Description
1 32~5~2 IN LO~ IONIC STRE~GTH ~EDIA
This invention relates to stable factor VIII
formulations More particularly, high purity factor VIII
protein is formulated in low ionic strength media for administration to patients suffering from hemophilia type A.
Antihemophilic factor or factor VIII procoagulation activity protein (hereinafter factor VIII) functions to correct the clotting defect in hemophilic type A plasma.
~ccordingly, factor VIII preparations are extensively used for the purpose of supplying factor VIII to hemophilic patients.
An important concern associated with the use of factor VIII and other therapeutic agents derived from biological sources is the transmission of diseasesl especially viral diseases. Prevalent viral contaminants include hepatitis B virus (HBV), non-A, non-B hepatitis virus (NANBV), and HTLV III/LA~/~IV which cauCe AIDS. In order to ensure that products produced from biological sources are virus-safe, various methodologies have been proposed for virus inactivation. However, most plasma protein preparations are unstable and require special care to prevent denaturation, alteration and loss of activity during the virus inactivation process. One approach to prevent denaturation and other alteration of plasma proteins utilizes additives during the pasteurization process. Representative examples followO
'' USP No. 4,440,679 (Fernandes et al.) describes a method wherein therapeutically active proteins are ., ~ -2- 1 329~2 pasteurized by mixing the protein composltion with a pasteurization-stabilizing amount of a polyol prior to pasteurization.
USP ~o. 4,297,344 (Schwinn et al.) discloses a process for the stabilization against heat of the coagulation factors II, VIII, XIII, antithrombin III and plasminogen in aqueous solution, which comprises adding to the solution both an aminoacid and one or more of a monosaccharide, an oligosaccharide or a sugar alcohol. ;
USP No. 4,585,654 (Landaburu et al.) pertains to a process of inactivating viruses in plasma protein solutions by heating the same in the presence of a polyol, a surface active agent and a chelating agent.
USP No. 4,446,134 (~aito et al.) is drawn to a virus-inactivating process in which factor VIII is heated in -~an aqueous solution in the presence of one principal stabilizer of neutral amino acids, monosaccharides, oligosaccharides, and sugar alcohols and an aw~iliary stabilizer of salts of hydrocarbon and hydroxyhydrocarbon carboxylic acids.
These processes aim at destroying the potential viral and bacterial infectivity of the preparations while substantially maintaining their desired biological activity.
As such, they represent significant steps toward the provision of satisfactory plasma protein products to patients.
In order to be administrable/ the plasma protein products need to be formulated with suitable compounds lyophilized for storage and ready for reconstitution, Before formulating, the additives used during the pasteurization process are removed and their stabilizing/prote~ting effect ,~ -3-t 3295~
l is no longer present to prevent loss of activity. Applicants have encountered degradation problems with factor VIII both during lyophilization and upon reconstitution with normal saline solution. To eliminate the effects of residual stabilizing agents and/or other materials used in the prior art during the production or pasteurization, a highly purified factor VIII was used to study degradation occurring during lyophilization and reconstitution such as that produced by the teaching of USP No. 4,361,509. The method there disclosed provides for about one thousand-fold purification of factor VIII obtained from a commercial concentrate using an anti-body column. The subsequent purification step by an A~,inohexyl-Sepharose column chromatography further increases purity by 2 to 3-fold l resulting in factor VIII activity of over 2,000 units per mg of protein.
Elution of factor VIII from the Aminohexyl-Sepharose is accomplished by the use of calcium chloride solution having a concentration of from 0.25 to 0.5M. This solution, having such high concentration of calcium chloride is not suitable for injection to the patient. More importantly, upon lyophilization, a drastic loss of factor VIII was observed.
To remedy the problems, an isotonic solution was prepared by dialyzing factor VIII contained in said calcium chloride solution against 0.15M sodium chloride, 5mM calcium chloride and 3mM histidine at pH 6.8. Upon testing, a drastic loss of factor VIII was again observed.
