[0001] This application claims the benefit of U.S. Provisional Application No. 63 / 517,104, filed August 1, 2023. The contents of the above application are hereby incorporated herein by reference in their entirety. Background Technology

[0002] Autoimmune diseases develop when the body's immune system attacks its own healthy cells. Various types of autoimmune diseases exist, such as primary membranous nephropathy, type 1 diabetes, rheumatoid arthritis, systemic lupus erythematosus, inflammatory bowel disease, preeclampsia, multiple sclerosis, and vasculitis. Autoantibodies are antibodies that target both self-antigens and healthy cells, and are produced by pathogenic plasma cells. Autoantibodies are considered biomarkers of autoimmune diseases, and methods for targeting and depleting autoantibodies in patients with autoimmune diseases have been explored. However, treatments for autoimmune diseases often do not selectively deplete pathogenic autoantibodies, leading to the depletion of antibodies that provide an appropriate immune response against invading pathogens. Summary of the Invention

[0003] In some embodiments, this disclosure provides, in particular, a molecule that selectively targets and neutralizes and / or depletes pathogenic autoantibodies in a subject.

[0004] The molecules described herein comprise a first polypeptide and a second polypeptide, wherein the first polypeptide comprises an autoantibody-binding domain and a first Fc domain, and the second polypeptide comprises a second Fc domain. As described herein, such molecules neutralize and deplete specific pathogenic autoantibodies. In some embodiments, the targeting and depletion of autoantibodies is achieved through a mechanism that targets lysosomes of cells with immune complexes containing autoantibodies for degradation.

[0005] The molecules described herein can be used to treat autoimmune diseases, such as membranous nephropathy and / or other autoimmune diseases associated with autoantibodies targeting the M-type phospholipase A2 receptor (PLA2R). In some embodiments, the molecules comprise an autoantigen domain, which is a PLA2R autoantigen domain or a fragment or variant thereof.

[0006] In addition to containing an autoantibody-binding domain that targets the autoantibody, the molecules described herein may also contain modifications that target specific internalization receptors. In some embodiments, the molecules described herein contain an Fc domain that binds to a receptor on a cell, which induces internalization of the bound molecule. Such molecules allow binding of anti-PLA2R autoantibodies via an autoantigen domain and targeting of lysosomes for degradation via binding to the internalization receptor. In some embodiments, the molecule may contain modifications in its first and / or second Fc domains that increase its binding affinity for Fc-γ-IIB (FcγRIIB). In some embodiments, the first and / or second Fc domains of the molecule may contain modifications that increase its binding affinity for the human neonatal Fc receptor (FcRn).

[0007] In some embodiments, the molecule described herein includes an antigen-binding domain, wherein the antigen-binding domain binds to a receptor on a cell, the receptor causing the bound molecule to internalize (e.g., see...). Figure 3 In some implementations, the antigen-binding domain binds to internalizing receptors such as FcγRIIB, ASPGR, and / or FcRn. Molecules targeting internalizing receptors such as FcγRIIB can inhibit / deplete self-antigen-specific B cells on the surface of said cells (e.g., as in Chu et al.). Mol Immunol As described in 45:3926-3933 (2008), the references are incorporated herein by reference in their entirety.

[0008] All such strategies aim to deplete certain autoantibodies associated with autoimmune diseases. In some implementations, the autoantibody is an anti-PLA2R autoantibody, and the disease is membranous nephropathy or another autoimmune disease caused by an anti-PLA2R autoantibody. The molecule may contain a PLA2R autoantigen domain that targets the anti-PLA2R autoantibody, as well as an Fc domain and / or an antigen-binding domain that enables the complex (molecule and autoantibody) to target the lysosomes of the cell for selective degradation.

[0009] In one aspect, this disclosure provides a molecule comprising: a first polypeptide comprising a first Fc domain and an autoantibody-binding domain that binds to an anti-PLA2R autoantibody; and a second polypeptide comprising a second Fc domain; wherein the first Fc domain and the second Fc domain form a homodimer or heterodimer of the first polypeptide and the second polypeptide.

[0010] In some embodiments, the second polypeptide also includes an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a homodimer.

[0011] In some embodiments, the second polypeptide also includes an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a heterodimer.

[0012] In some embodiments, the second polypeptide does not contain an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a heterodimer.

[0013] In some embodiments, the autoantibody-binding domain is covalently linked to the first Fc domain. In some embodiments, the C-terminus of the autoantibody-binding domain is covalently linked to the N-terminus of the first Fc domain. In some embodiments, the N-terminus of the autoantibody-binding domain is covalently linked to the C-terminus of the first Fc domain.

[0014] In some embodiments, the first and second Fc domains form heterodimers due to a knocks-in-holes (KIH) mutation. In some embodiments, the KIH mutation comprises Y349T and T394F, according to the EU numbering scheme. In some embodiments, the first Fc domain comprises the Y349T mutation, and the second Fc domain comprises the T394F mutation. In some embodiments, the KIH mutation comprises T366W, S354C, T366S, L368A, Y407V, and Y349C, according to the EU numbering scheme. In some embodiments, the first Fc domain comprises the T366W and S354C mutations, and the second Fc domain comprises the T366S, L368A, Y407V, and Y349C mutations, according to the EU numbering scheme.

In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise one of the following mutant amino acid residues: M252Y, S254T, and T256E. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise a combination of the following mutant amino acid residues: M252Y, S254T, and T256E. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise one or more of the following mutant amino acid residues: M428L and N434S.

[0017] In some implementations, the first and / or second Fc domains contain one or more mutated amino acid residues that alter their binding to an internalization receptor on the cell, wherein the internalization receptor is capable of shuttling its cargo to the lysosome of the cell, thereby causing degradation.

[0018] In some embodiments, altered binding to the internalization receptor includes increased binding to the internalization receptor. In some embodiments, when a molecule bound to an autoantibody via its autoantibody-binding domain binds to an internalization receptor on a cell, the internalization receptor internalizes the molecule, and the autoantibody is shuttled to the cell's lysosomes for degradation. In some embodiments, the internalization receptor includes one of the following: FcγRIIB, FcRn, ASGPR, CD38, or BCMA.

[0019] In some embodiments, the first and / or second Fc domains comprise one or more mutant amino acid residues that increase binding affinity to FcγRIIB relative to the corresponding wild-type Fc domain. In some embodiments, the first and / or second Fc domains comprising one or more mutant amino acid residues do not have increased binding affinity to FcγRI, FcγRIIA167H, FcγRIIA167R, FcγRIIIA176F, FcγRIIIA176V, FcγRIIIB, FcγRIIIB, and / or FcRn relative to the corresponding wild-type Fc domain.

[0022] In some implementations, after the two molecules bind to the anti-PLA2R autoantibody, an immune complex with enhanced binding kinetics to FcγRIIB is formed relative to the anti-PLA2R autoantibody alone.

[0023] In some embodiments, enhanced binding kinetics include an increase in association rate, a decrease in dissociation rate, and / or a change in equilibrium dissociation constant.

[0128] definition To facilitate understanding of this disclosure, certain terms are defined below. The following terms, and other alternative definitions, are set forth throughout this specification. Publications and other references cited herein for the purpose of describing background and providing additional details regarding their practice are hereby incorporated by reference.

[0129] The article “a / an” is used in this text to refer to one or more (i.e., at least one) grammatical objects of the article. For example, “an element” means one element or more elements.

