DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
[0025] Detailed Description The present disclosure is based, at least in part, on the discovery that NAPc2 abolishes antiphospholipid (aPL)-induced proinflammatory activation of monocytes, suppresses the increase of cardiolipin- and β2 glycoprotein I-reactive autoantibodies in mouse models of systemic lupus erythematosus (SLE), and prevents kidney disease in preclinical SLE models. Thus, as disclosed herein, NAPc2 not only acts as an inhibitor of TF-dependent thrombosis, but also prevents the development of pathogenic autoantibodies and organ pathology in autoimmune diseases. Accordingly, aspects of the present disclosure are directed to methods for treating a subject for an autoimmune or inflammatory condition, such as systemic lupus erythematosus and antiphospholipid syndrome, comprising administering to the subject NAPc2 or a variant thereof (e.g., NAPc2 / proline).
[0026] I. Proteins As used herein, a "protein" or "polypeptide" refers to a molecule that comprises at least four amino acid residues. As used herein, the term "wild type" refers to the endogenous version of a natural molecule present in an organism. In some embodiments, a wild type version of a protein or polypeptide is used, but in many embodiments of the present disclosure, a modified protein or polypeptide is used to generate an immune response. The above terms can be used interchangeably. A "modified protein" or "modified polypeptide", or "mutant", refers to a protein or polypeptide whose chemical structure, particularly its amino acid sequence, has been altered relative to the wild type protein or polypeptide. In some embodiments, a modified / mutated protein or polypeptide has at least one altered activity or function (with the recognition that a protein or polypeptide may have multiple activities or functions). Specifically, it is believed that a modified / mutated protein or polypeptide may be altered with respect to one activity or function, but retain wild type activity or function in other respects, such as immunogenicity.
[0027] When a protein is specifically mentioned herein, it is generally a reference to a natural (wild type) or recombinant protein, or optionally a protein with the signal sequence removed. A protein can be directly isolated from the organism in which it is native, produced by recombinant DNA / exogenous expression methods, or produced by solid phase peptide synthesis (SPPS) or other in vitro methods. In certain embodiments, there are isolated nucleic acid segments encoding polypeptides, and recombinant vectors incorporating nucleic acid sequences encoding polypeptides. The term "recombinant" can be used in conjunction with a polypeptide or the name of a particular polypeptide, and generally refers to a polypeptide produced from a nucleic acid molecule that has been manipulated in vitro, or from a nucleic acid molecule that is a product of replication of such a molecule.
[0028] In certain embodiments, the size of the protein or polypeptide (wild type or modified) is, but is not limited to, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 100, 101, 102, 103, 104, 105, 106, 107, 108, 109, 109, 109, 109, 108, 109, 109, 110, 111, 112, 113, 114, 115, , 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 73, 74, 75, 76, 77, 78, 79, 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95 , 96, 97, 98, 99, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 200, 210, 220, 230, 240, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 525, 550, 575, 600, 625, 650, 675, 700, 725, 750, 77 The domain may comprise 5, 800, 825, 850, 875, 900, 925, 950, 975, 1000, 1100, 1200, 1300, 1400, 1500, 1750, 2000, 2250, 2500 amino acid residues or more, and any range derivable therein, or derivatives of the corresponding amino acid sequence described or referenced herein. It is contemplated that the polypeptides can be mutated by truncation to be shorter than the corresponding wild type, and can also be modified by fusing or conjugating with heterologous protein or polypeptide sequences having a specific function (e.g., function for targeting or localization, enhancing immunogenicity, purification purposes, etc.). As used herein, the term "domain" refers to a distinct functional or structural unit of a protein or polypeptide, and generally refers to a sequence of amino acids having a structure or function recognized by those skilled in the art.
[0029] Polypeptides of the disclosure can include 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, or 50 (or any range derivable therein) or more variant amino acids, or can include any of the variant amino acids set forth in SEQ ID NO:1 and / or SEQ ID NO:2.

