Definitions
- the present invention relates to a pharmaceutical composition for the treatment or inhibition of progression of levodopa-induced dyskinesia, and a method of treating or inhibiting the progression of levodopa-induced dyskinesia with the pharmaceutical composition.
- Parkinson's disease is a neurological disorder caused by degeneration of the dopaminergic neuron of the striatum-black matter of the cerebral basal ganglia. It is a disease (Fahn, 2003).
- the drug therapy for Parkinson's disease is primarily a dopamine agonist or dopamine precursor L-3,4-dihydroxyphenylalanine (L-DOPA) therapy is mainly selected and implemented (Olanow et al., 2001).
- L-DOPA L-3,4-dihydroxyphenylalanine
- long-term L-DOPA therapy in Parkinson's disease animal models causes neurotoxicity due to the formation of reactive oxygen species (ROS) and changes in downstream gene/protein expression, and long-term administration of L-DOPA in Parkinson's disease patients. Not only decreases drug efficacy, but also causes dyskinesia, motor fluctuation and other complications (Jankovic, 2005).
- ROS reactive oxygen species
- Dyskinesia is a side effect of abnormal movement caused by confusion caused by reflux waves in motor muscles.40% of patients who have started L-DOPA treatment for 4-5 years, 9-15 years old Symptoms have been reported in 90% of patients (Nutt, 1990; Quinn, 1995). This dyskinesia is called peak-dose dyskinesia because it responds when the concentration of L-DOPA in the brain is highest (Olanow et al., 2004).
- LID Levodopa-Induced Dyskinesia
- levodopa-induced dyskinesia is related to the expression of genes and proteins in the striatum in which the dopamine nerve is destroyed.
- ⁇ FosB protein expression and extracellular signal-regulated kinase 1/2, ERK1/2 phosphorylation has been reported to be highly related (Andersson et al., 2001; Pav ⁇ n N. et al., 2006).
- ERK1/2 phosphorylation by L-DOPA was related to the expression of AIMs (Abnormal involuntary movements, AIMs), which indicates the degree of dyskinesia. (Westin et al., 2007).
- GLP-1 has been shown to be related to cognition and behavior (During et al., 2003).
- a number of studies have suggested GLP-1 receptor agonists as new treatments for degenerative brain diseases including Parkinson's disease, Alzheimer's disease, Huntington's disease, traumatic brain injury, stroke and peripheral neurosis.
- GLB blood-cerebral barrier
- GLP-1 has a short half-life of 1-2 minutes and is a GLP-1-transferrin fusion created to increase the half-life of GLP-1 by approximately 2 days by conferring resistance to the inactivation of GLP-1.
- Protein (GLP-1-Tf) cannot cross the BBB (Kim et al., 2010; Martin et al., 2012).
- Exendin-4 has been shown to improve rotarod performance compared to GLP-1-Tf (Martin et al., 2012), and although its entry speed is limited, it is known to enter the brain from blood (Kastin AJ et al. , 2003). In addition, exendin-4 was not shown to be effective in providing neuroprotection in an MPTP mouse model for Parkinson's disease, even when given daily for 7 days after treatment (Liu et al., 2015).
- An object of the present invention is to provide a pharmaceutical composition for the treatment or prevention of levodopa-induced dyskinesia.
- An object of the present invention is to provide a method for treating or preventing levodopa-induced dyskinesia.
- the GLP-1 receptor agonist (Glucagon-like peptide-1 receptor agonist) of the present invention includes a GLP-1 analog, and more specifically, exendin-4, exenatide, liraglutide, semaglutide , Lixisenatide, duraglutide, albiglutide, epeglenatide, or a combination thereof may be included, but are not limited thereto.
- the controlled-release formulation of the present invention includes a core comprising a GLP-1 receptor agonist and a biodegradable polymer; And a coating layer of this core.
- the biodegradable polymer of the present invention is polylactide, polyglycolide, poly(lactide-co-glycolide), a copolymer of lactide and glycolide, polyorthoester, polyanhydride, polyhydroxybutyric acid.
- a polymer selected from the group consisting of polycaprolactone and polyalkyl carbonate, or a copolymer or mixture of two or more of the polymers, a copolymer of the polymer and polyethylene glycol, and a polymer in which the polymer or copolymer and sugar are bonded -It may be selected from the group consisting of sugar complexes.
- treatment is a concept including improvement in symptoms of levodopa-induced dyskinesia or no further worsening of symptoms.
- prevention is a concept that includes preventing or delaying onset of levodopa-induced dyskinesia despite administration of levodopa.
- the pharmaceutical composition of the present invention has the effect of improving abnormal involuntary movements (AIMs), and the pharmaceutical composition of the present invention has the effect of reducing the side effects of long-term administration of levodopa when administered in combination with levodopa.
- AIMs abnormal involuntary movements
- the present invention provides a method of treating levodopa-induced dyskinesia comprising administering a therapeutically effective amount of a GLP-1 receptor agonist or a controlled-release formulation thereof to a patient with levodopa-induced dyskinesia.
- the present invention provides a method for preventing levodopa-induced dyskinesia comprising administering a prophylactically effective amount of a GLP-1 receptor agonist or a controlled-release preparation thereof to a Parkinson's disease patient who does not develop levodopa-induced dyskinesia. .
- both patients with levodopa-induced dyskinesia and Parkinson's patients who do not develop levodopa-induced dyskinesia may all be patients receiving levodopa.
- the GLP-1 receptor agonist or a controlled-release preparation thereof may be administered simultaneously with levodopa or after administration of levodopa.
- the therapeutically effective amount of the active ingredient in the treatment method of the present invention may be from 0.01 ⁇ g/kg/day to 100 ⁇ g/kg/day.
- a prophylactically effective amount of the active ingredient may be 0.01 ⁇ g/kg/day to 100 ⁇ g/kg/day.
- the GLP-1 receptor agonist includes a GLP-1 analog, and more specifically, exendin-4, exenatide, liraglutide, semaglutide, lixisenatide, duraglu Tide, albiglutide, epeglenatide, or a combination thereof may be included, but are not limited thereto.
