Description

[0001] This application is a divisional application of the patent application with the application date of November 19, 2020, the Chinese patent application number of 202080080856.8, and the invention title of "antibody-containing preparation". Technical Field

[0002] The present invention relates to a stable preparation comprising an interleukin-31 (IL-31) antagonist (e.g., a monoclonal antibody having the function of binding to IL-31 receptor A (IL-31RA) and inhibiting the binding of IL-31 to IL-31RA). Background Art

[0003] Monoclonal antibodies (PTL1-3) having the function of binding to interleukin 31 (IL-31) receptor A (IL-31RA) and inhibiting the binding of IL-31 to IL-31RA have been identified. The anti-IL-31RA antibody Nemolizumab (CIM331), a humanized IgG2 antibody, is used as an IL-31 antagonist to inhibit the function of IL-31, a so-called pruritogenic cytokine; thus, clinical trials for patients with atopic dermatitis are currently underway.

[0004] To improve stability, many lyophilized preparations (NPL 1) for therapeutic proteins (such as antibodies) have been developed to date. As additives for lyophilized preparations of non-antibody therapeutic proteins, saccharides such as sucrose and trehalose (NPL 2) are usually used, and there are also reports of using arginine as a stabilizer (PTL4 and 5).

[0005] However, there is no report on a stable preparation that inhibits the formation of aggregates and / or components having charge heterogeneity, which have a great influence on antibody stability, for a preparation comprising an anti-IL31RA antibody (CIM331) as an IL-31 antagonist.

[0538] IL-31 (Interleukin-31) is a T cell cytokine. It is known that IL-31 is associated with itching. In transgenic mice overexpressing IL-31, dermatitis-like symptoms similar to atopic dermatitis appear, and continuous scratching behavior is observed.

[0539] The nucleic acid sequence and amino acid sequence of human IL-31 are also referred to as RefSeq accession numbers NM_001014336 and NP_001014358, respectively.

[0540] The IL-31 receptor is formed by a heterodimer of IL-31 receptor A (IL-31RA) and oncostatin M receptor (OSMR) (Nat Immunol (2004) 5, 752-60). IL-31RA, also known as NR10, is known to have multiple splice variants (WO00 / 075314). The known splice variants are NR10.1 (652 amino acids), NR10.2 (252 amino acids), NR10.3 (662 amino acids, also known as IL-31RAv4), IL31RAv3 (764 amino acids), etc. Preferred examples of IL-31RA include NR10.3 (IL-31RAv4) and IL-31RAv3. The nucleic acid sequence and amino acid sequence of human IL-31RA (IL-31RAv4) are also known as RefSeq accession number NM_001242638 and RefSeq accession number NP_001229567, respectively. The nucleic acid sequence and amino acid sequence of human IL-31RA (IL-31RAv3) are also known as RefSeq accession number NM_139017 and RefSeq accession number NP_620586, respectively. The nucleic acid sequence and amino acid sequence of human OSMR are also known as RefSeq accession number NM_003999 and RefSeq accession number NP_003990, respectively.

[0541] In one embodiment, the IL-31 antagonist of the present disclosure refers to a compound that inhibits or blocks IL-31-induced intracellular signal transduction. Such a compound can also be expressed as a compound that inhibits IL-31 signaling. Such a compound can be a naturally occurring compound or a synthetic compound. In addition, such a compound can be a low molecular weight compound or a high molecular weight compound such as a protein.

[0542] IL-31, which is known to exist extracellularly, triggers intracellular signal transduction through the IL-31 receptor (a heterodimer of IL-31RA and OSMR) present on the cell surface (Nat Immunol (2004) 5, 752-760). The extracellular domain of the IL-31 receptor includes an IL-31 binding domain, and the binding of IL-31 thereto causes a conformational change in the IL-31 receptor. Thus, intracellular signal transduction starts from the intracellular domain of the IL-31 receptor.

[0543] In one method, it can be verified whether a compound inhibits IL-31 signaling by checking whether the compound inhibits the binding of IL-31 to the IL-31 receptor. Examples of methods for making such a determination include assays using ELISA or flow cytometry and assays using surface plasmon resonance. Taking ELISA as an example, it can be evaluated whether a compound inhibits the binding of IL-31 to the IL-31 receptor by immobilizing the IL-31 receptor (or IL-31RA) protein on a plate, preparing a system for detecting the amount of IL-31 protein bound thereto by using a secondary antibody such as an enzyme-labeled anti-IL-31 antibody, and determining whether the addition of the compound reduces the amount of detected IL-31 protein.

