Therefore, in some embodiments, biomarkers are predictions of neurodegenerative diseases, disorders or conditions, in some embodiments, biomarkers are prognoses of neurodegenerative diseases, disorders or conditions, and in some embodiments, biomarkers are diagnoses of neurodegenerative diseases, disorders or conditions. In some embodiments, changes in biomarker levels can be detected by cerebrospinal fluid (CSF), plasma and / or serum.

[0053] In some embodiments, neurodegeneration can be assessed, for example, by detecting an increase and / or decrease in the concentration of neurofilament light chain (NF-L) and / or neurofilament heavy chain (NF-H) in the cerebrospinal fluid of a subject. In some embodiments, the occurrence and / or progression of neurodegeneration can be assessed by positron emission tomography (PET) with synaptic vesicle glycoprotein 2a (SV2A) ligand. In some embodiments, detectable changes in constitutive NAD and / or cADPR levels in neurons can be used to assess neurodegeneration.

[0054] In some embodiments, relative to a healthy reference population, a detectable change in one or more neurodegeneration-related proteins in a subject can be used as a biomarker for neurodegeneration. Such proteins include, but are not limited to, albumin, amyloid-β (Aβ) 38, Aβ40, Aβ42, glial fibrillary acidic protein (GFAP), heart-type fatty acid binding protein (hFABP), monocyte chemoattractant protein (MCP) -1, neurogranulin, neuron-specific enolase (NSE), soluble amyloid precursor protein (sAPP) α, sAPPβ, soluble triggering receptor expressed on myeloid cells (sTREM) 2, phosphorylated tau and / or total tau.

In some embodiments, such an amount is a unit dose (or a fraction thereof) suitable for administration according to a dosing regimen (i.e., a therapeutic dosing regimen) that has been determined to be associated with a desired or beneficial outcome when administered to a relevant population. It will be understood by those of ordinary skill in the art that the total amount of a therapeutic composition or medicament administered to a particular subject is determined by one or more attending physicians and may involve the administration of multiple dosage forms.

[0060] Dosing regimen or therapeutic regimen: Those skilled in the art will appreciate that the terms "dosing regimen" and "therapeutic regimen" can be used to refer to a group of unit doses (usually more than one) administered individually to a subject, the unit doses typically being separated by time periods. In some embodiments, a given therapeutic agent has a recommended dosing regimen, which may involve one or more doses. In some embodiments, the dosing regimen includes multiple doses, each separated in time from the other doses. In some embodiments, each dose is separated from another by a time period of the same length; in some embodiments, the dosing regimen includes multiple doses and at least two different time periods separating each dose. In some embodiments, all doses within a dosing regimen have the same unit dose amount. In some embodiments, different doses within a dosing regimen have different amounts. In some embodiments, a dosing regimen comprises a first dose in the amount of the first dose, followed by one or more additional doses in the amount of a second dose that is different from the amount of the first dose. In some embodiments, a dosing regimen comprises a first dose in the amount of the first dose, followed by one or more additional doses in the amount of the second dose that is the same as the amount of the first dose. In some embodiments, a dosing regimen is associated with a desired or beneficial outcome when administered to a relevant population (i.e., is a therapeutic dosing regimen).

DETAILED DESCRIPTION

[0079] Programmed axonal degeneration and SARM1

[0080] Axonal degeneration is a major pathological feature of neurological diseases, such as, but not limited to, Alzheimer's disease, Parkinson's disease, ALS, multiple sclerosis, diabetic peripheral neuropathy, chemotherapy-induced peripheral neuropathy, hereditary neuropathy, traumatic brain injury and / or glaucoma. Damaged or unhealthy axons are eliminated through an intrinsic self-destruction program, which is different from traditional cell death pathways, such as apoptosis known as Wallerian degeneration. (Gerdts, J. et al., Neuron, 2016, 89, 449-460; Whitmore, AV et al., Cell Death Differ., 2003, 10, 260-261). In Wallerian degeneration, peripheral nerves selectively decompose at the distal axon segment of the injury, while the proximal axon segment and cell body remain intact. This degeneration is characterized by the initial depletion of nicotinamide mononucleotide adenylyltransferase (NMNAT), followed by nicotinamide adenine dinucleotide (NAD+) depletion, adenosine triphosphate (ATP) depletion, neurofilament proteolysis, and finally axonal degeneration approximately 8 to 24 hours after injury (Gerdts, J. et al., Neuron, 2016, 89, 449-460).

