BACKGROUND

Neurodegenerative diseases are increasingly recognized as major causes of death and disability (including disability-adjusted life-years (DALYs; the sum of years of life lost [YLLs] and years lived with disability [YLDs]) worldwide. Globally, in 2016, neurological disorders were the leading cause of DALYs (˜276 million) and second leading cause of deaths (˜9.0 million). See Global Burden of Diseases, Injuries, and Risk Factors Study (GBD). Lancet Neurol 2019; 18:459-80.


Neurodegenerative disorders can be broadly classified by their clinical presentations, with extrapyramidal and pyramidal movement disorders and cognitive or behavioral disorders being the most common. Few patients have pure syndromes, with most having mixed clinical features. Although neurodegenerative diseases are typically defined by specific protein accumulations and anatomic vulnerability, neurodegenerative diseases share many fundamental processes associated with progressive neuronal dysfunction and death, such as proteotoxic stress and its attendant abnormalities in ubiquitin—proteasomal and autophagosomal/lysosomal systems, oxidative stress, programmed cell death, and neuroinflammation. See Dugger B N and Dickson D W. Cold Spring Harb Perspect Biol. 2017. 9 (7): a028035.


Parkinson's disease (PD) is a progressive neurodegenerative disorder characterized by a progressive loss of nigral dopaminergic neurons. The dominant presence of α-synuclein (α-syn) aggregates in intracellular inclusions, inside and outside the central nervous system (CNS), is a disease driver providing a signature for systemic disease with multiorgan involvement and consequent immune responses. Linkages between innate (monocytes and microglia) and adaptive (T cells) immunity, inflammation and disease are well established. The principal drivers are α-syn misfolding and aggregation, impairment of protein clearance, mitochondrial dysfunction, and inflammation. All of these affect dopaminergic neuronal function with secondary effects on noradrenergic, glutamatergic, serotonergic, and adenosine neuronal vitality. The disease is highlighted by the release of α-syn aggregates into the systemic circulation breaking the immune tolerance. In particular, activated monocytes enter the meninges and choroid plexus and provide early deleterious effects on neuroimmune homeostasis. Based on these findings, efforts to maintain immune homeostasis are attractive targets for PD-modifying therapies. One means to restore immune homeostasis, inside and outside the CNS, has focused on the immune transformation. Notably, a balanced transformation of monocytes-macrophages, effector T cells (Teff) to regulatory T cells (Treg), and the interactions between the two are of putative clinical benefit for PD as well as for Alzheimer's disease (AD), traumatic brain injury, stroke, and amyotrophic lateral sclerosis (ALS). The enhancement of Treg numbers and function leads to restoration of innate microglial homeostasis and control of neuroinflammation and neuroprotection. See Schabitz W R, et al.

J Neurol Neurosurg Psychiatry. 2020. 91, 795-808.


The increasing recognition that inflammation can play a critical role in neurodegenerative diseases of the CNS is highlighted by both adaptive versus innate immune responses being observed at various stages of neurodegenerative diseases. These differential immune responses may not only drive disease processes but could serve as therapeutic targets. Ongoing investigations into the specific inflammatory mechanisms that play roles in disease causation and progression have revealed lessons about inflammation-driven neurodegeneration understanding the advent of these diseases, as well as therapeutics to treat them. An increasing number of immunotherapeutic strategies that have been successful in MS are now being applied to other neurodegenerative diseases. Some approaches suppress CNS immune mechanisms, while others harness the immune system to clear deleterious products and cells. See Mamun A A and Liu F. Neurol Neurother. 2017. 2 (1); Chitnas T and Weiner H L. J Clin Invest. 2017. 127 (10): 3577-3587.


It is critical to note that not all immune responses in the CNS are detrimental, and in many cases, they actually aid repair and regeneration. For example, microglia clear debris after myelin damage and when this is impeded, delayed regeneration occurs. Immune activation is also crucial to limit neurotropic viral infections and removes necrotic cells following ischemia. Thus, microglia can exert dual roles in neurodegeneration, both as instigators of damage and as guardians of brain homeostasis. Besides microglia, T cells can also aid recovery during neurodegenerative diseases, although the exact mechanisms for this beneficial role of T cells are not clear. Detailed studies of neuroimmune interaction at both cellular and molecular levels have revealed complex interactions, demonstrating that immune cells can secrete both neurotoxic and neuroprotective molecules. As such, regulation of the immune response in neurological disorders has therapeutic value. See Neumann H et al. Brain. 2009. 132:288-95; Schwartz M et al. Neuroscience. 2009. 158:1133-42; Amor S et al. Immunology. 2010. 129 (2): 154-69.


