Description

SUBCUTANEOUS ADMINISTRATION OF ADAMTS13 CROSS-REFERENCES TO RELATED APPLICATIONS This application claims priority to US. Provisional Patent Application Serial Nos. 61/794,659 filed March 15, 2013, the disclosure of which is hereby incorporated herein by reference in its ty for all purposes.
BACKGROUND OF THE INVENTION The ADAMTS (a disintegrin and metalloproteinase with thrombospondin type I motifs) proteins are a family of metalloproteinases containing number of conserved domains, ing a zinc-dependant catalytic domain, a cystein-rich domain, a disintegrin-like domain, and at least one, and in most cases multiple, ospondin type I repeats (for review, see Nicholson et al., BMC Evol Biol. 2005 Feb. 4; 5(1): 1 1). These proteins, which are evolutionarily related to the ADAM and MMP es of metalloproteinases (Jones G C, Curr Pharm Biotechnol. 2006 ry ;7(1):25-31), are secreted enzymes that have been linked to a number of diseases and conditions including thrombotic ocytopenic purpura (TTP) (Moake J L, Semin Hematol. 2004 January ;41(1):4-14), connective tissue disorders, cancers, inflammation (Nicholson et al.), and severe plasmodium falciparum malaria (Larkin et al., PLoS Pathog. 2009 March ;5(3):e1000349). Because of these associations, the ADAMTS enzymes have been recognized as potential therapeutic targets for a number of pathologies (Jones G C, Curr Pharm Biotechnol. 2006 February;7(1):25-31).
One ADAMTS family member, ADAMTSl3, cleaves von Willebrand factor (vWF) between residues Tyr 1605 and Met 1606. Loss ofADAMTSl3 activity has been linked to a number of conditions, such as TTP (Moake J L, Semin l. 2004 y ;41(1):4-14), acute and chronic inflammation (Chauhan et al., J Exp Med. 2008 Sep. 1 ;205(9):2065-74), and most recently, severe plasmodium arum malaria (Larkin et al., PLoS Pathog. 2009 March;5(3):e1000349).
Thrombotic ocytopenic a (TTP) is a disorder characterized by thrombotic microangiopathy, thrombocytopenia and microvascular thrombosis that can cause 2014/026747 various degrees of tissue ischemia and infarction. Clinically, TTP patients are diagnosed by symptoms such as thrombocytopenia, schistocytes ents of erythrocytes) and elevated levels of lactate dehydrogenase (Moake J L. otic microangiopathies. N Engl J Med. 2002 ; 347:5 89-600; Moake J L. von Willebrand factor, ADAMTS-l3, and thrombotic thrombocytopenic purpura. Semin l. 2004 ; 41:4-14; Sadler J E, Moake J L, Miyata T, George J N. Recent advances in thrombotic thrombocytopenic purpura. Hematology (Am Soc Hematol Educ Program). 2004 : 407-423; Sadler J E. New concepts in von Willebrand disease.
Annu Rev Med. 2005; 56:173-l9l).
There are two major types of TTP: acquired (noninherited/idopathic) and familial (inherited) (Tsai H M, Lian E C. Antibodies to von Willebrand factor-cleaving protease in acute thrombotic thrombocytopenic purpura. N Engl J. Med. 1998; 339: 1585-1594; Furlan M, Lammle B. Deficiency of von Willebrand factor-cleaving se in familial and acquired thrombotic thrombocytopenic purpura. Baillieres Clin Haematol. 1998; 11:509-514). Genetic mutations in the ADAMTSl3 gene cause the familial form of TTP whereas people with acquired TTP do not have the mutations. , acquired TTP is terized by the production of specific antibodies.
In 1982, Moake et al. found unusually large von Willebrand factor (UL-vWF) multimers in the plasma of the patients with chronic relapsing TTP (Moake J L, Rudy C K, Troll J H, Weinstein M J, Colannino N M, Azocar J, Seder R H, Hong S L, Deykin D. Unusually large plasma factor VIII:von Willebrand factor multimers in chronic relapsing thrombotic thrombocytopenic purpura. N Engl J Med. 1982 ; 307: 435). The link between UL-vWF and TTP gained t with independent findings by Furlan et al. and Tsai and Lian that most patients suffering from TTP are deficient in a plasma metalloprotease, now known to be ADAMTSl3, that cleaves vWF (Furlan M, Robles R, Solenthaler M, Wassmer M, Sandoz P, e B. Deficient activity of von Willebrand factor-cleaving protease in chronic relapsing thrombotic thrombocytopenic purpura. Blood. 1997 ; 89:3097-3103; Tsai H M, Sussman, I I, Ginsburg D, Lankhof H, Sixma J J, Nagel R L.

Antibodies to von Willebrand factor-cleaving protease in acute otic thrombocytopenic purpura. N Engl J Med. 1998 ; 339:1585-1594).
The ADAMTS13 protease is a 190 kDa glycosylated n produced inantly by the liver (Levy G G, Nichols W C, Lian E C, Foroud T, McClintick J N, McGee B M, Yang A Y, Siemieniak D R, Stark K R, Gruppo R, Sarode R, Shurin S B, Chandrasekaran V, Stabler S P, Sabio H, Bouhassira E E, Upshaw J D, Jr., Ginsburg D, Tsai H M.

