[0001] This Application claims the benefit of U.S. Provisional Application No. 63 / 659,671, filed on June 13, 2024. The entire teachings of the above applications are incorporated herein by reference.INCORPORATION BY REFERENCE OF MATERIAL IN XML
[0002] This application incorporates by reference the Sequence Listing contained in the following extensible Markup Language (XML) file being submitted concurrently herewith: a) File name: 57081079-002 Sequence Listing.xml; created June 13, 2025, 199,625 Bytes in size.BACKGROUND
[0003] The interleukin 4 (IL-4) / interleukin 13 (IL-13) axis has been implicated in numerous inflammatory conditions, including asthma, eczema (atopic dermatitis), food allergy, prurigo nodularis, chronic rhinosinusitis with nasal polyps, keloids, eosinophilic esophagitis, prostate cancer, chronic urticaria, bullous pemphigoid, localized scleroderma, alopecia areata, ulcerative colitis, aspirin-exacerbated respiratory disease, metastatic nonsmall cell lung cancer, and Netherton syndrome. According to the World Health Organization, in 2019 alone, an estimated 262 million people globally were affected by asthma, resulting in 455,000 deaths.
[0004] IL-4 receptor subunit alpha (TL-4Ru) mediates the activity of TL-4 and TL-13, two key proximal type 2 cytokines involved in type 2 immunity against mucosal pathogens and allergens (Gandhi et al., Targeting key proximal drivers of type 2 inflammation in disease, Nat. Rev. Drug Discov. 15:35-50 (2016)). Despite development of candidate anti-IL-4Ra therapies, only one has been FDA-approved. Accordingly, a widespread need exists for additional therapeutics that can target the IL-4Ra-mediated pathogenic pathways driving many immunological / inflammatory diseases (Nur Husna et al., IL-4 / IL-13 axis as therapeutic targets in allergic rhinitis and asthma, PeerJ. 10: 13444 (2022); Shi et al., Involvement oflL- 4, IL-13 and Their Receptors in Pancreatic Cancer, Int.

[0062] A description of example embodiments follows.
[0063] Several aspects of the disclosure are described below, with reference to examples for illustrative purposes only. It should be understood that numerous specific details, relationships, and methods are set forth to provide a full understanding of the disclosure. One having ordinary skill in the relevant art, however, will readily recognize that the disclosure can be practiced without one or more of the specific details or practiced with other methods,protocols, reagents, cell lines and animals. The disclosure is not limited by the illustrated ordering of acts or events, as some acts may occur in different orders and / or concurrently with other acts or events. Furthermore, not all illustrated acts, steps or events are required to implement a methodology in accordance with the disclosure.Definitions
[0064] Unless otherwise defined, all terms of art, notations and other scientific terms or terminology used herein are intended to have the meanings commonly understood by those of skill in the art to which this disclosure pertains. In some cases, terms with commonly understood meanings are defined herein for clarity and / or for ready reference, and the inclusion of such definitions herein should not necessarily be construed to represent a substantial difference over what is generally understood in the art. It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the relevant art and / or as otherwise defined herein.
[0065] The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting.
[0066] When introducing elements disclosed herein, the articles “a,” “an,” “the,” and “said” are intended to mean that there are one or more of the elements. Further, the one or more elements may be the same or different. For example, unless the context clearly indicates otherwise, “a polypeptide” includes a single polypeptide, and two or more polypeptides.
[0067] Throughout this specification and the claims which follow, unless the context requires otherwise, the term “comprise,” and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of, e.g., a stated integer or step or group of integers or steps, but not the exclusion of any other integer or step or group of integer or step. When used herein, the term “comprising” can be substituted with the term “containing” or “including.”
[0068] As used herein, the term “consisting of’ excludes any element, step, or ingredient not specified in the claim element. When used herein, the term “consisting essentially of’ does not exclude materials or steps that do not materially affect the basic and novel characteristics of the claim.
[0069] Any of the terms “comprising,” “containing,” “including,” and “having,” whenever used herein in the context of an aspect or embodiment disclosed herein, can insome embodiments, be replaced with the term “consisting of,” or “consisting essentially of’ to vary scopes disclosed herein.
[0070] As used herein, the conjunctive term “and / or” between multiple recited elements is understood as encompassing both individual and combined options. For instance, where two elements are conjoined by “and / or,” a first option refers to the applicability of the first element without the second. A second option refers to the applicability of the second element without the first. A third option refers to the applicability of the first and second elements together. Any one of these options is understood to fall within the meaning, and, therefore, satisfy the requirement of the term “and / or” as used herein. Concurrent applicability of more than one of the options is also understood to fall within the meaning, and, therefore, satisfy the requirement of the term “and / or.”
[0071] It should be understood that for all numerical bounds describing some parameter in this application, such as “about,” “at least,” “less than,” “fewer than,” and “more than,” the description also necessarily encompasses any range bounded by the recited values. Accordingly, for example, the description “at least 1, 2, 3, 4, or 5” also describes, inter alia, the ranges 1-2, 1-3, 1-4, 1-5, 2-3, 2-4, 2-5, 3-4, 3-5, and 4-5, et cetera.
[0072] When a list is presented, unless stated otherwise, it is to be understood that each individual element of that list, and every combination of that list, is a separate embodiment. For example, a list of embodiments presented as “A, B, or C” is to be interpreted as including the embodiments, “A,” “B,” “C,” “A or B,” “A or C,” “B or C,” or “A, B, or C .”
[0073] As used herein, the term “about” means within an acceptable error range for a particular value, as determined by one of ordinary skill in the art. Typically, an acceptable error range for a particular value depends, at least in part, on how the value is measured or determined, e.g., the limitations of the measurement system. For example, “about” can mean within an acceptable standard deviation, per the practice in the art. Alternatively, “about” can mean a range of ± 20%, e.g., ± 10%, ± 5% or ± 1% of a given value. It is to be understood that the term “about” can precede any particular value specified herein, except for particular values used in the Exemplification. When “about” precedes a range, as in “90-99.9%,” the term “about” should be read as applying to both given values of the range, such that “about 90-99.9%” means about 90% to about 99.9%.
[0074] As used herein, the term “polypeptide” refers to a polymer of at least two amino acids covalently linked by an amide bond, regardless of length or post-translational modification (e.g., glycosylation or phosphorylation). A polypeptide can comprise anysuitable L-and / or D-amino acid, for example, common a-amino acids (e.g., alanine, glycine, valine), non-a-amino acids (e.g., [3-alanine, 4-aminobutyric acid, 6-aminocaproic acid, sarcosine, statine), and unusual amino acids (e.g., citrulline, homocitruline, homoserine, norleucine, norvaline, ornithine). The amino, carboxyl, and / or other functional groups on a polypeptide can be free (e.g., unmodified) or protected with a suitable protecting group. Suitable protecting groups for amino and carboxyl groups, and methods for adding or removing protecting groups are known in the art and are disclosed in, for example, Green and Wuts, “Protecting Groups in Organic Synthesis, ” John Wiley and Sons, 1991. The functional groups of a polypeptide can also be derivatized (e.g., alkylated) or labeled (e.g., with a detectable label, such as a fluorogen or a hapten) using methods known in the art. A polypeptide can comprise one or more modifications (e.g., amino acid linkers, acylation, acetylation, amidation, methylation, terminal modifiers (e.g., cyclizing modifications), N- methyl-a-amino group substitution), if desired. In addition, a polypeptide can be an analog of a known and / or naturally-occurring peptide, for example, a peptide analog having conservative amino acid residue substitution(s). The terms “polypeptide” and “protein” are used interchangeably herein.
