by the minimum plasma concentration.
The fluctuations were estimated to be:
Based on simulated results, Compound 6 given once daily would be expected to provide a more flat plasma concentration vs time profile than that insulin degludec as judged by the lowering in fluctuations rate. Also, Compound 6 injected twice weekly would be expected to give the same fluctuations in the plasma concentration profile as that of insulin degludec once daily based on similar fluctuation rates.
A14E, B25H, desB27, B29K(N£-(octadecandioyl-YGIu), desB30 human insulin
(Compound 4) has been shown to have almost the same terminal half-life, and thus similar elimination rates, in humans as Compound 6. Also, A14E, B25H, desB27, Β29Κ(ΛΓ- octadecanedioyl-yGlu-2xOEG), desB30 human insulin (Compound 5) is expected to show
the same terminal half-life as that of Compound 6 in man (as the elimination half-lives are very similar to that of Compound 6 in dogs). Therefore a flat steady state plasma concentration profile with lower fluctuations than that of insulin degludec should be expected for these insulin analogues.
