Treatment for wolfram syndrome and other endoplasmic reticulum stress disorders
The present invention generally relates to a method of treating or preventing an endoplasmic reticulum stress disorder in subjects, such as a method of treating or preventing Wolfram syndrome.
1. A method of treating Wolfram Syndrome in a subject in need thereof comprising administering to the subject a therapeutically effective amount of a ryanodine receptor inhibitor, wherein the ryanodine receptor inhibitor comprises azumolene or a pharmaceutically acceptable salt or hydrate thereof.
2. The method of claim 1 , wherein the ryanodine receptor inhibitor is administered intravenously in an amount of from about 0.05 mg to about 30 mg per kg of body weight.
3. The method of claim 1 , wherein the ryanodine receptor inhibitor is administered orally in an amount of from about 0.1 mg to about 75 mg per kg of bodyweight.
4. The method of claim 1 , wherein the ryanodine receptor inhibitor is administered in a composition further comprising a pharmaceutically acceptable carrier.
5. The method of claim 4 , wherein the composition further comprises at least one second active agent, wherein the second active agent modulates the transport of calcium (Ca2+) ions to and/or from the endoplasmic reticulum in a cell.
6. The method of claim 1 , wherein the subject is a human.
7. A method of treating Wolfram Syndrome in a human subject in need thereof comprising administering to the subject a therapeutically effective amount of a composition comprising dantrolene or a pharmaceutically acceptable salt or hydrate thereof, wherein the human subject has an age that is 16 years or less.
8. The method of claim 7 , wherein the composition comprises dantrolene sodium.
9. The method of claim 7 , wherein the composition further comprises a pharmaceutically acceptable carrier.
10. The method of claim 8 , wherein the dantrolene sodium is administered intravenously in an amount of from about 0.05 mg to about 30 mg per kg of body weight.
11. The method of claim 8 , wherein the dantrolene sodium is administered orally in an amount of from about 0.1 mg to about 75 mg per kg of bodyweight.
12. The method of claim 7 , further comprising administering at least one second active agent.
13. The method of claim 12 , wherein the second active agent modulates the transport of calcium (Ca2+) ions to and/or from the endoplasmic reticulum in a cell.
14. The method of claim 12 , wherein the second active agent comprises a compound that enhances the activity of sarco/endoplasmic reticulum calcium adenosine triphosphatase (SERCA) pumps.
15. The method of claim 14 , wherein the second active agent comprises pioglitazone.
16. A method of treating Wolfram Syndrome in a human subject in need thereof consisting of administering to the subject a therapeutically effective amount of a composition consisting of dantrolene or a pharmaceutically acceptable salt or hydrate thereof and one or more pharmaceutically acceptable carriers.
17. The method of claim 16 , wherein the dantrolene or a pharmaceutically acceptable salt or hydrate thereof comprises dantrolene sodium.
18. A method of treating Wolfram Syndrome in a human subject in need thereof comprising administering to the subject a therapeutically effective amount of a composition comprising dantrolene or a pharmaceutically acceptable salt or hydrate thereof, wherein the subject does not have Type 1 or Type 2 diabetes.
19. The method of claim 18 , wherein the composition comprises dantrolene sodium.
20. The method of claim 19 , wherein the dantrolene sodium is administered intravenously in an amount of from about 0.05 mg to about 30 mg per kg of body weight or orally in an amount of from about 0.1 mg to about 75 mg per kg of bodyweight.