[0075] As used herein, a “polynucleotide” is defined as a plurality of nucleotides and / or nucleotide analogs linked together in a single molecule. In some embodiments, a polynucleotide disclosed herein comprises deoxyribonucleotides. In some embodiments, the polynucleotide comprises ribonucleotides. Non-limiting examples of polynucleotides include single-, double- or multi -stranded DNA or RNA, DNA-RNA hybrids (e.g., each “T” position may be independently substituted by a “U” or vice versa), or a polymer comprising purine and pyrimidine bases, or other natural, chemically, or biochemically modified, non-natural, or derivatized nucleotide bases. The backbone of the polynucleotide can comprise sugars and phosphate groups, modified or substituted sugar or phosphate groups, a polymer of synthetic subunits such as phosphoramidates, or a combination thereof.
[0076] As used herein, the term “sequence identity” refers to the extent to which two nucleotide sequences have the same residues at the same positions when the sequences are aligned to achieve a maximal level of identity, expressed as a percentage. For sequence alignment and comparison, typically one sequence is designated as a reference sequence, to which test sequences are compared. Sequence identity between reference and test sequences is expressed as a percentage of positions across the entire length of the reference sequence where the reference and test sequences share the same nucleotide or amino acid uponalignment of the reference and test sequences to achieve a maximal level of identity. As an example, two sequences are considered to have 70% sequence identity when, upon alignment to achieve a maximal level of identity, the test sequence has the same nucleotide residue at 70% of the same positions over the entire length of the reference sequence.
[0077] Alignment of sequences for comparison to achieve maximal levels of identity can be readily performed by a person of ordinary skill in the art using an appropriate alignment method or algorithm. In some instances, alignment can include introduced gaps to provide for the maximal level of identity. Examples include the local homology algorithm of Smith & Waterman, Adv. AppL Math. 2:482 (1981), the homology alignment algorithm of Needleman & Wunsch, J. Mol. Biol. 48:443 (1970), the search for similarity method of Pearson & Lipman, Proc. Nat’L Acad. Sci. USA 85:2444 (1988), computerized implementations of these algorithms (GAP, BESTFIT, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Genetics Computer Group, 575 Science Dr., Madison, Wis.), and visual inspection (see generally Ausubel et al., Current Protocols in Molecular Biology).
[0078] When using a sequence comparison algorithm, test and reference sequences are input into a computer, subsequent coordinates are designated, if necessary, and sequence algorithm program parameters are designated. The sequence comparison algorithm then calculates the percent sequence identity for the test sequence(s) relative to the reference sequence, based on the designated program parameters. A commonly used tool for determining percent sequence identity is Protein Basic Local Alignment Search Tool (BLASTP) available through National Center for Biotechnology Information, National Library of Medicine, of the United States National Institutes of Health (Altschul etal., 1990).
[0079] As used herein, the term “substantially similar to” refers to a polypeptide disclosed herein that is substantially similar in amino acid sequence (e.g., has at least about 80%, at least about 90%, at least about 95%, at least about 96%, at least about 97%, at least about 98%, or at least about 99% of the amino acid residues amino acid sequence identity) and substantially preserves one or more functional properties of a specified polypeptide disclosed herein. In some embodiments, the one or more functional properties are selected from, without limitation, a substantially similar binding affinity, a substantially similar binding specificity, a substantially similar inhibitory activity, a substantially similar neutralization activity, and a substantially similar self-association property.
[0080] As used herein, a “complementarity determining region (CDR)” encompasses any CDR defined by an art-recognized method for identifying the CDR residues on an antibody.See, e.g., Kabat, E.A., et aL, (1991) Sequences of Proteins of Immunological Interest, Fifth Edition, U.S. Department of Health and Human Services, NIH Publication No. 91-3242, Chothia et al., (1989) Nature 342:877; Chothia, C. et al., (1987) J. Mol. Biol. 196:901-917; Al-lazikani et al., (1997) J. Molec. Biol. 273:927-948; and Almagro, J. Mol. Recognit. 17: 132-143 (2004). See also hgmp.mrc.ac.uk and bioinf.org.uk / abs. Two antibodies are determined to have the same CDR as one another with respect to a HCDR1, HCDR2, HCDR3, LCDR1, LCDR2 and / or LCDR3, when the identity of that CDR is determined for both antibodies using the same method.
[0081] The extent of the framework region and the CDRs of an antibody can be identified using one of several suitable methodologies that are well known in the art, for example, by the Kabat definition, the Chothia definition, the AbM definition, and / or the contact definition. Publicly and / or commercially available tools for identifying framework and / or CDR regions include, IgBlast (accessible at www.ncbi.nlm.nih.gov / igblast / ), Scaligner (available from drugdesigntech at www.scaligner.com / ), IMGT rules and / or tools (see, for example, www.imgt.org / IMGTScientificChart / Nomenclature / IMGT-FRCDRdefmition.html, also accessible at www.imgt.org / ), Chothia Canonical Assignment (accessible at www.bioinf.org.uk / abs / chothia.html), Antigen receptor Numbering And Receptor Calssificatilon (ANARCI, accessible at opig.stats.ox.ac.uk / webapps / newsabdab / sabpred / anarci / ), or see Vered Kunik, et al, Nucleic Acids Research, Volume 40, Issue Wl, 1 July 2012, Pages W521-W524).

The term “treating,” or “treatment” refers to the medical management of a subject with the intent to improve, ameliorate, stabilize (i.e., not worsen), prevent, or cure a disease, pathological condition, or disorder — such as the particular indications exemplified herein. This term includes active treatment (treatment directed to improve the disease, pathological condition, or disorder), causal treatment (treatment directed to the cause of the associated disease, pathological condition, or disorder), palliative treatment (treatment designed for the relief of symptoms), preventative treatment (treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder); and supportive treatment (treatment employed to supplement another therapy). Treatment also includes diminishment of the extent of the disease or condition; preventing spread of the disease or condition; delay or slowing the progress of the disease or condition;amelioration or palliation of the disease or condition; and remission (whether partial or total), whether detectable or undetectable. “Ameliorating” or “palliating” a disease or condition means that the extent and / or undesirable clinical manifestations of the disease, disorder, or condition are lessened and / or time course of the progression is slowed or lengthened, as compared to the extent or time course in the absence of treatment. “Treatment” can also mean prolonging survival as compared to expected survival if not receiving treatment. Those in need of treatment include those already with the condition or disorder, as well as those prone to have the condition or disorder or those in which the condition or disorder is to be prevented.
[0091] A “pharmaceutical composition” refers to a formulation of one or more therapeutic agents and a medium generally accepted in the art for delivery of a biologically active agent to subjects, e.g., humans.

[0321] In some embodiments, a polypeptide has a weaker self-association than the Reference Antibody, for example, as determined by an affinity-capture self-interaction nanoparticle spectroscopy (AC-SINS) value. The AC-SINS value is the change in maximum absorbance wavelength in the coated-nanoparticle absorption spectra compared to the spectra of the nanoparticle alone. Thus, the greater the change in maximum absorbance wavelength, the more self-interaction of the antibody coated on the nanoparticle. Self-association is an unwanted property that correlates with poor viscosity and poor PK properties. Techniques and assays for assessing self-association of proteins are known in the art. See, e.g., Patro &Przybycien, Biotechnol Bioeng. 52(2): 193-203 (1996), the contents of which are incorporated herein in their entirety.

