The invention relates to therapies by injection of insulin(s) for treating diabetes.
Insulin therapy, or therapy for diabetes by injection of insulin, has experienced remarkable progress over the past few years by virtue in particular of the development of new insulins which offer better correction of blood glucose level in patients in comparison with human insulin and which make it possible to simulate more closely the physiological activity of the pancreas.
When type II diabetes is diagnosed in a patient, a gradual treatment is put in place. The patient firstly takes oral antidiabetics (OADs) such as metformin. When OADs alone are no longer sufficient to regulate the glucose level in the blood, a change in the treatment must be made and, depending on the patients' specificities, various treatment combinations can be put in place. The patient can, for example, have a treatment based on a basal insulin of glargine or detemir type as a supplement to the OADs, then subsequently, depending on the progression of the disease, a treatment based on basal insulin and prandial insulin.
Moreover, today, in order to ensure the transition from treatments with OADs, when the latter are no longer able to control the glucose level in the blood, to a basal insulin/prandial insulin treatment, the injection of GLP-1 analogs is recommended.
GLPs-1, for Glucagon-Like Peptide-1, are insulinotropic peptides or incretins, and belong to the family of gut hormones which stimulate insulin secretion when the blood glucose level is too high, for example after a meal.
Gut hormones are also called satiating hormones. They comprise in particular GLP-1 (Glucagon like peptide-1) and GIP (Glucose-dependent insulinotropic peptide), oxyntomodulin (a proglucagon derivative), peptide YY, amylin, cholecystokinin, pancreatic polypeptide (PP), ghrelin and enterostatin which have peptide or protein structures. They also stimulate insulin secretion, in response to glucose and fatty acids, and are therefore in this respect potential candidates for the treatment of diabetes.
Among these gut hormones, GLPs-1 are those which have to date provided the best results in the development of medicaments. They have enabled patients suffering from type II diabetes to lose weight while at the same time having a better control of their blood glucose level.
GLP-1 analogs or derivatives have thus been developed, in particular for improving their stability.
To cover his daily insulin needs, a diabetic patient currently has, schematically, two types of insulins that have complementary actions: prandial insulins (or “fast-acting” insulins) and basal insulins (or “slow-acting” insulins).
The prandial insulins allow a rapid management (metabolization and/or storage) of the glucose taken in during meals and snacks. The patient must inject himself with a prandial insulin before each food intake, i.e. approximately 2 to 3 injections per day. The prandial insulins most widely used are: recombinant human insulin, NovoLog® (insulin aspart from NOVO NORDISK), Humalog® (insulin lispro from ELI LILLY) and Apidra® (insulin glulisine from SANOFI-AVENTIS).
The basal insulins maintain the glycemic homeostasis of the patient, outside periods of food intake. They act essentially to block the endogenous production of glucose (hepatic glucose). The daily dose of insulin generally corresponds to 40-50% of the total daily insulin needs. Depending on the basal insulin used, this dose is dispensed in 1 or 2 injections, spread out regularly over the course of the day. The basal insulins most widely used are Levemir® (insulin detemir from NOVO NORDISK) and Lantus® (insulin glargine from SANOFI-AVENTIS).
It will be noted, in the interest of being thorough, that NPH (insulin NPH for Neutral Protamine Hagedorn; Humuline NPH®, Insulatard®) is the oldest basal insulin. This formulation is the result of a precipitation of human insulin (anionic at neutral pH) using a cationic protein, protamine. The microcrystals thus formed are dispersed in an aqueous suspension and dissolve slowly after subcutaneous injection. This slow dissolution provides a prolonged release of the insulin. However, this release does not provide a constant concentration of insulin over time. The release profile is bell-shaped and only lasts between 12 and 16 hours. It is therefore injected twice a day. This NPH basal insulin is much less effective than the modern basal insulins, Levemir® and Lantus®. NPH is an intermediate-action basal insulin.
