[0009] Incorporation by Reference

[0010] All publications, patents, patent applications and other documents cited in this application are hereby incorporated by reference in their entireties for all purposes to the same extent as if each individual publication, patent, patent application or other document were individually indicated to be incorporated by reference for all purposes. In the event that there are any inconsistencies between the teachings of one or more of the references incorporated herein and the present disclosure, the teachings of the present specification are intended. Background

[0011] Parkinson's disease (PD) is the second most important neurodegenerative disorder in humans. The main risk factor of PD is aging. With an increasing life expectancy worldwide, PD is expected to increase dramatically within the next few years. As an example of this, the World Health Organization indicates that the prevalence of PD has doubled in the past 25 years, and global estimates in 2019 showed over 8.5 million individuals with PD. Current estimates suggest that, in 2019, PD resulted in 5.8 million disability adjusted life years (DALYs), an increase of 81% since 2000, and caused 329 000 deaths representing an increase of over 100% since 2000. PD and other neurodegenerative diseases (called Synucleinopathies or a- Synucleinopathies) result from the progressive accumulation of aberrant forms of the protein called alpha-Synuclein. In PD, alpha-Synuclein self-aggregates to form protein clumps which are toxic for the cells of the brain.

[0012] However, these aggregates appear in early and asymptomatic stages of the disease. In these stages, they are found in the peripheral nervous system, and only after 6 to 8 years of the appearance, they are found in the brain where they cause neuronal death making visible the symptoms of PD. At present, there is no therapy or strategy known, let alone available to patients, to stop the spreading of alpha-Synuclein aggregates and therefore interfere with, or delay or even stop, the progression of PD and other neurodegenerative diseases.

[0013] It is hence one object of the present invention to provide new therapeutic or preventive options for the treatment of neurodegenerative diseases, including a-Synucleinopathies.

[0014] It is another object of the present invention to provide ways to interfere with the accumulation of alpha-Synuclein in neuronal and non-neuronal cells.

[0015] It is another object of the present invention to provide ways to interfere with the aggregation of alpha-Synuclein in neuronal and non-neuronal cells.

[0016] It is another object of the present invention to provide ways to interfere with the spreading of alpha-Synuclein in neuronal and non-neuronal cells. Brief description of the Figures

This refers, particularly, for prior art documents that disclose standard or routine methods. In that case, the incorporation by reference has mainly the purpose to provide sufficient enabling disclosure, and avoid lengthy repetitions.

[0027] According to one aspect of the invention, a ULK1 inhibitor is provided for (the manufacture of a medicament for) use in the treatment of a human or mammalian patient (i) being diagnosed for,

[0028] (ii) suffering from, or

[0029] (iii) being at risk of developing a neurodegenerative disease, or in the prevention of such condition.

[0030] This language is deemed to encompass both the Swiss type claim language accepted in some countries (in this case, brackets are deemed absent) and EPC2000 language (in this case, brackets and content within the brackets is deemed absent).

[0031] The term “neurogenerative disease”, as used herein, relates to diseases caused by the progressive loss of neurons, in the process known as neurodegeneration. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic. Because there is no known way to reverse the progressive degeneration of neurons, these diseases are considered to be incurable, and oftentimes lead to death.

[0032] In one embodiment, the claimed treatment relates to the prevention of a neurodegenerative disease in a human or mammalian patient (i) being diagnosed or (iii) being at risk of developing such disease. The term “prevention”, as used herein, encompasses complete prevention, as well as the amelioration of disease symptoms and the delay of disease onset.

[0033] In one embodiment, the claimed treatment relates to the amelioration and / or reversion of the symptoms of a neurodegenerative disease.

[0034] Unc-51 like kinase 1 (ULK1, also called ATG1, ATG1A, hATGl, UNC51, Unc51.1 or unc-51 like autophagy activating kinase 1) is an enzyme that in humans is encoded by the ULK1 gene.

[0035] ULK1 and ULK2 are two similar isoforms. ULK1 / 2 is an important protein in autophagy for mammalian cells, and is homologous to ATG1 in yeast. It is part of the ULKl-complex, which is needed in early steps of autophagosome biogenesis. The ULK1 complex also consists of the FAK family kinase interacting protein of 200 kDa (FIP200 or RB1CC1) and the HORMA (Hop / Rev7 / Mad2) domain-containing proteins ATG13 and ATG101. ULK1, specifically, appears to be the most essential for autophagy and is activated under conditions of nutrient deprivation by several upstream signals which is followed by the initiation of autophagy. However, ULK1 and ULK2 show high functional redundancy; studies have shown that ULK2 can compensate for the loss of ULK1. Nutrient dependent autophagy is only fully inhibited if both ULK1 and ULK2 are knocked out.

[0036] ULK1 has many downstream phosphorylation targets to aid in this induction of the isolation membrane / autophagosome. Recently, a mechanism for autophagy has been elucidated. Models have proposed that the active ULK1 directly phosphorylates Beclin-1 at Ser 14 and activates the pro-autophagy class III phosphoinositide 3-kinase (PI(3)K), VPS34 complex, to promote autophagy induction and maturation.

[0037] In cancer specifically, ULK1 has become an attractive therapeutic target. Since autophagy acts as a cell survival trait for cells, it enables tumors (once they are already formed) to survive energy deprivation and other stresses such as chemotherapeutics.