[0034] Nucleotide sequences and protein, polypeptide and peptide sequences of various genes have been disclosed before and can be found in widely recognized computerized databases.Two commonly used databases are the Genbank and GenPept databases (ncbi.nlm.nih.gov / on the World Wide Web) and the Universal Protein Resource (UniProt; uniprot.org on the World Wide Web) of the National Center for Biotechnology Information.The coding regions of these genes can be amplified and / or expressed using the techniques disclosed herein or known to those skilled in the art.
[0035] A. Mutant Polypeptides The following is a discussion of changing the amino acid subunits of proteins to create the next generation of equivalent or even improved mutant polypeptides or peptides. For example, in a protein or polypeptide sequence, certain amino acids can be replaced with other amino acids with or without significant loss of interactive binding ability with structures such as binding sites on substrate molecules. Since it is the interactive ability and properties of a protein that define its functional activity, certain amino acid substitutions can be made in a protein sequence and its corresponding DNA coding sequence to still generate a protein with similar or desirable properties. Therefore, it is contemplated herein that various changes can be made in the DNA sequence of a gene encoding a protein without significantly impairing its biological usefulness or activity.
[0036] As used herein, the term "functionally equivalent codons" refers to codons that code for the same amino acid, such as the six different codons for arginine. Also contemplated is a "neutral substitution" or "neutral mutation," which refers to an alteration of a codon that codes for a biologically equivalent amino acid.
[0037] The amino acid sequence variants of the disclosure can be substitution, insertion, or deletion variants. Mutations in the polypeptides of the disclosure can affect 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50 or more non-contiguous or contiguous amino acids of a protein or polypeptide compared to the wild type. Variants can include amino acid sequences that are at least 50%, 60%, 70%, 80%, or 90% identical (including all values and ranges therebetween) to the sequences provided or referenced herein. The variant can contain 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20 or more substituted amino acids.
[0038] It will also be understood that the amino acid and nucleic acid sequences can include additional residues, such as additional N- or C-terminal amino acids, or 5' or 3' sequences, respectively, but still be essentially identical to those shown in one of the sequences disclosed herein, so long as they meet the above criteria, including maintenance of the biological protein activity to which protein expression pertains. The addition of terminal sequences applies particularly to nucleic acid sequences, e.g., nucleic acid sequences can include various non-coding sequences adjacent to the 5' or 3' portions of the coding region.
[0039] Deletion mutants usually lack one or more residues of the native or wild-type protein. Individual residues can be deleted or several consecutive amino acids can be deleted. A stop codon can be introduced (by substitution or insertion) into the encoding nucleic acid sequence to generate a truncated protein.
[0040] Insertional mutants usually involve the addition of amino acid residues to non-terminal positions of a polypeptide. This includes the insertion of one or more amino acid residues. Terminal additions can also be produced, and terminal additions can include fusion proteins that are multimers or concatamers of one or more peptides or polypeptides described or referenced herein.
[0041] Substitution variants usually involve the exchange of one amino acid for another at one or more sites within a protein or polypeptide, and can be designed to modulate one or more properties of the polypeptide, with or without the loss of other functions or properties. Substitutions can be conservative, that is, an amino acid is replaced with one of similar chemical properties. A "conservative amino acid substitution" can involve the exchange of a member of an amino acid class with another member of the same class. Conservative substitutions are well known in the art and include, for example, the following changes: alanine to serine; arginine to lysine; asparagine to glutamine or histidine; aspartic acid to glutamic acid; cysteine to serine; glutamine to asparagine; glutamic acid to aspartic acid; glycine to proline; histidine to asparagine or glutamine; isoleucine to leucine or valine; leucine to valine or isoleucine; lysine to arginine; methionine to leucine or isoleucine; phenylalanine to tyrosine, leucine or methionine; serine to threonine; threonine to serine; tryptophan to tyrosine; tyrosine to tryptophan or phenylalanine; and valine to isoleucine or leucine. Conservative amino acid substitutions may include non-naturally occurring amino acid residues, which are usually incorporated by chemical peptide synthesis rather than by synthesis in biological systems. These include peptidomimetics or other inverted or reversed forms of amino acid moieties.