The clinical and pathobiological diversity of Parkinson's disease has presented as a major challenge in the development of relevant biomarkers to monitor disease progression and disease-modifying therapies. Further, since therapeutic response can vary based on heterogeneous clinical and molecular phenotypes, a shift toward personalized or precision medicine approaches, including biomarker development and validation, has been thought to improve the management of many neurodegenerative diseases like PD.


Granulocyte Macrophage—Colony Stimulating Factor (GM-CSF) is a hematological growth factor that regulates the production, migration, proliferation, differentiation and function of hematopoietic cells. It was first identified as being able to induce, in vitro, the proliferation and differentiation of bone marrow progenitors into granulocytes and macrophages. In response to inflammatory stimuli, GM-CSF is released by various cell types including T lymphocytes, macrophages, fibroblasts and endothelial cells. GM-CSF then activates and enhances the production and survival of neutrophils, eosinophils, and macrophages. Native GM-CSF is usually produced near the site of action where it modulates in vitro proliferation, differentiation, and survival of hematopoietic progenitor cells, but is present in circulating blood in only picomolar concentrations (10−10 to 10−12 M). Several studies have shown that GM-CSF has a wide range of functions across different tissues in its action on myeloid cells, and GM-CSF deletion/depletion approaches have indicated its potential as an important therapeutic target in several inflammatory and autoimmune disorders. See A Metcalf D. Immunol Cell Biology. 1987, 65:35-43; Gasson J C. Blood. 1991, 77:1131-1145; Shannon M F et al. Crit Rev Immunol. 1997, 17:301-323; Alexander W S. Int Rev Immunol. 1998, 16:651-682; Barreda D R et al. Dev Comp Immunol. 2004, 28:509-554; Lee K M C et al. Immunotargets Ther. 2020. 9:225-240.


Recombinant human granulocyte-macrophage colony-stimulating factor (rhu GM-CSF) has been approved by the FDA for the treatment of neutropenia, blood dyscrasias and malignancies like leukemia in combination with chemotherapies. In the clinic, GM-CSF used for treatment of neutropenia and aplastic anemia following chemotherapy greatly reduces the risk of infection associated with bone marrow transplantation. Its utility in myeloid leukemia treatment and as a vaccine adjuvant is also well established. See Dorr R T. Clin Therapeutics. 1993. 15 (1): 19-29; Armitage J O. Blood 1998, 92:4491-4508; Kovacic J C et al. J Mol Cell Cardiol. 2007, 42:19-33; Jacobs P P et al. Microbial Cell Factories 2010, 9:93.


The identification of specific biomarkers can be used for the diagnosis, prognosis, or theranosis of neurodegenerative diseases like Parkinson's disease. There remains a need for new and more effective biomarkers and combination treatments of Parkinson's disease.

Compositions

In embodiments, the present disclosure pertains to pharmaceutical compositions comprising the compositions, e.g. GM-CSF and/or an additional therapeutics to treat a Parkinson's disease.


In embodiments, the additional neurological agent and/or additional therapeutic agent is selected from selected from dopamine precursors such as levodopa, carbidopa (LODOSYN), dopamine agonists such as selegiline (ZELAPAR), MAO B inhibitors such as selegiline (ZELAPAR), catechol o-methyltransferase (COMT) inhibitors such as entacapone (COMTAN), anticholinergics such as benztropine (COGENTIN), amantadine, adenosine receptor antagonists (A2A receptor antagonists) such as istradefylline (NOURIANZ), and/or pimavanserin (NUPLAZID).


In embodiments, the neurological agent and/or additional therapeutic agent to treat Parkinson's disease is an antibody or antibody format which is selected from one or more of a monoclonal antibody, polyclonal antibody, antibody fragment, Fab, Fab′, Fab′-SH, F(ab′)2, Fv, single chain Fv, diabody, linear antibody, bispecific antibody, multispecific antibody, chimeric antibody, humanized antibody, human antibody, and fusion protein comprising the antigen-binding portion of an antibody.