[0130] Application: As used herein, generally refers to the administration of the composition to a subject or system. Those skilled in the art will recognize the many routes of administration that may be used to administer the composition to a subject (e.g., a person) where appropriate. For example, in some embodiments, administration may be ocular, oral, parenteral, topical, etc. In some specific embodiments, administration may be bronchial (e.g., via bronchial infusion), buccal, dermal (which may be or include, for example, one or more of the following: topical application to the dermis, intradermal, interdermal, transdermal, etc.), enteric, intra-arterial, intradermal, gastric, intramedullary, intramuscular, intranasal, intraperitoneal, intrasheath, intravenous, intravenous, intracardiac, intra-organ (e.g., intrahepatic), mucosal, nasal, oral, rectal, subcutaneous, sublingual, topical, tracheal (e.g., via tracheal infusion), vaginal, vitreous, etc. In some specific embodiments, administration may be parenteral (e.g., via intravenous injection). In some embodiments, administration may involve intermittent (e.g., multiple doses separated by time) dosing and / or periodic (e.g., individual doses separated by the same time period) dosing. In some embodiments, administration may involve continuous dosing (e.g., infusion) for at least a selected time period.

[0131] Affinity:As is known in the art, “affinity” is a measure of the tightness with which two or more binding partners associate with each other (e.g., antibody and target antigen). Those skilled in the art understand the various assays that can be used to assess affinity, and will also understand appropriate controls for such assays. In some embodiments, affinity is assessed in a quantitative assay. In some embodiments, affinity is assessed at multiple concentrations (e.g., concentration of one binding partner at a time). In some embodiments, affinity is assessed in the presence of one or more potential competitor entities (e.g., possibly present in a relevant – e.g., physiological – environment). In some embodiments, affinity is assessed relative to a reference (e.g., a known affinity with a specific threshold – a “positive control” reference – or a known affinity with a specific threshold – a “negative control” reference). In some embodiments, affinity may be assessed relative to a contemporaneous reference. In some embodiments, affinity may be assessed relative to a historical reference. Generally, when affinity is assessed relative to a reference, affinity is assessed under comparable conditions.

[0132] Approximately or about: As used herein and when applied to one or more values ​​of interest, "about" refers to a value similar to the stated reference value. In some embodiments, unless otherwise stated or otherwise apparent from the context (other than where such a value would exceed 100% of a possible reference value), the terms "about" or "approximately" refer to a range of values ​​falling within 20% (greater or less) in either direction of the stated reference value.

[0133] Antibody:As used herein, a term refers to a polypeptide comprising a canonical immunoglobulin sequence element sufficient to confer specific binding to a particular target antigen. As is known in the art, intact antibodies, such as those produced in nature, are tetramers comprising two identical heavy-chain polypeptides and two identical light-chain polypeptides that associate with each other to form a structure commonly referred to as a “Y-shape.” Each heavy chain contains at least four domains—an amino-terminal variable (VH) domain (located at the apex of the Y structure), followed by three constant domains: CH1, CH2, and a carboxyl-terminal CH3 (located at the base of the stem of the Y). A short region called a “switch” connects the heavy-chain variable and constant regions. A “hinge” connects the CH2 and CH3 domains to the remainder of the antibody. Two disulfide bonds in this hinge region link the two heavy-chain polypeptides in the intact antibody together. Each light chain contains two domains—an amino-terminal variable (VL) domain, followed by a carboxyl-terminal constant (CL) domain—separated from each other by another “switch.” A complete antibody tetramer comprises two heavy-chain-light-chain dimers, with the heavy and light chains linked together by a single disulfide bond; two additional disulfide bonds link the heavy-chain hinge regions together, causing the dimers to link together and form a tetramer. Naturally occurring antibodies are typically also glycosylated at the CH2 domain. Each domain in a natural antibody has a structure characterized by an “immunoglobulin fold,” formed by two β-sheets (e.g., 3-chain, 4-chain, or 5-chain folds) packaged opposite each other into compressed antiparallel β-barrels. Each variable domain contains three hypervariable loops called “complementarity-determining regions” or “CDRs” (CDR1, CDR2, and CDR3) and four slightly invariant “framework” regions (FR1, FR2, FR3, and FR4). When a natural antibody folds, the FR regions form β-sheets that provide the structural framework for the domain, and the CDR loop regions from both the heavy and light chains aggregate in three-dimensional space to create a single hypervariable antigen-binding site at the apex of the Y-structure. Naturally occurring antibodies have an Fc region located at the base of the Y structure that binds to elements of the complement system and also to receptors on effector cells, including, for example, effector cells mediating cytotoxicity. The affinity and / or other binding properties of the Fc region to Fc receptors can be modulated by glycosylation or other modifications. In some embodiments, antibodies generated and / or utilized according to this disclosure comprise glycosylated Fc domains, including modified or engineered glycosylated Fc domains. In some embodiments, any polypeptide or polypeptide complex containing sufficient immunoglobulin domain sequences as found in natural antibodies can be referred to as and / or used as an "antibody," regardless of whether such polypeptide is naturally occurring (e.g., generated by an organism's response to an antigen) or produced by recombinant engineering, chemical synthesis, or other artificial systems or methods. In some embodiments, the antibody is polyclonal. In some embodiments, the antibody is monoclonal.In some embodiments, the antibody has a constant region sequence specific to mouse, rabbit, primate, or human antibodies. In some embodiments, as known in the art, the antibody sequence element is humanized, primate-based, chimeric, etc. Furthermore, as used herein, the term "antibody" in appropriate embodiments (unless otherwise stated or obvious from the context) may refer to any of the constructs or forms known or developed in the art for utilizing the structural and functional characteristics of an antibody in alternative presentations. For example, in some embodiments, the antibodies utilized according to this disclosure are presented in forms selected from, but not limited to: intact IgA, IgG, IgE, or IgM antibodies; bispecific or multispecific antibodies; antibody fragments, as used herein in the broadest sense, and encompassing a variety of antibody structures (preferably those fragments exhibiting the desired antigen-binding activity). For example, the antibodies described herein may be immunoglobulins, heavy chain antibodies, light chain antibodies, LRR-based antibodies, or other protein scaffolds with antibody-like properties, as well as any other immune-binding motifs known in the art, including, for example, Fab, Fab', Fab'2, Fab2, Fab3, F(ab')2, Fd, Fv, sdAb, scFv, SMIP, biantibodies, triantibodies, tetraantibodies, microantibodies, nanoantibodies, large antibodies, tandab, DVD, BiTe, TandAb, etc., or any combination thereof. The subunit structures and three-dimensional configurations of different types of antibodies are known in the art. In some embodiments, the antibody may lack the covalent modifications (e.g., glycan linkages) that it would have naturally. In some embodiments, the antibody may contain covalent modifications, such as glycans, cargo portions (e.g., detectable portions, therapeutic portions, catalytic portions, etc.) or attachments to other side groups (e.g., polyethylene glycol, etc.).

[0134] Antigen-binding domain:An "antigen-binding domain" refers to a portion of an antibody that binds the antigen bound by the intact antibody. Antigen-binding domains of antibodies include any naturally occurring, enzymatically obtainable, synthetic, or genetically engineered polypeptide or glycoprotein that specifically binds to an antigen to form a complex. Exemplary antigen-binding domains include, but are not limited to, Fab, Fab', Fab'2, Fab2, Fab3, F(ab')2, Fd, Fv, sdAb, scFv, SMIP, biantibodies, triantibodies, tetraantibodies, microantibodies, nanoantibodies, large antibodies, tandab, DVD, BiTe, TandAb, and any combination thereof. In some embodiments, the antigen-binding domain of the antibody described herein is scFv. In some embodiments, the antigen-binding domain of the antibody described herein is a VHH-only domain. Like whole antibody molecules, antigen-binding domains can be monospecific or multispecific (e.g., bispecific). A multispecific antigen-binding domain of an antibody may contain at least two distinct variable domains, each of which is capable of specifically binding to a single antigen or different epitopes of the same antigen.

