Treatment of subarachnoid hemorrhage with ApoE analogs
Novel ApoE peptide derivatives and ApoE-protein transduction domain conjugates are disclosed which are useful for treating disorders including subarachnoid hemorrhage, intracerebral hemorrhage, and intraventricular hemorrhage and other brain disorders. The invention encompasses methods for treating cerebral vasospasm by administration of at least one ApoE or ApoE mimetic peptide.
1. A method of treating or ameliorating a cerebral hemorrhage comprising administering to a subject in need thereof a peptide compound, said peptide compound comprising a peptide consisting of less than about 50 amino acids comprising the sequence of peptide COG133 (SEQ ID NO: 1), wherein said peptide is conjugated to a PTD derived from antennapedia.
2. The method of claim 1 , wherein said cerebral hemorrhage is selected from the group consisting of intraventricular hemorrhage (IVH), intracerebral hemorrhage (ICH), and subarachnoid hemorrhage (SAH).
3. The method of claim 2 , wherein said subarachnoid hemorrhage is aneurismal subarachnoid hemorrhage.
4. The method of claim 1 , wherein said peptide compound is administered within about 24-72 hours after subarachnoid hemorrhage has occurred.
5. The method of claim 1 , wherein said peptide compound is administered within the first several weeks after subarachnoid hemorrhage has occurred.
6. The method of claim 1 , wherein said peptide compound is administered at least about every 8 hours.
7. The method of claim 1 , wherein said peptide compound is administered at least about every 12 hours.
8. The method of claim 1 , wherein said peptide compound is administered during surgery to treat subarachnoid hemorrhage.
9. The method of claim 1 , further comprising co-administering a therapeutic amount of at least one additional active agent.
10. The method of claim 9 , wherein said additional active agent is a voltage-gated calcium channel inhibitor.
11. The method of claim 10 , wherein said voltage-gated calcium channel inhibitor is a small molecule.
12. The method of claim 11 , wherein said small molecule is nimodipine.
13. The method of claim 1 , wherein said subject has suffered a cerebral vasospasm.
14. The method of claim 1 , wherein said subject is at risk of a cerebral vasospasm.
15. The method of claim 1 , wherein said peptide compound is a pharmaceutically acceptable salt, solvate, and/or amide.
16. The method of claim 1 , wherein said peptide compound is administered orally and/or intravenously.
17. The method of claim 1 , wherein one to fifteen amino acids are linked to the amino or carboxy terminus of said COG133 peptide.
18. The method of claim 1 , wherein an amino acid has been inserted at the amino or carboxy terminus of said COG133 peptide.
19. The method of claim 1 , wherein said PTD derived from antennapedia is RQIKIWFQNRRMKWKK (SEQ. ID. NO: 51) or RRMKWKK (SEQ. ID. NO: 52).
20. The method of claim 1 , wherein said peptide compound consists of the sequence of peptide COG133 (SEQ ID NO: 1).