In some embodiments, a polypeptide has an AC-SINS value of about 13-14, 13-15, 7-9 or 7-8. In some embodiments, a polypeptide has an AC- SINS value of about: 8 or 14.
[0323] In some embodiments, a polypeptide has an improved developability (e.g., reduced AC-SINS) relative to the Reference Antibody.

[0325] In some embodiments, the self-association of a polypeptide is about 1-90% relative to that of the Reference Antibody, for example, about: 2-90%, 2-85%, 3-85%, 3- 80%, 4-80%, 4-75%, 5-75%, 5-70%, 6-70%, 6-65%, 7-65%, 7-60%, 8-60%, 8-55%, 9-55%, 9-50%, 10-50%, 10-45%, 15-45%, 15-40%, 20-40%, 20-35%, 25-35% or 25-30%, relative to that of the Reference Antibody.

[0347] The term “subject” and “patient” are used herein interchangeably to refer to an animal (e.g., a mammal, such as a human) who is to be treated according to a method disclosed herein. A subject to be treated according to methods described herein may be one who has been diagnosed with a particular condition (e.g., in inflammatory condition), or one at risk of developing such conditions or symptoms of such conditions. Diagnosis may be performed by any method or technique known in the art. One skilled in the art willunderstand that a subject to be treated according to the present disclosure may have been subjected to standard tests or may have been identified, without examination, as one at risk due to the presence of one or more risk factors associated with the disease or condition.
[0348] In some embodiments, the subject has (e.g., confirmed by testing), or is suspected of having, an inflammatory condition. In some embodiments, the subject has an inflammatory condition. In some embodiments, the subject has been diagnosed with an inflammatory condition. In some embodiments, the subject is at risk of developing an inflammatory condition.
[0349] In some embodiments, the subject is a mammal. In some embodiments, the subject is a mammal selected from the group consisting of a dog, a cat, a mouse, a rat, a hamster, a guinea pig, a horse, a pig, a sheep, a cow, a chimpanzee, a macaque, a cynomolgus, and a human.

[0353] “A therapeutically effective amount,” “an effective amount” or “an effective dosage” is an amount effective, at dosages and for periods of time necessary, to achieve a desired therapeutic result (e.g., treatment, healing, inhibition or amelioration of physiological response or condition, etc.). The therapeutic effect does not necessarily occur by administration of one dose, and may occur only after administration of a series of doses.Thus, a therapeutically effective amount may be administered in one or more administrations. A therapeutically effective amount may vary according to factors such as disease state, age, sex, and weight of a mammal, mode of administration and the ability of a therapeutic, or combination of therapeutics, to elicit a desired response in an individual.
[0354] An effective amount of an agent to be administered can be determined by a clinician of ordinary skill using the guidance provided herein and other methods known in theart. Relevant factors include the given agent, the pharmaceutical formulation, the route of administration, the type of disease or disorder, the identity of the subject (e.g., age, sex, weight) or host being treated, and the like. For example, suitable dosages can be from about 0.001 mg / kg to about 100 mg / kg, from about 0.01 mg / kg to about 100 mg / kg, from about 0.01 mg / kg to about 10 mg / kg, from about 0.01 mg / kg to about 1 mg / kg body weight per treatment. Determining the dosage for a particular agent, subject and disease is well within the abilities of one of skill in the art. Preferably, the dosage does not cause or produces minimal adverse side effects.
[0355] Desired response or desired results include effects at the cellular level, tissue level, or clinical results. As such, “a therapeutically effective amount” or synonym thereto depends upon the context in which it is being applied. For example, in some embodiments it is an amount of the composition sufficient to achieve a treatment response as compared to the response obtained without administration of the composition. In some embodiments, it is an amount that results in a beneficial or desired result in a subject as compared to a control. As defined herein, a therapeutically effective amount of a composition disclosed herein may be readily determined by one of ordinary skill by routine methods known in the art. Dosage regimen and route of administration may be adjusted to provide the optimum therapeutic response.
[0356] In some embodiments, methods disclosed herein are used for prophylactic therapy. In some embodiments, the effective dosage is sufficient to prevent the subject from experiencing symptoms of an inflammatory condition.
[0357] In some embodiments, methods disclosed herein are used for treating an inflammatory condition e.g., atopic dermatitis).
[0358] The term “treating” or “treatment” refers to the medical management of a subject with the intent to improve, ameliorate, stabilize (i.e., not worsen), prevent or cure a disease, pathological condition, or disorder — such as the particular indications exemplified herein. This term includes active treatment (treatment directed to improve the disease, pathological condition, or disorder), causal treatment (treatment directed to the cause of the associated disease, pathological condition, or disorder), palliative treatment (treatment designed for the relief of symptoms), preventative treatment (treatment directed to minimizing or partially or completely inhibiting the development of the associated disease, pathological condition, or disorder); and supportive treatment (treatment employed to supplement another therapy). Treatment also includes diminishment of the extent of the disease or condition; preventingspread of the disease or condition; delay or slowing the progress of the disease or condition; amelioration or palliation of the disease or condition; and remission (whether partial or total), whether detectable or undetectable. “Ameliorating” or “palliating” a disease or condition means that the extent and / or undesirable clinical manifestations of the disease, disorder, or condition are lessened and / or time course of the progression is slowed or lengthened, as compared to the extent or time course in the absence of treatment. “Treatment” can also mean prolonging survival as compared to expected survival if not receiving treatment. Those in need of treatment include those already with the condition or disorder, as well as those prone to have the condition or disorder or those in which the condition or disorder is to be prevented.
[0359] In some embodiments, the effective dosage is sufficient to reduce IL-4 / IL-13 signaling in the subject. In some embodiments, the reduction in IL-4 / IL-13 signaling is by at least about 10%, e.g., by at least about: 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99%. In some embodiments, the reduction in viral load is about 10-99%, e.g., about: 10-98%, 15-98%, 15-97%, 20-97%, 20-96%, 25-96%, 25-95%, 30-95%, 30-94%, 35-94%, 35-93%, 40-93%, 40-92%, 45-92%, 45-91%, 50-91%, 50-90%, 55-90%, 55-85%, 60-85%, 60-80%, 65-80%, 65-75%, or 70-75%.
[0360] In some embodiments, the effective dosage is sufficient to inhibit binding of IL-4 or IL- 13 to IL-4Ra, target cells, or both. In some embodiments, the reduction in binding is by at least about 10%, e.g., by at least about: 15%, 20%, 25%, 30%, 35%, 40%, 45%, 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90%, 91%, 92%, 93%, 94%, 95%, 96%, 97%, 98% or 99%. In some embodiments, the reduction in binding is about 10-99%, e.g., about: 10-98%, 15-98%, 15-97%, 20-97%, 20-96%, 25-96%, 25-95%, 30-95%, 30-94%, 35-94%, 35-93%, 40-93%, 40-92%, 45-92%, 45-91%, 50-91%, 50-90%, 55-90%, 55-85%, 60-85%, 60-80%, 65-80%, 65-75%, or 70-75%.