[0135] Antibody heavy chain: As used in this article, it refers to the larger of the two types of polypeptide chains present in naturally occurring intact antibodies.

[0136] Antibody light chain: As used in this article, it refers to the smaller of the two types of polypeptide chains present in naturally occurring intact antibodies.

[0137] Synthetic antibodies: As used herein, this refers to antibodies produced using recombinant DNA technology. The term should also be interpreted as meaning antibodies generated by synthesizing a DNA molecule encoding an antibody (which expresses an antibody protein) or specifying an amino acid sequence of an antibody, wherein the DNA or amino acid sequence is obtained using synthetic DNA or amino acid sequence techniques available and well-known in the art.

[0138] antigenAs used herein, the term "antigen" refers to a molecule (e.g., peptide, polypeptide, or polysaccharide) that elicits a specific immune response. Antigen-specific immune responses, also known as adaptive immune responses, are mediated by lymphocytes (e.g., T cells, B cells, NK cells) that express antigen receptors (e.g., T cell receptors, B cell receptors). In some embodiments, the antigen is a T cell antigen and elicits a cellular immune response. In some embodiments, the antigen is a B cell antigen and elicits a humoral (i.e., antibody) response. In some embodiments, the antigen is both a T cell antigen and a B cell antigen. As used herein, the term "antigen" encompasses a full-length polypeptide and portions or immunogenic fragments of said polypeptide, as well as peptide epitopes within said polypeptide (e.g., peptide epitopes that bind to major histocompatibility complex (MHC) molecules (e.g., MHC class I or MHC class II). In some embodiments, the antigen is an autoantigen. In some embodiments, the antigen is tissue-specific or non-specific, for example, identified from cells or tissues that are targets of an autoimmune response or from healthy cells or tissues.

[0139] Autoantigen As used in this article, "autoantigen" refers to an antigen that triggers an autoimmune response. An autoantigen is an endogenous (self) antigen recognized by the immune system as non-self (i.e., foreign pathogen). Autoantigens can be proteins or immunogenic fragments of proteins, or complexes of proteins recognized by the immune system of a subject with or susceptible to an autoimmune disease.

[0140] Autoimmune diseases As used in this article, "autoimmune disease" refers to an immune response against self-antigens or autoantigens.

[0141] Related: Two events or entities are “related” to each other if the presence, level, extent, type, and / or form of one is associated with the presence, level, extent, type, and / or form of the other. For example, a particular entity (e.g., peptide, genetic marker, metabolite, microorganism, etc.) is considered to be related to a particular disease, condition, or disorder if its presence, level, and / or form are associated with the incidence, susceptibility, severity, stage, etc., of that disease, condition, or disorder (e.g., in a relevant population).

[0142] Combined structural domainAs used herein, "binding domain" refers to a portion or entity that specifically binds to a target moiety or entity. Typically, the interaction between the binding domain and its target is non-covalent. In some embodiments, the binding domain can be or comprises a moiety or entity of any chemical class, including, for example, carbohydrates, lipids, nucleic acids, metals, peptides, and small molecules. In some embodiments, the binding domain can be or comprises a peptide (or a complex thereof). In some embodiments, the binding domain can be or comprises a target-binding moiety of an antibody, cytokine, ligand (e.g., a receptor ligand), receptor, toxin, etc. In some embodiments, the binding domain can be or comprises an aptamer. In some embodiments, the binding domain can be or comprises a peptide nucleic acid (PNA). In some embodiments, the binding domain can be an antigen (e.g., an autoantigen). In some embodiments, the binding domain binds to an antibody (i.e., a "target antibody").

[0143] Effective dosage: As used herein with respect to dosage, it refers to a dose sufficient to prevent or treat the target disease or condition of the subject. The effective amount for therapeutic or preventative use will depend, for example, on the stage and severity of the disease or condition being treated, the subject's age, weight, and general health condition, as well as the judgment of the prescribing physician. The dosage will also be determined by the chosen agent, the method of administration, the time and frequency of administration, the presence, nature, and extent of any adverse side effects that may accompany the administration of the particular agent, and the desired physiological effect. Those skilled in the art will understand that various diseases or conditions may require long-term treatment involving multiple administrations, possibly using the molecules of the present invention in each or multiple rounds of administration.

[0144] coding: As used herein, “encoding” refers to the inherent property of a specific nucleotide sequence in a polynucleotide (such as a gene, cDNA, or mRNA) as a template for the synthesis of other polymers and macromolecules (having defined nucleotide sequences (i.e., rRNA, tRNA, and mRNA) or defined amino acid sequences) in biological processes, and the resulting biological properties. Therefore, if the transcription and translation of the mRNA corresponding to a gene produces a protein in a cell or other biological system, then the gene encodes that protein. Both the coding strand, whose nucleotide sequence is identical to the mRNA sequence and is typically provided in the sequence listing, and the non-coding strand, which serves as a transcription template for a gene or cDNA, can be referred to as the protein or other product encoding that gene or cDNA.

[0145] Epitope:As used herein, an epitope refers to a portion specifically recognized by an immunoglobulin (e.g., antibody) binding component. In some embodiments, an epitope consists of multiple chemical atoms or groups on the antigen. In some embodiments, such chemical atoms or groups are surface-exposed when the antigen adopts an associated three-dimensional conformation. In some embodiments, such chemical atoms or groups are physically close to each other in space when the antigen adopts such a conformation. In some embodiments, at least some of such chemical atoms or groups are physically separated from each other when the antigen adopts an alternative conformation (e.g., linearization or denaturation).

[0146] Express: As used herein, the term “expression” of a nucleic acid sequence refers to the generation of any gene product from the nucleic acid sequence. In some embodiments, the gene product may be a transcript. In some embodiments, the gene product may be a polypeptide. In some embodiments, the expression of a nucleic acid sequence involves one or more of the following: (1) generating an RNA template from a DNA sequence (e.g., by transcription); (2) processing of the RNA transcript (e.g., by splicing, editing, 5' cap formation, and / or 3' end formation); (3) translating RNA into a polypeptide or protein; and (4) post-translational modifications of the polypeptide or protein.

[0147] Excerpt:As used herein, the terms "fragment" or "part" refer to a structure that comprises a discrete portion of the whole but lacks one or more parts found throughout the whole structure. In some embodiments, a fragment consists of such discrete portions. In some embodiments, a fragment consists of or contains a characteristic structural element or part found throughout the whole. In some embodiments, the nucleotide fragment comprises or is composed of at least 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 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 or more monomeric units (e.g., nucleic acids) found in the whole nucleotide sequence. In some embodiments, the nucleotide fragment contains or is composed of at least about 5%, 10%, 15%, 20%, 25%, 30%, 25%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or more of monomeric units (e.g., nucleic acids) found in the whole nucleotide. In some embodiments, the polypeptide or protein fragment comprises or is composed of at least 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 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 or more monomeric units (e.g., amino acids) found in the whole polypeptide or protein. In some embodiments, the polypeptide or protein fragment comprises or is composed of at least about 5%, 10%, 15%, 20%, 25%, 30%, 25%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, 96%, 97%, 98%, 99% or more of monomeric units (e.g., amino acids) found in the whole polypeptide or protein. In some embodiments, the whole material or entity may be referred to as the "parent" of the fragment.