It has now been discovered that factor VIII as well 3 as other plasma and recombinant proteins, can be formulated -~ -4-1 32q5~
1 with physiologically acceptable compounds for stabilization against loss of activity during lyophilization, storage in the lyophilized state and reconstitution preceding administration to patients.
In accordance with the present invention plasma and recombinant pro~ein formulations are provided which are stable, and upon reconstitution, are ready for administration into patients. The formulations comprise at least one particular protein as the active ingredient for therapeutic use and a low ionic strength medium. The amount of protein present in a formulation is based on its kno~m activity against the ailments to be treated and ~7ill vary from protein to protein, their concentration and state of purity.
The low ionic strength medium is an aqueous solution of and comprises:
~ a) from about 0.5mM to about 15mM sodium chloride or potassium chloride or mixtures thereof and preferably about 1.5mM sodium chloride;
(b) from about O.OlmM to about lOmM and preferably about 0.20 to 2.OmM lysine hydrochloride; and (c) from about 0.2mM to about 5mM and preferably about 0.5 to l.OmM histidine as buffer ion.
The pH of the media should be from about 6.0 to about 7.6 and preferably about 7Ø
The present invention is also directed to a composition for stabilizing from about 2 ml to about 2000 ml of an aqueous solution of a lyophilized plasma protein comprising:
from about 0.058 mg to about 1754 mg sodium 30 chloride, from about 0.074 mg to about 2237 mg potassium chloride or mistures thereof;
~ 5_ 1 3295~2 l from about 0.0036 mg to about 3653 mg lysine hydrochloride; and from about 0.062 mg to about 1552 mg histidine.
Optionally, up to about 10% w/v of sugars, such as mannitol, sucrose and maltose, may be added to the formulations of the present invention for lyophilization.
The addition of maltose ~10~), sucrose (10~) or mannitol (5~) makes the formulated factor VIII solution isotonic. ~ -The formulation is lyophilized and stored in that state. Prior to use it is reconstituted with water to the volume present before lyophilization.
The formulations containing 10 to 500 units of factor VIII per ml of solution have been found effective for the treatment of hemophilia.
The present invention encompasses proteinaceous materials and products in the biomedical field intended for use in the human or animal body for biomedical or therapeutic purposes as well as non-therapeutic experimental purposes.

These methods as well as other techniques are summarized in "The Plasma Proteins", second edition, Vol. III, pp. 548-550, Academic Press, New York, NY (1977).
While the invention is applicable to these and other similar products and materials, it will be described in detail in reference to factor VIII procoagulant activity protein produced according to USP No. 4,361,509. The method therein disclosed is capable of producing highly purified and concentratad factor VIII which is effective in the treatment of hemophilia, having more than two thousand units of factor VIII procoagulant activity per mg of protein. However, the product as obtained by the process is unstable during lyophilization and upon reconstitution. Furthermore, the high calcium ion solution containing the factor is 3 undesirable for administration to the patients. The following examples and tests will further illustrate the invention.
, 1 3~95~2 Example 1 The rate of factor VIII degradation under isotonic conditions was studied. Factor VIII, obta:ined by the process of USP No. 4,361,509, in buffered 500 mr~ calcium chloride solution was dialyzed against lM sodium ch:Loride, 0.035 M
calcium chloride and 3mM histidine at pH 6 8, for salt e~change, and then was lyophilized. Reconsti~ution of the lyophilized material was made to 0.167 ~ sodium chloride, 5.8 mM calcium chloride, and 3 mM histidine by adding a 6-fold volume of 2.5 mM histidine, at pH 6.8, over the pre-lyophilization volume. The time dependent decay of factor VIII activity was determined by the two stage assay method which is essentially the same as the method described by Newman, J., Johnson, A. J., Karpatkin, S. and Puszkin, S.
(1971), Br. J. Haematol. 21, pp. 1-20. The results are shown in Table I.

Example 2 1 kg of frozen human plasma cryoprecipitate was placed in 2.8 kg of 0.05M glycine and 0.038M sodium chloride.