Partial amino acid sequence of purified von Willebrand factor-cleaving protease. Blood. 2001 ; 98: 1654-1661).
Mutations in the ADAMTS13 gene have been shown to cause TTP (Levy G G, Nichols W C, Lian E C, Foroud T, McClintick J N, McGee B M, Yang A Y, Siemieniak D R, Stark K R, Gruppo R, Sarode R, Shurin S B, Chandrasekaran V, Stabler S P, Sabio H, Bouhassira E E, Upshaw J D, Jr., Ginsburg D, Tsai H M. Mutations in a member of the ADAMTS gene family cause thrombotic thrombocytopenic purpura. . 2001 ; 413 :488- 494). Idiopathic TTP, often caused by autoantibodies inhibiting ADAMTS-13 activity, is a more common disorder that occurs in adults and older children and can recur at regular intervals in 11- 36% of patients (Tsai H M, Lian E C. Antibodies to von Willebrand factor-cleaving protease in acute thrombotic ocytopenic purpura. N Engl J Med. 1998 ; 339: 594; Furlan M, Lammle B. Deficiency ofvon Willebrand factor-cleaving protease in familial and ed thrombotic thrombocytopenic purpura. Baillieres Clin Haematol. 1998 ; 11:509-514).
Non neutralizing autoantibodies could also inhibit ADAMTS activity by inducing clearance from circulation (Scheiflinger F, Knobl P, Trattner B, Plaimauer B, Mohr G, Dockal M, Domer F, Rieger M. Nonneutralizing IgM and IgG antibodies to von Willebrand factor- cleaving se (ADAMTS-13) in a patient with otic thrombocytopenic purpura. Blood. 2003 ; 41-3243). Plasma ADAMTS13 activity in healthy adults ranges from 50% to 178% (Moake J L. otic thrombocytopenic purpura and the hemolytic uremic syndrome. Arch Pathol Lab Med. 2002 ; 126: 433). In most patients with familial or acquired TTP, plasma ADAMTS13 activity is absent or less than 5% of the normal. Without treatment the mortality rate exceeds 90%, but plasma therapy has reduced mortality to about 20% (Moake J L.
Thrombotic ocytopenic purpura and the hemolytic uremic syndrome. Arch Pathol Lab Med. 2002; 126:1430-1433). vWF synthesized in megakaryocytes and endothelial cells is stored in platelet-- granules and Weibel-Palade bodies, respectively, as ultra large vWF F) (Moake J L, Rudy C K, Troll J H, Weinstein M J, Colannino N M, Azocar J, Seder R H, Hong S L, Deykin D. Unusually large plasma factor VIII:von Willebrand factor multimers in chronic relapsing otic thrombocytopenic purpura. N Engl J Med. 1982 ; 307: 1432-1435; Wagner D D, Olmsted J B, Marder V J. Immunolocalization of von Willebrand protein in Weibel-Palade bodies of human endothelial cells. J Cell Biol. 1982; 95:355-360; Wagner D D, Bonfanti R. von Willebrand factor and the endothelium. Mayo Clin Proc. 1991 ; 66:621-627; Spom L A, Marder V J, Wagner D D. von Willebrand factor released from Weibel-Palade bodies binds more avidly to extracellular matrix than that secreted tutively. Blood. 1987 ; 69: 153 1-1534; Tsai H M, Nagel R L, Hatcher V B, Sussman, I I. Endothelial cell-derived high molecular weight von Willebrand factor is ted into the plasma multimer pattern by granulocyte proteases.
Biochem Biophys Res Commun. 1989 ; 158:980-985; Tsai H M, Nagel R L, Hatcher V B, Sussman, I I. Multimeric composition of endothelial erived von Willebrand factor. Blood. 1989 ; 73:2074-2076). Once secreted from endothelial cells, these UL-vWF ers are cleaved by ADAMTS13 in circulation into a series of smaller multimers at specific cleavage sites within the vWF molecule (Tsai H M, Nagel R L, Hatcher V B, Sussman, I I. Endothelial cell-derived high molecular weight von Willebrand factor is ted into the plasma multimer pattern by granulocyte ses. Biochem Biophys Res Commun. 1989 ; 158:980-985; Dent J A, Galbusera M, Ruggeri Z M. Heterogeneity of plasma von Willebrand factor multimers resulting from proteolysis of the constituent subunit. J Clin Invest. 1991 ; 88:774-782; Furlan M, Robles R, Affolter D, Meyer D, Baillod P, Lammle B. Triplet structure of von Willebrand factor reflects proteolytic degradation of high molecular weight multimers. Proc Natl Acad Sci USA. 1993 ; 90:7503-7507).