[0148] identityAs used herein, the term "identity" refers to the overall relevance between polymer molecules, such as nucleic acid molecules (e.g., DNA molecules and / or RNA molecules) and / or polypeptide molecules. In some embodiments, polymer molecules are considered "substantially identical" to each other if their sequences are at least 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 95%, or 99% identical. For example, the percentage of identity between two nucleic acid or polypeptide sequences can be calculated by comparing the two sequences for optimal comparison purposes (e.g., vacancies can be introduced in one or both of the first and second sequences to achieve optimal alignment, and dissimilar sequences can be ignored for comparison purposes). In some embodiments, the length of the sequence compared for comparison purposes is at least 30%, at least 40%, at least 50%, at least 60%, at least 70%, at least 80%, at least 90%, at least 95%, or substantially 100% of the length of the reference sequence. Nucleotides at corresponding positions are then compared. The molecules are considered identical at a position in the first sequence when that position is occupied by the same residue (e.g., a nucleotide or amino acid) as the corresponding position in the second sequence. The percentage of identity between two sequences is a function of the number of common positions shared by the sequences, taking into account the number of vacancies introduced for optimal alignment and the length of each vacancies. Sequence comparisons and the determination of the percentage of identity between two sequences can be accomplished using mathematical algorithms. For example, the percentage of identity between two nucleotide sequences can be determined using the algorithm of Meyers and Miller (CABIOS, 1989, 4: 11-17), which has been incorporated into the ALIGN program (version 2.0). In some exemplary embodiments, nucleic acid sequence comparisons using the ALIGN program employ a PAM120 weighted residue table, a vacancy length penalty of 12, and a vacancy penalty of 4. Alternatively, the percentage of identity between two nucleotide sequences can be determined using the GAP program in the GCG software package with an NWSgapdna.CMP matrix.

[0149] Human antibodies: As used herein, it is intended to include antibodies having variable and constant regions generated (or assembled) from human immunoglobulin sequences. In some embodiments, although the amino acid sequence of the antibody (or antibody component) contains residues or elements not encoded by human germline immunoglobulin sequences (e.g., containing sequence variations that may have been introduced (initially) through in vitro random or site-specific mutagenesis or in vivo somatic mutations), such as in one or more CDRs and particularly CDR3, the antibody (or antibody component) may be considered " human ".

[0150] immune cellsAs used herein, the term "immune cell" refers to a cell that participates in an immune response (e.g., promotes an immune response). Examples of immune cells include, but are not limited to, T lymphocytes, natural killer (NK) cells, macrophages, monocytes, dendritic cells, neutrophils, eosinophils, mast cells, platelets, large granular lymphocytes, Langerhans cells, plasma cells, or B lymphocytes. The source of immune cells (e.g., T lymphocytes) may be obtained from the subject.

[0151] immune mediators As used herein, the term "immune mediator" refers to any molecule that affects the cells and processes involved in an immune response. Immune mediators include cytokines, chemokines, soluble proteins, enzymes, and cell surface markers.

[0152] Immune response: As used herein, it refers to the cellular and / or systemic response to an antigen that occurs when immune cells identify an antigen molecule as foreign and induce antibody formation and / or activate autologous or other immune cells to remove the antigen.

[0153] Immunoglobulins or Ig: As used in this article, "antibody" refers to a class of proteins that function as antibodies. Antibodies expressed by B cells are sometimes called BCRs (B cell receptors) or antigen receptors. This class of proteins includes five members: IgA, IgG, IgM, IgD, and IgE. IgA is a primary antibody found in bodily secretions such as saliva, tears, breast milk, gastrointestinal secretions, and mucus secretions from the respiratory and genitourinary tracts. IgG is the most common circulating antibody. IgM is the major immunoglobulin produced in the primary immune response of most subjects. It is the most effective immunoglobulin in agglutination, complement fixation, and other antibody responses, and is important in the defense against bacteria and viruses. IgD is an immunoglobulin that does not have known antibody functions but can act as an antigen receptor. IgE is an immunoglobulin that mediates immediate-type hypersensitivity reactions by inducing the release of mediators from mast cells and basophils upon exposure to allergens.

[0154] improve , Increase or reduceAs used herein, the terms “improvement,” “increase,” or “decrease,” or grammatically equivalent comparative terms, refer to a value relative to an equivalent reference measurement. For example, in some embodiments, an assessment value obtained with the target agent may be “improved” relative to an assessment value obtained with an equivalent reference agent. Alternatively or additionally, in some embodiments, an assessment value obtained in the target subject or system may be “improved” relative to an assessment value obtained in the same subject or system under different conditions (e.g., before or after an event such as administration of the target agent) or in different comparable subjects (e.g., in equivalent subjects or systems different from the target subject or system in the presence of one or more indicators of a specific target disease, condition, or ailment, or in prior exposure to the ailment or agent, etc.). In some embodiments, comparative terms refer to statistically relevant differences (e.g., whose prevalence and / or magnitude are sufficient to achieve statistical relevance). In the given context, those skilled in the art will recognize or will be able to readily determine the degree and / or prevalence of the difference required or sufficient to achieve such statistical significance.

[0155] Separate: As used herein, "isolated" refers to substances that have been altered or removed from their natural state. For example, nucleic acids or polypeptides naturally present in living organisms are not "isolated," but the same nucleic acids or polypeptides that are partially or completely separated from their natural coexisting substances are "isolated." Isolated nucleic acids or polypeptides may exist in substantially purified forms or may exist in non-natural environments such as host cells.

This term encompasses the disruption and / or influence of natural signals or responses, thereby mediating a beneficial therapeutic response in subjects, preferably humans.

[0160] Nucleic acidAs used herein, "nucleic acid" refers to a polymer of at least three nucleotides. In some embodiments, the nucleic acid includes DNA. In some embodiments, the nucleic acid includes RNA. In some embodiments, the nucleic acid is single-stranded. In some embodiments, the nucleic acid is double-stranded. In some embodiments, the nucleic acid comprises both single-stranded and double-stranded portions. In some embodiments, the nucleic acid comprises a backbone containing one or more phosphodiester-linked bonds. In some embodiments, the nucleic acid comprises a backbone containing both phosphodiester-linked and non-phosphodiester-linked bonds. For example, in some embodiments, the nucleic acid may comprise a backbone containing one or more thiophosphate or 5'-N-phosphoamide bonds and / or one or more peptide bonds, such as those in "peptide nucleic acid". In some embodiments, the nucleic acid comprises one or more or all of the natural residues (e.g., adenine, cytosine, deoxyadenosine, deoxycytidine, deoxyguanosine, deoxythymidine, guanine, thymine, uracil).

In some embodiments, the nucleic acid has a nucleotide sequence encoding a functional gene product such as RNA or a polypeptide. In some embodiments, the nucleic acid has a nucleotide sequence comprising one or more introns. In some embodiments, the nucleic acid can be prepared by isolating from a natural source, enzymatically synthesizing (e.g., by polymerase based on a complementary template, e.g., in vivo or in vitro), replicating in a recombinant cell or system, or by chemical synthesis. In some implementations, the length of the nucleic acid is at least 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65, 70, 75, 80, 85, 90, 95, 100, 110, 120, 130, 140, 150, 160, 170, 180, 190, 20, 225, 250, 275, 300, 325, 350, 375, 400, 425, 450, 475, 500, 600, 700, 800, 900, 1000, 1500, 2000, 2500, 3000, 3500, 4000, 4500, 5000 or more residues.