The mixture was placed in a 37C water bath and agitated under laminar flow of air to form a suspension of the cryoprecipitate. 0.1 N acetic acid was added dropwise to the suspension to bring the pH to 6.0 ~0.1. One hundred grams of ~Rehsorptar (2~ aluminum hydroxide gel, Armour Pharmaceutical Company, Kankakee, Illinois) were added to the mixture to adsorb vitamin K-dependent blood coagulation factors and agitated for 15 to 20 minutes at 35 to 37C. The suspension was centrifuged at 4,000 x g at room temperature for 15 minutes and the supernatant was collected. The Rehsorptar treatment was repeated one more time.
3.113 kg of this solution (18,297 units of Factor VIII), was applied to an affinity column (13.7 cm x 22.0 cm, 3.24 1) of monoclonal anti-von Willebrand antibody gel matrix, which was previously prepared by conjugation of 1.2 g of the antibody per 1 of Sepharose gel. The column was then washed with 3 column volumes of the Factor VIII buffer.
Nineteen percent ~3,537 units) of the Factor VIII were not bound to the column. The column was eluted with 0.25M
calcium chloride in the Factor VIII buffer. The Factor VIII
activity containing portion, 3.556 kg (9,880 units), was collected. The eluted Factor VIII was applied on to an Aminohexyl-Sepharose column (2.5 cm x 5.6 cm, Pharmacia) immediately after a five-fold in-line dilution with the AH-Sepharose equilibration buffer ~ZOmM histidine, lOOmM
3 lysine hydrochloride, pH 6.8). The flow rate was 12 ml per minute.
1 32q5~2 There was no detectable Factor VIII activity in the solution that passed through the AH-Sepharose column. The column was washed with 209 g of somM calcium chloride in the AH-Sepharose equilibration bu~fer. A sma~l amount of Factor VIII activity (165 units, 1.7%) was detected in the wash buffer solution collected. The Factor VIII was then eluted ~rom the column with 500mM calcium chloricle in the AH-Sepharose equilibration buffer. The peak fraction of the elution profile contained 6,890 units of Factor VIII in 26.5 g. The eluted Factor VIII was dialyzed overnight at 4C
against the buffer solution composed of lM sodium chloride, 5mM calcium chloride, 3mM histidine, 2% mannitol, pH 7Ø
The dialyzed Factor VIII had 266 u/ml and 23 g.
The Factor VIII solution was redialyzed at ~C
against a low ionic strength formulation buffer composed of 1.5mM sodium chloride, 0.2mM lysine hydrochloride, 0.2mM
histidine, pH 7Ø The redialyzed Factor VIII solution had 299 units per ml. Maltose was added to make the Factor VIII
solution 10% in maltose, which is isotonic, and lyophilized.
Reconstitution of the lyophilized material was made to its original volume with water for injection. Reconstitution was immediate.
Activity of Factox VIII was measured by the two stage method referred to in ~xample 1. The results are shown in Table II.

These products and materials are available from various commercial sources or can be produced by using well-known preparative techniques. For example, blood fractions and blood proteins can be obtained from human blood plasma by fractionation according to known techniques such as, for example, the alcohol fractionation of Cohn described in USP No. 2,390,074 and the Journal of the American Chemical society Vol. 68, p. 459 (1946). These methods as well as other techniques are summarized in "The Plasma Proteins", second edition, Vol. III, pp. 548-550, Academic Press, New York, NY (1977).
While the invention is applicable to these and other similar products and materials, it will be described in detail in reference to factor VIII procoagulant activity protein produced according to USP No. 4,361,509. The method therein disclosed is capable of producing highly purified and concentratad factor VIII which is effective in the treatment of hemophilia, having more than two thousand units of factor VIII procoagulant activity per mg of protein. However, the product as obtained by the process is unstable during lyophilization and upon reconstitution. Furthermore, the high calcium ion solution containing the factor is 3 undesirable for administration to the patients. The following examples and tests will further illustrate the invention.