ADAMTS13 cleaves at the Tyr842-Met843 bond in the central A2 domain of the mature vWF subunit and requires zinc or calcium for activity (Dent J A, Berkowitz S D, Ware J, Kasper C K, Ruggeri Z M. Identification of a cleavage site directing the immunochemical detection of molecular abnormalities in type IIA von Willebrand factor. Proc Natl Acad Sci USA. 1990 ; 87:6306-6310). VWF exists in "ball-of—yam" and tous form as seen by electron microscopy (Slayter H, Loscalzo J, Bockenstedt P, Handin R 1. Native conformation of human von Willebrand protein. Analysis by electron microscopy and quasi-elastic light scattering. J Biol. Chem. 1985 ; 59-8563). rmore, atomic force microscopy s that VWF exits in a globular conformation under static ions and an unfolded filamentous state after exposure to shear stress (Siedlecki C A, Lestini B J, -Marchant K K, Eppell S J, Wilson D L, Marchant R E. Shear-dependent changes in the three-dimensional structure of human von rand . Blood. 1996 ; 9-2950). This could occur also in vivo when one end of the VWF filament is anchored to a surface.
Thrombi of TTP patients consist of little fibrin and mainly ofvWF and platelets, suggesting VWF-mediated et aggregation as a cause of thrombosis (Asada Y, Sumiyoshi A, i T, Suzumiya J, Kaketani K. Immunohistochemistry of vascular lesion in thrombotic thrombocytopenic purpura, with special nce to factor VIII related antigen. Thromb Res. 1985 ; 38:469-479). Patients with relapsing TTP have large multimers in the plasma. The UL-vWF ers accumulate over time because the persistence of the inhibitor (Anti- ADAMTS 13 Ab) decreases ADAMTS13 activity. The UL-vWF multimers are hyperactive and unfold as a result of shear stress causing platelet aggregation, resulting in intravascular thrombosis (Tsai H M. Von Willebrand factor, ADAMTS13, and thrombotic thrombocytopenic purpura. J Mol Med. 2002 ; 80:639-647; Tsai H M. Deficiency ofADAMTS-13 in thrombotic and thrombocytopenic purpura. J Thromb Haemost. 2003; 1:203 8-2040; discussion 2040-2035).
It is believed that the ce of hyper-reactive UL-vWF multimers in the plasma due to ADAMTSl3 deficiency could be associated with an increased risk of al thrombosis linked to coronary heart disease. Furthermore, ADAMTSl3 has been linked to cerebral infarction, myocardial tion, ischemic/reperfusion , deep vein thrombosis, and disseminated intravascular ation. Accordingly, there is a need for pharmaceutical formulations ofADAMTSl3 proteins suitable for the treatment of various diseases and conditions associated with ADAMTSl3 and VWF dysfilnction.
However, pharmaceutical formulations comprising very large and labile molecules such as ADAMTSl3 can generally only be administered intravenously. This is because such pharmaceutical formulations normally exhibit a very low ilablity due to insufficient absorption and severe degradation when given subcutaneously, intramuscularly, and intradermally. Accordingly, due to the low bioavailability, large and labile proteins are normally administered enously to provide direct availability to the blood stream.
] While ADAMTSl3 can be administered intravenously to treat various diseases and conditions associated with ADAMTSl3 and VWF dysfilnction, it is inconvenient and not easy for ts to handle. ularly, ADAMTSl3 formulations are often administered regularly throughout a patient’s life. For example, patients with familial (inherited) TTP begin treatment with intravenous ADAMTSl3 in their first year of life. Accordingly, it would be advantageous to subcutaneously administer a pharmaceutical composition ofADAMTSl3.
However, low bioavailabilities of subcutaneously administered large and labile n formulations has prevented the development of such subcutaneous formulations. us studies have reported that n coagulation factors VII, VIII, and IX that are suitable for subcutaneous administration. For example, PCT/SE95/00348 reports a Factor VIII formulation that is highly purified that contains additives such as hydrolyzed gelatin, hyaluronic acid, and soybean oil emulsion. The purification and additives allowed for the Factor VIII formulation to be highly concentrated. This highly concentrated ation ed in a bioavailability of at least about 15% and suitably at least about 30% after subcutaneous, intramuscular, or intradermal administration compared to the bioavailability after enous administration. However, 15-30% bioavailability of subcutaneous administration compared to intravenous administration is still very low and would not be effective at ng ADAMTSl3 disorders.
Furthermore, the prior studies do not provide a general principle for subcutaneous administration of large and labile proteins. Rather, prior studies present evidence of that it is subcuntaneous pharmaceutical compositions of large and labile proteins are difficult to prepare because the compositions lack the ite bioavailability for subcutaneous administration.
] Described herein is a method of subcutaneously administering an l3 formulation to a treat a disease or condition associated with ADAMTSl3 and VWF ction.
Specifically, evidence of the unexpectedly high ilability, up to approximately 70%, of ADAMTSl3 formulations administered subcutaneously is provided herein.

DETAILED DESCRIPTION OF THE INVENTION 1. INTRODUCTION ADAMTSl3 (A13) is a plasma metalloprotease which cleaves von Willebrand factor (VWF) ers and down regulates their activity in platelet aggregation. ADAMTSl3 is ated clotting disorders such as inherited thrombotic thrombocytopenic purpura (TTP), acquired TTP, cerebral infarction, myocardial infarction, ischemic/reperfusion injury, deep vein osis, and disseminated intravascular coagulation (DIC) such as sepsis-related DIC. 2014/026747 ] Current treatment of these clotting disorders involves intravenous stration ofADMTSl3 formulations. Treatment is currently limited to intravenous administration because ADAMTSl3 is a large protein and large proteins are generally not stable in formulations with high bioavailabilities suitable for subcutaneous administration. The mature l3 has a calculated molecular mass of about 145 kDa whereas purified plasma-derived ADAMTSl3 has an apparent molecular mass of about 180 kDa probably due to post-translational modifications consisting with t consensus sequences for 10 potential N-glycosylation sites, and several O-glycosylation sites and one C-mannosylation site in the TSPl repeats.