[0038] The enzyme is specifically a kinase that is involved with autophagy, particularly in response to amino acid withdrawal. ULK1 is an important protein in autophagy for mammalian cells, and is homologous to ATG1 in yeast.

[0039] ULK1 has many downstream phosphorylation targets to aid in this induction of the isolation membrane / autophagosome. Models have proposed that the active ULK1 directly phosphorylates Beclin-1 at Ser 14 and activates the pro-autophagy class III phosphoinositide 3- kinase (PI(3)K), VPS34 complex, to promote autophagy induction and maturation.

[0040] ULK1 is a 112-kDa protein. It contains a N-terminal kinase domain, a serine-proline rich region, and a C-terminal interacting domain. The serine-proline rich region has been shown experimentally to be the site of phosphorylation by mTORCl and AMPK — a negative and positive regulator of ULK1 activity, respectively. The C-terminal domain contains two microtubule-interacting and transport (MIT) domains and acts as a scaffold which links ULK1, ATG13, and FIFP200 together to form a complex that is essential to initiate autophagy. Early autophagy targeting / tethering (EAT) domains in the C-terminus are arranged as MIT domains consisting of two three-helix bundles. MIT domains also mediate interactions with membranes. The N-terminus contains a serine-threonine kinase domain. ULK1 also contains a large activation loop between the N and C terminus that is positively charged. This region may regulate kinase activity and play a role in recognizing different substrates. ULK1 and ULK2 share significant homology in both the C-terminal and N-terminal domains. ULK1 is phosphorylated by AMPK on Ser317 and Ser777 to activate autophagy; mTOR participates in inhibitory phosphorylation of ULK1 on Ser757. Additionally, ULK1 can autophosphorylate itself at Thrl80 to facilitate self-activation.

[0041] Viral targeting of ULK1 appears to disrupt host autophagy. Coxsackievirus B3 viral proteinase 3C can proteolytically process ULK1 by cleaving after glutamine (Q) residue 524, separating the N-terminal kinase domain from C-terminal early autophagy targeting / tethering (EAT) domain.

[0042] In cancer specifically, ULK1 has become an attractive therapeutic target. Since autophagy acts as a cell survival trait for cells, it enables tumors (once they are already formed) to survive energy deprivation and other stresses such as chemotherapeutics. For that reason, inhibiting autophagy may prove to be beneficial. Thus, inhibitors have been targeted towards ULK1.

[0043] The inventors have shown that the slow spreading of the alpha-Synuclein aggregates from the periphery to the brain is likely to result from to the cell-to-cell propagation of alpha-Synuclein via sequential steps of secretion and uptake. By this mechanism of transmission, alpha- Synuclein aggregates travel from the periphery to the brain using neuroanatomical interconnected areas. The inventors have further shown that the inhibition of ULK1 activity can contribute to stopping or delaying alpha-Synuclein cell-to-cell transmission.

[0044] These findings provide a therapeutic option that could be used to stop the progression of neurodegenerative diseases to stages where symptoms of the disease are still absent.

[0045] According to another aspect of the invention, a method for treating a human or mammalian patient is provided, which method comprises administration of one or more ULK1 inhibitors, wherein the human or mammalian patient

[0046] (i) is diagnosed for,

[0047] (ii) suffers from or

[0048] (iii) is at risk of developing a neurodegenerative disease. According to embodiments of the invention, the ULK1 inhibitor is a small molecular inhibitor selected from the group consisting of AP26113 (Brigatinib) or Hesperadin.

[0049] AP26113 (Brigatinib, CAS number 1197953-54-0) is a highly potent, selective and orally active inhibitor of ALK (anaplastic lymphoma kinase), with an IC50 of 0.6 nM. Brigatinib can be used for research of NSCLC (Camidge et al., 2022). Surprisingly, the inventors of the present invention have for the first shown that (i) Brigatinib is also capable of inhibiting ULK1, and that (ii) administration thereof suppresses the formation of aSyn.

[0050] Hesperadin (CAS number 422513-13-1) is an indolinone inhibitor of Aurora A and B kinase, and has been described to inhibit chromosome alignment and segregation (Hauf et al., 2003). Surprisingly, the inventors of the present invention have for the first shown that (i) Hesperadin is also capable of inhibiting ULK1, and that (ii) administration thereof suppresses the formation of aSyn.

[0051] According to embodiments of the invention, the ULK1 inhibitor is a small molecular inhibitor selected from the group consisting of SBI-0206965 (SB I) and MRT-68921 (MRT).

[0052] SBI-0206965 is a potent, selective and cell permeable autophagy kinase ULK1 inhibitor with IC50s of 108 nM for ULK1 kinase and 711 nM for the highly related kinase ULK2.

[0053] MRT-68921 is a potent inhibitor of ULK1 and ULK2, with IC50 values of 2.9 nM and 1.1 nM, respectively.

[0054] According to another embodiment of the invention, the ULK1 inhibitor is Dabrafenib. Dabrafenib (GSK2118436A) is an ATP-competitive inhibitor of Raf with IC50S of 5 nM and 0.6 nM for C-Raf and B-RafV600E, respectively. It has been shown to inhibit ULK1 (Phadke et al., 2018)

[0055] According to embodiments of the invention, the ULK1 inhibitor is a small molecular inhibitor selected from the list shown in table 1.

