COMPOSITIONS AND METHODS FOR THE TREATMENT OF AMYOTROPHIC LATERAL SCLEROSIS, PARKINSON’S DISEASE, PARKINSON’S DISEASE WITH DEMENTIA, DEMENTIA WITH LEWY BODIES, AND MULTIPLE SYSTEM ATROPHY
The present disclosure provides novel methods for treating or preventing amyotrophic lateral sclerosis (ALS), methods for delaying the onset of neurological symptoms associated with ALS, increasing survival in subjects afflicted with ALS, and attenuating the decline of muscle strength associated with ALS in a subject in need thereof. The present disclosure also provides methods for treating or preventing α-synucleinopathy or TDP-43 proteinopathy. The methods comprise administering to the subject an effective amount of a mitochondria-targeting peptidomimetic compound, such as (R)-2-amino-N-((S)-1-(((S)-5-amino-1-(3-benzyl-1,2,4-oxadiazol-5-yl)pentyl)amino)-3-(4-hydroxy-2,6-dimethylphenyl)-1-oxopropan-2-yl)-5-guanidinopentanamide, or a pharmaceutically acceptable salt, stereoisomer, tautomer, hydrate, and/or solvate thereof.
1 .- 105 . (canceled)
106 . A method for treating amyotrophic lateral sclerosis (ALS) in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of the peptidomimetic (R)-2-amino-N-((S)-1-(((S)-5-amino-1-(3-benzyl-1,2,4-oxadiazol-5-yl)pentyl)amino)-3-(4-hydroxy-2,6-dimethylphenyl)-1-oxopropan-2-yl)-5-guanidinopentanamide, or a pharmaceutically acceptable salt, stereoisomer, tautomer, hydrate, and/or solvate thereof, and riluzole (Rilutek®).
107 . The method of claim 106 , wherein the subject has been diagnosed as having ALS.
108 . The method of claim 106 , wherein the ALS is familial.
109 . The method of claim 108 , wherein the familial ALS is caused by a mutation in the superoxide dismutase 1 (SOD1) gene or TARDBP (TAR DNA binding protein) gene.
110 . The method of claim 106 , wherein the treating comprises reducing plasma accumulation of neurofilament light chain (NfL).
111 . The method of claim 106 , wherein the subject is a mammal.
112 . The method of claim 111 , wherein the mammalian subject is a human.
113 . The method of claim 106 , wherein the peptidomimetic is administered orally or subcutaneously.
114 . The method of claim 106 , wherein the peptidomimetic is administered topically, intranasally, systemically, intravenously, intraperitoneally, intradermally, intraocularly, ophthalmically, intrathecally, intracerebroventricularly, iontophoretically, transmucosally, intravitreally, or intramuscularly.
115 . The method of claim 106 , wherein the peptidomimetic is formulated as a tris-HCl salt, a bis-HCl salt, or a mono-HCl salt.
116 . A method for treating amyotrophic lateral sclerosis (ALS) in a subject in need thereof, comprising administering to the subject a therapeutically effective amount of the peptidomimetic (R)-2-amino-N-((S)-1-(((S)-5-amino-1-(3-benzyl-1,2,4-oxadiazol-5-yl)pentyl)amino)-3-(4-hydroxy-2,6-dimethylphenyl)-1-oxopropan-2-yl)-5-guanidinopentanamide, or a pharmaceutically acceptable salt, stereoisomer, tautomer, hydrate, and/or solvate thereof, and edaravone (Radicava®).
117 . The method of claim 116 , wherein the subject has been diagnosed as having ALS.
118 . The method of claim 116 , wherein the ALS is familial.
119 . The method of claim 118 , wherein the familial ALS is caused by a mutation in the superoxide dismutase 1 (SOD1) gene or TARDBP (TAR DNA binding protein) gene.
120 . The method of claim 116 , wherein the treating comprises reducing plasma accumulation of neurofilament light chain (NfL).
121 . The method of claim 116 , wherein the subject is a mammal.
122 . The method of claim 121 , wherein the mammalian subject is a human.
123 . The method of claim 116 , wherein the peptidomimetic is administered orally or subcutaneously.
124 . The method of claim 116 , wherein the peptidomimetic is administered topically, intranasally, systemically, intravenously, intraperitoneally, intradermally, intraocularly, ophthalmically, intrathecally, intracerebroventricularly, iontophoretically, transmucosally, intravitreally, or intramuscularly.
125 . The method of claim 116 , wherein the peptidomimetic is formulated as a tris-HCl salt, a bis-HCl salt, or a mono-HCl salt.