Proteins and molecules that are large and labile such as ADAMTSl3, are generally limited to intravenous administration due to the low ilability of the formulations when administered aneously. For example, previous s report that Factor VIII, a 170 to 300kDa protein, is typically administered intravenously because Factor VIII formulations normally exhibit a very low bioavailability due to insufficient absorption and severe degradation when administered subcutaneously, intramuscularly or intradermally. See PCT/SE95/00348.
For example, it has been reported that Factor VIII concentrate ed intramuscularly d a m circulating level of only 1.4% of the normal plasma level with and without sodium citrate as an additive to used to prevent degradation and increase absorption (Pool et al, New England J. Medicine, vol. 275, no. 10, p. 8, 1966). The studies further revealed that there was no significant difference in the activity recovered in the circulation regardless of whether such citrate was added to the preparation. In a later study, a high-purity factor VIII was administered uscularly to haemophilic dogs and human volunteers (Johnson et al, Br. J. Hematology, vol. 21, p. 21-41, 1971). Although, the doses were much larger than used by Pool et al., neither the dogs nor the human volunteers showed a significant rise in plasma factor VIII levels. In fact, the plasma factor VIII concentration in the haemophilic human eers remained below 1% of the normal plasma level, i.e. the severe haemophilia A prevailed even after administration in the absence of additives increasing the bioavailability.
There has been some success at subcutaneous delivery of small proteins such as Factor IX that do not degrade and aggregate like large, labile proteins such as Factor VIII and ADAMTSl3. For example, subcutaneous administration of factor IX without additives is known from ini et al., “Subcutaneous factor IX stration to patients with ilia B,” Am. J. Hematology, 47(1):6l-62, 1994. However, even Factor IX, which is only 56 kDa, exhibited poor and very slow transport into the circulation.
Due to the low ilability of proteins such as Factors VIII and IX as described above, methods of subcutaneous delivery of large and labile proteins are not generally pursued.
Rather, such proteins are normally given intravenously so that the formulation is directly available in the blood . It would however be advantageous if a medicament could be given subcutaneously because aneous administration is a minimally invasive mode of administration. Subcutaneous administration is also the most versatile mode of administration that can be used for short term and long term therapies. Subcutaneous administration can be performed by injection or by implantation of a sustained or timed release device beneath the surface of the skin. The site of the injection or device can be rotated when multiple injections or devices are needed.
Accordingly, subcutaneous formulations much easier to handle for the patient, especially since the formulation may have to be taken regularly during the whole life (e.g., starting as early as a child’s first year of life). Furthermore, the easy and speed of subcutaneous delivery allows increased t compliance and quicker access to medication when needed.
Thus, there is a benefit and need for subcutaneous formulations ofADAMTSl3.
The present invention is based on the unexpected discovery of a successful method of subcutaneously administering liquid and lyophilized formulations of purified ADAMTS proteins.
II. DEFINITIONS As used herein, "ADAMTSl3" or "A13" refer to a metalloprotease of the ADAMTS (a disintegrin and metalloproteinase with ospondin type I motifs) family that cleaves von Willebrand factor (vWF) n es Tyr 1605 and Met 1606. In the context of the present invention, an “ADAMTSl3 protein” es any ADAMTSl3 n, for example, ADAMTSl3 from a mammal such as a primate, human (NP6205 94), monkey, rabbit, pig, bovine (XP610784), rodent, mouse (NP001001322), rat (XP3423 96), hamster, gerbil, canine, feline, frog 083331), chicken (XP415435), and biologically active derivatives thereof. As used herein, “ADAMTS13 proteins” refer to recombinant and plasma derived ADAMTS13 proteins. Mutant and variant ADAMTS13 proteins having activity are also embraced, as are functional fragments and fusion proteins of the ADAMTS13 proteins.
Furthermore, the ADAMTS13 proteins of the ion may further comprise tags that facilitate purification, detection, or both. The 13 proteins described herein may further be modified with a therapeutic moiety or a moiety suitable imaging in vitro or in vivo.
Human ADAMTS13 proteins include, without limitation, polypeptides comprising the amino acid sequence of k accession number NP 620594 or a processed ptide thereof, for example a polypeptide in which the signal peptide (amino acids 1 to 29) and/or tide (amino acids 30-74) have been removed. Many l variants of human ADAMTS13 are known in the art, and are embraced by the formulations of the present invention, some of which include mutations selected from R7W, V88M, H96D, R102C, R193W, T1961, H234Q, A250V, R268P, W390C, R398H, Q448E, Q456H, P457L, P475S, C508Y, R528G, P6 1 8A, R625H, I673F, R692C, A732V, E740K, A900V, S903L, C908Y, C951G, G982R, C1024G, A1033T, R1095W, , R1 l23C, Cl2l3Y, Tl226l, G1239V, and R1336W. Additionally, ADAMTS13 ns include l and recombinant proteins that have been mutated, for example, by one or more conservative mutations at a non-essential amino acid.
