Method of treating amyotrophic lateral sclerosis with pridopidine
Provided herein is a method for treating a human subject afflicted with ALS by administering to the subject a therapeutically effective amount of pridopidine as monotherapy or together with riluzole, edaravone, combination of dextromethorphan/quinidine, sodium phenylbutyrate (PB), tauroursodeoxycholic acid or combination of sodium phenylbutyrate (PB)/tauroursodeoxycholic acid (i.e. AMX0035) as combination or add-on therapy.
1. A method for treating a subject afflicted with sporadic amyotrophic lateral sclerosis (ALS), comprising periodically administering to the subject an amount of pridopidine or a pharmaceutically acceptable salt thereof effective to treat the subject.
2. The method of claim 1 , wherein the amount of pridopidine is effective to inhibit or reduce progression of a symptom of the sporadic ALS in the subject.
3. The method of claim 2 , where in the symptom is muscles stiffness, muscle weakness, muscle wasting, muscle cramps, difficulty speaking, difficulty swallowing, difficulty breathing, difficulty chewing, difficulty walking, fasciculations, and/or worsening posture.
4. The method of claim 1 , wherein the amount of pridopidine is effective to enhance BDNF axonal transport in motor neurons, enhance ERK activation in motor neurons, improve NMJ formation and preservation, preserve NMJ structure, preserve NMJ function, improve innervation rate of muscle tissue, enhance motor neuron axonal growth, reduce axonal degeneration, reduce motor neuron axonal degeneration, enhance muscle cell survival, enhance muscle fiber diameter and function, reduce SOD1 aggregation, lessen pseudobulbar disease progression, reduce progression of muscle fiber wasting, and/or improve muscle contraction in the subject afflicted with ALS.
5. The method of claim 1 , wherein the amount of pridopidine is administered daily, twice a week, three times a week or more often than once daily.
6. The method of claim 1 , wherein the amount of pridopidine is administered twice daily.
7. The method of claim 1 , wherein the amount of pridopidine is administered orally.
8. The method of claim 1 , wherein the amount of pridopidine administered is 10 mg per day to 90 mg per day.
9. The method of claim 1 , wherein the pridopidine is pridopidine hydrochloride.
10. The method of claim 1 , wherein the subject is a human subject.
11. The method of claim 1 , further comprising administering to the subject a therapeutically effective amount of a second compound, wherein the second compound is riluzole, edaravone, dextromethorphan/quinidine, sodium phenylbutyrate (PB), tauroursodeoxycholic acid or sodium phenylbutyrate (PB)/tauroursodeoxycholic acid.
12. The method of claim 11 , wherein the administration of the second compound precedes the administration of pridopidine.
13. The method of claim 11 , wherein the administration of pridopidine precedes the administration of the second compound.
14. The method of claim 11 , wherein the pridopidine is administered adjunctively to the second compound.
15. The method of claim 11 , wherein the second compound is administered adjunctively to the pridopidine.