[0372] Preferred features of each of the aspects or embodiments provided by the invention are applicable to all of the other aspects or embodiments of the invention mutatis mutandis and, without limitation, are exemplified by the dependent claims and also encompass combinations and permutations of individual features (e.g., elements, including numerical ranges and exemplary embodiments) of particular embodiments and aspects of the invention, including the working examples. For example, particular experimental parameters exemplified in the working examples can be adapted for use in the claimed invention piecemeal without departing from the invention. For example, for materials that are disclosed, while specific reference of each of the various individual and collectivecombinations and permutations of these compounds may not be explicitly disclosed, each is specifically contemplated and described herein. Thus, if a class of elements A, B, and C are disclosed as well as a class of elements D, E, and F and an example of a combination of elements A-D is disclosed, then, even if each is not individually recited, each is individually and collectively contemplated. Thus, in this example, each of the combinations A-E, A-F, B- D, B-E, B-F, C-D, C-E, and C-F are specifically contemplated and should be considered disclosed from disclosure of A, B, and C; D, E, and F; and the example combination A-D. Likewise, any subset or combination of these is also specifically contemplated and disclosed. Thus, for example, the sub-groups of A-E, B-F, and C-E are specifically contemplated and should be considered disclosed from disclosure of A, B, and C; D, E, and F; and the example combination A-D. This concept applies to all aspects of this application, including elements of a composition of matter and steps of method of making or using the compositions.

[0374] Applicant, through computational design and experimental validation, has facilitated an understanding of structure and function interrelation of anti-IL-4Ra antibodies and herein provides the skilled artisan the means to use such understanding. For example, the Application provides Computer Program Listing Appendices (also referred to herein as Appendices A, B, and C, respectively) that can be used to both evaluate (score) a given sequence or generate a sequence having a score that, when evaluated, is above a given threshold. These Appendices include a Potts model of polypeptides provided by embodiments.
[0375] A statistical machine learning model, according to some embodiments, was developed to predict functional properties of polypeptides, e.g., antibody binding to an interleukin-4 receptor alpha (IL-4Ra) target. An example model was trained on experimental binding data and uses a Potts statistical model to make predictions about, e.g., whether novel antibody sequences will bind to IL-4Ra.
[0376] For model selection, multiple example candidate model architectures were evaluated as described below, and a Potts model was selected based on optimal performance across multiple metrics: a) Linear model (224 parameters) b) Uniform model (224 parameters) c) Positive Potts model (169,408 parameters) d) Mixture model (231,492 parameters) e) Joint model (246,717 parameters) f) Ratio model (383,128 parameters)
[0377] The selected Potts model, according to some embodiments, demonstrates strong predictive performance according to the following example model performance metrics: a) Area Under Curve (probability of distinguishing one randomly selected positive instance from one randomly selected negative instance): 0.831 b) Accuracy: 76.2% c) Precision (true positives / (true positives + false positives)): 60.5% d) Recall (true positives / (true positives + false negatives)): 84.3% e) Fl Score (harmonic mean of precision and recall): 0.704 [2 * ((0.605 * 0.843) / (0.605 + 0.843)) = -0.704]f) Binding Threshold: -27.87 (model score)
[0378] In some embodiments, the model may utilize an example dataset that is sourced from experimental binding affinity data from antibody variants for a target of interleukin-4 receptor alpha (IL-4Ra). The dataset may include 378 example antibody sequences with binding affinities measured to determine binding dissociation constants (KD values). An example binding threshold of log(Ko) = 0.375 may be established, z.e., sequences with log(Ko) < 0.375 may be classified as “binding.” Other binding threshold values are also suitable.
[0379] The model architecture may be a positive Potts model that employes a statistical physics-based approach for sequence modeling. 169,408 example model parameters may be used. The model may take as input variable regions from heavy chain (VH) and light chain (VL) antibody sequences. An example VH region input may include 25 amino acid positions, while an example VL region input may include 17 amino acid positions, resulting in a total of 42 example amino acid positions for analysis.
[0380] In some embodiments, for a statistical approach, the model may leverage a Potts statistical framework that analyzes single amino acid site effects. For example, the framework may capture a preference for specific amino acids at each amino acid position in a given sequence of a polypeptide. The framework may further analyze pairwise interactions between amino acids at different positions. For example, the framework may model epistatic effects between amino acid positions. The framework may further perform cross-entropy scoring. For example, the framework may use negative log-pseudolikelihood for sequence evaluation.
[0381] In certain embodiments, the model may utilize a scoring mechanism where higher scores indicate, e.g., a greater likelihood of binding. According to an embodiment, a threshold value of approximately -27.87 for negative log-pseudolikelihood may separate, e.g., binding from non-binding sequences. Other threshold values may also be used. As described herein, a scoring mechanism according to some embodiments may incorporate both individual amino acid preferences and inter-position correlations.
[0382] It should be noted that in certain embodiments, a Potts model may not directly predict KD or log(Ko) values, but rather may generate a score (e.g., a negative log- pseudolikelihood) that correlates with KD or log(Ko) values. According to some embodiments, a threshold for a Potts model score may be specified so as to maximally correctly classify a set of binders (e.g., log(Ko) < 0.375) from nonbinders (e.g., log(Ko) >=0.375) using training data. In certain embodiments, a threshold for a Potts model score may correspond either exactly or approximately to a log(Ko) value of 0.375.
[0383] The Computer Program Listing Appendices are referred to as Appendix A (score_concise.txt), Appendix B (score.txt), and Appendix C (fit_model.txt), which are herein incorporated by reference in their entireties. A person having ordinary skill in the art can recognize that Appendix A or Appendix B can respectively be renamed “score concise.py” or “score. py” to be executed using standard libraries (e.g., math, sys, etc.) and without external dependencies in a Python environment (e.g., Python 3.x), compiler, or other equivalent environment that can run Python scripts, and that Appendix C can be renamed “fit model.etab” and can be loaded by the script of Appendix A or Appendix B. A person having ordinary skill in the art can recognize that, in some embodiments, a Python environment may also run or compile the script of Appendix A or Appendix B without renaming. Other known programming languages and / or scripting environments are also suitable. When running the score_concise . py or score . py file, two sequences (or one combined sequence) can be inputted. In embodiments, the below description further describes the scripts of Appendices A and B and the model file of Appendix C.
[0384] The Potts model may be represented by a table of trained model parameters. The table may include single amino acid site parameters and pairwise amino acid parameters. For the single site parameters, the table may include a position of a residue (e.g., amino acid), the residue, and a value (e.g., a floating-point value) associated with the residue at that position. For the pairwise parameters, the table may include two positions, two residues, and a value (e.g., a floating-point value) associated with the two residues at the respective positions. The model parameters may be stored in the plaintext model file f it_model . etab.