Preferably, amino acids essential to the enzymatic activity ofADAMTS13 will not be mutated.
These include, for example, residues known or presumed to be essential for metal binding such as residues 83, 173, 224, 228, 234, 281, and 284, and es found in the active site of the enzyme, e.g., residue 225. Similarly, in the context of the present invention, ADAMTS13 proteins include alternate isoforms, for example, isoforms lacking amino acids 275 to 305 and/or 1 135 to 1 190 of the filll-length human protein.
Likewise, ADAMTS13 proteins may be r modified, for example, by post- translational cations (e. g., glycosylation at one or more amino acids ed from human residues 142, 146, 552, 579, 614, 667, 707, 828, 1235, 1354, or any other natural or engineered modification site) or by ex vivo chemical or enzymatic modification, including without limitation, ylation, modification by water soluble polymer (e. g., PEGylation, sialylation, tion, etc.), tagging, and the like.
As used herein, “blood clotting disorder” is defined as a disorder that includes dysfianctional platelet recruitment as well as dysfunctional neutrophil recruitment. Non-limiting es of “blood clotting disorders” include inherited thrombotic thrombocytopenic purpura (TTP), ed TTP, cerebral infarction, myocardial infarction, ischemic/reperfusion injury, deep vein thrombosis, and disseminated intravascular coagulation (DIC) such as sepsis-related DIC.
As used herein, "one unit TS13 ty" is d as the amount of activity in 1 ml of pooled normal human plasma, regardless of the assay being used. For example, one unit TSl3 FRETS-VWF73 activity is the amount of activity needed to cleave the same amount of FRETS-VWF73 substrate (Kokame et al., Br J Haematol. 2005 April ;129(l):93-100) as is cleaved by one ml of pooled normal human plasma. Additional activity assays can also be used to determine the activity of one unit ofADAMTS13. For example, direct ADAMTSl3 activity assays can be performed to detect the cleavage of either full-length VWF molecules or VWF fragments using SDS agrose gel ophoresis and indirect ion ofADAMTS13 activity can be detected with collagen binding assays.
As used , the terms "ADAMTS13" and "biologically active derivative", respectively, also e polypeptides obtained via recombinant DNA technology.
Alternatively, ADAMTS 13 can also refer to the plasma derived ADAMTS l3 purified from pooled human blood. The recombinant ADAMTSl3 ("rADAMTSl3"), e. g. recombinant human ADAMTSl3 ("r-hu-ADAMTSl3"), may be produced by any method known in the art. One c example is disclosed in WO 02/42441 which is incorporated herein by nce with respect to the method of producing recombinant ADAMTSl3. This may include any method known in the art for (i) the production of recombinant DNA by genetic engineering, e.g. via reverse transcription ofRNA and/or amplification of DNA, (ii) introducing recombinant DNA into prokaryotic or eukaryotic cells by transfection, i.e. via electroporation or microinj ection, (iii) cultivating said transformed cells, e.g. in a continuous or batchwise manner, (iv) expressing ADAMTSl3, e.g. constitutively or upon induction, and (v) isolating said ADAMTSl3, e.g. from the culture medium or by ting the ormed cells, in order to (vi) obtain substantially purified recombinant ADAMTSl3, e.g. via anion exchange chromatography or affinity chromatography. The term "biologically active tive" es also chimeric molecules such as, e.g. ADAMTSl3 (or a biologically active derivative thereof) in combination with Ig, in order to improve the biological/pharmacological properties such as, e. g. half life ofADAMTSl3 in the circulation system of a , particularly human. The Ig could have also the site of binding to an optionally mutated Fc receptor.
As used herein, the term "thrombus" refers to a blood clot, ally a platelet- comprising blood clot, a microthrombus, and/or an embolus. Said thrombus may be attached to an arterial or venous blood vessel or not, and may partially or completely block the blood flow in an arterial or venous blood vessel.
As used herein, a "therapeutically effective amount or dose" or "sufficient amount or dose" refers to a dose that es effects for which it is administered. The exact dose will depend on the purpose of the treatment, and will be ascertainable by one skilled in the art using known techniques (see, e. g., Lieberman, Pharmaceutical Dosage Forms (vols. 1-3, 1992); Lloyd, The Art, Science and Technology of Pharmaceutical Compounding (1999); Pickar, Dosage Calculations (1999); and Remington: The Science and Practice of Pharmacy, 20th n, 2003, Gennaro, Ed., Lippincott, Williams & Wilkins).
As used herein, a "physiological concentration" of salt refers to a salt concentration of between about 100 mM and about 200 mM of a ceutically acceptable salt. Non-limiting examples of pharmaceutically acceptable salts include, without limitation, sodium and potassium de, sodium and potassium e, sodium and potassium citrate, sodium and potassium phosphate.