Compositions of GM-CSF

GM-CSF, in embodiments, includes any pharmaceutically safe and effective GM-CSF, or any derivative thereof having the biological activity of GM-CSF. In embodiments, the GM-CSF is rhu GM-CSF, such as sargramostim (LEUKINE). Sargramostim is a biosynthetic, yeast-derived, recombinant human GM-CSF, having a single 127 amino acid glycoprotein that differs from endogenous human GM-CSF by having a leucine instead of a proline at position 23. Other natural and synthetic GM-CSFs, and derivatives thereof having the biological activity of natural human GM-CSF, may be equally useful in embodiments.


In embodiments, the GM-CSF is produced or producible in bacteria, yeasts, plants, insect cells, and mammalian cells. In embodiments, the GM-CSF is produced or producible in Escherichia coli cells. In embodiments, the GM-CSF is produced or producible in yeast cells. In embodiments, the GM-CSF is produced or producible in Chinese hamster ovary cells (CHO). In embodiments, the GM-CSF is not produced in E. coli cells. In embodiments, the GM-CSF is produced in a cell that allows for glycosylation, e.g. yeast or CHO cells.


In embodiments, the GM-CSF has an amino acid sequence of SEQ ID NO: 1, or a variant of at least about 90%, or at least about 93%, or at least about 95%, or at least about 97%, or at least about 98% identity thereto. In embodiments, the GM-CSF has an amino acid sequence of SEQ ID NO: 2, SEQ ID NO: 3, and SEQ ID NO: 4, or a variant of at least about 90%, or at least about 93%, or at least about 95%, or at least about 97%, or at least about 98% identity thereto. In embodiments, the GM-CSF is one of, sargramostim, molgramostim, and regramostim. In embodiments, the GM-CSF is sargramostim.


Without wishing to be bound by theory, the core of hGM-CSF consists of four helices that pack at angles. Crystal structures and mutagenic analysis of rhGM-CSF (Rozwarski D A et al., Proteins 26:304-13, 1996) showed that, in addition to apolar side chains in the protein core, 10 buried hydrogen bonding residues involve intramolecular hydrogen bonding to main chain atoms that were better conserved than residues hydrogen bonding to other side chain atoms; 24 solvation sites were observed at equivalent positions in the two molecules in the asymmetric unit, and the strongest among these was located in clefts between secondary structural elements. Two surface clusters of hydrophobic side chains are located near the expected receptor binding regions. Mutagenesis of residues on the helix A/helix C face confirmed the importance of certain Glu, Gly, and Gln residues. These residues are therefore not to be substituted in the functional substitution variants of hGM-CSF for use in the present disclosure and these helices are to be retained in a functional fragments or deletion variants of hGM-CSF for use in this disclosure. Further, in embodiments, one of ordinary skill can reference UniProtKB entry P04141 for structure information to inform the identity of variants.


The N-terminal helix of hGM-CSF governs high affinity binding to its receptor (Shanafelt A B et al., EMBO J 10:4105-12, 1991) Transduction of the biological effects of GM-CSF requires interaction with at least two cell surface receptor components, (one of which is shared with the cytokine IL-5). The above study identified receptor binding determinants in GM-CSF by locating unique receptor binding domains on a series of human-mouse hybrid GM-CSF cytokines. The interaction of GM-CSF with the shared subunit of their high affinity receptor complexes was governed by a very small part of the peptide chains. The presence of a few key residues in the N-terminal α-helix of was sufficient to confer specificity to the interaction.


In embodiments, the amino acid mutations are amino acid substitutions, and may include conservative and/or non-conservative substitutions.


“Conservative substitutions” may be made, for instance, based on similarity in polarity, charge, size, solubility, hydrophobicity, hydrophilicity, and/or the amphipathic nature of the amino acid residues involved. The 20 naturally occurring amino acids can be grouped into the following six standard amino acid groups: (1) hydrophobic: Met, Ala, Val, Leu, Ile; (2) neutral hydrophilic: Cys, Ser, Thr; Asn, Gln; (3) acidic: Asp, Glu; (4) basic: His, Lys, Arg; (5) residues that influence chain orientation: Gly, Pro; and (6) aromatic: Trp, Tyr, Phe.


As used herein, “conservative substitutions” are defined as exchanges of an amino acid by another amino acid listed within the same group of the six standard amino acid groups shown above. For example, the exchange of Asp by Glu retains one negative charge in the so modified polypeptide. In addition, glycine and proline may be substituted for one another based on their ability to disrupt α-helices.