[0056] Again, it needs to be emphasized that contrary to the existing opinion in the art, namely that activation of ULK1 would enhance autophagy and as such has a therapeutic potential on neurodegenerative diseases like Parkinson’s disease, for instance by reducing aSyn aggregates, the inventors show herein that inhibition of ULK1 can open up new and efficacious ways to treat and / or prevent neurodegenerative diseases.

[0057] According to embodiments of the invention, the neurodegenerative disease is caused by accumulation of alpha-Synuclein.

[0058] Alpha-synuclein (aSyn) is a protein that, in humans, is encoded by the SNCA gene. Alpha- synuclein is a neuronal protein that regulates synaptic vesicle trafficking and subsequent neurotransmitter release. It is abundant in the brain, while smaller amounts are found in the heart, muscle and other tissues. In the brain, alpha-synuclein is found mainly in the axon terminals of presynaptic neurons. Within these terminals, alpha-synuclein interacts with phospholipids and proteins. Presynaptic terminals release chemical messengers, called neurotransmitters, from compartments known as synaptic vesicles. The release of neurotransmitters relays signals between neurons and is critical for normal brain function.

[0059] Neurodegenerative diseases caused by accumulation of alpha-Synuclein are also called Synucleinopathies or a-Synucleinopathies). The terms can be used interchangeably.

[0060] In these diseases, insoluble forms of alpha-synuclein accumulate in neuron cells, e.g., as inclusions in Lewy bodies. There are three main types of synucleinopathies: Parkinson's disease (PD), dementia with Lewy bodies (DLB), and multiple system atrophy (MSA), yet also other rare disorders, such as various neuroaxonal dystrophies. Additionally, autopsy studies have shown that a significant share of Alzheimer's Disease patients exhibit a-synuclein positive Lewy pathology, and are sub-classed as Alzheimer's Disease with Amygdalar Restricted Lewy Bodies (AD / ALB) (Hamilton 2000). Further, evidence exists that a-synuclein can contribute to the pathogenesis of amyotrophic lateral sclerosis (ALS) (Fyfe, 2024).

[0061] The inventors have surprisingly shown that ULK1 inhibition reduces accumulation of cell-to- cell transmitted alpha-Synuclein (aSyn) as well as wild type alpha-Synuclein. Without being bound to theory, this could be caused by inhibition of alpha-Synuclein secretion. As such, the inventors have provided a new therapeutic option to address, prevent and / or treat neurodegenerative diseases that are real. ULK1 is a master regulator of autophagy. ULK1 activation leads to activation of autophagy, whereas ULK1 inhibition leads to autophagy reduction.

[0062] In the prior art, some small-molecule agents that enhance autophagic activity have been described to have therapeutic potential on neurodegenerative diseases like Parkinson’s disease, for instance by reducing aSyn aggregates.

[0063] These include Latrepirdine, a neuroactive compound, can reduce aSyn accumulation in mouse neurons by stimulating autophagy (Steele et al., 2013). Isorhynchophylline was found to activate autophagy and expedite the degradation of aggregated aSyn in neuron cells (Lu et al., 2012). Trehalose is also an autophagic regulator to accelerate the clearance of aSyn in a PD model (Sarkar et al., 2007). PD180970 is a small molecule modulator of aggrephagy that regulates neuroinflammation to curb pathogenesis of neurodegeneration. PD 180970 clears toxic protein oligomers by inducing autophagy in the substantia nigra pars compacta, and mitigates neuronal loss in animal models of Parkinson’s disease such as the MPTP induction (Sn et al., 2019).

[0064] Autophagy, a mechanism of protein aggregate clearance, is activated by ULK1 activation. According to the art, therapies based on ULK1 activation (rather than inhibition) were proposed to clear aggregates. As such, ULK1 activation has been proposed to be a therapeutic opportunity for neurological disorders with protein aggregation aetiology.

[0065] Gao et al. (2019) showed that GSK621 and A769662 are two compounds that activate AMPK and ULK1 (Dong and Yang, 2024; Gao et al., 2019). Both compounds were considered to also induce autophagy pathway in SH-SY5Y cells, and to reduce levels of aSyn inclusions at 6 days post-PFF treatment. Therefore, ULK1 activation by these two AMPK / ULK1 activators has been proposed for the treatment of Parkinson’s disease.

[0066] Liu et al. (2023) demonstrated that BL-918, also called 33i is an ULK1 activator that induce cytoprotective autophagy via the ULK complex in human neuroblastoma SH-SY5Y cells as well as in mice. In this line, silencing of ULK1 or blocking autophagy induction lead to a decreased level of cytoprotective autophagy. BL-918 exerts its neuroprotective effects by increasing ULK 1 -modulated autophagy in vitro as well as in a MPTP-induced Parkinson’s disease mouse model, which is characterized by significant reduction in the loss of TH-positive neuron cells and MPTP-induced apoptosis. Importantly, due to its low molecular weight, BL- 918 may transport well across the blood-brain barrier and enter into the brain, thus making it a leading compound for PD drug development (Ouyang et al., 2018). BL-918 activates ULK1- dependent autophagy in vitro and induces cytoprotective autophagy by eliminating toxic superoxide dismutase 1 (SOD1) aggregates. Thus, the ULK1 activator BL-918 was considered to have therapeutic potential on SOD and protein aggregation-related diseases.