As used herein, a "sub-physiological concentration" of salt refers to a salt concentration of less than about 100 mM of a pharmaceutically acceptable salt. In preferred embodiments, a sub-physiological tration of salt is less than about 80 mM of a pharmaceutical salt. In another preferred embodiment, a sub-physiological concentration of salt is less than about 60 mM of a pharmaceutical salt.
As used herein, the term "about" denotes an approximate range of plus or minus % from a specified value. For instance, the language "about 20%" encompasses a range of 18- 22%. As used herein, about also includes the exact amount. Hence "about 20%" means "about %" and also "20%." III.

The skilled person will readily be able to translate dosages between different mammals, for example from a mouse dose to a human dose.
One means for extrapolating a human dose from an animal dose includes the use of body surface area, which is known to correlate well with several metabolic parameters, e.g., blood volume, circulating plasma, and renal fianction, in diverse mammals. Thus, a conversion factor (e.g., Km) ating an e weight of a mammal to an average body surface area can be used to correlate a drug dosage (e.g., a dosage ofADAMTSl3), expressed in units of protein (e. g., mass or activity) per body weight of the mammal (e. g., kg), used for a first type ofmammal (e. g., a mouse) with a corresponding dose in a second type ofmammal (e.g., a human). For review, see Reagan-Shaw et al., FASEB, 22:659-62 (2007). For example, this can be done by first multiplying the drug dosage administered to the first type ofmammal by the conversion factor ined for that mammal, and then dividing the product by the conversion factor ined for the second type of mammal. Examples of such conversion factors are given below in Table 1, adopted from the US. Department of Health and Human Services guidelines for estimating the maximum safe starting dose in initial al trials for eutics in adult y volunteers .

In one embodiment, an ADAMTSl3 formulation is administered subcutaneously to reduce inflammation caused by the clotting disorder (e.g., an infarction), thereby preventing or reducing tissue damage (e.g., damage to the al damage) and/or to reduce reperfusion injury by ting leukocyte infiltration and damage. In one embodiment, an ADAMTSl3 formulation is administered subcutaneously to protect against secondary injury to infarct tissue (e.g., cerebral tissue and myocardial tissue) caused by reperfusion.
INHERITED TTP In one embodiment, an ADAMTS13 formulation described herein is used for the treatment and laxis of inherited TTP. Inherited TTP is due to genetic mutations of the ADAMTSl3 gene. ted TTP can lead to neurologic manifestations (e.g. mental status, stroke, es, hemiplegia, hesias, visual disturbance, and aphasia), fatigue, and severe ng. If left untreated, acquired TTP can be fatal or can cause lasting physiological damage.
Furthermore, because inherited TTP is due to a genetic mutation, life-long treatment is needed and patient compliance is required. While intravenous delivery ofADAMTSl3 formulations is effective at treating inherited TTP, intravenous delivery of drugs is not easy for patients to handle (especially en with ted TTP) and decreases patient compliance. Accordingly, it would be beneficial to develop a subcutaneous ADAMTS13 formulation and a method of ADAMTS13 subcutaneous delivery.

ACQUIRED TTP In c embodiments, an ADAMTSl3 formulation described herein is used for the treatment and prophylaxis of acquired TTP. In acquired TTP, patients have a low ADAMTSl3 activity due to the development of mune antibodies directed at ADAMTSl3.
Immune-complexed ADAMTSl3 is inactivated, neutralized and/or cleared from the blood stream and patient plasma. Reduced ADAMTSl3 activity leads to the accumulation of large uncleaved VWF multimers which can spontaneously adhere to platelets and leading to platelet- VWF-rich thrombi in the microcirculation. Like inherited TTP, acquired TTP can also lead to neurologic manifestations (e.g., mental status, stroke, seizures, hemiplegia, paresthesias, visual bance, and aphasia), e, and severe bleeding. If left untreated, acquired TTP can be fatal or can cause lasting logical damage. Accordingly, patient ance of l3 administration is ary to prevent permanent damage and eventual fatalities.
Thus, it would be beneficial to develop a subcutaneous ADAMTSl3 formulation and a method ofADAMTSl3 subcutaneous ry to increase patient ease and compliance as described above.

MYOCARDIAL INFARCT[ONAND REPERFUSIONINJURY In specific embodiments, an l3 formulation described herein is used for the treatment and prophylaxis of myocardial infarction. In specific embodiments, an ADAMTSl3 formulation described herein is used for the treatment and prophylaxis of ischemic/reperfusion injury. Reperfusion is the restoration of blood supply to tissue that is ischemic, due to decrease in blood supply. Reperfusion is a ure for treating infarction (e.g. , myocardial infarction and cerebral infarction) or other ischemia, by enabling viable ischemic tissue to recover, thus ng fiarther necrosis. However, reperfiJsion can itself fiarther damage the ischemic tissue, causing reperfusion injury. For example, acute myocardial infarction (AMI) is caused by thrombotic occlusion of a coronary artery. In addition to the immediate injury that occurs during deprivation of blood flow, ischemic/reperfusion injury involves tissue injury that occurs after blood flow is restored from the reperfusion.
Furthermore, it has been ed that ADAMTSl3 has an anti-inflammatory effect that prevents or ses secondary injury during ic reperfusion. De Meyer et al.
