Protein stabilization in solution
Provided are storage containers for proteinaceous pharmaceutical compositions which are characterized in, among other things, comprising (i) a wall portion, wherein an inner wall material thereof is selected from silica-coated glass, silicone-coated glass, polymers of non-cyclic olefins, cycloolefin polymers and cycloolefin/linear olefin copolymers and (ii) one or more closure portions not constituting part of the wall portion, and which contains a formulation of a protein. Also provided are new methods of storing proteinaceous compositions. In one aspect, the stored protein is characterized as having an amino-terminal γ-carboxyglutamic acid (Gla) domain with 9-12 Gla residues.
1. A storage container for a pharmaceutical formulation of a protein, wherein said protein is a human factor VII protein, a factor VII-related polypeptide, or an activated form thereof, having an amino-terminal γ-carboxyglutamic acid (Gla) domain with 9-12 Gla residues comprising:
a. a wall portion and one or more closure portions not constituting part of the wall portion, the wall portion comprising an inner surface that, along with the one or more closure portions, defines an interior chamber;
b. a composition in the interior chamber, the composition comprising the pharmaceutical formulation of the protein,
wherein the inner surface of the wall portion comprises Type I glass as defined in the 4th edition of the European Pharmacopeia (Ph. Eur.) coated with a 1% silicone oil emulsion, and
wherein the 1% silicone oil emulsion forms a coating on said Type I glass, said coating having a substantially uniform thickness of 0.005 micrometers to 10 micrometers, and
wherein the coating reduces the tendency of said protein to undergo dimerization, oligomerization and/or polymerization.
2. The container of claim 1 , wherein the container is in the form of a vial or a cartridge comprising a needle-penetrable, self-sealing elastomeric septum.
3. The container of claim 2 , wherein the container is a cartridge further comprising a displaceable piston whereby, upon operation thereof, liquid present in the container may be expelled from the container.
4. The container of claim 1 , wherein the pharmaceutical formulation is a liquid aqueous formulation comprising the protein.
5. The container of claim 4 , wherein the aqueous formulation has a pH of about 3 to about 8.
6. The container of claim 5 , wherein the aqueous formulation has a pH of about 5.5 to about 6.5.
7. The container of claim 1 , wherein the pharmaceutical formulation is a substantially solid formulation suitable for dissolution in water or an aqueous vehicle.
8. A storage container for a pharmaceutical formulation of a protein, wherein said protein is a human factor VII protein, a factor VII-related polypeptide, or an activated form thereof, having an amino-terminal γ-carboxyglutamic acid (Gla) domain with 9-12 Gla residues comprising:
a. a wall portion and one or more closure portions not constituting part of the wall portion, the wall portion having an inner surface that along with the one or more closure portions defines an interior chamber, wherein the inner surface is manufactured from cycloolefin polymer material which, when incubated for at least 24 months in contact with water or an aqueous solution having a pH of from about 3 to about 8 at a temperature of 40° C. or less, releases about 3 μM or less of at least one trivalent metal ion into solution; and
b. the pharmaceutical formulation of the protein.
9. The container of claim 8 , wherein the trivalent metal ion is Al 3+ .
10. The container of claim 8 , wherein the material, when incubated for at least 24 months in contact with water or an aqueous solution having a pH of from about 3 to about 8 at a temperature of 40° C. or less, releases about 3 μM or less of at least one divalent metal ion into solution.
11. The container of claim 10 , wherein the divalent metal ion is Zn 2+ .
12. A method of storing a formulation comprising a protein, wherein said protein is a human factor VII protein, a factor VII-related polypeptide, or an activated form thereof, having an amino-terminal γ-carboxyglutamic acid (Gla) domain with 9-12 Gla residues, the method comprising the steps of:
a. obtaining a container comprising an inner wall surface made from Type I glass as defined in the 4th edition of the European Pharmacopeia (Ph. Eur.) coated with a 1% silicone oil emulsion to form a coating on the glass, wherein the coating has a substantially uniform thickness of 0.005 micrometers to 10 micrometers;
b. at least partially filling the container with the formulation comprising the protein;
c. closing the container with a closure in order to store the formulation, and
d. reducing the tendency of said protein to undergo dimerization, oligomerization and/or polymerization.
13. A method of storing a formulation comprising a protein, wherein said protein is a human factor VII protein, a factor VII-related polypeptide, or an activated form thereof, having an amino-terminal γ-carboxyglutamic acid (Gla) domain with 9-12 Gla residues, the method comprising the steps of:
a. obtaining a container comprising an inner wall wherein the inner wall is manufactured from cycloolefin polymer which, when incubated for at least 24 months in contact with water or an aqueous solution having a pH of from about 3 to about 8 at a temperature of 40° C. or less, releases about 3 μM or less of at least one trivalent metal ion into solution;
b. at least partially filling the container with the formulation of the protein; and
c. closing the container with a closure in order to store the formulation.