[0042] Alternatively, substitutions may be "non-conservative" such that the function or activity of the polypeptide is affected. Non-conservative changes typically involve replacing an amino acid residue with one that is chemically dissimilar, for example, replacing a polar or charged amino acid with a non-polar or uncharged amino acid, and vice versa. Non-conservative substitutions may involve exchanging a member of one amino acid class for a member of another class.
[0043] B.

In some embodiments, the disclosed methods and compositions comprise NAPc2. In some embodiments, the disclosed methods and compositions comprise NAPc2 / proline.
[0044] As used herein, NAPc2 (SEQ ID NO:1) refers to a single-chain, non-glycosylated, 85 amino acid protein (MW=9732 Da). "rNAPc2" refers to recombinant NAPc2 protein. Without wishing to be bound by theory, rNAPc2 is understood to inhibit the activity of the TF:Factor VIIa (FVIIa) complex, which initiates the TF pathway and other important pathways in coagulation via the formation of a quaternary complex after binding to the zymogen FX. Also disclosed herein are mutants of rNAPc2. In some embodiments, the disclosed therapeutic compositions comprise a protein having at least or at most 80, 81, 82, 83, 84, 85, 86, 87, 88, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99, 99.1, 99.2, 99.3, 99.4, 99.5, 99.6, 99.7, 99.8, or 99.9% sequence identity (or any range or value derivable therein) to NAPc2 (SEQ ID NO:1) or NAPc2 / proline (SEQ ID NO:2). In some embodiments, compositions comprising NAPc2 / proline are disclosed. "NAPc2 / proline" (SEQ ID NO:2) refers to a variant of NAPc2 modified to add a proline residue to the C-terminus of the sequence of NAPc2.

[0055] Aspects of the present disclosure are directed to the administration of one or more anti-inflammatory agents. In some embodiments, the anti-inflammatory agent of the present disclosure is NAPc2 or a variant thereof (e.g., NAPc2 / proline). In some embodiments, the anti-inflammatory agent is NAPc2. In some embodiments, the anti-inflammatory agent is NAPc2 / proline. Additional anti-inflammatory agents are known in the art and contemplated herein, examples of which include corticosteroids, nonsteroidal anti-inflammatory drugs (NSAIDs), TNFα inhibitors (e.g., adalimumab, certolizumab, etanercept, golimumab, infliximab), and other biologic anti-inflammatory agents (e.g., belimumab).
[0056] IV. Administration of Therapeutic Compositions The treatments provided herein may include administration of a single therapeutic agent (e.g., NAPc2, NAPc2 / proline), or a combination of therapeutic agents, such as NAPc2 (or NAPc2 / proline) and an additional anti-inflammatory agent. The treatments may be administered in any suitable manner known in the art. For example, each of the first and second treatments may be administered sequentially (at different times) or simultaneously (at the same time). In some embodiments, the first and second treatments are administered in separate compositions. In some embodiments, the first and second treatments are administered in the same composition.
[0057] Aspects of the present disclosure relate to compositions and methods, including therapeutic compositions. The therapeutic compositions may include a single therapeutic agent (e.g., NAPc2, NAPc2 / proline) or multiple different therapeutic agents. The different therapeutic agents may be administered in one composition or in two or more compositions, e.g., two compositions, three compositions, or four compositions. Combinations of various therapeutic agents may be employed.