(“Protective anti-inflammatory effect ofADAMTSl3 on myocardial ia/reperfusion injury in mice,” Blood, 2012, 120(26):5217-5223). As described by De Meyer et al., VWF and ADAMTSl3 are involved in et adhesion and thrombus formation because ADAMTSl3 cleaves the most thrombogenic VWF multimers into smaller and less hemostatically active VWF fragments. De Meyer et al. also describe ADAMTS’s role in down-regulating inflammatory ses. It has also been shown that ADAMTS 13 can reduce thrombosis and inflammation (e.g., atherosclerosis). Chauhan et al. (“ADAMTSl3: a new link between thrombosis and inflammation,” J Exp Med., 2008, 205:2065-2074); Chauhan et a]. emic antithrombotic effects ofADAMTSl3,” J Exp Med., 2006, 203:767-776; Gandhi et al. (“ADAMTSl3 reduces ar inflammation and the development of early sclerosis in mice,” Blood, 2012, 119(10):2385-2391. 1] De Meyer et al. suggest that ADAMTSl3 ts excessive VWF-mediated platelet and leukocyte recruitment in the ischemic myocardium by cleaving VWF. Based on this hypothesis, De Meyer et al. show that neutrophil infiltration in the myocardium of animals with induced myocardial infarction was nine times lower when the animals were treated ADAMTSl3.
Accordingly, De Meyer et al. show that ADAMTSl3 reduces inflammatory responses in ischemic myocardium. This reduced inflammation also reduces reperfilsion injury by preventing leukocyte ation and damage. Thus, it would be beneficial to subcutaneously administer an ADAMTSl3 formulation to patients to avoid inflammation that results in tissue damage during infarction (e.g., myocardial infarction and cerebral infaction) and reperfiJsion because subcutaneous administration is easier and faster to administer than intravenous compositions that are generally administered by a medical sional.
In some embodiments, the pharmaceutical composition is administered immediately upon discovery of a dial tion, e.g., Within 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, 35 minutes, 40 minutes, 45 minutes, 50 minutes, 55 minutes, 60 minutes, 90 minutes, 110 s, 120 minutes, 3 hours, 4 hours, 5 hours, 6 hours, 7 hours, 8 hours, 9 hours, 10 hours, 11 hours, 12 hours, 13 hours, 14 hours, 15 hours, 16 hours, 17 hours, 18 hours, 19 hours, 20 hours, 21 hours, 22 hours, 23 hours, 24 hours, 25 or more hours, or any combination thereof, for ent of the tion and/or reperfilsion injury.
Accordingly, it is important to have a pharmaceutical composition that can be y and easily administered.

DEEP VEIN OSIS In one embodiment, an ADAMTSl3 formulation described herein is used for the treatment and/or prophylaxis of deep vein thrombosis (DVT). DVT is a blood clot that forms in a vein, deep in the body. While most deep vein clots occur in the lower leg or thigh, they can occur throughout the body. DVT is a particularly dangerous disease because a blood clot can break off and travel through the bloodstream (an embolus) to the heart, lungs, or brain, for example. Such embolisms can cause damage to organs and may result in death. Accordingly, as bed above, ADAMTSl3 ations can be used to treat DVT and resulting embolisms.
Furthermore, because DVT can develop and cause damage quickly, it is important to have a pharmaceutical composition that can be quickly and easily stered. Thus, it would be beneficial to develop a subcutaneous ADAMTSl3 formulation and a method ofADAMTSl3 subcutaneous delivery.

DISSEMINATED INTRA VASCULAR C0AGULATI0N In specific embodiments, an ADAMTSl3 formulation described herein is used for the treatment and prophylaxis of disseminated intravascular coagulation (DIC), specifically, sepsis-related DIC. DIC is a condition in which blood clots form throughout the body's small blood vessels. These blood clots can reduce or block blood flow throughout the body and can result in damage to tissues and organs. The blood clots in the small blood vessels results from an increase in clotting activity. This se in ty over uses available platelets and ng factors, y also increasing the chance of serious internal and external bleeding by depleting the available source of platelets and clotting factors. Accordingly, a patient with DIC will often suffer from blood clots and severe bleeding disorders.
Certain diseases such as sepsis, surgery/trauma, cancer, complications of irth/pregnancy, us snake bites (rattlesnakes and vipers), frostbite, and burns can cause ng factors to become overactive and can lead to DIC. DIC can also be acute (developing quickly over hours or days) or chronic (developing over weeks or months). While both types of DIC require medical treatment, acute DIC must be treated immediately to prevent excessive blood ng in the small blood vessels that quickly lead to severe bleeding.
Accordingly, it is important to have a pharmaceutical composition that can be quickly and easily administered to treat DIC, especially acute DIC such as sepsis-related DIC. Thus, it would be beneficial to p a subcutaneous ADAMTSl3 formulation and a method TSl3 aneous delivery.

VI. EXAMPLES e I .' The Pharmacokinetic Properties ofrADAMTSI3 with Intravenous and Subcutaneous Administration This study was ted to evaluate the pharmacokinetic properties of recombinant ADAMTS13 in Gottingen minipigs after intravenous (iv) or subcutaneous (s.c.) administration. In this study, 4 male Gottingen gs were administered i.v. ADMTS13 (the “intravenous ) and 4 male Gottingen minipigs were stered s.c. ADMTS13 (the taneous group”).
