Combination therapies using cyclosporine and aromatic cationic peptides
The invention provides compositions and methods for preventing or treating an ischemia-reperfusion injury, such as occurs during acute myocardial infarction and organ transplant in a mammalian subject. The methods comprise administering to the subject an effective amount of an aromatic-cationic peptide or a pharmaceutically acceptable salt thereof, and one or more additional active agents such as cyclosporine.
1. A method for treating ischemia and/or reperfusion injury in a subject in need thereof, the method comprising administering an effective amount of (i) an aromatic-cationic peptide or a pharmaceutically acceptable salt thereof, wherein the aromatic-cationic peptide is selected from the group consisting of: Tyr-D-Arg-Phe-Lys-NH 2 ; 2′,6′-Dmt-D-Arg-Phe-Lys-NH 2 ; Phe-D-Arg-Phe-Lys-NH 2 ; 2′,6′-Dmp-D-Arg-Phe-Lys-NH 2 ; and D-Arg-2′,6′-Dmt-Lys-Phe-NH 2 and (ii) an additional active agent consisting of cyclosporine; wherein the aromatic-cationic peptide is linked to cyclosporine by a linker.
2. The method of claim 1 , wherein the pharmaceutically acceptable salt comprises acetate salt or trifluororacetate salt.
3. The method of claim 1 , wherein the additional active agent comprises cyclosporine A.
4. The method of claim 1 , wherein the aromatic-cationic peptide comprises D-Arg-2′6′-Dmt-Lys-Phe-NH 2 or a pharmaceutically acceptable salt thereof selected from acetate salt or trifluororacetate salt, and wherein the additional active agent is cyclosporine A.
5. A composition comprising: an (i) an aromatic-cationic peptide or a pharmaceutically acceptable salt thereof, wherein the aromatic-cationic peptide is selected from the group consisting of: Tyr-D-Arg-Phe-Lys-NH 2 ; 2′,6′-Dmt-D-Arg-Phe-Lys-NH 2 ; Phe-D-Arg-Phe-Lys-NH 2 ; 2′,6′-Dmp-D-Arg-Phe-Lys-NH 2 ; and D-Arg-2′,6′-Dmt-Lys-Phe-NH 2 , and (ii) an additional active agent consisting of cyclosporine; wherein the aromatic-cationic peptide is linked to cyclosporine by a linker.
6. The composition of claim 5 , wherein the pharmaceutically acceptable salt comprises acetate salt or trifluororacetate salt.
7. The composition of claim 5 , wherein the additional active agent comprises cyclosporine A.
8. The composition of claim 5 , wherein the aromatic-cationic peptide comprises D-Arg-2′,6′-Dmt-Lys-Phe-NH 2 or a pharmaceutically acceptable salt thereof selected from acetate salt or trifluororacetate salt; wherein the additional active agent is cyclosporine A; and wherein the linker comprises an enzyme-cleavable linker.
9. The method of claim 1 , wherein the aromatic-cationic peptide is administered intravenously, intradermally, intraperitoneally, subcutaneously, orally, transdermally, topically, intraocularly, iontophoretically, transmucosally, or by inhalation.
10. The method of claim 1 , wherein the ischemia and/or reperfusion injury comprises vessel occlusion injury or cardiac ischemia-reperfusion injury.
11. The composition of claim 5 , wherein the aromatic-cationic peptide is administered intravenously, intradermally, intraperitoneally, subcutaneously, orally, transdermally, topically, intraocularly, iontophoretically, transmucosally, or by inhalation.
12. The composition of claim 5 , wherein the aromatic-cationic peptide comprises D-Arg-2′,6′-Dmt-Lys-Phe-NH2 or a pharmaceutically acceptable salt thereof selected from acetate salt or trifluororacetate salt; wherein the additional active agent is cyclosporine A; and wherein the linker comprises a pH-sensitive linker.
13. The method of claim 4 , wherein the linker is selected from the group consisting of an enzyme-cleavable linker and a pH-sensitive linker.