[0544] In an alternative method, it can be verified whether a compound inhibits IL-31 signaling by checking whether a biological activity induced by the action of IL-31 on cells is inhibited by the compound. The biological activity is not particularly limited as long as it can be quantitatively or qualitatively determined by any method, and examples of such biological activities include cell proliferation activity, protein phosphorylation activity, and gene / protein expression induction activity. For example, whether the compound inhibits IL-31 signaling can be evaluated by: preparing cells that express the IL-31 receptor on the surface and whose proliferation activity is induced in response to external IL-31 stimulation, and determining whether the addition of the compound reduces the IL-31-induced cell proliferation activity. As such cells, naturally occurring cells that inherently express the IL-31 receptor can be used, or recombinant cells that are artificially synthesized to express the IL-31 receptor can be used. Suitable examples of recombinant cells include Ba / F3 cells that express the IL-31 receptor. As a further alternative, the method described in the document by Dillon et al. (Nat Immunol (2004) 5, 752-760) can be used.

[0545] In the present invention, the degree of inhibition of IL-31 signaling by the IL-31 antagonist can be, but is not limited to, at least 10% or more, preferably 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, particularly preferably 90% or more, 95% or more, and 98% or more.

[0546] In the present disclosure, preferred embodiments of compounds that inhibit IL-31 signaling include proteins that inhibit IL-31 signaling. The proteins used herein are not particularly limited as long as they have the property of specifically binding to IL-31 or an IL-31 receptor. Examples of preferred proteins include antibodies and antibody-like molecules (Curr Opin Biotechnol (2006) 17, 653-658; Curr Opin Struct Biol (1997) 7, 463-469; and Protein Sci (2006) 15, 14-27). Antibodies include any antibody, such as monoclonal antibodies (e.g., IgG, IgM, IgE, IgA, and IgD), polyclonal antibodies, engineered antibodies (e.g., chimeric antibodies, humanized antibodies, and glycoengineered antibodies (WO 99 / 54342 and WO00 / 61739)), antibody fragments (e.g., Fab, F(ab')2, Fv, and CDR), multispecific antibodies (e.g., bispecific antibodies), and conjugated antibodies (e.g., antibodies conjugated with polyethylene glycol (PEG), radioisotopes, or drugs). On the other hand, examples of antibody-like molecules include DARPin (WO 2002 / 020565), Affibody (WO 1995 / 001937), Avimer (WO 2004 / 044011), and Adnectin (WO 2002 / 032925). More preferred are antibodies that inhibit IL-31 signaling. Examples of other preferred proteins that inhibit IL-31 signaling include proteins containing the extracellular domain of IL-31RA and proteins containing each extracellular domain of the IL-31 receptor (heterodimer of IL-31RA and OSMR).

[0547] In the present disclosure, preferred embodiments of antibodies that inhibit IL-31 signaling include antibodies that inhibit IL-31 signaling by binding to IL-31 (anti-IL-31 neutralizing antibodies) and antibodies that inhibit IL-31 signaling by binding to the IL-31 receptor (anti-IL-31 receptor neutralizing antibodies). Anti-IL-31 receptor neutralizing antibodies include antibodies that inhibit IL-31 signaling by binding to IL-31RA (anti-IL-31RA neutralizing antibodies), antibodies that inhibit IL-31 signaling by binding to OSMR (anti-OSMR neutralizing antibodies), and antibodies that inhibit IL-31 signaling by binding to the heterodimer of IL-31RA and OSMR (anti-IL-31RA / OSMR heterodimer neutralizing antibodies). Among these anti-IL-31 receptor neutralizing antibodies, anti-IL-31RA neutralizing antibodies or anti-IL-31RA / OSMR heterodimer neutralizing antibodies are preferred, and anti-IL-31RA neutralizing antibodies are more preferred.

[0548] The antibodies used in the present invention are not particularly limited as long as they bind to the desired antigen to inhibit IL-31 signaling, and they can be polyclonal antibodies or monoclonal antibodies. Monoclonal antibodies are preferred because homogeneous antibodies can be produced stably.

[0549] The amino acids contained in the amino acid sequence of the present invention can be post-translationally modified (for example, modification of the N-terminal glutamine to pyroglutamic acid by pyroglutamylation is well known to those skilled in the art). Naturally, such post-translationally modified amino acids are included in the antibodies used in the present invention.

[0550] In a further embodiment or another embodiment, the antibodies that inhibit IL-31 signaling of the present disclosure preferably comprise an amino acid variant of the H-chain constant region sequence of IgG2, wherein the amino acid variant comprises glutamic acid at position 419 (EU numbering) in the H-chain constant region sequence of wild-type IgG2 (SEQ ID NO: 12). Compared with a reference antibody comprising the H-chain constant region sequence of wild-type IgG2 having the same amino acid sequence except for the amino acid change at position 419, the engineered antibody has the advantage that it exhibits an increased plasma half-life. It is believed that this increased plasma half-life is caused by a decrease in the isoelectric point (pI) induced by replacing the amino acid with glutamic acid at position 419 (Example 2 of WO 2016 / 167263).