Male Gottingen minipigs were trained before the start of the study to cooperate with the study procedures. Thus, the animals were not restrained during administration of anesthetics or the test item and blood sampling.
The animals were anesthetized for catheter implantation using a l mix ting of 1.11 mg/kg tiletamine, 1.11 mg/kg zolazepam, 0.56 mg/kg xylazine, 0.56 mg/kg ketamine, and 0.11 mg/kg butorphanole (i.m.). Isoflurane was used for anesthesia maintenance when necessary. The animals received pure oxygen via a mask or an endotracheal tube during surgery. The jugular region was shaved and disinfected. A central catheter was inserted into the cranial V. cava using the Seldinger technique. 4 mg/kg carprofene was administered for analgesia before recovery from anesthesia.
The intravenous group ed a nominal dose of 200 FRETS-U/kg rADAMTS13 i.v. (0.085 mL/kg). The subcutaneous group ed a nominal dose of 1000 FRETS-U/kg rADAMTS 13 s.c. (0.456 mL/kg). Blood was sampled via the central venous catheter before administration of the test item and 5 min, 1 h, 3 h, 6 h, 9 h. 24 h, 32 h, 48 h, 56 h and 72 h after administration of the test item. Blood samples were prepared as follows: the first 0.5-0.7 mL were discarded to avoid dilution with the catheter lock solution (saline). Then, 0.8 mL blood was collected and mixed with 0.2 mL sodium citrate. The blood sample was centrifuged with 5700 rpm (1x 10 min, 1x 5 min). The plasma was stored at < -60 °C. 3] ADAMTS13 activity was determined by a FRETS assay and antigen by an ELISA. rmore, the potential development of binding dies against human rADAMTS13 and the influence ofrADAMTS13 on the er pattern of endogenous VWF were assessed.
As expected, after i.v. administration the median Tmax (time to Cmax) was 5min, indicating immediate bioavailability. Median Tmax after s.c. administration was 24h for ADAMTS13 activity and 28h for ADAMTS13 antigen. Mean plasma concentrations of ADAMTS13 activity are ized in Figure 1 and the averaged concentrations of ADAMTS13 antigen are summarized in Figure 2.
The dose-adjusted last[h*U/1’IIL/U/l{g and h"< ug/mL/ug/kg] after i.v. administration was 0.306 for activity and 0.373 for n. AUCO—tlast was computed using the trapezoidal rule from time point 0 to the last sampling time (tlast) (Hauschke et al. 2007). The dose-adjusted AUCO—tlast following s.c. administration was 0.198 for activity and 0.243 for antigen. Thus, the ratio of the dose-adjusted AUCO—tlast ing s.c. and iv. administration was 0.646 for activity and 0.651 for antigen. IVR [%] was 55.8 (activity) and 79.3 (antigen) after i.v. administration and 13.8 (activity) and 17.3 (antigen) after s.c. administration.
Since the plasma level of rADAMTS13 did not decline sufficiently during the ation period, the estimation of the terminal and initial ives has to be viewed with caution. Thus, the dependent parameters (MRT, Vss, Cls, AUCO—inf) may be unreliable as well. A follow-up study will be conducted to assess these parameters. Assessment of binding antibodies against rADAMTS13 was negative for all samples from all animals. s of the assessment of the gs’ VWF er pattern were indicative for a very limited cleavage of endogenous VWF by recombinant ADAMTS13 (Table 3). The satellite band close to a low VWF-mer slightly increased in intensity over time in s receiving s.c. administration, but not in animals receiving i.v. administration. The height of the VWF multimer patterns did not change in either group.

In this study, 4 male Gottingen minipigs were administered i.v. ADMTS13 (the “intravenous group”) and 4 male Gottingen minipigs were administered s.c. ADMTS13 (the “subcutaneous group”).
The male Gottingen gs were acclimated to study procedures and anesthetized for catheter tation as described in e 1.
This study was a trial using 3 and 5 male Gottingen minipigs per group. Both groups received a l dose of 200 FRETS-U/kg rADAMTS13. Three animals were dosed iv, the other five animals were dosed s.c.. Blood was sampled via the central venous catheter before administration of the test item and 5min, 1h, 2h, 6h, 5h, 23h, 30h, 47h, 54h, 71h, 78h, 95h and 102h after administration of the test item.
Blood samples were prepared as follows: The first 0.5-0.7 mL were discarded to avoid dilution with the er lock solution (saline). Then, 0.8 mL blood was collected and mixed with 0.2 mL sodium e. The blood sample was centrifuged with 5700 rpm (1x 10min, 1x 5min). The plasma was stored at < -60°C.
ADAMTS13 activity was determined by a FRETS assay and antigen by an ELISA.
As expected, after i.v. administration the median Tmax (time to Cmax) was 5min, indicating immediate ilability. Median Tmax after so. administration was 30h. Mean plasma concentrations ofADAMTS13 activity are summarized in Figure 3 and the averaged concentrations ofADAMTS13 antigen are summarized in Figure 4.