[0067] ULK1 expression can also be altered by the action of microRNAs, and the regulatory role of a variety of microRNAs in Parkinson’s disease has been reported. For instance, Lv et. al. (2021) demonstrated that miR-3473b target TREM2 / ULK1 expression to regulate the role of autophagy in the pathogenesis of inflammation in Parkinson's disease (Lv et al., 2021). They proposed that miR-3473b directly and indirectly decreases TREM2 and ULK1 expression, which both result in reduced autophagy. Conversely, blocking mir-3473b by exogenous delivery of an antagomir increase the expression of TREM2 and ULK1 in MPTP -treated mouse substantia nigra pars compacta in vivo leading to increased autophagy. Exogenous mir-3473b antagomir enhances the effects of MPTP treatment on TREM2 and P-ULK1 in the midbrain of mice to inhibit the activation of microglia and promote autophagy. This result suggests that mir- 3473b can target TREM2 and indirectly regulate the inflammatory response of microglia mediated by ULK1, which may be a candidate target for therapy in the inflammatory pathogenesis of PD.

[0068] Vasconcelos-Ferreira et al. (2022) showed that ULK1 / 2 overexpression reduces the toxic forms of mutATXN3 in the lentiviral-based mouse model of Machado-Joseph disease. ULK1 exerts an essential role in autophagy -mediated mutATXN3 clearance in vitro. ULK1 and ULK2 promoted a significant decrease of high-MW species, soluble mutATXN3, and 34-kDa fragment levels by 67.44% ± 7.21%, 88.45% ± 7.75%, and 68.81% ± 14.59%, respectively. Furthermore, upon immunohistochemistry, the quantification of the number of ubiquitinpositive inclusions further revealed a similar significant reduction upon ULK1 / 2 overexpression (37.78% ± 6.50% versus 100% ± 20.99% control). Thus, overexpression of ULK homologs has been proposed as a promising instrument for the treatment of Machado- Joseph disease and other neurodegenerative disorders.

[0069] (Lim et al., 2015) showed that ULK1 activation, through Phosphorylation of p62 at S409, potentiates autophagic degradation of polyQ-expanded Huntingtin (Htt) mutant. The presence of ULK1 and p62 p-S405 and p-S409 in poly-Ubiquitin (Ub) or polyQ-expanded protein aggregates causes the recruitment of autophagy machinery that is responsible for the degradation of poly-Ub or polyQ-Htt mutant proteins. ULKl-mediated phosphorylation of p62 is likely activated by mechanisms distinct from canonical nutrient pathways. Instead, it may involve sensing of proteotoxic stresses such as accumulation of misfolded poly-ubiquitinated proteins or disease-related protein aggregates. Their results thus provide a rationale for the development of therapeutics against human diseases associated with protein aggregates(proteinopathies), based on ULK1 activation and targeting p62 for phosphorylation.

[0070] There are patents related to increased autophagy by ULK1 activation as treatment for neurodegenerative diseases such as Parkinson’s disease. For instance, China patent CN106748892A related to target autophagy activator and its application in neurodegenerative disease therapeutic agent by an ULK1 activator. International application WO2018133756A1 related to target autophagy activator and its application in neurodegenerative disease therapeutic agent by an ULK1 agonist.

[0071] There are several patents related to autophagy activation for the treatment of neurodegenerative diseases, including Parkinson’s disease (PD). Autophagy is a crucial cellular process that removes damaged proteins and organelles, and its dysfunction is implicated in Parkinson’s disease pathology (Zhang et al., 2015).

[0072] US patent USS9005677B2 relates to autophagy enhancers for the treatment of neurodegenerative diseases and discloses the use and application of Onjisaponin B derived and isolated from Radix polygalae as novel autophagy enhancer. It further discloses a method of preventing, treating and / or delaying the onset of neurodegenerative diseases comprising administering an effective amount of Onjisaponin B is also provided.

[0073] US patent US9351946B2 relates to MTOR-independent activators of TFEB for autophagy enhancement and uses thereof, it discloses a composition comprising an autophagy enhancement compound. Small molecules that are able to enhance autophagy and lysosome biogenesis by activating the gene TFEB which can prevent the accumulation of toxic protein aggregates in treating neurodegenerative diseases are disclosed. US application US20210136626A1 relates to methods of treatment of neurodegenerative diseases through autophagy activation, and discloses the treatment of neurodegenerative diseases such as Parkinson's by activating autophagy with specific compounds.

[0074] International application W02020030158A relates to autophagy-activating compounds and uses thereof. It describes small molecules that induce autophagy and suggests potential uses in treating neurodegenerative diseases like Parkinson’s.

[0075] US patent US10851036B2 relates to small molecules for autophagy modulation and their use in neurodegenerative disorders. It discusses small molecule autophagy modulators and their therapeutic applications in diseases like Parkinson’s.

[0076] However, it appears that these approaches were not successful though. Without being bound to theory, reasons for the failure might be that autophagy is pleiotropic, and when aggregates accumulate it is already too late to treat the disease.