[0081] NAD+ is a ubiquitous metabolite that plays a key role in energy metabolism and cell signaling (Belenkey et al., Trends Biochem., 2007, 32, 12-19; ​​Chiarugi et al., Nat. Rev. Cancer, 2012, 12, 741-752). Homeostatic regulation of NAD+ levels is also responsible for maintaining axonal stability and integrity. Therefore, manipulations that increase the axonal localization of NMNAT1 confer axonal protection (Babetto et al., Cell Rep., 2010, 3, 1422-1429; Sasaki et al., J. Neurosci., 2009).

[0082] In a genome-wide RNAi screen of primary mouse neurons, SARM1 (Sterile Alpha and TIR motif-containing 1) was identified, where knockdown of SARM1 confers long-lasting protection against injury-induced axonal degeneration in sensory neurons (Gerdts et al., J Neurosci, 2013, 33, 13569-13580). SAR belongs to the cytoplasmic adaptor protein family, but is unique in this family because it is the evolutionarily oldest adaptor, paradoxically inhibits TLR signaling, and has been identified as a core executioner of the injury-induced axon death pathway (O'Neill, LA and Bowie, AG, Nat. Rev. Immunol., 2007, 7, 353-364; Osterloh, JM et al., Science, 2012, 337, 481-484; Gerdts, J. et al., Journal of Neuroscience 33, 2013, 13569-13580). Activation of SARM1 by axonal injury or forced dimerization of the SARM1-TIR domain promotes rapid and catastrophic depletion of nicotinamide adenine dinucleotide (NAD+), which is quickly followed by axonal degeneration, highlighting the central role of NAD+ homeostasis in axonal integrity. (Gerdts, J. et al., Science, 2015, 348, 453-457). SARM1 is essential for this injury-induced NAD+ depletion both in vivo and in vitro, and activation of SARM1 triggers axonal degeneration locally via NAD(+) disruption (Gerdts et al., Science, 2015, 348, 452-457; Sasaki et al., J. Biol. Chem. 2015, 290, 17228-17238; both are hereby incorporated by reference in their entirety).

[0083] Genetic loss of function studies have shown that SARM1 acts as a core executor of the axonal degeneration pathway after injury. Genetic knockout of SARM1 can preserve axons after nerve transection for up to 14 days (Osterloh, JM et al., Science, 2012, 337, 481-484; Gerdts, J. et al., Journal of Neuroscience, 2013, 33, 13569-13580), and improve functional outcomes after traumatic brain injury in mice (Henninger, N. et al., Brain 139, 2016, 1094-1105). In addition to the direct role of SARM1 in axonal injury, axonal degeneration observed in chemotherapy-induced peripheral neuropathy (CIPN) also requires SARM1. Loss of SARM1 blocks CIPN, which inhibits both axonal degeneration and increased pain sensitivity following treatment with the chemotherapy vincristine (Geisler et al., Brain, 2016, 139, 3092-3108).

[0084] SARM1 contains multiple conserved motifs, including the SAM domain, ARM / HEAT motif, and TIR domain ( Figure 1 ), these motifs mediate oligomerization and protein-protein interactions (O'Neill, LA and Bowie, AG, Nature Reviews Immunology, 2007, 7, 353-364; Tewari, R. et al., Trends Cell Biol., 2010, 20, 470-481; Qiao, F. and Bowie, JU, Sci. STKE 2005, re7, 2005). TIR domains are commonly found in signaling proteins that function in innate immune pathways, where they serve as scaffolds for protein complexes (O'Neill, LA and Bowie, AG, Nature Reviews Immunology, 2007, 7, 353-364). Interestingly, dimerization of the SARM1-TIR domain is sufficient to induce axonal degeneration and rapidly triggers the degradation of NAD+ by acting as an NAD+ lyase (Milbrandt et al., WO 2018 / 057989; Gerdts, J. et al., Science, 2015, 348, 453-457). Given the central role of SARM1 in the axonal degeneration pathway and its established NAD enzyme activity, much effort has been made to identify agents that can modulate SARM1 and may serve as useful therapeutic agents, for example, to prevent the occurrence of neurodegenerative diseases, including peripheral neuropathy, traumatic brain injury and / or neurodegenerative diseases.