For example, the first and second nucleic acid sequences are operatively linked when they are functionally related. Similarly, if a promoter affects the transcription or expression of a coding sequence, the promoter is operatively linked to the coding sequence. Typically, the operatively linked DNA sequences are contiguous and, when two protein-coding regions need to be linked, are within the same reading frame.

[0162] Pharmaceutical Composition As used herein, "active agent" refers to an active agent formulated with one or more pharmaceutically acceptable carriers. In some embodiments, the active agent of interest is present at a unit dose suitable for administration in a treatment regimen that, when administered to the relevant population, shows a statistically significant probability of achieving the intended therapeutic effect. In some embodiments, the pharmaceutical composition may be specifically formulated for administration in solid or liquid form, including those suitable for: oral administration, such as drench (aqueous or non-aqueous solution or suspension), tablets (e.g., those tablets targeted for absorption via buccal, sublingual, and systemic administration), pellets, powders, granules, pastes for application to the tongue; parenteral administration, such as by subcutaneous, intramuscular, intravenous, or epidural injection, as, for example, a sterile solution or suspension or sustained-release formulation; topical administration, such as as a cream, ointment, controlled-release patch, or spray to the skin, lungs, or mouth; intravaginal or rectal administration, such as as a vaginal suppository, cream, or foam; sublingual; ocular; transdermal; or nasal, pulmonary administration, and application to other mucosal surfaces.

[0163] Polynucleotides: As used herein, "nucleotide chain" refers to a nucleotide chain. Furthermore, nucleic acids are polymers of nucleotides. Therefore, nucleic acids and polynucleotides, as used herein, are interchangeable. Those skilled in the art will generally know that nucleic acids are polynucleotides that can be hydrolyzed into monomeric "nucleotides." Monomeric nucleotides can be hydrolyzed into nucleosides. As used herein, polynucleotides include, but are not limited to, all nucleic acid sequences obtained by any means available in the art, including, but not limited to, recombinant methods (i.e., cloning nucleic acid sequences from recombinant libraries or cell genomes using common cloning techniques and PCR, etc.) and synthetic methods.

[0164] protein:As used herein, a polypeptide (i.e., a string of at least two amino acids linked together by peptide bonds) is used. Therefore, protein and polypeptide are used interchangeably as used herein. A protein may include portions other than amino acids (e.g., it may be a glycoprotein, proteoglycan, etc.) and / or may be otherwise processed or modified. Those skilled in the art will understand that a “protein” can be a complete polypeptide produced by a cell (with or without a signal sequence) or can be its characteristic portion. Those skilled in the art will understand that a protein may sometimes include, for example, more than one polypeptide linked by one or more disulfide bonds or associated by other covalent or non-covalent means. A polypeptide may contain L-amino acids, D-amino acids, or both, and may contain any of a variety of amino acid modifications or analogs known in the art. Useful modifications include, for example, terminal acetylation, amidation, methylation, etc. In some embodiments, a protein may contain native amino acids, non-native amino acids, synthetic amino acids, and combinations thereof. The term “peptide” is generally used to refer to polypeptides with a length of less than about 100 amino acids, less than about 50 amino acids, less than 20 amino acids, or less than 10 amino acids. In some implementations, the protein is an antibody, an antibody fragment, its biologically active portion, and / or its characteristic portion.

[0165] Specific binding: As used herein, the term "specific binding" for antigen-binding domains (such as those found in antibodies) refers to an antigen-binding domain that recognizes a specific antigen but substantially does not recognize or bind to other molecules in a sample. For example, an antigen-binding domain that specifically binds to an antigen from one species may also bind to antigens from one or more other species. However, this cross-species reactivity itself does not change the classification of the antigen-binding domain as specific. In another instance, an antigen-specific antigen-binding domain may also bind to different allelic forms of an antigen. However, this cross-reactivity itself does not change the classification of the antigen-binding domain as specific. In some cases, the terms "specific binding" or "specific binding" may be used with respect to the interaction of an antigen-binding domain with a second chemical substance, meaning that the interaction depends on the presence of a specific structure (e.g., an antigenic determinant or epitope) on the chemical substance; for example, the antigen-binding domain recognizes and binds to a specific protein structure rather than a typical protein. If the antigen-binding domain is specific to epitope "A", then in a reaction containing labeled "A" and the antigen-binding domain, the presence of a molecule containing epitope A (or free unlabeled A) will reduce the amount of labeled A binding to the antigen-binding domain.

[0166] Subjects:As used herein, "organism" refers to an organism, such as a mammal (e.g., a human, a non-human mammal, a non-human primate, a primate, a laboratory animal, a mouse, a rat, a hamster, a gerbil, a cat, or a dog). In some embodiments, the human subject is an adult, adolescent, or pediatric subject. In some embodiments, the subject has a disease, condition, or disorder, such as a disease, condition, or disorder that can be treated as provided herein, such as an autoimmune disease. In some embodiments, the subject is susceptible to a disease, condition, or disorder; in some embodiments, susceptible subjects tend to and / or show an increased risk of developing the disease, condition, or disorder (compared to the average risk observed in a reference subject or population). In some embodiments, the subject exhibits one or more symptoms of a disease, condition, or disorder.

[0171] Some autoimmune diseases are driven by autoantibodies that produce an immune response to self-antigens (i.e., self-antigens). Although certain autoantibody-antigen pairs and their effects in autoimmune diseases (e.g., PLA2R and primary membranous nephropathy) have been identified, many are poorly controlled with current treatments. Current standard of care involves suppressing the autoimmune response by inhibiting or depleting intact immune components or cell populations, including those necessary for a healthy immune response to foreign pathogens. Current treatments include glucocorticoids, antibodies targeting plasma cells, antibodies targeting FcRn (“FcRn inhibitors”), and plasmapheresis. FcRn inhibitors lead to pan-IgG depletion and often result in incomplete depletion of autoantibodies.

[0172] This disclosure covers the selective depletion of autoantibodies (i.e., anti-PLA2R autoantibodies) for the treatment of autoimmune diseases (e.g., membranous nephropathy). In some embodiments, the molecule described herein comprises a first polypeptide comprising a first Fc domain and an autoantibody-binding domain that binds to the autoantibody (i.e., anti-PLA2R autoantibody); and a second polypeptide comprising a second Fc domain; wherein the first Fc domain and the second Fc domain form a homodimer or heterodimer of the first polypeptide and the second polypeptide. In some embodiments, the second polypeptide further comprises an autoantibody-binding domain that binds to the autoantibody (i.e., anti-PLA2R autoantibody). In some embodiments, the autoantibody-binding domains in the first polypeptide and the second polypeptide are identical, and the molecule is a homodimer. In some embodiments, the autoantibody-binding domains in the first polypeptide and the second polypeptide are different, and the molecule is a heterodimer. In some embodiments, the second polypeptide does not further comprise an autoantibody-binding domain that binds to the autoantibody (i.e., anti-PLA2R autoantibody), and the molecule is a heterodimer.

[0173] This disclosure particularly provides molecules that selectively target and deplete autoantibodies, for example, by targeting an internalization receptor to which the autoantibody binds to a cell and internalizes the complex into the cell for lysosomal degradation. In some embodiments, the autoantibody-binding domain comprises an autoantigen. For example, if the specific autoantibody to be targeted is an anti-PLA2R autoantibody (e.g., for treating membranous nephropathy), the autoantigen domain may comprise a PLA2R autoantigen domain. In addition to comprising an autoantibody-binding domain, the molecule may also include modifications in its first and / or second Fc domains that increase its binding to an internalization receptor or endocytic receptor on the cell surface (e.g., internalizing the ligand and targeting the ligand to a lysosome). In some embodiments, the molecule may comprise an antigen-binding domain that binds to an internalization receptor or endocytic receptor on the cell surface (e.g., internalizing the ligand and targeting the ligand to a lysosome).