As used herein, “non-conservative substitutions” are defined as exchanges of an amino acid by another amino acid listed in a different group of the six standard amino acid groups (1) to (6) shown above.


In embodiments, the substitutions may also include non-classical amino acids (e.g. selenocysteine, pyrrolysine, N-formylmethionine β-alanine, GABA and δ-Aminolevulinic acid, 4-aminobenzoic acid (PABA), D-isomers of the common amino acids, 2,4-diaminobutyric acid, α-amino isobutyric acid, 4-aminobutyric acid, Abu, 2-amino butyric acid, γ-Abu, ε-Ahx, 6-amino hexanoic acid, Aib, 2-amino isobutyric acid, 3-amino propionic acid, ornithine, norleucine, norvaline, hydroxyproline, sarcosme, citrulline, homocitrulline, cysteic t-butylglycine, acid, t-butylalanine, phenylglycine, cyclohexylalanine, β-alanine, fluoro-amino acids, designer amino acids such as β methyl amino acids, C α-methyl amino acids, N α-methyl amino acids, and amino acid analogs in general).


Modification of the amino acid sequences may be achieved using any known technique in the art e.g., site-directed mutagenesis or PCR based mutagenesis. Such techniques are described, for example, in Sambrook et al., Molecular Cloning: A Laboratory Manual, Cold Spring Harbor Press, Plainview, N.Y., 1989 and Ausubel et al., Current Protocols in Molecular Biology, John Wiley & Sons, New York, N.Y., 1989. Without wishing to be bound by theory, the degree of glycosylation of biosynthetic GM-CSFs appears to influence half-life, distribution, and elimination. (Lieschke and Burgess, N. Engl. J. Med. 327:28-35, 1992; Dorr, R. T., Clin. Ther. 15:19-29, 1993; Horgaard et al., Eur. J. Hematol. 50:32-36, 1993). In embodiments, the present GM-CSF molecules are glycosylated.

Suitable controlled- or sustained-release formulations known to those skilled in the art, including those described herein, can be readily selected for use with the active ingredients of the agents described herein. The disclosure thus provides single unit dosage forms suitable for oral administration such as, but not limited to, tablets, capsules, gelcaps, and caplets that are adapted for controlled- or sustained-release.


Controlled- or sustained-release of an active ingredient can be stimulated by various conditions, including but not limited to, changes in pH, changes in temperature, stimulation by an appropriate wavelength of light, concentration or availability of enzymes, concentration or availability of water, or other physiological conditions or compounds.


In another embodiment, a controlled-release system can be placed in proximity of the target area to be treated, thus requiring only a fraction of the systemic dose (see, e.g., Goodson, in Medical Applications of Controlled Release, supra, vol. 2, pp. 115-138 (1984)). Other controlled-release systems discussed in the review by Langer, 1990, Science 249:1527-1533) may be used.


Pharmaceutical formulations preferably are sterile. Sterilization can be accomplished, for example, by filtration through sterile filtration membranes. Where the composition is lyophilized, filter sterilization can be conducted prior to or following lyophilization and reconstitution.


Administration and Dosage

It will be appreciated that the actual dose of the composition to be administered according to the present disclosure will vary according to the particular dosage form, and the mode of administration. Many factors that may modify the action of the composition (e.g., body weight, gender, diet, time of administration, route of administration, rate of excretion, condition of the patient, drug combinations, genetic disposition and reaction sensitivities) can be taken into account by those skilled in the art. Administration can be carried out continuously or in one or more discrete doses within the maximum tolerated dose. Optimal administration rates for a given set of conditions can be ascertained by those skilled in the art using conventional dosage administration tests.


In embodiments, the GM-CSF is administered at a total dose of about 125 μg, about 150 μg, or about 200 μg, or about 250 μg, or about 300 μg, or about 350 μg. In embodiments, the GM-CSF is administered at a total dose of about 250 μg.


In embodiments, the GM-CSF is administered at a dose of about 125 μg, about 150 μg, or about 200 μg, or about 250 μg, or about 300 μg, or about 350 μg.


In embodiments, the GM-CSF is administered twice daily.


In embodiments, the GM-CSF is sargramostim, administered at a dose of about 125 μg, twice daily.


Combination Therapy and Additional Therapeutic Agents

In embodiments, the pharmaceutical composition of the present disclosure is co-administered in conjunction with additional agent(s), for example a neurological agent and/or additional therapeutic agent. Co-administration can be simultaneous or sequential.