[0385] In some embodiments, a script (e.g., Appendix A or Appendix B) may be employed to determine whether a sequence pair (e.g., VH and VL — although, for clarity, the sequence pair, in different embodiments, can be separate polypeptide chains or, in some embodiments, a single polypeptide chain, e.g., an scFV) is claimed under the model — z.e., whether the sequence pair, when scored by the model, is above a threshold. The script may be referred to as a computationally binding optimized (CBO) script. The script may take full- length sequences as inputs, e.g., VH and VL sequences provided as complete antibody sequences. In an embodiment, the sequences may be in standard single-letter amino acid code format; other known formats are also suitable. To continue, the script may then confirm thatthe input sequences match specific constant region templates. Shown below are example sequence templates according to an embodiment:Heavy Chain TemplateEVQLVESGGGLEQPGGSLRLSCAGSGXXXXXXAMTWVRQAPGKGLEWVSSIXGSGXXXYYADSVKGRFTISRDNS KNTLYLQMNSLRAEDTAVYYCXXXXXXXXXXPXYXGXXXWGQGTTVTVSSLight Chain TemplateDIVMTQSPLSLPVTPGEPASISCRSSXSXXYXXGXXYLDWYLQKSGQSPQLLIYXXXNRASGVPDRFSGSGSGTD FTLKI SRVEAEDVGFYYCXXXXXXPXTFGQGTKLE I K where 'X' denotes variable positions that are analyzed by the model.
[0386] In certain embodiments, a script, e.g., score_concise . py (Appendix A), may be used in either manner shown below:Command Line Usage python score_concise . py "VH_SEQUENCE" "VL_SEQUENCE"Python Application Programming Interface (API) Usage from score_concise import is_binding_antibody# Returns True if predicted to bind, False otherwise result = is_binding_antibody (vh_sequence , vl_sequence)
[0387] The script may construct two parameter hash tables for single site parameters and pairwise parameters, respectively, by loading an existing model file (e.g., Appendix C) and extracting single site amino acid positions / amino acid position pairs, amino acid identifiers, and corresponding values for each. For the single site parameters table, the script may extract one position, one residue identifier, and one value associated with the residue at the position. For the pairwise parameters table, the script may extract a first position, a second position, a first residue identifier, a second residue identifier, and a value associated with the first residue at the first position and the second residue at the second position.
[0388] The two sequences, the VH sequence and VL sequence, input to the script may then be aligned. The alignment may confirm that the VH sequence and VL sequence are the same length as template sequence(s) and that given sections of both input sequences are the same as the template sequence(s). Once confirmed, residues from both input sequences at specified positions may then be extracted to form a trimmed and concatenated sequence. Inturn, a sequence score may be determined for the given concatenated sequence using the two parameter hash tables.
[0389] The following steps describe some embodiments of determining the sequence score. The is_binding_antibody ( ) function of the script of Appendix A may call the calculate_binding_score ( ) function to determine and return a score for the sequence. The return value of the calculate_binding_score ( ) function may represent a sum of cross-entropy loss at each amino acid position in the concatenated sequence. If the sequence score is greater than the threshold, which in some embodiments is approximately -27.87, then the sequences meet the required parameters (e.g., are confirmed / verified by the Potts model) and the is_binding_antibody ( ) function may return true. Otherwise, the function may return false and the sequence pair is not confirmed by the model. When the is_binding_antibody ( ) function returns true, this may indicate that the sequence pair is suitable for the given purpose (e.g., a purpose related to binding to human IL-4Ra).
[0390] In some embodiments, the script of Appendix A may define a sequence scoring function (calculate_binding_score) that takes as inputs a sequence and a pair of parameter hash tables constructed from a model file (e.g., Appendix C). This function may determine a plurality of energy scores, including single amino acid energy scores and pairwise amino acid energy scores, for each amino acid position in the sequence. For a given amino acid position in the sequence, the calculate_binding_score function may use a Potts model to determine a single amino acid energy score and a sum of pairwise amino acid energy scores for each possible residue (e.g., amino acid) at the position. As described above, the function may check each possible residue at each position requested. A person of ordinary skill in the art can recognize that the script can replace residues at each given position (as in the script of Appendix A). In some embodiments, a similar script could add residues into the sequence. Continuing with the calculate_binding_score function, the single amino acid energy score and the sum of pairwise amino acid energy scores may be summed and added to an array of amino acid energies. A maximum energy value in the array of amino acid energies may then be determined and the array may be further used to generate a partition function. In some embodiments, a “softmax” function or “LogSumExp” (also called “RealSoftMax”) function may be applied to normalize the amino acid energies for numerical stability; other known normalization techniques are also suitable. A cross-entropymetric e.g., cross-entropy loss) may be determined for the given amino acid position based on an amino acid at the amino acid position, the maximum energy value, and the partition function. Other known metrics are also suitable. In turn, the calculate_binding_score function may sum the cross-entropy metrics at each amino acid position and use the resulting sum to generate a sequence score, which score may be returned by the function.
[0391] In some embodiments, the script of Appendix A may define a load_model_parameters ( ) function to load Potts model parameters from a model file (e.g., Appendix C). The file may be a f it_model . etab file in plaintext “.etab” format; other model file formats are also suitable, including text-based and binary formats, for nonlimiting examples. To continue, each line in the file having three items may be unpacked by the load_model_parameters ( ) function and converted into an entry in a first hash table for single amino acid site parameters. Each line in the file having five items may be unpacked and converted into an entry of a second hash table for pairwise amino acid parameters. The two hash tables may then be returned by the load_model_parameters ( ) function.
[0392] The above steps and functions relate to examples of a “computationally binding optimized” (CBO) sequence, amino acid sequence, or polypeptide sequence. Such a sequence is a sequence that, when inputted into the above CBO script of Appendix A, returns a value of true. A person having ordinary skill in the art can recognize that the script can be implemented in other ways and / or with other series of steps, e.g., in the form of the script of Appendix B. A person having ordinary skill in the art can also recognize that other functionally equivalent tables can be used in place of the table of Appendix C. However, the provided Python scripts and table, when executed by a processor, are configured to output whether a given polypeptide sequence is a CBO sequence. Therefore, any sequence that, when analyzed by the scripts, results in a Boolean “true” output, is considered a CBO sequence. Any sequence that, when run by the scripts, results in a Boolean “false” output, is considered excluded from the group of the CBO sequences. Therefore, in some embodiments, the scripts of Appendix A and Appendix B themselves do not determine CBO sequences, but instead are tools to confirm whether a given sequence is a CBO sequence or not. When a CBO sequence is an amino acid sequence, the corresponding molecule having the amino acid sequence is referred to as a CBO polypeptide.
[0393] In certain embodiments, a similar script to Appendix A or Appendix B can return calculated scores of a given or multiple sequences in addition to or separate from a Boolean value representing the scores exceeding a threshold.
[0394] In some embodiments, a similar script to Appendix A or Appendix B can return one or more generated sequences from a Potts model. To generate sequences, Markov chain Monte Carlo (MCMC) sampling can be performed on the model. The resulting samples can then be reintegrated into a sequence template. In some embodiments, a brute force technique can be applied using the calculate_binding_score function of Appendix A.

[0396] The Potts model, according to some embodiments, was validated using multiple example techniques as described below:a) Threshold optimization'. Youden’s J statistic was used to find an optimal discrimination threshold. b) Cross-validation'. Model performance was assessed on held-out test sequences. c) Template matching'. Templates were utilized to ensure sequence compatibility before prediction.