[0174] Membranous nephropathy and PLA2R In some embodiments, the molecules described herein can be used to treat primary membranous nephropathy and other autoimmune diseases associated with autoantibodies targeting the M-type phospholipase A2 receptor (PLA2R), achieved by including an autoantibody-binding domain comprising a fragment or variant of the PLA2R autoantigen or thereof.

[0175] Membranous nephropathy (MN) is an autoimmune disease caused by antibodies against the M-type phospholipase A2 receptor (PLA2R). MN presents as a slowly progressive kidney disease. Patients with MN may exhibit symptoms of nephrotic syndrome, including edema and proteinuria.

[0176] The annual incidence of membranous nephropathy is 10–12 per million people in North America and 2–17 per million people in Europe. Antibodies against PLA2R are found in approximately 70% of membranous nephropathy cases (see Ronco et al., Membranous nephropathy). Nat Rev Dis Primers 7, 69 (2021)). Binding of PLA2R antibodies at the glomerular basement membrane (GBM) leads to the formation of immune complexes at the GBM. It has been shown that deposition of IgG and complement system components at the GBM induced by PLA2R antibody binding contributes to GBM thickening and damage to the glomerular filtration barrier. (See Gu et al., “Mechanisms of Primary Membranous Nephropathy”). Biomolecules Volume 11, 4513 (2021)).

[0177] Treatment for membranous nephropathy may include non-immunosuppressive therapy for nephrotic symptoms. For example, treatment for edema includes sodium restriction and loop diuretics. Statins are recommended for patients with persistent proteinuria and hypercholesterolemia. Early immunosuppressive therapy for membranous nephropathy includes the use of prednisolone and other immunosuppressive drugs such as cyclophosphamide. However, this treatment has been found to have side effects, including anemia, leukopenia, infection, and infertility (see Ronco et al.). Nat Rev Dis Primers 7:69 (2021)).

[0178] This disclosure recognizes that further selective introduction can be made to maintain basic immunity and enhance the efficacy of antibodies, for example, targeting foreign pathogens such as viral antigens. The molecules described herein include further selectivity for target autoantibodies involved in autoimmune diseases. In some embodiments, this strategy includes utilizing the PLA2R autoantigen domain or fragments or variants thereof to target and destroy anti-PLA2R autoantibodies, thereby eliminating autoimmune responses involved in membranous nephropathy.

In some embodiments, the molecules described herein comprise a first polypeptide comprising a first Fc domain and an autoantibody-binding domain that binds to the autoantibody (i.e., anti-PLA2R autoantibody); and a second polypeptide comprising a second Fc domain; wherein the first Fc domain and the second Fc domain form a homodimer or heterodimer of the first polypeptide and the second polypeptide. In some embodiments, the second polypeptide further comprises an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a homodimer. In some embodiments, the second polypeptide further comprises an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a heterodimer. In some embodiments, the second polypeptide does not comprise an autoantibody-binding domain that binds to the anti-PLA2R autoantibody, and the molecule is a heterodimer.

[0180] In some implementations, the first and / or second polypeptide also includes an antigen-binding domain (e.g., a Fab domain).

[0181] In some embodiments, the first and second polypeptides of the molecule described herein may be in the form of a fusion protein. In some embodiments, the first and second polypeptides of the molecule described herein may be in the form of a chemically conjugated molecule.

[0182] In some embodiments, the first and / or second Fc domains contain one or more mutant amino acid residues and have increased binding affinity for internalizing receptors (e.g., FcγRIIB) relative to the corresponding wild-type Fc domains.

[0183] In some embodiments, an immune complex is formed upon binding of one or two molecules to an autoantibody (i.e., an anti-PLA2R autoantibody). In some embodiments, the immune complex formed with one molecule described herein and an autoantibody (i.e., an anti-PLA2R autoantibody) exhibits enhanced binding kinetics with FcγRIIB, relative to an immune complex comprising an autoantibody (i.e., an anti-PLA2R autoantibody) binding to one corresponding molecule having a wild-type Fc domain. In some embodiments, the immune complex formed with two molecules described herein and an autoantibody (i.e., an anti-PLA2R autoantibody) exhibits enhanced binding kinetics with FcγRIIB, relative to an immune complex comprising an autoantibody (i.e., an anti-PLA2R autoantibody) comprising two corresponding molecules having a wild-type Fc domain. Such enhanced binding kinetics increase the clearance of the immune complex.

In some embodiments, the autoantibody-binding domain comprises a Fab domain, scFv domain, VHH, Fc domain, peptide sequence, mimic epitope, and / or any portion of the self-antigen domain targeted by the autoantibody.

[0185] In some implementations, the autoantibody binding domain described herein prevents autoantibodies from binding to their homologous autoantigens (e.g., autoantibodies against PLA2R autoantigens).

[0186] Autoantigen In some embodiments, the molecule includes an autoantibody-binding domain containing an autoantigen or a fragment or variant thereof. Such autoantigen domains target autoantibodies associated with various autoimmune diseases.

[0209] The Fc domain contained in the molecule may comprise any of the five major classes of antibodies: IgA, IgD, IgE, IgG, and IgM. In some embodiments, the conventional antibody comprises an IgG antibody.

In some embodiments, the molecule comprises a first and / or second Fc domain as a human IgG1 isotype. Additionally, in some embodiments, the Fc domain may comprise any specific heavy chain constant domain corresponding to different classes of immunoglobulins (including α, δ, ε, γ, and μ). In some embodiments, the conventional antibody is a complete IgG1 antibody or other antibody classes or isotypes as described herein (see, for example, Hudson et al.). Nat.

[0210] The Fc region of the antibody contained in the molecules described herein can bind to elements of the complement system and also to receptors on effector cells, including, for example, effector cells mediating cytotoxicity. As is known in the art, the affinity and / or other binding properties of the Fc region to Fc receptors can be modulated by glycosylation or other modifications. In some embodiments, the molecules described herein comprise glycosylated Fc domains, including modified or engineered glycosylated Fc domains. In some embodiments, the molecules are naturally occurring (e.g., produced by an organism that responds to an antigen) or generated through recombinant engineering, chemical synthesis, or other artificial systems or methods.

[0211] In some embodiments, one or more modifications to the Fc domain increase the clearance of immune complexes formed by one or more molecules described herein that bind to an autoantibody (e.g., an anti-PLA2R autoantibody). In some embodiments, one or more modifications to the Fc domain can induce selective targeting and / or clearance of immune complexes formed by one or more molecules described herein that bind to a target antibody. For example, in some embodiments, where, after two molecules bind to an autoantibody (e.g., an anti-PLA2R autoantibody), an immune complex is formed with enhanced binding kinetics to one or more Fc receptors (e.g., FcγRIIB) relative to an immune complex containing two corresponding molecules having a wild-type Fc domain. The binding kinetics may be characterized by, for example, an increase in association rate, a decrease in dissociation rate, and / or a change in the equilibrium dissociation constant. In some embodiments, the Fc domain preferentially binds to immune cells expressing FcγRIIB relative to immune cells expressing FcγRIIA. In some embodiments, the Fc domain has essentially no binding affinity for cells that do not express FcγRIIB (e.g., T cells, NK cells, neutrophils, and / or eosinophils). In some embodiments, the immune cells expressing FcγRIIB are B cells, monocytes, and / or basophils.