In embodiments, the additional neurological agent and/or additional therapeutic agent and the GM-CSF of the present disclosure are administered to a patient simultaneously. The term “simultaneously” as used herein, means that the neurological agent and/or additional therapeutic agent and the GM-CSF are administered with a time separation of no more than about 60 minutes, such as no more than about 30 minutes, no more than about 20 minutes, no more than about 10 minutes, no more than about 5 minutes, or no more than about 1 minute. Administration of the neurological agent and/or additional therapeutic agent and the GM-CSF can be by simultaneous administration of a single formulation (e.g., a formulation comprising the additional therapeutic agent and the GM-CSF composition) or of separate formulations (e.g., a first formulation including the neurological agent and/or additional therapeutic agent and a second formulation including the GM-CSF composition).


Co-administration does not require the therapeutic agents to be administered simultaneously, if the timing of their administration is such that the pharmacological activities of the neurological agent and/or additional therapeutic agent and the GM-CSF overlap in time, thereby exerting a combined therapeutic effect. For example, the neurological agent and/or additional therapeutic agent and the targeting moiety, the GM-CSF composition can be administered sequentially. The term “sequentially” as used herein means that the neurological agent and/or additional therapeutic agent and the GM-CSF are administered with a time separation of more than about 60 minutes. For example, the time between the sequential administration of the neurological agent and/or additional therapeutic agent and the GM-CSF can be more than about 60 minutes, more than about 2 hours, more than about 5 hours, more than about 10 hours, more than about 1 day, more than about 2 days, more than about 3 days, more than about 1 week apart, more than about 2 weeks apart, or more than about one month apart. The optimal administration times will depend on the rates of metabolism, excretion, and/or the pharmacodynamic activity of the additional therapeutic agent and the GM-CSF being administered. Either the neurological agent and/or additional therapeutic agent or the GM-CSF composition may be administered first.


Co-administration also does not require the therapeutic agents to be administered to the patient by the same route of administration. Rather, each therapeutic agent can be administered by any appropriate route, for example, parenterally or non-parenterally.


In embodiments, the GM-CSF described herein acts synergistically when co-administered with the neurological agent and/or additional therapeutic agent. In such embodiments, the GM-CSF composition and the neurological agent and/or additional therapeutic agent may be administered at doses that are lower than the doses employed when the agents are used in the context of monotherapy.

EXAMPLES
Example 1: Monocyte Proteomic Profile after the Sargramostim Treatment

To obtain a detailed understanding of changes in the monocyte proteomic profile after the sargramostim treatment, functional and pathway enrichment analyses of differentially regulated proteins, at 2 and 6 months, after treatment were performed. At 2 months, multiple immune processes were enriched upon sargramostim treatment, including myeloid leukocyte mediated immunity (p=1.33E-08), myeloid cell activation involved in immune response (p=1.30E-07), and leukocyte activation involved in immune response (p=7.25E-06) (FIG. 1A). Similarly, Kyoto Encyclopedia of Genes and Genomes (KEGG) and Reactome analyses showed phagosome (p=2.74E-04) and innate immune system (p=1.29E-07) enrichments, respectively (FIG. 1A). In addition, there was an enrichment of inflammation processes including regulation of interleukin-8 (IL-8) (p=3.64E-02) and tumor necrosis factor (TNF) production pathways (p=1.73E-02) (FIG. 1A). Further, Ingenuity Pathway Analysis (IPA) showed inhibition of neuroinflammation signaling (p=1.43E-04), IL-8 (p=8.8E-04), integrin-linked kinase (ILK) (p=2.8E-02), nitric oxide and reactive oxygen species (ROS) (p=3.35E-02) pathways (FIG. 1A). Additionally, sargramostim affected endosomal (p=3.14E-02), Golgi vesicle (p=1.60E-03), endoplasmic reticulum to Golgi vesicle-mediated (p=1.02E-02), protein targeting to lysosome (p=2.78E-02), and regulation of late endosome to lysosome (p=3.88E-03) transport mechanisms (FIG. 1A). Further, cellular component and Reactome analyses showed enrichment of secretory vesicle (p=1.14E-13), endocytic vesicle (p=2.37E-05), transport vesicle (p=1.18E-03), phagocytic vesicle (p=5.16E-03), Golgi-associated vesicle (p=9.24E-03), lysosome (p=2.59E-09), and trans-Golgi network vesicle budding (p=4.19E-02) (FIG. 1A). Sargramostim treatment also induced changes in biological processes related to the RNA processing such as regulation of mRNA processing (p=2.16E-05) and regulation of RNA splicing (p=3.96E-04) (FIG. 1A). Similarly, KEGG and Reactome tests showed pathways affecting RNA processing (including RNA transport, p=3.70E-02), mRNA splicing (major and minor pathways, p=3.54E-05 and p=4.31E-02, respectively), and spliceosome (1.24E-03) (FIG. 1A).