, 1 3~95~2 Example 1 The rate of factor VIII degradation under isotonic conditions was studied. Factor VIII, obta:ined by the process of USP No. 4,361,509, in buffered 500 mr~ calcium chloride solution was dialyzed against lM sodium ch:Loride, 0.035 M
calcium chloride and 3mM histidine at pH 6 8, for salt e~change, and then was lyophilized. Reconsti~ution of the lyophilized material was made to 0.167 ~ sodium chloride, 5.8 mM calcium chloride, and 3 mM histidine by adding a 6-fold volume of 2.5 mM histidine, at pH 6.8, over the pre-lyophilization volume. The time dependent decay of factor VIII activity was determined by the two stage assay method which is essentially the same as the method described by Newman, J., Johnson, A. J., Karpatkin, S. and Puszkin, S.
(1971), Br. J. Haematol. 21, pp. 1-20. The results are shown in Table I.

Example 2 1 kg of frozen human plasma cryoprecipitate was placed in 2.8 kg of 0.05M glycine and 0.038M sodium chloride.
The mixture was placed in a 37C water bath and agitated under laminar flow of air to form a suspension of the cryoprecipitate. 0.1 N acetic acid was added dropwise to the suspension to bring the pH to 6.0 ~0.1. One hundred grams of ~Rehsorptar (2~ aluminum hydroxide gel, Armour Pharmaceutical Company, Kankakee, Illinois) were added to the mixture to adsorb vitamin K-dependent blood coagulation factors and agitated for 15 to 20 minutes at 35 to 37C. The suspension was centrifuged at 4,000 x g at room temperature for 15 minutes and the supernatant was collected. The Rehsorptar treatment was repeated one more time.
3.113 kg of this solution (18,297 units of Factor VIII), was applied to an affinity column (13.7 cm x 22.0 cm, 3.24 1) of monoclonal anti-von Willebrand antibody gel matrix, which was previously prepared by conjugation of 1.2 g of the antibody per 1 of Sepharose gel. The column was then washed with 3 column volumes of the Factor VIII buffer.
Nineteen percent ~3,537 units) of the Factor VIII were not bound to the column. The column was eluted with 0.25M
calcium chloride in the Factor VIII buffer. The Factor VIII
activity containing portion, 3.556 kg (9,880 units), was collected. The eluted Factor VIII was applied on to an Aminohexyl-Sepharose column (2.5 cm x 5.6 cm, Pharmacia) immediately after a five-fold in-line dilution with the AH-Sepharose equilibration buffer ~ZOmM histidine, lOOmM
3 lysine hydrochloride, pH 6.8). The flow rate was 12 ml per minute.
1 32q5~2 There was no detectable Factor VIII activity in the solution that passed through the AH-Sepharose column. The column was washed with 209 g of somM calcium chloride in the AH-Sepharose equilibration bu~fer. A sma~l amount of Factor VIII activity (165 units, 1.7%) was detected in the wash buffer solution collected. The Factor VIII was then eluted ~rom the column with 500mM calcium chloricle in the AH-Sepharose equilibration buffer. The peak fraction of the elution profile contained 6,890 units of Factor VIII in 26.5 g. The eluted Factor VIII was dialyzed overnight at 4C
against the buffer solution composed of lM sodium chloride, 5mM calcium chloride, 3mM histidine, 2% mannitol, pH 7Ø
The dialyzed Factor VIII had 266 u/ml and 23 g.
The Factor VIII solution was redialyzed at ~C
against a low ionic strength formulation buffer composed of 1.5mM sodium chloride, 0.2mM lysine hydrochloride, 0.2mM
histidine, pH 7Ø The redialyzed Factor VIII solution had 299 units per ml. Maltose was added to make the Factor VIII
solution 10% in maltose, which is isotonic, and lyophilized.
Reconstitution of the lyophilized material was made to its original volume with water for injection. Reconstitution was immediate.
Activity of Factox VIII was measured by the two stage method referred to in ~xample 1. The results are shown in Table II.