[0212] In some embodiments, enhanced binding kinetics includes an increase of at least 10% in the binding affinity of the immune complex to one or more Fc receptors (e.g., FcγRIIB). In some embodiments, enhanced binding kinetics includes a binding affinity of at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, or at least 50% or higher.

[0215] Exemplary Fc domain sequences used according to this disclosure are shown in Table 3 below. It should be understood that any of these Fc domain sequences can be used in the first or second polypeptide of the molecules of this disclosure. It should also be understood that any of the exemplary Fc domain sequences having a club-shaped mutation (identified by the reference symbol “club”) can be used together with any of the exemplary Fc domain sequences having a mortar-shaped mutation (identified by the reference symbol “mortar”) to prepare heterodimeric molecules. In some embodiments, the Fc domain sequences shown in Table 3 can be used in pairs to prepare heterodimeric molecules, for example, but not limited to, based on the numerical references in Table 3 (e.g., human IgG1 Fc 1.1 club-shaped can be used with human IgG1 Fc 1.1 mortar-shaped, human IgG1 Fc 1.2 club-shaped can be used with human IgG1 Fc 1.2 mortar-shaped, etc.). It should also be understood that the Fc domain sequences mentioned in Table 3 that can be used for "antigen arms for Ag depletion" (i.e., in peptides that also contain an autoantibody binding domain) or "free arms for Ag depletion" (i.e., in peptides that do not contain an autoantibody binding domain) are intended to be exemplary and non-limiting only. That is, the Fc domain sequences in Table 3 that are identified as being usable for "antigen arms for Ag depletion" may be used for "free arms for Ag depletion" in some embodiments, and the Fc domain sequences in Table 3 that are marked as being usable for "free arms for Ag depletion" may be used for "antigen arms for Ag depletion" in some embodiments.

[0257] Mutations that increase binding to internalization receptors In some embodiments, additional mutations are introduced into the Fc domain of the molecule described herein to target and internalize ligands and to target the ligands to lysosomal cell surface receptors (i.e., internalization receptors or endocytic receptors). By modifying the Fc domain to increase binding to internalization receptors, the molecule described herein and its bound autoantibodies are targeted for internalization and lysosomal degradation.

[0258] In some embodiments, the molecule includes a first and / or a second Fc domain containing one or more mutant amino acid residues that alter its binding to an internalization receptor on a cell, wherein the internalization receptor is capable of shuttling its cargo to the lysosomes of the cell, thereby leading to degradation. In some embodiments, the altered binding to the internalization receptor includes an increased binding to the internalization receptor. Without wishing to be bound by any theory, once the molecule binding to the autoantibody binds to the internalization receptor on the cell, the internalization receptor internalizes the molecule and the autoantibody is shuttled to the lysosomes of the cell for degradation.

[0259] Exemplary internalizing receptors include, but are not limited to, FcγRIIB, FcRn, ASGPR, BCMA, CD38, SLAMF7, GPCR5D, or CD138.

[0260] In some embodiments, the first and / or second Fc domains comprise one or more mutant amino acid residues that enhance binding to human FcγR (particularly FcγRIIB). In some embodiments, according to the EU numbering scheme, such mutations comprise at least one of the following mutant amino acid residues: S267E and L328F. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise a combination of the following mutant amino acid residues: S267E and L328F. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise the mutant amino acid residue P238D. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise at least one of the following mutant amino acid residues: L234A, L235A, and P238D. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise the following mutant amino acid residues: L234A, L235A, and P238D. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise at least one of the following mutant amino acid residues: L234A, L235A, P238D, and P329G. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise at least one of the following mutant amino acid residues: L234A, L235A, and P238D.

In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise at least one of the following mutant amino acid residues: N297A and P238D. In some implementations, according to the EU numbering scheme, the first and / or second Fc domains contain the following mutant amino acid residues: N297A and P238D.

[0261] In some embodiments, one or more Fc mutations are introduced to increase binding to the human neonatal receptor (FcRn). In some embodiments, the Fc domain is the IgG1 Fc domain. Human IgG1 naturally binds to FcRn at acidic pH, which allows it to be recycled back to the cell surface after binding to FcRn and internalization into the cell without being degraded in lysosomes. In some embodiments, the Fc mutations include mutations that increase binding to FcRn in a neutral pH environment (e.g., the extracellular environment). Without wishing to be bound by any theory, such mutations are included in the molecules described herein to increase the binding of the Fc domain to FcRn on the cell surface in a neutral pH environment, thereby increasing the receptor-mediated internalization into the cell and the shuttle transport of (molecule-bound) autoantibodies to lysosomes.

[0262] In some embodiments, the first and / or second Fc domains contain one or more mutant amino acid residues that increase binding to FcRn at neutral or near-neutral pH (e.g., between about 6.8 and 7.5). In some embodiments, the first and / or second Fc domains contain a human IgG1 isotype and remain bound to FcRn upon entry into an environment with an acidic pH and / or a low calcium concentration (e.g., endosomes within a cell). In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains contain at least one of the following mutant amino acid residues: M252Y, S254T, T256E, H433K, and N434F. In some embodiments, according to the EU numbering scheme, such mutations include combinations containing the following mutations: M252Y, S254T, T256E, H433K, and N434F (i.e., "MST-HN"). In some implementations, according to the EU numbering scheme, the first and / or second Fc domains contain a combination of the following mutant amino acid residues: M252Y, S254T, T256E, H433K, and N434F (i.e., "MST-HN").

[0263] In some embodiments, the first and / or second Fc domains comprise at least one mutant amino acid sequence that reduces binding to one or more Fc-γ receptors (FcγRs). Such modifications can prevent immune cross-linking leading to an inflammatory response (i.e., immune cross-linking of the molecule, autoantibodies, and FcγRs). Such mutations can focus the molecule's primary mechanism of action on (i.e.) the targeted internalization and subsequent degradation of autoantibodies. In some embodiments, according to the EU numbering scheme, the first and / or second Fc domains comprise at least one of the following mutant amino acid residues: G236R and L328R.

[0264] In some embodiments, the molecule described herein may comprise any combination of the aforementioned Fc mutations that alter the binding to the internalizing receptor or Fc receptor. In some embodiments, the molecule described herein comprises an Fc domain comprising a combination of the “MST-HN” modification and the “RR” mutation described herein. In some embodiments, the molecule described herein comprises an Fc domain comprising a combination of the “MST-HN” modification and the “P238D” mutation described herein. In some embodiments, the molecule described herein comprises an Fc domain comprising a combination of the “MST-HN” modification and the “RR” and “P238D” mutations described herein.

[0265] i. Exemplary FcγRIIB mutation In some embodiments, the Fc domain contains one or more amino acid mutations that increase affinity for FcγRIIB. In some embodiments, FcγRIIB is human FcγRIIB. In some embodiments, FcγRIIB is mouse FcγRIIB.

[0266] In some embodiments, the Fc domain is used in the molecule described herein, which contains one or more mutations that enhance the binding kinetics of an immune complex comprising one or more molecules binding to a target antibody to FcγRIIB. In some embodiments, enhanced binding kinetics include a binding affinity of at least 15%, at least 20%, at least 25%, at least 30%, at least 35%, at least 40%, at least 45%, or at least 50% or higher. In some embodiments, enhanced binding kinetics include an increase in the affinity, stability, strength, frequency, and / or duration of the binding between the immune complex and FcγRIIB. In some embodiments, enhanced binding kinetics include an increase in the association rate, a decrease in the dissociation rate, and / or a change in the equilibrium dissociation constant.

