Summary for Patent: 10,286,045
Title:Subcutaneous therapeutic enzyme formulations, uses, and methods for generating thereof
Abstract: Provided herein are compositions containing a lysosomal storage disorder replacement enzyme (LSDRE) and a dispersing agent for subcutaneous injection for treatment of lysosomal storage diseases. Kits and methods of treatment are also provided.
Inventor(s): Cao; Mingju (Pomona, CA), Cao; Alexander M. (Pomona, CA)
Assignee: KINETIQ, INC. (Claremont, CA)
Application Number:15/959,195
Patent Claims:1. A composition administered via subcutaneous or intradermal delivery used to treat a lysosomal storage disease (LSD) comprising: a lysosomal storage disorder replacement enzyme (LSDRE) and a dispersing agent in a stable formulation, wherein the dispersing agent is in an amount corresponding to less than 1000 U per single unit dose for facilitating subcutaneous or intradermal delivery of a therapeutically effective amount of LSDRE, and wherein the amount of dispersing agent is limited to ensure that the LSDRE is delivered throughout the body not including the brain or bone.

2. The composition of claim 1, wherein LSDRE is alpha-galactosidase A (GLA) or beta-glucocerebrosidase.

3. The composition of claim 1, wherein the dispersing agent is selected from a group consisting of hyaluronidase, collagenase, elastase, chonroitinase, and combinations thereof.

4. The composition of claim 3, wherein the hyaluronidase is selected from a group consisting of animal-derived hyaluronidase and recombinantly-produced hyaluronidase.

5. The composition of claim 1, wherein the stable formulation is aqueous and is stable for at least 3 months when stored at 2-8.degree. C.

6. The composition of claim 1, wherein the stable formulation is lyophilized and is stable for at least 6 months when stored at 2-8.degree. C.

7. The composition of claim 1, wherein the LSDRE maintains at least 50% of its activity during storage.

8. The composition of claim 1, wherein the LSDRE is in an amount of about 1 mg to about 100 mg.

9. The composition of claim 1, wherein the lysosomal storage disease (LSD) is selected from the group consisting of Fabry disease, Gaucher disease, Pompe disease, Tay-Sachs disease, Sandhoff disease, Niemann-Pick disease, Krabbe disease, Farber disease, metachromatic leukodystrophy, MPS I (Hurler, Scheie, Hurler-Scheie), Hunter disease, MPS III (A, B, C, D), MPS IV (A, B), Maroteaux-Lamy disease, Sly disease, alpha mannosidosis, beta mannosidosis, fucosidosis, Schindler disease (I, II, Ill), Wolman, aspartylglucosaminuria, prosaposin deficiency, sulfatide activator deficiency, and Gaucher activator deficiency.

10. The composition of claim 1, wherein the dispersing agent is in an amount corresponding to 100 to less than 1000 U, 250 to less than 1000 U, 1-5 U, 5-10 U, 10-50 U, 50-100 U, 100-200 U, 200-300 U, 300-500 U or 500 to less than 1000 U per single unit dose.

11. The composition of claim 1, wherein the composition is a multi-dose formulation.

12. The composition of claim 1, wherein the composition is packaged in a prefilled syringe.

13. The composition of claim 12, wherein syringe comprises a first chamber and a second chamber, wherein the first chamber comprises a lyophilized form of the composition, and the second chamber comprises a pharmaceutically acceptable diluent for reconstitution of the composition.

14. A method of treating a lysosomal storage disease (LSD) in a patient in need thereof comprising, administering subcutaneously or intradermally a composition of claim 1.

15. The method of claim 14, wherein the lysosomal storage disease (LSD) is selected from the group consisting of Fabry disease, Gaucher disease, Pompe disease, Tay-Sachs disease, Sandhoff disease, Niemann-Pick disease, Krabbe disease, Farber disease, metachromatic leukodystrophy, MPS I Hurler syndrome, Scheie syndrome, Hurler-Scheie syndrome, Hunter disease, MPS III type A, type B, type C, or type D, MPS IV type A or type B, Maroteaux-Lamy disease, Sly disease, alpha mannosidosis, beta mannosidosis, fucosidosis, Schindler disease type I, type II or type III, Wolman, aspartylglucosaminuria, prosaposin deficiency, sulfatide activator deficiency, Gaucher activator deficiency.

16. The method of claim 14, wherein the administering is subcutaneously or intradermally with a unit dose at a frequency selected from the group consisting of three times a day, twice a day, once a day, every other day, every three days, every four days, every five days, every six days, every week, and every two weeks.

17. The method of claim 16, wherein the unit dose is no more than 1.5 mL.

18. The method of claim 14, wherein the LSDRE is alpha-galactosidase A-, whereby the treatment dosage is between 0.05-3.0 mg/kg.

19. The method of claim 14, wherein the LSDRE is beta-glucocerebrosidase, whereby the treatment dosage is between 0.05-130 U/kg.