The principle of NPH has evolved with the appearance of the fast-acting insulin analogs to give products called “Premix” that offer both a fast action and an intermediate action. NovoLog Mix® (NOVO NORDISK) and Humalog Mix® (ELI LILLY) are formulations comprising a fast-acting insulin analog, Novolog® and Humalog®, partially complexed with protamine. These formulations thus contain insulin analog microcrystals, the action of which is termed intermediate, and an insulin component that has remained soluble, the action of which is fast. These formulations clearly offer the advantage of a fast-acting insulin, but they also have the defect of NPH, i.e. a limited duration of action of between 12 and 16 hours and an insulin with a “bell-shaped” release profile. However, these products allow patients to give themselves, in one go, an injection of an intermediate-action basal insulin with a fast-acting prandial insulin. As it happens, there are many patients who are anxious to reduce their number of injections.
The basal insulins currently marketed and currently in clinical development can be classified according to the technical solution which makes it possible to obtain the prolonged action, and, to date, two approaches are used.
The first approach, which is that of insulin detemir, is binding to albumin in vivo. Insulin detemir is an analog, which is soluble at pH 7, and which comprises a fatty acid (tetradecanoyl) side chain attached at position B29 which, in vivo, enables this insulin to associate with albumin. Its prolonged action is mainly due to this affinity for albumin after subcutaneous injection.
However, its pharmacokinetic profile does not make it possible to cover a day, which means that it is most commonly used as two injections per day.
Other basal insulins which are soluble at pH 7, such as Degludec®, are currently in development. Degludec® also comprises a fatty acid side chain attached to the insulin (hexadecanedioyl-γ-L-Glu).
The second approach, which is that of insulin glargine, is precipitation at physiological pH. Insulin glargine is a human insulin analog obtained by elongation of the C-terminal of the B chain of human insulin with two arginine residues, and by substitution of asparagine residue A21 with a glycine residue (U.S. Pat. No. 5,656,722). The addition of two arginine residues was considered in order to adjust the pI (isoelectric point) of insulin glargine at physiological pH, and thus to render this human insulin analog insoluble in physiological medium.
Also, the substitution of A21 was considered in order to render insulin glargine stable at acid pH and thus to be able to formulate it in the form of an injectable solution at acid pH. During subcutaneous injection, the passing of insulin glargine from an acid pH (pH 4-4.5) to a physiological pH (neutral pH) causes it to precipitate under the skin. The slow redissolution of the insulin glargine microparticles provides a slow and prolonged action.
The hypoglycemic effect of insulin glargine is virtually constant over a period of 24 hours, which enables most patients to limit themselves to a single injection per day.
Insulin glargine is today considered to be the best basal insulin on the market.
However, the necessarily acid pH of the formulations of basal insulins, the isoelectric point of which is between 5.8 and 8.5, of insulin glargine type, can be a real drawback since this acid pH of the insulin glargine formulation sometimes causes pain at the injection in patients and especially prevents any formulation with other proteins and in particular with prandial insulins, since the latter are not stable at acid pH. The impossibility of formulating a prandial insulin at acid pH comes from the fact that a prandial insulin undergoes, under these conditions, a side reaction consisting of deamidation in position A21, which does not make it possible to meet the requirement of the US pharmacopeia, namely less than 5% of by-products after 4 weeks at 30° C.
Thus, no one has to date sought to solubilize these basal insulins, of insulin glargine type, the isoelectric point of which is between 5.8 and 8.5, at neutral pH while at the same time maintaining a difference in solubility between the in vitro medium (the container) and the in vivo medium (under the skin), independently of the pH.
From the analysis of the compositions described in the literature and the patents, it appears that the insolubility at pH 7 of the basal insulins, of the insulin glargine type, is a prerequisite for having a slow action.
Indeed, the principle of how basal insulins, of insulin glargine type, the isoelectric point of which is between 5.8 and 8.5, function is that they are soluble at acid pH and precipitate at physiological pH. This diverts those skilled in the art from any solution in which the insulin of insulin glargine type would be solubilized at pH 6-8 while keeping its essential property which is that of precipitating in subcutaneous medium.