The specific effective dosage level for any particular patient or organism will vary from subject to subject, depending on a variety of factors, including the condition being treated and the severity of the condition; the activity of the specific compound employed; the specific composition employed and its route of administration; the species, age, weight, sex, and diet of the patient; the general condition of the subject; the time of administration; the excretion rate of the specific compound employed; the duration of treatment; drugs used in combination or concomitantly with the specific compound employed, and the like.

[0393] The compositions provided can be administered orally, parenterally, by inhalation or nasal spray, topically (e.g., by powder, ointment, or drops), rectally, buccally, vaginally, intraperitoneally, intracisternalally, or via an implanted reservoir, depending on the severity of the condition being treated. Preferably, the compositions are administered orally, intraperitoneally, or intravenously. In certain embodiments, the compounds provided are administered orally or parenterally at a dosage level of about 0.01 mg / kg to about 50 mg / kg of subject body weight, once or more per day, to achieve the desired therapeutic effect.

[0394] The term "parenteral" as used herein includes subcutaneous, intravenous, intramuscular, intraarticular, intrasynovial, intrasternal, intrathecal, intrahepatic, intralesional and intracranial injection or infusion techniques. The sterile injectable form of the composition provided can be an aqueous or oily suspension. These suspensions can be formulated using suitable dispersants or wetting agents and suspending agents according to techniques known in the art. Sterile injectable preparations can also be sterile injectable solutions or suspensions in nontoxic parenteral acceptable diluents or solvents, for example, as a solution in 1,3-butanediol. Acceptable vehicles and solvents that can be used are water, Ringer's solution and isotonic sodium chloride solution. In addition, sterile fixed oils are conventionally used as solvents or suspending media.

[0395] For this purpose, any mild fixed oil can be used, including synthetic mono- or diglycerides. Fatty acids, such as oleic acid and its glyceride derivatives can be used to prepare injectables, as can natural pharmaceutically acceptable oils, such as olive oil or castor oil, particularly their polyoxyethylated forms. These oil solutions or suspensions can also contain long-chain alcohol diluents or dispersants, such as carboxymethyl cellulose or similar dispersants, which are commonly used in the preparation of pharmaceutically acceptable dosage forms, including emulsions and suspensions. Other commonly used surfactants, such as Tweens, Spans and other emulsifiers or bioavailability enhancers, which are commonly used in the manufacture of pharmaceutically acceptable solids, liquids or other dosage forms, can also be used for formulation purposes.

[0396] The injectable formulations can be sterilized, for example, by filtration through a bacteria-retaining filter, or by incorporating sterilizing agents in the form of sterile solid compositions that can be dissolved or dispersed in sterile water or other sterile injectable medium prior to use.

[0397] In order to prolong the effect of the provided compound, it is generally desirable to slow down the absorption of the compound injected subcutaneously or intramuscularly. This can be achieved by using a liquid suspension of a crystalline or amorphous material with poor water solubility. The absorption rate of the compound then depends on its solubility, which in turn can depend on the crystal size and crystalline form. Alternatively, delayed absorption of the compound form administered parenterally can be achieved by dissolving or suspending the compound in an oily vehicle. Injectable depot forms are made by forming a microcapsule matrix of the compound in a biodegradable polymer such as polylactide-polyglycolide. Depending on the ratio of the compound to the polymer and the properties of the specific polymer used, the release rate of the compound can be controlled. Examples of other biodegradable polymers include poly(orthoesters) and poly(anhydrides). Depot injectable formulations can also be prepared by encapsulating the compound in liposomes or microemulsions compatible with body tissues.

[0398] The pharmaceutically acceptable compositions described herein can be orally administered in any orally acceptable dosage form, including but not limited to capsules, tablets, aqueous suspensions, or solutions. In such solid dosage forms, the active compound can be mixed with at least one inert diluent such as sucrose, lactose, or starch. Such dosage forms may also contain additional substances other than the inert diluent, such as lubricants and other tableting aids, such as magnesium stearate and microcrystalline cellulose, as is normal practice.