[0058] The therapeutic agents of the present disclosure (e.g., NAPc2, NAPc2 / proline) can be administered by the same or different routes of administration. In some embodiments, the therapy is administered intravenously, intramuscularly, subcutaneously, topically, orally, transdermally, intraperitoneally, intraorbitally, by implant, by inhalation, intrathecally, intracerebroventricularly, or intranasally. In some embodiments, the therapeutic agent (e.g., NAPc2, NAPc2 / proline) is administered subcutaneously. In some embodiments, the therapeutic agent (e.g., NAPc2, NAPc2 / proline) is administered intravenously. The appropriate dosage can be determined based on the type of disease to be treated, the severity and course of the disease, the clinical condition of the individual, the individual's medical history and response to treatment, and the discretion of the attending physician.
[0059] The treatment can include various "unit doses." A unit dose is defined as comprising a predetermined amount of a therapeutic composition. The amount to be administered and the particular route and formulation are within the judgment skills of one of ordinary skill in the clinical arts. A unit dose need not be administered as a single injection, but may comprise a continuous infusion over a defined period of time. In some embodiments, a unit dose comprises a single administrable dose.
[0060] The amount administered, both according to the number of treatments and the unit dose, depends on the desired therapeutic effect. It is understood that an effective dose refers to the amount required to achieve a specific effect. In the implementation of certain embodiments, it is believed that a dose ranging from 1 μg / kg to 200 μg / kg can affect the protective capacity of these agents. Doses are contemplated to include about 0.1, 0.5, 1, 5, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 100, 105, 110, 115, 120, 125, 130, 135, 140, 145, 150, 155, 160, 165, 170, 175, 180, 185, 190, 195, and 200, 300, 400, 500, 1000 μg / kg, mg / kg, μg / day, mg / day, or any range of doses derivable therein. In some embodiments, an effective dose is at least, at most, or about 1.0, 1.1, 1.2, 1.3, 1.4, 1.5, 1.6, 1.7, 1.8, 1.9, 2.0, 2.1, 2.2, 2.3, 2.4, 2.5, 2.6, 2.7, 2.8, 2.9, 3.0, 3.1, 3.2, 3.3, 3.4, 3.5, 3.6, 3.7, 3.8, 3.9, 4.0, 4.1, 4.2, 4.3, 4.4, 4.5, 4.6, 4.7, 4.8, 4.9, 5.0, 5.1, 5.2, 5.3, 5.4, 5.5, 5.6, 5.7, 5.8, 5.9, 6.0, 6.1, 6.2, 6.3, 6.4, 6.5, 6.6, 6.7, 6.8, 6.9, 7.0, 7.1, 7.2, 7.3, 7.4, 7.5, 7.6, 7.7, 7.8, 7.9, 8.0, 8.1, 8.2, 8.3, 8.4, 8.5, 8.6, 8.7, 8.8, 8.9, 9.0, 9.1, 9.2, 9.3, 9.4, 9.5, 9.6, 9.7, 9.8, 9.9, or 10.0 μg / kg. Furthermore, such doses can be administered multiple times in a day and / or over multiple days, weeks, or months.
[0061] The precise amount of therapeutic composition to be administered also depends on the physician's judgment and is specific to each individual. Factors influencing the dosage include the physical and clinical condition of the patient, the route of administration, the intended therapeutic goal (palliation of symptoms or cure), and the efficacy, stability, and toxicity of the particular therapeutic agent or other treatments the subject may be undergoing.
[0062] Those skilled in the art will understand and appreciate that dosage units of μg / kg or mg / kg (per kg body weight) can be converted and expressed in comparable concentration units of μg / ml or mM (blood concentration). It will also be understood that uptake into the body is species and organ / tissue dependent. Applicable conversion factors and physiological assumptions for uptake and concentration measurements are well known, and those skilled in the art will be able to convert one concentration measurement to another and make reasonable comparisons and conclusions regarding doses, efficacy and results as described herein.