Proteomic and scRNA-seq analyses at 6 months of sargramostim treatment also showed enrichment of immune processes, including monocyte-macrophage mediated immunity (p=6.03E-34), activation (p=2.29E-35), and innate immune responses (p=2.91E-27). Moreover, regulation of leukocyte activation (p=5.05E-03), lymphocyte chemotaxis (p=5.02E-03), and regulation of lymphocyte activation (p=6.540E-04) were shown (FIG. 2A). Similarly, proteomic Reactome analysis showed enrichment of innate immunity (p=3.66E-19) and phagosome formation (p=3.28E-02) (FIG. 2A and FIG. 2B). IPA of 6 month-scRNA-seq data sets showed chemokine signaling (p=1.84E-04), dendritic cell maturation (p=2.03E-04), and phagosome formation (p=3.73E-07) enrichments (FIG. 2A and FIG. 2B). In addition, there was an enrichment of regulation of ROS metabolism (p=3.22E-03), oxidative stress (p=7.07E-04), and oxygen containing compounds (p=1.16E-03) (FIG. 2A). These data indicated antioxidant effects that followed sargramostim treatment. Interestingly, IPA of 6 month-proteomic data showed inhibition of oxidative phosphorylation (p=1.36E-06). This suggested that control of ROS production can occur after sargramostim treatment (FIG. 2B). Moreover, 6 month-proteomic data showed an enrichment of mitochondria function (p=8.26E-40) as the organelle responsible for respiratory electron transport pathway (p=5.29E-15) enriched in Reactome analysis (FIG. 2A). Additionally, cellular component analysis of the both proteomic and scRNA-seq data sets showed enrichment of secretory (p=1.59E-38) and cytoplasmic (p=6.56E-03) vesicles (FIG. 2A). Six month-proteomic data sets demonstrated enrichment of autophagy (p=4.63E-04) and macroautophagy (1.51E-05) (biological process analysis) and activation of the sirtuin signaling pathway (IPA, p=2.19E-11) (FIG. 2A and FIG. 2B). The 6 month-scRNA-seq data also showed enrichment of pathways linked to regulation of inflammatory responses (p=5.87E-03), IL-10 negatively regulates plasma membrane-associated inflammatory mediators (p=9.67E-03), and receptor ACKR2 binds most inflammatory CC chemokines (p=3.16E-03) (FIG. 2A).


