PRIDOPIDINE AND ANALOGS THEREOF FOR THE TREATMENT OF NEURODEGENERATIVE EYE DISEASE
This application provides a composition comprising pridopidine or pharmaceutically acceptable salt thereof and at least one of compounds 1-8 (described herein) or pharmaceutically acceptable salt thereof for use in the treatment of neurodegenerative eye disease, symptoms thereof, and additional neurodegenerative disorders.
1 . A method of treating, reducing or inhibiting a neurodegenerative eye disease or a symptom thereof in a subject comprising administering to the subject a composition comprising pridopidine or pharmaceutically acceptable salt thereof and at least one of compounds 1-8 or pharmaceutically acceptable salt thereof; wherein compounds 1-8 are represented by the following structures:
2 . The method of claim 1 , wherein the composition comprises pridopidine or pharmaceutically acceptable salt thereof and Compound 1 or pharmaceutically acceptable salt thereof.
3 . The method of claim 1 , wherein the composition comprises pridopidine or pharmaceutically acceptable salt thereof and Compound 4 or pharmaceutically acceptable salt thereof.
4 . The method of claim 1 , wherein the composition comprises pridopidine or pharmaceutically acceptable salt thereof and Compound 1 and Compound 4 or pharmaceutically acceptable salt thereof.
5 . The method of claim 1 , wherein the neurodegenerative eye disease is selected from the group consisting of glaucoma, Age-related Macular Degeneration (AMD), geographic atrophy (GA), optic neuropathy, Microphthalmia, syndromic 12 (MCOPS12) and retinitis pigmentosa.
6 . The method of claim 5 , wherein the Age-related Macular Degeneration is Wet Age-related Macular Degeneration (“Wet AMD”) or Dry Age-related Macular Degeneration (“Dry AMD”).
7 . The method of claim 5 , wherein the optic neuropathy is Leber hereditary optic neuropathy.
8 . The method of claim 5 , wherein the glaucoma is open-angle glaucoma, primary open-angle-glaucoma, angle-closure glaucoma, pigmentary glaucoma, pseudoexfoliative glaucoma, neovascular glaucoma, steroid-induced glaucoma, normal-tension glaucoma, pressure-independent glaucoma or any combination thereof.
9 . The method of claim 1 , wherein the symptom is retinal ganglion cell damage, retinal ganglion cell loss, an optic nerve axon loss or damage, macular degeneration, a retinal ganglion cell (RGC) loss or damage, a retinal pigment epithelium cell (RPE) loss or death or any combination thereof.
10 . The method of claim 1 , wherein the composition is effective in
reducing or preventing retinal ganglion cell (RGC) loss or damage in the subject,
improving retinal ganglion cell (RGC) viability in the subject,
reducing or preventing optic nerve axon loss or damage in the subject,
reducing or preventing optic nerve head astrocytes (ONHAs) loss or damage in the subject,
reducing oxidative stress in ONHAs,
improving optic nerve head astrocytes (ONHAs) viability in the subject,
increasing cell viability in the subject,
reducing or preventing retinal pigment epithelium cell (RPE) loss or death in a subject,
protecting an optic nerve axon from degeneration in the subject,
or any combination thereof.
11 . The method of claim 10 , wherein the axon degeneration is induced by elevated intraocular pressure.
12 . The method of claim 10 , wherein the cell viability is increased by at least 3%, by at least 5%, by at least 10%, by at least 20%, or by at least 25%.
13 . The method of claim 10 , wherein the optic nerve axon loss is reduced by at least 3%, by at least 5%, by at least 10%, by at least 20%, by at least 30%, by at least 40% or by at least 50%.
14 . The method of claim 13 , wherein the optic nerve axon loss is reduced by more than 50%, more than 60%, more than 70%, or more than 80%.
15 . The method of claim 10 , wherein the retinal ganglion cell loss is reduced by at least 10%, by at least 20%, by at least 30%, by at least 40% or by at least 50%.
16 . The method of claim 15 , wherein the retinal ganglion cell loss is reduced by more than 50%, more than 60%, more than 70%, or more than 80%.
17 . The method of claim 10 , wherein the optic nerve head astrocyte (ONHA) loss is reduced by at least 10%, by at least 20%, by at least 25%, by at least 30%, by at least 35%, by at least 40% or by at least 50%.
18 . The method of claim 1 , wherein the composition comprises a unit dose of between 22.5 mg to 315 mg.
19 . The method of claim 18 , wherein the composition is administered once a day, twice a day or three times a day.
20 . The method of claim 1 , wherein the composition is administered orally or topically.
21 . The method of claim 1 , wherein the composition is administered intraocularly, intravitreally, periocularly or ocularly.
22 . The method of claim 21 , wherein the composition is administered by an eye drop application to the conjunctiva.