[0063] V. General Pharmaceutical Compositions In some embodiments, the pharmaceutical composition is administered to the subject. Various aspects may include administering an effective amount of the composition to the subject. In some embodiments, NAPc2 (or NAPc2 / proline) can be administered to the subject to prevent or treat a condition (e.g., an autoimmune or inflammatory condition). Such compositions can be dissolved or dispersed in a pharmaceutically acceptable carrier or aqueous medium.
[0064] The phrases "pharmacologically acceptable" or "pharmacologically acceptable" refer to molecular entities and compositions that do not cause adverse, allergic, or other untoward reactions when administered to animals or humans. As used herein, "pharmacologically acceptable carriers" include any solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic agents, absorption delaying agents, and the like. The use of such media and agents for pharma- ceutical active substances is well known in the art. Except insofar as any conventional media or agent is incompatible with the active ingredient, its use in immunogenic and therapeutic compositions is contemplated. Supplementary active ingredients, such as other anti-infectives and vaccines, can also be incorporated into the compositions.
[0065] The active compound can be formulated for parenteral administration, for example, for injection by intravenous, intramuscular, subcutaneous or intraperitoneal route.Generally, such compositions can be prepared as liquid solutions or suspensions;Also, solid dosage forms suitable for adding liquid to prepare liquid solutions or suspensions before injection can be prepared;And, the preparation can be emulsified.
[0066] Pharmaceutical dosage forms suitable for injectable use include sterile aqueous solutions or dispersions; formulations, for example, containing aqueous propylene glycol; and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersions. In all cases, the form must be sterile and must be fluid to the extent that easy syringability exists. It must also be stable under the conditions of manufacture and storage and must be preserved against the contaminating action of microorganisms, such as bacteria and fungi.
[0067] Proteinaceous compositions can be formulated in neutral or salt form. Pharmaceutically acceptable salts include acid addition salts (formed with free amino groups of proteins), which are formed with inorganic acids such as hydrochloric acid and phosphoric acid, or organic acids such as acetic acid, oxalic acid, tartaric acid, mandelic acid, etc. Also, salts formed with free carboxyl groups can be derived from inorganic bases such as sodium hydroxide, potassium hydroxide, ammonium hydroxide, calcium hydroxide, ferric hydroxide, etc., and organic bases such as isopropylamine, trimethylamine, histidine, procaine, etc.
[0068] The pharmaceutical compositions may contain solvents or dispersion media, including, for example, water, ethanol, polyols (e.g., glycerol, propylene glycol, liquid polyethylene glycol, and the like), suitable mixtures thereof, and vegetable oils. Proper fluidity can be maintained, for example, by the use of coating agents such as lecithin, by the maintenance of the required particle size in the case of dispersions, and by the use of surfactants. The action of microorganisms can be prevented by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, sorbic acid, thimerosal, and the like. In many cases, it is preferable to include isotonic agents, for example, sugars or sodium chloride. Prolonged absorption of the injectable compositions can be brought about by the use in the composition of agents that delay absorption, for example, aluminum monostearate and gelatin.
[0069] Sterile injectable solution can be prepared by placing the required amount of active compound in a suitable solvent containing various other ingredients as listed above as necessary, and then carrying out filtration sterilization or equivalent procedures.Generally, dispersion is prepared by incorporating various sterilized active ingredients into a sterile vehicle that contains basic dispersion medium and other necessary ingredients from those listed above.For the sterile powder for preparing sterile injectable solution, the preferred preparation method is vacuum drying and freeze-drying technology, which produces powder of active ingredient containing additional desired ingredients from the solution previously sterilized by filtration.
[0070] The administration of the composition is usually via a common route, including, but not limited to, oral or intravenous administration. Alternatively, or additionally, administration may be by orthotopic, intradermal, subcutaneous, intramuscular, intraperitoneal, or intranasal administration. Such compositions will generally be administered as pharma- ceutically acceptable compositions that include physiologically acceptable carriers, buffers, or other pharmaceutical excipients.