Example 2: Expression of Genes and Proteins Following Sargramostim Treatment

ddPCR and Western blotting were used to assess the expression of genes and proteins as biomarkers for predicting disease progression and therapeutic response following sargramostim treatment. The individual subject's baseline and treatment protein expression of LRRK2, HMOX1, TLR2, TLR8, RELA, ATG7, and GABARAPL2 at 2 and 6 months were compared after starting the sargramostim treatment. At 2 months, 4/5 of patients displayed significant decreased protein expression of LRRK2 and HMOX1, and 3/5 of patients displayed significant decreased expression of TLR2 protein following sargramostim initiation (FIG. 3A). In addition, 3/5 of patients showed decreased protein expression of TLR8 and NF-κB with significant downregulation in 1/3 of patients; subject 2005 for TLR8 and subject 2003 for NF-κB (FIG. 3A). Additionally, 1 patient displayed increased expression of ATG7 protein (subject 2003) and the same subject displayed significant increased expression of GABARAPL2 protein (FIG. 3A). At 6 months, 4/5 patients showed significant downregulation of LRRK2 and TLR2 (FIG. 3B). Notably, 5/5 of patients showed decreased protein expression of HMOX1. The downregulation was significant in 3/5 of patients (FIG. 3B). Similarly, 5/5 of patients showed decreased expression of NF-κB and the downregulation was significant in 4/5 of patients (FIG. 3B). In addition, downregulation of TLR8 protein was observed in 2/5 of patients (FIG. 3B). Only subject 2003 displayed limited increased expression of ATG7 protein while 3/5 of patients showed an upregulation of GABARAPL2 reaching near significance in 2/3 patients (subjects 2005 and 2006) (FIG. 3B). At the genetic level, the individual patient's baseline and treatment gene expression of LRRK2, HMOX1, TLR2, TLR8, RELA, ATG7, and GABARAPL2 at 2 and 6 months after initiating sargramostim were compared. At 2 months, 5/5 patients displayed significant decreased gene expression of LRRK2 and HMOX1, and 3/5 patients showed significant decreased expression of TLR2 and TLR8 genes after sargramostim treatment (FIG. 3C). Despite 4/5 patients having displayed significant decreased gene expression of NF-κB, the downregulation did not exceed 15% compared to the baseline (FIG. 3C). Interestingly, 4/5 patients showed significant upregulation of ATG7 gene, but the upregulation did not exceed 17%, compared to the baseline, in 2/4 subjects (subjects 2005 and 2006) (FIG. 3C). Similarly, 3/5 patients displayed significant upregulation of GABARAPL2 gene, but the upregulation did not exceed 17% compared to the baseline in the 3 subjects (FIG. 3C). At 6 months, 5/5 patients showed significant downregulation of HMOX1 and TLR2 genes (FIG. 3D). 3/5 and 4/5 patients showed significant downregulation of LRRK2 and TLR8 genes, respectively (FIG. 3D). Only 2/5 patients displayed significant decreased genetic expression of NF-κB with downregulation not exceeding 5% compared to the baseline (FIG. 3D). Interestingly, 4/5 patients showed significant upregulation of ATG7 gene (FIG. 3D). In accordance with 2 month-ddPCR data, 3/5 patients displayed significant increased gene expression of GABARAPL2, but the upregulation did not exceed 6%, compared to the baseline, in 2/3 subjects (subjects 2004 and 2005) (FIG. 3D).


Example 3: Integrated scRNA-Seq and Proteomic Data after Sargramostim Treatment

The overlapping genes between scRNA-seq and proteomic datasets of subjects 2003, 2004, and 2005 are illustrated using Venn diagram which show the number of genes identified in each dataset and the number of overlapped genes in both datasets (FIG. 4A). Pearson product-moment correlation coefficient between scRNA-seq and proteomic overlapping genes (r=0.3582, p=8.9627E-77) showed significant moderate positive association between the overlapping genes in both datasets (FIG. 4B). This indicates that the expression of multiple genes in both datasets has been changed in the same direction (downregulation or upregulation).


Example 4: Western Blot and ddPCR Correlations with Clinical MDS-UPDRS III Scores

Correlating the expression of potential biomarkers (at the gene or protein level) with MDS-UPDRS III scores of PD patients could be used to identify the potentiality of using clinical biomarkers to predict the disease progression and therapeutic response after immune modulator therapies such as sargramostim. Therefore, correlation analysis of the raw and change in MDS-UPDRS III score with the protein levels of selected biomarkers was performed. Positive correlations were shown between change in MDS-UPDRS III score and protein level of LRRK2 (r=0.3534, p=0.017), HMOX1 (r=0.0881, p=0.565), TLR8 (r=0.1531, p=0.315), and NF-κB (r=0.4258, p=0.004) (FIG. 5A), suggesting that motor function is improved with decreased expression of any of these proteins. In addition, negative correlations were shown between change in MDS-UPDRS III score and protein level of ATG7 (r=−0.2440, p=0.106) and GABARAPL2 (r=−0.1376, p=0.367) (FIG. 5A), Similarly, positive correlations were shown between raw MDS-UPDRS III score and protein level of LRRK2 (r=0.2659, p=0.077), HMOX1 (r=0.1109, p=0.468), TLR2 (r=0.3704, p=0.012), and NF-κB (r=0.1847, p=0.224) (FIG. 5B), while negative correlations were shown between raw MDS-UPDRS III score and protein level of ATG7 (r=−0.3002, p=0.045) and GABARAPL2 (r=−0.1110, p=0.468) (FIG. 5B). LRRK2 and HMOX1 were both able to predict a change in MDS-UPDRS III score with variation in the change of MDS-UPDRS III score at 12.5% (FIG. 5C). However, in this model LRRK2 provided a stronger effect (β=0.3594, p=0.0222) than HMOX1. The effect of LRRK2 and NF-κB was significant (p=0.0139) with 18.4% of change in MDS-UPDRS III values (FIG. 5C). The effects of NF-κB and GABARAPL2 showed significant effect on change in MDS-UPDRS III score (p=0.0128) with 18.7% effect on the change of MDS-UPDRS III score (FIG. 5C). The effects of TLR2 and TLR8 showed no significant effect on the change in MDS-UPDRS III score (p=0.567) (FIG. 5C), nor did TLR8 and ATG7 have an effect on the change in MDS-UPDRS III score (p=0.2403) (FIG. 5C). Further analysis for the effects on raw MDS-UPDRS III score showed significant effects by LRRK2/HMOX1, LRRK2/NF-κB, and NF-κB/GABARAPL2 (p=0.2093, 0.2123, and 0.4761, respectively) (FIG. 5D), whereas the other 2 pairs of predictors (TLR2/TLR8 and TLR8/ATG7) showed significant effects on raw MDS-UPDRS III score (p=0.0314 and p=0.0046, respectively) (FIG. 5D).