[0077] Parkinson’s disease is characterized by a massive loss of dopaminergic neurons in the substantia nigra. This neuronal loss results from the accumulation of neurotoxic alpha-Synuclein aggregates in this brain structure. Several cellular and animal models of Parkinson’s disease were generated by mimicking this effect with toxins that damage dopaminergic neurons such as the toxin l-methyl-4-phenyl-l,2,3,6-tetrahydropyridine (MPTP) that appears to target and lesion relatively specifically those neurons that are involved in Parkinson's disease. Thus, MPTP-derived lesions have been used as cellular and animal models of Parkinson's disease.

[0078] All previous studies fail to show any effect of ULK1 inhibition or reduced function on alpha- Synuclein or the aggregates.

[0079] As such, the inventors of the present invention have surprisingly shown that ULK1 inhibition targets alpha-Synuclein or the cell-to-cell transmitted alpha-Synuclein (made by sp2-aSyn) or in general alpha-Synuclein aggregates. The inventors have thus revealed a new way of interfering with the generation of the neurodegenerative diseases. According to embodiments of the invention, the neurodegenerative disease is at least one selected from the group consisting of

[0080] • Alzheimer’s Disease (AD)

[0081] • dementia with Lewy bodies (DLB)

[0082] • multiple system atrophy (MSA)

[0083] • Parkinson’s Disease (PD), and / or

[0084] • Amyotrophic Lateral Sclerosis (ALS)

[0085] In one embodiment, Alzheimer's Disease is Alzheimer's Disease with Amygdalar Restricted Lewy Bodies (AD / ALB).

[0086] According to embodiments of the invention, the ULK1 inhibitor is at least one of

[0087] • a DNA or RNA oligonucleotide targeting the ULK1 capable of activating the RNA interference pathway, like e.g. an shRNA or an siRNA,

[0088] • a small molecular inhibitor,

[0089] • a moiety that is capable to directly or indirectly reduce the expression of the ULK1 gene, like e.g. a moiety encompassing or encoding inter alia a programmable endonuclease, and / or

[0090] • a monoclonal antibody, or a target binding fragment thereof.

[0091] RNA interference (RNAi) is the process by which the expression of a target gene is effectively silenced or knocked down by the selective inactivation of its corresponding mRNA by doublestranded RNA (dsRNA). RNAi is activated by dsRNA species delivered to the cytoplasm of cells. The silencing mechanisms can either lead to the degradation of a target mRNA, as induced by small interfering RNAs (siRNAs) or short hairpin RNAs (shRNAs), or the suppression of translation of specific mRNAs, as induced by microRNA (miRNA).

[0092] In siRNA technology, dsDNA consisting of a sense strand identical to the target sequence and an antisense strand, each of which having a 2 nt 3’ overhang, is transfected into a cell, where it is incorporated into the RISC, which is composed of Argonaute-2 (Ago-2), Dicer, and TAR- RNA-binding protein (TRBP). The RNA duplex is separated, and one strand is removed from the complex. The strand with the lowest duplex stability at its 5'-end is selected for stable incorporation into the RISC. In shRNA technology, a dsDNA is transfected into a cell by means of a suitable vector. The dsDNA comprises, in 5 ’->3’ direction, a sense strand identical to the target sequence, a loop structure and an antisense strand. pre-shRNA is then synthesized in the nucleus of the transfected cells by RNA pol II or III transcription, and form hairpin structures that consist of a stem region of paired antisense and sense strands connected by unpaired nucleotides that make up a loop. The pre-shRNA is processed Drosha, which is an RNase III enzyme and its dsRNA- binding partner DGCR8, to obtain shRNA. shRNAs are then exported by Exportin-5 to the cytoplasm where they associate with Dicer, resulting in the removal of the loop sequence. From this point, they are processed in the same manner as siRNAs, meaning that they are incorporated into RISC.

[0093] Once loaded onto the RISC, the process of target mRNA recognition and degradation by both shRNA and siRNA is essentially the same. As a moiety of the RISC, the siRNA binds to the target mRNA in a sequence-specific manner that is mediated by complementary base pairing, leading to cleavage of the target RNA phosphate backbone near the center of the duplex via the action of the RNase-H like activity of Ago-2. An interesting feature of this system in some organisms is that annealing of the siRNA to the target mRNA allows the siRNA to act as a primer, while the target mRNA acts as a template for an RNA-dependent RNA-polymerase. This creates a new dsRNA, which is then processed by Dicer, creating a positive feedback loop that increases the pool of siRNAs.

[0094] In order to design dsDNA molecules that can then be used either for shRNA- or siRNA based gene silencing the sequence of the target gene is necessary. Based thereon, the skilled artisan can then a) define a target sequence within the target gene, and b) define sequence stretches to design dsDNA which can then be used for shRNA- or siRNA based gene silencing.