[0071] Upon formulation, solutions will be administered in a manner compatible with the dosage formulation, and in such amount as is therapeutically or prophylactically effective. The formulations are easily administered in a variety of dosage forms, such as the type of injectable solutions described above. EXAMPLES
[0072] The following examples are provided to demonstrate certain aspects of the present invention.Those skilled in the art should understand that the techniques disclosed in the following examples represent techniques that have been found to work well in the implementation of the present invention, and therefore are considered to constitute certain modes for its implementation.However, those skilled in the art should recognize in light of this disclosure that many changes can be made to the specific embodiments disclosed without departing from the spirit and scope of the present invention and still obtain the same or similar results.
[0073] Example 1 – Effect of rNAPc2 on aPL-induced gene expression in monocytes The effect of recombinant NAPc2 / proline (rNAPc2) on proinflammatory activation of monocytic MM1 cells by antiphospholipid antibodies (aPL) was evaluated using an established in vitro assay method [1]. MM1 cells were suspended in human plasma-containing medium to provide a source of FX recognized by rNAPc2 to inhibit TF-FVIIa. Cells were then stimulated with aPL HL5B or IgG control for 1 h and processed for genome-wide transcriptional profiling by next-generation sequencing (NGS). In separate reactions, the inhibitory effect of rNAPc2 and that of anti-TF 10H10, an established inhibitor of aPL-induced TF activation and endosomal signaling [2, 3], were evaluated. Induction of procoagulant (TF, F3) and proinflammatory responses was blocked by rNAPc2 as efficiently as the TF antibody 10H10 (Figure 1). Thus, NAPc2 is an effective inhibitor of aPL-induced signaling in monocytic cells.
[0074] Example 2 – Inhibition of autoantibody production and autoimmune pathology in the MRL / lpr mouse model of SLE by rNAPc2 Inhibition of lupus pathology was evaluated in a mouse model genetically prone to autoimmune disease. MRL / lpr mice develop an SLE-like syndrome with the appearance of high titers of aPL and β2 glycoprotein I (β2GPI) autoantibodies [1]. MRL / lpr mice develop aPL at 5–6 weeks of age, and aPL titers persist during the development of a severe SLE-like syndrome, necessitating euthanasia of the mice before they reach 15–16 weeks of age. MRL / lpr mice were treated at 11 weeks of age with 0.5 mg / kg rNAPc2 or saline control every other day for 3 weeks. At the time of randomization to treatment, both groups had similar anticardiolipin aPL titers, but aPL titers rapidly declined in rNAPc2-treated mice within 1 week of treatment and did not reappear for the duration of the experiment (Figure 2).
[0075] In a second cohort, MRL / lpr mice were similarly randomized to treatment and the reactivity of serum samples to cardiolipin or β2GPI was measured during treatment with rNAPc2. Whereas sham-treated mice showed a marked increase in antibody titers over time, mice randomized to receive rNAPc2 treatment continued to produce very low titers of autoantibodies to both cardiolipin (Figure 3A) and β2GPI (Figure 3B).
[0076] Autoimmune aPL is produced by B1 cells circulating in the blood [1]. At the end of the above experiments, the effect of rNAPc2 treatment on the reactivity of circulating B1 cells was measured using either fluorescently labeled phospholipid vesicles or β2GPI. As expected from the aPL titers measured in these mice, sham-treated MRL / lpr mice showed a high percentage of phospholipid- and β2GPI-reactive circulating B cells (Figures 4A and 4B). Staining of B cells with phospholipid vesicles was not blocked by phosphatidylcholine-loaded soluble EPCR (sEPCR-PC) but was prevented by pathogenic targets of aPL, LBPA-loaded sEPCR, or unlabeled β2GPI (Figure 4A). Consistent with the measured antibody titers, no phospholipid-reactive B cells were detected in MRL / lpr mice treated with rNAPc2. Similarly, β2GPI-reactive B cells were only found in sham-treated mice, but not in rNAPc2-treated MRL / lpr mice that exhibited lupus-like pathology (Figure 4B). β2GPI staining was specifically blocked by sEPCR-LBPA, indicating that aPL in this autoimmune mouse model have dual reactivity with EPCR-LBPA and β2GPI, and that rNAPc2 treatment effectively blocked the development of autoimmune antibodies.