Furthermore, this acid pH of the formulations of basal insulins, the isoelectric point of which is between 5.8 and 8.5, of insulin glargine type, even prevents any extemporaneous combination with prandial insulins at neutral pH.
Indeed, a recent clinical study, presented at the 69th Scientific Sessions of the American Diabetes Association, New Orleans, La., Jun. 5-9, 2009, 0019-OR, made it possible to verify this limitation of the use of insulin glargine. A dose of insulin glargine and a dose of prandial insulin (in the case in point, insulin lispro) were mixed just before injection (E. Cengiz et al., 2010; Diabetes care—33(5): 1009-12). This experiment made it possible to demonstrate a significant delay in the pharmacokinetic and the pharmacodynamic profiles of the prandial insulin, possibly giving rise to postprandial hyperglycemia and to nocturnal hypoglycemia. This study clearly confirms the incompatibility of insulin glargine with the fast-acting insulins currently on the market.
Moreover, the instruction leaflet for Lantus®, the commercial product based on insulin glargine from the company SANOFI-AVENTIS, explicitly informs users not to mix with a solution of prandial insulin, whatever it may be, owing to the serious risk of modifying the pharmacokinetics and the pharmacodynamics of the insulin glargine and/or of the prandial insulin mixed together.
However, from a therapeutic point of view, it has been demonstrated, as illustrated hereinafter, that treatments combining either an insulin glargine and a prandial insulin, or an insulin glargine and a GLP-1 analog, are of real interest.
As regards the combination of an insulin glargine and a prandial insulin, clinical studies made public during the 70th annual scientific sessions of the American Diabetes Association (ADA) of 2010, abstract 2163-PO and abstract number 0001-LB, in particular those carried out by the company SANOFI-AVENTIS, showed that treatments which combine Lantus®, insulin glargine and a prandial insulin are much more effective than treatments based on products of the “Premix” type, Novolog Mix® or Humalog Mix®.
As regards the combination of an insulin glargine and a GLP-1 analog, the FDA (Food and Drug Administration) approved, in October 2011, the injection of exenatide (Byetta®, AMYLIN PHARMACEUTICALS, Inc and ELI LILLY and Company) as therapy supplementing insulin glargine for patients suffering from type II diabetes who are not able to achieve control of their blood glucose level with the basal insulin analog alone.
It so happens, owing to the fact that the very principle, set out above, of basal insulins, the isoelectric point of which is between 5.8 and 8.5, is that they are soluble at acid pH and precipitate at physiological pH, all the solutions proposed for combining them with other products, such as prandial insulins or GLP-1 analogs or derivatives, are based on tests for solubilization of the prandial insulins or GLP-1 analogs or derivatives at acid pH, see for example WO2007/121256, WO2009/021955, WO2011/144673, WO2011/147980 or else WO2009/063072.
For example, as regards the combinations of insulin glargine and fast-acting insulin, the company BIODEL has described, in particular in patent application U.S. Pat. No. 7,718,609, compositions comprising a basal insulin and a prandial insulin at a pH of between 3.0 and 4.2 in the presence of a chelating agent and of polyacids. This patent teaches how to make compatible a prandial insulin at acid pH in the presence of insulin glargine. It does not teach how to prepare a combination of insulin of insulin glargine type and of a prandial insulin at neutral pH.