[0551] Thus, in one embodiment, the lyophilized and solution formulations of the present disclosure are advantageous as they relate to lyophilized and solution formulations for providing an increased plasma half-life relative to (reference) lyophilized and solution formulations comprising a reference antibody, wherein the reference antibody comprises the H-chain constant region sequence of wild-type IgG2 having the same amino acid sequence except for an amino acid change at position 419.

[0552] In this case, in a preferred embodiment, the antibody that inhibits IL-31 signaling of the present disclosure is any one of the following anti-IL-31RA neutralizing antibodies:

[0553] (1) An anti-IL-31RA antibody comprising an H-chain variable region and an L-chain variable region, wherein the H-chain variable region comprises CDR1 shown in SEQ ID NO: 1, CDR2 shown in SEQ ID NO: 2, and CDR3 shown in SEQ ID NO: 3, and the L-chain variable region comprises CDR1 shown in SEQ ID NO: 4, CDR2 shown in SEQ ID NO: 5, and CDR3 shown in SEQ ID NO: 6;

[0554] (2) An anti-IL-31RA antibody comprising the H-chain variable region shown in SEQ ID NO: 7 and the L-chain variable region shown in SEQ ID NO: 8; and

[0555] (3) An anti-IL-31RA antibody comprising the H-chain shown in SEQ ID NO: 9 and the L-chain shown in SEQ ID NO: 10.

[0556] It should be understood that the isoelectric point (pI), also simply referred to as "pI", can be the theoretical isoelectric point or the experimentally measured isoelectric point, which is not explicitly described in this specification unless there is a contradiction in the context.

[0557] For example, the value of the isoelectric point can be measured by isoelectric focusing known to those skilled in the art. The value of the theoretical isoelectric point can be calculated using gene and amino acid sequence analysis software (e.g., Genetyx). Alternatively, the value of the theoretical isoelectric point can be measured by conducting pharmacokinetic studies of the antibody using, for example, plasma from mice, rats, rabbits, dogs, monkeys, humans, etc. in combination with methods known to those skilled in the art such as BIACORE, cell proliferation assays, ELISA, EIA (enzyme immunoassay), RIA (radioimmunoassay), or immunofluorescence.

[0558] Whether the plasma half-life of the antibody changes before and after amino acid variation (modification) can be verified by conducting pharmacokinetic studies of the antibody using, for example, plasma from mice, rats, rabbits, dogs, monkeys, humans, etc., which are known to those skilled in the art.

[0559] The antibody that inhibits IL-31 signaling according to the present disclosure, in yet another or another embodiment, preferably does not (substantially) exhibit cross-reactivity with IL-31RA from any one of mouse, rat, and rabbit, although it has cross-reactivity with IL-31RA from human and cynomolgus monkey.

[0560] Methods for preparing antibodies are well known to those skilled in the art. For example, antibodies can be prepared using the hybridoma method (Nature (1975) 256, 495) or the phage antibody library method (Nature (1991) 352, 624-628; J Mol Biol (1991) 222, 581-597). Using IL-31 protein or IL-31 receptor protein as an immunogen, a large number of anti-IL-31 antibodies or anti-IL-31 receptor antibodies can be obtained by these methods. In addition, screening these antibodies using any of the methods for detecting compounds that inhibit IL-31 signaling allows for the obtaining of anti-IL-31 neutralizing antibodies or anti-IL-31 receptor neutralizing antibodies. Genetic engineering techniques known to those skilled in the art can also be used to prepare proteins such as IL-31 or IL-31 receptor. Specifically, such proteins can be prepared by inserting a gene encoding the target protein into an expression vector, introducing the vector into an appropriate host cell, and then purifying the target protein expressed in the host cell or the culture supernatant of the host cell.

[0561] Examples of preferred anti-IL-31 neutralizing antibodies include the anti-IL-31 antibodies described in WO 2006 / 122079, WO 2008 / 028192, and WO2009 / 071696.

[0562] Examples of preferred anti-IL-31RA neutralizing antibodies include, but are not limited to, the anti-IL-31RA (NR10) antibody described in WO 2007 / 142325, the anti-IL-31RA (NR10) antibody described in WO 2009 / 072604, and the anti-IL-31RA (NR10) antibody described in WO 2010 / 064697.

[0563] In addition, other examples of preferred anti-IL-31RA neutralizing antibodies include anti-human IL-31RA (neutralizing) antibodies, specifically including anti-IL-31RA (neutralizing) antibodies that recognize domain 1 and / or domain 2 of human IL-31RA. As used herein, domain 1 of human IL-31RA refers to the region from amino acid position 53 to amino acid position 152 (LPAKP to LENIA) in the amino acid sequence shown in SEQ ID NO: 11. Domain 2 refers to the region from amino acid position 153 to amino acid position 259 (KTEPP to EEEAP) in the amino acid sequence shown in SEQ ID NO: 11.