[0095] Small molecule inhibitors in the meaning of this patent are inhibitors that reduce or ULK1 activity. The skilled person is able to determine ULK1 inhibition of candidate molecules by means of suitable assays, like e.g. the ULK1 Kinase Assay ADP-Glo™ Kinase Assay (Application Notes Ser-Thr Kinase Series: ULK1) manufactured by Promega. In several embodiments, these inhibitors are Tyrosin kinase inhibitors. Examples for small molecular inhibitors are shown in the following table:

[0096] Table 1: Examples for small molecular inhibitors

[0097] A moiety that is capable to directly or indirectly reduce the expression of the ULK1 gene, like e.g., a moiety encompassing or encoding inter alia a programmable endonuclease, is for example a vector, or a Lipid nanoparticle (LNP), comprising a nucleotide sequence (e.g., an mRNA) encoding for a CRISPR Cas9 enzyme and a suitable guide RNA (gRNA or sgRNA), so as to cleave within the ULK1 gene (Kazemian et al. 2022)). Other programmable endonucleases encompass Casl2a / Cpfl, CasX, CasLambda, TALEN, ZinkFinger and so forth (Wang et al. 2016).

[0098] Finding the right sequence for the guide RNA to cleave within the ULK1 gene is a matter of routine for the skilled artisan.

[0099] An “antibody” refers to a molecule of the immunoglobulin family comprising a tetrameric structural unit. Each tetramer is composed of two identical pairs of polypeptide chains, each pair having one “light” chain (about 25 kD) and one “heavy” chain (about 50-70 kD), connected through a disulfide bond. Recognized immunoglobulin genes include the K, , a, y, 5, a, and p constant region genes, as well as the myriad immunoglobulin variable region genes. Light chains are classified as either K or . Heavy chains are classified as y, p, a, 5, or a, which in turn define the immunoglobulin classes, IgG, IgM, IgA, IgD, and IgE, respectively. Antibodies can be of any isotype / class (e.g., IgG, IgM, IgA, IgD, and IgE), or any subclass (e.g., IgGl, IgG2, IgG3, IgG4, IgAl, IgA2).

[0100] Both the light and heavy chains are divided into regions of structural and functional homology. The terms “constant” and “variable” are used structurally and functionally. The N-terminus of each chain defines a variable (V) region or domain of about 100 to 110 or more amino acids primarily responsible for antigen recognition. The terms variable light chain (VL) and variable heavy chain (VH) refer to these regions of light and heavy chains respectively. The pairing of a VH and VL together forms a single antigen-binding site. In addition to V regions, both heavy chains and light chains contain a constant (C) region or domain. A secreted form of an immunoglobulin C region is made up of three C domains, CHI, CH2, CH3, optionally CH4 (Cp), and a hinge region. A membrane-bound form of an immunoglobulin C region also has membrane and intracellular domains. Each light chain has a VL at the N-terminus followed by a constant domain (C) at its other end. The constant domains of the light chain (CL) and the heavy chain (CHI, CH2 or CH3) confer important biological properties such as secretion, transplacental mobility, Fc receptor binding, complement binding, and the like. By convention, the numbering of the constant region domains increases as they become more distal from the antigen binding site or amino-terminus of the antibody. The N-terminus is a variable region and at the C-terminus is a constant region; the CH3 and CL domains actually comprise the carboxy-terminal domains of the heavy and light chain, respectively. The VL is aligned with the VH and the CL is aligned with the first constant domain of the heavy chain. As used herein, an “antibody” encompasses conventional antibody structures and variations of antibodies. Thus, within the scope of this concept are full length antibodies, chimeric antibodies, humanized antibodies, human antibodies, and antibody fragments thereof.

[0101] Antibodies exist as intact immunoglobulin chains or as a number of well-characterized antibody fragments produced by digestion with various peptidases. The term “antibody fragment,” as used herein, refers to one or more portions of an antibody that retain the ability to specifically interact with (e.g., by binding, steric hindrance, stabilizing / destabilizing, spatial distribution) an epitope of an antigen. Thus, for example, pepsin digests an antibody below the disulfide linkages in the hinge region to produce F(ab)’2, a dimer of Fab’ which itself is a light chain joined to VH-CH1 by a disulfide bond. The F(ab)’2 may be reduced under mild conditions to break the disulfide linkage in the hinge region, thereby converting the F(ab)’2 dimer into a Fab’ monomer. The Fab’ monomer is essentially Fab with part of the hinge region. While various antibody fragments are defined in terms of the digestion of an intact antibody, one of skill will appreciate that such fragments may be synthesized de novo either chemically or by using recombinant DNA methodology. As used herein, an “antibody fragment” refers to one or more portions of an antibody, either produced by the modification of whole antibodies, or those synthesized de novo using recombinant DNA methodologies, that retain binding specificity and functional activity. Examples of antibody fragments include Fv fragments, single chain antibodies (ScFv), Fab, Fab', Fd (Vh and CHI domains), dAb (Vh and an isolated CDR); diabodies and single chain diabodies; and multimeric versions of these fragments (e.g., F(ab')2.) with the same binding specificity. Antibody fragments can also be incorporated into cytokine engrafted proteins to achieve the binding specificity and activity provided in the present disclosure.

[0102] A "Fab" domain as used herein comprises a heavy chain variable domain, a constant region CHI domain, a light chain variable domain, and a light chain constant region CL domain. The interaction of the domains is stabilized by a disulfide bond between the CHI and CL domains. In some embodiments, the heavy chain domains of the Fab are in the order, from N-terminus to C-terminus, VH-CH and the light chain domains of a Fab are in the order, from N-terminus to C-terminus, VL-CL. In some embodiments, the heavy chain domains of the Fab are in the order, from N-terminus to C-terminus, CH-VH and the light chain domains of the Fab are in the order CL-VL. Although Fabs were historically identified by papain digestion of an intact immunoglobulin, in the context of this disclosure, a “Fab” is typically produced recombinantly by any method. Each Fab fragment is monovalent with respect to antigen binding, i.e., it has a single antigen- binding site.