Likewise by way of example, as regards the solubilization of insulin glargine at neutral pH and combinations with a GLP-1 analog, mention will be made of patent application WO2011/144676 published on Nov. 24, 2011, in the name of SANOFI-AVENTIS, which describes formulations, at pH 9.5, of insulin glargine with the cyclodextrin SVE4-β-CYD in which the solubility of insulin glargine is improved from 0.75 mM to 1.25 mM. This application also mentions compositions additionally comprising a GLP-1, although they are not exemplified. The solubilizing effect at pH 7.4 in a phosphate buffer is mentioned. These results of solubilization at pH 7.4 are described in the publication entitled “Effect of sulfobutyl ether-β-cyclodextrin on bioavailability of insulin glargine and blood glucose level after subcutaneous injection to rats” (International Journal of Pharmaceutics, 419 (2011), 71-76) in
To our knowledge, a formulation which is stable at physiological pH, comprising a basal insulin, the isoelectric point of which is between 5.8 and 8.5, alone or in combination with a prandial insulin and/or a gut hormone, in which the solubility of the insulin is sufficient for a therapeutic treatment, has therefore never been described.
The present invention, by solving this problem of solubility at a pH between 6.6 and 7.8, makes it possible:
Surprisingly, the compositions according to the invention the invention make it possible to solubilize, at a pH between 6.6 and 7.8, a basal insulin, the isoelectric point of which is between 5.8 and 8.5.
Surprisingly, the compositions according to the invention make it possible to maintain the duration of the hypoglycemic activity of the basal insulin, the isoelectric point of which is between 5.8 and 8.5, despite its solubilization at a pH of between 6.6 and 7.8 before injection. This notable property comes from the fact that the insulin of insulin glargine type solubilized at a pH of between 6.6 and 7.8 in the composition of the invention precipitates in subcutaneous medium through a change in composition of the medium. The element which triggers the precipitation of the insulin of insulin glargine type is no longer the pH modification, but a modification of the composition of the environment when the pharmaceutical composition passes from the container to the physiological medium. Surprisingly, in the combinations of insulin of insulin glargine type with a prandial insulin, which are subjects of the invention, the fast action of the prandial insulin is preserved despite the precipitation of the insulin of insulin glargine type in subcutaneous medium.
The solution as claimed in the invention making it possible to solubilize the basal insulin, the isoelectric point of which is between 5.8 and 8.5, at a pH of between 6.6 and 7.8, preserves its biological activity.
In the combinations of the insulin of insulin glargine type with a prandial insulin which are subjects of the invention, the fast action of the prandial insulin is preserved despite the precipitation of the insulin of insulin glargine type in subcutaneous medium. Furthermore, the presence of the prandial insulin does not modify the solubility of the basal insulin at a pH of between 6.6 and 7.8 and likewise does not modify the precipitation properties of the basal insulin.
The invention relates to a composition in the form of an injectable aqueous solution, the pH of which is between 6.6 and 7.8, comprising at least:

The anionic compounds bearing carboxylate charges and hydrophobic radicals according to formulae I, IV, V, IX, X and XI can be obtained by various synthesis routes, depending on whether they are in the isolated state or as a mixture.
The compounds can be obtained by random grafting of the carboxylate charges and/or hydrophobic radicals onto the saccharide backbone. Said compounds are then obtained in the form of a mixture.
In one embodiment, the anionic compounds bearing carboxylate charges and hydrophobic radicals are chosen from compounds of formulae I, IV, V, IX, X and XI, and they can be obtained by grafting of the carboxylate charges and/or hydrophobic radicals at precise positions on the saccharide units by means of a process which implements steps for protection/deprotection of the alcohol or carboxylic acid groups naturally borne by the backbone. This strategy results in selective, in particular, regioselective, grafting of the carboxylate charges and/or hydrophobic radicals onto the backbone. The protective groups include, without limitation, those described in the book Wuts, P G M et al., Greene's Protective Groups in Organic Synthesis 2007. Said compounds are then obtained in the isolated state.
The saccharide backbone can also be obtained by formation of glycosidic linkages between monosaccharide or oligosaccharide molecules using a chemical or enzymatic coupling strategy. The coupling strategies include those described in the publication Smoot, J T et al., Advances in Carbohydrate Chemistry and Biochemistry 2009, 62, 162-236 and in the book Lindhorst, T K, Essentials of Carbohydrate Chemistry and Biochemistry 2007, 157-208. The coupling reactions can be carried out in solution or on a solid support.
