Definitions

  • a stabilized pharmaceutical formulation comprising a growth hormone and Lys-X
  • the present invention relates to a stabilized pharmaceutical formulation comprising growth hormone, to a method of making such formulation, and the use of Lys-X, wherein X designates an amino acid residue, for stabilizing a formulation of growth hormone.
  • the growth hormones from man and from the common domestic animals are proteins of approximately 191 amino acids, synthesized and secreted from the anterior lope of the pituitary gland. Human growth hormone consists of 191 amino acids.
  • Growth hormone is a key hormone involved in the regulation of not only somatic growth, but also in the regulation of metabolism of proteins, carbohydrates and lipids. The major effect of growth hormone is to promote growth.
  • the organ systems affected by growth hormone include the skeleton, connective tissue, muscles, and viscera such as liver, intestine, and kidneys.
  • human growth hormone could only be obtained by extraction from the pituitary glands of human cadavers.
  • the very limited supplies of growth hormone restricted the use thereof to longitudinal growth promotion in childhood and puberty for treatment of dwarfism, even though it has been proposed for inter alia treatment of short stature (due to growth hormone deficiency, normal short stature and Turner syndrome), growth hormone deficiency in adults, infertility, treatment of burns, wound healing, dystrophy, bone knitting, osteoporosis, diffuse gastric bleeding, and pseudoarthrosis.
  • growth hormone has been proposed for increasing the rate of growth of domestic animals or for decreasing the proportion of fat in animals to be slaughtered for human consumption.
  • compositions of growth hormone tend to be unstable.
  • Degradation products such as deamidated or sulfoxydated products and dimer or polymer forms are generated - especially in solutions of growth hormone.
  • the predominant degradation reactions of hGH are 1) deamidation by direct hydro ⁇ lysis or via a cyclic succinimide intermeadiate to form various amounts of L-asp- hGH, L-iso-asp-hGH, D-asp-hGH, and D-iso-asp-hGH (ref 1-3), and 2) oxidation of the methionine residues in positions 14 and 125 (ref 4-9).
  • the major degradation product of hGH in lyophilized state as well as in solution is deamidated hGH.
  • Deamidation especially takes place at the Asn in position 149 and to a minor extent in position 152 and 99.
  • hGH is also rather easily oxidized in positions 14 and 125, especially in solution (4- 8).
  • the oxidation of hGH in solution forming sulfoxides is normally due to the oxygen dissolved in the formulation.
  • the solubility of oxygen in distilled water is about 200 ⁇ M (9).
  • concentration of hGH in a formulation comprising 4 IU/ml is 1.3 mg/ml corresponding to 60nM hGH, oxygen will, at normal storing conditions, be present in an excess of about 3000 times the stoichiometric amount for oxidation of hGH. It is not feasible to try to solve the problem by degassing of buffers before tapping and packing the formulations.
  • the kinetics of degradation depend on temperature, pH and various additives or adjuvants in the hGH formulation.
  • growth hormone Due to the instability, growth hormone is, at present, lyophilized and stored in the lyophilized form at 4°C until it is reconstituted for use in order to minimize the degradation.
  • the lyophilized pharmaceutical formulations comprising hGH are, at present, recon ⁇ stituted by the patient and then stored as a solution during the use for a period of up to 14 days at 4°C, during which some degradation will take place.
  • the growth hormone as late as possible before use and to store and ship the formulation in a lyophilized state.
  • the chain from the manufacturer to the pharmacy is apt for handling the formulations at a controlled low temperature of e.g. 4°C which allows for a long shelf life of up to two years.
  • a formulation which is stable for a sufficient long time with the end user under conditions where "sufficient" cooling is not always available.
  • a formulation should be stable with the end user in a lyophilized state for about one month and additionally for one month in a reconstituted state in a pen device for the intended period of use of a cartridge.
  • the shift in pattern of administration of growth hormone to the use of pen devices calls for a stable dissolved formulation comprising growth hormone in order to facilitate the handling to be performed by the patient.
  • a stable dissolved formulation comprising growth hormone may be produced ready to use in the form of cartridges fitting into the pen device used by the patient who may then avoid the reconstitution of the formulation and, hence, will not have to be in the possession of a lyophilized formulation, a suitable vehicle for reconstitution as well as the necessary skill and sterile equipment for sterile reconstitution of the formulation.
  • Lyophilization is a time consuming and costly process and is also often a "bottleneck" in the production due to the limited capacity of the freeze drier.
  • animal growth hormone may be stabilized with various stabilizers to give decreased formation of insolubles and preservation of the soluble activity in aqueous environments, such stabilizers including certain polyols, amino acids, polymers of amino acids having a charged side group at physiological pH, and choline salts.
  • Polyols are selected from the group consisting of non-reducing sugars, sugar alcohols, sugar acids, pentaerythritol, lactose, water-soluble dextrans and Ficoll; amino acids are selected from the group consisting of glycine, sarcosine, lysine or salts thereof, serine, arginine or salts thereof, betaine, N,N,-dimethyl-glycine, aspartic acid or salts thereof, glutamic acid or salts thereof; a polymer of an amino acid having a charged side group at physiological pH may be selected from polylysine, polyaspartic acid, polyglutamic acid, polyarginine, polyhistidine, polyornithine and salts thereof; and choline derivatives are selected from the group consisting of choline chloride, choline dihydrogen citrate, choline bitartrate, choline bicarbonate, tricholine citrate, choline ascorbate, choline borate, choline

  • Published European patent application No. 374,120 discloses a stabilized formulation comprising hGH and a polyol having three hydroxy groups. Glycerol and tris(hydroxymethyl)aminomethane are mentioned. Furthermore, the presence of histidine hydrochloride as a buffer together with the polyol is disclosed.
  • WO 93/19776 discloses protein formulations comprising growth hormone comprising citrate as buffer substance being more stable than formulations comprising phosphate buffer.

Abstract

Un composition pharmaceutique, qui comprend une hormone de croissance et Lys-X, où X désigne un résidu d'acide aminé, ainsi qu'un additif ou une substance de tamponnage, procure une très forte stabilité contre la déamidation, l'oxydation et la coupure des liaisons peptidiques. La stabilité du produit permet son entreposage et son expédition à l'état lyophilisé ou comme formulation dissoute ou re-dissoute à la température ambiante.