[0103] Methods for the production of a hybridoma cell and momoclonal antibodies are disclosed in Kohler & Milstein (1975). Methods for the production and / or selection of fully human mAbs are known in the art. These can involve the use of a transgenic animal which is immunized with the respective protein or peptide, or the use of a suitable display technique, like yeast display, phage display, B-cell display or ribosome display, where antibodies from a library are screened against CD2 in a stationary phase. In vitro antibody libraries are, among others, disclosed in US6300064 by MorphoSys and US6248516 by MRC / Scripps / Stratagene. Phage Display techniques are for example disclosed in US5223409 by Dyax. Transgenic mammal platforms are for example described in EP1480515A2 by Taconic Artemis. IgG, IgM, scFv, Fab and / or F(ab)2 are antibody formats well known to the skilled person. Related enabling techniques are available from the respective textbooks, and respective terms are described in, for example, Huston et al., (1993) or Pliickthun and Skerra (1990).

[0104] Antibodies capable of binding to ULK1 are commercially available, as shown in the following table:

[0106] For intracellular applications, the antibody can either be delivered intracellularly, for example by means of antibody -peptide fusions (Gaston et al., 2019) or by delivery of mRNA encoding for an anti ULK1 antibody (Zhao et al., 2023).

[0114] EXAMPLES

[0115] While the invention has been illustrated and described in detail in the drawings and foregoing description, such illustration and description are to be considered illustrative or exemplary and not restrictive; the invention is not limited to the disclosed embodiments. Other variations to the disclosed embodiments can be understood and effected by those skilled in the art in 777444 Examples

[0116] Example 1: RNA interference (shRNA) mediated inhibition of ULK1 gene expression reduces accumulation of aSyn

[0117] A variant of alpha-Synuclein (aSyn) that is cell-to-cell transmitted was developed. This variant is called sp2-aSyn (Prymaczok et al, 2024) In contrast, an intracellular form of this protein is called wt-aSyn. It has been shown that wt-aSyn can also be cell-to-cell transmitted but at much lesser extent than sp2-aSyn.

[0118] An shRNA which targets the sequence 5 ' TGGAGCAAGAGCACACGGA ' 3 (SEQ ID NO: 1) contained in the genes encoding human and Mus musculus ULK1 was prepared. This sequence is found as 5 ' UGGAGCAAGAGCACACGGA ' 3 (SEQ ID NO: 7) within the mRNA transcripts encoding human and Mus musculus ULK1, as well as the siRNA generated by this shRNA.

[0119] In order to create the desired shRNA, a single-stranded DNA oligonucleotide of sequence

[0120] 5 ' GATCCCTGGAGCAAGAGCACACGGATTCAAGAGATCCGTGTGCTCTTGCTCCATTT

[0121] TA' 3 (SEQ ID NO: 5) was annealed with a single-stranded DNA oligonucleotide of sequence

[0122] 5 ' AGCTTAAAATGGAGCAAGAGCACACGGATCTCTTGAATCCGTGTGCTCTTGCTCCA GG ' 3 . (SEQ ID NO: 6).

[0123] See Figure 5 for an illustration.

[0124] The resulting double-stranded DNA oligonucleotide was then inserted by standard cloning procedures into the plasmid pSUPERIOR™. In this way an shRNA / siRNA targeting mRNA transcripts containing the sequence 5 ' UGGAGCAAGAGCACACGGA ' 3 (SEQ ID NO: 7) is expressed in mammalian cells upon intracellular delivery of the recombinant plasmid. To effect the silencing of a specific gene, the pSUPERIOR vector is used in concert with a pair of custom oligonucleotides that contain, among other features, a unique 19-nt sequence derived from the mRNA transcript of the gene targeted for suppression (the “N-19 target sequence”).

[0125] The N-19 target sequence corresponds to the sense strand of the pSUPERIOR-gen erated siRNA, which in turn corresponds to a 19-nt sequence within the mRNA. In the mechanism of RNAi, the antisense strand of the siRNA duplex hybridizes to this region of the mRNA to mediate cleavage of the molecule. These forward and reverse oligos are annealed and cloned by the user into the vector, between the unique Bglll and Hindlll enzyme sites. This positions the forward oligo at the correct position downstream from the Hl promoter’s TATA box to generate the desired siRNA duplex. The sequence of this forward oligo includes the unique N- 19 target in both sense and antisense orientation, separated by a 9-nt spacer sequence.

[0126] The 5’ end corresponds to the Bglll site, while the 3’ end contains the T5 sequence and any Hindlll-corresponding nucleotides. NOTE that while the 5’ overhang of the oligo corresponds to the 3’ Bglll overhang of the plasmid, the overhang sequence of the oligo actually corresponds to the BamHl, and thus destroys the Bglll site upon ligation to enable more efficient screening of positive clones. The resulting transcript of the recombinant vector is predicted to fold back on itself to form a 19-base pair stem-loop structure. Analysis indicates that the stem-loop precursor transcript is quickly cleaved in the cell to produce a functional siRNA.