[0077] Renal function was assessed by measuring urinary albumin during treatment with rNAPc2. Sham-treated control mice developed progressive albuminuria over the observation period, whereas urinary albumin concentrations did not increase in rNAPc2-treated mice (Figure 5). One mouse with high baseline albuminuria was randomized to the rNAPc2 treatment group, and this mouse showed a decrease in albuminuria at the end of the experiment. These data indicated that renal function was preserved in rNAPc2-treated MRL / lpr mice.
[0078] Renal pathology was assessed by histology in the two treatment cohorts. Renal pathology score, a composite measure of glomerular and tubular damage, was significantly improved in rNAPc2-treated mice compared to control mice (Figure 6). Additionally, immune cell infiltration was semiquantitatively scored for macrophages (CD68), T cells (CD4), and B cells (B220) on sections processed for immunohistochemistry. Treatment with rNAPc2 significantly reduced immune cell infiltration in the kidney (Figure 7).
[0079] These data demonstrate the inhibitory effect of rNAPc2 on aPL signaling in monocytes and prevention of autoimmune disease in a relevant preclinical SLE model. Suppression of B cell proliferation, which is responsible for the production of aPL in response to both cardiolipin and β2GPI, provides a rationale for therapeutic intervention in patients with severe antiphospholipid syndrome, and attenuation of renal pathology in a mouse model of SLE-like pathology supports the broad therapeutic potential of rNAPc2 in preventing and reversing end organ damage in autoimmune disease.
[0080] Example 3 – NAPc2 outperforms the anticoagulant effect of heparin in suppressing the development of aPL in lupus-prone mice The therapeutic effect of anticoagulation with low molecular weight heparin (LMWH) on the development of aPL and activation of reactive circulating B1 cells was compared with EPCR-LBPA versus NAPc2 treatment. MRL / lpr mice were randomized at 5 weeks of age to receive NAPc2 or a therapeutic dose of LMWH for 19 days. NAPc2 suppressed the development of antibodies reactive with β2GPI as well as cardiolipin, whereas heparin therapy had no effect on the antibody titers developed in MRL / lpr mice (Figures 8A and 8B). Peripheral blood was collected from these mice and stained for phospholipid and β2GPI reactivity of B1 cells. NAPc2, but not heparin, suppressed the emergence of these B cells, and staining was specifically blocked by EPCR-LBPA but not by unmodified EPCR (Figures 8C and 8D). These data demonstrate that NAPc2, but not standard heparin anticoagulation, blocks the emergence of B cells that recognize EPCR-LBPA, the pathogenic target of lupus-associated antiphospholipid syndrome.
[0081] Example 4 – NAPc2 acts as a modulator of aPL signaling in monocytes NAPc2 was shown to reprogram monocyte responses to aPL in a unique manner. Stimulation of monocytic MM1 cells in plasma with human monoclonal antiphospholipid antibodies HL5B or HL7G resulted in similar transcriptional responses (Fig. 9A). Inhibition of aPL signaling under these experimental conditions confirmed that NAPc2 effectively suppressed the aPL proinflammatory response and the upregulation of procoagulant TF (Fig. 9B). However, induction of interferon signaling was not inhibited, as indicated by the upregulation of IRF1 and IRF7 (Fig. 9C). NAPc2 showed the same inhibitory profile when the response was induced by the aPL HL7G, which cross-reacts with β2GPI and EPCR-LBPA (Fig. 2D, E). These data indicate that NAPc2 does not simply act as a suppressor of aPL signaling, but rather as a response modifier with profound anti-inflammatory properties.