[0397] Shown below are example validation results for the Potts model according to some embodiments: a) True Positive Rate. 84.3% (correctly identifies binding antibodies) b) False Positive Rate. 27.9% (incorrectly predicts binding for non-binding antibodies) c) True Negative Rate. 72.1% (correctly identifies non-binding antibodies) d) False Negative Rate. 15.7% (incorrectly predicts non-binding for binding antibodies)
[0398] In some embodiments, the scripts of Appendix A and Appendix B may depend on sequence templates by requiring input sequences to match specific constant region templates. The Potts model, according to some embodiments, may have a training data scope based on training the model on specific IL-4Ra binding data without validating generalization to other potential targets. Experimental validation may be performed on computational predictions generated by a model to confirm the predictions with experimental binding assays. The 27.9% false positive rate according to some embodiments discussed herein may indicate that approximately 1 in 4 predicted binders may not actually bind.
[0399] A Potts model according to an embodiment was applied to an example set of 17 test sequences, resulting in 12 of the 17 sequences (approx. 70.6%) being predicted as binding. Table 10 shows the 12 sequences predicted as binding and their corresponding log(Ko) scores.Table 10: Example Variable Sequences and log(Ko) ScoresExample Method Embodiment
[0400] FIG. 10 is a flowchart of a method 1000 for predicting a functional property of a polypeptide according to an embodiment. The method 1000 is computer-implemented and may be implemented using any computing device, e.g., a processor, or combination of computing devices known to those of skill in the art.
[0401] The method 1000 begins at step 1001 by, via a computationally binding optimized (CBO) model, for each amino acid position of an amino acid sequence of the polypeptide: (1) determining a plurality of energy scores based on the amino acid position in the amino acid sequence, (2) generating a partition function based on the plurality of energy scores determined, and (3) determining a cross-entropy metric (e.g., cross-entropy loss) based on (i) an amino acid at the amino acid position in the amino acid sequence, (ii) a maximum energy score of the plurality of energy scores determined, and (iii) the generated partition function. At step 1002, an analysis score of the polypeptide is generated based on each cross-entropy metric determined. The analysis score indicates a predicted functional property of thepolypeptide. The polypeptide comprises an immunoglobulin heavy chain variable domain (VH) comprising an amino acid sequence having at least 90% sequence identity to SEQ ID NO: 18 and an immunoglobulin light chain variable domain (VL) comprising an amino acid sequence having at least 90% sequence identity to SEQ ID NO:37. The polypeptide does not comprise a VH comprising an amino acid sequence having 100% sequence identity to SEQ ID NO: 5 and a VL comprising an amino acid sequence having 100% sequence identity to SEQ ID NO:24.
[0402] In some example embodiments, the polypeptide comprises an immunoglobulin heavy chain variable domain (VH) comprising an amino acid sequence having at least 70% (e.g., at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100%) amino acid sequence identity to SEQ ID NO: 18 and an immunoglobulin light chain variable domain (VL) comprising an amino acid sequence having at least about 70% amino acid sequence identity (e.g., at least 75%, at least 80%, at least 85%, at least 90%, at least 95%, at least 96%, at least 97%, at least 98%, at least 99%, or 100%) amino acid sequence identity to SEQ ID NO:37. In some example embodiments, the polypeptide comprises an immunoglobulin heavy chain variable domain (VH) comprising an amino acid sequence having at least 90% amino acid sequence identity to SEQ ID NO: 18 and an immunoglobulin light chain variable domain (VL) comprising an amino acid sequence having at least 90% amino acid sequence identity to SEQ ID NO:37. In some example embodiments, the polypeptide comprises an immunoglobulin heavy chain variable domain (VH) comprising an amino acid sequence having at least 95% amino acid sequence identity to SEQ ID NO: 18 and an immunoglobulin light chain variable domain (VL) comprising an amino acid sequence having at least 95% amino acid sequence identity to SEQ ID NO:37.

[0406] In an example embodiment of the method 1000, for at least one amino acid position of the amino acid sequence of the polypeptide, generating the partition function at step 1001 may be further based on a softmax function.
[0407] According to an example embodiment of the method 1000, at least one of: (1) predicting the functional property of the polypeptide may be implementable by a script of Appendix A or Appendix B, and (2) the CBO model may be substantially similar to a table of Appendix C.

In such an embodiment, a given polypeptide sequence may be automatically transmitted to a manufacturing device and the manufacturing device may responsively and automatically generate the real-world polypeptide.Computer Support
[0420] FIG. 11 is a schematic view of a computer network in which embodiments may be implemented. Client computer(s) / devices 50 and server computer(s) 60 provide processing, storage, and input / output (I / O) devices executing application programs and the like. Client computer(s) / device(s) 50 can also be linked through communications network 70 to other computing devices, including other client device(s) / processor(s) 50 and server computer(s) 60. The communications network 70 can be part of a remote access network, a global network (e.g., the Internet), cloud computing servers or service, a worldwide collection of computers, local area or wide area networks, and gateways that currently use respective protocols (e.g., TCP / IP, Bluetooth®, etc.) to communicate with one another. Other electronic device / computer network architectures are also suitable.
[0421] FIG. 12 is a block diagram illustrating an example embodiment of a computer node (e.g., client processor(s) / device(s) 50 or server computer(s) 60) in the computer network 70 of FIG. 11. Each computer node 50, 60 contains system bus 79, where a bus is a set of hardware lines used for data transfer among components of a computer or processing system. The system bus 79 is essentially a shared conduit that connects different elements of a computer system (e.g., processor, disk storage, memory, I / O ports, network ports, etc.) that enables transfer of information between the elements. Attached to the system bus 79 is an I / O devices interface 82 for connecting various input and output devices (e.g., keyboard, mouse, display(s), printer(s), speaker(s), etc.) to the computer node 50, 60. A network interface 86 allows the computer node to connect to various other devices attached to a network (e.g., the network 70 of FIG. 11). A memory 90 provides volatile storage for computer software instructions 92a and data 94a used to implement some embodiments of the present disclosure(e.g., the method 1000 of FIG. 10, etc.).