In addition to inert diluents, oral compositions may also include adjuvants, such as wetting agents, emulsifiers and suspending agents, sweeteners, flavorings, and aromatics.

[0402] Alternatively, the pharmaceutically acceptable compositions described herein can be administered in the form of suppositories for rectal or vaginal administration. These can be prepared by mixing the compounds of the present disclosure with suitable non-irritating excipients or carriers that are solid at room temperature but liquid at body temperature (e.g., rectal or vaginal temperature) and therefore will melt in the rectum or vaginal cavity to release the active compound. Such materials include cocoa butter, suppository waxes (e.g., beeswax), and polyethylene glycol.

[0403] The pharmaceutically acceptable compositions described herein may also be administered topically, particularly when the target of treatment includes areas or organs readily accessible by topical application, including diseases of the eye, skin, or lower intestinal tract.

Such neuropathy can include peripheral neuropathy, central neuropathy and combinations thereof. In addition, peripheral neurological manifestations can be mainly produced by diseases concentrated in the central nervous system, and central nervous system manifestations can be produced substantially by peripheral or systemic diseases.

[0457] In some embodiments, peripheral neuropathy can be related to the damage to peripheral nerves, and / or can be caused by nerve diseases or due to systemic diseases.Some such diseases can include diabetes, uremia, infectious diseases such as AID or leprosy, nutritional deficiencies, blood vessels or collagen disorders such as atherosclerosis, and autoimmune diseases such as systemic lupus erythematosus, scleroderma, sarcoidosis, rheumatoid arthritis and polyarteritis nodosa.In some embodiments, peripheral nerve degeneration is caused by traumatic (mechanical) damage to nerves and chemical or thermal damage to nerves. Such conditions that damage peripheral nerves include compression or pinching, such as glaucoma, carpal tunnel syndrome, direct trauma, penetrating trauma, contusion, fracture or bone dislocation; Pressure related to superficial nerves (ulnar, radial or peroneal nerves), which may be due to long-term use of crutches or staying too long in one position, or due to tumors; Intraneural hemorrhage; Local ischemia; Exposure to cold or radiation or certain drugs or toxic substances, such as herbicides or pesticides. In particular, nerve damage may be due to chemical damage from cytotoxic anticancer agents, such as paclitaxel, cisplatin, proteasome inhibitors, or vinca alkaloids, such as vincristine. Typical symptoms of this type of peripheral neuropathy include weakness, numbness, paresthesia (abnormal sensations such as burning, itching, tingling, or numbness) and pain in the arms, hands, legs, and / or feet. In some embodiments, neuropathy is associated with mitochondrial dysfunction. This neuropathy can manifest as a decrease in energy levels, i.e., a decrease in NAD and ATP levels.

[0458] In some embodiments, peripheral neuropathy is a metabolic and endocrine neuropathy, which includes a wide range of peripheral nerve disorders associated with systemic diseases of metabolic origin. These diseases include, for example, diabetes, hypoglycemia, uremia, hypothyroidism, liver failure, polycythemia, amyloidosis, acromegaly, porphyria, lipid / glycolipid metabolism disorders, nutritional / vitamin deficiencies, and mitochondrial disorders. The common feature of these diseases is that the structure or function of myelin and axons is altered due to metabolic pathway imbalance, resulting in involvement of peripheral nerves.

[0459] In some embodiments, the neuropathy includes optic neuropathy, such as glaucoma; retinal ganglion degeneration, such as retinal ganglion degeneration associated with retinitis pigmentosa and outer retinal neuropathy; optic nerve neuritis and / or degeneration, including optic neuritis and / or degeneration associated with multiple sclerosis; traumatic injury to the optic nerve, which may include, for example, injury during tumor resection; hereditary optic neuropathies, such as Kjer's disease and Leber's hereditary optic neuropathy; ischemic optic neuropathy, such as optic neuropathy secondary to giant cell arteritis; metabolic optic neuropathy, such as neurodegenerative diseases, including the aforementioned Leber's neuropathy, nutritional deficiencies, such as vitamin B12 or folic acid deficiency, and poisoning, such as due to ethambutol or cyanide; neuropathy caused by adverse drug reactions and neuropathy caused by vitamin deficiency. Ischemic optic neuropathy also includes non-arteritic anterior ischemic optic neuropathy.