Similarly, correlations were made between the MDS-UPDRS III scores and gene expression of selected biomarkers. This included LRRK2 (r=0.2469, p=0.057), HMOX1 (r=0.3193, p=0.013), TLR2 (r=0.4388, p=0.000), and TLR8 (r=0.0385, p=0.770) positive correlations with the change in MDS-UPDRS-III scores (FIG. 6A). Each demonstrated relationships between decreased gene expression and improved motor function. Negative correlations were made between the change in MDS-UPDRS III scores and ATG7 (r=−0.5662, p=0.000) and GABARAPL2 (r=−0.0360, p=0.785) (FIG. 6A). Each demonstrated relationships between increased gene expression and improved motor function. Similarly, replicate correlations were seen between raw MDS-UPDRS III scores and LRRK2 (r=0.3299, p=0.010), HMOX1 (r=0.1598, p=0.223), and TLR2 (r=0.3665, p=0.004) (FIG. 6B). Negative correlations were affirmed between raw MDS-UPDRS III scores and ATG7 (r=−0.5960, p=0.000) and GABARAPL2 (r=−0.0115, p=0.930) (FIG. 6B). The data proved significant (p=0.0336) with variation in MDS-UPDRS III score change at 11.2% with both predictors (FIG. 6C). HMOX1 was a stronger predictor (β=0.2611, p=0.0747) although it failed to reach significance. Each unit increase in ddPCR HMOX1 expression increased the change in MDS-UPDRS III score by 0.0409 point. The effect of LRRK2 and TLR2 was significant (p=0.0012) with 21% of change in MDS-UPDRS III values (FIG. 6C). TLR2 provided a greater effect (β=0.4013, p=0.0018) than did LRRK2. The model predicted that 1 unit increase in ddPCR TLR2 expression increased the change in MDS-UPDRS III score by 0.0503 point. On the other hand, LRRK2 and TLR8 showed no significant effect on the change in MDS-UPDRS III scores (p=0.1449) (FIG. 6C). However, LRRK2 and ATG7 were linked to the change in MDS-UPDRS III score (p=1.12E-05) with 33% effect on the score change (FIG. 6C). ATG7 provided a greater effect (β=−0.6326, p=0.0000) than LRRK2 with an increase in 1 unit of ddPCR relative expression in ATG7 to affect the MDS-UPDRS III score change by 0.0400 point. The effect of TLR2 and TLR8 was significant (p=0.0009) with a 21.8% change in the MDS-UPDRS III score (FIG. 6C). TLR2 provided more significant effect (β=0.5124, p=0.0002) over TLR8. The model predicts that 1 unit increase in the ddPCR relative expression of TLR2 would increase the change in MDS-UPDRS III score by 0.0643 point. TLR2 and ATG7 were significantly linked to the MDS-UPDRS III score change (p=1.11E-05) with a 33% score effect (FIG. 6C). ATG7 more than TLR2 provided the greatest influence on the MDS-UPDRS III score change (β=−0.4850, p=0.0012); where an increase in 1 unit of ddPCR in ATG7 decreased the MDS-UPDRS III score change by 0.0307 point. TLR8 and ATG7 also showed significant effect on the change in MDS-UPDRS III score (p=3.8E-06) with a 35.5% effect (FIG. 6C).
