Description
SPECIFICATION
Stable pharmaceutical preparation containing granulocyte colony stimulating factor and process for producing the same
The present invention relates to a pharmaceutical preparation containing a granulocyte colony stimulating factor. In particular, the present invention relates to a stabilized pharmaceutical preparation containing a granulocyte colony stimulating factor that is protected against loss or inacti vation of the active component (i.e., granulocyte colony stimulating factor) due to adsorption on the wall of a container in which the preparation is put, or to association, polymerization or oxidation of said component.
Chemotherapy has been undertaken as one method for treating a variety of infectious diseases but it has recently been found that chemotherapy causes some serious clinical problems such as the generation of drug-resistant organisms, change of causative organisms, and high side effects.
In order to avoid these problems associated with chemotherapy involving the use of therapeutic agents such as antibiotics and bactericides, attempts are being made to use a substance that activates the prophylactic capabilities of the host of an infection-causing organism and thereby providing a complete solution to the aforementioned problems of chemotherapy. Of the various prophylactic capabilities of the host, the phagocytic bactericidal action of leucocytes is believed to cause the strongest influence in the initial period of bacterial infection and it is therefore assumed to be important to enhance the infection protecting capabilities of the host by promoting the growth of neutrophiles and their differentiation into the mature state.A granulocyte colony stimulating factor (G-CSF) is one of the very useful substances that exhibit such actions and the same assignee of the present invention previously filed a patent application on an infection protecting agent using G-CSF (Japanese Patent Application No. 23777/1985).
As mentioned above, chemotherapy as currently practiced involves various unavoidable problems and intensive efforts are being made to use a drug substance that is capable of activating the prophylactic functions of the host or the person who has been infected.
Needless to say, G-CSF displays by itself the ability to activate the prophylactic functions of the host and it has also been found that G-CSF exhibits greater therapeutic effects in clinical applications if it is used in combination with a substance that activates the prophylactic capabilities of the host.
G-CSF is used in a very small amount and a pharmaceutical preparation containing 0.1-500 ,ug (preferably 5-50 ug) of G-CSF is usually administered at a dose rate of 1-7 times a week per adult. However, G-CSF has a tendency to be adsorbed on the wall of its container such as an ampule for injection or a syringe. Therefore, if the drug is used as an injection in such a form as an aqueous solution, it will be adsorbed on the wall of its container such as an ampule or a syringe. This either results in the failure of G-CSF to fully exhibit its activity as a pharmaceutical agent or necessitates the incorporation of G-CSF in a more-than-necessary amount making allowance for its possible loss due to adsorption.
In addition, G-CSF is labile and highly susceptible to environmental factors such as temperature, humidity, oxygen and ultraviolet rays. By the agency of such factors, G-CSF undergoes physical or chemical changes such as association, polymerization and oxidation and suffers a great loss in activity. These phenomenon make it difficult to ensure complete accomplishment of a therapeutic act by administering a very small amount of G-CSF in a very exact manner.
It is therefore necessary to develop a stable pharmaceutical preparation of G-CSF that is fully protected against a drop in the activity of its effective component. This is the principal object of the present invention which provides a stable pharmaceutical preparation of G-CSF.
The present inventors conducted intensive studies in order to enhance the stability of a G-CSF containing pharmaceutical preparation and found that this object can effectively be attained by addition of a pharmaceutically acceptable surfactant, saccharide, protein or high-molecular weight compound.
Therefore, the stable G-CSF containing pharmaceutical preparation of the present invention is characterized by containing both G-CSF and at least one substance selected from the group of a pharmaceutically acceptable surfactant, saccharide, protein and high-molecular weight compound.
The G-CSF to be contained in the pharmaceutical preparation of the present invention can be obtained by any of the methods such as those described in the specifications of Japanese
Patent Application Nos. 153273/1984, 269455/1985, 269456/1985, 270838/1985 and 270839/1985. For example, a human G-CSF can be prepared either by cultivating a cell strain (CNCM Accession Number 1-315 or 1-483) collected from tumor cells of patients with oral cavity cancer, or by expressing a recombinant DNA (which has been prepared by the agency of a human G-CSF encoding gene) in an appropriate host cell (e.g. E. coli, C 127 cell or ovary cells of a Chinese hamster).
Any human G-CSF that has been purified to high degree may be employed as the G-CSF to be contained in the pharmaceutical preparation of the present invention. Preferable human G-CSFs are ones obtained by isolation from the supernatant of the culture of a human G-CSF producing cell, and a polypeptide or glycoprotein having the human G-CSF activity that is obtained by transforming a host with a recombinant vector having incorporated therein a gene coding for a polypeptide having the human G-CSF activity.