[0460] In some embodiments, the neurodegenerative diseases associated with neuropathy or axonopathy in the central nervous system include a variety of diseases. Such diseases include diseases involving progressive dementia, such as Alzheimer's disease, senile dementia, Pick's disease (Pick's disease) and Huntington's disease; central nervous system diseases that affect muscle function, such as Parkinson's disease, motor neuron disease and progressive ataxia, such as amyotrophic lateral sclerosis; demyelinating diseases, such as multiple sclerosis; viral encephalitis, such as viral encephalitis caused by enterovirus, arbovirus and herpes simplex virus; and prion disease. Mechanical injury, such as glaucoma or traumatic injury to the head and spine, can also cause nerve damage and degeneration of the brain and spinal cord. In addition, ischemia and stroke and conditions such as nutritional deficiencies and chemical toxicity (such as chemotherapeutic agents) can also cause central nervous system neuropathy.

[0461] In some embodiments, the present disclosure provides a method for treating a neuropathy or axonopathy associated with axonal degeneration. In some such embodiments, the neuropathy or axonopathy associated with axonal degeneration can be any of a variety of neuropathy or axonopathy, such as those that are hereditary or congenital or are associated with Parkinson's disease, Alzheimer's disease, herpes infection, diabetes, amyotrophic lateral sclerosis, demyelinating disease, ischemia or stroke, chemical injury, thermal injury, and AIDS. In addition, neurodegenerative diseases not mentioned above and subsets of the diseases mentioned above can also be treated with the methods of the present disclosure. Such disease subsets can include Parkinson's disease or non-Parkinson's disease, or Alzheimer's disease.

[0488] Example 1: SAM-TIR SARM1 IC50 determination

[0489] This example describes an assay for SAM-TIR NADase activity and its use to measure the efficacy of compounds of Formula I in blocking SARM1-mediated NAD+ cleavage. This assay has been optimized to characterize the efficacy of compounds of Formula I in inhibiting SARM1 activity and to calculate IC50 values ​​for each compound. The assay utilizes a fragment of the SARM1 molecule containing both the SAM and TIR domains. As demonstrated herein, expression of this fragment without the autoinhibitory N-terminal domain results in a constitutively active enzyme that cleaves NAD+.

[0490] Preparation of SARM1 SAM-TIR Lysate (STL)

[0491] NRK1-HEK293T cells are a cell line stably transfected with an FCIV expression vector expressing human nicotinamide riboside kinase 1 (NRK1), an enzyme that converts the NAD+ biosynthetic precursor nicotinamide riboside (NR) into NMN, the direct precursor of NAD+. When provided with NR, this cell line, while expressing the SARM1 SAM-TIR, increases intracellular NAD+ levels and maintains cell viability. Figure 2 The NRK1-HEK293T stable line with NR supplementation maintains higher NAD+ levels after SARM1-TIR expression. Data were generated from three independent NAD+ measurements from three independent transfection experiments and normalized to data from a non-transfection experiment run simultaneously. Data are presented as mean ± SEM; error bars: SEM; ***P < 0.001 two-tailed Student's t-test.

[0492] NRK1-HEK293T cells represent a cell line stably transfected with an FCIV expression vector that expresses human nicotinamide riboside kinase 1 (NRK1), an enzyme that converts the NAD+ biosynthetic precursor nicotinamide riboside (NR) into NMN, the direct precursor of NAD+.

[0493] NRK1-HEK293T cells were seeded at 20 × 106 cells per plate in 150 cm 2 The next day, use X-TREMEGENE TM The cells were transfected with 15 μg of FCIV-SST (SAM-TIR expression plasmid, SEQ ID NO: 1) using 9DNA transfection reagent (Roche product #06365787001).