[0127] Additionally, we have used siRNAs for ULK1 gene silencing. The siRNA targets the sequence 5’TCATGGAGCAAGAGCACACGGA‘3 (SEQ ID NO: 2) within the genes encoding human and Mus musculus ULK1.

[0128] The preparation of the shRNA is illustrated in Figure 5. Based on this information already, the skilled artisan is able to design suitable siRNA molecules or shRNA molecules able to interfere with gene expression of ULK1, even if other target sequences of ULK1 are addressed.

[0129] Figure 1 shows a Western blot obtained from whole cell lysates of Cos7 transfected with plasmids encoding GFP (control protein), wt-aSyn or the secreted sp2-aSyn. The cells were cotransfected with the pSUPERIOR vector encoding a control shRNA (shLUC, lanes 1-3) or an shRNA against ULK1 (shULKl, lanes 4-6). Reduction of ULK1 protein levels by shULKl are shown in the corresponding blot (labelled ULK1). Reduction of levels of high-molecular weight (HMW) and monomeric (14 KDa) aSyn by shULKl are shown in the blot labelled WB: aSyn. HMW aSyn are meta-stable aggregates that resist sample treatment for Western blot sample preparation.

[0130] Example 2 and 3: Pharmacological inhibition of ULK1 function

[0131] Reduced activity of ULK1 can also be achieved by pharmacological inhibition. We have used two ULK1 inhibitors to inhibit accumulation of wt-aSyn and sp2-aSyn.

[0132] Mammalian cells were transfected with plasmids encoding GFP (control protein), wt-aSyn or the secreted sp2-aSyn. After transfection the cells were treated with the ULK1 inhibitors SBI- 0206965 (SBI) for 16 h (Example 2) or MRT-68921 (MRT) (Example 3). After treatment the cells were harvested and the corresponding cell lysates were analyzed by WB using the indicated antibodies. 0, vehicle-treated cells. HMW high molecular weight species such as meta-stable aSyn aggregates that remain as HMW even after the sample treatment for Western blot. Results are shown in Figures 2 and 3.

[0133] Example 4: RNA interference (siRNA) mediated inhibition of ULK1 gene expression reverses the reduced cell viability in wt- and sp2-«Syn expressing cells

[0134] A commercially-available siRNA which targets the sequence 5 ' TCATGGAGCAAGAGCACACGGA ' 3 (SEQ ID NO: 2) contained in the genes encoding human and Mus musculus ULK1 was purchased and transfected in cells expressing GFP (control) or wt- or sp2-aSyn. A control siRNA (siLUC) was transfected similarly. After transfection cell viability was determined using the MTT test.

[0135] Data is shown as the media ± SD. * p < 0.05 compared to GFP-expressing cells (one-way ANOVA followed by the post hoc Dunnett’s test).

[0136] Results show that in cells transfected with an unrelated siRNA called siLUC, both wt- and sp2- aSyn expressing cells display a statistically significant reduction of cell viability when compared to cells expressing the control protein GFP (Figure 4, bars 2 and 3 versus bar 1). In cells transfected with an siRNA against ULK1 (siULKl), this reduction in cell viability is not observed. Results are shown in Figure 4. Example 5: RNA interference (siRNA) mediated inhibition of ULK1 gene expression reduces the levels of BMW of wt- and sp2-aSyn

[0137] A commercially-available siRNA which targets the sequence 5 ' TCATGGAGCAAGAGCACACGGA ' 3 (SEQ ID NO: 2) contained in the genes encoding human and Mus musculus ULK1 was purchased and transfected in cells expressing GFP (control) or wt- or sp2-aSyn. A control siRNA (siLUC) was transfected similarly. After transfection the cells were harvested and whole cell lysates were analysed by Western blot using the indicated antibodies.

[0138] Results show that in cells transfected with an unrelated siRNA called siLUC, the levels of both wt- and sp2-aSyn are higher than in cells transfected with an siRNA against ULK1 (siULKl). In this experiment in particular, the effect of ULK1 silencing is observed in the high molecular weight species (BMW) of aSyn (WB: aSyn, HMW upper part, lane 5 versus lane 2, and lane 6 versus lane 3). It can be seen that a reduction of ULK1 protein levels by siULKl (WB: ULK1, lanes 4-6 versus 1-3) has been achieved. Results are shown in Figure 6.

[0139] Example 6: Efficacy of AP-26113 (Brigatinib) and Hesperadin

[0140] Cos7 cells were transiently transfected with an expression vector encoding sp2-aSyn. 24h post transfection the cells were treated with DMSO (Vehicle), or three different doses of AP-26113 (Brigatinib) or Hesperadin. (1000, 100 and 10 nanoMolar). 24h later the cells were harvested and whole cell lysates were analysed by Western blot using the indicated antibodies. The GAPDH blot is used as loading control. Dashed line indicates the upper part of the gel were high-molecular weight species (HMW) are retained.

[0141] It can be seen that both AP-26113 (Brigatinib) and Hesperadin reduce the formation of sp2- aSyn in the transfected cells. Results are shown in Figure 7.