[0564] Without any limitation, among anti-IL-31RA neutralizing antibodies, more preferred is the anti-IL-31RA antibody described in WO 2010 / 064697, which comprises an H-chain (heavy chain) variable region and an L-chain variable region, wherein the H-chain (heavy chain) variable region comprises CDR1 shown in SEQ ID NO: 1, CDR2 shown in SEQ ID NO: 2, and CDR3 shown in SEQ ID NO: 3, and the L-chain variable region comprises CDR1 shown in SEQ ID NO: 4, CDR2 shown in SEQ ID NO: 5, and CDR3 shown in SEQ ID NO: 6. Even more preferred is the anti-IL-31RA antibody that comprises the H-chain variable region shown in SEQ ID NO: 7 and the L-chain (light chain) variable region shown in SEQ ID NO: 8. Particularly preferred is Nemolizumab (CIM331), which is an anti-IL-31RA antibody comprising the H-chain shown in SEQ ID NO: 9 and the L-chain shown in SEQ ID NO: 10.

[0565] Known methods for defining CDRs include the method according to Kabat et al. (Sequences of Proteins of Immunological Interest, 5th Edition (1991), Bethesda, MD), the method according to Chothia et al. (Science (1986) 233, 755-758), and the method based on the antigen-antibody contact region (J Mol Biol (1996) 262, 732-745). Specifically, each method defines CDRs as follows:

[0566]

[0567] Examples of preferred anti-IL-31RA neutralizing antibodies of the present disclosure include anti-IL-31RA antibodies that comprise CDR1, CDR2, and CDR3 contained in the heavy chain variable region shown in SEQ ID NO: 7, and CDR1, CDR2, and CDR3 contained in the light chain variable region shown in SEQ ID NO: 8, as heavy chain CDR1, CDR2, and CDR3 and light chain CDR1, CDR2, and CDR3, respectively. The CDRs in such antibodies can be defined according to any one of the methods of Kabat et al., Chothia et al., and the method based on the antigen-antibody contact region, or according to a combination of these methods.

[0568] Similarly, as an anti-IL-31RA neutralizing antibody, an anti-IL-31RA antibody that preferably binds to the same epitope as the anti-IL-31RA antibody defined by the CDR sequences of the heavy and light chains, the heavy and light chain variable region sequences, and the full-length heavy and light chain sequences described above is preferred. An epitope refers to a specific structural unit of an antigen that an antibody recognizes and binds to. When the antigen is a polypeptide, an epitope usually consists of about 6 to 10 amino acids. Epitope identification can be carried out using methods known to those skilled in the art, such as the method of fragmenting the antigen to synthesize peptides, the method of introducing site-directed mutagenesis into the antigen (e.g., arginine / glutamic acid scanning, J Biol Chem (1995) 270, 21619-21625; J Biol Chem (2006) 281, 20464-20473), and the method of crystallizing the antigen-antibody complex (Using Antibodies: A Laboratory Manual (1999), Cold Spring Harbor Laboratory Press, New York). In the present disclosure, the statement "binds to the same epitope" means that the epitopes bound by the two antibodies at least partially overlap with each other. The degree of overlap is but not limited to at least 10% or more, preferably 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, particularly preferably 90% or more, and most preferably 100%.

[0569] Similarly, preferred as the anti-IL-31RA neutralizing antibody is an anti-IL-31RA antibody that competes with the anti-IL-31RA antibody defined by the CDR sequences of the above-mentioned heavy and light chains, the variable region sequences of the heavy and light chains, and the full-length heavy and light chain sequences for binding to IL-31RA. For example, whether two antibodies compete with each other can be evaluated by a competitive binding assay using ELISA. The specific method is as follows: One of the two antibodies is pre-labeled with, for example, fluorescence. A system for detecting the binding of the antibody (labeled antibody) to the antigen is prepared. The case where the other unlabeled antibody (test antibody) coexists is compared with the case where the test antibody does not coexist in the system. If the binding level of the labeled antibody to the antigen decreases in the presence of the test antibody, it can be determined that the test antibody and the labeled antibody compete with each other. In the present disclosure, the degree of competition is, but not particularly limited to, at least 10% or more, preferably 20% or more, 30% or more, 40% or more, 50% or more, 60% or more, 70% or more, 80% or more, particularly preferably 90% or more, 95% or more, 98% or more (i.e., the binding level of the other antibody decreases).

[0570] Atopic dermatitis in the present disclosure may preferably be atopic dermatitis caused by or induced by IL-31 signaling, or atopic dermatitis that exhibits responsiveness to the prevention and / or treatment with an IL-31 antagonist, but is not limited thereto.

[0571] The pruritus in the present disclosure may be pruritus caused by atopic dermatitis, preferably pruritus caused by atopic dermatitis caused by or induced by IL-31 signaling, but is not limited thereto. In addition, the pruritus may be pruritus caused by atopic dermatitis that exhibits responsiveness to the prevention and / or treatment with an IL-31 antagonist.