[0494]

[0495] During transfection, the culture medium was supplemented with 1 mM NR to minimize the toxicity of SAM-TIR overexpression. Forty-eight hours after transfection, cells were harvested, pelleted by centrifugation at 1,000 rpm (Sorvall ST 16R centrifuge, Thermo Fisher), and washed once with cold PBS (0.01 M phosphate-buffered saline; NaCl 0.138 M; KCl 0.0027 M; pH 7.4). Cells were resuspended in PBS with protease inhibitors (cOmplete). TM Cell lysates were prepared by sonication (Branson Sonifer 450, output = 3, 20 strokes) in PBS containing a protease inhibitor cocktail (Roche product #11873580001). Lysates were centrifuged (12,000 × g, 10 minutes at 4°C) to remove cell debris, and the supernatant (containing SARM1 SAM-TIR protein) was stored at -80°C for subsequent use in an in vitro SARM1 SAM-TIR NADase assay (see below). Protein concentration was determined using the bicinchoninic acid (BCA) method and used to normalize lysate concentrations.

[0496] SAM-TIR of the compound shown in Formula I IC50 determination

[0497] The enzymatic assay was performed in 384-well polypropylene plates in Dulbecco's PBS buffer with a final assay volume of 20 μL. SAM-TIR lysates at a final concentration of 5 μg / mL were pre-incubated with the corresponding compound at a final assay concentration of 1% DMSO at room temperature for 2 hours. The reaction was initiated by adding NAD+ at a final assay concentration of 5 μM as a substrate. After incubation at room temperature for 2 hours, the reaction was terminated with 40 μL of 7.5% trichloroacetic acid in acetonitrile. The concentrations of NAD+ and ADPR were analyzed using an API4000 triple quadrupole mass spectrometer (ABSciex Framingham, MA) using a RapidFire high-throughput mass spectrometry system (Agilent Technologies, Santa Clara, CA).

[0498] The results are listed in Table 1 below. IC values ​​of compounds with activity designated as "A" 50 <5 μM; IC for compounds with activity designated as "B" 50 The IC values ​​for compounds designated as "C" were 5-15 μM. 50 The IC values ​​of compounds designated as "D" were 15.01-30 μM. 50 >30μM.

[0502] Example 2: Axonal Degeneration Index

[0503] This example illustrates an in vitro axonal degeneration assay used to characterize compounds of Formula I. This assay was used to test the efficacy of compounds of Formula I in preventing axonal degeneration in mouse dorsal root ganglion (DRG) hanging drop cultures.

[0504] Mouse DRG hanging drop culture

[0505] Mouse dorsal root ganglion neurons (DRGs) were dissected from E12.5 CD1 mice (50 ganglia per embryo) and incubated with 0.5% trypsin solution containing 0.02% EDTA (Gibco) at 37°C for 15 minutes. The cells were then triturated by gentle pipetting and washed three times with DRG growth medium (Neurobasal medium (Gibco) containing 2% B27 (Invitrogen), 100 ng / ml 2.5S NGF (Harland Bioproducts), 1 mM 5-fluoro-2'-deoxyuridine (Sigma), penicillin, and streptomycin). The cells were suspended in DRG growth medium. 5000 cells / well were spotted into the center of each well of a 96-well tissue culture plate coated with poly-D-lysine (0.1 mg / ml; Sigma) and laminin (3 mg / ml; Invitrogen) to create DRG hanging drop cultures. The cells were allowed to adhere to the plates in a humidified tissue culture incubator (5% CO2) for 15 minutes, after which DRG growth medium (100 ml per well) was gently added.

[0506] Axonal degeneration assay

[0507] Axonal degeneration was stimulated by manual axonal transection using a scalpel or by chemical toxic stimulation. After the appropriate experimental time period, DRG cultures were fixed in 1% PFA plus sucrose and stored in the refrigerator before imaging. Brightfield images of DRG axons and cell bodies were collected using a 20x water immersion lens on a Phenix automated confocal microscope (PerkinElmer), and axon quantification was performed using an in-house developed script (Acapella, PerkinElmer).

[0508] The results are listed in Table 2 below. The compounds described herein demonstrated protection against axonal disruption in cellular assays and were evaluated by IC 50Sorting was performed at 10-30μM (B) and <10μM (A).