Two particularly preferable examples of human G-CSF are shown below:
(1) human G-CSF having the following physicochemical properties:
i) molecular weight: about 19,000 + 1,000 as measured by electrophoresis through a sodium dodecylsulfate-polyacrylamide gel;
ii) isoelectric point: having at least one of the three isoelectric points, pl = 5.5 + 0.1, pl = 5.8 + 0.1, and pl = 6.1 + 0.1;
iii) ultraviolet absorption: having a maximum absorption at 280 nm and a minimum absorption at 250 nm;
iv) amino acid sequence of the 21 residues from N terminus: H2N-Thr-Pro-Leu-Gly-Pro-Ala-Ser- Ser-Leu-Pro-Gln-Ser-Phe-Leu-Leu-Lys-Cys-Leu-Glu-GIn-Val (2) human G-CSF containing either a polypeptide having the human granulocyte stimulating factor activity which is represented by all or part of the amino acid sequence shown below, or a glycoprotein having both said polypeptide and a sugar chain portion:: (Met)nThr Pro Leu Gly Pro Ala Ser Ser Leu Pro Gln Ser Phe Leu Leu Lys Cys Leu Glu Gln Val

(provided that m is 0 or 1; and n is 0 or 1).
For details of the method for preparing these two types of G-CSF, see the specification of
Japanese Patent Application Nos. 153273/1984, 269455/1985, 269456/1985, 270838/1985
and 270839/1985, all having been filed by the assignee of the present invention.
Another method that can be employed consists of performing fusion of a G-CSF producing cell
with a self-proliferating maiignant tumor cell and cultivating the resulting hybridoma in the
presence or absence of mytogen.
The human G-CSF containing solution obtained may be stored in a frozen state after being further purified and concentrated, as required, by any known technique. Alternatively, the solu tion may be stored after being dehydrated by such means as freeze-drying.

Needless to say, these high-molecular weight compounds may be used either alone or in combination.
The high-molecular weight compounds listed above are desirably used in amounts of 1-20,000 parts by weight per part by weight of G-CSF.
In addition to the surfactant, saccharide, protein or high-molecular weight compound described above, at least one member selected from the group consisting of an amino acid, a sulfureous reducing agent and an antioxidant may also be incorporated in making the G-CSF containing pharmaceutical preparation of the present invention.

The above-listed amino acids, sulfureous reducing agents and antioxidants or mixtures thereof are preferably used in amounts of 1-10,000 parts by weight per part by weight of G-CSF.
For the purpose of formulating the stable G-CSF containing preparation of the present invention in a suitable dosage form, one or more the following agents may be incorporated: a diluent, a solubilizing aid, an isotonic agent, an excipient, a pH modifier, a soothing agent, and a buffer.
The stabilized G-CSF pharmaceutical preparation of the present invention may be formulated either for oral administration or for parenteral administration such as by injection applied in various ways, and a variety of dosage forms may be employed depending upon the specific mode of administration. Typical dosage forms include: those intended for oral administration such as tablets, pills, capsules, granules and suspensions; solutions, suspensions and freezedried preparations principally intended for intravenous injection, intramuscular injection, subcutaneous injection and intracutaneous injection; and those intended for transmucosal administration such as rectal suppositories, nasal drugs, and vaginal suppositories.
According to the present invention, at least one substance- selected from the group consisting of a surfactant, a saccharide, a protein or a high-molecular weight compound is added to a G
CSF containing pharmaceutical preparation so that it is prevented from being adsorbed on the wall of its container or a syringe while at the same time, it remains stable over a prolonged period of time.
The detailed mechanism by which the substances mentioned above stabilized G-CSF or prevent it from being adsorbed is yet to be clarified. In the presence of a surfactant, the surface of G
CSF which is a hydrophobic protein would be covered with the surfactant to become solubilized so that the G-CSF present in a trace amount is effectively prevented from being adsorbed on the wall of its container or a syringe. A saccharide or hydrophilic high-molecular weight compound would form a hydrated layer between G-CSF and the adsorptive surface of the wall of its container or a syringe, thereby preventing adsorption of G-CSF in an effective manner. A protein would compete with G-CSF for adsorption on the wall of its container or a syringe, thereby effectively inhibiting adsorption of G-CSF.