Generation and Characterization of IL-4Ra-Binding Polypeptides (Overview)Diversity Generation Campaign
[0430] The diversity generation campaign chose a human anti-IL-4Ra antibody as a Reference Antibody (“Reference”). A variant set of 384 antibodies was generated, and data on target binding (surface plasmon resonance or “SPR”) was acquired. A subset of 205 target-binding antibodies was selected and tested for developability and function. Two of the 205 target-binding antibodies bound IL-4Ra with high affinity and were selected as seeds for the co-optimization campaign.Co-Optimization Campaign
[0431] Using seeds from the diversity generation campaign, a second variant set of 384 antibodies was generated in the project learning and co-optimization campaign, and data on target binding was acquired. A subset of 163 target-binding antibodies was selected and tested for developability and function. Developability and function data were combined to identify 20 screening hits with acceptable developability parameters (Affinity-Capture SelfInteraction Nanoparticle Spectroscopy (AC-SINS) < 10 shift, size-exclusion chromatography (SEC or aSEC) > 85% monomer, a poly-specificity reagent binding via dissociation-enhanced lanthanide fluorescence immunoassay (PSR-DELFIA or PSR) < 10 fold-change, hydrophobic interaction chromatography (HIC or aHIC) < 10 minutes retention time) and similar binding kinetics relative to the Reference Antibody.Affinity Maturation Campaign
[0432] A set of 164 variants was screened of which 16 were further selected for functional screening. No variants exhibited improved functionality.Example 2. Binding AssaysSurface Plasmon Resonance (SPR)
[0433] Surface plasmon resonance (SPR) was employed to determine the kinetics and affinities of binding of a panel of interleukin 4 receptor subunit alpha (IL-4Ra) antibodies to human IL-4Ra. The Carterra LSA and Cytiva Biacore 8K+ instruments are label-free platforms that use SPR to measure binding interactions in real-time. Kinetic and affinity parameters were extracted from experimental data by an iterative process that found the best fit for a set of equations describing the interaction. The association rate constant ka (M^s'1) describes the rate at which a complex was formed. The dissociation rate constant kd (s'1) describes the rate at which a complex dissociated. The equilibrium dissociation constant KD (M) describes the strength of the interaction.Carterra LSA Non-Regenerative Capture Kinetics
[0434] To evaluate the affinities of binding of a panel of anti-IL-4Ra antibodies to human IL-4Ra at 25 °C, a non-regenerative capture kinetics approach was performed using a Carterra LSA instrument (Carterra, Salt Lake City, UT). A goat anti-human polyclonal antibody lawnwas prepared via amine-coupling onto a poly carboxylate hydrogel (HC30M) sensor chip using a single flow cell (SFC) to attain approximately 5,000 response units (RU). Each antibody was prepared at 8 pg / mL and captured onto regions of interest (ROI) for 15 min using four serial dockings of a 96-channel printhead (96PH) to create a 384-antibody array. Human IL-4Ra was prepared in HBSTE + BSA (10 mM HEPES pH 7.4, 150 mM NaCl, 3 mM EDTA, 0.01% Tween 20, 0.5 mg / mL BSA) running buffer and injected over the captured antibody array surface at nine concentrations in a 3 -fold serial dilution series from 1000 nM to 0.2 nM. Each analyte concentration was injected sequentially from low to high concentration in a single cycle using the SFC with a 5-min association phase and a 10-min dissociation phase. The surface was regenerated by injecting two pulses of 0.85% phosphoric acid for 15 seconds between each cycle. The assay was performed at 25°C with technical replicates. Kinetic parameters for the concentration series were obtained by double referencing and globally fitting the data to a 1 : 1 binding model with the 5% kd option selected using the Kinetics analysis software (Carterra). The affinities of human IL-4Ra binding to a panel of IL-4Ra antibodies were reported, and the results were expressed as the average ± standard deviation of one independent experiment with technical replicates (Table 7).Table 7, Carterra LSA Non-regenerative Capture Kinetics.Biacore 8K+ Multi-Cycle Capture Kinetics
[0435] To evaluate the kinetics of bindings of select anti-IL-4Ra antibodies to human IL- 4Ra at 25 °C, a multi-cycle capture kinetics approach was implemented using a Biacore 8K± instrument (Cytiva, Marlborough, MA). A goat anti-human polyclonal antibody surface was prepared via amine-coupling onto a carboxymethylated dextran (CM4) sensor chip to attainapproximately 5,000 response units (RU). Each antibody was prepared at 2-9 pg / mL and captured for 30 s at a flow rate of 10 pL min1to achieve a capture level of approximately 150 RU. Human IL-4Ra was prepared in HBS-EP+ (10 mM HEPES pH 7.4, 150 mM NaCl, 3 mM EDTA, and 0.05% v / v surfactant P20) running buffer and injected over the captured antibody surface at six concentrations in a 3-fold serial dilution series from 30 nM to 0.1 nM. Each analyte concentration was injected in a separate cycle for 180 seconds at a flow rate of 30 pL min and the complex was allowed to dissociate for 3,600 seconds. The surface was regenerated by injecting two pulses of 0.85% phosphoric acid for 20 seconds at a flow rate of 30 pL min1in between each cycle. The assay was performed at 25 °C with technical replicates. Kinetic parameters for the concentration series were obtained by double referencing and globally fitting the data to a 1 : 1 binding model using the Biacore Insight Evaluation software (Cytiva). The kinetics and affinities of human IL-4Ra binding to select IL-4Ra antibodies were reported, and results were expressed from a global fit of replicate data of one independent experiment (Table 8).Table 8, Multi-Cycle Kinetics with Sample as Ligand (Biacore 8K+),LS = IgG4 LS variantYTE = IgG4 YTE variantExample 3. Functional AssaysHuman IL-4Ra Binding Assay (Indirect ELISA)
[0436] Binding affinity of antibodies to human IL-4Ra was assessed using an indirect enzyme-linked immunosorbent assay (ELISA). A 96-well half-area plate was coated with 2 pg / mL of recombinant human IL-4Ra (BioLegend, San Diego, CA) overnight. The next day, the plate was washed three times with ELISA Wash Buffer (phosphate-buffered saline (PBS)- Tween 0.5%), blocked with lx ELISA diluent (BioLegend) for one hour. The plates were then washed three times with ELISA Wash Buffer, followed by addition of the anti-IL-4Ra antibodies (1 :5 serial dilution 8-point curve starting at 5pg / mL antibody) and incubated at 37°C for one hour. The plate was washed three times with ELISA Wash Buffer. Horseradishperoxidase (HRP)-conjugated anti-human immunoglobulin G fragment crystallizable region (IgG Fc) secondary antibody (Promega Corporation, Madison, WI) at 1 :2000 dilution in lx ELISA diluent was added to detect binding of the primary antibody to the antigen. The plate was incubated for 30 minutes at 37°C with the secondary detection antibody, then the plate was washed and developed with 3,3',5,5'-tetramethylbenzidine (TMB) substrate solution (Thermo Fisher Scientific, Waltham, MA). The HRP enzymatic reaction was stopped after about 1 minute with acidic stop solution (Thermo Fisher Scientific), and the absorbance at 450 nm (A450) was determined using a standard plate reader (FIGs. 4A-4C).HEK-Blue Blocking Assay
[0437] The ability of an antibody to block binding of IL-4 / 13 to IL-4Ra was assessed using the HEK (human embryonic kidney)-Blue colorimetric assay. HEK-Blue cells are an engineered cell line developed by InvivoGen (San Diego, CA); these modified HEK cells have the gene for secreted alkaline phosphatase (SEAP) inserted within the locus activated by Signal Transducer and Activator of Transcription 6 (STAT6) downstream of IL-4 / IL-4Ra binding. When SEAP interacts with InvivoGen’ s QUANTLBlue solution, a reaction turns the liquid from pink to blue.
[0438] For this assay, HEK-Blue cells were grown to confluency in a media comprising DMEM + GLUTAMAX® (Gibco, Waltham, MA), 10% fetal bovine serum (FBS), 1% Penicillin-Streptomycin (Gibco), and 100 pg / mL Normocin (InvivoGen). Cells were removed from their flasks using 0.25% trypsin-EDTA (Gibco), washed in media, and replated in a 96- well flat-bottom plate at 1 million cells per milliliter, and 100 pl per well. The cells were then blocked with the anti-IL-4Ra antibody at a concentration curve for thirty minutes at 37°C. Afterwards, they were incubated overnight with lOOpl of 5 ng / mL human IL-4 / 13 cytokine (ACROBiosystems, Newark, DE).