[0572] For example, atopic dermatitis may be moderate to severe atopic dermatitis, and may preferably be moderate or severe atopic dermatitis in which topical treatment is not sufficiently effective or not tolerated, or standard topical treatment is not sufficiently effective or not tolerated, or standard topical treatment is prohibited (due to contraindications, etc.). More preferably, atopic dermatitis may be moderate or severe atopic dermatitis in which topical treatment is not sufficiently effective or not tolerated.

[0573] For topical treatment, for example, topical steroids (e.g., glucocorticoids or their derivatives, such as prednisolone and hydrocortisone) and topical calcineurin inhibitors known as immunosuppressants (e.g., tacrolimus and pimecrolimus) are known.

[0574] In addition to topical steroids and topical calcineurin inhibitors, agents such as cyclosporine, methotrexate (MTX), or azathioprine (AZA), or antihistamines (various drugs are called antihistamines and are roughly classified into first-generation antihistamines and second-generation antihistamines) are known as therapeutic agents for atopic dermatitis.

[0575] More specifically, without any limitation, the following treatment methods are known for the treatment of atopic dermatitis ("Therapeutic Guidelines for Atopic Dermatitis", Furue et al., the Japanese journal of dermatology: 119 (8), pp. 1515-1534, 2009; "Guidelines of care for the management of atopic dermatitis: section 3. Management and treatment with phototherapy and systemic agents.", Sidbury R et al., J Am Acad Dermatol. (2014), pp. 327-337); and Saeki H et al., J Dermatol 2009, 36, pp. 563-77).

[0576] (1) Cyclosporine preparation (trade name: Neoral)

[0577] Usually, the cyclosporine preparation is orally administered to adults at a dose of 3 mg / kg per day, taken twice a day in terms of cyclosporine. The dose should not exceed 5 mg / kg per day, but may vary as appropriate according to symptoms.

[0578] (2) Oral administration of steroid preparation (trade name: Prednisolone tablets)

[0579] Usually, the steroid preparation is orally administered to adults at a dose of 5 to 60 mg per day, calculated as prednisolone (in the case of tablets, 1 to 12 tablets; in the case of powder, 0.5 grams to 6 grams), taken one to four times. The dose will vary as appropriate according to age or symptoms.

[0580] (3) Ultraviolet therapy

[0581] Although there is no established manual or guideline, it is generally said that patients need to go to the hospital once or twice a week.

[0582] (4) Antihistamine preparation (trade name: Allegra)

[0583] Typically, the antihistamine preparation is orally administered to adults at a single dose of 60 mg (calculated as fexofenadine hydrochloride) twice a day. Typically, the antihistamine preparation is orally administered to children aged 7 years or older and less than 12 years at a single dose of 30 mg (calculated as fexofenadine hydrochloride) twice a day, and to children 12 years or older at a single dose of 60 mg, calculated as fexofenadine hydrochloride, twice a day. The dose will vary as appropriate according to the symptoms.

[0584] (5) Topical steroid preparation (trade name: Fulmeta)

[0585] Typically, an appropriate amount of the topical steroid preparation is applied to the affected area once to several times a day. The dosage will vary as appropriate according to the symptoms.

[0586] (6) Topical steroid preparation (trade name: Locoid)

[0587] Typically, an appropriate amount of the topical steroid preparation is applied once to several times a day. The dosage will vary as appropriate according to the symptoms.

[0588] (7) Tacrolimus preparation (trade name: Protopic)

[0589] Typically, for adults, an appropriate amount of the tacrolimus preparation is applied to the affected area once or twice a day. The dosage for each application should be up to 5 grams.

[0590] (8) Pimecrolimus preparation (trade name: Elidel)

[0591] Typically, an appropriate amount of the pimecrolimus preparation is applied twice a day. The dosage will vary as appropriate according to the symptoms.

[0592] The severity of atopic dermatitis (e.g., mild, moderate, or severe) can be classified based on classification methods known to those skilled in the art for scoring the degree of rash or itching felt by a subject, such as Shiratori's severity criteria, the Visual Analogue Scale (VAS) described below, the Verbal Rating Scale for Itching (VRS), the Atopic Dermatitis Score (SCORAD) established by the European Task Force on Atopic Dermatitis, the Eczema Area and Severity Index (EASI) established in the United States, or, for example, the static Investigator's Global Assessment (sIGA).

[0593] For example, the VAS consists of a 100 mm straight line, and the subject (patient) indicates the intensity of itching during measurement by drawing a line between 0 and 100 mm on this straight line, where 0 mm indicates no itching and 100 mm represents the most severe itching imaginable. For example, a subject determined to have a VAS score of 40 mm or higher can be identified as having moderate to severe atopic dermatitis, and in one embodiment, the VAS score can be 45 mm or higher, or 50 mm or higher. Similarly, in the case of the VRS, for example, a subject classified at the "moderate itching" level or higher may be considered to have moderate to severe atopic dermatitis (Reich et al., 2012). Or, for example, in the evaluation of the degree of itching during the day or night based on Shirator's severity criteria, a subject determined to have an EASI score of 10 or more, an sIGA score of 3 or more, or an overall score of 4 or more can be considered to have moderate to severe atopic dermatitis. Or, a subject in whom a rash with severe inflammation affects, for example, 5% or more of the body surface area can be identified as having moderate to severe atopic dermatitis. Or, if appropriate, a subject who meets a combination of one or more of the indicators mentioned herein can be considered to have moderate to severe atopic dermatitis.

[0594] As used herein, a "subject" can preferably be an animal, more preferably a mammal (such as a mouse, rat, rabbit, dog, monkey (such as a cynomolgus monkey), etc.), and particularly preferably a human, but is not limited thereto. A human can be an adult (18 years old or older) or a child (0 to less than 18 years old, for example, 6 months to less than 18 years old).

[0595] In one embodiment, the present disclosure relates to a lyophilized preparation and a solution preparation for preventing and / or treating atopic dermatitis, which contain an IL-31 antagonist as an active ingredient.

[0596] In this case, using a predetermined dosing interval and a predetermined dose (dosage) that will be described in detail below, the IL-31 antagonist can be intended to be administered repeatedly in equal amounts at the same dosing interval.

[0597] In one embodiment, the lyophilized preparation and the solution preparation of the present disclosure can be used for preventing and / or treating itching caused by atopic dermatitis.

[0598] In yet another embodiment or another embodiment, the lyophilized preparation and the solution preparation of the present disclosure can be used to improve sleep disorders caused by atopic dermatitis, where the sleep disorders may be caused by itching caused by atopic dermatitis. The improvement of sleep disorders can be characterized, for example, by an increase in the time from falling asleep to waking up and / or a decrease in the sleep latency (the time from going to bed to falling asleep).

[0599] In yet another embodiment or another embodiment, the lyophilized and solution formulations of the present disclosure can be used to inhibit at least one symptom caused by atopic dermatitis selected from the group consisting of flushing, induration, papules, edema, exfoliation, and lichenification.

[0600] In one embodiment of the present disclosure, the prevention and / or treatment of atopic dermatitis can refer to, but is not limited to, for example, administering a drug or the like to a subject currently exhibiting atopic dermatitis or various symptoms caused by atopic dermatitis (e.g., itching, flushing, induration, papules, edema, exfoliation, lichenification, decreased quality of life, and sleep deprivation) to inhibit one or more of these symptoms, and / or for example, administering a drug or the like to a subject who has previously suffered from atopic dermatitis or various symptoms caused by atopic dermatitis to eliminate the development of one or more of these symptoms or reduce their incidence. As long as it improves any one of the various symptoms caused by atopic dermatitis, even if it cannot prevent and / or treat atopic dermatitis itself, the prevention and / or treatment of atopic dermatitis can be judged or determined to be useful for prevention and / or treatment.

[0601] Subjects who may have atopic dermatitis can be subjects who have previously had atopic dermatitis and may be at risk of symptom recurrence, or can be subjects suspected of having atopic dermatitis before a doctor or the like makes a diagnosis or determines that the subject has atopic dermatitis, but is not limited thereto.

[0602] In one embodiment, in some cases, the prevention and treatment of atopic dermatitis can be interpreted synonymously.

[0603] It is known that the IL-31 antagonist (CIM331) used in this example showed an improvement in sleep efficiency in the IL-31 antagonist-administered group in a single subcutaneous dose study of IL-31 antagonists in atopic dermatitis patients (WO 2016 / 167263).

[0604] Although atopic dermatitis is not necessarily a life-threatening serious disease, the symptoms associated with this disease can significantly affect daily life. In particular, pruritus (which is the most typical symptom) is an unpleasant sensation that can significantly reduce the quality of life (QOL) of patients and is reported to disrupt patients' sleep (Zuberbier T, Orlow SJ, Paller AS, Taieb A, Allen R, Hernanz-Hermosa JM, Ocampo-Candiani J, Cox M, Langeraar J, Simon JC. Patient perspective on the management of atopic dermatitis. J Allergy Clin Immunol 2006; 118: 226-32). In addition, when the patient is a child, there is a great burden not only on the affected child but also on the parents. It is reported that parents of children with moderate or severe atopic dermatitis spend 3 hours per day on treatment and lose 1 to 2 hours of sleep per day (Su JC, Kemp AS, Varigos GA, Nolan TM. Atopic eczema: its impact on the family and financial cost. Arch Dis Chil 1997; 76: 159-62).

[0605] Accordingly, in another embodiment, the present disclosure relates to a lyophilized preparation and a solution preparation for preventing and / or treating atopic dermatitis, which comprise an IL-31 antagonist as an active ingredient, and which are further used for improving sleep disorders caused by atopic dermatitis. Alternatively, in a further embodiment or another embodiment, the present disclosure relates to a lyophilized preparation and a solution preparation for improving the QOL reduction caused by atopic dermatitis. Improvement of sleep disorders can be characterized, for example, by an increase in the time from falling asleep to waking up and / or a decrease in the sleep latency (the time from going to bed to falling asleep).

[0606] As used herein, the recitation "repeated administration in equal amounts at the same dosing interval" means that the dose of the IL-31 antagonist of the present disclosure initially administered to a subject (initial dose) is equal to the successive doses of the IL-31 antagonist administered subsequently (i.e., the doses administered successively after the initial dose), and the IL-31 antagonist is administered at equal dosing intervals (the intervals between doses). Specifically, for example, the above description refers to the interval between the administration of the initial dose and the administration of the first successive dose, or each interval between the administration of the nth (n is an integer greater than 1) successive dose and the administration of the (n + 1)th successive dose being equal, and the doses being equal. Those skilled in the art will understand that for a determined dosing interval (e.g., every 4 weeks when the dosing interval is determined to be every 4 weeks), each dosing interval has a "tolerable range", and those skilled in the art can decide the tolerable range as appropriate.

[0607] In the present invention, the term "stable antibody-containing formulation" refers to a formulation in which it is difficult to generate aggregates and / or components having charge heterogeneity from proteins such as antibodies, that is, a formulation in which a deterioration reaction is difficult to occur in the formulation, and the deterioration reaction includes the generation of insoluble aggregates, soluble aggregates, and components having charge heterogeneity.

[0608] "Component having charge heterogeneity" refers to a component having a protein surface charge different from that of the main component due to deamidation, oxidation, hydrolysis, etc.

[0609] The amount of aggregates can be measured by size exclusion chromatography (SEC), SDS polyacrylamide gel electrophoresis (SDS-PAGE), capillary SDS gel electrophoresis (CE-SDS), dynamic light scattering (DLS), light obscuration automatic particle counter (HIAC), flow imaging, analytical ultracentrifuge (AUC), etc., and in the present invention, it is preferably measured by size exclusion chromatography (SEC). It is considered that as the measurement conditions, a chromatographic column (TOSOH, TSKgel G3000SWXL) is used, and 50 mmol / L phosphate buffer (pH 7.0), 300 mmol / L sodium chloride, and 0.05% sodium azide are used as the mobile phase, and the sample is measured at a flow rate of 0.5 mL / min, but the conditions are not limited thereto. In one embodiment, the amount of aggregates is measured by the method described in the examples herein.

[0610] Components with charge heterogeneity can be measured by ion exchange chromatography (IEC), specifically cation exchange chromatography or anion exchange chromatography, isoelectric focusing, etc. In the present invention, it is preferably measured by anion exchange chromatography. The amount of components with charge heterogeneity in a sample can be measured by ion exchange chromatography (IEC) using a chromatographic column (TOSOH, TSKgel DEAE-NPR), using 25 mmol / L Tris-HCl buffer (pH 7.5) as mobile phase A and 25 mmol / L Tris-HCl buffer (pH 7.5), 250 mmol / L sodium chloride as mobile phase B, with a flow rate of 1.0 mL / min, but the method is not limited thereto. In one embodiment, the components with charge heterogeneity are measured by the method described in the examples herein.

[0611] In the present invention, "polypeptide" generally refers to peptides and proteins having a length of about 10 amino acids or longer. Usually, they are polypeptides of biological origin, but are not particularly limited thereto, and may be, for example, polypeptides containing artificially designed sequences. In addition, they may be any naturally occurring polypeptides, synthetic polypeptides, recombinant polypeptides, etc. In addition, fragments of the above polypeptides are also included in the polypeptides of the present invention.

[0612] The term "antibody" is used in the broadest sense and includes monoclonal antibodies, polyclonal antibodies, dimers, multimers, multispecific antibodies (e.g., bispecific antibodies), antibody derivatives, and modified antibodies (Miller K et al. J Immunol. 2003, 170(9), 4854-61), as long as they exhibit the desired biological activity. Antibodies can be murine antibodies, human antibodies, humanized antibodies, chimeric antibodies, or antibodies from another species, or artificially synthesized antibodies. The antibodies disclosed herein can be of any type (e.g., IgG, IgE, IgM, IgD, and IgA), class (e.g., IgG1, IgG2, IgG3, IgG4, IgA1, and IgA2), or subclass of immunoglobulin molecules. Immunoglobulins can be derived from any species (e.g., human, murine, or rabbit). The terms "antibody", "immunoglobulin", and "immunoglobulin" are used interchangeably in the broad sense.

[0613] Recombinant antibodies produced by using genetic engineering techniques can be used as antibodies. Recombinant antibodies can be obtained by: cloning the DNA encoding the antibody from a hybridoma or antibody-producing cells such as antibody-producing sensitized lymphocytes; inserting it into a vector; and then introducing it into a host (host cell) to produce the antibody.

[0614] The antibodies of the present invention can be produced by methods known to those skilled in the art. Specifically, DNA encoding the target antibody is inserted into an expression vector. The insertion into the expression vector is such that the expression will be under the control of expression regulatory regions such as enhancers and promoters. Next, the host cell is transformed with the expression vector to express the antibody. In this case, an appropriate combination of host and expression vector can be used.

[0615] The antibodies of the present invention thus obtained can be separated from inside or outside the host cell (such as in the culture medium, etc.) and purified into a substantially pure and homogeneous antibody. The antibodies can be separated and purified by methods commonly used for separating and purifying antibodies, and these methods are not restricted in any way. For example, the antibodies are separated and purified by appropriately selecting and combining column chromatography, filtration, ultrafiltration, salting out, solvent precipitation, solvent extraction, distillation, immunoprecipitation, SDS-polyacrylamide gel electrophoresis, isoelectric focusing, dialysis, recrystallization, etc.

[0616] The inventors of the present invention studied the effects of various additives through thermal acceleration tests to evaluate the stability of samples containing the above anti-IL-31RA antibody (CIM331) during storage. As a result, the inventors found that by preparing a lyophilized preparation from a solution added with arginine hydrochloride and sucrose or trehalose, compared with when they do not contain a stabilizer or a filler (filler), when sodium chloride is added as a stabilizer, or when other sugars are added as a filler, aggregate formation is inhibited. The inventors also found that subvisible particle formation and aggregate formation are inhibited by adding poloxamer 188 and / or polysorbate 20, which are nonionic surfactants, to the antibody-containing solution. In addition, the inventors found that in the antibody-containing solution containing arginine hydrochloride, sucrose or trehalose and a nonionic surfactant, aggregate formation and components with charge heterogeneity are inhibited at pH 6 to pH 8.

[0617] The concentration (amount) of arginine in the preparation of the present invention is preferably 45 mM to 150 mM. Examples of the arginine concentration (amount) include 45 mM, 75 mM, 92 mM, 102 mM, and 150 mM.

[0618] The solution pH of the preparation of the present invention is preferably 6 to 8, more preferably 6.5 to 7.5, and even more preferably 7.

[0619] The preparation of the present invention may contain, for example, Tris buffer as a buffering agent. Tris buffer includes, for example, tris(hydroxymethyl)aminomethane and / or its salts, such as tris(hydroxymethyl)aminomethane-hydrochloride, tris(hydroxymethyl)aminomethane-aspartate, tris(hydroxymethyl)aminomethane-glutamate or tris(hydroxymethyl)aminomethane-acetate. The amount of Tris buffer added to the preparation of the present invention is preferably from 6 mM to 20 mM, for example, 6 mM, 10 mM, 12.3 mM, 13.6 mM or 20 mM.

[0620] Surfactants contained in the preparation of the present invention are, for example, polysorbate 20 (PS20) and Pluronic F-68 (poloxamer 188: polyoxyethylene(160)polyoxypropylene(30)glycol), and poloxamer 188 is particularly preferred. The amount of poloxamer 188 (or PX188) added to the preparation of the present invention is preferably from 0.15 mg / mL to 0.5 mg / mL. Examples of the amount of poloxamer 188 added to the preparation include 0.15 mg / mL, 0.25 mg / mL, 0.31 mg / mL, 0.34 mg / mL and 0.50 mg / mL.

[0643] Examples

[0644] Definitions

[0645] [Experimental methods]

[0646] To adjust the pH value, the formulations prepared in each example contained 6 mmol / L to 20 mmol / L Tris-HCl, which did not contribute to the stability of CIM331, an anti-IL-31RA antibody that comprises the H chain of SEQ ID NO: 9 and the L chain of SEQ ID NO: 10.

[0647] Thermal accelerated studies of the solution formulations were conducted at 40°C / 75% RH. Meanwhile, since lyophilized formulations are generally more stable, thermal accelerated studies of the lyophilized formulations were conducted at a higher temperature, 50°C 75% RH.

[0648] In Example 3, to verify the effect of nonionic surfactants, vibration studies were conducted.

[0649] [Analytical methods]

[0650] Regarding the measurement of the amount of CIM331 aggregates, considering the accuracy of the analytical method, when the difference in the percentage of aggregates is 0.07% or higher, a significant difference can be judged to exist.

[0651] Regarding the measurement of the components of CIM331 with charge heterogeneity, considering the accuracy of the analytical method, when the difference in the basic region is 1.3% or higher, the difference in the main region is 1.4% or higher, and the difference in the acidic region is 0.6% or higher, a significant difference can be judged to exist.

[0652] Due to the different stabilities between solution formulations and lyophilized formulations, the results of the analytical method cannot be similarly interpreted between solution formulations and lyophilized formulations.