[0267] In some embodiments, the molecules described herein having first and second Fc domains contain one or more mutations in the first and / or second Fc domains to increase binding to FcγRIIB, wherein, after the two molecules bind to the target antibody, an immune complex with enhanced binding kinetics to FcγRIIB is formed relative to an immune complex containing the target antibody that binds to the two corresponding molecules having wild-type Fc domains. Not wishing to be bound by any theory, the molecules described herein may have one or more mutations that increase binding affinity to FcγRIIB, but the binding affinity of the individual molecule to FcγRIIB is moderate. In some embodiments, the molecule binds to FcγRIIB with an affinity in the range of about 1 µM to 0.001 µM. In some embodiments, the molecule binds to FcγRIIB with an affinity in the range of about 1 µM to 0.01 µM. In some embodiments, the molecule binds to FcγRIIB with an affinity in the range of about 0.1 µM to 0.01 µM. In some embodiments, when two or more molecules are present in an immune complex containing a target antibody, such mutations, when introduced into the Fc domain of the molecule described herein, confer an affinity-mediated binding effect to FcγRIIB. In some embodiments, the molecule described herein has increased binding to FcγRIIB when the immune complex contains two molecules that bind to the target antibody, compared to an immune complex containing only one molecule that binds to the target antibody. While not wishing to be bound by any theory, this affinity-mediated effect allows for selective binding and depletion of the immune complex, and allows for weaker binding (and therefore depletion) of the molecule when it is not part of the immune complex. These characteristics allow the molecule described herein to circulate in the subject's bloodstream for a longer period before being cleared by FcγRIIB-mediated internalization and degradation.

[0268] Furthermore, this disclosure provides Fc domain mutations that achieve binding affinity for FcγRIIB to confer affinity-mediated effects, thereby utilizing the benefits and additional selectivity described herein.

[0270] In some embodiments, according to the EU numbering scheme, the Fc domain mutation includes one or more of the following mutations: E233V, L234D, L235F, G236R, G237D, S239L, S267D, R292Q, H268P, S298G, T299A, A327L, L328A, A330H, or E333I. In some embodiments, according to the EU numbering scheme, the Fc domain contains the following mutation set: E233V, L234D, L235F, G236R, G237D, S239L, S267D, R292Q, H268P, S298G, T299A, A327L, L328A, A330H, and E333I (e.g., see SEQ ID NO: 115, 116, and 140).

In some embodiments, according to the EU numbering scheme, the Fc domain contains the following mutation set: P238D and D270E (e.g., see SEQ ID NO: 127, 128 and 146).

[0277] In some embodiments, according to the EU numbering scheme, the Fc domain mutation includes one or both of the following mutations: P238D and P271G. In some embodiments, according to the EU numbering scheme, the Fc domain contains the following mutation set: P238D and P271G (see, for example, SEQ ID NO: 129, 130 and 147).

[0278] In some embodiments, according to the EU numbering scheme, the Fc domain mutation includes one or more of the following mutations: P238D, D270E, or P271G. In some embodiments, according to the EU numbering scheme, the Fc domain contains the following mutation set: P238D, D270E, and P271G (see, for example, SEQ ID NO: 131, 132, and 148).

[0279] In some embodiments, according to the EU numbering scheme, the Fc domain mutation includes one or more of the following mutations: G237D, P238D, P271G, or A330R.

[0280] In some embodiments, according to the EU numbering scheme, the Fc domain mutation includes one or more of the following mutations: G237D, P238D, D270E, P271G, or A330R. In some embodiments, according to the EU numbering scheme, the Fc domain contains the following mutation set: G237D, P238D, D270E, P271G, and A330R (see, for example, SEQ ID NO: 135, 136, and 163).

[0285] Mutations for heterodimerization In some implementations, an Fc mutation is introduced to promote heterodimerization of two peptides, wherein each peptide contains an Fc domain, and the first and second Fc domains heterodimerize to produce the complete molecule.

[0286] Obtaining heterodimerized Fc domains of two distinct peptides from a single composition is challenging, particularly because random pairing of different peptides can produce undesirable species. Complex purification procedures are required in those cases to isolate the desired antibody agent due to the presence of mismatch byproducts and significantly reduced production yields. Generally, the same problem of mismatch byproducts persists even when recombinant expression techniques are used. One approach to addressing the problem of mismatch byproducts is called the "mortar and pestle structure technique" (KIH), which aims to force pairing of two distinct peptides containing Fc domains by modifying the contact interface by introducing a mutation into the CH3 region of the Fc domain. In one CH3 region, a bulky amino acid is replaced with an amino acid with a short side chain to produce a "mortar," and an amino acid with a large side chain is introduced into the other CH3 region to produce a "pestle." For example, co-expressing the two heavy chains of an antibody with this modification with the two light chains resulted in observed high yields of heterodimer formation compared to homodimers (see Ridgway et al.). Protein Eng.9:617 (1996); and WO 1996 / 027011, which is incorporated herein by reference. In some embodiments, the molecules described herein utilize KIH technology as described, for example, WO 1998 / 050431 (which is incorporated herein by reference in its entirety).

[0287] As described herein, the molecule comprises a first Fc domain and a second Fc domain. In some embodiments, the first Fc domain and / or the second Fc domain comprises CH2 variants and / or CH3 variants, wherein each of such variants independently comprises at least one different amino acid substitution, resulting in heterodimeric domain pairs, such that heterodimerization of the first and second Fc domains of the molecule of the present invention is preferred over homodimerization.

[0288] As described herein, the first and / or second Fc domains in the molecule may contain certain mutations utilizing KIH technology, including but not limited to CH3 modification. In some embodiments, the molecule contains first and second Fc domains modified using a kidney-and-honeypot (KIH) structure to form a heterodimer. In some embodiments, according to the EU numbering scheme, the KIH mutations include Y349T and T394F. In some embodiments, the first Fc domain contains the Y349T mutation, and the second Fc domain contains the T394F mutation. In some embodiments, the first Fc domain contains the T394F mutation, and the second Fc domain contains the Y349T mutation. In some embodiments, according to the EU numbering scheme, the KIH mutations include T366W, S354C, T366S, L368A, Y407V, and Y349C. In some embodiments, the first Fc domain contains the T366W and S354C mutations, and the second Fc domain contains the T366S, L368A, Y407V, and Y349C mutations.

[0292] connector The molecules described herein include an Fc domain linked to an autoantibody-binding domain. In some embodiments, the autoantibody-binding domain is directly linked to the Fc domain. In some embodiments, the autoantibody-binding domain is linked to the Fc domain via a linker. Various linkers are intended for use in the molecules described herein. While linkers may be located between the autoantibody-binding domain and the Fc domain, they may also be located between other domains of the molecule, such as linking one or more self-antigen domains within the autoantibody-binding domain.

[0293] In some embodiments, the linker includes a flexible linker to provide flexibility within the molecule (e.g., between the self-antigen domain and the Fc domain). In some embodiments, the flexible linker contains at least one flexible amino acid (e.g., Gly).

Glycine and glycine-serine polymers are relatively unstructured and therefore may be able to act as neutral linkers between components. Glycine even gains significantly more phi-psi space than alanine and is much less restricted than residues with longer side chains (see Scheraga, where n is an integer of at least 1), glycine-alanine polymers, alanine-serine polymers, and other flexible linkers known in the art. Rev. Computational Chem. 11:173-142 (1992)). In some embodiments, the adapter comprises the amino acid sequence of SEQ ID NO: 150 (GGGGS), SEQ ID NO: 151 (GGGGSGGGGS), SEQ ID NO: 152 (GGGGSGGGGSGGGGS) or SEQ ID NO: 153 (VDGGGGSGGGGSGGGGSG).