[0439] The next day, 20 pl of cell supernatant was extracted from each well and mixed with 180 pl of QUANTLBlue solution (InvivoGen). This mixture was then allowed to develop in the dark for thirty minutes at room temperature. After developing, the absorbance was measured on a plate reader at 635 nm, indicating the amount of SEAP produced and thus the level of IL-4 / IL-4Ra binding in the cells despite antibody blocking (FIGs. 5A-5C).IL-4Ra Human Primary B Cell-based Assay (CD23 Inhibition)
[0440] Frozen peripheral blood mononuclear cells (PBMCs) from Donors were thawed, and B cells were isolated from frozen cell samples using the B cell isolation kit from STEMCELL Technologies (Vancouver, Canada; Cat. No. 17954) following the manufacturer’s instructions. A sample from each donor was taken and stained using the B cell flow panel listed in the table below to check purity of the B cell population.* Becton, Dickinson and Company (BD), Franklin Lakes, NJ
[0441] After isolation, B cells were plated at 3 x io5cells in 100 pL CIO media in a 96 well U-bottom plate and rested overnight at 37°C. The following day, anti-IL-4Ra antibody was added in 50 pL (3-fold 10-point curve starting at 150 pg / mL antibody) and incubated for 30 minutes at 37°C. IL-4 cytokine (BioLegend Cat. No. 574006) was added in 50 pL of media for controls to a final concentration of cytokine of 10 ng / mL in the assay. Total assay volume was 200 pL and was incubated for 48 hours. After 48 hours, the cells were stained according to the staining protocol in the table below to identify CD23 inhibition by anti-IL- 4Ra antibodies.- I l l -
[0442] Inhibition of CD23 expression was reported from 4 donors as IC50 (Table 9) and percent inhibition (FIGs. 6A-6D).Table 9. Inhibition of CD23 Expression by Primary B cells (IC50)LS = IgG4 LS variantYTE = IgG4 YTE variantRamos CD23 Inhibition Assay
[0443] Ramos (RAI) cells (ATCC, Manassas, VA; Cat. No. CRL-1596) were harvested when the cell density was greater than 3 * 106cells / mL. Ramos cells were plated at 3 * 105cells in 100 pL RPMI 1640 with 10% FBS and 1% Pen Strep media in a 96 well U-bottom plate. Anti-IL-4Ra antibody was added in 50 pL (3-fold 8-point curve starting at 30 pg / mL antibody) and was incubated for 30 minutes at 37°C. 50 pL IL-4 cytokine (BioLegend Cat. No. 574006) was added for a final concentration of 10 ng / mL of cytokine in a total assay volume of 200 pL. In control experiments, 50 pL media was added. The assay was incubated for 24 hours. After 24 hours, the cells were stained according to the protocol set forth in the tables below to identify CD23 inhibition by anti-IL-4Ra antibodies.
[0444] Results were reported as percent inhibition (FIG. 7).Example 4. Translational Assays pSTAT6 Whole Blood Assay
[0445] The objective was to evaluate IL-4Ra target engagement in primary cells via functional inhibition of relevant atopic dermatitis (AD) biomarkers, such as phosphorylated Signal Transducer and Activator of Transcription 6 (pSTAT6), and Thymus- and Activation- Regulated Chemokine (TARC or CCL17). Assay development, optimization, and proof-of- concept were done using the Reference (anti-IL-4Ra mAb) in peripheral blood mononuclear cells (PBMCs) and ultimately transferred into whole blood across three distinct donors.
[0446] See tables below for a list of materials used in this assay.*R&D Systems, Minneapolis, MN**eBioscience, Waltham, MA***BD Biosciences, Franklin Lakes, NJ
[0447] A volume of 180 pL / well of whole blood was plated in RPMI-1% FBS, in a 96 well flat bottom plate. Appropriate concentration of mAb was added at 20x (in a volume of 10 pL). The plate was incubated at 37°C for 20 minutes. Either 10 ng / mL or 1 ng / mL of rh- IL-4 was then added in 20x (volume of lOpL). The plate was incubated at 10 minutes at 37°C. The plate was centrifuged, and the supernatant was aspirated to leave a volume of about 100 pL.
[0448] Stimulation was then stopped by addition of Lyse / Fix buffer (BD) at a volume of 20 times the remaining volume of the blood. The samples were vigorously mixed via pipetting and then incubated at 37°C for 10-15 minutes during lysing of red blood cells (RBCs) and fixation. The cells were then washed twice in flow cytometry staining buffer and stained with fixable viability dye and FC block for 15 minutes at 4°C. Extracellular markers were added according to the concentrations suggested by manufacturer’s instructions. The cells were then washed 2x with flow cytometry staining buffer before being resuspended in BD Phosflow Perm II buffer for 30 minutes. The cells were once again washed as describedpreviously and resuspended in intracellular staining markers (pSTAT6) according to manufacturer’s instructions for 30 minutes at room temperature. After final 2 washes, the cells were resuspended in flow cytometry staining buffer, run on Attune CytPix flow cytometer (Invitrogen), and analyzed using FlowJo software (FlowJo, Ashland, OR). The graphs of data exported from FlowJo were visualized and statistically analyzed using GraphPad Prism (GraphPad Software, Boston, MA).
[0449] In the presence of IL-4, there was a dose-dependent decrease in pSTAT6 expression with both the Reference (hIgG4) and AB-13c (hIgG4) in both B cells (CD19+) and T cells (CD4+) (FIGs. 8 A, 8B). These results were consistent with the data obtained from two additional whole blood donors (FIGs. 8C, 8D). The dose-dependent decreases in pSTAT6 were comparable between the Reference and AB-13c in whole blood. Minimal impact from the biological matrix of whole blood (matrix effect) was observed as evidenced by the ability of the respective antibodies to retain pSTAT6 modulation, indicative of functional inhibition of IL-4Ra.TARC release (from PBMCs) assay
[0450] The objective was to evaluate IL-4Ra target engagement in primary cells via functional inhibition of relevant atopic dermatitis (AD) biomarkers, such as phosphorylated Signal Transducer and Activator of Transcription 6 (pSTAT6) and Thymus- and Activation- Regulated Chemokine (TARC or CCL17). TARC release can be used as a functional readout of anti-IL-4Ra activity via ELISA readout. Assay development, optimization and proof-of- concept experiments were done using the Reference (hIgG4 IL-4Ra mAb) in PBMCs. AB- 13c (hIgG4) was tested in comparison to the Reference in one donor. The assay was optimized to be used in further potential uses of AB- 13 c.
[0451] See table below for a list of materials used in this assay.
[0452] PBMCs were plated in a 96 well flat bottom plate at about 5* 104to about 1 * 105cells per well in a volume of 50 pL of RPMI-10% FBS. An appropriate concentration of mAb was added at 2x (in a volume of 50pL). The plate was incubated at 37°C for 20 minutes.Zero, 1, or 10 ng / mL of rh-IL-4 was then added in 3x (volume of 50 pL). The plate was then incubated at 37°C for 48-72 hours and then centrifuged. The supernatants were collected and frozen at -80°C until use. Undiluted samples were run in accordance with manufacturer’s instructions for the Human CCL17 / TARC QUANTIKINE® ELISA kit (R&D Systems). Optical density (OD) of the samples were read at 450 nM on a spectrophotometer. The data was analyzed using a nonlinear regression curve and graphed using GraphPad Prism software.
[0453] A dose-dependent induction of TARC release in response to rh-IL-4 stimulation was observed (FIG. 9A). An ideal range for IL-4 stimulation was from 0.1 to 100 ng / mL. At different levels of IL-4 stimulation (1, 10, and 100 ng / mL IL-4), AB-13c showed a degree of TARC suppression comparable to the Reference (FIGs. 9B-9D).
