COMPOSITIONS COMPRISING ADAMTS13 FOR USE IN METHODS FOR THE RECANALIZATION OF OCCLUDED BLOOD VESSELS IN AN INFARCTION
Provided herein are methods for recanalization of occluded blood vessels in a subject having an infarction. The method includes a step of administering to the subject a therapeutically effective amount of isolated ADAMTS13 protein at particular dosages and ranges of times after detection of the infarction. As described herein, ADAMTS13 advantageously recanalizes occluded blood vessels and reduces infarction size, even when administered a prolonged period after stable occlusion. Accordingly, such methods and compositions are useful for the treatment of infractions caused by blood vessel occlusion.
1 . A method for recanalization of an occluded blood vessel in a subject having a cerebral infarction, comprising the step of administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of isolated ADAMTS13 protein, thereby recanalizing the occluded blood vessel.
2 . The method of claim 1 , wherein the pharmaceutical composition is administered to the subject at a dose of about 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1,000, 1,250, 1,500, 1,750, or 2,000 U/kg and/or
wherein the pharmaceutical composition is administered to the subject within 15, 30, 60, 90, 120, 180, 210, 240, 270 or 300 minutes of detection of the infarction.
3 . A method for treating a cerebral infarction in a subject by recanalization of an occluded blood vessel in the subject, the method comprising the step of administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of isolated ADAMTS13 protein, thereby treating the cerebral infarction.
4 . The method of claim 3 , wherein the pharmaceutical composition is administered to the subject at a dose of about 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1,000, 1,250, 1,500, 1,750, or 2,000 U/kg and/or
wherein the pharmaceutical composition is administered to the subject within 15, 30, 60, 90, 120, 180, 210, 240, 270 or 300 minutes detection of the infarction.
5 . The method of claim 1 , wherein the pharmaceutical composition is administered to the subject at a dose of about 40, 50, 60, 70, 80, 90, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, 650, 700, 750, 800, 850, 900, 950, 1,000, 1,250, 1,500, 1,750, or 2,000 U/kg; and
wherein the pharmaceutical composition is administered to the subject within 15, 30, 60, 90, 120, 180, 210, 240, 270 or 300 minutes of detection of the infarction.
6 . A method for recanalization of an occluded blood vessel in a subject having a cerebral infarction, comprising the step of administering to the subject a pharmaceutical composition comprising a therapeutically effective amount of isolated ADAMTS13 protein, thereby recanalizing the occluded blood vessel,
wherein the pharmaceutical composition is administered to the subject at an amount that increases the level of the ADAMTS13 protein in the subject 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, or 20-fold greater than the level of ADAMTS13 protein in the subject prior to the administering.
7 . The method of claim 6 , wherein the pharmaceutical composition administered to the subject within 15, 30, 60, 90, 120, 180, 210, 240, 270 or 300 minutes of detection of the infarction.
8 . The method of claim 1 , wherein the regional cerebral blood flow in the subject is improved by at least 25% as compared to a control subject not having a cerebral infarction.
9 . The method of claim 1 , wherein the regional cerebral blood flow is improved by at least 50% as compared to the regional cerebral blood flow in the control subject.
10 . The method of claim 1 , wherein the regional cerebral blood flow is improved by at least 75% as compared to the regional cerebral blood flow in the control subject.
11 . The method of claim 1 , wherein the isolated ADAMTS13 protein is glycosylated.
12 . The method of claim 1 , wherein the isolated ADAMTS13 protein has a plasma half-life of more than 1 hour.
13 . The method of claim 1 , wherein the isolated ADAMTS13 protein is recombinantly produced by HEK293 cells.
14 . The method of claim 1 , wherein the isolated ADAMTS13 protein is recombinantly produced by CHO cells.
15 . The method of claim 1 , wherein the pharmaceutical composition is administered multiple times or by continuous infusion.
16 . The method of claim 1 , wherein said administration does not increase the level of hemorrhage, as compared to the level of hemorrhage in a subject not receiving the pharmaceutical composition.
17 . The method of claim 1 , wherein said administration reduces infarct volume.
18 . The method of claim 17 , wherein the infract volume is reduced by at least 50% compared to the infract volume in a control subject not having a cerebral infarction.