Besides the prevention of G-CSF adsorption, the substances mentioned above would also contribute to the prevention of association or polymerization of the molecules of G-CSF. In the presence of a surfactant, saccharide, protein or high-molecular weight compound, the individual molecules of G-CSF are dispersed in these substances and the interaction between the G-CSF molecules is sufficiently reduced to cause a significant decrease in the probability of their association or polymerization. In addition, these substances would retard the autoxidation of G
CSF that is accelerated under high temperature or humidity or prevent G-CSF from being associated or polymerized as a result of its autoxidation.These effects of retarding autoxidation of G
CSF or preventing it from being associated or polymerized would be further enhanced by addition of an amino acid, a sulfureous reducing agent or an antioxidant.
The problems described above are particularly noticeable in solutions for injection and in suspensions but they also occur during the process of formulating G-CSF in other dosage forms such as tablets. The addition of surfactants, saccharides, proteins or high-molecular weight compounds is also effective in this latter case.
Through the addition of at least one substance selected from the group consisting of a surfactant, saccharide, protein and a high-molecular weight compound, G-CSF is highly stabilized and maintains its activity for a prolonged period of time, as will be demonstrated in the examples that follow. To attain these results, the amount of each of these substances, in particular its lower limit, is critical and the following ranges are desirable: 1-10,000 parts by weight of surfactant, 1-10,000 parts by weight of saccharide, 1-20,000 parts by weight of protein, and 1-20,000 parts by weight of high-molecular weight compound, per 1 part by weight of G-CSF.
According to the present invention, a surfactant, a saccharide, a protein and/or a highmolecular weight compound is used in a specified concentration and this is effective not only in preventing G-CSF from being adsorbed on the wall of its container or a syringe but also in enhancing the stability of a G-CSF containing pharmaceutical preparation. As a result, it becomes possible to ensure the administration of a small but highly precise dose of G-CSF to patients; since G-CSF is costly, its efficient utilization will lead to lower costs for the production of G-CSF containing pharmaceutical preparations.
The following examples are provided for the purpose of further illustrating the present invention but are in no sense to be taken as limiting. In these examples, the residual activity of G-CSF was determined by one of the following methods.
(a) Soft agar method using mouse bone marrow cells:
A horse serum (0.4 ml), 0.1 ml of the sample, 0.1 ml of a C3H/He (female) mouse bone marrow cell suspension (0.5 -1 X > c 105 nuclear cells), and 0.4 ml of a modified McCoy's 5A culture solution containing 0.75% of agar were mixed, poured into a plastic dish for tissue culture (35 mm3, coagulated, and cultured for 5 days at 37"C in 5% CO2/95% air and at 100% humidity. The number of colonies formed was counted (one colony consisting of at least 50 cells) and the activity was determined with one unit being the activity for forming one colony.
The modified McCoy's 5A culture solution used in the method (a) was prepared by the following procedures.
Modified McCoy's 5A culture solution (double concentration)
Twelve grams of McCoy's 5A culture solution (Gibco), 2.55 g of MEM amino acid-vitamin medium (Nissui Seiyaku Co., Ltd.), 2.18 g of sodium bicarbonate and 50,000 units of potassium penicillin G were dissolved twice in 500 ml of distilled water and the solution was aseptically filtered through a Millipore filter (0.22 yam).
(b) Reverse-phase high-performance liquid chromatography:
Using a reverse-phase C8 column (4.6 mm x 300 mm; 5 ,umì and an n-propanol/trifluoroacetic acid mixture as a mobile phase, the residual activity of G-CSF (injected in an amount equivalent to 1 CIS) was determined under the following gradient conditions:
Time (sec) Solvent (A) Solvent (B) Gradient
0 100% 0% 15 0% 100% linear 15 0% 100% linear 25 100% 0% Solvent (A): 30% n-propanol and 0.1% trifluoroacetic acid
Solvent (B): 60% n-propanol and 0.10/0 trifluoroacetic acid
Detection was conducted at a wavelength of 210 nm and the percentage of the residual G
CSF activity was calculated by the following formula:
the residual amount of G-CSF
Residual G-CSF - after the lapse of a given time activity (%) - the initial amount of G-CSF x lO0 The residual amount of G-CSF as determined by this method correlated very well with the
result attained in measurement by the soft agar method (a) using mouse bone marrow cells.
Example 1
To 5,ug of G-CSF, one of the stabilizing agents listed in Table 1 was added and the mixture was aseptically dissolved in a 20 mM buffer solution (containing 100 mM sodium chloride; pH
7.4) to make a pharmaceutical preparation containing 5 ,ug of G-CSF per ml, which was then freezer-dried. The time-ciependent change in G-CSF activity was measured by method (a) and the
results are shown in Table 1.The term "activity (%)" in the table represents the residual activity
of G-CSF relative to the initial unit and is defined by the following formula:
activity unit after Activity (t ~ the lapse of a given time x 100
initial activity unit Freeze-drying was conducted by the following procedures:
